Nnew genetic method developed to pinpoint individuals' geographic origin

ScienceDaily (May 24, 2012) Understanding the genetic diversity within and between populations has important implications for studies of human disease and evolution. This includes identifying associations between genetic variants and disease, detecting genomic regions that have undergone positive selection and highlighting interesting aspects of human population history.

Now, a team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science, UCLA's Department of Ecology and Evolutionary Biology and Israel's Tel Aviv University has developed an innovative approach to the study of genetic diversity called spatial ancestry analysis (SPA), which allows for the modeling of genetic variation in two- or three-dimensional space.

Their study is published online this week in the journal Nature Genetics.

With SPA, researchers can model the spatial distribution of each genetic variant by assigning a genetic variant's frequency as a continuous function in geographic space. By doing this, they show that the explicit modeling of the genetic variant frequency -- the proportion of individuals who carry a specific variant -- allows individuals to be localized on a world map on the basis of their genetic information alone.

"If we know from where each individual in our study originated, what we observe is that some variation is more common in one part of the world and less common in another part of the world," said Eleazar Eskin, an associate professor of computer science at UCLA Engineering. "How common these variants are in a specific location changes gradually as the location changes.

"In this study, we think of the frequency of variation as being defined by a specific location. This gives us a different way to think about populations, which are usually thought of as being discrete. Instead, we think about the variant frequencies changing in different locations. If you think about a person's ancestry, it is no longer about being from a specific population -- but instead, each person's ancestry is defined by the location they're from. Now ancestry is a continuum."

The team reports the development of a simple probabilistic model for the spatial structure of genetic variation, with which they model how the frequency of each genetic variant changes as a function of the location of the individual in geographic space (where the gene frequency is actually a function of the x and y coordinates of an individual on a map).

"If the location of an individual is unknown, our model can actually infer geographic origins for each individual using only their genetic data with surprising accuracy," said Wen-Yun Yang, a UCLA computer science graduate student.

"The model makes it possible to infer the geographic ancestry of an individual's parents, even if those parents differ in ancestry. Existing approaches falter when it comes to this task," said UCLA's John Novembre, an assistant professor in the department of ecology and evolution.

SPA is also able to model genetic variation on a globe.

Gene therapy can correct forms of severe combined immunodeficiency, study suggests

ScienceDaily (May 24, 2012) Severe combined immunodeficiency is defect in the immune system that results in a loss of the adaptive immune cells known as B cells and T cells. Mutations in several different genes can lead to the development of severe combined immunodeficiency, including mutation of the adenosine deaminase (ADA) gene. Traditional treatment options, such as enzyme replacement therapy, are of limited efficacy, but bone marrow transplant from a compatible donor leads to a better response.

A recent clinical trial indicated that gene therapy to insert the correct ADA gene in the patient's own bone marrow cells can also lead to a good response.

However, patients were noted to have defects in B cell tolerance, meaning that some B cells that react to antigens from the body fail to be eliminated, leading to an autoimmune response. Dr. Eric Meffre and colleages at Yale University in New Haven, Connecticut and Alessandro Aiuti in Milan, Italy joined together to better understand why patients developed B cell tolerance problems. They found that loss of the ADA gene directly contributes to B cell tolerance problems and that these defects are mostly corrected after gene therapy.

Their results point to a previously unknown role for ADA in B cell response and support the use of gene therapy as an effective treatment option for ADA-deficient severe combined immunodeficiency patients.

Men In Black 3

Josh Brolin is badass as young K.

Back in 1997, Men In Black felt like state-of-the-moment entertainment with self-consciously hip, retro-futurism encoded in it's DNA. A decade and a half later the sagging brand gets a jumpstart via the dependable sequel orthodoxy of a time-travel plotline, one that pays tribute not just to the swinging '60s, but to the '80s heyday of big, silly sci-fi action comedies.

