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.

When 14-year-old Aarav Gulati (name changed on request) met with an accident a couple of years ago while playing football, he injured his knee. A portion of the cartilage was damaged, and doctors used turned to a radical new procedure for a solution. They took Gulatis own cells, grew them in a lab and used them to replace the cartilage and repair the damage in a natural way.

He was an ideal case for the use of regenerative cell therapy that was a fairly new phenomenon in orthopaedic treatment in India, says Dr Yash Gulati, senior joint replacement and spine surgeon, New Delhis Indraprastha Apollo Hospital.

The regenerative cell therapy got US FDA approval this year, and the Apollo group partnered with RMS REGROW, a company that specialises in cell therapy technology, to exclusively offer the treatment to patients in India.

Instead of using artificial implants, the technique helps in healing the bone or cartilage damage in a natural way using a persons own cells to regain normal function. Cultured cells (grown in a lab) are injected into a patient to replace diseased or dysfunctional cells.

A small part of the joint cartilage is taken through a keyhole procedure, and is grown in a special manner to convert it into stem cells in the laboratory, says Dr Gulati. This is then applied on the area showing loss of joint cartilage.

Dr Gulati has so far treated 10 people using this therapy in Apollo, Delhi.

Stem cells lead to growth of joint cartilage in defective areas, and normal new cartilage re-grows. In bone damage, bone marrow cells are harvested, cultured and implanted in the area to be able to re-grow in a healthy way, Dr Gulati says.

In Mumbai, those in need of joint replacement because of injury, wear and tear or other lifestyle and ageing, are also realising that new cartilage can be grown in a lab from ones own cells and used instead of artificial materials.

Chondron or cartilage cell therapy is a patient-specific regenerative medical treatment which naturally regrows original cartilage. The therapy is used for repairing articular cartilage of the knee, ankle and shoulder joints and to help replace missing areas of cartilage.

This is a process where a biopsy of cartilage cells (chondrocytes) is taken from the patients knee, ankle or shoulder, says Satyen Sanghavi, chief scientific officer of Regenerative Medical Services Regrow, a biotechnology company in Mumbai.

Causes of bone or cartilage damage

They are then cultured to grow and multiply in a lab for 3-4 weeks into a surplus population of several million. The cultured cells are then re-implanted in the damaged area in a minimally invasive surgical procedure.

The process comes from eight years of work in cell and tissue therapy research. Chondron ACI is the countrys first cell therapy product.

These cells grow and repair tissue with properties similar to that of normal cartilage present in other joints, says Sanghavi. But replacement alone doesnt solve problems. Patients are expected to follow a rehabilitation program, to help the body adjust to new cells and them get back to day-to-day physical.

Its easy to see the advantages of a process like this. Experts say it may avoid the need for future prosthetic joints replacement (especially partial joint replacement) and allows patients the freedom to continue physical activities as before.

It also poses less risk of disease transmission or infection since it comes from the patients own tissue (no foreign material or metal goes inside the body). It may also halt further progression to osteoarthritis, a common problem with those in need of joint replacement.

The procedure costs Rs.3 to 3.5 lakhs.

In India, more than 500 patients have been treated with both bone and cartilage cell therapy procedures, says Sanghavi.

There is a success rate of more than 95%. During our clinical trials and research, we have treated working professionals, housewives, athletes, army men and mountaineers. Almost all of them have successfully recovered and got back to their active life.

However, this new technique has a flip side, too.

The price could be a bit steep for some because stem cell treatment is expensive; and the treatment gets prolonged as a patient has to wait for some time as cell culture takes time and one cannot bear weight on the affected area while the healing is on. Also, not all patients are suitable for it because it can correct only if damage isnt extensive, says Dr Ankit Goyal, associate professor, Safdarjung Sports Injury Centre (SIC) in Delhi.

Safdarjung Hospital had also treated about 35 patients, who had damaged their cartilage, with the technique a few years ago.

We would send cartilage for culture but only in cases where damage was limited. This is definitely not a substitute for knee or hip replacement procedure where the entire joint is extensively damaged. However, it may prevent the need for replacement later on in life, especially in young patients, he says.

Damaged bone or cartilage? Now, grow your own cells in a lab - Hindustan Times

LUCY Clarke was facing a downhill spiral when she flew to Russia to undergo a cutting edge stem cell transplant.

Two years on she says the procedure not only halted her illness in its tracks, but reversed much of the damage inflicted by multiple sclerosis.

The 41-year-old from Inverness is now backing crowdfunding efforts so that her friend and neighbour, Rona Tynan, can receive the same life-changing operation in Mexico before she becomes too ill to qualify.

Mrs Tynan, 50, has until the end of August to raise the 60,000 needed.

However, both are angry at a cross-border divide which means that a small number of MS patients in England can undergo the treatment for free on the NHS, while in Scotland despite having some of the highest rates of MS in the world the health service has refused patients' funding and no clinical trials are planned.

Mrs Clarke, a chemistry graduate and acupuncturist, began investigating AHSCT (autologous haematopoietic stem cell transplantation) in 2014 after her condition progressed from relapsing-remitting to secondary progressive MS. At the time her son was three and she feared ending up in a wheelchair.

Although the treatment has been available overseas for decades, it has never been routinely available on the NHS and is considered unproven by many neurologists.

It is also a highly aggressive therapy, using intensive chemotherapy to strip out sufferers faulty immune systems before replenishing it with stem cells harvested from their own bone marrow or donor tissue. Despite the risks, many patients including Mrs Clarke credit it with transforming their lives.

She underwent the procedure in Moscow over a period of four weeks in April and May 2015. She said: From when my son was three to when I had the transplant, my walking had deteriorated, I needed to use a walking stick all the time, I had very poor balance, debilitating fatigue, I had brain fog, I used to slur my words.

