Affymetrix Unveils Plans to Double Plant and Animal Genome Microarray Offering

...s,Affymetrix is putting GeneChip technology within reach of virtually anyresearch community," said Lianne McLean, Director, Gene ExpressionMarketing at Affymetrix. "We had great success with this program lastyear. By providing the plant and animal community groups with a single,standardized platform for ge...

Bacteria collection sheds light on urinary tract infections

... than men because it is easier for the bacteria to reach their bladder. Fifty percent of all women will experience at least one episode of UTIs during their lifetime. UTIs are typically treated with antibiotics. The researchers found that the E.coli causing the UTIs matched genetically with a sample of E....

“Nano-scissors?laser shows precise surgical capability

...issue andallowed the neurons to grow a new axon to reach the muscle. Until now,researchers have only been able to investigate nerve regeneration inmice and zebrafish, which have complex nervous systems. This laserallows researchers to study nerve cells at their most basicevolutionary form, opening the door...

Novel Enzyme Shows Potential As An Anti-HIV Target

...ene expression. Without Tat, HIV transcripts don’t reach full length and can’t effect viral replication. In a new study, Melanie Ott and colleagues identify an enzyme that regulates viral transcription by modifying Tat. The regulation of HIV genes depends on a complex interplay between proviral DNA, cellu...

Gene variations explain drug dose required to control seizures

...for patients with epilepsy and their physicians to reach an effective dose of the medications that control seizures, said David Goldstein, Ph.D., director of the IGSP Center at Duke University Medical Center and senior author of the study.

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...order called Pompe disease usually die before they reach the age of two. The researchers also said their approach of targeting corrective genes to muscles may have application in treating other muscular dystrophies. Patients with Pompe disease have a defect in a key enzyme that converts glycogen, a stored...

First real-time view of developing neurons reveals surprises, say Stanford researchers

... an age when the nerves first grow from the eye to reach the brain. Then, with the aid of a 6-foot-long laser and some fancy microscopy, the researchers were able to watch individual neurons as they matured in real time. The pair specifically monitored hundreds of neurons in the region of the brain that r...

New Breast Cancer Test Could Save Lives

...age through dense breast tissue, and therefore can reach a far wider section of women than X-ray mammography can. Women below 50 in particular will benefit from this new test, which is much more reliable than X-rays at detecting cancer in this age group. The test is also a much more comfortable procedure ...

Simple drug has the potential to save many lives threatened by malaria

... given to children with severe malaria before they reach hospital, has the potential to save many lives, say researchers in this week's BMJ. Every year over a million children die of malaria in Africa. The majority of fatalities occur outside hospital, especially in rural areas. For those who do make it t...

Although research capacity has grown by leaps and bounds as a result of computer and sensor technology, valuable collections of biological, oceanographic and geologic data from public and private institutions have...

Great White shark evolution debate involves WSU Lake Campus geology professor

... Ciampaglio said the Great White sharks, which can reach a size of nearly 25 feet and possess two-inch teeth, have been a major research subject of his for the past four years. He holds a doctorate from Duke in paleontology, the study of prehistoric life forms. His academic background also includes master'...

No relief for Pacific Northwest drought

...riencing will only get worse in coming months, and reach levels that were generally seen during the Dust Bowl of the 1930s," said Ronald Neilson, a bioclimatologist with the U.S. Forest Service and professor of botany at OSU. Severe drought does not automatically translate into major fires, said Neilson a...

50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

...potassium ions build up within the cell. When they reach a threshold level, the cell is primed for activity, such as transmitting a nerve impulse. Sumoylation has recently been recognized as an important mechanism of cellular activity but until now its 60-or-so known targets were primarily nuclear protein...

Researchers discover chemical compounds that affect plant growth

Combined with the formidable genetic mapping and information available from the Arabidopsis plant, chemical...

Survey finds silver contamination in North Pacific waters
