Logan Van Dyk hopes stem cell operation in Central America will open doors for him ones that shut abruptly on Aug. 3, 2008.

It took seconds for the now 26-year-old Fort Langley residents life to change.

On that day nearly nine years ago, just after he graduated from R.E. Mountain Secondary, Van Dyk suffered a life-altering spinal cord injury in a mountain biking incident.

I was fooling around on a construction site with some friends and I accidentally fell off a dirt pile on my bike, recalled Van Dyk, who was born and raised in Langley. I fell 25 feet and landed on my face.

Van Dyk suffered a spinal cord injury that left him bound to a wheelchair, as a partial quadriplegic.

I got a C56 spinal cord injury, but its incomplete which means theres always a possibility for recovery, Van Dyk said.

Its that hope that has Van Dyk looking to travel to Panama for therapy.

He started doing some research on stem cells and found an institute in Panama City that offers treatments.

Van Dyk sent in an application and on March 8 received an email saying he will make an excellent candidate for stem cell therapy.

Of course there is no guarantee that I will gain anything back but at this point Im willing to try anything to improve the quality of my life, said Van Dyk, who hopes to get into broadcasting.

He has created a GoFundMe page to raise what he believes is the $45,000 necessary to pay for flights, treatments, accommodations, and a personal nurse in Panama City. Visit http://www.gofundme.com/anw8ce-stem-cell-research.

The therapy itself will cost roughly $37,400 US. As well, there are no nurses at the institute who would assist Van Dyk directly.

I receive care twice a day in order to get in and out of my wheelchair and in and out of bed, Van Dyke explained. So I need to get a bit of extra money so I can hire a nurse to come down with me. Im not sure how much that is going to cost.

A friend who works as a nurse guided Van Dyk towards the possibility of travelling to Panama.

She couldnt believe there was nothing that could be done given the circumstances of my injury, Van Dyke said, because Ive got feeling all the way down to my toes. She looked into it and she found this down in Panama City. We looked at it and found some testimonials from some people who have gone down. They say they have about a 75 per cent success rate.

Van Dyk said he always does his best to remain positive and happy in everything he does.

Even the most basic of things take all my effort to achieve, Van Dyk said on his GoFundMe page. There just had to be something out there that could make things easier.

However, time is running out.

Unfortunately, the cutoff is 10 years, Van Dyk said. They wont do this treatment on anybody whose injury is over 10 years old. Im at my deadline.

Positive attitude

After the accident, Van Dyk was told by doctors that it was very unlikely he would ever walk again and would need to be in a power wheelchair for the rest of his life.

Van Dyk said much to their surprise, he wasnt able to accept that and he worked as hard as possible to overcome the barriers the medical world presented him with, and within a few months started using a manual wheelchair every day.

Mobility however, did not return and life has been a constant struggle ever since.

Keeping Van Dyk moving forward has been a positive attitude, and he quickly adapted to his new life in a wheelchair. It was pretty easy to get over it. I never had trouble finding the positives in life. I kind of adapted. A lot of people would say that I am the most positive person that theyve ever met. I get compliments a lot on how well I actually dealt with the injury. It was difficult but it was easy at the same time.

Van Dyk is now turning to the public to help him regain some freedom.

I miss the active lifestyle I led prior to injury, and am getting really tired of sitting all day long with a limited amount of things I can do to entertain myself, Van Dyk said. Im as independent as a I can be and I still rely on a lot of help. If I can get anything back, even just a bit more upper body Im just looking for anything at this point.

Purpose: Alkali-treated titanium with nanonetwork structures (TNS) possesses good osteogenic activity; however, the resistance of this material to bacterial contamination remains inadequate. As such, TNS implants are prone to postoperative infection. In this work, we attempted to alter the biological properties of TNS by treatment with short-duration high-intensity ultraviolet (UV) irradiation. Methods: TNS discs were treated with UV light (wavelength =254 nm, strength =100 mW/cm2) for 15 minutes using a UV-irradiation machine. We carried out a surface characterization and evaluated the discs for bacterial film formation, protein adsorption, and osteogenic features. Results: The superhydrophilicity and surface hydrocarbon elimination exhibited by the treated material (UV-treated titanium with a nanonetwork structure [UV-TNS]) revealed that this treatment effectively changed the surface characteristics of TNS. Notably, UV-TNS also showed reduced colonization by Actinomyces oris during an initial attachment period and inhibition of biofilm formation for up to 6 hours. Moreover, compared to conventional TNS, UV-TNS showed superior osteogenic activity as indicated by increased levels of adhesion, proliferation, alkaline phosphatase activity, osteogenic factor production, and osteogenesis-related gene expression by rat bone marrow mesenchymal stem cells (rBMMSCs). This inverse relationship between bacterial attachment and cell adhesion could be due to the presence of electronhole pairs induced by high-intensity UV treatment. Conclusion: We suggest that simple UV treatment has great clinical potential for TNS implants, as it promotes the osseointegration of the TNS while reducing bacterial contamination, and can be conducted chair-side immediately prior to implantation.

A Winnipeg toddlerwith acute myeloid leukemia has died after hundreds came forward to register as donors in an effort to help him.