"Im left-handed and my left hand was really weak so my writing was bad. Other things would come and go numbness in my legs, tingling, cramps in my calves, sore and painful legs. The majority of them have gone since the transplant.

I noticed quite quick improvements in things like balance. The biggest thing is not really having fatigue, and the brain fog completely went. I stopped slurring my words quite quickly after treatment. I was more alert. I had more concentration, more focus. Within six months the shaking in my left arm had gone. Ive still got drop foot in my right leg and I still use a walking stick, but once youve got to the stage of secondary progressive it all gets a bit scary. Things are going downhill and youre told theres nothing that can be done, so really my goal from treatment was just to halt the progression to know I wasnt getting any worse. Thankfully, and luckily, I have seen lots of benefits.

Eighteen months on, MRI brain scans show no signs of disease progression and while Mrs Clarke stresses that the treatment is neither a magic bullet nor a walk in the park, she is supporting Rona Tynans bid to undergo the same surgery in October.

Mrs Tynan, a retired Metropolitan police sergeant and mother-of-two from Inverness, also has secondary progressive MS. She is already in a wheelchair and fears that unless she undergoes the treatment soon she will become too ill. She said: Im a 7.5 out of 10 on the disease progression scale, where 10 is death. Most clinics stop taking you at seven, but Mexico just raised it to 8.5. Thats brilliant for people like myself, but I cant afford to get any more ill.

So far, Mrs Tynans fundraising page on JustGiving has raised nearly 4000, but she is frustrated that more is not being done to help Scottish patients. In England, clinical trials are ongoing in London and Sheffield but a small number of patients with relapsing-remitting MS can be referred for the treatment off-trial, for free, on the NHS. In Scotland, however, eligible patients have been turned down for NHS funding.

Mrs Tynan said: It seems crazy to me that Brits are going to Chicago and Mexico and Russia for a treatment that in the long-run could save the NHS loads of money. Scotland is one of the worst places in the world for MS yet in England you can get this treatment for free. Why arent we fighting in Scotland to get this?

Mrs Clarke added: Its very unfair. It just seems a no brainer to me why they wouldnt make it available not for all patients but for some. The Scottish Government said referral decisions were "for clinicians".

A spokesman said: "Whilst the vast majority of healthcare provided by NHS Scotland is delivered in Scotland, NHS boards can commission treatment in other countries on an ad hoc basis, particularly where highly specialised treatment is involved. Decisions to refer patients are for clinicians, based on agreed guidelines, which ensure best practice, equity of access and consistency of treatment for all patients.

"HSCT is not currently widely available anywhere on the NHS, but people from Scotland can participate in trials held in other centres across the UK, where clinically determined appropriate and beneficial."

BOSTON - Its been nearly four years since a bone marrow donation saved Mandy Manocchios life, but the anticipation of the last few hours before she met the donor seemed like they took forever.

"When you hear that you have less than a year to live and your life's basically laying on the line and if I didn't find a donor it would've been catastrophic, but she's my angel, she said.

At Brigham and Women's Hospital in November 2013, Mandy had a bone marrow transplant to treat acute myeloid leukemia - on Friday night at The Harp in Boston she finally got to meet Magdelena Kruger, the woman who saved her life.

"She allowed me to watch my children grow up and have another, Mandy said.

Kruger had just landed after an 11-hour flight from Germany. When the two women saw each other there was no need for words.

Stem cells from Kruger were carried 4,000 miles from Germany. Through a translator, she said it was the first time shed ever donated.

I just wanted to help somebody who's sick and needs help, she said.

Now both women are advocates for bone marrow donations. They say the process is relatively simple and life-changing on both ends.

"It's so rewarding to see that immediate result of how you can help somebody, Kruger said.

SOUTH SAN FRANCISCO, CA--(Marketwired - June 29, 2017) - VistaGen Therapeutics Inc.(NASDAQ: VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders, today reported its financial results for its fiscal year ended March 31, 2017.

The Company also provided an update on its corporate progress, clinical status and anticipated milestones for AV-101, its orally available CNS prodrug candidate in Phase 2 development, initially as a new generation treatment for major depressive disorder (MDD).

"With a team of industry experts and a focused strategy in place, we have established a strong foundation and embarked on paths to achieve several key catalysts within the next 18 months. We anticipate our first catalyst within the next 9 months as the NIMH completes its AV-101 Phase 2 monotherapy study in MDD, a study being conducted and fully funded by the NIH. Additionally, we are working closely with the FDA and our Principal Investigator, Dr. Maurizio Fava of Harvard University Medical School, on our AV-101 Phase 2 adjunctive treatment study in MDD, which we anticipate will begin enrollment in the first quarter of 2018 and be completed by the end of 2018, with topline results available in the first quarter of 2019," commented Shawn Singh, Chief Executive Officer of VistaGen.

In addition to MDD, AV-101 may have therapeutic potential in several other CNS indications where modulation of NMDA receptors, activation of AMPA pathways and/or active metabolites of AV-101 play a key role, including for treatment of epilepsy, as a non-opioid alternative for management of neuropathic pain, and to address certain symptoms associated with Parkinson's disease and Huntington's disease.

Mr. Singh continued, "Our MDD clinical program is our top priority, and will remain so. Additionally, however, recent peer-reviewed publications suggest that AV-101 may have significant therapeutic potential as a non-opioid treatment alternative for pain management. We are also excited about AV-101's potential to reduce dyskinesia associated with standard levodopa, or L-DOPA, therapy for Parkinson's disease, based on results from previous non-clinical studies. Without diverting our priority focus on MDD, we plan to expand our AV-101 Phase 2 clinical program during the next year to include these important CNS indications with significant unmet need."

