Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Comparison of antiretroviral therapies shows that tenofovir DF and stavudine are equally effective

Results from a three year double-blinded trial which compared antiretroviral therapies show that the combination regimens of tenofovir DF and stavudine, are equally effective, though tenofovir DF has more favorable outcomes with respect to cholesterol levels and the nervous system.

Gene therapy may provide a treatment for a group of incurable, progressive neurological diseases called polyglutamine-repeat diseases

Researchers from the University of Iowa have have shown for the first time that gene therapy delivered to the brains of living mice can prevent the physical symptoms and neurological damage caused by an inherited neurodegenerative disease that is similar to Huntington's disease (HD).

Treatment of chronic hepatitis C with interferon can be ineffective due to relapse

Treatment of chronic hepatitis C with interferon can be ineffective due to relapse. We aimed to reduce the 40% relapse rate of 6 months interferon–ribavirin combination therapy by prolonging treatment to 18 months.

New research may help doctors diagnose diseases like HIV and hepatitis C earlier

A new method developed by researchers at the National Institute of Standards and Technology for accurately measuring the concentration of artificial viruses in a solution may ultimately help doctors diagnose diseases like HIV and hepatitis C earlier.

Discovery of gene that causes a rare juvenile-onset form of amyotrophic lateral sclerosis (ALS)

The discovery of the Senataxin gene, on chromosome 9q34, may provide clues to the mechanisms of related brain disorders. The study appears in the June 2004 issue of the American Journal of Human Genetics.

Muscular German boy sheds new light on muscle development and genetics

By studying the genetic make up of a German boy born with unusually well developed muscles, an international research team has discovered the first evidence that the gene whose loss makes "mighty mice" also controls muscle growth in people.

Microchip to track genetic signature of cancer and normal tissue

MicroRNAs (miRNAs), tiny pieces of genetic material that can serve as stop signs for gene expression and protein synthesis, are thought to be important in the development of cancer.

New findings may help better understand how harmless viruses can cause severe disease among patients with weakened immune systems

When a major branch of the mouse immune system is disabled, a normally harmless virus can rapidly mutate into a lethal one, according to researchers at Washington University School of Medicine in St. Louis.