Agents J (Will Smith) and Agent K (Jones) are back in black, still busting up intergalactic perps by day and living lonely, near monastic lifestyles off the clock. When your co-workers are the most significant human interactions, you tend to get pretty attached, and J has grown rather fond of his partner K even though the irascible old coot is an emotional wasteland. Jones' craggy, wrinkled mug has a real world-weariness to it and his performance has taken on the hangdog comedic dimensions of a Droopy cartoon. Smith is his animated self, and here he gets not one, but two deadpan partners to bounce his eternally boyish charms off of. An interstellar lunatic called Boris the Animal (Jemaine Clement) escapes his max-security lunar prison, and makes good on his vow of revenge against K, by traveling back to his capture in 1969 and erasing his nemesis from the timeline and setting the stage for an alien invasion. MIB's new boss Emma Thompson (Rip Torn gets hastily killed off) figures out the scheme, and J dutifully charges to the rescue of his mentor using a high tech gizmo to plunge back to the era of mini-skirts, hippies and gas guzzling Detroit built roadsters, and still blatant racism.

The plot ensures that Jones had an easy shooting schedule, but he's ably replaced by Josh Brolin, who does a dead-on Tommy Lee impression: nailing the actor's laconic Texas drawl with the same precision he used to mock George W. Bush. The younger agent K is still a badass, but not nearly as flinty or cold, and we are continually teased that some upcoming trauma hardened his heart. This subplot lends some humanity to what would otherwise be a gimmick-laden whirl of CGI sparkles, and the easy chemistry and effortless agility of the stars keeps things buzzing.

Director Barry Sonnenfeld is as over-caffeinated as ever. His frenetic tone changes between comedy, action and pathos are quick enough to induce whiplash. Despite the spastic pace, the movie feels a little sluggish out of the gate, and only really hits its stride when Brolin hits the screen.

Flight of the Conchords cutup Jemaine Clement is buried under shark-like teeth, Klingon hair and thick goggles, and his villain is more goofy than menacing with his absurd vocal inflection somewhere between David Bowie and James Earl Jones. He's just a distraction in a flick filled with gags about bulky mid-century tech and weirdo mod icons like Mick Jagger and Andy Warhol being from outer space. The script is credited to no less than five writers, and feels patched together due to time-travel conundrums and some shaky math, which leaves certain actors not looking right for their character's presumed ages.

Faith Leaders Outline Religious Freedom Threats

Leaders from a variety of faith backgrounds, politicians and educators met Thursday in Washington, D.C., for the National Religious Freedom Conference: Rising Threats to Religious Freedom, an event that organizers say is part of a battle against the trampling of religious liberties in the public sphere.

"This debate is not just about contraceptives, but about coercion. It's not about Catholics it's about conscience," Richard Land, president of the Ethics & Religious Liberty Commission of the Southern Baptist Convention said during one of the panel discussions. He went on to say, "it's about principle, not pelvic politics."

Former Utah Gov. Michael Levitt, also a former Health and Human Services secretary, said of the conference, "This is the uniting of the faith community to declare that we're going to fight back to defend religious freedom."

The conference outlined three major threats to religious freedom: The first is the government mandate that religious institutions, such as hospitals and universities, act contrary to their conscience by offering birth control coverage to their employees. The second is what religious leaders say is a threat to the autonomy of religious organizations to choose their own leaders.

The third issue, a key one, is religious principles in in everyday life, like pharmacists who object for moral reasons to carrying what believers equate to abortion-causing drugsor religious student groups being marginalized on school campuses. One example of the latter is the fight at Vanderbilt University over its non-discrimination policy, requiring student religious groups be open to anyone, even those who don't hold to their beliefs.

Conference participants see a prejudice that affects all religions.

"We need to find a way to bridge not only the faith divide but also the political divide to try to find a way where everybody can enjoy religious liberty," Nathan Diament, director of public policy for the Union of Orthodox Jewish Congregations, said. "It doesn't have to be a zero sum game. Some people's rights do not have to come at the expense of other peoples rights. We can find a way to make it a win-win situation for everybody."

The conference comes in the wake of a federal lawsuit filed by more than 40 Catholic institutions over the health care law that mandates the church offer institutional employees contraceptive coverage and other benefits that go against Catholic teaching. Churches already are exempt from the mandate.

Cardinal Timothy Dolan said the church is pushing forward, looking at all options.

"We are not going to give up dialogue with them. Who knows, maybe the lawsuits will make some progress, but so far we haven't seen any mitigation. Mitigation that the administration offered us back in February didn't help us much, because we are self-insured and it didn't touch those straight-jacketing exemptions."

Guerrieri claims checkered flag in Freedom 100

INDIANAPOLIS (AP) -- A bold move late in the Freedom 100 gave Esteban Guerrieri the lead and the Argentine held on to win a crash-marred Indy Lights race Friday in Indianapolis.

