Some brain-damaged patients quit smoking with ease, researchers report in Science
01-25-2007 · EurekAlert!A silver dollar-sized region deep in the brain called the insula is intimately involved in smoking addiction, and damage to this structure can completely erase the body's urge to smoke, researchers have discovered. The findings appear in the January 26, 2007 issue of the journal Science, published by AAAS, the nonprofit science society.

- OHSU findings may improve how people with chronic heartburn, precancer of the esophagus are screened
12-04-2006 · EurekAlert!
Researchers in the Oregon Health & Science University Digestive Health Center are first to report that screening people with chronic heartburn or pre-cancer of the esophagus in an office setting using a "skinny scope" is as accurate, less expensive and less risky than a traditional sedated screening in a procedure room -- and patients prefer it. The findings are published online and in print in this month's issue of the American Journal of Gastroenterology.

- Drugs for Parkinson's disease may ease stroke-related disability
04-10-2007 · EurekAlert!
Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease. Researchers at Washington University School of Medicine in St. Louis showed that stroke damage in a brain region known as the putamen is strongly linked to motor neglect, a condition that makes patients slow to move toward the left side.

- Diabetes drug shows promise for preventing brain injury from radiation therapy
01-10-2007 · EurekAlert!
Researchers at Wake Forest University School of Medicine are the first to report that in animal studies, a common diabetes drug prevents the memory and learning problems that cancer patients often experience after whole-brain radiation treatments.

- Rare case of dental patient-to-patient hepatitis B virus transmission recorded
04-03-2007 · EurekAlert!
Researchers have documented a case of hepatitis B virus (HBV) transmission between two patients at a dentist's office in the United States. While this kind of infection is exceedingly rare, universal vaccination against the virus would likely have prevented both cases, according to the authors of the case report and an accompanying commentary. Both appear in the May 1 issue of the Journal of Infectious Diseases, now available online.

- Researchers use new method to probe recollections in memory-impaired patients
02-04-2008 · EurekAlert!
Neuroscientists continue to debate whether or not long-term memory always depends on a region of the brain called the medial temporal lobe, which contains the brain's memory-processing center, the hippocampus. A new study of brain-damaged patients by researchers at the University of California-San Diego School of Medicine readdresses the issue using a new method to elicit more detailed long-term memories.

- Blocking immune cell action increases Alzheimer's-associated protein deposits
03-27-2007 · EurekAlert!
The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder. A report from Massachusetts General Hospital researchers finds that lack of a protein required for recruitment of the brain's primary immune cell led to increased amyloid-beta deposits and earlier death in a mouse model of Alzheimer's disease.

- Study: Donated embryos could result in more than 2,000 new embryonic stem cell lines
06-20-2007 · EurekAlert!
In a survey of more than 1,000 infertility patients with frozen embryos, 60 percent of patients report that they are likely to donate their embryos to stem cell research, a level of donation that could result in roughly 2,000 to 3,000 new embryonic stem cell lines. Researchers from Duke University and Johns Hopkins University report the startling findings in the July 6, 2007, issue of Science.

Chilean researchers have identified a region of the brain -- the insular cortex -- that plays a role in drug craving in amphetamine-addicted rats, according to a report published in the Oct. 26 issue of the journal Science, published by the American Association for the Advancement of Science, the nonprofit science society.