After being diagnosed with the disease on Oct. 25, 20-month-old Tegveer Minhaswent through two rounds of chemotherapy, losing his hair and a lot of weight.

During that time, his family put out calls to the public to come forward and register bone marrow and stem cell information, in hopes that someone would be a match.

Hundreds of people in Manitoba, Ontario and Alberta were swabbed, and Tegveer got a stem cell donation, but his dad said it didn't work.

"After eight months of struggle, he passed away on June 18, early in the morning at 6 a.m.," said his dad,Sukhbir Minhas.

Minhas saidhis family is trying to stay strong, but they are having a hard time.

"He was a happy soul. He loved to go out. We took him to Clear Lake on June 4, and I wish I knew that he would love it so much. We were planning to go back again," Minhas said.

The hundreds of strangers who registered as donors, prayed for and even phoned the family to offer supportmeant the world to Minhas and his wife, he said.

"There was a time in the hospital, it was in January I think, we were so sure that my son's going to be all right, because it's just not me and my wife, it's thousands of other people who are praying for him," he said.

He urged people, especially young people aged 18 to 35, to register as donors to help other families.

"I respect every person from the bottom of my heart who went and got themselves swabbed, and even those who just had a thought of going and get themselves swabbed. That means they care for my son as I and my wife," he said.

"It feels a little better than if there was nobody for us."

Richard Sennott, Star Tribune file During a family portrait in 2000, Molly Nash gives her 4-week-old brother, Adam, a kiss. Molly Nash received some umbilical blood from her brother, saving her from a fatal genetic disease.

Adam Nash was dubbed Little Frankenstein by the New York Post in 2000 because he was conceived via in vitro fertilization specifically so doctors at the University of Minnesota could collect stem cells from his umbilical cord blood to save his sister, Molly.

Today, back home in Colorado, Adam has a drivers license and helps disabled children ski. His sister once weeks from death due to a condition called Fanconi anemia is debating whether to focus on oceanography or graphic design in college. And IVF to produce an ideal child for a siblings stem cell transplant is common, albeit with lingering ethics concerns.

A squirrelly trio of teens is vindication for Adams mother, Lisa Nash, who felt the weight of the ethical questions when the Us Dr. John Wagner suggested IVF in 1995.

Fiona Geekie, a nurse practitioner for TheCentral London Community Healthcare NHS Trust, donated bone marrow to a person she had never met earlier this year.

According to Fiona, about 2,000 people in the UK require a bone marrow or stem cell transplant every year.

For most of them its their last chance of surviving blood cancer, she added.

The nurse, who is a member of the Merton enhanced rapid intervention team,described why she went on the register to donate through the Anthony Nolan Trust 15 years ago.

Three quarters cant find a matching donor in their family so rely upon the generosity of a complete stranger already on the bone marrow register. So I joined up, it was simple.

Last Christmas Fiona was called for blood tests as she was a possible match for someone.

I was surprised to be called in the first place and I must confess I was a little apprehensive, Fiona admitted.

However, she continued: But then I thought what if someone in my family needed a bone marrow transplant. Its the most fantastic gift you can give to total stranger.

After donating, Fiona said she felt quite emotional and wanted the recipient to get well again.

She concluded: Overall, it was a wonderful experience and I have no hesitation in recommending all young people aged 16-30 to consider joining the bone marrow donor register.

Researchers from Singapore have developed a 3D tissue model than can be used to test drugs for their effects on the heart in a more realistic manner.

Asian Scientist Newsroom | June 22, 2017 | In the Lab

AsianScientist (Jun. 22, 2017) - Researchers at the Institute of Bioengineering and Nanotechnology (IBN) of the Agency for Science, Technology and Research (A*STAR) have engineered a three-dimensional heart tissue from human stem cells to test the safety and efficacy of new drugs on the heart. Their research has been published in Biofabrication.

Cardiotoxicity, which can lead to heart failure and even death, is a major cause of drug withdrawal from the market. So it is important to test as early as possible whether a newly developed drug is safe for human use. However, cardiotoxicity is difficult to predict in the early stages of drug development, said Professor Jackie Y. Ying, Executive Director at IBN.

A big part of the problem is the use of animals or animal-derived cells in preclinical cardiotoxicity studies due to the limited availability of human heart muscle cells. Substantial genetic and cardiac differences exist between animals and humans. There have been a large number of cases whereby the tests failed to detect cardiovascular toxicity when moving from animal studies to human clinical trials.

Existing screening methods based on 2D cardiac structure cannot accurately predict drug toxicity, while the currently available 3D structures for screening are difficult to fabricate in the quantities needed for commercial application.

To solve this problem, the IBN research team fabricated their 3D heart tissue from cellular self-assembly of heart muscle cells grown from human induced pluripotent stem cells. They also developed a fluorescence labelling technology to monitor changes in beating rate using a real-time video recording system.

The new heart tissue exhibited more cardiac-specific genes, stronger contraction and higher beating rate compared to cells in a 2D structure.