The developmental series race was largely run in packs and included a wild early melee that brought out a red flag, stopping the race because of damage to a barrier. Another hard hit late in the race brought out a yellow that did not give rookie Carlos Munoz a chance to catch Guerrieri.

It's the fourth consecutive year Sam Schmidt Motorsports has won the Freedom 100. France's Tristan Vautier, another rookie, was third behind Munoz.

Four drivers went to the infield medical center, including Emerson Newton-John, the nephew of singer Olivia Newton-John. All were cleared and released.

Guest Post: Keynesianism & Eugenics

The theory of output as a whole, which is what The General Theory of Employment, Interest and Money purports to provide, is much more easily adapted to the conditions of a totalitarian state. John Maynard Keynes

In looking at and assessing the economic paradigm of John Maynard Keynes a man himself fixated on aggregates we must look at the aggregate of his thought, and the aggregate of his ideology.

Keynes was not just an economist. Between 1937 and 1944 he served as the head of the Eugenics Society and once called eugenicsthe most important, significant and, I would add, genuine branch of sociology which exists. And Keynes, we should add, understood that economics was a branch of sociology. So lets be clear: Keynes thought eugenics was more important, more significant, and more genuine than economics.

Eugenics or the control of reproduction is a very old idea.

In The Republic, Plato advocated that the state should covertly control human reproduction:

You have in your house hunting-dogs and a number of pedigree cocks. Do not some prove better than the rest?Do you then breed from all indiscriminately, or are you careful to breed from the best?And, again, do you breed from the youngest or the oldest, or, so far as may be, from those in their prime? And if they are not thus bred, you expect, do you not, that your birds and hounds will greatly degenerate? And what of horses and other animals? Is it otherwise with them? How imperative, then, is our need of the highest skill in our rulers, if the principle holds also for mankind? The best men must cohabit with the best women in as many cases as possible and the worst with the worst in the fewest,and that the offspring of the one must be reared and that of the other not, if the flock is to be as perfect as possible. And the way in which all this is brought to pass must be unknown to any but the rulers, if, again, the herd of guardians is to be as free as possible from dissension. Certain ingenious lots, then, I suppose, must be devised so that the inferior man at each conjugation may blame chance and not the rulers and on the young men, surely, who excel in war and other pursuits we must bestow honors and prizes, and, in particular, the opportunity of more frequent intercourse with the women, which will at the same time be a plausible pretext for having them beget as many of the children as possible. And the children thus born will be taken over by the officials appointed for this.

Additionally, Plato advocated disposing with the offspring of the inferior:

The offspring of the inferior, and any of those of the other sort who are born defective, they will properly dispose of in secret, so that no one will know what has become of them. That is the condition of preserving the purity of the guardians breed.

In modernity, the idea appears to have reappeared in the work first of Thomas Malthus, and later that of Francis Galton.

Gary Oldman signs up for Robocop remake

Gary Oldman has signed up for the 'RoboCop' remake.

The 'Tinker Tailor Soldier Spy' actor will star as Norton, a scientist who creates the technology that brings the titular super-human cyborg who is played by Joel Kinnaman - to life in the MGM reboot of the 1987 sci-fi movie.

But Gary's alter-ego will find himself torn between a callous company and the machine who was formerly a police officer called Alex Murphy saved from the brink of death and turned into a robot cop - trying to rediscover his humanity, according to The Hollywood Reporter.

Jose Padilha will direct the motion picture, with Marc Abraham and Eric Newman in line to produce.

The filmmaker had previously revealed Michael Fassbender was his top choice to play the cyborg who was originally portrayed by Peter Weller in the first two 'Robocop' movies in 1987 and 1990 before Robert Burke took over in 1993's 'Robocop 3' - and the 'Shame' actor even signalled his interest about starring in the project.

Jose said: "I can't talk yet, it's too early to speak, but there are some actors I like. I really like the Fassbender, I'd like to talk to him - I'll talk to him. There's a possibility ...."

Michael explained: "You know, I'm always open. I'll take a look at the script and sit down with the director and have a conversation. It's not definitely like, 'Oh, I've got to play RoboCop before I retire.' I don't have that about anything. I don't go, 'I have to play the Dane one day, or Hamlet.' I don't really think like that.

