Access to antiretrovirals unlikely to reduce HIV infection rates

... College London) suggests that the HIV epidemic in poor countries will not be controlled through antiretroviral drugs alone, even if universal access is achieved. As they demonstrate in an article in the open-access international medical journal PLoS Medicine, without additional prevention methods such as...

St. Jude projects 90 percent cure rate for ALL

...ican-American children, Pui noted. They still have poor outcomes in national studies, but studies at St. Jude have shown African-American children have the same high cure rates as white children when given access to the same effective treatments. "This reflects the ability of St. Jude to provide free tre...

Do plants have the potential to vaccinate against HIV?

The results could also lead to the development of more effective vaccines. By using specific immunoglobulin sequences in the fusion molecule, antigens could be...

Measuring artery repair cells could become new heart disease test

...hers have shown that -- while risk factors such as poor diet, smoking, high cholesterol levels and inactivity are important in the development of atherosclerosis --the disease progresses as the body's loses its intrinsic ability to repair and rejuvenate itself. Current methods for measuring EPCs ?which c...

Males with elevated levels of testosterone lead shorter lives but have more success siring offspring

...r ability to attract older females, it resulted in poor reproductive performance. "Although testosterone increased male fitness, as measured by lifespan and number of offspring, the extended effects on offspring and female mates were generally negative and may ultimately constrain the evolution of highe...

Pennsylvania researchers find liver transplants provide metabolic cure for rare genetic disease

VCU Massey Cancer Center researchers identify a new class of anti-cancer drugs based on platinum

... the study. "Resistance to current drugs is due to poor cellular absorption and an increased ability of the cell to process or repair the damage caused by the chemotherapeutic agent." "Our novel compound was designed to overcome resistance by emphasizing new modes of DNA binding, and in the process we ha...

New MRI technique quickly builds 3-D images of knees

... which yield high resolution in a single plane and poor resolution in the remaining direction, he says. To capture an image, a magnetic resonance scanner commonly conducts hundreds to thousands of little "experiments," or encodings, that help to make up the big picture.

Researchers add crucial information on how the body's T cells react to parasitic diseases

...arasite to parasite--making this set of proteins a poor choice for vaccine development, Tarleton said. The importance of the new research, however, isn't in specifically what happens in T. cruzi and Chagas Disease. Rather, it is a new understanding of how T cells react to infection in all parasitic dis...

'Signature' of chromosome instability predicts cancer outcomes

...that this genetic profile, or signature, predicted poor clinical outcome in 12 of the populations studied. The study was published online by the journal Nature Genetics on August 20. "Chromosomal instability is one of the key mechanisms that keeps malignant cell proliferation going," says Zoltan Szallas...

Study links high levels of nitric oxide to infertility and sperm DNA damage

... Most of the infertile men had low sperm counts or poor sperm motility. They measured levels of NO and used a test that can detect DNA damage and repair in individual cells (single cell gel electrophoresis (comet) assay) to determine DNA damage. "We found that the NO levels in the infertile men were, on ...

'Sticky' mice lead to discovery of new cause of neurodegenerative disease
