When an animal, such as a dog or cat, is sick or unwell, its first natural instinct is to refuse food. Their body automatically cuts down appetite till they recover. They may drink water, but nothing else. This is bodys intelligence taking over to heal and recover.Intuitive eatingHumans arent any different. At least, intuitively. All of us are products of nature and we have been designed the same. When we call in sick, the first thing that happens is that our appetites shut down too. Our taste of mouth changes and our sensitivity to smell and taste is numbed. This is our bodys intelligence and subtle biofeedback trying to tell us that its time we give our body some rest.

This is fasting in a way and has been practised since the longest time across all religions. Fasting is inbuilt in us and is considered medicinal if you actually go back and read its history. It is our bodys uncomplicated way of cleaning and healing. Unfortunately, we have moved too far from nature and our natural instincts. We are constantly eating and munching even when sick, thereby compromising our own immunity and masking the inbuilt mechanism to heal.Take a break

The best beauty products from the 2020 Beauty Crush Awards - Yahoo Lifestyle

Skin Stem Cells Comments Off on The best beauty products from the 2020 Beauty Crush Awards – Yahoo Lifestyle | February 29th, 2020

Numerous revelations about the world have been made in various forms throughout history. Researchers and scientists have continuously managed to discover new ways we can understand the world around us.

Major scientific breakthroughs have been made that helped improve our way of life and will make it easier for us to achieve even more amazing innovation eventually. The 21st century was especially fruitful for the advancements in technology and science. Many of the essential revelations in history were made during the last 100 years. This article will attempt to name the most important ones.

In 2015, the National Aeronautics and Space Administration managed to find evidence that proves that there is liquid water on Mars. Scientists were aided by the first spectrometer provided by NASA, called the Mars Reconnaissance Orbiter.

With its help, they were able to detect hydrated salts all over the distant planet. The hydrated salts are more prevalent during the warmer seasons, which means that water is a crucial ingredient in their development.

Many scientists believe this to be the most crucial discovery of the 21st century. Since Albert Einsteins theory of relativity was published, the thought of time travel has excited scientific minds all over the world.

The LIGO (Laser Interferometer Gravitational-Wave Observatory) project in the United States is responsible for the detection of gravitational waves, which would imply that with enough research time travel could be possible. Journey to the earliest parts of our universe does not seem as impossible as before since this discovery.

Proof of the existence of Dark Matter was found in 2006 by a team of researchers, led by Maxim Markevitch of the Harvard-Smithsonian Center for Astrophysics in Cambridge. They proved its existence by measuring the location of mass that gets created when galaxies collide. Specific clusters of mass get disconnected, and a large amount of visible matter is what makes up dark matter. While this sounds overly complex, the important thing to remember is that this proves that dark matter makes up for 68% of the universe.

Through stem cell research, we can provide better access to organs for patients, meaning that patients no longer need to wait for donors, making it easier to cure certain conditions. Stem cells make it possible to grow an indefinite number of cells of the same type, but other types of cells also arise from that process. This means that it is possible to regenerate organs using skin cells. In the future, the discovery could make it so that the organs needed for treatment are created in a laboratory.

The process of face transplantation uses tissues of a dead person to replace another persons face. It is a complicated process that was first successfully performed in France in 2005. This transplant was only partial, but the first full-face transplant happened only five years later in Spain.

Since then, people with significant congenital disabilities or facial disfigures caused by diseases or burns have had this procedure performed on them in multiple countries. What seemed like science fiction in the 1990s is a reality now.

HIV is considered to be one of the deadliest viruses in the history of humankind. While we still have not found a cure for AIDS, the disease that is a result of an HIV that has advanced too much, we did manage to improve the treatment of HIV.

With the new methods, some of which were developed in Germany, patients with HIV can live longer, almost being able to lead healthy lives. With these exciting advancements, millions of lives have been saved, and it is only a matter of time before we find a complete cure.

Scientists atthe Massachusetts Institute of Technology (MIT)managed to find a way to create false memories and plant them into the brains of mice. While this enormous scientific breakthrough can help us better understand the concept of mind and help us with dealing with mental health issues, it can still be problematic.

It does seem like a scene out of an old science fiction movie, but with this advancement, it could be possible to manipulate a persons memory, and who knows what consequences that could have.

Scientists at the University of Twente have developed robotic body parts using biomechanics. They managed to create robotic arms that can make life easier for people with severe muscular dystrophy. They also implemented previous research on prosthetics in creating these limbs. These robotic body parts could prove to be extremely helpful for wounded soldiers, people suffering from disabilities or older people.

A photon was teleported into space with the help of a laser beam by Canadian scientists. This process is called quantum teleportation, and it can be used to transport information about something, not its physical state. However, it is a step in the right direction of possibly making teleportation of physical matter possible someday.

The process itself was incredibly hard and required extreme precision. Photons are tiny, meaning that it will be a while until we can successfully teleport larger items.

Although the World Wide Web originated much earlier, it was not until the 21st century that we saw everything the internet is capable of. And it is a fitting way to end this list because it impacted more lives than anything else. Thanks to the internet, we can do things we could only imagine 20 years ago, basically from anywhere in the world. We can access any information, watch every movie in existence, or talk to people halfway around the world. It is the discovery of all the possibilities of the internet that made this century what it is, at least for now.

Where and when was the first face transplant procedure performed?

The first face transplant procedure was performed in France in 2005.

10 Of The Biggest World Revelations In The 21st Century - World Atlas

Skin Stem Cells Comments Off on 10 Of The Biggest World Revelations In The 21st Century – World Atlas | February 29th, 2020

There is new hope for patients with a rare autoimmune disorder. In mild cases, scleroderma causes areas of hardened skin. But in severe cases, it can also cause deadly hardening of internal organs like the lungs.

A transplant typically used to treat cancer is having remarkable results for patients who had little hope of surviving.

A year ago, Chuck Beschta couldn't walk more than a few minutes without stopping to rest.

"Just going out and doing normal activities outside raking the lawn, mowing the grass, shoveling the driveway, whatever, snow blowing those became impossible," he said.

After months of testing, he was diagnosed with severe scleroderma, which was hardening his skin. But even worse, it was hardening his lungs, making it hard to breathe.

"He was getting worse despite the best therapy we had to offer," University of Wisconsin rheumatologist Dr. Kevin McKown said.

McKown recommended a stem cell transplant newly approved for scleroderma to reboot Beschta's immune system.

"There's a process by which they try to remove the autoreactive immune cells, the cells that are caught in the immune process, and then they infuse that back in and hope that the body will basically take up and graft that immune system," McKown said.

Beschta saw almost immediate results. His skin was softer and his breathing improved. He hopes his scleroderma has been cured.

"I think we can be optimistic, and so far the people who have been followed out as far as 10 years out don't seem to be getting it back," McKown said.

Without a transplant, less than half the patients who have diffuse scleroderma and severe lung disease live 10 years past diagnosis.

Stem cell transplants are commonly used to treat leukemia and lymphoma, cancers that affect the blood and lymphatic system.

MEDICAL BREAKTHROUGHSRESEARCH SUMMARYTOPIC: NEW THERAPY FOR SCLERODERMAREPORT: MB #4698

BACKGROUND: Scleroderma is an autoimmune rheumatic disease where an overproduction of collagen produced in the body tissues causes the skin and internal organs to harden. The symptoms and effects range by person, but some common symptoms include hardened patches of skin (locations on the body vary,) painful and numb-feeling fingers and toes, and sharp internal pain in the esophagus, intestines, heart, lungs, or kidneys. Women are four times as likely to have scleroderma and the onset is between 30 and 50 years of age. However, anyone from infants to the elderly can have scleroderma. Possible risk factors include having certain gene variations as other family members, ethnic groups, exposure to certain medications or drugs, and already having another autoimmune disease, like rheumatoid arthritis, lupus or Sjogren's syndrome. (Source: https://www.scleroderma.org/site/SPageNavigator/patients_whatis.html;jsessionid=00000000.app30132b?NONCE_TOKEN=9B76519DF6B5819859319F0B63B805C9#.XheCGVVKhaQ , https://www.mayoclinic.org/diseases-conditions/scleroderma/symptoms-causes/syc-20351952 )

DIAGNOSING: A physical exam will be conducted as well as a blood test to check for elevated levels of antibodies the immune system produced. The doctor will also take a sample of skin to be tested in the lab. If there are complaints about internal pain, the doctor may run other tests, including imaging, organ function, and other blood tests.

NEW TECHNOLOGY: A new stem cell transplant that's commonly known to treat cancer is improving the quality and quantity of life for those with scleroderma. Rheumatologists at University of Wisconsin Health tested the treatment since they have already been conducting bone marrow transplants for decades. Surgeons take out a sample of the patient's bone marrow, isolate the stem cells, and use radiation and chemotherapy to clean out their immune system. The same stem cells are later injected back into the patient's immune system with the hope that new cells will grow and the system is rid of the bad ones. The process is dangerous when the cells are taken out because the patient's immune system is more vulnerable, making infections more likely to occur. However, after four and a half years, 79% of patients that underwent the treatment were alive without serious complications compared to 50% that were treated with the original drugs.

