On the heels of the fourth International AIDS Society?s Conference on HIV Pathogenesis, Treatment and Prevention, which took place in Sydney in late July, AIDS Healthcare Foundation (AHF) welcomed yesterday?s news that the FDA has approved Pfizer Inc.?s new AIDS salvage therapy, Selzentry (maraviroc), a different class of new antiretroviral AIDS drug which had been discussed and presented at the IAS conference.
At menopause, women lose hormone protection against heart (cardiovascular) and kidney (renal) diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity.
Menopausal women are at relatively high risk for memory loss, high blood pressure (hypertension) and diabetes. A decade ago, the standard treatment for these problems was long-term hormone replacement therapy (HRT). Since then, studies have shown that extensive use of HRT is associated with significant adverse effects.
The usefulness of established molecular imaging/nuclear medicine approaches in identifying the “hows” and “whys” of brain dysfunction and its potential in providing immediately useful information in treating depression are emphasized in a study in the August Journal of Nuclear Medicine.
Bones are typically thought of as calcified, inert structures, but researchers at Columbia University Medical Center have now identified a surprising and critically important novel function of the skeleton. They?ve shown for the first time that the skeleton is an endocrine organ that helps control our sugar metabolism and weight and, as such, is a major determinant of the development of type 2 diabetes.
For decades, older women have taken hormone replacements to replenish estrogen and progesterone levels lost to aging. More recently, testosterone (the most important male hormone) supplements have been used by aging men to improve their muscle mass, bone strength, libido and quality of life.
At menopause, women lose hormone protection against heart (cardiovascular) and kidney (renal) diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity. The results of their study, using an animal model, suggest that estrogen depletion can have these effects.
The Summer 2007 issue of the American Heart Hospital Journal explores one of the pivotal issues in cardiology today, the drug-eluting stent. Through commentaries from 10 leading national and international specialists, the issue presents a comprehensive discussion on the explosive growth and the potential risks of DESs.
deCODE scientists have identified a sequence variant responsible for virtually all cases of a major subtype of glaucoma. The protein encoded by the gene appears to have a clear pathophysiologal role.
It may not be inhaled into the lungs, but smokeless tobacco exposes users to some of the same potent carcinogens as cigarettes. In the August issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, researchers at the University of Minnesota Cancer Center report that users of smokeless tobacco are exposed to higher amounts of tobacco-specific nitrosamines — molecules that are known to be carcinogenic — than smokers.