Using the 3D heart tissue, we were able to correctly predict cardiotoxic effects based on changes in the beating rate, even when these were not detected by conventional tests. The method is simple and suitable for large-scale assessment of drug side effects. It could also be used to design personalized therapy using a patients own cells, said lead researcher Dr. Andrew Wan, who is Team Leader and Principal Research Scientist at IBN.

The researchers have filed a patent on their human heart tissue model, and hope to work with clinicians and pharmaceutical companies to bring this technology to market.

Dr. Keith Roach, Syndicated Columnist

DEAR DR. ROACH: I hope you can answer some questions about myelodysplastic syndrome. What does it do to your body? Is there a known cause or cure? What is the prognosis? P.B. ANSWER: The myelodysplastic syndromes are a group of similar diseases, specific types of blood cancers, that prevent your bone marrow from working properly. They also can transform into acute leukemia. These are uncommon cancers, with perhaps 30,000 cases per year in the U.S. The specific myelodysplastic syndromes are now categorized by appearance, genetic abnormalities of the cells, and condition of the bone marrow.

MDS may arise from damage to DNA, such as from radiation or other toxic exposures. However, many cases have no known cause, and its likely that these are spontaneous mutations in the bone marrow cells.

Because MDS is a group of related diseases, the treatment and prognosis vary among the different subtypes. However, supporting the bone marrow with transfusions of red blood cells and platelets often is necessary. Medications to stimulate both red and white blood cell production can be used. A few people will be recommended for bone marrow (stem cell) transplant, but the decision to consider this treatment must be made cautiously, as many people who get MDS will not benefit from this treatment due to age or other medical conditions.

The prognosis depends on the age of the person affected and their specific MDS. A person younger than 60 with a low-risk MDS has a median survival (based on data published in 1997) of about 12 years. However, high-risk MDS has a much worse outcome: Half of people succumb within six months. Advances in treatment since these data were published have improved these results, but not as much as hoped.

DEAR DR. ROACH: My 89-year-old mother suffers from fluttering in her heart. She saw an expert in cardiac arrhythmias, who diagnosed her with tachy-brady syndrome and sick sinus syndrome. A nurse also said she has PVCs. She is taking metoprolol, but still has episodes of fluttering. What are these conditions? Are there other medications she could take to correct this heart condition? M.D.P.

ANSWER: Tachy-brady syndrome (from the Greek roots for fast and slow) and sick sinus syndrome are the same thing. The sinus in sick sinus syndrome refers to the sino-atrial node of the heart, which is the hearts natural pacemaker. It is where every beat normally starts. This part of the heart can become diseased, and the heart can beat both too quickly (tachycardia) and, at other times, too slowly (bradycardia). Sick sinus syndrome can come from many different conditions and, rarely, from medications.

Medications are sometimes used for sick sinus syndrome. Beta blockers, like the metoprolol your mother is taking, are given to slow down the tachycardic component of sick sinus, but it can make the bradycardia worse. Most often, the treatment for sick sinus syndrome is a permanent pacemaker. Not everyone needs it, but Im sure your mothers cardiologist is monitoring her and will recommend a pacemaker if needed. If one is necessary, 89 years old is not too old to put in a pacemaker.

PVCs are very common and do not usually indicate disease in the heart, although they are more common in people with heart disease, especially poor blood flow to the heart. Premature ventricular contractions themselves seldom need treatment.

El Grecos Resurrection

A rabbi has issued a warning after concluding that raising the dead is clearly possible.

Its not for man to do.

The comments come from Rabbi Moshe Avraham Halperin and were reported by Breaking Israel News.

If they are able to revive a person from total brain death, it will be considered techiyat hamaytim [resurrection], he told BIN. Torah laws puts limits on man, forbidding him from some areas which are strictly divine. Reviving the dead is one of them.

Further, another rabbi said such experiments never will succeed.

The Rambam states that we must believe that the resurrection of the dead will happen when it is Gods will for it to take place and at no other time, Rabbi Yosef Berger, of King Davids Tom on Mount Zion in Jerusalem, told the news agency.

Transhumanism: Recreating humanity reveals the secret ways scientists are using technologyto pursue immortality, omniscience and ultimate power. Now available in the WND Superstore.

He was citing the 13 Principles of Faith set down by Rabbi Moses ben Maimon, whose 12th century work established him as a Torah authority and gave him the acronym Rambam.

He stated, I believe by complete faith that there will be a resurrection of the dead at the time that will be pleasing before the Creator.

That, Berger suggested, means, Not only does this effort by scientists go against this principle of faith, but we know that true resurrection can only happen by Divine will. Resurrection of the dead is described in depth, and it is proof of Gods rule over the physical world. But it is also stated that before the Messiah, there is no return from the grave.

The comments come on the heels of plans by a biomedical company, Bioquark, a startup based in Pennsylvania, to experiment with stem cells in an attempt to revive brain-dead patients.

BIN reported the company said it would launch experiments before the end of the year on such patients.

The trial will involve a multi-pronged approach, involving injecting stem cells and peptides into the spinal cords, electrical nerve stimulation, and laser therapy. The researchers hope this will grow new neurons and spur them to connect to each other, bringing the brain back to life, BIN reported.

