Fat screen delivers plant-derived chemical with antidiabetic effects

..., more generally, provides validation for fat cell screens as a promising strategy for identifying new metabolic drugs, according to the researchers. While harmine itself has effects on the central nervous system that may preclude its use, "it may eventually be possible to separate the nervous system and ...

Scientists seek useful traits in wild cottons

...a Castillo, Experiment Station research assistant, screens cotton grown hydroponically ?without soil ?for salt tolerance. Seedlings are incrementally subjected to different concentrations of salt, which can reach 30,000 parts per million. If cotton breeders can impart more salt tolerance to commerci...

Scientists identify a candidate gene for osteoporosis

...iversity. "We will also be able to develop genetic screens to identify individuals who are at risk for osteoporosis." According to the National Osteoporosis Foundation, osteoporosis affects 55% of Americans over the age of 50. Low bone mineral density (BMD)—the primary indicator of osteoporosis—is influe...

Mayo researchers discover HIV dependence on a human protein

...t to factor such potential potency into designs of screens for additional key cellular proteins that HIV either appropriates as partners, as in the case of p75, or schemes to evade. Quite a few more likely exist. The challenge is to use the right methods to find them." How HIV Infects Humans -- Cannot Curr...

Using nature's most primitive anti-viral defense system to find new approaches to cancer research

...s. "By combining the benefits of Drosophila RNAi screens with the functional analysis in human cell culture models of metastasis, we expect to identify novel, conserved proteins involved in cell migration and invasion, some of which could prove to be good anti-cancer drug targets." According to Dr Mark ...

...chia coli. "If you've got this on tiles or shower screens you don't need so many chemical agents," says Professor Amal. So far the team has been working at laboratory scale. "It's probably a year before we can talk to industry and test outside the lab," says Professor Amal. ...

Device traps, disables harmful bacteria

...gh volume of air and puts it through a filter that screens bacteria and even smaller particles," said Angenent, a member of Washington University's Environmental Engineering Science Program. " And after the filter there is UV light; if something passes through the filter, the UV zaps it. It's a combination a...

Function of new cancer genes discovered

...otein CYLD. Nijman and his colleagues used genetic screens to discover the molecular mechanism underlying cylindromatosis. Nijman's research revealed that the CYLD protein plays an important role in the NF-kappa B signalling route. This is a cellular communications system which becomes overactive if the CYLD...

Researchers discover chemical compounds that affect plant growth

... direction of plant growth due to gravity. Further screens reduced this number to 34, then down to 4 chemicals, which affected gravitropism and the movement of proteins through membranes within the plant cell. . Only one of these resembled auxins, a plant-produced growth hormone involved in gravitropic resp...

UCLA Study Shows One-Third of Drug Ads in Medical Journals Do Not Contain References Supporting Medical Claims

...ng to the authors, the Federal Drug Administration screens the drug ads for validity, but the sheer volume makes it difficult to adequately check many of the ads. For example, in 2002, the FDA screened more than 34,000 ads. Journals included in the study: American Journal of Psychiatry, Annals of Emergency ...