"We are also pleased to have advanced our cardiac stem cell program during fiscal 2017, through both our participation in the FDA's CiPA initiative focused on using novel human stem cell models to predict cardiac toxicity of new drug candidates long before animal and human studies, as well as our exclusive sublicense agreement with BlueRock Therapeutics, an emerging force in cardiac regenerative medicine, founded and funded by Bayer AG and Versant Ventures. Our initial revenue-generating milestone with BlueRock Therapeutics was completed during fiscal 2017. We are optimistic about this relationship's potential and the future of cardiac regenerative medicine. We believe these significant events over the past year have positioned us to create substantial value for our stakeholders in fiscal 2018 and beyond."

Potential Near-Term Milestones:

Operational Highlights During Fiscal 2017:Achievements Related to Stem Cell Technologies

Advancement of AV-101 as a Potential, Non-Opioid Treatment Alternative for Chronic Pain

Bolstered Team with Industry Experts

Intellectual Property Accomplishments

Capital Market Highlights

Financial Results for the Fiscal Year Ended March 31, 2017:

Revenue for the fiscal year ended March 31, 2017 totaled $1.25 million and was attributable to a sublicense agreement with BlueRock Therapeutics, for certain rights to the Company's proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease.

Research and development expense totaled $5.2 million for the fiscal year ended March 31, 2017, an increase of approximately 33% compared with the $3.9 million incurred for the fiscal year ended March 31, 2016. The increase in year-over-year research and development expense was attributable to increased focus on development of AV-101, including preparations to launch the Phase 2 Adjunctive Treatment Study in MDD.

General and administrative expense decreased to $6.3 million in the fiscal year ended March 31, 2017, from $13.9 million in the fiscal year ended March 31, 2016, primarily as a result of the decrease in non-cash stock compensation expense, partially offset by an increase in non-cash expense related to grants of equity securities in payment of certain professional services during fiscal 2017. Of the amounts reported, non-cash expenses, related primarily to grants or modifications of equity securities, totaled approximately $3.1 million in fiscal 2017 and $11.9 million in fiscal 2016.

Net loss for the fiscal years ended March 31, 2017 and 2016 was approximately $10.3 million and $47.2 million, respectively, the latter amount including a non-recurring, non-cash expense of approximately $26.7 million attributable to the extinguishment of approximately $15.9 million carrying value of prior indebtedness, including then-outstanding Senior Secured Convertible Notes, and conversion of such indebtedness into equity securities between May and September 2015 at a conversion price (stated value of the equity received) of $7.00 per share.

At March 31, 2017, the Company had a cash and cash equivalents balance of $2.9 million. Since late-March 2017, the Company sold units consisting of unregistered common stock and common stock warrants to accredited investors in a self-placed private placement, yielding approximately $1 million in cash proceeds to the Company.

About VistaGen

VistaGen Therapeutics, Inc. (NASDAQ: VTGN) is a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders. VistaGen's lead CNS product candidate, AV-101, is in Phase 2 development, initially as a new generation oral antidepressant drug candidate for major depressive disorder (MDD). AV-101's mechanism of action is fundamentally differentiated from all FDA-approved antidepressants and atypical antipsychotics used adjunctively to treat MDD, with potential to drive a paradigm shift towards a new generation of safer and faster-acting antidepressants. AV-101 is currently being evaluated by the U.S. National Institute of Mental Health (NIMH) in a Phase 2 monotherapy study in MDD being fully funded by the NIMH and conducted by Dr. Carlos Zarate Jr., Chief, Section on the Neurobiology and Treatment of Mood Disorders and Chief of Experimental Therapeutics and Pathophysiology Branch at the NIMH. VistaGen is preparing to launch a 180-patient Phase 2 study of AV-101 as an adjunctive treatment for MDD patients with inadequate response to standard, FDA-approved antidepressants. Dr. Maurizio Fava of Harvard University will be the Principal Investigator of the Company's Phase 2 adjunctive treatment study. AV-101 may also have the potential to treat multiple CNS disorders and neurodegenerative diseases in addition to MDD, including neuropathic pain, epilepsy, Huntington's disease, L-Dopa-induced dyskinesia associated with Parkinson's disease and other disorders where modulation of the NMDA receptors, activation of AMPA pathways and/or key active metabolites of AV-101 may achieve therapeutic benefit.

VistaStem Therapeutics is VistaGen's wholly owned subsidiary focused on applying human pluripotent stem cell technology, internally and with collaborators, to discover, rescue, develop and commercialize proprietary new chemical entities (NCEs), including small molecule NCEs with regenerative potential, for CNS and other diseases, and cellular therapies involving stem cell-derived blood, cartilage, heart and liver cells.

Scientists have uncovered how nerve cells in the spinal cord are organised in precise patterns during embryo development - a finding that could give insight into regenerative medicine.

As embryos grow and develop they need the right cell types to end up in the right places inside forming organs. This is particularly important in the spinal cord where different nerve cell types must be accurately positioned so that circuits can assemble properly to control muscle movement. But until now the mechanism underlying nerve cell organisation in the spinal cord has remained poorly understood.

In a study published in Science, researchers at the Francis Crick Institute, the Institute of Science and Technology (Austria) and Ecole Polytechnique Fdrale de Lausanne (Switzerland) report that cells destined to become nerve cells in developing mouse embryos use two different signals spreading from opposite sides of the spinal cord - the back and belly side - to measure their position accurately. Based on this map, they turn into the appropriate nerve cell type. The research was funded by the European Research Council and Wellcome.

The team of biologists, physicists and engineers found that the amounts of the two signals originating from the back and belly sides of the body affect gene activity in developing nerve cells. Based on this gene activity in early development, the cells turn into the appropriate nerve cell type for that position in the spinal cord.

"We've made an important step in understanding how the diverse cell types in the spinal cord of a developing embryo are organised in a precise spatial pattern. The quantitative measurements and new experimental techniques we used, as well as the combined effort of biologists, physicists and engineers were key. This allowed us to gain new insight into the exquisite accuracy of embryonic development and revealed that cells have remarkable ability of to orchestrate precise tissue development," says Anna Kicheva, Group Leader at IST Austria.

