Putting feelings into words produces therapeutic effects in the brain

...ssing in the left side of the brain; however, this effect was occurring only in this one region, on the right side of the brain,” he said. “It’s rare to see only one region of the brain responsive to a high-level process like labeling emotions.” Many people are not likely to realize why putting their fee...

First confirmed common genetic risk factors for breast cancer

... a large number of genetic loci, each with a small effect on breast cancer risk. "Breast cancer likely involves many risk genes, and each gene only confers a moderate risk for disease," Dr. Liu explained. While the findings of the international research collaboration hopefully will fuel the developmen...

Pistachios lower cholesterol, provide antioxidants

...se it would appear that pistachios are causing the effect and that they act in a dose dependent way," says Gebauer. In addition, during this study researchers, researchers looked at the effects of these diets on oxidized LDL and on antioxidants in the blood. "We were trying to see if the increased l...

First clinical trial of gene therapy for childhood blindness

...ill need to be followed-up to assess the long term effect of the treatment. It will be many months before we have the full picture. We anticipate the best outcome in younger patients, as we will be treating the disease in the early stages of its development." Professor Ali added: "There are many forms o...

8 plants from South Africa may hold potential for treating high blood pressure

...e o-phthaldialdehyde was measured to determine the effect of the plant on ACE activity. Plasma ACE activity was determined using rat plasma. The IC50 of the conventional ACEI, captopril was determined to test the sensitivity of the assay. At least three separate determinations were conducted for each tes...

Targeting sugar on blood vessels may inhibit cancer growth

...the tumor ‘fuels?for angiogenesis, without a major effect on normal vascular function." The researchers hope to develop novel therapies by inhibiting endothelial heparan sulfate in the tumor environment. An example would be developing small-molecule inhibitors of Ndst1. By affecting a broad array of mo...

"Combination therapy results for reovirus in animals are particularly encouraging because they suggest that Reolysin can improve the anti-tumor activity of standard chemotherapy agents in advanced cancer patients w...

High-dose anticlotting drug cuts heart attack, death risk in half

...en the clogged coronary artery. To evaluate the effect of the clopidogrel loading dose, researchers from University of Turin and Virginia Commonwealth University, in Richmond, performed a meta-analysis of data from 10 studies involving more than 1,500 patients. Roughly half of the patients were pretreate...

DNA-damage test could aid drug development

...n on animal testing of cosmetic products goes into effect in 2009." Next steps in the research, which may be carried out by industry partners, will be to test the assay in rats and other organisms, and with a wide variety of other toxic chemicals. "This research is the first stage in a new type of cli...

Gene thought to assist chemo may help cancer thrive

... survived and who didn't. What did seem to have an effect was whether p53 was working or not in the chemotherapy-treated tumors. A standard belief in cancer research is that a working p53 is essential in helping chemo patients because it turns on the killing mechanism for the cells that were damaged by c...
