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.

Fijiian seaweed shows potential to kill cancer cells, bacteria and the HIV virus

Researchers have discovered 10 new molecular structures with pharmaceutical potential in a species of red seaweed that lives in the shallow coral reef along the coastline of Fiji in the south Pacific Ocean.

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.

Psychological stress during infancy has been found to cause early impaired memory

The study suggests that the emotional stress associated with parental loss, abuse or neglect may contribute to the type of memory loss during middle-age years that is normally seen in the elderly.

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.

Third Wave Technologies files patent suits against Chiron and Bayer

The company last Friday filed suit against Digene Corp., seeking a court ruling supporting Third Wave's right to sell its human papilloma virus (HPV) products. Third Wave today also filed suit against Chiron Corp., Bayer Corp., and Bayer HealthCare LLC asking for a similar ruling about its right to sell its hepatitis C virus products.

Nanogen subsidiary, Epoch Biosciences issued new patent

Nanogen announced today its subsidiary, Epoch Biosciences, was issued Patent No. 6,951,930, "Hybridization-Triggered Fluorescent Detection of Nucleic Acids" by the U.S. Patent and Trademark Office.

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.

Astrocytes modulate adenosine - thought to be important in controlling wake-to-sleep transitions and epileptic seizures

Researchers at the University of Pennsylvania School of Medicine have demonstrated that star-shaped glial cells in the brain called astrocytes are directly involved in regulating communication between neurons.

People with epilepsy 4 times more likely to have attempted suicide before ever having a seizure

A new study concludes that widespread screening for cardiovascular risk by measuring blood levels of C-reactive protein (CRP), a protein produced by the liver, should not be advocated.

Depression both increases the risk for developing epilepsy and is also common among people with epilepsy who experience many seizures

Researchers have found provocative evidence that the brain dysfunction that underlies epilepsy may also determine whether people are at risk for suicide. The study, published online October 10, 2005 in the Annals of Neurology, also suggests that depression and suicide may have different brain mechanisms.

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.
