HIV Infection Prematurely Ages The Brain

HIV infection or the treatments used to control it are prematurely aging the brain, researchers at Washington University School of Medicine in St. Louis and the University of California-San Diego have found. Blood flow in the brains of HIV patients is reduced to levels normally seen in uninfected patients 15 to 20 years older, scientists report online in The Journal of Infectious Diseases. "The graying of the AIDS patient community makes this infection's effects on the brain a significant source of concern, " says first author Beau Ances, M.D., Ph.D., assistant professor of neurology at Washington University. "Patients are surviving into their senior years, and a number of them are coming forward to express concerns about problems they're having with memory and other cognitive functions.

Coping With Common Digestion Problems

You know you are getting older when the word heartburn starts finding its way into your vocabulary. When the pizza you had late last night is still with you the next morning. This is when you know you are starting to have regular digestion problems. Most people do not want to discuss these problems, and they will suffer in private. However, what they may not realize is that these problems are exceedingly common. About 9 out of 10 people their same age suffer from some of the same problems. For most suffers solving these problems will be easy, for others it will take a bit more work. In most cases it is a straightforward matter of making small lifestyle changes.

Virus Replication Seen On Video Is Faster Than Thought Possible

New video footage of a virus infecting cells is challenging what researchers have long believed about how viruses spread, suggesting that scientists may be able to create new drugs to tackle some viruses. Previously, viruses were thought to spread by entering a cell, replicating there, and then being released to infect new cells, so that the rate of spread of a virus would be limited by how quickly it could replicate in each cell. However, a virus called vaccinia spreads in a different and much faster way, according to a new study in the journal Science by researchers from Imperial College London, funded by the Medical Research Council.

Hypoglycemia - Your Body, Sugary Foods and the Liver - Part 2

Hypoglycemia can be a result of pancreatic malfunction, frequently caused by food allergies (possibly to simple sugars). Carbohydrates in the form of fruits are absorbed more slowly, due to their more complex nature, and do not burden the pancreas. If you are hypoglycemic, it may help to supplement with L-Glutamine. As long as you are lacking certain amino acids in your diet, your body will continue to crave the foods you were addicted to (most food allergies create chemical imbalances which become addictions). The bottom line is to get back to basics. Ideally, a person should get 75% of their calories from, at least, 5-6 servings of fresh organic in-season fruits and vegetables and 25% from organic proteins.

Hypoglycemia - Your Body, Sugary Foods and the Liver - Part 3

Let your body be your final guide. After you have broken the addictions and have followed all of the recommendations you can for your blood, ancestry or geno type, you will be able to customize a diet that is specifically yours. At that point, there may only be a few foods that remain in your diet that shouldn't be eaten. If you are aware of your body's reactions (upset stomach, bleeding gums, headaches, sugar rushes or crashes, etc.), you will be able to pinpoint the offending foods and replace them with better alternatives. As your lifestyle improves, your body will start to heal itself. First, the body will begin to detoxify; it will be out with the old and in with the new.

European Medicines Agency Updates On Pandemic Influenza

The Agency's Committee for Medicinal Products for Human Use (CHMP) recommended the granting of a conditional marketing authorisation for a fourth pandemic vaccine, Arepanrix from GlaxoSmithKline Biologicals. This recommendation was made using an emergency procedure which fast-tracks evaluation of new vaccines developed during a pandemic. Information on Arepanrix was evaluated in an accelerated timeframe using a rolling review which started with the submission of the first available data on 17 July 2009. Further clinical studies in children, adolescents and adults are ongoing and results will become available from March 2010 onwards. The Committee also reviewed further data on the three centrally authorised pandemic influenza vaccines Celvapan, Focetria and Pandemrix and the antiviral Tamiflu.