"We have shed light on the long-standing question of how developing tissues produce the right cells in the right place in the right numbers," says James Briscoe, Group Leader at the Francis Crick Institute. "It's likely that similar strategies are used in other developing tissues and our findings might be relevant to these cases. In the long run this will help inform the use of stem cells in approaches such as tissue engineering and regenerative medicine. However, there is still much more to learn and we need to continue developing these interdisciplinary collaborations to further our biological understanding."

"With a team of industry experts and a focused strategy in place, we have established a strong foundation and embarked on paths to achieve several key catalysts within the next 18 months. We anticipate our first catalyst within the next 9 months as the NIMH completes its AV-101 Phase 2 monotherapy study in MDD, a study being conducted and fully funded by the NIH. Additionally, we are working closely with the FDA and our Principal Investigator, Dr. Maurizio Fava of Harvard University Medical School, on our AV-101 Phase 2 adjunctive treatment study in MDD, which we anticipate will begin enrollment in the first quarter of 2018 and be completed by the end of 2018, with topline results available in the first quarter of 2019," commented Shawn Singh, Chief Executive Officer of VistaGen.

In addition to MDD, AV-101 may have therapeutic potential in several other CNS indications where modulation of NMDA receptors, activation of AMPA pathways and/or active metabolites of AV-101 play a key role, including for treatment of epilepsy, as a non-opioid alternative for management of neuropathic pain, and to address certain symptoms associated with Parkinson's disease and Huntington's disease.

Mr. Singh continued, "Our MDD clinical program is our top priority, and will remain so. Additionally, however, recent peer-reviewed publications suggest that AV-101 may have significant therapeutic potential as a non-opioid treatment alternative for pain management. We are also excited about AV-101's potential to reduce dyskinesia associated with standard levodopa, or L-DOPA, therapy for Parkinson's disease, based on results from previous non-clinical studies. Without diverting our priority focus on MDD, we plan to expand our AV-101 Phase 2 clinical program during the next year to include these important CNS indications with significant unmet need."

"We are also pleased to have advanced our cardiac stem cell program during fiscal 2017, through both our participation in the FDA's CiPA initiative focused on using novel human stem cell models to predict cardiac toxicity of new drug candidates long before animal and human studies, as well as our exclusive sublicense agreement with BlueRock Therapeutics, an emerging force in cardiac regenerative medicine, founded and funded by Bayer AG and Versant Ventures. Our initial revenue-generating milestone with BlueRock Therapeutics was completed during fiscal 2017. We are optimistic about this relationship's potential and the future of cardiac regenerative medicine. We believe these significant events over the past year have positioned us to create substantial value for our stakeholders in fiscal 2018 and beyond."

Capital Market Highlights

Financial Results for the Fiscal Year Ended March 31, 2017:

Revenue for the fiscal year ended March 31, 2017 totaled $1.25 million and was attributable to a sublicense agreement with BlueRock Therapeutics, for certain rights to the Company's proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease.

Research and development expense totaled $5.2 million for the fiscal year ended March 31, 2017, an increase of approximately 33% compared with the $3.9 million incurred for the fiscal year ended March 31, 2016. The increase in year-over-year research and development expense was attributable to increased focus on development of AV-101, including preparations to launch the Phase 2 Adjunctive Treatment Study in MDD.

General and administrative expense decreased to $6.3 million in the fiscal year ended March 31, 2017, from $13.9 million in the fiscal year ended March 31, 2016, primarily as a result of the decrease in non-cash stock compensation expense, partially offset by an increase in non-cash expense related to grants of equity securities in payment of certain professional services during fiscal 2017. Of the amounts reported, non-cash expenses, related primarily to grants or modifications of equity securities, totaled approximately $3.1 million in fiscal 2017 and $11.9 million in fiscal 2016.

Net loss for the fiscal years ended March 31, 2017 and 2016 was approximately $10.3 million and $47.2 million, respectively, the latter amount including a non-recurring, non-cash expense of approximately $26.7 million attributable to the extinguishment of approximately $15.9 million carrying value of prior indebtedness, including then-outstanding Senior Secured Convertible Notes, and conversion of such indebtedness into equity securities between May and September 2015 at a conversion price (stated value of the equity received) of $7.00 per share.

At March 31, 2017, the Company had a cash and cash equivalents balance of $2.9 million. Since late-March 2017, the Company sold units consisting of unregistered common stock and common stock warrants to accredited investors in a self-placed private placement, yielding approximately $1 million in cash proceeds to the Company.

To help treat varicose veins, scientists need to accelerate the growth of blood vessels, which would be a crucial development for cardiac medicine. A heart attack is caused by damaged arteries, and an ischemic stroke also often results from vascular damage.

"Quite a lot of pathologies regarding veins still remain unstudied," said Igor Mayborodin, a doctor of medical sciences at the stem cell laboratory at ICBFM. "Weve looked into blood flow restoration in situations when there are blood clots. Now were trying to use stem cells to stimulate the growth of veins and bypass the diseased area."

The discovery by Siberian scientists will make it possible to successfully treat diseases of the veins and resulting complications, for example, varicosis, phlebothrombosis (the formation of a blood clot in the vein that leads to its blockage), and even some types of trophic ulcers and cerebral strokes.

Researchers conducted a number of studies on rats, injecting them with stem cells taken from their relatives. The experiment showed that within a week small vessels had formed in the rodents, and in the third week the replacement of the introduced cells with the rodents' own cells began.

The new blood vessels remained in the body but stem cells that formed walls were gradually replaced by those of the rodents. Thus, scientists showed that stem cells can restore blood flow, bypassing damaged veins. Based on the results, a series of articles will be prepared.

Also, scientists witnessed unexpected side effects. "Some of the stem cells die, and then macrophages are attracted to the site, that is, 'ingester' cells capable of actively engulfing and digesting the remains of dead cells," Mayborodin said. "This is what helps a surgical wound be rid of damaged tissue quicker and heal. This is a good result."