"I just wait and see what comes up, and I'm always open to it. If I react to the script, then I'm up for anything.

"It could be kind of fun [to wear the iconic outfit]. It could be kind of good to have a helmet that I could hide behind for most of the film too, that sounds kind of appealing."

Broward, Palm Beach County beaches not nationally acclaimed (again)

For yet another year, beaches in Broward and Palm Beach counties have failed to make the Top 10 list published by the South Florida professor known as Dr. Beach.

The latest ranking, issued Friday, proclaimed Coronado Beach, across the bay from San Diego, Calif., as America's best. It also continued a bleak trend for coastal Broward and Palm Beach counties. For 22 years, no stretch of local shoreline has ever made the Top 10.

So what's the problem?

"There are 650 beaches [analyzed] in the country, it's very hard to make that top 10 list," said Stephen P. Leatherman, director of Florida International University's Laboratory for Coastal Research, also known as "Dr. Beach."

Still, "you've got a list of very nice beaches" in the two counties that he has ranked in the "20s and 30s," Leatherman said.

Dr. Beach rates beaches using 50 criteria, including sand and water quality, weather, facilities, safety, environmental management and crowds. He visits top 10 candidates incognito to collect sand and water samples for study.

He does have his favorites here, such as Pompano Beach.

"I really like that beach," Leatherman said. "But there is no perfect beach; I haven't found a perfect beach."

Other places have no shot at being included in his hit parade.

"I like Hollywood, but there's too much development on the beach, that's not going to be on the Top 10 list," he said. Dr. Beach likes some amenities, but not too many. "People are looking for some creature comforts. I'm looking for that balance. There are some in Boca that have potential. That's what I'm looking for," he said.

Africa is indeed rising – Zuma

President Jacob Zuma congratulated Science and Technology Minister Naledi Pandor and her team on Friday for winning the right to co-host the Square Kilometre Array (SKA) telescope with Australia.

"We are especially proud of winning this bid... on Africa Day," Zuma said in a statement.

"Africa is indeed rising. South Africa is confident that the country will deliver on the expectations of the continent and world."

Zuma said the this achievement was possible because of the African Union's endorsement and support from partner countries including Botswana, Ghana, Kenya, Madagascar, Mauritius, Namibia and Zambia.

Earlier, it was announced that the SKA board had decided on a "dual site approach".

"We will be installing equipment in both Australia and South Africa and together they will form part of a global observatory," the French news agency AFP quoted SKA board chairperson John Womersley as saying at a press conference at the Schiphol Airport, in Amsterdam.

"This is a momentous day for South Africa and the continent and will give all of us the possibility to answer fundamental questions in physics, astronomy and cosmology," the African National Congress said.

"It will advance our scientific research capacity as a country and a continent and will also see a lot of foreign direct investment injected into this project, which will go a long way in creating much-needed jobs..."

The ANC said it would also put South Africa in good stead to advance to an inclusive information society.

Democratic Alliance MP Junita Kloppers-Lourens said the party was disheartened, but not dismayed at the decision.

Nanotechnology for solar energy conversion systems

EU researchers extensively characterised the self-organisation of nanotubes and developed novel compositions particularly appropriate to solar energy conversion applications.

Self-organized one-dimensional (1D) oxide nanotube systems are a hot research topic of late given that their inherently high surface area-to-volume ratio produces interesting and useful properties.

In particular, over the last 20 years, ordered arrays of porous titanium oxide (TiO2), or TiO2 nanotubes, achieved via electrochemical anodisation have been extensively studied. To date, TiO2 is the only material suitable for use as a photocatalyst (substance using light energy to enhance chemical reactions) due to its high efficiency and stability, low cost and safety profile toward humans and the environment.

European researchers set out to prepare and characterise self-organised TiO2 nanotubes with an ordered structure similar to that of porous aluminium oxide (Al2O3) and silicon (Si) nanotubes via funding of the Preparation, characterisation and application of self-organised titanium oxide - nanotubes (TI- Nanotubes) project.

In particular, investigators sought to understand key parameters governing self-organisation of TiO2 nanotubes, specifically those affecting tube dimensions, orientation and morphology. The ultimate goal was to develop novel functional and structural materials with superior performance characteristics to be used in solar energy conversion systems such as dye-sensitised solar cells.

