Baseline Dopamine Levels And Our Motivation To Eat Influenced By Fat Hormone
As we all know from experience, people eat not only because they are hungry, but also because the food just simply tastes too good to pass up. Now, a new study in the August 6th Cell Metabolism, a Cell Press publication, helps to explain how leptin, a hormone produced by fat tissue, influences that motivation to eat.

California HIV/AIDS Advocates To Appear At Hearing On Proposed Budget Cuts
On Friday, HIV/AIDS advocates in California will appear at the state Legislature"s Budget Conference Committee hearing to urge lawmakers to block proposed health-related budget cuts, the Bay Area Reporter reports. According to the Reporter, Gov. Arnold Schwarzenegger"s (R) latest budget proposal includes cutting $67.8 million from state HIV programs and an additional $12.3 million from the AIDS Drug Assistance Program. Anne Donnelly of Project Inform said, "We realize we may have to take cuts to our programs. But let"s make sure they are minimized and that we continue to deliver the essential services to those people living with HIV and those also at risk." Next week HIV/AIDS advocates also plan to convene on the steps of the state Capitol to protest the proposed budget cuts (Bajko, Bay Area Reporter, 6/4).

Results From Trials Of DHA In Alzheimer's Disease And Age-Related Cognitive Decline

Results from two large studies using DHA, an omega 3 fatty acid, were reported at the Alzheimer"s Association 2009 International Conference on Alzheimer"s Disease (ICAD 2009) in Vienna. One of the trials was conducted by the Alzheimer"s Disease Cooperative Study (ADCS) supported by the U.S. National Institute on Aging (NIA), and the second by Martek Biosciences Corporation. The NIA trial lasted 18 months and was conducted in people with mild to moderate Alzheimer"s. Martek"s trial was six months, and was conducted in healthy people to see its effect on "age related cognitive decline" Both studies used Martek"s algal DHA. The results of the ADCS trial show no evidence for benefit in the studied population. The Martek trial showed a positive result on one test of memory and learning, but that study was in healthy older adultswith mild memory complaint, not people with Alzheimer"s or another dementia. The results need confirmation. "These two studies - and other recent Alzheimer"s therapy trials - raise the possibility that treatments for Alzheimer"s must be given very early in the disease for them to be truly effective," said William Thies, PhD, Chief Medical & Scientific Officer at the Alzheimer"s Association. "For that to happen, we need to get much better at early detection and diagnosis of Alzheimer"s." DHA (docosahexaenoic acid) is the most abundant omega 3 fatty acid in the brain. Previous animal studies and epidemiology in humans suggested that DHA may be beneficial in people with Alzheimer"s. The studies reported at ICAD 2009 were: -- Joseph Quinn, et al - A clinical trial of docosahexaenoic acid (DHA) for the treatment of Alzheimer"s disease. -- Karin Yurko-Mauro, et al - Results of the MIDAS Trial: Effects of Docosahexaenoic Acid on Physiological and Safety Parameters in Age-Related Cognitive Decline. The 2009 Alzheimer"s Association International Conference on Alzheimer"s Disease (ICAD 2009) brings together more than 3,000 researchers from 70 countries to share groundbreaking research and information on the cause, diagnosis, treatment and prevention of Alzheimer"s disease and related disorders. ICAD 2009 will be held in Vienna, Austria at Messe Wien Exhibition and CongressCenter from July 11-16. The Alzheimer"s Association is the leading voluntary health organization in Alzheimer care, support and research. Our mission is to eliminate Alzheimer"s disease through the advancement of research, to provide and enhance care and support for all affected, and to reduce the risk of dementia through the promotion of brain health. Our vision is a world without Alzheimer"s. For more information, visit www.alz.org. Alzheimer"s Association