The scientists are continuing their state-funded research, and they have obtained a patent for their work. For the time being, however, they cant check the results in clinical tests because Russian law restricts the use of stem cells on humans.

"Wed like to utilize the obtained data in regards to humans, but this is currently not possible," Mayborodin said. "For now were refining the results of the research on cell therapy and clarifying possible complications. But wed like to test our hypothesis at least on a severe case of varicosis in clinical conditions."

Oneyoung Weymouth man is climbing Mount Snowdon on his 21st birthday to help in the fight against cancer.

Paul Cashman-Roberts, 20, is hiking up the mountain on Friday, September 8, to raise money for the Anthony Nolan charity, in support of his aunt and his cousin.

His cousin, Avril Bailey, was diagnosed with breast cancer and had to have one of her breasts removed, while his aunt, Terina Cashman-Stimpson, still suffers from several forms of cancer one of which is blood cancer.

Anthony Nolan works to deliver lifesaving stem cell and bone marrow transplants to those with blood cancer or other blood disorders and conducts vital research into making these transplants more effective.

Paul expressed admiration for both his cousin and his aunt and said he wanted to do something in support of their struggle.

He said: I thought I would do something to raise money for experts who are going to do some fantastic research in the field. I did the Duke of Edinburgh while at Wey Valley School and I love walking my dog all the time.

Paul said that he specifically chose Mount Snowdon to walk up partly because it was more accessible than Ben Nevis.

When he announced he was going to be doing the climb up Snowdon last Thursday Paul received an amazing response from people.

He said: Within the first 24 hours we managed to raise 120.

Initially it was hoped the climb would raise up to 1,000.

Paul added: However, I have been in contact with the guys at Ayya nightclub in Weymouth and we are going to be holding a mini-music festival there to raise even more money.

The young hiker is hoping this will help him to go beyond the 1,000 mark. Both Pauls family and the people at Anthony Nolan have been extremely supportive of him and he is looking forward to his climb up the tallest mountain in England and Wales.

He said: I could not be more thrilled. Really, the end result is about how much we can raise and about saving peoples lives that is really what its all about.

June 27, 2017 Just a few days old embryonic cell clusters: with functional Pramel7 (left), without the protein (right) the development of the stem cells remains stuck and the embyos die. Credit: Paolo Cinelli, USZ

Researchers from the University of Zurich and the University Hospital Zurich have discovered the protein that enables natural embryonic stem cells to form all body cells. In the case of embryonic stem cells maintained in cell cultures, this allrounder potential is limited. Scientists want to use this knowledge to treat large bone fractures with stem cells.

Stem cells are considered biological allrounders because they have the potential to develop into the various body cell types. For the majority of stem cells, however, this designation is too far-reaching. Adult stem cells, for example, can replace cells in their own tissue in case of injury, but a fat stem cell will never generate a nerve or liver cell. Scientists therefore distinguish between multipotent adult stem cells and the actual allrounders - the pluripotent embryonic stem cells.

Epigenetic marks determine potential for development

Differences exist even among the true allrounders, however. Embryonic stem cells that grow in laboratory cell cultures are in a different state than the pluripotent cells found inside the embryos in the first days of development. In a study in the journal Nature Cell Biology, researchers led by Paolo Cinelli of the University Hospital Zurich and Raffaella Santoro of the University of Zurich have now demonstrated the mechanism by which natural allrounders differ from embryonic stem cells in cultures.

At the center of their discovery is a protein called Pramel7 (for "preferentially expressed antigen in melanoma"-like 7) found in the cells of embryonic cell clusters that are just a few days old. This protein guarantees that the genetic material is freed from epigenetic marks consisting of chemical DNA tags in the form of methyl groups. "The more methyl groups are removed, the more open the Book of Life becomes," Cinelli says. Since any cell of the human body can develop from an embryonic stem cell, all genes have to be freely accessible at the beginning. The more a cell develops or differentiates, the stronger its genetic material is methylated and "sealed closed" again. In a bone cell, for example, only those genes are active that the cell requires for its function, the biochemist explains.

Protein is responsible for perfect pluripotency

Despite its short action period of just a few days, Pramel7 seems to play a vital role: When the researchers headed up by Cinelli and Santoro switched off the gene for this protein using genetic tricks, development remained stuck in the embryonic cell cluster stage. In the cultivated stem cells, on the other hand, Pramel7 is rarely found. This circumstance could also explain why the genetic material of these cells contains more methyl groups than that of natural embryonic cells - the perfect allrounders, as Cinelli calls them.

Using the stem cell function to regenerate bone tissue

His interest in stem cells lies in the hope of one day being able to help people with complex bone fractures. "Bones are great at regenerating and they are the only tissue that does not build scars," Paolo Cinelli says. The bone stumps must be touching, however, in order to grow together. When a bone breaks in multiple places and even through the skin, for example, in a motorcycle accident, the sections of bone in between are often no longer usable. For such cases, a bone replacement is required. His team is studying carrier materials that they want to populate with the body's own stem cells in the future. "For this reason, we have to know how stem cells work," Cinelli adds.

Skin Stem Cells Comments Off on What makes stem cells into perfect allrounders – Phys.org – Phys.Org | June 30th, 2017

PROVIDENCE, R.I. (WPRI) Theres a new science on the horizon thats so controversial three experts including one from Brown University have been tasked with studying the ethics of that technology.

The technology has a cumbersome name: in vitro gametogenesis (IVG). But,Brown University professor Dr. Eli Adashi, the schools former dean of medicine and one of the three experts, said itsunlike anything hes seen.

Its mind-boggling, Adashi said. I still feel that way whenever I talk about it.

Right now, IVG is being studied on rodents in Japan and the United Kingdom. The technology reprograms one kind of cell into a different kind of cell.

