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.

Nucleic acid-amplification testing has improved the safety of the nation's blood supply

State-of-the-art testing systems to screen donated blood have improved the safety of the nation's blood supply by preventing the transmission of potentially deadly viruses, according to a new study funded by the National Heart, Lung, and Blood Institute.

Correlation between HCV viral load and severity of liver disease

The significance of hepatitis C virus (HCV) serum titers (HCV viral load) has been examined in several clinical situations. There is much evidence that patients with a lower viral load have better response rates to anti-viral therapy compared to those with higher levels.

Market research 'World RNAi Markets: Current and Future Outlook'

Gene silencing by RNAi has now been identified as a crucial technology for target validation and therapeutics. By targeting and interfering with messenger RNA (mRNA), RNAi technology blocks the expression of the proteins implicated in disease progression.

DNA left overs, new mechanism for evolution

A team of researchers from the Universitat Autònoma de Barcelona (UAB) has discovered that transposons, small DNA sequences that travel through the genomes, can silence the genes adjacent to them by inducing a molecule called antisense RNA.

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.