A mum has shared the emotional experience of meeting the stranger who saved her son's life.

Alfie Commons, now aged four, was just seven months old when he was diagnosed with leukaemia in 2016.

After three rounds of chemotherapy failed, Alfie received a life-saving bone marrow donation from a school teacher in Germany, who recently made the trip to the UK to meet him.

Alfie's mum, Lorna Commons, 40, of Toton has spoken about the experience in the hope it will encourage more people to sign up to become potential donors.

Looking back to the day of diagnosis, she said Alfie had been to his GP for a third time in February 2016 after suffering a cold since Christmas.

She said: "The GP told us to go to A&E for further tests as he was a little concerned.

"We got to Queen's Medical Centre in the morning and by early evening, we had the diagnosis; Alfie had infant acute lymphoblastic leukaemia (ALL)."

Ms Commons, who works in HR, added: "Even now, four years down the line, I still feel the emotions of that day. Nothing can prepare you."

The plan was to treat Alfie with chemotherapy, but after the first round failed, Ms Commons was told his only chance of survival was to get a bone marrow transplant.

The family was told Alfie was unlikely to leave hospital for the next six months.

She added: "Worse was to follow, his second course also failed and on the same day, we were told that Alfies nine-year-old brother, Billy, wasnt a bloodstemcellmatch for him either.

"The fear of losing Alfie was overwhelming, I felt helpless but I had to carry on for Alfies sake.

The transplant could not go ahead without the cancer being near enough eradicated and even when the good news came that a donor had been located, Alfie still had a mountain to climb.

After a third failed round of chemotherapy, Alfie was put on a trial immunotherapy drug as a '"last ditch attempt". Against all the odds, it worked.

"I think at that point all the doctors and nurses were preparing us for the worst. Your head has to go there," Ms Commons said.

"But then the cancer went, and it was enough to give us the bridge to getting the transplant done."

While the transplant was a success, Alfie suffered for months with Graft versus Host Disease (GvHD) on his skin and in his gut, which is the body's reaction to the new stem cells.

However, doctor's were encouraged the body was gradually accepting the cells and beginning to produce cells of their own.

On February 19, Alfie and his mum were able to meet the woman who saved his life after she made the 600-mile trip.

Christin Bouvier, 34, from Schwerin in Germany, was matched with Alfie after she registered in 2010 with DKMS, a charity dedicated to the fight against blood cancer.

The school teacher had been on the bloodstemcellregister for a number of years before she was contacted and tested as a match for Alfie.

Ms Bouvier said: When they told me that the recipient was a baby I just cried.

"Its a moment that is always with me and whenever I feel a bit down, I think back to it as it always brings me so much happiness!"

Ms Commons said she had been able to contact Ms Bouvier anonymously, as per UK law, but they were permitted to meet two years after the transplant.

Ms Bouvier added: It was always a dream to meet Lorna and Alfie and I never thought it would happen I was so delighted when Lorna invited me. I was very nervous but also very excited to meet them both in person.

"I knew the meeting would be one of those very special moments in my life."

Ms Commons feels the meeting has meant a new chapter has begun in both hers and Alfie's life and she is now focussed on the positives.

She added: "For something so small, there really is no greater gift than being a donor - I get to see my child grow up. To meet Christin, I was able to say 'this is what you've done'.

"We will be in each other's lives forever now - Alfie has her DNA in his blood. But Christin and I also share a special bond, we're just so similar and some people say we even look like sisters.

Alfie is such a special little boy and I truly believe that this story can make a real difference and save more lives.

"There is a match out there for everyone with blood cancer, people just need to come forward and register."

Anyone aged between 17-55 and in general good health can go on standby as a potential lifesaver.

Scientists believe that humans will soon be able to recover from injuries such as broken spines, as treatment looks to boost the body's ability to heal itself.

A new study in the journal Regenerative Medicine describes how scientists were able to stimulate the self-repair response in rats.

Rats in the study were given two drugs, one of which is usually given to bone marrow transplant patients, and another which is used for bladder control.

This cocktail caused the rats' bone marrow to produce a greater number of mesenchymal stem cells, the cells which can develop into bone tissue.

As a result, enhanced calcium binding was seen at the site of the rats' spinal injuries, speeding up the production of new bone as well as healing wounds.

The study's authors hope that one day, such treatments will work on humans.

"We know that when bones break they will heal, and this requires the activation of stem cells in the bone," study co-author Sara Rankin from the National Heart and Lung Institute at Imperial College London, said in a statement.

"However, when the damage is severe, there are limits to what the body can do of its own accord.

"We hope that by using these existing medications to mobilise stem cells, as we were able to do in rats in our new study, we could potentially call up extra numbers of these stem cells, in order to boost our bodies' own ability to mend itself and accelerate the repair process."

Both drugs tested on rats are already widely used, so researchers are hopeful human trails can begin soon.

If these trials produce the same results as those seen in rats, then it's hoped the treatment could help to not only repair spinal injuries but also speed up the rate at which broken bones heal and mend damaged tissues in other organs.

Dr Tariq Fellous, first author of the research, said: "We first need to see if these medications release the stem cells in healthy volunteers before we can test them in patients with fractures.

"We have the drugs and know they are safe to use in humans we just need the funding for the human trials."

Dr Andia Redpath, who also co-authored the paper, added that repurposing existing medicines - so-called Regenerative Pharmacology - could have major potential as an efficient and cheaper way of treating diseases.

"Rather than devising new stem cell treatments from scratch that involve lengthy and expensive trials, our approach harnesses the power of the body's own stem cells, using existing drugs.

"We already know the treatments in our study are safe, it's now just a matter of exploring further if they help our bodies heal."

Stem cells are providing incredible new medical breakthroughs all the time.

Earlier this month, scientists trialled 3D-printed skin containing stem cells to treat burns victims .

The most emotional issue my patients have is hair loss, says New York dermatologist Cheryl Karcher, MD below a jaw-dropping before-and-after photo shared to her Instagram page. On the left half of the photo shared is a young womans exposed hairlinethe hair is so thin and sparse, the entire scalp is visible wherever your eye is drawn. On the right side of the photo, the same woman, but with an almost unbelievable amount of thicker hair, and, somehow, a sense of renewed confidence.

The secret? A little thing called nanofat.

In the past we only had PRP to offer that had to be done three times or more. Sometimes it would work, sometimes it didnt. Now we have nanofat hair restoration, which needs to be done just once, and is much more effective way to treat hair loss and grow hair, explains Dr. Karcher.

So what is nanofat? According to Dr. Karcher, its derived from our own adipose tissue, whereas the ever popular PRP is derived from our blood. Nanofat includes adipose-derived stromal vascular fraction, which contains stem cells as well as growth factors. PRP contains the growth factors released from platelets in the blood, she adds. The procedure itself involves extracting anywhere from 20 to 40 millilitersof fat, usually from the abdomen, then processing it through mechanical filters, before injecting.

Like PRP, the possibilities of what nanofat can help with doesnt stop at the hairline. After the nanofat is processed to the point where there is no fat left, only stem cells and growth factors, it is injected into the scalp, the face, the neck, the decollete, or to improve sun damage, skin pigmentation, decrease wrinkles, and of course grow hair, says Dr. Karcher.

When nanofat is used for hair restoration, Dr. Karcher says she first injects the nanofat, then injects the patients PRP on top of it to act as a fertilizer for the nanofat. Perhaps the best part? Theres little to no painDr. Karcher says the most pain patients feel is during the PRP injections, so the scalp is numbed topicallyand no downtime. When nanofat is used on the face, chest or other areas, Dr. Karcher warns there may be some downtime of erythema and swelling or bruising. If injected for [skin] rejuvenation via microneedling the downtime is only about 48 hours.

While Dr. Karcher has seen unparalleled results from nanofat hair restoration, it is only ideal for patients who have some hair still present on the scalppatients who are completely bald may not be ideal candidates for the procedure. The only time I ever use PRP for hair restoration now is in a patient that doesnt have enough fat to harvest. The nanofat is just one treatment and the results seem to be superior. However, as La Jolla, CA plastic surgeon Robert Singer, MD notes, there is no safety or efficacy data surrounding nanofat treatment as of press time.

Recent developments in the field of stem cell research are paving a path towards a radical shift in the way we diagnose and treat dementia. Stem cells have excited scientists for years and research groups across the globe are using them to advance modern medicine. Using stem cells to aid the fight against dementia is perhaps one of the most critical applications of the technology. Dementia is the leading cause of death in the UK, sixth in US and fifth globally, with an estimated 50 million people currently affected.

The term dementia does not relate to a single disease, but more an array of symptoms that can arise from multiple conditions. The most common is Alzheimers disease (AD) which accounts for up to 80% of all cases. Dementia itself is caused by the death of cells that make up the complex circuitry of our brains and an eventual loss of large portions of the brain. Patients suffering with dementia often exhibit the same general symptoms such as confusion, memory loss and an inability to perform day to day functions. It is a debilitating condition that often strikes the most vulnerable members of society and, consequently, many research groups around the globe work to try to understand dementia-causing diseases to provide better diagnostic and treatment platforms.

