Cure for cancer one step closer

...t findings made achievable by the Tissue Bank will lead to the next big breakthrough in the fight against cancer," she said. "By providing researchers who are part of an ethically and scientifically approved research project with tissue, matching blood samples and full clinical data, valuable funds wil...

Super-fermenting fungus genome sequenced

Jeffries of the Forest Products Laboratory in Madison, Wisconsin. “We are now engineering these genes to increase ethanol production.?Jeffries said that yeast strains like Pichia have evolved to cope with the oxygen-limited environm...

Scientists identify pancreatic cancer stem cells

...st prognosis of any major cancer, said the study's lead author, Diane M. Simeone, M.D., an associate professor of surgery and molecular and integrative physiology. "The cells we isolated are quite different from 99 percent of the millions of other cells in a human pancreatic tumor, and we think that, b...

NIH researchers discover protein that appears to regulate bone mass loss, the cause of osteoporosis

...d loss, but the detailed biological processes that lead to this imbalance are not completely understood. Now researchers at the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), and colleagues are reporting new insights into the biology of bone ...

Biodiesel study targets cleaner air, cleaner engines

... It is hoped that the success of this project will lead to an accelerated adoption of biodiesel use in on-farm applications, not only in Ontario but across Canada. This will bring both environmental and economic benefits to Canadians, since biodiesel can be produced from local, renewable resources. Biodi...

Noise echoes in cell communications

...on for the benefits of noise. Their findings could lead to major improvements in hearing aid technology. Dawei Hong, an assistant professor of computer science, Joseph Martin, a professor of biology, and William Saidel, an associate professor of biology, are working together to explain the biological ben...

Sandia researchers take new approach to studying how cells respond to pathogens

...nvades a body. Understanding the early steps could lead to better ways to diagnose and stop disease before there are symptoms and development of more effective therapeutics. Most existing research into how immune cells respond has been done by looking at large cell populations. The Sandia researchers s...

Transfusion expert urges wider use of filtered blood

...f increased cost. However, Neil Blumberg, M.D., lead author of the study and a proponent of leukoreduction, argues that several cost-benefit analyses show that an upfront increase of $25 to $35 for each unit of filtered blood is offset by savings from less use of antibiotics, reduced patient time in th...

UCI scientists reconstruct migration of avian flu virus

...id Robert Wallace, UCI postdoctoral researcher and lead author of the study. "By spreading across a large area, the virus in essence can run multiple experiments in multiple locations, increasing the likelihood that it will mutate into a form that can be transmitted from human to human." Avian flu has ...

Study suggests some drug resistance to influenza B medications

...s whether suboptimal dosing for these viruses will lead to increased selection of viruses with high-level resistance.? “Influenza viruses evolve rapidly and nimbly, which compels ongoing investigation of antiviral therapies that use alternative mechanisms of action and target different points in the vir...

Helium helps patients breathe easier

Many researchers have studied heat as a potential treatment for cancer, but the difficulty of confining heat within the tumor and predicting an effective heat dose has limited its use. The UC Davis research, carried out in col...

Allergy to hair dye increasing

...ir, warn researchers in this week's BMJ. This can lead to dermatitis on the face and, in severe cases, facial swelling may occur. More than two thirds of hair dyes currently contain para-phenylenediamine (PPD) and other related agents. During the 20th century, allergic reactions to PPD became such a s...