Self-ordering mechanisms of TiO2 nanotubes were investigated via a plethora of surface analysis technologies including Rutherford backscattering spectrometry (RBS) and nuclear reaction analysis (NRA) for depth profiling.

The TI- Nanotubes consortium successfully produced TiO2 nanotube arrays doped with silver (Ag) or iron (Fe) that exhibited enhanced photocatalytic activity important for solar energy conversion applications.

Commercial exploitation of TI- Nanotubes project results has the potential to enhance solar energy efficiency and use with important benefits for the EU economy, EU citizens and the planet.

Dr. John P. Naughton, UB medical school dean

May 20, 1933May 21, 2012

Dr. John P. Naughton, the longest-serving dean in the history of the University at Buffalo School of Medicine and Biomedical Sciences, died Monday in his Cheektowaga home.

The internationally known cardiologist, who served as dean for 21 years and was UBs vice president for clinical affairs for the last 12 of those years, was 79.

A native of Nanticoke, Pa., he graduated from St. Louis University and earned his medical degree from the University of Oklahoma College of Medicine.

Dr. Naughton never forgot the lessons he learned while observing a family doctor in a small Oklahoma town during a rotation in medical school.

He tried to create a medical school that would train students to provide the kind of patient- centered care he saw there, said his longtime colleague, Dr. Thomas C. Rosenthal, chairman of UBs department of family medicine.

Dr. Naughton joined the UB faculty in 1975 as dean and professor of medicine, according to a biography provided by the university.

He previously had served as professor of medicine and dean for academic affairs at the George Washington University School of Medicine and Health Sciences.

Dr. Naughton was considered an expert in the field of exercise and physical activity and in the prevention of coronary heart disease.

He developed the Naughton Treadmill Protocol, the first protocol used for exercise stress tests.

KMC proposes $35 million deal with Caribbean medical school

In an unusual arrangement that was described as benefiting both institutions, a for-profit Caribbean medical school has offered Kern Medical Center $35 million over 10 years for nearly exclusive rights to have its students rotate through the county facility.

For the financially struggling country hospital, the money would help improve its medical student program and overall academic mission, said CEO Paul Hensler.

The students, most of whom will be U.S. born, will come from Ross University, located on the Caribbean island of Dominica. Only 29 miles wide and 16 miles long, Dominica lies at the top of the Windward Islands in the West Indies.

The move benefits Ross by securing coveted medical school rotation spots in California, a region that has not offered as many opportunities for offshore schools.

The arrangement needs the approval of the Kern County Board of Supervisors, which will consider the matter on Tuesday. It may raise questions because Caribbean schools have a reputation for attracting Americans who can't get into U.S. medical schools.

Medical students typically spend their first two years on basic science coursework and the last two years in clinical rotations. U.S. schools often have affiliated hospitals where students can do those rotations, without having to pay additional costs.

Most Caribbean schools have no nearby associated hospitals, so they must seek out U.S. teaching hospitals willing to host their students.

KMC already receives about $750,000 per year from a variety of Caribbean schools in exchange for hosting about 100 rotation slots for med students. They also get a handful of students from UCLA, which, like other American medical schools, does not pay for the opportunity.

Medical students observe and participate in clinical care under the supervision of a faculty member or resident. Residents, on the other hand, already are licensed doctors, and are in the process of training in a particular speciality, such as family medicine.

If the KMC proposal is approved, Ross will be given priority for those slots. UCLA students will still be allowed to come, as well as students from other offshore schools with Kern County connections.

Are medical schools squashing creativity? Part 2: Lighten up on mandates, and take advantage of the informal curriculum

A few weeks ago, I wrote about creativity. With its emphasis onrequirements and contrived benchmarks of success, medical school admissions might inadvertently be selecting for those who are skilled at jumping through hoops and weeding out more independent thinkers. I received comments from people who were so inspired that they wanted to discuss ideas about reforming the curriculum. Creativity is missing; how are we going to fix this? It was the epitome of irony to me: attempting to standardize the exact thing that refers to thinking outside standardization.

In this post, I hope to address my thinking about the subject in a bit more detail. I believe excessive curriculum mandates are a well-meaning but counterproductive approach to solving what we are aiming to solve.