The story pointed out that Bioquark reportedly tried such an experiment in India in 2016 but it was not with the approval of the nations drug regulators.

Amar Jesani, editor of the Indian Journal of Medical Ethics in Mumbai, cautioned that even partial success would traumatize families that had come to terms with a situation they believed irreversible. In point of fact, no families permitted their loved ones to be part of the experiment, BIN reported.

Halperin said, This is like using genetics to create a new form of life. There are realms that are strictly divine. Resurrection of the dead is clearly possible. It is definitely going to happen after the Messiah, but it restricted to God.

It was reported about a year ago that Bioquark and another company were embarking on the Reanima project, using a new drug formula involving stem cells.

Their plan was to use neurons, proteins, peptides and more that would create a microenvironment in which the stems cells can mature.

The report said, Inspired by organisms like salamanders that can regrow severed or damaged tails, Bioquark researchers have been developing regenerative treatments for a host of uses, from cancer to spinal cord injuries.

WND had reported when the company was given the green light on the visionary project.

The company said then it was capable of creating dynamics in mature tissues that are normally only seen during human fetal development, as well as during limb and organ regeneration in organisms like amphibians.

Christian author and filmmaker Tom Horn, at that time, said scientists are redefining what it means to be human, with the goal of transcending humanity.

Right here in North Carolina at your university, they have what is called a transgenic lab, which means they have mice that have human genetic material, for testing to see if the human parts in that animal are responding, he told TV host Sid Roth in a recent interview.

Using a gene-editing technique, one university lab cured cancer in a group of rats, but the unintended consequences were that the rats started aging very quickly and died at half-life, and nobody knows why that happened, Horn said. There is a danger in playing God because youre not God and you dont know.

BURR RIDGE, Ill., June 13, 2017 /PRNewswire/ -- Dr. Win L. Chiou, a world-renowned authority in pharmacokinetics, an expert in dermatology and a former FDA consultant, has recently published a commentary questioning some widely accepted aging and anti-aging theories in the last century and postulated his new aging theories and anti-aging strategies in The Scientific Pages of Dermatology (TSPD). Chiou said this may have many very important implications and applications in future aging and anti-aging research. This and his other recent breakthroughs are disclosed.

Classical Cumulative Oxidative Stress/Accelerated Aging Theories QuestionedSurprisingly, these important classical theories were not supported by results from his critical analyses of reported aging data of human hearts and skin from a large number of normal subjects over many decades of lifespan. Some implications are: Generally, our skin and heart actually don't age faster as we get older as predicted from these accelerated aging theories. Also, we may have over-emphasized the use of purified anti-oxidants in dietary supplements to combat aging. This is because oxidative stress has been traditionally regarded as the culprit of our aging.

Classical Photoaging Theory Questioned: Intrinsic Aging as Root CauseThe photoaging theory claims that exposure to sunlight contributes about 80% of our skin aging. Chiou astoundingly found that sun exposure had no noticeable effects on the aging of skin collagen and superficial capillaries in their lifetime. Furthermore, age spots, commonly assumed to result from photoaging, were frequently found to occur on thighs, forearms and backs in seniors that were rarely exposed to sunlight. Chiou asked: Do we need to re-evaluate general recommendations that we should wear sunscreens as a daily ritual when we go outdoors? How much SPF number do we really need? This is especially significant because exposure to sunlight has many important health benefits such as reducing blood pressure, heart attacks and strokes, and increasing the immune system and vitamin D synthesis. These benefits are known to far outweigh the risks such as skin cancer.

New Cardiac-Output-Reduction Aging Theory: Utmost Importance of Cellular Nutrients in Determining Cellular/Tissue Aging

Chiou postulated a new theory that since our heart pumps nutrient-carrying blood to various organs/tissues to sustain their vitality, therefore, cardiac output should be closely related to our life expectancy and general health. Chiou said that we age mainly because our cardiac output decreases and cellular levels of nutrients in peripheral tissues also decrease with age. Cardiac output peaks at about age 12. By age 40 and 80, it can decrease very significantly by 30% and 49% respectively. Hence, Chiou postulated that one effective approach to combat body aging and to increase longevity is to increase cardiac output through stem-cell rejuvenation and to increase tissue nutrients. In other words, aging is reversible!!

New Theories for Formation of Wrinkles and Age Spots: Intrinsic Aging as Root CausesFor the first time, Chiou theorized that formation of wrinkles in aged adults results from body's defense mechanism in order to reduce effective surface area for minimizing environmental assaults. And the formation of age spots mainly results from birth defects and later acquired injuries in superficial capillaries that nourish the skin. Hence these disorders are generally first initiated by intrinsic aging. Sunlight may hasten the above problems. Chiou noted that young children and youths with healthy skin may stay outdoors unprotected daily for months or years without developing age spots or wrinkles.