Of course, everybody who is interested in stem cells is hoping that we will create lungs so that we can replace lung tissue, create hearts so that we can replace heart tissue, said Adashi.

So far, scientists have reported successes in creating egg and sperm cells from non-reproductive cells, like skin.If researchers are successful, this technology could one day eliminate the need for male and female reproductive organs for the creation of life.

Dr. Adashi told Eyewitness News that theres a real possibility this discovery could be adapted for humans, but that a legal, ethical, and political conversation should happen now, before the technology advances any further.

Now is the time to have a conversation, Adashi said. Not against a backdrop of a technology that is already here.

He said a possible advantage of the research would be for people unable to have children, to have an option to do so.

If you could take a skin cell from the individuals and create eggs and sperm that they no longer have intrinsically, you could potentially allow victims of cancer build a family, he said.

He added that the technology could be used for a variety of other benefits such as creating nerve cells to bypass paralysis of the spinal cord.

The ethical evaluation of such a scientific development includes concerns over egg harvesting.

You move from the normal situation where women ovulate a single egg every cycle or [with] in vitro [fertilization] where at the most you would secure 15- 20 eggs, Adashi said. Here you end up with potentially thousands of eggs and you have to ask yourself if this is something we want to get into as a people.

There is no time table for when the research could move from mice to humans. The findings, however, are being increasingly noticed around the world.

The ethics of experimentation: Brown U. prof analyzes controversial science - WPRI 12 Eyewitness News

Skin Stem Cells Comments Off on The ethics of experimentation: Brown U. prof analyzes controversial science – WPRI 12 Eyewitness News | June 30th, 2017

By RENEE WEBB rwebb@catholicglobe.org

As the use of stem cell research and therapy continues to expand, one medical research institute located in Iowa strives to uphold Catholic teachings in bioethics.

The John Paul II Medical Research Institute (JP2MRI), a non-profit of Iowa City, was founded by Dr. Alan Moy in 2007 to address a shortcoming when it came to pro-life values being upheld concerning a variety of medical practices and issues. The doctor also is co-founder and CEO of Cellular Engineering Technologies (CET), a for-profit biotechnology company that manufactures commercial adult stem cells and other biotechnology products.

He explained that JP2MRI was founded a year after starting CET to advance the application of adult stem technology to clinical applications in the area of neurodegenerative disease, rare disease, cancer and chronic diseases of unmet needs or in underperformed diseased areas. His concern was that the United States was falling behind other countries in the area of adult stem cell research.

Recently, through collaborative research by JP2MRI and CET, a new method for creating safer induced pluripotent stem cells, or iPSC, for clinical use was discovered.

We started work in traditional adult stem cells over a decade ago, Moy explained. The controversy was that among the secular scientific community, adult stem cells were viewed as inferior to embryonic stem cells because they could not convert or differentiate into the variety of cells that embryonic stem cells could.

When iPSC technology was discovered by a Japanese Nobel laureate scientist about 10 years ago, it was an ethical alternative to embryonic stem cells. iPSC are noncontroversial adult stem cells that are genetically reprogrammed into embryonic-like stem cells without using human embryos.

But that technology had inherent safety issues just like embryonic stem cells. Most embryonic stem cells and iPS cells have the risk of causing tumors because of their genetic instability, Moy said. What we worked on was trying to reduce the tumor risk.

Building on the original iPSC technology, JP2MRI and CET developed a method by using a variety of chemicals to replace known cancer-causing genes in the process.

Now we have an iPS technology that is safer, said Moy, who noted an added benefit is potential reduced cost in drug development.

Potential applications

He spoke about practical applications of this technology such as expanding the use of stored cord blood stem cells for future medical treatment if a disease develops in the child.

We have a means where we can take the cord blood and make an iPS cell which can have lifelong utility and diversity, Moy added.

For those who do not have stored cord blood, he said all is not lost as blood can be drawn and stored for people to create their own iPS cell for future use.

This technology can also provide a viable alternative to embryonic stem cells and aborted fetal tissue that are currently used by the pharmaceutical industry, noted Moy, to produce vaccines, gene therapy, cell therapy and protein therapeutics.

Right now with protein manufacturing, half of it is done using animal cells to produce human proteins, he explained. The problem is some of the human proteins that are produced have some minor animal characteristics and they are not entirely human so there is a push to produce purely human proteins out of human cells. Unfortunately, the vast majority of human cell lines used in protein manufacturing or in vaccine development are derived from aborted fetal tissue.

Moy anticipates there will increasingly be a movement to shift toward human cell manufacturing, and if we dont come up with non-controversial human cells, we are going to have a lot of controversial human protein therapeutics, gene therapies and vaccines that will be distributed at hospitals that must be administered by doctors.

Morals and ethics

This can create moral and ethical problems. Catholic hospitals and/or Catholic doctors will be forced to decide if they will use that type of product made with illicit cells.

We have to have alternative products that are equal or better than the products that are currently out there, said Moy.

The Catholic Church, as well as the average person, may not always be aware of the unethical nature of many of these products. Moy said he has been trying to communicate areas of concern to the Catholic community for years.

The evolution of biotechnology over decades has become secularized and the power is in the secularists, he said. Advancement of illicit-cell treatment and therapy is a serious potential threat to the Catholic health care system including Catholic hospitals and Catholics who are healthcare providers.

Moy feels strongly about Catholics and the church being pro-active in the bioethics arena.

The only way in which we can influence the biotechnology field is through innovation, he said. Through innovation, if you produce something they want that has technical advantage, then one can influence the direction of biotechnology. Pro-life individuals need to move from a passive bystander to an activist role.

That is part of the reason he founded the JP2MRI, which is grounded in a pro-life bioethics that respects the dignity of every human life. While more than 300 non-profit institutes and organizations engage in and support human embryonic stem cell research, JP2MRI seeks to find cures and therapies exclusively using a variety of adult stem cells and specifically the iPSC, which are derived from adult cells.