The temptation to improve education through mandates is not new. Every few years, medical administrators, politicians, or some other Powers That Be decide an important quality that all doctors should have is not being taught, and that it must be standardized into medical education. Focus was first on mastery of the hard sciences, then turned to increased emphasis on compassion and communication. The latest has been a turn to the medical humanities, with endeavors such as visiting art museums and engaging in poetry-writing sessions becoming increasingly widespread. At the end of 2011, 69 of 133 accredited medical schools in the US required a course in the medical humanities.

Medicine is holistic a blend of science and art which those inclined to suggest reform rightly realize involves far more than repairing the human body when it malfunctions. The medical humanities, as a field of study, is invaluable. The question is: should it be required?

Fourth-year medical student Rhys Davies has reservations: Asking students to compare the role of literature in sickness between Broyard and Mantel is pointless unless they want to get something out of it, he writes. In fact, he says, its because he cares so much about the medical humanities (he is completing a thesis in it) that he opposes its obligatory presence in the curriculum. The setup is bad for everyone. Those not interested are miserable, and those who are have a mediocre experience tainted by the heel-dragging of their peers. As Davies puts it, Anything compulsory is duly attended but interest is notably absent.

That is not to say there is no worth in a well-rounded curriculum. There is value in exposing students to diverse ideas and activities, perhaps sparking new passions that never would have been discovered otherwise. There is something to be said for making students do things considered good for them. Mandate nothing, and people might not learn enough. Some need that extra push. They might gripe along the way, but then say after, Im really glad I did that.

But place too much emphasis on curriculum, and the downside is exacerbating a culture of excessive busywork at the expense of some of the most meaningful ways of learning. The knee-jerk desire to reform curriculum whenever a desirable skillset is identified is based on a particular assumption: that every skill is best learned through the medium of coursework. Unfortunately, that assumption just isnt true.

There is a wonderful ethics professor here at Harvard, Dr. Edward Hundert, who has written a lot about the informal curriculum of medical school. A significant transmission of culture happens outside classes, hospital rounds, and the like, he says, over meals or during carpool rides from remote clinical sites. From focus groups with students, he found that the vast majority of the situations the students described as most influential were conversations with no faculty present. He concluded: I have discovered just how little a role the formal ethics curriculum plays in the moral and professional development of our students and residents. We succumb to the mistake of emphasizing teaching, when what we really ought to focus on is learning.

That can occur in many ways. Dr. Faith T. Fitzgerald, former dean of students at the University of California, Davis, School of Medicine, understands this well. She boldlychallenged a request from politicians that more humanities coursework be added to the medical curriculum, explaining:[I was concerned that] the addition of required courses in literature, drama, sociology, music, and art might actually limit students opportunities to read, go to the theater, be with friends and family, and attend a symphony or museum. Even if they would not have done these things, she continued, the additional coursework would cut down on contemplative time, volunteerism in free clinics, hobbies, and sleep.

Requirements come withan inherent trade-off. With the medical part of medical school demanding enough, free time is a commodity. Soak up our time with mandates aimed to make us well-rounded people, and we have less time to actually do the things, outside the narrow confines of a formalized curriculum, that make us well-rounded people.

Biostem U.S., Corporation Announces $5,000,000 Financing Agreement Through Private Placement of Stock

CLEARWATER, FL--(Marketwire -05/24/12)- Biostem U.S., Corporation, (HAIR.PK) (HAIR.PK) (Biostem, the Company), a fully reporting public company in the stem cell regenerative medicine sciences sector, announces a $5,000,000 financing agreement through private placement of stock.

CEO, Dwight Brunoehler, announced today that the company has signed an agreement with a funder to issue 20,000,000 shares of the company's common stock in exchange for $5,000,000 in cash or 25 cents ($.25) per share. No other considerations will be granted to the funder in exchange for the cash payment.

In announcing the funding agreement, Mr. Brunoehler commented, "We consider the eagerness of the funder to acquire Biostem shares at a price above the current market to be a tribute to our proven proprietary technology to enhance hair re-growth using human stem cells. Although we anticipated funding the company through the sale of a convertible debenture, the funder insisted on being able to acquire stock at a set price now, rather than risk having to convert at higher prices later. Although Rule 144 sale restrictions usually cause private placements of stock to be executed at a discount to the market, Biostem feels that its current share price is not truly reflective of the value of its proprietary technology; as well as the fact that the technology is already being employed, and the overall size of the hair replacement marketplace. It was for this reason that the company and the funder were able to come to an agreement to price the private placement above the current share price."