New Strategy to Combat and Reverse Skin Aging: Stem-Cell RejuvenationJust as water can revitalize a dry wilted flower, an aging-reversing phenomenon, Chiou has developed a unique proprietary body-natural (ingredients being natural in our body) nutritional serum, Eternal Spring Serum (ESS), to be topically applied daily to rejuvenate our skin. Surprisingly, the firming and tightening effects are almost universally observed in all users. A stunning example is shown in his wife, Linda Chiou, who has used the product for more than 10 years and rarely used sunscreens. At age 75, her skin seems much better than many others 25 to 35 years younger (Figure 1). Many friends noticed her skin-age-reversing phenomenon. It is reasoned that the ESS must work via rejuvenation of stem or progenitor cells in the skin. Currently, skin reversal is considered by dermatologists as impossible to achieve. Therefore, the ESS represents a historical breakthrough in combating skin aging.

Growth Acceleration and Regeneration of Human Nails: Stem-Cell RejuvenationLiquid preparations containing body-natural nutrients have been shown to quickly accelerate nail growth or to regenerate new nails after nail injury in numerous subjects. This may be the first of its kind ever reported (patent pending). Such effects are also postulated to be due to stem-cell/progenitor cell rejuvenation. Interestingly, this approach also helps grow new hair on Dr. Chiou's decades-old baldhead.

Dr. Chiou is an editor for TSPD, and is organizing a Special Issue on "Aging and Anti-Aging". He was a former university professor for 36 years. Dr. Chiou is currently President of Winlind Skincare LLC and Chiou Consulting Inc. His detailed biography is available at the TSPD website.

Eva Feldman is stepping down as director of the A. Alfred Taubman Medical Research Institute at the University of Michigan, but at the age of 65, she has no intention of retiring.

She was the founding director of the institute created with tens of millions of dollars from mall mogul A. Alfred Taubman to fund research into intractable diseases like Alzheimer's, ALS and diabetes and ran it for 10 years. It is time, she says, for her next, but not necessarily last, 10-year plan.

"I birthed a baby and it's grown to be 10. It's a tweener, now, and ready for someone else to take it to adolescence," she told Crain's, following a meeting she had with one of the finalists of a national search to replace her.

Feldman said she expects a replacement to be named by the end of June.

"We started with four people, and now we have more than 200 investigators," she said. "We're strongly established, very robust. We have the best scientist-clinicians at the university. It's time for the next director to take over. There are other things I want to do, now. This takes up a lot of time, and I want to spend more time on my own research."

Feldman will continue to run the ALS Clinic at UM. Each Tuesday, she and a small staff diagnose and treat patients with amytrophic lateral sclerosis, sometimes known as Lou Gehrig's disease. The Russell N. DeJong Professor of Neurology at the U-M Medical School, she will also continue to run her own 30-scientist laboratory, the Program for Neurology Research & Discovery.

She said her new 10-year plan has three major goals.

This would be the last trial before the procedure is approved.

As soon as Feldman was done enumerating those goals, she enumerated two more.

She wants to help get more women into research positions at major universities. "More women than men graduate from the medical school at Michigan, but there are just a blip of women who are full professors," she said.

Last Wednesday, she and the Taubman Institute hosted a symposium called "Strategies to Empower Women to Achieve Academic Success," with keynote speakers on gender equality in academic medicine and a panel discussion on how to use negotiation and networking skills for career advancement.

And she wants to raise the $5 million it will take to fund the large-animal studies she needs to do before she can launch FDA human trials using embryonic stem cells to treat Alzheimer's. She said stem-cell trials with mice with dementia have been promising.

Researchers injected two groups of Alzheimer's mice, one group with a saline solution to serve as a control, the other with stem cells. Both of those groups and a group of healthy mice were then put through three tests of cognition, including one that required finding a platform hidden in a pool of water.

Previously, both sets of Alzheimer's mice flunked the cognition tests. After the stem-cell injections, the Alzheimer's mice injected with cells performed the tests as well as healthy mice. The Alzheimer's mice injected with saline solution flunked the tests.

"I am persistent. I will get that funded," she said.

Feldman took a sabbatical this spring to go to Australia, where she helped the Royal Children's Hospital in Melbourne set up a neuropathy-screening program for children with diabetes, which dovetails with one of her clinical trials treating neuropathy in children. And in September she heads to Chennai, India, to set up a similar program at a hospital there.

Neuropathy is a painful condition resulting from the nerve damage that diabetes can cause.

Feldman has published more than 350 peer-reviewed articles, 60 book chapters and three books and has had continuous funding from the National Institutes of Health for more than 20 years, including 12 current grants totaling about $5.5 million.

She is past president of the Peripheral Nerve Society and served as president of the American Neurological Association from 2011 to 2013, the group's third woman president in 130 years. Last June, she was named among the 100 most influential women in Michigan by Crain's.

Scores of people living with multiple sclerosis have put themselves forward for clinical trials as part of a Cambridge scientists bid to develop a treatment to cure the disease.

MS, an auto-immune condition which affects 2.3 million people around the world, attacks cells in the brain and the spinal cord, causing an array of physical and mental side effects including blindness and muscle weakness.

At the moment theres no cure, but Cambridge scientist Su Metcalfe and her company, LIFNano, hope to change that.

On Sunday the News told how Su has married one of the bodys cleverest functions with some cutting-edge technology. The natural side of the equation is provided by a stem cell particle called a LIF.

