Dark state and DNA

Chemists at Ohio State University have probed an unusual high-energy state produced in single nucleotides - the building blocks of DNA and RNA - when they absorb ultraviolet (UV) light.

Renegade ribonucleic acid

Researchers at Johns Hopkins have discovered that a tiny piece of genetic code apparently goes where no bit of it has gone before, and it gets there under its own internal code.

Cytogen issued new patent covering oral drug delivery agents

Cytogen Corporation has announced that it has been issued United States patent number 7,135,457 covering its oral drug delivery agents - random peptide compositions that bind to gastro-intestinal tract (GIT) transport receptors.

Whoever said people were much the same was wrong!

An international research team have come up with a new genetic map which could demand a fundamental shift in how we think genes work.

Potential for first diagnostic DNA test to guide antidepressant treatment

Treatment of depression is difficult for both patients and for psychiatrists. While there are numerous drugs available that work, finding the right one -- or right combination -- is, at times, a matter of trial and error.

Built-in blocker - drug and antidote in the same molecule

In cases of serious side effects or overdoses of medications, it can be vital to have a fast-acting antidote on hand.

Study shows how the plague bacteria Yersinia pestis causes disease

The bacteria responsible for the plague and some forms of food poisoning "paralyze" the immune system of their hosts in an unexpected way, according to a new study in the September 8, 2006 issue of the journal Cell.

Variation in 3 genes influences risk of age-related macular degeneration

Researchers in Boston have discovered a new common, noncoding variant in the Complement Factor H (CFH) gene that is associated with age-related macular degeneration (AMD), the leading cause of irreversible visual impairment and blindness among persons aged 60 and older.

Age-related hearing loss may be genetic

Researchers at the University of Antwerp have discovered that hearing loss is linked to flaws in a specific gene.

RNA gene found to be one of the fastest evolving regions in human genome

Since completing the sequencing of the chimpanzee genome last year, geneticists have spent many hours comparing human DNA sequences to those of our closest evolutionary relative, looking for the differences that distinguish the two species.

Global sharing of avian influenza virus samples

OFFLU, the OIE/FAO joint network of expertise on avian influenza, will systematically make avian influenza virus sequences accessible to the entire scientific community.

Scientists identify genetic element that the dengue virus uses to replicate

The first step in the transmission of mosquito-borne viruses is no mystery: it's the pesky insect's bite that allows the virus to enter its victim's bloodstream.

Genes may be responsible for obsessive-compulsive disorder

Obsessive-compulsive disorder tends to run in families, causing members of several generations to experience severe anxiety and disturbing thoughts that they ease by repeating certain behaviors.

HIV mutation clue to why only some people develop AIDS dementia

The study of 18 HIV-positive subjects shows that HIV in the brain and central nervous system is genetically different from HIV that lives in the blood and peripheral tissues.

Gene variant increases risk of type 2 diabetes - but healthy lifestyle changes reduce genetic risk

Researchers have confirmed that a gene variant confers susceptibility to type 2 diabetes in participants of the Diabetes Prevention Program (DPP), a large clinical trial in adults at increased risk for developing type 2 diabetes.

Researchers find protein associated with brain cell death

Neuroscientists at the Case Western Reserve University School of Medicine have found evidence of which protein in the brain's immune cells triggers a cascade of reactions that produces unregulated free radical production that eventually leads to the neural cell death found in Alzheimer's disease.

Common genetic prostate cancer variant identified

Prostate cancer (CaP) is a presumed result of both genetic and environmental events.
