Study suggests some drug resistance to influenza B medications

...rkville, South Victoria, Australia, comment on the findings concerning possible drug resistance to influenza B medications. “The report by Hatakeyama et al raises more questions than it answers, including questions about viral evolution, biological fitness, and transmissibility. But some facts are strikin...

Mechanism of nicotine's learning effects explored

.... Huibert Mansvelder and colleagues reported their findings in the April 5, 2007, issue of the journal Neuron, 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 wi...

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

...correspond to known promoters and enhancers. These findings enabled us to generate computational algorithms that identified hundreds of novel genomic regions with regulatory potential." Moreover, says Heintzman, this 'histone code' was able to accurately distinguish between promoters, from which gene transcri...

Glucose triggers brain cell death in rats after hypoglycemic coma

...is not legitimate to immediately extrapolate these findings to humans. Second, there are many ways to go wrong in humans by not treating hypoglycemia aggressively enough. The results of this one paper do not mean that clinicians should take an overly cautious approach to hypoglycemic coma." In his own curr...

Study shows isolation of stem cells may lead to a treatment for hearing loss

...ty School of Medicine, recently published research findings in Developmental Neuroscience which suggest new ways of treating hearing loss. These researchers have isolated “cochlear stem cells?located in the inner ear and already primed for development into ear-related tissue due to their proximity to the ear...

Changes in amino acids in the 1918 influenza virus cut transmission

...ore important for optimal viral transmission. "Our findings indicate that, to become more transmissible in humans, the currently circulating avian influenza H5N1 virus requires a receptor binding change in the hemagglutinin to a predominant alpha-2,6 sialic acid binding preference," Dr. García-Sastre adds. "A...

Despite their heft, many dinosaurs had surprisingly tiny genomes

...ott V. Edwards, both at Harvard. They report their findings this week in the journal Nature. "We see distinct differences between two major lineages of dinosaurs," says Organ, a postdoctoral fellow in organismic and evolutionary biology supported by the National Institutes of Health. "The theropods -- carn...

Study finds antibiotic resistance in poultry even when antibiotics were not used

...e complicated than once thought," Lee said. "These findings suggest that banning antibiotics at the farm level may not be as effective as assumed. We need further studies to identify which management practice would be effective" Lee stresses that for consumers, the advice on poultry is the same that it's a...

Scientists find genes involved in the battle between Hessian flies and wheat

Shulman, a Howard Hughes Medical Institute investigator at Yale University School of Medicine. Earlier studies have shown that, in comparison to 20-year-old adults, even lean and healt...

New compound prevents alcoholic behavior, relapse in animals by blocking stress response

...he dark side of addiction is treated." The new findings build on previous work showing the effectiveness of blocking certain CRF receptors—proteins that bind CRF and make it active—in treating alcohol dependence in animals. CRF levels in the brain rise in the short term after drinking; in subjects that ar...