In 2007, a research group at Kyoto University in Japan published a study with the potential to change the face of research into dementia along with many other fields. Professor Shinya Yamanaka and his research team developed a method whereby stem cells (cells that can be transformed/differentiated into cells from any tissue) could be generated from a sample of skin. The study, which resulted in a 2012 Nobel Prize for Prof. Yamanaka, demonstrated that skin cells could be isolated from a patient and genetically reprogrammed into induced pluripotent stem cells (iPSCs). In short, this technology made it possible to generate and study brain cells from a patient with dementia without having to remove any of their brain. All they would need to do is provide scientists with a sample of skin.

Since this development, research groups around the globe have started using iPSCs from many patients with dementia in order to understand the biological mechanisms that underlie disease. Dr Eric Hill runs a research group at Aston University in the UK that specializes in iPSCs for dementia research and he had the following to say about the technology:

Its really exciting because it allows us to study cells with genetic mutations that are patient specific. We can get a much better picture of what is actually happening in the brains of these patients. We can now generate all the different cell types found in the human brain and understand how they function together and map the changes that result in disease.

The latter was perhaps most powerfully demonstrated in a study published by a team at the University of North Carolina, led by Professor Hansang Cho. The team was able to generate three key cell subtypes that play important roles in brain function; study the impact of mutations associated with Alzheimers disease; and even replicate some of the core malfunctions found to trigger disease in the brains of patients.

Studies like this are of significance because a large part of the focus in dementia research is on trying to understand how such changes in function arise. When a patient is diagnosed with a disease such as Alzheimers it is often too late for effective treatment. Scientists, instead, seek to elucidate those early changes in brain cell function in order to diagnose patients earlier to give more time for treatment. It is very much a case of prevention being better than a cure. Dr Hill provided an encouraging statement regarding this:

When we generate brain cells from iPSCs the cells we get are developmentally very young. What is interesting is the fact we still see differences between cells from dementia patients versus healthy patients suggesting we could find markers to help us detect and prevent disease some years before it develops.

Despite such promise, however, iPSCs have yet to provide the field of dementia research with that big break. Multiple treatments have progressed into clinical trials since the technology first emerged but no therapies have been approved. Drugs that show promise in the lab fail to deliver on their potential in patient clinical trials, sending researchers back to square one.

We should not be disheartened by this, however, and should instead view it as space into which the technology of using iPSCs to study dementia can grow. A lot of drugs fail in clinical trials because the platforms used to run initial tests dont provide scientists with a wide enough perspective of how those drugs will influence human cells. Additionally, many preclinical studies use animals with dementia-causing disease artificially induced into them. Studies like this often fail to translate into humans because the initial data is not from a human perspective. This is where researchers like Dr. Hill think iPSCs can provide us with an advantage:

iPSCs could provide us with much better platforms for screening drugs to treat and prevent these diseases. They can really add to what we already have, and while we might not be able to grow a full human brain, we can generate the cells that provide the building blocks for one. They give us the chance to screen new therapies more efficiently, better test their effectiveness and reduce the amount of animal use in dementia research.

Dr Hill is not alone in seeing the promise of using iPSCs to find better treatments for preventing the progression of dementia. Multiple research groups around the world have shown the potential of iPSC-derived brain cells for studying the effectiveness of new therapies.

In the last 12 months we have observed a wave of new studies using iPSCs to try to develop better treatments for diseases like Alzheimers, Parkinsons, Huntingtons disease and ALS. From studies in the University of California identifying cholesterol metabolism as a potential target to treating Alzheimers to studies in Luxembourg helping us find better treatments for Parkinsons, it is easy to see why the global effort to get that big break from iPSCs continues to gain interest. We might still be waiting for that next Noble Prize-winning discovery that will improve the lives of millions of patients but the collective effort of iPSC research groups across the world brings us a step closer with every study they publish. Dementia may, one day, be a thing of the past and iPSC research will likely be a significant part in getting us there.

- Axol Softwave Therapy is a new treatment for erectile dysfunction (ED) and for men who want enhanced sexual performance

- The in-office treatment is non-invasive, safe, and effective with virtually no side effects

- Axol Therapy uses low-intensity sound waves

- Axol Therapy is an alternative to ED medications, surgical implants, penile pumps, and injections

DENVER, Feb. 24, 2020 /PRNewswire/ -- The men's sexual health specialists at Colorado Urology now offer an exciting new treatment option for men living with erectile dysfunction (ED) called Axol Softwave Therapy. This safe and non-invasive treatment option is helping many men with ED achieve spontaneous and natural erections without the help of medications. The therapy can also be used to enhance a man's sexual performance.

Colorado Urology (PRNewsfoto/Colorado Urology)

About 5 in 10 men experience erectile dysfunction (ED) at some point in their lives. First-line therapies often include oral medication to help men achieve an erection. Now, Axol Therapy is providing a safe and effective alternative.

This non-invasive procedure uses gentle full-spectrum, low-intensity sound waves that stimulate revascularization, a process in which new blood vessels form. Axol Therapy promotes improved blood flow to the penis, reduces inflammation, and stimulates the migration of the body's stem cells for long-term healing. The new treatment is helping men to achieve natural erections without ED medications, pumps, injections, or penile implants.

Learn about Axol Softwave Therapy at Colorado Urology: https://www.coloradouro.com/specialties/axol-softwave-therapy/.

Axol Therapy How it Works

Axol Therapy is a modern approach to healing the body by using four types of energy: Heat, Electrohydraulic, Acoustic, and Light (HEAL). Unfocused acoustic waves are delivered to the shaft of the penis using a treatment wand that features a patented unfocused electrohydraulic acoustic wave.

The pulsed acoustic waves are delivered through the skin into the tissue to open and repair aging blood vessels, stimulate new blood vessel growth, restore blood flow, and improve erectile quality. Axol Therapy typically takes only 20 minutes, once a week, for a total of six sessions in the physician's office.

How Well Does Axol Therapy Work?

For men who are the right candidates, Axol Therapy is a safe and effective option without the side effects often experienced with oral medications. Most patients can get the quality, rigid erections they once had with Axol Therapy's gentle acoustic pulse treatment within just six office visits. Incremental improvement in erectile function may be seen after just a few sessions.

Restoring Vitality and Quality of Life

There are a number of significant benefits to Axol Therapy. For men who are candidates for this treatment option, a future without erectile dysfunction is perhaps the biggest one. The restoration of a man's vitality and spontaneous active sex life are also major benefits of this exciting new treatment.

Medical ResearchThe belief that acute stress can turn hair gray is a popular one, but until now it hasnt been scientifically proven.

But findings that appeared in the publication Nature indicate that the belief may be more than a myth. The study, which used mice as models, was funded in part by the National Institutes of Healths National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and other NIH components.

Hair color is determined by cells called melanocytes, which produce the pigment melanin. New melanocytes are made from melanocyte stem cells that live within the hair follicle at the base of the hair strand. As we age, these stem cells gradually disappear. The hair that regrows from hair follicles that have lost melanocyte stem cells has less pigment and appears gray.

A research team, led by Dr. Ya-Chieh Hsu of Harvard University, used mice to examine stress and hair graying. The mice were exposed to three types of stress involving mild, short-term pain, psychological stress, and restricted movement. All caused noticeable loss of melanocyte stem cells and hair graying.

Having established a link between stress and graying, the scientists then explored several potential causes, including the role of the stress hormone corticosterone, but altering its levels didnt affect stress-related graying.

The researchers eventually turned to the neurotransmitter noradrenaline, which, along with corticosterone, was elevated in the stressed mice. They found that noradrenaline, also known as norepinephrine, was key to stress-induced hair graying. By injecting noradrenaline under the skin of unstressed mice, the researchers were able to cause melanocyte stem cell loss and hair graying.

Noradrenaline is produced mostly by the adrenal glands. However, mice without adrenal glands still showed stress-related graying. Noradrenaline is also the main neurotransmitter of the sympathetic nervous system, which is responsible for the fight-or-flight reaction in response to stress.

Ultimately, the team discovered that signaling from the sympathetic nervous system plays a critical role in stress-induced graying. Sympathetic nerves extend into each hair follicle and release noradrenaline in response to stress. Normally, the melanocyte stem cells in the follicle are dormant until a new hair is grown. Noradrenaline causes the stem cells to activate.

Using fluorescent labelling, the researchers observed the stem cells change to melanocytes and migrate away from their reserve in the hair follicle. With no remaining stem cells, no new pigment cells can be made, and any new hair becomes gray, then white.

When we started to study this, I expected that stress was bad for the body but the detrimental impact of stress that we discovered was beyond what I imagined, Hsu says. After just a few days, all of the melanocyte stem cells were lost. Once theyre gone, you cant regenerate pigments anymore. The damage is permanent.

