Treatment with hormones improves visual memory of postmenopausal women
Many women experience declines in their memory during and after menopause, a change thought to be due, in part, to the rapid hormonal changes they weather during that time. Now, research from the University of Michigan Health System suggests that hormone therapy might help women retain certain memory functions. In a study in the new issue of The Journal of Clinical Endocrinology & Metabolism, they report that a group of postmenopausal women showed more brain activity during a visual memory test than did women who were not taking the hormone therapy.

Sleep Apnea Treatment Curbs Aggression in Sex Offenders
Obstructive sleep apnea (OSA) affects up to 20% of men in western cultures, 5% of whom experience significant physical symptoms. A study published in Journal of Forensic Sciences finds that sex offenders who suffer from OSA experience more harmful psychological symptoms than do sex offenders with normal sleep patterns.

The test is based upon DNA-gold nanoparticle technology, and can be packaged in user-friendly kits similar to those used for home pregnancy tests.

Keeping A3G in action represents a new way to attack HIV
For years researchers have been trying to understand how a few HIV-infected patients naturally defeat a virus that otherwise overwhelms the immune system. Last year, a research team at the University of Rochester Medical Center confirmed that such patients, called long-term non-progressors, maintain higher than normal levels of the enzyme called APOBEC-3G (A3G) in their white blood cells, which function to stave off infections. Now, the same group has teamed up with a structural biologist to provide the first look at the A3G structure. Such information represents an early step toward the design of a new class of drugs that could afford to all the same natural protection enjoyed by few, according to a study published today in The Journal of Biological Chemistry.

Fighting HIV With HIV Virus Itself
Researchers at the University of Pennsylvania School of Medicine report the first clinical test of a new gene therapy based on a disabled AIDS virus carrying genetic material that inhibits HIV replication. For the first application of the new vector five subjects with chronic HIV infection who had failed to respond to at least two antiretroviral regimens were given a single infusion of their own immune cells that had been genetically modified for HIV resistance.

Children�s Belly Fat Increases More Than 65 Percent
Abdominal obesity increased more than 65 percent among boys and almost 70 percent among girls between 1988 and 2004. The finding of growing girth is significant because abdominal obesity has emerged as a better predictor of cardiovascular disease and type 2 diabetes risk than the more commonly used Body Mass Index, a weight to height ratio that can sometimes be misleading.

Hormone therapy does not improve quality of life for women
A postmenopausal hormone therapy trial conducted in Estonia indicates that hormone therapy does not improve women's quality of life. The group receiving hormones and the comparison group showed no differences in general quality of life. Only those women that experienced hot flashes and night-time sweating reported beneficial effects. These results were obtained from the Estonian Postmenopausal Hormone Therapy trial (EPHT) funded by the Academy of Finland and conducted under the leadership of Research Professor Elina Hemminki from the National Research and Development Centre for Welfare and Health (Stakes).

How cells adhere so firmly to blood vessel walls
Blood is the universal means with which different types of cells are transported in our bodies. Its movement is determined by hydrodynamic forces. The cells anchor themselves to the walls of the blood vessels in the target tissue with the aid of special adhesive molecules, which are also called receptors. In many cases these receptors are grouped in the cell surface in nanometer-sized patches. The adhesion process is based on the key and lock principle: as a rule, an adhesion molecule only bonds with specific partners. This guarantees that the cells are only brought to a halt where they are to fulfill their biological function.

Researchers have used a single compound to increase the lifespan of obese mice, and found that the drug reversed nearly all of the changes in gene expression patterns found in mice on high calorie diets--some of which are associated with diabetes, heart disease, and other significant diseases related to obesity. The research, led by investigators at Harvard Medical School and the National Institute on Aging, is the first time that the small molecule resveratrol has been shown to offer survival benefits in a mammal. The study is reported in the November 1 advanced online edition of Nature.
