Access to antiretrovirals unlikely to reduce HIV infection rates

... viral load. Because antiretrovirals therapy (ART) slows AIDS progression and reduces viral load in infected individuals, the drugs not only improve the health and prolong the life of those who take them, but also make it less likely that they infect others. As a consequence, ART has been discussed not onl...

Basic research leads to a novel cancer therapy

...that blocking blood vessel development in a tumour slows down its growth, and shrinks its tissue. This fundamental principle led to the development of SUTENT®, whose active ingredient is Sunitinib. SUTENT® was recently approved for clinical use in the United States, and it is expected to be brought onto th...

UCLA scientists find male gene in brain area targeted by Parkinson's

...he cells die off, they produce less dopamine. This slows the delivery of messages from the brain to the rest of the body, leaving the person unable to initiate or control their physical movements. The condition eventually leads to paralysis. "For the first time, we've discovered that the brain cells that ...

How 'Dirt' Could Educate The Immune System And Help Treat Asthma

...rease, the density of the water decreases and thus slows the ocean thermohaline circulation, so the ocean's ability to absorb carbon dioxide also decreases. This leaves more carbon dioxide in the atmosphere, exacerbating the problem. "At the same time, the reduced ocean circulation will decrease the ocean...

Climate change will affect carbon sequestration in oceans, model shows

Complex gene interactions account for autism risk

...nd that the brain mechanism that normally stops or slows nerve impulses contributes to the disease. The team's findings implicate the so-called GABA receptor genes, which are genes that code for key components of "off switches" in the brain's neurons. GABA, or gamma aminobutyric acid, is a neurotransmitte...

Muscle repair: Making a good system better, faster; implications for aging, disease

... be stymied. Furthermore, as we age, muscle repair slows noticeably, and in Duchenne Muscular Dystrophy and other degenerative muscle diseases, normal repair functions can't cope with disease progression. Researchers from the University of Illinois-Chicago (UIC) and University of Michigan report that whil...

Discovery of T-cell 'traffic control' boosts new drug promise

...ut a drug such as FTY720 controls S1P function and slows the rush of T cells to the transplantation site without blocking normal immune response against bacteria and other infectious agents," he says. Similarly, such a drug should slow the autoimmune response that occurs in MS, a hypothesis recently confir...

IMF Launches World’s First DNA Database for Myeloma Patients

...alia, who lose out because the size of their organ slows them down, making them ripe for capture by larger fish. Brian Langerhans, Washington University biology graduate student in Arts & Sciences, has performed studies on mosquitofish (guppy-like fish, about an inch long) and found that female mosqui...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

... the cell senses that its DNA has been damaged, it slows down the degradation of p53, so that p53 protein levels can rise and initiate protective measures. When higher than normal levels of p53 tumor suppressor exist, there is enough p53 to bind to many regulatory sites in the cell's genome to activate the...

FDA Approves New Treatment for Chronic Hepatitis B

...hronically infected with the HBV virus. Baraclude slows the progression of chronic hepatitis B by interfering with viral reproduction. FDA based its approval of Baraclude on the results of three studies in which Baraclude was compared to another anti-viral drug, lamivudine. In all three clinical studies...

U-M team recovers ancient whale in Egyptian desert

...During a hibernation-like state, cellular activity slows to a near standstill, which reduces dramatically an organism's need for oxygen. If such temporary metabolic inactivity ?and subsequent freedom from oxygen dependence ?could be replicated in humans, it could help buy time for critically ill patients o...

Buying Time Through Hibernation on Demand

Research on Worms Yields Clues on Aging

When exposed to drugs used to treat epilepsy inhumans, worms lived longer and retained youthful functions longer thannormal.Because the ...
