Study: Soap And Water Work Best In Ridding Hands Of Disease Viruses

...teritis and a host of other illnesses. A separate key finding was that waterless handwipes only removed roughly 50 percent of bacteria from volunteer subjects?hands. "We studied the efficacy of 14 different hand hygiene agents in reducing bacteria and viruses from the hands," said Emily E. Sickbert-Ben...

Genetically modified natural killer immune cells attack, kill leukemia cells

...rmally have only weak anti-leukemic activity. The key breakthroughs made by the St. Jude team were the development of a laboratory technique for rapidly producing a large, pure population of NK cells from a small sample of blood; and developing a technique for genetically modifying NK cells so that they...

UCSD researchers maintain stem cells without contaminated animal feeder layers

...s noted that "the identification of activin A as a key factor in mediating these cellular events will help to unravel the biochemical pathways responsible for 'stemness'. An increased efficiency in the generation and culture of human stem cells for potential clinical applications is timely, given the rec...

Nanogen Issued Patent for Electronic Microarray With Memory

... a local memory. This "smart chip" technology is a key feature of Nanogen's NanoChip(R) 400 electronic microarray, the company's second generation multi-purpose system for developing and performing molecular diagnostic tests. Using local memory circuits provides for precise control of the currents deliv...

Researchers trace evolution to relatively simple genetic changes

... many populations, but these changes do not affect key parts of the molecule. In addition, one population in Japan used the same gene to evolve low armor, but has no changes at all in the protein coding region. Instead, Kingsley said, "the mutations that we have found are, we think, in the (gene's) contr...

She has played a key rolein changing the scientific world's understanding of how ocean food websare based on much smaller organisms than previously believed.Wood is an adjunct scientist at the Bigelow Laboratory for OceanSciences and the Harbor Branch Oceanographic Insti...

New SARS Protein Linked To Important Cell Doorway

...eed to develop ways to disable or weaken it. "The key to studying novel viruses used to be the ability to isolate the virus and grow it in a culture," notes lead author Daved Fremont, Ph.D., assistant professor of biochemistry and molecular biophysics and of pathology and immunology. "Now we can take th...

Sanofi pasteur, Swiftwater, PA, manufactured the trial vaccine, which is an inactivated vaccine made from an H5N1 virus isolated in Southeast Asia in 2004. Sanofi...

Scientists document complex genomic events leading to the birth of new genes

...a Ciccarelli, Ph.D., lead author on the study. The key to this, however, is that the duplicated copies of genes very quickly evolve functions that are significantly different than those of their progenitors. Natural selection acts on gene duplications, most often by deleting them from the gene pool or b...

...in also has been found to affect the activity of a key neurotransmitter, dopamine, in the brain, said the researchers. What's more, they found two other genes--PAM and GCH--that are involved in producing PACAP to be upregulated in the treated brain tissue. Brandish and his colleagues said that such find...
