Scientists find war vets' hand dexterity determines susceptibility to PTSD

05-22-2007 · EurekAlert!

With the wars in Iraq and Afghanistan continuing, an investigator with the Geisinger Center for Health Research in Danville, Pa., has found a clear link between post-traumatic stress disorder and veterans' handedness. In fact, veterans who use both of the hands more often are more likely to experience PTSD according to Dr. Joseph Boscarino's study, which is being published in the May issue of Psychosomatic Medicine. The study examined PTSD among 2,490 Vietnam veterans.

New gene test for prostate cancer at hand
01-17-2008 · EurekAlert!
Men with susceptibility for prostate cancer will soon be identifiable through a simple DNA test. So hope scientists at the Swedish medical university Karolinska Institutet, who have shown that men carrying a combination of known risk genes run a four to five times higher risk of developing prostate cancer. At present, men with suspected prostate cancer are identified mainly using what are known as PSA tests. However, the test has a relatively low sensitivity and better methods are needed.

Mouse genome will help identify causes of environmental disease
07-29-2007 · EurekAlert!
Research on the DNA of 15 mouse strains commonly used in biomedical studies is expected to help scientists determine the genes related to susceptibility to environmental disease. The body of data is now publicly available in a catalog of genetic variants, which displays the data as a mouse haplotype map, a tool that separates chromosomes in to many small segments, helping researchers find genes and genetic variations in mice that may affect health and disease.

Columbia scientists determine 3-dimensional structure of cell's 'fuel gauge'
02-08-2007 · EurekAlert!
Researchers at Columbia University Medical Center have uncovered the complex structure of a protein that serves as a central energy gauge for cells, providing crucial details about the molecule necessary for developing useful new therapies for diabetes and possibly obesity. A paper published online today in the journal Science details this structure, helping to explain one of the cell's most basic and critical processes.

Scripps research scientists show protein accelerates breast cancer progression in animal models
06-20-2007 · EurekAlert!
Scientists at the Scripps Research Institute have shown for the first time that a cytokine called pleiotrophin stimulates the progression of breast cancer in both animal and cell culture models. The study, which tested three separate models to determine the role of inappropriate expression of pleiotrophin, found that it produced striking increases in aggressiveness of the breast cancer cells themselves.

Scientists develop a fast system to detect metal concentrations in iron and steel industry workers
11-20-2007 · EurekAlert!
This method will analyze the levels of chromium, manganese and nickel in the employee's organism to determine possible work-related poisoning. Scientists from the University of Granada proposed to replace traditional blood and urine analyses with saliva and hair analyses, which are less invasive. A course at the Centro Mediterraneo at UGR on waste treatment discussed health problems caused by continuous exposure to different poisons.

Feds fund study of drug that may prevent radiation injury
01-28-2008 · EurekAlert!
The Department of Defense has commissioned a nine-month study from Rice University chemists and scientists in the Texas Medical Center to determine whether a new drug based on carbon nanotubes can help prevent people from dying of acute radiation injury following radiation exposure. The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently available.
