Amino acid arginine could help fight human obesity

A Texas AgriLife Research scientist and fellow researchers have discovered that arginine, an amino acid, reduces fat mass in diet-induced obese rats and could help fight human obesity.

Disruption of circadian clock can suppress cancer growth

Researchers at the University of North Carolina at Chapel Hill have shown that disruption of the circadian clock - the internal time-keeping mechanism that keeps the body running on a 24-hour cycle - can slow the progression of cancer.

Exposure to second-hand smoke and alcohol significantly raises the risk of liver disease

The finding adds to mounting evidence that tobacco smoke and alcohol are worse for health as a combination, beyond the individual exposure risks, said Shannon Bailey, Ph.D., an associate professor in the UAB Department of Environmental Health Sciences and a co-lead author on the study.

Link found between genetic and environmental causes of Parkinson's disease

Scientists at the Whitehead Institute for Biomedical Research have found that a single gene, known as PARK9, protects cells from manganese toxicity and rescues neurons from over-expression of the protein alpha-synuclein.

New test predicts how breast cancer patients respond to chemotherapy

Researchers at the Swiss Institute of Bioinformatics and the Swiss National Center of Competence in Research in Molecular Oncology in Lausanne have developed a new test to predict how breast cancer patients respond to chemotherapy, which could help change how treatment is delivered in the future.

Discovery of new cause of ozone wheezing and potential treatments

Researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, and Duke University have discovered a cause of airway irritation and wheezing after exposure to ozone, a common urban air pollutant.

New technology rapidly detects tumor response to chemotherapy

New technology developed by Duke University bioengineers can help clinicians more precisely detect whether specific cancer drugs are working, and should give basic researchers a powerful new tool to better understand the underlying mechanisms of cancer development.

Heavy dope smoking can damage developing brain in teens, young adults

Adolescents and young adults who are heavy users of marijuana are more likely than non-users to have disrupted brain development, according to a new study.

Genetic change prevents cell death in mouse model of Parkinson's disease

By shifting a normal protective mechanism into overdrive, a University of Wisconsin-Madison scientist has completely shielded mice from a toxic chemical that would otherwise cause Parkinson's disease.

New potential targets for colitis-associated cancer

Recent research from the laboratory of Michael Karin, PhD, at the University of California, San Diego School of Medicine - the first researcher to demonstrate a molecular link between inflammation and cancer - has identified two potential targets for the prevention and treatment of colitis-associated cancer (CAC), the most serious complication of inflammatory bowel disease.

The end of sex as we once knew it

Women are not from Venus any more than men are from Mars. But even though both sexes are perfectly terrestrial beings, they are not lacking in other differences. And not only in their reproductive organs and behavior, either, but in such unsexy characteristics as the propensity for drug abuse, fine motor control, reaction to stress, moods and many brain structures.

BioGenes as new designated partner in EU funded dementia project

BioGenes GmbH, a specialist in sophisticated antibody development, has been chosen as a new partner of cNEUPRO. cNEUPRO is a EU funded research project to analyse neurodegenerative diseases and discover novel biomarkers, and so improve early and differential diagnosis of Alzheimer's dementia.