The authors highlight the need to further study the interactions between the nervous system and stem cells in different tissues and organs. A news release from the NIH said that the knowledge gained in this work will be useful in future investigations into the impact of stress on the body and the development of new interventions.

Patient Analyses and Safety Data Continue to Underscore Positive Impact of KD025 in cGVHD

Pre-NDA Meeting with FDA Planned for March 2020; Topline Results of Primary Analysis to be Announced in Q2 2020

NEW YORK, NY / ACCESSWIRE / February 23, 2020 / Kadmon Holdings, Inc. (NYSE:KDMN) today announced expanded results from the previously reported interim analysis of ROCKstar (KD025-213), its ongoing pivotal trial of KD025 in chronic graft-versus-host disease (cGVHD). The data were presented today in the oral latebreaker session at the 2020 Transplantation & Cellular Therapy (TCT) Meetings.

As announced in November 2019, KD025 met the primary endpoint of Overall Response Rate (ORR) at the study's planned interim analysis, two months after completion of enrollment. KD025 showed statistically significant and clinically meaningful ORRs of 64% with KD025 200 mg once daily (95% Confidence Interval (CI): 51%, 75%; p<0.0001) and 67% with KD025 200 mg twice daily (95% CI: 54%, 78%; p<0.0001). In the expanded KD025-213 dataset presented today, ORRs were consistent with the previously reported interim analysis across key subgroups, including in patients with four or more organs affected by cGVHD (n=69; 64%), patients who had prior treatment with ibrutinib (n=45; 62%) and patients who had prior treatment with ruxolitinib (n=37; 62%). Three patients achieved a Complete Response. Responses were observed in all affected organ systems, including in organs with fibrotic disease. KD025 has been well tolerated: adverse events were consistent overall with those expected to be observed in cGVHD patients receiving corticosteroids, and no apparent increased risk of infection was observed. Additional secondary endpoints, including duration of response, corticosteroid dose reductions, Failure-Free Survival, Overall Survival and Lee Symptom Scale reductions continue to mature and will be available later in 2020.

"KD025 has been well tolerated and has already demonstrated high response rates in patients with severe and complex cGVHD after a median of five months of follow-up," said Corey Cutler, MD, MPH, FRCPC, Associate Professor of Medicine, Harvard Medical School; Medical Director, Adult Stem Cell Transplantation Program, Dana-Farber Cancer Institute and a KD025-213 study investigator and Steering Committee member.

"We are extremely pleased with the interim outcomes of this pivotal trial of KD025 in cGVHD, which track closely our findings from our earlier Phase 2 study. KD025 achieved robust response rates across all subgroups of this difficult-to-treat patient population, who had a median of four prior lines of therapy, and 73% of whom had no response to their last line of treatment," said Harlan W. Waksal, M.D., President and CEO of Kadmon. "We plan to meet with the FDA for a pre-NDA meeting in March 2020 and to announce topline results from the primary analysis of this trial in Q2 2020."

At the TCT Meetings, Kadmon also presented long-term follow-up data from KD025-208, its ongoing Phase 2 study of KD025 in cGVHD (Abstract #15205). These data were recently presented at the 61st American Society of Hematology (ASH) Annual Meeting and Exposition in December 2019.

About the ROCKstar (KD025-213) Trial

KD025-213 is an ongoing open-label trial of KD025 in adults and adolescents with cGVHD who have received at least two prior lines of systemic therapy. Patients were randomized to receive KD025 200 mg once daily or KD025 200 mg twice daily, enrolling 66 patients per arm. Statistical significance is achieved if the lower bound of the 95% CI of ORR exceeds 30%.

While the ORR endpoint was met at the interim analysis, which was conducted as scheduled two months after completion of enrollment, topline data from the primary analysis of the KD025-213 study, six months after completion of enrollment, will be reported in Q2 2020. Full data from the primary analysis will be submitted for presentation at an upcoming scientific meeting.

About KD025

KD025 is a selective oral inhibitor of Rho-associated coiled-coil kinase 2 (ROCK2), a signaling pathway that modulates immune response as well as fibrotic pathways. In addition to cGVHD, KD025 is being studied in an ongoing Phase 2 clinical trial in adults with diffuse cutaneous systemic sclerosis (KD025-209). KD025 was granted Breakthrough Therapy Designation and Orphan Drug Designation by the U.S. Food and Drug Administration for the treatment of patients with cGVHD who have received at least two prior lines of systemic therapy.

About cGVHD

cGVHD is a common and often fatal complication following hematopoietic stem cell transplantation. In cGVHD, transplanted immune cells (graft) attack the patient's cells (host), leading to inflammation and fibrosis in multiple tissues, including skin, mouth, eye, joints, liver, lung, esophagus and gastrointestinal tract. Approximately 14,000 patients in the United States are currently living with cGVHD, and approximately 5,000 new patients are diagnosed with cGVHD per year.

About Kadmon

Kadmon is a clinical-stage biopharmaceutical company that discovers, develops and delivers transformative therapies for unmet medical needs. Our clinical pipeline includes treatments for immune and fibrotic diseases as well as immuno-oncology therapies.

Stress may play a key role in just how quickly hair goes from colored to ashen.

Scientists have long understood some link is possible between stress and grey hair.

But this new research more deeply probes the exact mechanisms at play.

The researchers initial tests looked closely at cortisol, the stress hormone that surges in the body when a person experiences a fight or flight response.

Its an important bodily function, but the long-term presence of heightened cortisol links to a host of negative health outcomes.

But the culprit ended up being a different part of the bodys fight or flight response the sympathetic nervous system.

These nerves are all over the body, including making inroads to each hair follicle, the researchers reported.

Chemicals released during the stress response causes pigment producing stem cells to activate prematurely, depleting the hairs reserves of color.

The detrimental impact of stress that we discovered was beyond what I imagined, a lead study author said.

After just a few days, all of the pigment-regenerating stem cells were lost.

Once theyre gone, you cant regenerate pigments anymore. The damage is permanent.

But stress isnt the only reason that most people get grey hair.

In most cases, its simple genetics.

Gray hair caused by loss of melanocytes (pigment cells) in the hair follicle.

This happens as we age and, unfortunately, there is no treatment that can restore these cells and the pigment they produce, melanin, a dermatologist told.

Genetic factors determine when you go grey.

There is nothing that can be done medically to prevent this from happening when it is genetically predetermined to happen.

That doesnt mean environmental factors such as stress dont play a role.

Smoking, for instance, is a known risk factor for premature graying.

So kick the habit if you want to keep that color a little longer.

Other contributing factors to premature graying include deficiencies in protein, vitamin B-12, copper, and iron as well as aging due in part to an accumulation of oxidative stress.

That stress prompted by an imbalance between free radicals and antioxidants in your body that can damage tissue, proteins, and DNA.

And some degree of oxidative stress is a natural part of life.

Changes you can pursue to delay premature grays include eating a diet high in omega-3 fatty acids such as walnuts and fatty fish.

It doesnt spend too much time in the skin-damaging and hair-damaging ultraviolet light of the sun, and taking vitamin B-12 and vitamin B-6 supplements.

That said, if you are going gray prematurely, it wouldnt hurt to go have a checkup just in case natural genetic factors arent the sole culprit.

Stress could be a major cause of grey hair - BOL News

Skin Stem Cells Comments Off on Stress could be a major cause of grey hair – BOL News | February 24th, 2020

Researchers from the group of Vlad Cojocaru together with colleagues the Max Planck Institute in Mnster (Germany) have revealed how an essential protein helps to activate genomic DNA during the conversion of regular adult human cells into stem cells.A cells identity is driven by which DNA is read or not read at any point in time. Signaling in the cell to start or stop reading DNA happens through proteins called transcription factors. Identity changes happen naturally during development as cells transition from an undesignated cell to a specific cell type. As it turns out, these transitions can also be reversed. In 2012, Japanese researchers were awarded the Nobel prize for being the first to push a regular skin cell backwards to a stem cell.A fuller understanding of molecular processes towards stem cell therapiesUntil now, it is unknown how the conversion of a skin cell into a stem cell happens exactly, on a molecular scale. Fully understanding the processes with atomic details is essential if we want to produce such cells for individual patients in the future in a reliable and efficient manner, says research leader Vlad Cojocaru of the Hubrecht Institute. It is believed that such engineered cell types may in the future be part of the solution to diseases like Alzheimers and Parkinsons, but the production process would have to become more efficient and predictable.Pioneer transcription factorOne of the main proteins involved in the stem cell generation is a transcription factor called Oct4. It induces gene expression, or activity, of the proteins that reset the adult cell into a stem cell. Those genes induced are inactive in the adult cells and reside in tightly packed, closed states of chromatin, the structure that stores the DNA in the cell nucleus. Oct4 contributes to the opening of chromatin to allow for the expression of the genes. For this, Oct4 is known as a pioneer transcription factor.