Su said: I discovered a small binary switch, controlled by a LIF, which regulates inside the immune cell itself. LIF is able to control the cell to ensure it doesnt attack your own body but then releases the attack when needed.

That LIF, in addition to regulating and protecting us against attack, also plays a major role in keeping the brain and spinal cord healthy. In fact it plays a major role in tissue repair generally, turning on stem cells that are naturally occurring in the body, making it a natural regenerative medicine, but also plays a big part in repairing the brain when its been damaged.

So I thought, this is fantastic. We can treat auto-immune disease, and weve got something to treat MS, which attacks both the brain and the spinal cord. So you have a double whammy that can stop and reverse the auto-immunity, and also repair the damage caused in the brain.

Sus company LIFNano has already attracted two major funding awards, from drug firm Merck and the Governments Innovate UK agency.

The company hopes to attract more investment, with the aim of starting clinical trials in 2020.

Off the back of the article regarding Sus work, people commented in their droves offering to trial Dr Metcalfes treatment, which is being touted as a possible cure.

Many also shared their experiences of living with MS.

James Stokes, 52 from Reading, was just one of many to comment on our story.

He told the News : I was diagnosed with MS on my 18th birthday of all days, but I wasnt told then that it was MS.

I had a big attack and was put in hospital; I lost my sight and couldnt speak or walk.

Even then I still wasnt officially told it was MS until a few years later.

About 10 years ago, things started to go downhill and I found myself basically housebound; I can still walk but not a great distance.

I use a walking stick, and have to use a wheelchair if Im going long distances.

MS has robbed me of my life, but when I saw this article there was a glimmer of hope.

Id love to know more about it [the process] and would be willing to take part in clinical trials.

If they could reverse my MS that would mean everything. At the moment, I feel as if Ive been given a life sentence but with no parole.

If a cure for MS is found, I could get a new lease of life and a lot more hope.

Many others also commented on the story regarding Sus work.

Debbie Brown wrote: This gives me some hope that things will improve in my lifetime. Diagnosed with RRMS in 2000. Very interested in registering for a clinical trial.

Amy Keighley said: My father was diagnosed with MS in 1996. He has been on several medications and is currently being treated by Dr Tornatori at Georgetown University Medical Center.

He fights every day and lives life to the fullest. He and my mother have been together since 1950. They were 15 years old. They are both retired from operating a jewellery store together for 23 years.

They try to travel every month and my dad's spirits remain high. I would like to ask that my dad be considered for the clinical trial.

While the search for possible cures for cancer continue in laboratories around the world, exciting new research turns our attention to a commonly available, inexpensive vitamin. Thats because a humble vitamin has been found to seek out and destroy cancer stem cells, which are cells that are believed to drive the creation of new cancer cells and cancer tumors.

The study, published in the medical journal Oncotarget, found that vitamin C can actually seek out and destroy cancer stem cells, thereby preventing the spread of the disease. Vitamin C was found by researchers to be up to 10 times more effective at killing cancer stem cells than experimental drugs. Thats good news considering the toll that cancer is currently taking. Cancer is currently the second leading cause of death and killed almost 9 million people in 2015 alone.

Lead study author Dr. Michael P. Lisanti, professor of translational medicine at the University of Salford said in an interview with Medical News Today: We have been looking at how to target cancer stem cells with a range of natural substancesbut by far the most exciting are the results with vitamin C. Vitamin C is cheap, natural, nontoxic and readily available, so to have it as a potential weapon in the fight against cancer would be a significant step.

Vitamin C is found in most fruits and vegetables, but especially in red bell peppers, strawberries, oranges, grapefruit, lemons, limes, pomegranates, black currants, spinach, beet greens, tomatoes and sprouts. Eating a plant-based or largely plant-based diet high in vitamin C-rich foods may be helpful in preventing or treating cancer, but supplementation may be necessary to achieve the study results. Vitamin C is available in a variety of forms, with ascorbic acid being the primary one, along with other buffered options such as calcium ascorbate. The Oncotarget study found that ascorbic acid effectively sought out and destroyed cancer stem cells.

It is not clear how much vitamin C is necessary to create the anti-cancer results. More research may help to determine the ideal dosage. The recommended dietary intake is 90 milligrams of vitamin C, but many natural health experts believe that this amount is extremely low and doesnt take stress or diseases like cancer into account. Stress causes the rapid depletion of vitamin C. Our stress glands, the adrenal glands, which are two small, triangular-shaped glands that sit atop the kidneys in the abdominal region, use high amounts of vitamin C, particularly when they are dealing with acute or chronic stress. Many natural health experts recommend 2000 milligrams of vitamin C daily, and sometimes even more than that if it is part of a therapeutic protocol.

Nobel Prize winner Dr. Linus Pauling first discovered vitamin C and its role in fighting cancer. This new Oncotarget study builds on Dr. Paulings research, showing that vitamin C also targets cancer stem cells, an important advancement in our knowledge of cancer and vitamin C. Other research published in the medical journal Science found that high doses of vitamin C may help in the treatment of colorectal cancer. It is a good idea to work with a naturally-minded health professional if you intend to take high doses of vitamin C, divided throughout the day.

