When it comes to developmental disorders of the brain, men and women are not created equal.

Decades of research have shown that males are at far greater risk for neurodevelopmental disorders such as autism spectrum disorder (ASD) than females. Boys, on average, are five times more likely to have autismthan girls.What causes this disparity has largely remained unknown.

Now scientists haveuncovered compelling genetic evidence to explain why the biological scales arent balanced.

According to a team of geneticists in the U.S. and Switzerland,it all boils down to whats called the female protective model. This suggests that girls have a higher tolerance for harmful genetic mutations and therefore require a larger number ofthem than boys to reach the diagnostic threshold of a developmental disorder. With identical genetic mutations, then, a boy could show symptoms of ASD while a girl could show none.

But because the female mutation threshold is higher, when girls are diagnosed with ASD, they tend to fall on the more severe end of the spectrum.

Researchers believe the same dynamic could explain why more boys are diagnosed withADHD, intellectual disabilities and schizophrenia. The findings were published Thursday in the American Journal of Human Genetics.

Geneticists analyzed DNA samples from 16,000 boys and girls with neurodevelopmental disorders.They found that, on average, females diagnosed with ASD had 1.3 to 3 times more harmful genetic alterations than males diagnosed with the disorder.

The findings suggest that as the male brain develops, smaller and more subtle genetic changes can trigger autism spectrum disorders. Female brains require a greater number or severity of mutations before showing symptoms, so their symptoms tend to be worse.

Theres no application in terms of treatment, said study author Sbastien Jacquemont of University Hospital of Lausanne in Switzerland, but it does help understand the inheritance dynamics in families.

A LOCAL man on Tuesday celebrated his 39th birthday by becoming Shanghais 294th hematopoietic stem cell donor after shedding 22 kilograms to meet the eligibility requirements.

Pan Weizhong, a team leader for Sinopec, joined the China Bone Marrow Bank in 2007 after one of his colleagues successfully donated his stem cells. Last October, Pan received a call from the Shanghai Red Cross Society telling him his blood was a match for a 28-year-old woman suffering from leukemia in Wuhan, capital of central Chinas Hubei Province.

He was really excited when he found out and couldnt wait to tell me when I came home from work,Pans wife Wang Aiping, who works as an accountant at a community health care center, told Shanghai Daily yesterday.

I was also very happy because I had always supported his decision to become a donor.

But when Pan, who weighed about 90 kilograms at the time, went for a preliminary medical examination, doctors told him he had a fatty liver and needed to lose weight, Wang said.

Determined to qualify for the scheme, Pan switched to a vegetarian diet and began exercising for two hours every day. He even quit smoking and drinking alcohol, his wife said.

My son and I also became vegetarians to support him,she said.

After two months of no meat and lots of exercise, doctors gave Pan the green light.

After Tuesdays operation Pan said he was delighted to have been able to help someone he had never even met.

It feels great to celebrate my birthday by giving this woman a fresh start in life,he said.Its the best present Ive ever had.

Scientists have transformed human skin cells into fully functioning liver cells with "extremely promising" therapeutic potential.

Transplanted into laboratory mice with liver failure, the cells matured and multiplied over a period of nine months.

In future they could form the basis of personalised treatments for patients who might otherwise need a liver transplant.

Earlier attempts to produce liver cells from artificially created stem cells have proved disappointing.

Generally, once implanted into existing liver tissue the cells have not tended to survive.

The new research involved a two-stage process of transforming skin cells in the laboratory before transplanting them.

First, the cells were genetically reprogrammed back to an intermediate "endoderm" stage of development using a cocktail of genes and chemical compounds.

Story continues below the slideshow:

"The liver likes a balanced diet, just like the rest of your body," explains Dr. Nancy Reau, vice president of the American Liver Foundation's Board of Directors. She notes that an extreme elimination diet is generally not good for your system, and any benefit it may give you disappears once you go back to eating regularly. For the liver (as well as the rest of your body), look to high-fibre vegetables and lean proteins.

Adler Footcare of Greater New York is offering an advanced treatment option for chronic foot problems like plantar fasciitis, as well as common foot problems like Osteoarthritis, Achilles tendonitis and torn soft tissue.

In the past these conditions have been treated by physical therapy or orthotic therapy, but the results have often been poor, leaving patients continuing to struggle with the pain. With stem cell replacement therapy, the treatment of these conditions is proving far more effective and long lasting than traditional treatments.

At Adler Footcare we use live birth stem cells which are introduced into the affected area. Stem cells are used by many physicians to treat a broad variety of conditions because of their ability to either replicate themselves, or change into the cell type that is needed to repair the tissue that has been damaged. When a patient comes in for stem cell therapy, the affected area is carefully measured so the stem cells can be delivered directly to the area that needs the treatment.