The data from Cojocaru and his PhD candidate and first author of the publication Jan Huertas show how Oct4 binds to DNA on the so-called nucleosomes, the repetitive nuclear structures in chromatin. Cojocaru: We modelled Oct4 in different configurations. The molecule consists of two domains, only one of which is able to bind to a specific DNA sequence on the nucleosome in this phase of the process. With our simulations, we discovered which of those configurations are stable and how the dynamics of nucleosomes influence Oct4 binding. The models were validated by experiments performed by our colleagues Caitlin MacCarthy and Hans Schler in Mnster.One step closer to engineered factorsThis is the first time computer simulations show how a pioneer transcription factor binds to nucleosomes to open chromatin and regulate gene expression. Our computational approach for obtaining the Oct4 models can also be used to screen other transcription factors and to find out how they bind to nucleosomes, Cojocaru says.

Moreover, Cojocaru wants to refine the current Oct4 models to propose a final structure for the Oct4-nucleosome complex. For already almost 15 years now, we know that Oct4 together with three other pioneer factors transforms adult cells into stem cells. However, we still do not know how they go about. Experimental structure determination for such a system is very costly and time consuming. We aim to obtain one final model for the binding of Oct4 to the nucleosome by combining computer simulations with different lab experiments. Hopefully, our final model will give us the opportunity to engineer pioneer transcription factors for efficient and reliable production of stem cells and other cells needed in regenerative medicine.ReferenceHuertas et al.

Visualizing the Conversion of Adult Cells to Stem Cells - Technology Networks

Skin Stem Cells Comments Off on Visualizing the Conversion of Adult Cells to Stem Cells – Technology Networks | February 22nd, 2020

He asked her for a list of dream projects she would love to investigate. What followed was a year of challenges, stresses and the ultimate reward guided intellectual freedom toward scientific discovery.

Ashley Kramer, a student at the Wayne State University School of Medicine, is enrolled in the schools M.D.-Ph.D. program, an eight-year commitment broken down into three parts the first two years of medical school, four years of graduate school, then the final two years of medical school. Like all M.D./Ph.D. students at the medical school, Kramer had to complete research rotations with faculty she thought would make good dissertation advisors.

Because I have always loved stem cell biology and had experience working with zebrafish in the past, I decided to do an eight-week rotation in Dr. Thummels lab between my medical year one and medical year two, and made the decision that this was absolutely the perfect lab for me, she said.

Ryan Thummel, Ph.D., is an associate professor of Ophthalmology, Visual and Anatomical Sciences. His lab focuses on retinal development and regeneration in zebrafish, an attractive model to study neurodegenerative diseases because of its ability to regenerate neuronal tissues. Zebrafish fully regenerate their retinas in just a matter of weeks, an ability mammals lack.

Zebrafish and mammals both have a cell called Mller glia that supports retinal neurons. In zebrafish, however, these cells convert to stem cells and are responsible for retinal regeneration.

At the end of the rotation, Dr. Thummel floated the crazy idea of starting to work on this grant, a 70-plus page monster undertaking, during my M2 year, and I immediately jumped at the opportunity. I was excited at the idea of having a four-year research project completely planned out by the time I started my Ph.D. after M2 so I could hit the ground running after the dreaded STEP 1, Kramer said.

I came to him two days later with a nine-page document of project ideas. We sat down for three hours discussing projects and came up with a top-two list of cohesive projects for me to move forward with as a grant and thesis, she said. From there, it was a nearly yearlong process of writing, meeting, revising and repeating for each of the many sections of the grant.

The effort was worth it. Kramer secured a five-year, $294,102 grant from the National Eye Institute of the National Institutes of Health last year to study the molecular mechanisms of retinal regeneration in zebrafish, an organism that exhibits a remarkable capacity for regeneration.

"Ashley is a dedicated young scientist and worked very hard on this grant application," Dr. Thummel said.

The grant is one of the NIHs Ruth L. Kirschstein National Research Service awards, also known as an F30. The project, Elucidating the role of DNA methyltransferases in epigenetic regulation of retinal regeneration in the zebrafish, started last month. She is the principal investigator.

This was an incredibly challenging experience that allowed me to grow immensely as a scientist. Grant writing, planning effective and novel longitudinal scientific investigations, and time management will all be critical skills for me moving forward in my career as a physician scientist, she said. I cannot thank Dr. Thummel and my past advisors enough for all of their mentoring and support in the last ten years who have gotten me to where I am today, and I am looking forward to the rest of my training here at Wayne State and beyond.

Kramer earned her bachelors degree in Genetics, Cell Biology and Development from the University of Minnesota in 2014. Her love of research and stem cell biology started when she was an undergraduate research assistant there.

Nearly a decade later, she is studying how epigenetic marks are added to, and removed from, genes in zebrafish retinal stem cells during the process of retinal regeneration. The role of epigenetics in the body is akin to traffic signs on the road.

If roads had no traffic lights, stop signs or barricades, it would be complete chaos. The same is true for your cells. If you used every single gene encoded in your DNA 100% of the time, your cells would be chaos. Epigenetics is what is responsible for telling your skin cell to be a skin cell and your liver cell to be a liver cell, while they both have the exact same underlying DNA sequence, Kramer said. There are various different epigenetic marks that decorate the DNA without actually changing the sequence. These marks come in many forms and can act to either start, stop or change the amount that a particular gene is used, similar to how a green light, road block or stop sign direct traffic rules.

The process is critical for normal embryonic development and everyday cell processes.

If we can gain a deeper understanding of how species like the zebrafish are able to regenerate tissues when mammals cannot, despite having the same cell types, we may be able to start working to translate those mechanisms to mammals, she said. It is possible that certain regeneration pathways have been epigenetically silenced through evolution and we may be able to use modern advances in gene therapy techniques to unlock regenerative capacity in mammals.

Dubai: Myra, J, a belly dancer working at a Dubai hotel, was unhappy that saddle bags on her thighs were making her performance less graceful and she feared she would be replaced in her job. So on a weekend, she checked into a leading aesthetic clinic and the surgeon trimmed the pockets of fat around her thighs, sculpting her body back into perfect shape. It took her a week to recover and get back to work, but she is delighted with her shapely thighs and feels happier than ever before.

Nina M., (52), always loved how beautiful her eyes were and how youthful her cheeks looked. However last year, as she got busy with her sons marriage preparations, she started to experience bouts of anxiety at the sight of slowly encroaching bags under her eyes and a slight droop in her cheeks. I wanted to look and feel my best and thought a filler and a round of botox were harmless indulgences. It took me just an hour at the clinic and the results were amazing. I am glad I was able to stop the onslaught of aging in time. Its beautiful to age gracefully, but we all do use creams and gels to delay the process. I think of these minor injectibles as tools in our make-up bag. I have used fillers and Botox twice since last year, combined with my beauty regimen. I feel it has given me not just confidence but also psychological boost. I would recommend it to everyone.

Anna M was a physical trainer but vexed with her body shape as she had a masculine build. This was affecting her work as most women were intimidated by her personality and she was losing self-confidence. Four years ago, she went in for breast implants and her life changed. People talk about getting addicted to cosmetic surgery. But that is not so. Most people approach a cosmetic surgeon only when they cannot deal with a physical issue themselves and just like one needs medicine when one is ill, cosmetic surgery acts as a solution to boost confidence and self-esteem. Look at how people have reclaimed their health with gastric bypass!

- Dr Sanjay Parashar, chairman, Scientific of the Emirates Plastic Surgery Society

Changing the world one person at a time and providing them with an incredible burst of confidence, aesthetic and cosmetic surgeons in the UAE have built a practice of reliability that can take as little as one hour to a day to transform your personality. Welcome to the multi-million dirham cosmetic surgery industry in the UAE that is the toast of medical tourism in the region, With a high footfall of Gulf and Asian medical tourists as well as resident expatriates, the industry has accelerated at a speed that is making Dubai be hailed as the new Beverly Hills of the Middle East.

Cosmetic or Plastic Surgery?

These are two different concepts. Cosmetic surgery refers to aesthetic surgery and revolves around enhancement of physical features of an individual and is elective. This includes procedures such as rhinoplasty, face and cheek enhancement, brow lifts, neck and eyelid lift, face peels, laser resurfacing, botox fillers, peels, laser hair removal, breast augmentation, tummy tucks, liposuction, hair implants and dental veneers.

Plastic surgery, on the other hand, is a surgical speciality dealing with life-saving procedures of re-construction of the face and body owing to congenital defects, disfigurement due to accident, trauma, burns, tumour removal due to diseases such as cancer. In most cases, plastic surgery is not elective.

Dh12b Medical tourism sales in 2018

Since the time pop stars began to inundate Instagram with images of their perfect bodies, dazzling smiles, flawless skin and enviable hair volume, elective procedures have become commonplace with teenagers as young as 13 who are going in for instant fixes. While some procedures require a couple of days of hospital stay and being out of circulation for a while, many quick fixes are carried out during lunch breaks in one-hour durations.