Because vitamin C is water soluble, it is not stored in our body and must therefore be ingested on a daily basis to avoid a deficiency. Some of the symptoms of a vitamin C deficiency include: excessive hair loss, becoming exhausted easily, fragile bones, frequent nosebleeds, gums that bleed easily, skin that bruises easily, and sores or wounds that heal slowly.

Vitamin C is also crucial to the formation of bones and teeth, digestion, blood cell formation, wound healing and the production of collagen, which is involved in maintaining the skins youthful elasticity.

About the SCiStar Trial

The SCiStar trial is an open-label, single-arm trial testing three sequential escalating doses of AST-OPC1 administered at up to 20 million AST-OPC1 cells in as many as 35 patients with sub-acute, C-5 to C-7, motor complete (AIS-A or AIS-B) cervical SCI. These individuals have essentially lost all movement below their injury site and experience severe paralysis of the upper and lower limbs. AIS-A patients have lost all motor and sensory function below their injury site, while AIS-B patients have lost all motor function but may retain some minimal sensory function below their injury site. AST-OPC1 is being administered 14 to 30 days post-injury. Patients will be followed by neurological exams and imaging procedures to assess the safety and activity of the product.

The study is being conducted at six centers in the U.S. and the company plans to increase this to up to 12 sites to accommodate the expanded patient enrollment. Clinical sites involved in the study include the Medical College of Wisconsin in Milwaukee, Shepherd Medical Center in Atlanta, University of Southern California (USC) jointly with Rancho Los Amigos National Rehabilitation Center in Los Angeles, Indiana University, Rush University Medical Center in Chicago and Santa Clara Valley Medical Center in San Jose jointly with Stanford University.

Asterias has received a Strategic Partnerships Award grant from the California Institute for Regenerative Medicine, which provides $14.3 million of non-dilutive funding for the Phase 1/2a clinical trial and other product development activities for AST-OPC1.

Additional information on the Phase 1/2a trial, including trial sites, can be found at http://www.clinicaltrials.gov, using Identifier NCT02302157, and at the SCiStar Study Website (www.SCiStar-study.com).

About AST-OPC1

AST-OPC1, an oligodendrocyte progenitor population derived from human embryonic stem cells, has been shown in animals and in vitro to have three potentially reparative functions that address the complex pathologies observed at the injury site of a spinal cord injury. These activities of AST-OPC1 include production of neurotrophic factors, stimulation of vascularization, and induction of remyelination of denuded axons, all of which are critical for survival, regrowth and conduction of nerve impulses through axons at the injury site. In preclinical animal testing, AST-OPC1 administration led to remyelination of axons, improved hindlimb and forelimb locomotor function, dramatic reductions in injury-related cavitation and significant preservation of myelinated axons traversing the injury site.

In a previous Phase 1 clinical trial, five patients with neurologically complete, thoracic spinal cord injury were administered two million AST-OPC1 cells at the spinal cord injury site 7-14 days post-injury. They also received low levels of immunosuppression for the next 60 days. Delivery of AST-OPC1 was successful in all five subjects with no serious adverse events associated with AST-OPC1. No evidence of rejection of AST-OPC1 was observed in detailed immune response monitoring of all patients. In four of the five patients, serial MRI scans indicated that reduced spinal cord cavitation may have occurred. Based on the results of this study, Asterias received clearance from FDA to progress testing of AST-OPC1 to patients with cervical spine injuries, which represents the first targeted population for registration trials.

If youve donated blood, you probably received a follow-up message asking you to consider a platelet donation. Donation centers must constantly replenish their blood supplies, but the need for platelets is particularly acute. Compared to other components of blood, platelets are fragile and short lived, which puts high demand on the small supply of these cell fragments that are key to stopping bleeding.

Plasma separated from blood can be frozen and red blood cells can be refrigerated for up to 42 days. But platelets, which must be stored at room temperature, last just five days. After pathogen screening and transport, platelets have about two days to reach a patient, says Sven Karlsson, president and co-founder of Boston-based Platelet Biogenesis.

Karlssons startup aims to bring hospitals an alternative: platelets produced as needed from stem cells. Platelet BioGenesis, a spinout from Harvard University and Brigham and Womens Hospital, now has $10 million from a Series A round of funding to support preclinical testing of its regenerative medicine technology.

The body produces the components of blood in bone marrow. Platelets are made by a type of bone marrow cell called a megakaryocyte. Platelet Biogenesis produces its platelets in a two-step process. It first develops megakaryocytes from stem cells in culture, Karlsson says. Next, the megakaryocytes are fed into a device that the company developed that puts the cells through a process the company says is similar to what occurs in natural bone marrow physiology and results in the production of platelets.

Were making real, functional platelets, Karlsson says. Instead of mimicking the platelet, were mimicking the process of making a platelet.