Moy said they are not only looking for ways to produce a variety of products using the safer iPS cells, but plan to license them so other scientists, companies and industries can take advantage of these cells to pursue more ethical biotechnology.

Stem cells: JP2MRI, CET discover safer, more ethical biotechnology - Sioux City Catholic Globe

The research studies carried out by John B. Gurdon (Anglo-Saxon) and Shinya Yamanaka (Japanese) were awarded the Nobel Prize in Medicine. These two scientists are considered of being the fathers of cellular reprogramming. They have achieved to create cells that behave identically to embryonic cells, however, without having to destroy human embryos. The Swiss Academy declared that both Gurdon and Yamanaka have revolutionized the current knowledge of how cells and organisms are developed, which has led to the perfection of the absurd methods of diagnosis and therapy.

Jhon Bertrand Gurdon, professor of the Zoology Department of the University of Cambridge, admitted of feeling extremely honored for such a spectacular privilege.

Moreover, Shinya Yamanaka discovered the so called induced pluripotent stem cells (iPS), which have the same proprieties of the embryonic ones and are able to turn into whatever other type of body cell. He asserted that he will continue to conduct research in order to contribute to society and medicine. For him that is a duty.

Yamanaka created four types of genes that supply cells with their pluripotentiality, in other words, the same capacity that embryonic stem cells have. If implanted in differentiated cells, for example of skin, they become pluripotent stem cells. The iPS supply a vast amount of plasticity just as embryonic stem cells do, however, without requiring the extermination or cloning of human embryos, since the initial cells can be obtained from the same patient. In this aspect, these cells have the same status as adult stem cells do, with the advantage of their versatility.

The dilema that has been stirred by the iPS is being resolved due to recent studies carried out by Leisuke Kaji (Universidad de Edimburgo) and Andreas Nagy (Samuel Lunenfeld Research Institute of Mount Sinai Hospital of Toronto).

The created iPS perennially retain their pluripotentiality. There is still the need of research to be conducted concerning the control of the difference between these cells in order for them to create the tissue that is necessary for each case. As Kaji affirms in The Guardian, it is a step towards the practical use of reprogrammed cells in the field of medicine, which could eventually lead to eliminating the need of counting on human embryos as the main source of stem cells.

Hurray for Gurdon and Yamanaka, Nobel Prize Winners for Pro-life Medicine - Gilmer Mirror

IPS Cell Therapy Comments Off on Hurray for Gurdon and Yamanaka, Nobel Prize Winners for Pro-life Medicine – Gilmer Mirror | June 30th, 2017

A regenerative medicine startup led by a Mayo Clinic cardiologist is setting up shop in a downtown Rochesters Minnesota BioBusiness Center, according to newly filed city documents. The filing indicated Rion LLC, a Minnesota company registered to Dr. Atta Behfar of the Mayo Clinic Center for Regenerative Medicine, has signed a three-year lease for just over 2,000 square feet at the city-owned BioBusiness Center. The lease begins July 1. The nine-story BioBusiness Center opened in downtown Rochester in 2007 as a center for innovation in biotechnology, promoting the linkages between the researchers and practitioners at Mayo Clinic; instructors and students at the University of Minnesota Rochester, and the biotechnology business community. It houses the Mayo Clinic Business Accelerator among other tenants. Behfar is an assistant medical professor and leads a laboratory at Mayo concentrating on applying regenerative medicine the practice of using stem cells to regenerate damaged or missing tissue to prevent and cure chronic heart conditions. Specifically, his group focuses on development and use of both stem cells and protein-based therapies to reverse injury caused by lack of blood flow to the heart. The business direction of Rion, meanwhile, appears to be specifically geared toward a cutting-edge development in the field of regenerative medicine the use of extracellular vesicles (EVs) in speeding and directing the growth of regenerating tissues in the heart and elsewhere in the body. EVs, long brushed off by researchers as mere debris in the bloodstream, are membrane-enclosed spheres that break off from the surfaces of nearly all living cells when disturbed. They transport lipids, proteins and nucleic acids, and have now been found to be important players in cell-to-cell communication, influencing the behavior and even the identity of cells. Their emerging role in regenerative medicine could potentially be huge. For instance, by bioengineering them to transport protein payloads from stem cells, they can be used to signal the bodys own cells to regenerate tissue instead of transplanting the stem cells themselves, thus eliminating the chance of host immune system rejection. A patent application filed last year by Rion, Behfar, Mayo Center for Regenerative Medicine Director Dr. Andre Terzic and two other local inventors is aimed at adapting the healing properties of a specific type of EV into a unique kind of product that could have wide applications. It focuses on EVs derived from blood platelets, which are well known to stop bleeding, promote the growth of new tissues and blood vessels, relieve inflammation and provide a host of other benefits. The patent describes a system of encapsulating platelet EVs derived from human or animal blood into a platelet honey and delivering it to target areas of the body, such as damaged tissues or organs. Its purported effect is to regenerate, repair and restore damaged tissue, with possible uses including treating heart disease; healing damaged bones or joints; wound treatment; and cosmetic skin applications. A brief business description provided by Rion to Rochester city officials stated the company is focused on the delivery of cutting edge regenerative technologies to patients at low cost and in off-the-shelf fashion. Building on initial research at Mayo Clinic, Rion LLC aims to develop and bring to practice products in the space of wound healing, orthopedics and cardiac disease. The statement also added the company is an enthusiastic backer of Rochesters efforts to develop a local biotech business cluster, and is seeking to participate in the realization of the Destination Medical Center initiative.

Free Press Lions beat writer Dave Birkett answers your Twitter questions in a video mailbag June 26, 2017, before summer vacation.

Paul Worrilow has a great back story.

The veteran linebacker, who signed with the Lions in March, was undrafted out of Delaware.