Highest Per Capita cosmetic surgeons in UAE

Dr Sanjay Parashar, chairman, Scientific of the Emirates Plastic Surgery Society, told Gulf News: Cosmetic surgery tops the list in medical tourism in Dubai and according to a 2015 report of Dubai Health Authority (DHA), Dubai has the highest number of cosmetic surgeons per capita in the region - about 50 specialists for a million people.

- Dr Zuhair Al Fardan, President of the Emirates Plastic Surgery

Dr Parashar added: The field has grown beyond expectations and much of the credit goes to the development of a world-class infrastructure in this field and the corresponding health regulations. Today, in Dubai, most Day Care Surgery centres where most of the plastic surgery procedures are carried out have the best international accreditations.

Dr Zuhair Al Fardan, President of the Emirates Plastic Surgery, said,Much of the advancement in plastic and cosmetic surgery is work in progress as surgeons are constantly upgrading themselves with techniques, technologies. The UAE is keeping abreast of the best that is taking place in the world. In the last five years or so, there have been tremendous advancements in cosmetic and plastic surgery in the UAE. We have the top plastic surgeons of the world come here to do surgeries and the UAE hosts two major international plastic surgery conferences each year.

Soaring revenues

With greater acceptance and broadening of scope for the discipline, it is evident that plastic surgery is a major revenue earner and places UAE as one of the leading medical tourism destinations in the region. From a price range of Dh150-250 for a filler to Dh40,000 for a detailed body sculpting procedure, these procedures are money-spinners.

Together, the plastic and cosmetic surgery is a multimillion dirham business in the UAE. While there are no exact figures available, safe estimates can be made, say surgeons. Lets take the emirate of Dubai. There are 30 hospitals in Dubai, of which 70 per cent are internationally accredited. The emirate aims to build 22 hospitals by 2020 - 18 private and 4 public hospitals. At least 50 per cent of these offer cosmetic and plastic surgery options. Besides that there are about 150 Day Care Surgery centres and 400 aesthetic clinics in Dubai. All of them offer a bouquet of cosmetic surgery procedures and their average annual revenue is between Dh4-6 million a year. If one were to compute that with the numbers of facilities including hospitals, the annual revenue from cosmetic surgery would run into many millions of dirhams annually.

High on medical tourism

Currently, Dubai aims to attract 500,000 medical tourists a year by end 2020. In a short priod of time, Dubai has managed to be ranked 17 among the top 25 global destinations for medical tourism and cosmetic surgery, along with fertility, orthopaedic, dental and wellness disciplines in the list of most-billed medical procedures.

As per statistics, about 46 per cent of the current medical tourists in Dubai come from Asian countries, 25 per cent from GCC and Arab countries and 13 per cent from African countries, and the remaining 16 per cent from other countries, mainly the UK and Commonwealth of Independent States (CIS) countries. In fact, 40 per cent of tourists who come to Dubai come only for medical tourism.

- Dr Francis Conroy, consultant plastic, cosmetic and reconstructive surgeon at the American Hospital, Dubai

Medical tourism sales topped Dh12 billion in 2018, with a 5.5 per cent overall increase in medical tourists. Dubai attracted a total of 640,542 international and domestic medical tourists in 2018 (51 per cent were international patients). European tourists consisting mostly of UK, French and Italian citizens, share 16 per cent of health and wellness tourists. A substantial medical tourism revenue, it is evident, is earned through plastic and cosmetic surgery.

Dr Francis Conroy, consultant plastic, cosmetic and reconstructive surgeon at the American Hospital, Dubai, remarked: American Hospital Dubai, is one of the few facilities offering both comprehensive reconstructive and cosmetic surgery services. Our plastic surgeons are fully trained in both reconstructive and cosmetic surgery so we see a wide-ranging case mix, from severe trauma cases to cancer cases and of course, those opting for cosmetic surgery.

The most popular cosmetic surgery is body contouring namely abdominoplasty and liposuction, sometimes combined with a breast lift the mommy make-over. Typically, these patients would be female, who done with having children and raising them, now wish to address the changes in their body. I also see a large number of male patients who want to correct problems associated with their chest with the help of liposuction, said Dr Conroy.

Non-surgical treatments (neuro-modulators, fillers, etc) are still very popular and I have seen a trend in that patients are starting with such treatments at an earlier age.

Given the prestigious reputation of the hospital and the Dubai governments plan to promote medical tourism, I have noticed a huge influx of patients from Africa, Nigeria and Ghana in particular. These patients come mainly for cosmetic surgery, knowing that they are in the hands of a highly qualified surgeon, in a safe, luxurious facility, with standards second to none, said Dr Conroy.

Top six cosmetic surgery procedures in town

The procedures can be divided into categories:

Does health insurance cover plastic surgery?

Dr Parashar said: Lumps, bumps, nerve and tendon transfer, skin transplant, etc, are all covered. Few people know that plastic surgery has a regenerative and reconstructive role to play in case of congenital and disease deformities. Reconstructive surgery such as correction of birth deformities such as a tuberous breast, cleft lip, hand deformities, skin transplant following burns, road trauma and breast augmentation and reconstruction following a mastectomy and rebuilding after a tumour resection is all covered under all leading health insurances. There is also new kinds of stem cell therapy being used to regenerate tissues and nerves especially in diabetic patients.

Know the regulations:

The DHA has made it mandatory for all Day Care Surgery Centres, most of who carry out aesthetic procedures, to have one leading international accreditation from Canada, US, UK or Australia. These accreditations were earlier mandatory for hospitals only, but from 2020, all Day Care Surgery centres compulsorily must have an international accreditation. This ensures that an independent, international medical body enforces global health standards to grant them certification and in case of a sentinel event, conducts its independent inquiry and downgrades these places in case of a serious lapse. DHA on its own has issued a 25-page manual on quality and regulations that is to be followed at all centres.

A close examination of the Day Care Surgery centres indicates several layers of quality control.

Pre surgery quality: This involves free consultation, especially in case of a second opinion or a first time patient seeking to enquire about a procedure based on his/her requirement. When a patient uploads a request on the website of a centre from anywhere in the world, the centre has to provide a detailed consultation free of charge.

Services available to a patient: Once the patient is convinced and comes in person to consult the doctor, quality is upheld in the pre-diagnostic tests that the patient has to undergo.

Infrastructure quality: DHA has graded Day Care Centres into A, B and C categories based on the level of medical facilities that can be accessed by a patient. Anaesthesia methods such as oral, epidural and general also help classify centres. For instance, hair transplant procedures can only be carried out in B and above grade clinics. Day Care Centres that conduct surgeries under general anaesthesia much be equipped with the Advance Cardiac Life Support (ACLS) with their surgeons and registered nurses being certified as trained in administering ACLS to a patient.

Patient safety protocol: There are very specific guidelines for patient safety and the doctor/surgeon must explain the procedure in detail to the patient and his/her family and obtain a written consent to go ahead after ascertaining that all risks and side-effects have been clearly explained to the patient.

Post-operative regulation: There are specific protocols for discharge of patients undergoing cosmetic surgery. Although ambulatory care means the patient has to be discharged within the same day, there is a specification about asking the patient to desist from long-distance travel, specific rehabilitative work to be carried out from the next day for which the patient has to be within Dubai and also specific instructions when an overseas patient is declared fit to fly out of the country. When a patient flies out, he or she is provided with a proper review and notes, with instructions for overseas rehabilitation protocol with reference notes for the rehabilitation instructor and instructions for medication and periodic reviews.

Accountability

The law is clear, said Dr Al Fardan, The DHA regulations constitutes an accountability committee and holds an enquiry to fix the liability. If the centre is found guilty, its licence can be suspended or cancelled depending on the extent of guilt. If the surgeon, anaesthesiologists, nurse and technicians are found guilty, their license to practice is suspended or cancelled. If the crime is lighter, then both the centre and the team are let off with serious warnings. In case of disability following a surgery, the team examines the extent of disability and calculates the financial compensation to the patient. In case of fatality following a surgery, the is provision to pay blood money.

The global Collagen and gelatin market for regenerative medicine will grow at a CAGR of 8.5% from 2017 to 2022 to reach USD 709.9 million by 2022, according to the latest publication from Meticulous Research. The global collagen and gelatin market for regenerative medicine is driven by rising prevalence of chronic diseases, rapid growth in aging population, and increasing funding for R&D of regenerative medicines. However, growing use of alternate biomaterials inhibits the growth of this market to some extent.

The global collagen and gelatin market for regenerative medicine is mainly segmented by type (collagen and gelatin), by source (porcine, bovine, marine, and other), by application (orthopedics, cardiovascular, wound care, and other), and geography. Based on source, bovine collagen and gelatin held the largest share of the market in 2016, owing to their abundant availability and wide range of applications in the tendon reinforcement, hernia repair, skin & wound healing, and plastic & reconstructive surgery. Further, on the basis of application, orthopedics accounted for the major share of the global collagen and gelatin market for regenerative medicines in 2016, owing to the high prevalence of osteoporosis across the globe due to aging population, growing obesity, and a poor level of physical activity.

