Cure for cancer one step closer

...his week. There is every possibility that 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 an...

Biodiesel study targets cleaner air, cleaner engines

...renewable resources. Biodiesel is a renewable fuel made from locally available sources, including animal fats and plant oils such as soybean, sunflower and canola. During normal farm field work, a research team from Agriculture and Agri-Food Canada tested both pure and blended biodiesel, in which the...

Transfusion expert urges wider use of filtered blood

... combine all of the safety measures that have been made to the blood supply since the AIDS epidemic, all of those safety adjustments combined are is still less beneficial to patients than the benefits of leukocyte reduction," Blumberg said. Transfusions are done routinely, and some practitioners are no...

...pothesis of human-manufactured landscapes has been made popular by Charles Mann’s book - 1491: New Revelations of the Americas Before Columbus ?and could influence conservation policy in the Americas. That millions of people once populated the Americas, and that in Amazonia, at least, the rainforest is th...

Scientists genetically engineer tomatoes with enhanced folate content

...ate. So, in 1998, the Food and Drug Administration made it mandatory that many grain productssuch as rice, flour and cornmeal be enriched with a synthetic form of folate known as folic acid. Folate deficiencies remain a problem in many underdeveloped countries, however, where adding folic acid is impra...

Gut research yields new anti-cancer approach

... a basic process in tumor growth. Microtubules are made of two related proteins, alpha and beta tubulin, which pair up to form a chain and then wind into a helix. The current studies found that high-dose PPARgamma inhibitors reduced levels of alpha and beta tubulin by 60 to 70 percent. Also described in t...

The results of the study were published recently in the American Journal of Respiratory Critical Care Medicine. Patients with COPD have difficulty breathing out...

Mechanism of nicotine's learning effects explored

...euron, published by Cell Press. The researchers made their discoveries by analyzing the electrophysiological properties of neurons in slices of mouse brain, as they treated the slices with nicotine or with drugs that prevent nicotine’s action. Specifically, the researchers studied the neurons of the pr...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

...lifornia, San Diego (UCSD) School of Medicine have made a breakthrough in identifying functional elements in the human genome, according to a report published online today in Nature Genetics. While the DNA sequence can identify genes (the 'what') within the genome, it cannot answer the more fundamental ...

Gene tests and brain imaging reveal early dementia

...ose Alzheimer's with any certainty, but things are made easier if you know who runs the greatest risk," she says. "If genetic mapping, MRI and cognitive tests all suggest approaching Alzheimer's, it might be an idea to start a course of treatment." ...

Changes in amino acids in the 1918 influenza virus cut transmission

...which was artificially created in a laboratory and made to look like avian flu. One virus bound to only alpha-2,6, the second bound to both, and the artificially-generated virus bound to only alpha-2,3. The researchers were surprised to discover that the ferrets infected with all three viruses, includ...

Need oxygen? Cells know how to spend and save

...ow oxygen, liver, uterus, lung and colon cells all made COX4-2. The researchers then exposed mice to hypoxia for a few weeks and found that they too showed increased levels of COX4-2. In 1992, Semenza's team had discovered a protein which they called HIF-1 (for hypoxia-inducible factor 1) that cells m...

The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better

...aging Lab at Children’s Stem Cell Research Center, made the discovery while working with a population of stem cells they isolated in the lab while searching for a cure for Duchene muscular dystrophy (DMD). DMD is a genetic disease estimated to affect one in every 3,500 boys. Patients with DMD lack dystrop...

MIT model helps researchers 'see' brain development

...d with Fischl's team to ensure that their analyses made sense clinically. “We can't open the brain and see by eye, but the cool thing we can do now is see through the MR machine,?a technology that is much safer than earlier techniques such as X-ray imaging, said Yu. The first step in analyzing these...

Metacognition: Faced with a test, rats can check their knowledge first

...ssing metacognition skills in non-human animals is made difficult by our limited ability to communicate with animals about abstract information or concepts. But in past work, metacognition in primates had been successfully probed by employing an ingenious technique: Animals were familiarized with a test t...