He made the Atlanta Falcons, against all odds.

Cracked the starting lineup, against all odds.

Became the teams leading tackler, against all odds.

Stuck around for four seasons, against all odds.

But theres more.

Its a story about being selfless and thinking about others. Its a story that should be repeated, if only to inspire others to follow his lead.

And it started with a simple cheek swab.

Its so simple, Worrilow said.

When Worrilow was a sophomore at Delaware, he joined the Be The Match Foundation Registry, hoping to become a bone marrow donor.

Four months later, he was matched with a 23-year-old woman with leukemia.

Worrilow donated peripheral blood stem cells to the woman, although he doesnt know what happened to her. He doesnt know her name. He never has met her.

Its so simple, Worrilow said. They do a cheek swab. You get put in the database. If you match somebody, there are two ways to do it. You can donate actual bone marrow or do it like I did, peripheral blood stem cells.

About one in 40 registry members will be called for additional testing.

About one in 300 will be selected as the best possible donor for a patient.

And about one in 430 on the registry go on to donate bone marrow or peripheral blood stem cells.

Odds are, you never will be asked to donate.

But you just might give somebody hope.

Its so simple, Worrilow said. Its not painful. Its a small part of your time, to have a great impact, a tremendous impact on another person and their family. Its a no-brainer. You can have a great impact at such a small cost to yourself.

Worrilow is on a mission to let people know about it: The cool part about it is being able to share it (with people) who are ignorant to the process and their ability to help other people. Encouraging people. People who just dont know what Be The Match Foundation is. Or how you can help people with blood cancers, or how you can join.

Worrilow signed with the Lions during the off-season.

This team is tremendous, Worrilow said. The family-oriented vibe here. From the head coach, from the ownership on down, you can feel it. Its a family vibe. They look after you, care for you.

In June, during minicamp, Worrilow played weak-side linebacker. But he can also play in the middle.

Its going good, he said. There is a lot of competition. The team is great that way, pushing each other. Any action I can get on the field is exciting. When youre winning games, and everyones in here practicing hard, its just awesome.

Worrilow has a track record for good tackling, but he has been criticized for his inability to cover.

If (the criticism) is there, its probably there for a reason, he said. Criticism, if it doesnt come from a bad place, it is probably warranted. And thats something I have to improve on. Thats with all parts of my game. I dont feel like I have played my best football yet.

Worrilow said he is adjusting to the Lions defense, making defensive calls.

Compared to the other places Ive played, there is a bigger volume of calls, he said. Thats something I like. Both linebackers do it. One guy has the indicator, but if you are not out there talking, you arent going to be out there.

And now, as he takes time off before training camp, he feels confident about himself and this team.

I dont feel like I could be in a better place, life-wise, work-wise, everything, he said. Its an encouraging place to come in and work every day. The linebacker group is awesome. Its young. Its competitive. Thats what you want.

So, this guy keeps breaking the odds.

Sticking in the NFL. And trying to use that platform to help others.

Trying to raise awareness.

Trying to encourage people to make a difference.

Trying to break the odds.

Detroit Lions' Paul Worrilow has beaten odds, inspires others to help - Detroit Free Press

Bone Marrow Stem Cells Comments Off on Detroit Lions’ Paul Worrilow has beaten odds, inspires others to help – Detroit Free Press | June 29th, 2017

AVERY Beal has seen more suffering in her three short years than many people see in a lifetime.

The plucky toddler was diagnosed with Acute Lymphoblastic Leukaemia in August 2014 and has been fighting for her life ever since.

In the last three years, she has lived through chemotherapy, stem cell transplants, and bone marrow transplants.

It's been a rough few years on the rest of the family too.

Avery's mum Jen has spent the last two and a half years living in between the Beal family home on the Sunshine Coast and Lady Cilento's Children Hospital in Brisbane to care for Avery's medical needs.

Dad David has cared for the couple's other five children on the Coast, working to support them while home schooling their autistic twins.

To top it all off, Mr Beal said the family was recently given no choice but to move house after their lease ended.

Despite the tumultuous last few years, the ordeal might finally be over for Avery - although she's still very high risk, doctors have deemed her well enough to come home.

"Avery's been doing really good," Mr Beal said.

"She managed to get transplant stem cells from a baby's (umbilical) cord from another country.

"She managed to get to day 100 after the transplant, which at that stage doctors were happy for Jen and Avery to come home."

Avery had a second bone marrow transplant in March after her first one failed to stimulate Avery's blood cells to create healthy cells instead of cancerous ones.

"We're feeling good but the challenge is that she's still so high risk," Mr Beal said.

"With children, they'll generally speaking only do two bone marrow transplants.

"If it does come back there is literally nothing they can do. They would just make her comfortable.

"At the moment, we have tests done on her bone marrow every month so see that she's still cancer free."

Yesterday Avery had her central line - a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood transfusions -removed for the first time since her diagnosis in 2014.

The bubbly three-year-old will finally be able to go swimming - an experience that Avery has missed out on living on the Sunshine Coast.

Although the spritely tot has an 85% chance of relapsing, the family are confident that this is a good sign.

Despite all life has thrown at her, Avery is a happy child that lights up the lives of those around her.

"She's just incredible," Mr Beal said.

"It just amazes me over and over again how amazing she is on top of the treatments and the drugs; I think she's on eight different meds every morning and evening."

Mr Beal said the biggest hurdle the family currently face is the cost of Avery's multiple medications.

"She had a number on different things to get her body to a place for the transplant she's had in march," he said.

"Since then she's been on lots of different meds to make sure her body doesn't reject the transplant.

"For us finances are the biggest thing.

"Now that Avery is out of hospital we have to pay for medication and Jen's still having to do trips to Brisbane every week or fortnight"

Glimmer of hope in Avery's heartbreaking cancer battle - The Sunshine Coast Daily

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.

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

According to Fiona (49), 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.