A case of reverse development: Dana-Farber scientists solve long-debated puzzle of how the intestine heals itself

Newswise BOSTON Deep within the lining of the human intestine lies the source of the organs ability to renew itself and recover from damage: intestinal stem cells (ISCs), lodged in pockets of tissue called crypts, generate the cells that continuously repopulate the intestinal lining. Even the stem cells themselves have a safety net: when theyre damaged, healthy replacements appear in less than a week.

For years, scientists have debated how the ISCs re-emergence occurs. Some have held that the intestine keeps a pool of ISCs on reserve a kind of backup-backup supply to replenish the cache of front-line ISCs that have been lost. Others have maintained that something more involuted is as work: The ISCs, like queen bees, give rise to more specialized, or differentiated, progeny in this case, daughter cells that form the inner lining of the intestine. When the ISCs are damaged, this school of thought held, the daughter cells reverse course and de-differentiate reverting into the ISCs from which they arose.

A new study by Dana-Farber Cancer Institute scientists comes down solidly on the latter option.

Published online today by the journalCell Stem Cell, the researchers found that ISCs and their daughter cells have a strikingly reciprocal relationship: under normal conditions, ISCs differentiate into daughter cells, and, if the ISCs are lost, the daughter cells simply reverse course and become ISCs. Our findings suggest that the restoration of intestinal stem cells occurs entirely by the process of de-differentiation, says the studys senior author, Ramesh Shivdasani, MD, PhD, of Dana-Farber, Brigham and Womens Hospital (BWH), and the Harvard Stem Cell Institute. We showed theres no need for a reserve set of ISCs.

Bolstering their findings, the researchers were also able to capture the de-differentiation process in real time. When cells begin to de-differentiate, they switch on a gene that that allows them to be isolated and collected with laboratory techniques, Shivdasani explains. Through this process, researchers were able to capture the cells along a continuum of de-differentiation. Shivdasani likens it to a baseball play in which a runner is tagged out between first and second base.

Heavy turnover

The intestine is one of just three tissues in the body, along with the skin and blood, in which cells are constantly turning over dying and being replaced by freshly made cells. They share this quality because they are the tissues most intimately in contact with material from the environment, and therefore with potentially harmful substances. The constant turnover, its thought, is a way to prevent toxic substances from having lasting effects on cells and their offspring.

The crypts that hold ISCs are, in a sense, misnamed. Far from being enclosures where dead cells are entombed, they are the sites where ISCs daily generate the billions of daughter cells that take the place of defunct intestinal cells.

One of the chief characteristics of ISCs is that they are extremely radiosensitive, or vulnerable to radiation. People exposed to high levels of radioactivity, in the form of nuclear fallout, for example, can suffer severe intestinal damage because the loss of ISCs halts production of cells to regenerate the damaged tissue. But if ISCs succumb easily to radiation, they also make a rapid return. Patients with radiation-induced intestinal damage who can be kept alive for a week often recover as their ISC levels bounce back.

To determine whether this rebound is due to a reserve stockpile of ISCs or to de-differentiation of daughter cells, Shivdasani and his collaborators performed a kind of time-lapse experiment. They treated a collection of ISC cells with the drug tamoxifen, which caused the cells and their offspring to become fluorescent. They waited 48 hours for the label to take hold, then killed the ISC cells. If the daughter cells were indeed de-differentiating, any ISC cells produced after that point would be fluorescent.Thats exactly what researchers found.

While scientists have been able to convert many kinds of differentiated cells into stem cells using laboratory techniques, Shivdasani and his colleagues discovery demonstrates that de-differentiation ismore than a curious act of nature; it is the principal means to restore damaged stem cell in the intestine. Its not known whether cells in other organs and tissues have this capability, but it remains an open avenue of investigation.

It also isnt clear how the crypt knows that stem cells have died and need to be replaced, Shivdasani remarks, or how the daughter cells receive the signal to de-differentiate. This is a subject were currently exploring.

(BPT) - For many people with cancer and other life-threatening diseases, stem cell transplants provide hope and can impact the course of the disease, but they also come with risks. One of those risks is graftversushost disease (GVHD).

What is GVHD?

GVHD is a potentially life-threatening condition that can occur after an allogeneic stem cell transplant from a donor, in which the donated cells initiate an immune response and attack the recipient's organs and tissues. There are two major forms of GVHD, acute and chronic, that can affect multiple organ systems including the skin, gastrointestinal (digestive) tract and liver.

Although the exact incidence of GVHD is unknown, it is estimated that up to 70% of stem cell transplant recipients will develop either acute or chronic GVHD, resulting in significant morbidity and mortality. Due to these concerning statistics, health care experts and the entire GVHD community are calling for additional research and support.

People with GVHD and their caregivers face a multitude of challenges, often including limited support, minimal information and few treatment options. Its time to change the future for those living with GVHD.

New award inspires the GVHD community

The Incyte Ingenuity Award aims to encourage innovation in GVHD care and other serious diseases. As part of the award, one unique proposal that addresses a critical unmet need in the GVHD community will be awarded up to $100,000 for the proposed initiative to be developed and executed. Specific initiatives may include patient and/or professional educational programs, policy-focused activities as well as awareness and support campaigns.

Incyte wanted to create a community driven program dedicated to improving the lives of patients with serious diseases, such as GVHD, which can be difficult to treat and have a devastating impact on the lives of patients, says Barry Flannelly, Pharm.D., Executive Vice President and General Manager, U.S., Incyte. Through this award, we hope to spark creativity and innovation, resulting in impactful and actionable initiatives for the GVHD community.

Skin Stem Cells Comments Off on Health insights: What is GVHD and why is innovation so critical? – Eagle & Times | February 21st, 2020

The road into Batlow is littered with the dead.

In the smoky, gray haze of the morning, it's hard to make out exactly what Matt Roberts' camera is capturing. Roberts, a photojournalist with the Australian Broadcasting Corporation, keeps his lens focused on the road as he rolls into the fire-ravaged town 55 miles west of Canberra, Australia's capital. At the asphalt's edge, blackened livestock carcasses lie motionless.

The grim scene, widely shared on social media, is emblematic of the impact the 2019-20 bushfire season has had on Australia's animal life. Some estimates suggest "many, many billions" of animals have been killed, populations of endemic insects could be crippled and, as ash washes into riverways, marine life will be severely impacted. The scale of the bushfires is so massive, scientists are unlikely to know the impact on wildlife for many years.

But even before bushfires roared across the country, Australia's unique native animals were in a dire fight for survival. Habitat destruction, invasive species, hunting and climate change have conspired against them. Populations of native fauna are plummeting or disappearing altogether, leaving Australia with an unenviable record: It has the highest rate of mammal extinctions in the world.

A large share of Australia's extinctions have involved marsupials -- the class of mammals that includes the nation's iconic kangaroos, wallabies, koalas and wombats. A century ago, the Tasmanian tiger still padded quietly through Australia's forests. The desert rat-kangaroo hopped across the clay pans of the outback, sheltering from the sun in dug-out nests.

Now they're gone.

Australia's 2019-20 bushfire season has been devastating for wildlife.

In a search for answers to the extinction crisis, researchers are turning to one lesser-known species, small enough to fit in the palm of your hand: the fat-tailed dunnart. The carnivorous mouse-like marsupial, no bigger than a golf ball and about as heavy as a toothbrush, has a tiny snout, dark, bulbous eyes and, unsurprisingly, a fat tail. It's Baby Yoda levels of adorable -- and it may be just as influential.

Mapping the dunnart's genome could help this little animal become the marsupial equivalent of the lab mouse -- a model organism scientists use to better understand biological processes, manipulate genes and test new approaches to treating disease. The ambitious project, driven by marsupial geneticist Andrew Pask and his team at the University of Melbourne over the last two years, will see scientists take advantage of incredible feats of genetic engineering, reprogramming cells at will.

It could even aid the creation of a frozen Noah's Ark of samples: a doomsday vault of marsupial cells, suspended in time, to preserve genetic diversity and help prevent further decline, bringing species back from the brink of extinction.

If that sounds far-fetched, it isn't. In fact, it's already happening.

Creating a reliable marsupial model organism is a long-held dream for Australian geneticists, stretching back to research pioneered by famed statistician Ronald Fisher in the mid-20th century. To understand why the model is so important, we need to look at the lab mouse, a staple of science laboratories for centuries.

"A lot of what we know about how genes work, and how genes work with each other, comes from the mouse," says Jenny Graves, a geneticist at La Trobe University in Victoria, Australia, who has worked with marsupials for five decades.

The mouse is an indispensable model organism that shares many genetic similarities with humans. It has been key in understanding basic human biology, testing new medicines and unraveling the mysteries of how our brains work. Mice form such a critical part of the scientific endeavor because they breed quickly, have large litters, and are cheap to house, feed and maintain.

The lab mouse has been indispensable in understanding physiology, biology and genetics.

In the 1970s, scientists developed a method to insert new genes into mice. After a decade of refinement, these genetically modified mice (known as "transgenic mice") provided novel ways to study how genes function. You could add a gene, turning its expression up to 11, or delete a gene entirely, shutting it off. Scientists had a powerful tool to discover which genes performed the critical work in reproduction, development and maturation.

