Widespread antiviral drug use can accelerate the evolution of drug resistance in viruses

Influenza's ability to resist the effects of cheap and popular antiviral agents in Asia and Russia should serve as a cautionary tale about U.S. plans to use the antiviral Tamiflu in the event of widespread avian flu infection in humans, scientists say.

Clioquinol - gastrointestinal drug could become anti-aging treatment

Recent animal studies have shown that clioquinol – an 80-year old drug once used to treat diarrhea and other gastrointestinal disorders – can reverse the progression of Alzheimer's, Parkinson's and Huntington's diseases.

New understanding of ion channels in the body

A discovery by Canada-U.S. biophysicists will improve the understanding of ion channels, akin to little 'nano-machines' or 'nano-valves' in our body, which when they malfunction can cause genetic illnesses that attack muscles, the central nervous system and the heart.

Key survival circuit discovered in Salmonella bacteria

Hundreds of trillions of bacteria make their home in the vertebrate gut. Though many of these microbes perform helpful duties for their host, others - the pathogens - are unwelcome visitors, causing disease.

Vaxfectin-formulated H5N1 pandemic influenza achieves T-cell responses and cross-clade reactivity in humans

Vical Incorporated has announced that the company's Vaxfectin-formulated H5N1 pandemic influenza DNA vaccines induced T-cell responses against a matching strain of influenza virus and demonstrated cross-clade antibody responses against a different strain in a Phase 1 clinical trial.

New set of controls for stem cells discovered

Natural changes in voltage that occur across the membrane of adult human stem cells are a powerful controlling factor in the process by which these stem cells differentiate, according to research published by Tufts University scientists.

Surface analysis exposes counterfeit medicines

CERAM Surface and Materials Analysis has published a white paper highlighting how surface analysis can expose counterfeit medicines. It describes how technologies such as X-ray photoelectron spectroscopy (XPS) and Time-of-Flight Secondary Ion Mass Spectroscopy (ToFSIMS) are being used in novel ways to not only analyse the composition of various pharmaceuticals, but also to determine differences in the manufacturing processes involved.

Study specifies chemical pathway for ions through the cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charged particles, or ions, follow across cell membranes.