The Joint Commission accredited Podiatric OR of Midtown Manhattan housed within Adler Footcare is designed to facilitate advanced treatments such as Stem Cell Replacement Therapy to all their patients.

With stem cell treatment we are finding that patients heal much faster and are able to return to their normal activities much sooner than with traditional treatment options, said Dr. Darline Kulhan, podiatric surgeon at Adler Footcare. Recovery time depends on each individual patients medical diagnosis and overall general health.

Treatments using stem cells have been used by physicians for over 100 years. Stem Cell Replacement Therapy is covered by commercial insurance and Medicare, and is approved and regulated by the FDA. The product is tested and screened by medical professionals to eliminate the potential of any communicable diseases.

A team of international scientists, including a researcher from Simon Fraser University, has isolated a gene thought to play a causal role in the development of Alzheimer's disease. The Proceedings of the National Academy of Sciences recently published the team's study.

The newly identified gene affects accumulation of amyloid-beta, a protein believed to be one of the main causes of the damage that underpins this brain disease in humans.

The gene encodes a protein that is important for intracellular transportation. Each brain cell relies on an internal highway system that transports molecular signals needed for the development, communication, and survival of the cell.

This system's impairment can disrupt amyloid-beta processing, causing its eventual accumulation. This contributes to the development of amyloid plaques, which are a key hallmark of Alzheimer's disease.

Teasing out contributing disease factors, whether genetic or environmental, has long posed a challenge for Alzheimer's researchers.

"Alzheimer's is a multifactorial disease where a build-up of subtle problems develop in the nervous system over a span of decades," says Michael Silverman, an SFU biology associate professor. He worked on the study with a team of Japanese scientists led by Dr. Takashi Morihara at Osaka University.

Identifying these subtle, yet perhaps critical genetic contributions is challenging. "Alzheimer's, like many human disorders, has a genetic component, yet many environmental and lifestyle factors contribute to the disease as well," says Silverman. "In a sense, it is like looking for a needle in a complex genetic haystack."

Only a small fraction of cases have a strong hereditary component, for example early-onset Alzheimer's.

This breakthrough in Alzheimer's research could open new avenues for the design of therapeutics and pave the way for early detection by helping healthcare professionals identify those who are predisposed to the disease.

"One possibility is that a genetic test for a particular variant of this newly discovered gene, along with other variants of genes that contribute to Alzheimer's, will help to give a person their overall risk for the disease. Lifestyle changes, such as improved diet, exercise, and an increase in cognitive stimulation may then help to slow the progression of Alzheimer's," says Silverman.

Perhaps the biggest fear raised by advances in genetic engineering like the ability to create a baby with three parents is that we are heading straight down a road that leads to eugenics the attempt to create perfect "designer" babies.

From "Star Trek" to "Star Wars" to many more films like "Gattaca" and "The Boys from Brazil," Hollywood has warned us time and again that genetic engineering of animals or people is nothing but bad news.

History sadly also shows the horror that eugenics programs have produced in Germany, Japan and many other nations when some people are deemed more desirable and others are seen as defective, burdensome or subhuman. Death camps, forced sterilization, restrictions on marriage, exile, concentration camps, prohibitions on immigration all have all been carried out in the name of eugenics.

But Hollywood is wrong. Not everything about genetic engineering is morally horrible. Nor is human genetic engineering always motivated by eugenic goals.

"Hollywood is wrong. Not everything about genetic engineering is morally horrible."

The FDA is considering approving an experiment to repair a genetic disease in humans by creating embryos with DNA from three parents. Genes would be transferred from a healthy human egg to one that has a disease and the "repaired" egg then fertilized in the hope that a healthy baby will result. The goal of the experiment in genetic engineering is not a perfect baby but a healthy baby.

One in 4,000 children inherit terrible diseases due to genetic mutations in their mitochondria. The mitochondria are the batteries of cells. They provide the energy that lets cells divide and grow. All mitochondria are inherited from the mother from her eggs. And, the mitochondria are separate, tiny units in the egg meaning you can pick them out and transplant them.

So if you know that a mitochondrial disease runs in your family, you might want to try getting pregnant using one of your eggs that has been genetically engineered to have mitochondria from a donor egg.

None of this should raise concerns about abortion. Only eggs, not embryos, would be involved. There are, however, safety concerns. We won't really know if mitochondrial transplants work until healthy young people exist who have been made using the technique. Studies in primates look promising but safety in humans is still a risk.

"How far we go in engineering future generations through genetic manipulations is up to us."

New Rochelle, NY, February 26, 2014Whole body cooling in comatose patients who have suffered a heart attack can limit the damage to brain tissue caused by the restoration of blood flow and oxygen. But new data indicate that in certain patients therapeutic hypothermia is less effective and may even worsen neurological outcomes, as described in an article in Therapeutic Hypothermia and Temperature Management, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Therapeutic Hypothermia and Temperature Management website at http://www.liebertpub.com/ther.