The same capability does not exist for marsupials. "At the moment, we don't have any way of manipulating genes in a devil or a kangaroo or a possum," says Graves. Without this capability, it's difficult to answer more pointed questions about marsupial genes and how they compare with mammal genes, like those of mice and humans.

So far, two marsupial species -- the Tammar wallaby and the American opossum -- have been front and center of research efforts to create a reliable model organism, but they both pose problems. The wallaby breeds slowly, with only one baby every 18 months, and it requires vast swaths of land to maintain.

The short-tailed opossum might prove an even more complicated case. Pask, the marsupial geneticist, says the small South American marsupial is prone to eating its young, and breeding requires researchers to sift through hours of video footage, looking for who impregnated whom. Pask also makes a patriotic jab ("they're American so we don't like them") and says their differences from Australian marsupials make them less useful for the problems Australian species face.

But the dunnart boasts all the features that make the mouse such an attractive organism for study: It is small and easy to house, breeds well in captivity and has large litters.

"Our little guys are just like having a mouse basically, except they have a pouch," Pask says.

Pask (front) and Frankenberg inspect some of their dunnarts at the University of Melbourne.

A stern warning precedes my first meeting with Pask's colony of fat-tailed dunnarts.

"It smells like shit," he says. "They shit everywhere."

I quickly discover he's right. Upon entering the colony's dwellings on the third floor of the University of Melbourne's utilitarian BioSciences building, you're punched in the face by a musty, fecal smell.

Pask, a laid-back researcher whose face is almost permanently fixed with a smile, and one of his colleagues, researcher Stephen Frankenberg, appear unfazed by the odor. They've adapted to it. Inside the small room that houses the colony, storage-box-cages are stacked three shelves high. They're filled with upturned egg cartons and empty buckets, which work as makeshift nests for the critters to hide in.

Andrew Pask

Frankenberg reaches in without hesitation and plucks one from a cage -- nameless but numbered "29" -- and it hides in his enclosed fist before peeking out of the gap between his thumb and forefinger, snout pulsing. As I watch Frankenberg cradle it, the dunnart seems curious, and Pask warns me it's more than agile enough to manufacture a great escape.

In the wild, fat-tailed dunnarts are just as inquisitive and fleet-footed. Their range extends across most of southern and central Australia, and the most recent assessment of their population numbers shows they aren't suffering population declines in the same way many of Australia's bigger marsupial species are.

Move over, Baby Yoda.

As I watch 29 scamper up Frankenberg's arm, the physical similarities between it and a mouse are obvious. Pask explains that the dunnart's DNA is much more closely related to the Tasmanian devil, an endangered cat-sized carnivore native to Australia, than the mouse. But from a research perspective, Pask notes the similarities between mouse and dunnart run deep -- and that's why it's such an important critter.

"The dunnart is going to be our marsupial workhorse like the mouse is for placental mammals," Pask says.

For that to happen, Pask's team has to perfect an incredible feat of genetic engineering: They have to learn how to reprogram its cells.

To do so, they collect skin cells from the dunnart's ear or footpad and drop them in a flask where scientists can introduce new genes into the skin cell. The introduced genes are able to trick the adult cell, convincing it to become a "younger," specialized cell with almost unlimited potential.

The reprogrammed cells are known as "induced pluripotent stem cells," or iPS cells, and since Japanese scientists unraveled how to perform this incredible feat in 2006, they have proven to be indispensable for researchers because they can become any cell in the body.

"You can grow them in culture and put different sorts of differentiation factors on them and see if they can turn into nerve cells, muscle cells, brain cells, blood vessels," Pask explains. That means these special cells could even be programmed to become a sperm or an egg, in turn allowing embryos to be made.

Implanting the embryo in a surrogate mother could create a whole animal.

It took about 15 minutes to get this dunnart to sit still.

Although such a technological leap has been made in mice, it's still a long way from fruition for marsupials. At present, only the Tasmanian devil has had iPS cells created from skin, and no sperm or egg cells were produced.

Pask's team has been able to dupe the dunnart's cells into reverting to stem cells -- and they've even made some slight genetic tweaks in the lab. But that's just the first step.

He believes there are likely to be small differences between species, but if the methodology remains consistent and reproducible in other marsupials, scientists could begin to create iPS cells from Australia's array of unique fauna. They could even sample skin cells from wild marsupials and reprogram those.

Doing so would be indispensable in the creation of a biobank, where the cells would be frozen down to -196 degrees Celsius (-273F) and stored until they're needed. It would act as a safeguard -- a backup copy of genetic material that could, in some distant future, be used to bring species back from the edge of oblivion, helping repopulate them and restoring their genetic diversity.

Underneath San Diego Zoo's Beckman Center for Conservation Research lies the Frozen Zoo, a repository of test tubes containing the genetic material of over 10,000 species. Stacked in towers and chilled inside giant metal vats, the tubes contain the DNA of threatened species from around the world, suspended in time.

It's the largest wildlife biobank in the world.

"Our goal is to opportunistically collect cells ... on multiple individuals of as many species as we can, to provide a vast genetic resource for research and conservation efforts," explains Marlys Houck, curator at the Frozen Zoo.

The Zoo's efforts to save the northern white rhino from extinction have been well publicized. Other research groups have been able to create a northern white rhino embryo in the lab, combining eggs of the last two remaining females with frozen sperm from departed males. Scientists propose implanting those embryos in a surrogate mother of a closely related species, the southern white rhino, to help drag the species back from the edge of oblivion.

For the better part of a decade, conservationists have been focused on this goal, and now their work is paying off: In the "coming months," the lab-created northern white rhino embryo will be implanted in a surrogate.

Sudan, the last male northern white rhinoceros, was euthanized in 2018.

Marisa Korody, a conservation geneticist at the Frozen Zoo, stresses that this type of intervention was really the last hope for the rhino, a species whose population had already diminished to just eight individuals a decade ago.

"We only turn to these methods when more traditional conservation methods have failed," she says.

In Australia, researchers are telling whoever will listen that traditional conservation methods are failing.

"We've been saying for decades and decades, many of our species are on a slippery slope," says John Rodger, a marsupial conservationist at the University of Newcastle, Australia, and CEO of the Fauna Research Alliance, which has long advocated for the banking of genetic material of species in Australia and New Zealand.

In October, 240 of Australia's top scientists delivered a letter to the government detailing the country's woeful record on protecting species, citing the 1,800 plants and animals in danger of extinction, and the "weak" environmental laws which have been ineffective at keeping Australian fauna alive.

Institutions around Australia, such as Taronga Zoo and Monash University, have been biobanking samples since the '90s, reliant on philanthropic donations to stay online, but researchers say this is not enough. For at least a decade, they've been calling for the establishment of a national biobank to support Australia's threatened species.

John Rodger

"Our real problem in Australia ... is underinvestment," Rodger says. "You've got to accept this is not a short-term investment."

The current government installed a threatened-species commissioner in 2017 and committed $255 million ($171 million in US dollars) in funding to improve the prospects of 20 mammal species by 2020. In the most recent progress report, released in 2019, only eight of those 20 were identified as having an "improved trajectory," meaning populations were either increasing faster or declining slower compared to 2015.

A spokesperson for the commissioner outlined the $50 million investment to support immediate work to protect wildlife following the bushfires, speaking to monitoring programs, establishment of "insurance populations" and feral cat traps. No future strategies regarding biobanking were referenced.

Researchers believe we need to act now to preserve iconic Australian species like the koala.

In the wake of the catastrophic bushfire season and the challenges posed by climate change, Australia's extinction crisis is again in the spotlight. Koalas are plastered over social media with charred noses and bandaged skin. On the front page of newspapers, kangaroos bound in front of towering walls of flame.

Houck notes that San Diego's Frozen Zoo currently stores cell lines "from nearly 30 marsupial species, including koala, Tasmanian devil and kangaroo," but that's only one-tenth of the known marsupial species living in Australia today.

"Nobody in the world is seriously working on marsupials but us," Rodger says. "We've got a huge interest in maintaining these guys for tourism, national icons... you name it."

There's a creeping sense of dread in the researchers I talk to that perhaps we've passed a tipping point, not just in Australia, but across the world. "We are losing species at an alarming rate," says Korody from the Frozen Zoo. "Some species are going extinct before we even know they are there."

With such high stakes, Pask and his dunnarts are in a race against time. Perfecting the techniques to genetically engineer the tiny marsupial's cells will help enable the preservation of all marsupial species for generations to come, future-proofing them against natural disasters, disease, land-clearing and threats we may not even be able to predict right now.

Pask reasons "we owe it" to marsupials to develop these tools and, at the very least, biobank their cells if we can't prevent extinction. "We really should be investing in this stuff now," he says. He's optimistic.

In some distant future, years from now, a bundle of frozen stem cells might just bring the koala or the kangaroo back from the brink of extinction.

And for that, we'll have the dunnart to thank.