Platelet transfusions are needed by patients whose bodies dont produce enough platelets, as well as those who have clotting problems. These transfusions are also used to treat patients who have cancer or are undergoing surgery. Since most platelet donation centers are in urban areas, the short shelf life of platelets makes supplies tight in rural areas. Donations dont entirely solve the problem, Karlsson says. While donating whole blood takes about 15 minutes, platelet donation takes 90 minutes, which makes it harder to get donors.

Researchers have tried to address the platelet shortage problem by developing synthetic platelets. But Karlsson says that the synthetic versions can cause side effects. The idea for replicating the bodys process of producing platelets stems from more than a decade of research. Jonathan Thon, the CEO and co-founder of Platelet BioGenesis, was pursuing ways to extend the shelf life of platelets. But Karlsson says Thon concluded a better approach might be developing a way to replace human donors. As a post-doctoral researcher at Harvard, he invented a microfluidic device that mimics a human bone marrow.

Before Platelet BioGenesis can bring its platelet-making technology to the market, it will need FDA approval. The regulator treats blood products as therapeutics, which means that the company will need to conduct clinical trials. Karlsson says the funding round will support preclinical research. Within three years, he expects the startup will be able to start Phase 1 safety studies. For those trials, Platelet BioGenesis will need to raise additional funds. The current financing round was led by Qiming US Healthcare Fund and included participation from Vivo Capital, VI Ventures, Adena Partners, eCoast Angels, as well as other unidentified investors.

If Platelet BioGenesis wins FDA approval, Karlsson says the company plans to become a manufacturer, selling its platelets in the existing blood supply chain. Its early to talk about pricing, but he says that Platelet Biogenesis products could be more affordable because they are produced from a pathogen-free source. They could also be produced on demand. While the startups platelets should have the same shelf-life as platelets from human donors, Karlsson says that the parent cells that produce platelets can be stored frozen. When platelets are needed, thawed cells can be placed in the companys microfluidic device, which produces platelets within hours.

Karlsson says Platelet BioGenesis might be able offer another advantage: beating the five-day shelf life of donor platelets. In the body, a platelet lasts 10 days. If all of Platelet BioGenesis platelets are born on the same day, they should theoretically have the same 10-day life, he says. Thats one of the things the company plans to test in upcoming trials. The company will also evaluate its platelets to make sure that they are comparable to donor platelets.

June 8, 2017 One example of STAT1 GOF Mutation phenotype. Credit: Hiroshima University

Researchers report the first-ever study assessing how patients with "gain of function" mutation of the STAT1 gene respond to stem cell transplantation. It involved 15 young patients from nine different countries, each suffering a range of complications caused by the gene's mutation.

Of these, only six survived a regime of stem cell transplantationwith five completely cured and disease free by the study's conclusion.

The study was carried out by Dr. Satoshi Okada (Hiroshima University), Professor Jennifer Leiding (University of Florida), Professor Tomohiro Morio (Tokyo Medical and Dental University), and Professor Troy Torgerson (University of Washington).

Dr. Okada, who first discovered the STAT1 gain of function mutation in 2011, says, "Overall, this result is disappointing but the fact that five patients were cured proves that treatment with stem cells can work, and we now need to learn from these 15 individual cases."

The STAT1 gene plays a vital role in the body's immune system. Rare mutations can lead to STAT1's over-activation (GOF) and autoimmunity.

While the majority of patients afflicted typically show mild to moderate symptoms involving fungal (mostly Candida), bacterial, and viral infectionsabout 10 percent of cases are severe and life threatening.

Until now, developing suitable treatments has been challenging; e.g. anti-fungal drugs temporarily treat the symptoms but not the source mutation, and immunosuppressive therapies often do more harm than good by knocking out already overburdened immune systems.

With only one confirmed case prior to this study of a sufferer being successfully cured using stem cell transplantation, researchers are keen to build an understanding of best practices in order to offer real hope for the typically young sufferers of this condition.

The 15 selected patients were sourced via an international appeal to transplant centers and consortiums. Their ages ranged from 13 months to 33 years at the time of treatment. Screening by HU researchers confirmed that each had the STAT1-GOF mutation, and that the mutation was the source of their ailments.

Treatment was carried out independently by centers around the world. It used chemotherapy to eradicate the host's bone marrowthe source of the damaging STAT1 mutation in these patients. Healthy stem cell cultures sourced from donors were then transplanted into the subjects with the aim of reconstituting their bone marrow to a mutation-free, disease-fighting state.

The researchers suspect three reasons for the low 40 percent success rate:

In response, the researchers have made several proposals for improving this treatment. Due to most of the patients having mild to moderate ailments, only those suffering from severe symptoms should undergo this treatment. In addition, the chemotherapy dosage should be reduced. Those who received low-dose chemotherapy reacted better.

However, a balance must be struck. Low-dose chemotherapy may not eradicate host bone marrow to the extent required for its reconditioning the chance of transplant rejection is thus increased. With this in mind, support treatment may be required to neutralize host antibodies and prevent attacks of introduced stem cells.

Finally, due to the relative success seen in younger patients, stem cell transplantation should occur at as early an age as possible. Due to recent advancements in STAT1-GOF diagnosis, early detection is now a very real possibility hopefully leading to greater success rates, and less suffering for those carrying this potentially devastating mutation.
