Relationship between drinking early in adolescence and later negative outcomes

Alcohol experimentation in late childhood or early adolescence is a common event. An early age of first drink (AFD), however, is associated with a variety of negative outcomes.

SLITRK1 gene appears to contribute to some cases of Tourette's Syndrome

In what may be a major milestone in Tourette's Syndrome (TS) research, scientists at Yale School of Medicine and their colleagues have identified a gene called SLITRK1 that appears to contribute to some cases of TS, according to a report in the October 14 issue of Science.

Chromosomes in the nucleus of the cell carry the material of heredity, or genes

Abnormal cell division that yields cells with an extra set of chromosomes can initiate the development of tumors in mice, researchers at Dana-Farber Cancer Institute have shown, validating a controversial theory about cancer causation put forth by a scientific visionary nearly 100 years ago.

Personalized medicine to improve the outcome for breast cancer patients

As cancer remains a leading cause of death in the United States, early detection and treatment are critical keys to improving the survival rate. Yet, an individual's response to treatment varies considerably, even among cancers of the same histological type.

Biologists uncover pivotal role of a gene called "Cut"

A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health consequences.

New fungal defensin, plectasin, possesses as much power as penicillin

A peptide identified in a fungus found in northern European pine forests possesses as much power as penicillin as well as vancomycin, according to an international team of researchers.

Novel therapies for pleural mesothelioma

Researchers at New York University School of Medicine and Wayne State University have found a molecule that reveals the early stages of pleural mesothelioma, a chest cancer caused by asbestos. The finding opens the way to a blood test for the disease, according to a new study published in the Oct. 13 issue of The New England Journal of Medicine.

New study of the public's priorities for the funding of research into what people eat and how it affects their health

The study, conducted by MORI Social Research Institute, explores any differences between the agendas of the public and research funders at a time when the health implications of the food that we consume have a very high profile. The study was commissioned by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Institute of Food Research (IFR), who will consider the results as part of their strategic planning for future funding.

One in nine women in the UK now risk contracting breast cancer during their lifetime

Some scientists argue that the cause may be an increased exposure to a number of environmental chemicals, a claim taken up by campaigners in the US and the UK who urge the government to provide better health protection.

New hormone discovery has implications for liver diseases

Researchers at UT Southwestern Medical Center have discovered that the small intestine communicates with the liver to control the production of bile acids - a finding that has great medical implications in treating people at risk for certain types of liver disease.

Obesity associated with a threefold increase in SCD1 expression in obese muscle

The gene encoding an enzyme that hinders muscle from burning fat manufactures three times more enzyme in the muscle of obese people than lean people, researchers from Duke University Medical Center and Louisiana State University have found. This causes the obese muscle tissue to both store more fat and burn less fat, the researchers said.

Sleletal muscle findings highlight the importance of exercise in obese people

The findings suggest that muscle bears a metabolic memory of obesity, which may help to explain why sustained weight loss can be difficult despite cutting calories, according to the researchers. Exercise might more successfully override the aberrant metabolic program in muscle, they suggest, thereby improving the long-term prognosis of those prone to obesity.

Experimental HIV vaccine progresses in trials

A novel vaccine targeted to multiple HIV subtypes found worldwide has moved into the second phase of clinical testing, the National Institute of Allergy and Infectious Diseases (NIAID) announced today.

Aging may intensify and prolong feeling run down when common infections like the flu occur

A new study, done with mice and published in the Federation of the American Societies of Experimental Biology Journal, suggests that miscommunication between the immune system and brain may be to blame for extended sickness symptoms and other cognitive disorders in elderly people and animals with an infection.

Myriad Genetics nears completion of antithrombin drug trial

Myriad Genetics announced today that it is rapidly nearing completion of the preclinical data package on MPC-0920, its antithrombin drug candidate, for submission to the FDA prior to beginning human clinical trials.

New treatments for health conditions related to abnormal iron metabolism

A new study conducted by scientists at Children's Hospital Oakland Research Institute could help researchers develop new treatments for a variety of health conditions that are all related to abnormal iron metabolism. More than one million Americans have abnormal iron levels in their bodies.

Technique for inserting genes into specific sites on the genome in liver cells

The genes are inserted into non-coding regions of the genome so there is no danger of interfering with the functioning of other genes. Once inserted, the gene remains a permanent part of the cell's genome.

The rise of breast cancer

In a continuing increase in breast cancer, one in nine women in the UK now risk contracting the disease during their lifetime.

Important milestone towards more individually targeted and effective treatments for cancer patients

The research team has now identified crucial genes in a range of common cancers that have been reported to predict a patient's response to treatment. This follows the team's earlier success in studying a tumor suppressor gene associated with acute lymphoblastic leukaemia (ALL) in children.

Prozac helps learning and memory in people with Huntington's disease

People with Huntington's disease have progressive motor problems, cognitive deficits (dementia) and psychiatric symptoms (the most common is depression) that usually start to appear in mid-life. There is no cure and death usually results within 10 to 20 years of symptom onset, or faster in the childhood-onset form of the disease.
