Key findings for all veterans seen in depression and suicide study
10-30-2007 · EurekAlert!The largest and most up-to-date study of suicides among depressed veterans provides important new data -- and some surprises -- that may guide screening and treatment for all vets. Predictors of suicide among depressed veterans differ from those seen in the general population, with younger, white, non-Hispanic veterans having the highest risk. Surprisingly, older veterans who had been diagnosed with post-traumatic stress disorder and depression had a lower overall rate of suicide than those without PTSD.

- How parents react to material hardship found to be key to how income affects children
02-07-2007 · EurekAlert!
Research drawing from the "Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999" challenges the accepted finding that family income is directly associated with parental stress. The study found that parents who make more money can better provide more cognitively stimulating materials, and that material hardship can lead to parental depression and conflict. These effects in turn may cause parents to show less affection towards children, who then may become depressed or misbehave.

- How insulin-producing cells develop -- new finding could help fight against diabetes
05-17-2007 · EurekAlert!
A key aspect of how embryos create the cells which secrete insulin is revealed in a new study published tomorrow in the Journal of Biological Chemistry. The researchers hope that their findings will enable the development of new therapies for diabetes, a condition caused by insufficient levels of insulin. The research reveals that glucose plays a key role in enabling healthy beta cells, which secrete insulin, to develop in the pancreas of an embryo.

- Key to success in IS -- Quality and usefulness, not user satisfaction, says Management Insights
01-05-2007 · EurekAlert!
A study focusing on information systems says that quality and usefulness trump user satisfaction in the quest for success. The findings are the subject of a paper in the Management Insights section of the current issue of Management Science, the flagship journal of the Institute for Operations Research and the Management Sciences (INFORMS®).

- Study identifies new regulator of fat metabolism
06-05-2007 · EurekAlert!
Over the past several years, animal studies have shown that high-fat, low-carbohydrate "ketogenic" diets cause demonstrable changes in metabolism and subsequent weight loss. Now, researchers at Beth Israel Deaconess Medical Center (BIDMC) have identified a key mechanism behind this turn of events. Their findings, which appear in the June 2007 issue of Cell Metabolism, demonstrate that a liver hormone known as FGF21 is required to oxidize fatty acids -- and thereby burn calories.

- Rain forest protection works in Peru
08-09-2007 · EurekAlert!
A new regional study shows that land-use policies in Peru have been key to tempering rain forest degradation and destruction in that country. Scientists at the Carnegie Institution's Department of Global Ecology led an international effort to analyze seven years of high-resolution satellite data covering most (79 percent) of the Peruvian Amazon for their findings.

- Researchers at BMC find disability does not necessarily follow disease in living to old age
02-11-2008 · EurekAlert!
Researchers from Boston Medical Center's New England Centenarian Study report that for a substantial proportion of their centenarian subjects, avoiding age-related diseases (i.e., stroke, cardiovascular disease, diabetes) may not be the key to their longevity; rather, the avoidance of disability may be a key feature in their exceptional survival. These findings appear in the February 11 issue of Archives of Internal Medicine.

- A novel finding in how chikungunya virus has spread to new vectors and locations
12-06-2007 · EurekAlert!
Researchers at the University of Texas Medical Branch have discovered how a key protein switch allows chikungunya virus to spread to new vectors. The study, published Dec. 7 in PLoS Pathogens, explains how the virus has increased its ability to infect and be transmitted by the Asian tiger mosquito, Aedes albopictus.

- Brain images show hysteria not an imaginary disorder
12-11-2006 · EurekAlert!
In what's being called a novel finding, researchers using brain scans have uncovered evidence of cerebral dysfunction in women with sensory conversion disorder, better known as hysteria. The study's findings open up a new window to understanding hysteria, an unexplained neurological disorder in which a patient complains of symptoms, but doctors can't find anything medically wrong with them. The study is published in the December 12, 2006, issue of the journal Neurology.

- Study revises dynamin's role in nerve cell function
05-11-2007 · EurekAlert!
An unexpected finding on how nerve cells signal to one another could rewrite the textbooks on neuroscience, says a collaborative team of researchers at Weill Cornell Medical College and Yale University. Their study, published as a high-profile research article in the journal Science, suggests that a key cellular enzyme called dynamin 1 is not essential to all synaptic transmission, as experts had previously assumed.
