Study finds blocking angiogenesis signaling from inside cell may lead to serious health problems
08-23-2007 · EurekAlert!Angiogenesis inhibitors that block a tumor's development of an independent blood supply have been touted as effective cancer fighters that result in fewer side effects than traditional chemotherapy. However, a new study by researchers at UCLA's Jonsson Cancer Center showed that one method of blocking blood supply development could result in serious and potentially deadly side effects.

- Killing the messenger RNA -- But which one?
02-22-2007 · EurekAlert!
Tiny molecules called microRNAs are able to effectively silence large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA. Now, a new study shows that microRNAs can undergo a kind of molecular editing, and a single substitution in their sequence can redirect them to silence entirely different sets of genes from their unedited counterparts. Further, errors in the editing can lead to serious health problems.

- Geisinger study: PTSD a medical warning sign for long-term health problems
02-13-2008 · EurekAlert!
New Geisinger research finds that post-traumatic stress disorder is an indicator of long-term health problems, similar to biological warning signs such as elevated white blood cell counts. With an in-depth study of Vietnam vets, pioneering PTSD researcher Joseph Boscarino shows that PTSD leaves a distinct biological mark on a person's overall health. Considered a psychological or mental health problem, PTSD should now be viewed as a threat to a person's physical health, Boscarino concludes.

- Abnormal proteins linked to schizophrenia found in body tissue
12-20-2006 · EurekAlert!
A new study suggests biochemical changes associated with schizophrenia aren't limited to the central nervous system and that the disease could have more encompassing effects throughout the body than previously thought. The findings, scheduled for publication in the January 2007 issue of the American Chemical Society's Journal of Proteome Research, could lead to better diagnostic testing for the disease and help explain why those afflicted with it are more prone to other chronic health problems.

- Nicotine may accelerate atherosclerosis, may be as dangerous as tar
09-12-2007 · EurekAlert!
It's well known that smoking cigarettes increases risk for a host of serious health problems from cancer to heart disease. Now a new study from Weill Cornell Medical College in New York City looks at how they do their dirty work by contributing to atherosclerosis, or hardening of the arteries. The evidence points to nicotine, the addictive chemical in cigarettes.

- Geisinger launches extensive study on obesity and related liver problem
04-16-2007 · EurekAlert!
Geisinger Health System researchers in Danville, Pa., are looking at the genetics of obesity through a unique study. Geisinger patients have voluntarily donated more than 600 liver tissue samples so that researchers can study obesity and also develop a safer, noninvasive way of detecting an obesity-related condition: nonalcoholic fatty liver disease. Relying on several core system resources in the study, Geisinger researchers hope to know more about nonalcoholic fatty liver disease and related health problems.

- AASM encourages those student-athletes at risk for developing osa to visit a sleep clinic
08-24-2007 · EurekAlert!
More research is emerging that sheds light on a serious problem affecting student-athletes nationwide: the number of children and teens who are considered obese is rising dramatically. According to the American Academy of Sleep Medicine, obesity raises the risk of cardiovascular disease and other health problems, and also increases the likelihood of developing obstructive sleep apnea.

- Antioxidant overload may underlie a heritable human disease
08-09-2007 · EurekAlert!
Despite the popular notion that antioxidants, such as vitamins C and E, offer health-promoting benefits by protecting against damaging free radicals, a new study in the Aug. 10 issue of the journal Cell reveals that, in fact, balance is the key. The researchers show in mice that an overload of natural antioxidants can actually lead the heart to failure.

- OHSU lab finds meth receptor that could lead to therapy
04-18-2007 · EurekAlert!
A recently discovered signaling system in the brain has just been shown to be turned on by methamphetamine, an Oregon Health & Science University study found. The signaling system could soon become a target for therapies aiming to reverse meth's adverse health effects as well as reduce the craving that drives its abuse. "… We provide clear evidence that methamphetamine is a full and potent agonist of TAAR1," says OHSU researcher Dr. David Grandy.

- Study shows lead-based paint problem isn't isolated to China
09-27-2007 · EurekAlert!
A multinational team of environmental and occupational health researchers has found that consumer paints sold in Nigeria contain dangerously high levels of lead. Increased globalization and outsourcing of manufacturing has drastically increased the likelihood that products with unacceptably high levels of lead are being traded across borders -- including between China and Africa as well into regulated countries like the US.
