...virus infects cells. The information could also be helpful in identifying potential weak points that can be exploited by novel antiviral drugs or vaccines. The SARS (severe acute respiratory syndrome) coronavirus was responsible for a worldwide outbreak in 2002-2003 that affected more than 8,000 people and...

Firefly protein lets researchers monitor molecule linked to cancer

... addition, they showed that the system is not only helpful for learning if a drug is having the desired effect, it can also be used to fine-tune drug dosage for maximum benefit. "One of the reviewers of our paper suggested that we should use the system to produce a full dose-response curve, which helps esta...

NIEHS launches website with information for assessing environmental hazards from Hurricane Katrina

Genetic analysis of Asian elephants in India reveals some surprises

...pulation genetic studies of other species would be helpful in corroborating whether the Palghat Gap and the Brahmaputra River have served as important biogeographical barriers to a broad range of taxa and thus should be considered in future conservation planning." The Asian elephant (Elephas maximus) is rec...

The bioweapon is in the post

...ulligan, president of Blue Heron, says it would be helpful to have a list of "select sequences" that are off-limits for gene synthesis without explicit government permission, rather than having to make difficult judgments based on the list of select agents. "Tell us what we can't make," he implores. But wit...

According to the U.S. Centers for Disease Control and Prevention, 95 percent of adult Americans suffer from tooth decay. Considered by the U.S. surgeon general to be a "silent epidemic," tooth ...

Scientists directly view immune cells interacting to avert autoimmunity

...arly stage of an autoimmune attack, it may be very helpful to direct the therapeutic regulatory T cells to the lymph nodes so they interact with dendritic cells before the autoimmune T cells are able to, and thereby "stamp out the initial sparks" before the disease spreads to the tissue. Krummel notes tha...

Newly discovered protein kills anthrax bacteria by exploding their cell walls

...l many different kinds of bacteria, including many helpful species. Because it is so specific, the chances of anthrax becoming resistant to PlyPH, as it is to many of the antibiotics currently available to treat it, are extremely low. "We have never seen bacterial resistance to a lysin," says Fischetti. "Pl...

A Jekyll and Hyde of cytokines: IL-25 both promotes and limits inflammatory diseases

...IL-25 has a Jekyll and Hyde personality: it can be helpful or hurtful depending on how it interacts with T helper cells, a subset of immune cells that influences inflammatory responses," said David Artis, an assistant professor in Penn's Department of Pathobiology and senior author of the study.
