Solving the puzzle of cognitive problems caused by HIV infection Posted: 01 Jul 2011 12:05 PM PDT A longstanding medical mystery -- why so many people with HIV experience memory loss and other cognitive problems despite potent antiretroviral therapy -- may have been solved by researchers.

Foods with baked milk may help build tolerance in children with dairy allergies, study suggests Posted: 01 Jul 2011 12:04 PM PDT Introducing increasing amounts of foods that contain baked milk into the diets of children who have milk allergies helped a majority of them outgrow their allergies, according to a new study.

Copper reduces infection risk by more than 40 per cent, experts say Posted: 01 Jul 2011 10:22 AM PDT Medical researchers have presented research into the mechanism by which copper exerts its antimicrobial effect on antibiotic-resistant organisms.

Sport performance follows a physiological law; Study suggests peak at 20-30 years of age, then irreversible decline Posted: 01 Jul 2011 10:22 AM PDT Researchers in France have published research describing the evolution of performances in elite athletes and chess grandmasters. Their findings suggest that changes in individual performance are linked to physiological laws structuring the living world.

New class of antiangiogenesis drugs: Natural plant compound blocks blood vessel growth by interfering with cellular adhesion Posted: 01 Jul 2011 09:18 AM PDT Researchers have discovered the first of an entirely new class of anti-angiogenesis drugs -- agents that interfere with the development of blood vessels. The investigators describe how a compound derived from a South American tree was able, through a novel mechanism, to interfere with blood vessel formation in animal models of normal development, wound healing and tumor growth.

Mutations can spur dangerous identity crisis in cells Posted: 01 Jul 2011 09:15 AM PDT A new study brings scientists one step closer to developing treatments for issues associated with aging or chronic diseases in which cells lose their ability to maintain a stable pattern of gene expression.

Dentists' role in painkiller abuse Posted: 01 Jul 2011 09:15 AM PDT Dentists, pharmacists and addiction experts provides new research and recommendations to help dentists combat, rather than contribute to, abuse of addictive painkillers.

Treatment approach to human Usher syndrome: Small molecules ignore stop signals Posted: 01 Jul 2011 09:15 AM PDT Researchers have now developed a new Usher treatment approach. Usher syndrome is the most common form of combined congenital deaf-blindness in humans and affects 1 in 6,000 of the population.

Gastric bacterium Helicobacter pylori protects against asthma Posted: 01 Jul 2011 09:15 AM PDT Infection with the gastric bacterium Helicobacter pylori provides reliable protection against allergy-induced asthma, immunologists have demonstrated in an animal model. Their results confirm the hypothesis recently put forward that the dramatic increase in allergic diseases in industrial societies is linked to the rapid disappearance of specific micro-organisms that populate the human body.

Key immune substance linked to asthma, Stanford study finds Posted: 01 Jul 2011 09:15 AM PDT Medical researchers have linked a master molecule of the immune system, gamma-interferon, to the pathology of asthma, in a study of mice.

Potential of simple injection on patients with head injury Posted: 30 Jun 2011 07:00 PM PDT New research has suggested that tranexamic acid has the potential to prevent people dying from head injuries. It is a cheap, off-patent drug with the potential to help people suffering from brain trauma.
