- Study suggests some brain injuries reduce the likelihood of post-traumatic stress disorder
12-23-2007 · EurekAlert!
A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder. The findings, from the National Institutes of Health and the National Naval Medical Center, suggest that drugs or pacemaker-like devices aimed at dampening activity in these brain regions might be effective treatments for PTSD.

- Study examines decision-making deficits in older adults
01-14-2008 · EurekAlert!
Recent work led by University of Iowa neuroscientist Natalie Denburg, PhD, suggests that for a significant number of older adults, measurable neuropsychological deficits do seem to lead to poor decision-making and an increased vulnerability to fraud. The findings also suggest that these individuals may experience disproportionate aging of a brain region critical for decision-making.

- Government dietary guidelines, unintended consequences and public policy
01-30-2008 · EurekAlert!
In the years following the government promotion of a low-fat diet, obesity in America has reached almost epidemic levels. What role did the federal guidelines play? In a study published in the March 2008 issue of the American Journal of Preventive Medicine, Paul R Marantz, Elizabeth Bird, Michael H. Alderman, of Albert Einstein College of Medicine, suggest that the government issued these recommendations based on limited scientific data and assumed that no harm would result, but the evidence now suggests otherwise.

- Study suggests estrogen deficiency can lead to obesity-induced high blood pressure after menopause
08-08-2007 · EurekAlert!
At menopause, women lose hormone protection against heart and kidney diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity. The results of their study, using an animal model, suggest that estrogen depletion can have these effects.

- Treatment with SN reduces injury to the brain following stroke
12-13-2007 · EurekAlert!
Stroke is the term used to describe deteriorating brain function due to either the leaking of blood vessels (hemorrhage) or oxygen deprivation (ischemia) in the brain. A new report has revealed a beneficial effect of the protein secretoneurin in rat with ischemia-induced stroke, leading the authors of the study to suggest that SN holds promise as a small-molecule drug for the treatment of individuals who have had a stroke.

- Feeling hot, hot, hot: New study suggests ways to control fever-induced seizures
08-21-2007 · EurekAlert!
Scientists at the University of Toronto Mississauga and Queen's University show that genetic variation in the foraging gene results in different tolerance for heat stress and demonstrate how the use of specific drugs can replicate this effect in fruit flies and locusts. While the findings are at an early stage, the researchers suggest that they could lead to ways to rapidly protect the brain from extremely high fevers in mammals, including humans.

- Enzyme promotes fat formation
10-11-2007 · EurekAlert!
The enzyme TPPII may contribute to obesity by stimulating the formation of fat cells, suggests a study in EMBO reports this week. The enzyme, TPPII, has previously been linked to making people feel hungry, but Jonathan Graff and colleagues now show that it may be even more deeply involved in causing obesity.

- HIV exploits competition among T-cells
10-16-2006 · EurekAlert!
New HIV research shows how competition among the human immune system's T cells allows the virus to escape destruction and eventually develop into full-blown AIDS. The study, slated to appear in Physical Review Letters, employs a computer model of simultaneous virus and immune system evolution. It also suggests a new strategy for vaccinating against the virus -- a strategy that the computer simulations suggest may prevent the final onset of AIDS.

- The origin of the brain lies in a worm
04-20-2007 · EurekAlert!
Researchers from the European Molecular Biology Laboratory in Heidelberg now reveal that the vertebrate nervous system is probably much older than expected. The study, which is published in the current issue of Cell, suggests that the last common ancestor of vertebrates, insects and worms already had a centralised nervous system resembling that of vertebrates today.