Timothy Mader and coauthors representing the CARES Surveillance Group (Baystate Medical Center, Tufts University School of Medicine, Springfield, MA; OptiStatim, LLC, Longmeadow, MA; Emory University School of Medicine, Atlanta, GA) conclude that while therapeutic hypothermia may be effective for certain patient subsets, "more uniform and rigid guidelines for application are needed to assure more appropriate application."

The authors measured neurological outcomes at hospital discharge among a large group of adults who suffered heart attacks out of the hospital. They compared the results among patients whose hearts resumed beating with or without the need to be shocked and report their findings in the article "Comparative Effectiveness of Therapeutic Hypothermia After Out-of-Hospital Cardiac Arrest: Insight from a Large Data Registry."

"This manuscript is important to the field of therapeutic hypothermia in that it points to a need for additional research to be conducted and guidelines developed to clarify specific patient populations that will most benefit from cooling strategies," says W. Dalton Dietrich, III, PhD, Editor-in-Chief of the Journal and Kinetic Concepts Distinguished Chair in Neurosurgery, Professor of Neurological Surgery, Neurology and Cell Biology, University of Miami Leonard M. Miller School of Medicine.

An international team of researchers led by an endocrinologist at Ludwig-Maximilians-Universitaet (LMU) in Munich has identified genetic mutations that result in uncontrolled synthesis and secretion of the stress hormone cortisol.

Cortisol is a hormone that is produced by the adrenal gland in response to stressful events, and modulates a whole spectrum of physiological processes. An international research collaboration has now identified genetic mutations that lead to the production and secretion of cortisol in the absence of an underlying stressor.

The discovery emerged from the genetic characterization of benign tumors of the adrenal gland which produce cortisol in excess amounts. Patients who develop such tumors suffer from weight gain, muscle wasting, osteoporosis, diabetes and hypertension. This condition, known as Cushing's syndrome, can be successfully treated by surgical removal of the affected adrenal gland.

Overproduction of cortisol

The team, which included researchers from Germany, France and the US and was led by Professors Felix Beuschlein and Martin Fassnacht of the LMU Medical Center, were able to show that in one-third of a patient population with such adrenal tumors, a mutation in the gene for the enzyme phosphokinase A was specifically associated with the continuous production of cortisol. This mutation had occurred in the adrenal gland and is therefore restricted to the tumor cells. The results have just appeared in the prestigious New England Journal of Medicine.

"The gene for phosphokinase A plays a key role in the regulation of adrenal gland function, and the newly identified mutation causes it to become irreversibly activated, which results in the unrestrained production of cortisol," says Felix Beuschlein. In collaboration with a group at the US National Institutes of Health, the team was also able to identify patients who carry similar genetic alterations in their germline DNA. In these families, Cushing's syndrome occurs as a heritable genetic disease.

The elucidation of the genetic mechanism responsible for a significant fraction of cases of Cushing's syndrome provides a new diagnostic tool, and may also lead to new approaches to treatment. To enable further investigations towards this end, the German Cushing Register, which is maintained by Professor Martin Reincke at the LMU Medical Center, has received a grant of 400,000 euros from the Else Krner-Fresenius Foundation. A recently initiated European research consortium devoted to the study of Cushing's syndrome, of which Professors Beuschlein and Fassnacht are members is supported by a grant of 700,000 euros from the ERA-NET program administered by the Federal Ministry for Education and Research.

As the price for decoding a person's DNA keeps dropping, expectations for personalized medicine based on specific genetic profiling rise. But translating an individual's genetic data into finely tailored medical treatments still faces major challenges, explains a new article in Chemical & Engineering News (C&EN), the weekly magazine of the American Chemical Society.

Rick Mullin, senior editor at C&EN, notes that advances in DNA sequencing have allowed researchers to design some therapies, particularly in the cancer realm, for patients with certain genetic traits. As the technology for reading people's genes improves and drops even further in cost, more progress is on the horizon. The U.S. Food and Drug Administration, the government body responsible for approving pharmaceuticals for commercialization, supports these efforts. With the stars seemingly aligned, some industry experts have declared that the age of personalized medicine has arrived. So why do others claim that victory is still a long way off?

The article points out that when pharmaceutical labs launched their search for new drugs based on genomics more than 15 years ago, the focus was almost exclusively on DNA sequences. But now researchers have realized that for personalized medicine to truly take hold, they need to also pay attention to individuals' health histories, their environments and how their genes actually translate into physical traits. This requires a shift in thinking, plus closer ties between the research and clinical sides, and ultimately, insurers. But perhaps the tallest barrier is cultural an attitude among some in the health care industry to simply continue business as usual.
