Green tea polyphenols thwart prostate cancer development at multiple levels
The polyphenols present in green tea help prevent the spread of prostate cancer by targeting molecular pathways that shut down the proliferation and spread of tumor cells, as well as inhibiting the growth of tumor nurturing blood vessels, according to research published in the 1 December issue of Cancer Research.  more

Simple intervention nearly eliminates catheter-related bloodstream infections
As many as 28,000 patients die each year in the U.S. because of catheter-related bloodstream infections, but doctors and nurses who implement simple and inexpensive interventions can cut the number of deaths to nearly zero, according to a study by Johns Hopkins researchers.  more

Small study shows SAMe may improve treatment of depression
Massachusetts General Hospital (MGH) researchers have found that adding the nutritional supplement SAMe to a standard antidepressant may be helpful to patients who have not responded to single-drug treatment for clinical depression. The pilot study, appearing in the December Journal of Clinical Psychopharmacology, found that treatment with both SAMe and an antidepressant improved symptoms in half the study participants and produced complete relief of symptoms in 43 percent of participants. more


Imatinib (Gleevec) has activity in AIDS-related Kaposi's sarcoma
A new clinical study has shown that imatinib mesylate (Gleevec) has activity in AIDS-related Kaposi's sarcoma (KS).
