Novel set of genes linked with epithelial ovarian cancer patient survival

Researchers at Moffitt Cancer Center and colleagues from 11 other institutions in the United States and the United Kingdom have used two genome-wide association studies (GWAS) - one from the U.S. and one from the U.K. - to detect a novel set of genes found to be associated with epithelial ovarian cancer patient survival.

New research provides explanation for some of autism's mysteries

New research from Carnegie Mellon University's Marcel Just provides an explanation for some of autism's mysteries - from social and communication disorders to restricted interests - and gives scientists clear targets for developing intervention and treatment therapies.

Nitrogen balance occurs with a precise 24-hour rhythm in mammals

Researchers at Case Western Reserve University School of Medicine demonstrated that nitrogen balance, the process of utilizing amino acids and disposing of their toxic byproducts, occurs with a precise 24-hour rhythm - also known as circadian rhythm - in mammals. Disruption of this cycle has a direct impact on survival of organisms, and may predispose one to life altering diseases including diabetes and cardiovascular disease.

Yoga may be effective in treating patients with stress-related psychological and medical conditions

An article by researchers from Boston University School of Medicine (BUSM), New York Medical College (NYMC), and the Columbia College of Physicians and Surgeons (CCPS) reviews evidence that yoga may be effective in treating patients with stress-related psychological and medical conditions such as depression, anxiety, high blood pressure and cardiac disease.

Pten gene can also fight against obesity, ageing process

This result, obtained after five years' research, is published in leading journal Cell Metabolism. The authors, led by Manuel Serrano (CNIO), believe it will open the door to new therapeutic options not only against cancer, but against obesity and even the ageing process.

Scientists develop nanocombinatorics for directing stem cell differentiation

Northwestern University scientists have developed a powerful analytical method that they have used to direct stem cell differentiation. Out of millions of possibilities, they rapidly identified the chemical and physical structures that can cue stem cells to become osteocytes, cells found in mature bone.

Researchers reveal how melanoma develops resistance to Zelboraf

Cancer is tough to kill and has many ways of evading the drugs used by oncologists to try and eliminate it. Now, researchers at UCLA's Jonsson Comprehensive Cancer Center have uncovered how an advanced form of melanoma gets around an inhibitor, Zelboraf, which targets the mutated BRAF gene.

African Americans more likely to develop keloid after head and neck surgery

African Americans are seven times more likely than Caucasians to develop an excessive growth of thick, irregularly shaped and raised scarring on their skin - known as a keloid - following head and neck surgery, according to a new study from Henry Ford Hospital in Detroit.

CU Cancer Center aims to make progress against squamous cell lung cancer

Recent advances in targeted cancer treatments greatly bolster the prognosis for many types of lung cancer, but according to a University of Colorado Cancer Center investigator, "practically nothing has improved in squamous cell lung cancer in the last decades."

New imaging tool reveals subtle changes in breast tissue

Purdue University researchers have created a new imaging technology that reveals subtle changes in breast tissue, representing a potential tool to determine a woman's risk of developing breast cancer and to study ways of preventing the disease.

Scripps scientists to develop new generation of broad spectrum anti-cancer therapeutics

A pair of Scripps Research Institute scientists, one a cancer biologist and the other a chemist, has been awarded $3.85 million from the National Institutes of Health (NIH) to develop a new generation of broad spectrum anti-cancer therapeutics, including breast cancer and lymphoma.

Blocking Plexin B1 protein can prevent formation of breast cancer metastases

In particularly aggressive forms of breast cancer, cancer cells can settle in other organs and form metastases there. Once such metastases form, complete recovery is rare. Consequently, it is enormously important to prevent the metastasisation of the breast cancer cells. The success, however, achieved by using existing forms of therapy is limited.

Study evaluates link between genetic and environmental factors and risk of drug abuse

In a national Swedish adoption study, the risk for drug abuse appears to be increased among adopted children whose biological parents had a history of drug abuse, according to a report published Online First by Archives of General Psychiatry, one of the JAMA/Archives journals.

New AD marker can predict mental decline

A new marker of Alzheimer's disease can predict how rapidly a patient's memory and other mental abilities will decline after the disorder is diagnosed, researchers at Washington University School of Medicine in St. Louis have found.

Cenderitide may preserve cardiac function after heart attack

The National Heart, Lung and Blood Institute (NHLBI), a division of the National Institutes of Health (NIH), has awarded a $2.5 million grant to Mayo Clinic's Cardiorenal Research Laboratory to conduct a highly innovative research project, "Cardiovascular Peptides and Myocardial Infarction."

Study shows how new information is encoded into prefrontal cortex

The brain has a remarkable ability to learn new cognitive tasks while maintaining previously acquired knowledge about various functions necessary for everyday life. But exactly how new information is incorporated into brain systems that control cognitive functions has remained a mystery.

Penn-led team develops universal approach to personalized cancer therapy based on T cells

Researchers from the Perelman School of Medicine at the University of Pennsylvania report this month in Cancer Research a universal approach to personalized cancer therapy based on T cells. It is the first time a system for making an adaptable, engineered T-cell to attack specific tumor types has been proposed, depending on which abnormal proteins, called antigens, are expressed by individual patients' tumor cells.

Microneedle vaccine patches may effectively protect against flu

Recent research found that microneedle vaccine patches are more effective at delivering protection against influenza virus in mice than subcutaneous or intramuscular inoculation. A new, detailed analysis of the early immune responses by the Emory and Georgia Tech research team helps explain why the skin is such fertile ground for vaccination with these tiny, virtually painless microneedles.

Left hemisphere of the brain plays a critical role in creative thinking

It takes two to tango. Two hemispheres of your brain, that is. USC researchers are working to pin down the exact source of creativity in the brain - and have found that the left hemisphere of your brain, thought to be the logic and math portion, actually plays a critical role in creative thinking.
