Swiss researchers develop all-in-one remote control gene expression tool

...rned off when the desired effect is achieved, thus preventing unharnessed growth ?otherwise known as cancer. "It's an extremely polymorphic tool, useful in testing therapies and in preclinical studies," says Trono. "Using it we can control the gene expression in vivo in an extraordinary and sensitive way." ...

Antioxidant selenium offers no heart-disease protection

...in particular, that were thought to play a role in preventing heart disease based on observational studies have turned out not to be protective in randomized clinical trials, and selenium now has joined this group. The main findings of this report focus on the 1,004 participants in the study, conducted from 1...

Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

The study involved 98 infants who presented to Children's Hospital of Pittsburgh's Emergency Department with one of...

Anthrax inhibitor counteracts toxin, may lead to new therapeutics

...tion of the journal Nature Biotechnology, works by preventing the assembly of toxic enzyme components, thereby blocking the formation of fully assembled anthrax toxin and neutralizing its activity. The inhibitor protected rats from anthrax toxin in the study. "Our eventual goal is to use the inhibitor as a hu...

Medical experts: US unlikely to have enough vaccines to stop avian flu

... Unfortunately, the efficacy of such strategies in preventing the spread of infectious diseases has not been extensively studied, Bruine de Bruin said. Although the federal government has expressed a commitment to open communication about these risks, its messages have not yet been scientifically evaluated, acc...

Aspirin reduces cardiovascular risks in men and women -- but differently

...ny of the past studies of the effect of aspirin in preventing cardiovascular events looked only at men, so physicians were reluctant to prescribe aspirin for women because there was little data," Berger continued. "But now, the combined data of recent trials involving women demonstrates that women can benefit j...

Scientists discover basic defect in cystic fibrosis airway glands

...sticky mucus can also block tubes in the pancreas, preventing digestive enzymes from reaching the small intestine. The disorder results from mutations in the gene for the cystic fibrosis transmembrane conductance regulator (CFTR), a membrane channel regulator essential for proper salt and water movement across...

Scientists reveal how deadly toxin hijacks cells

...xin enters neurons by binding to nerve endings and preventing the release of crucial chemical messengers, known as neurotransmitters, that communicate with muscles. When enough nerve endings are invaded, botox can lead to paralysis and death. By capitalizing on the ability of botox to act on a localized group ...
