To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...d the isolated confines of a hospital and into the general population. If one could design drugs to halt the enzymes that make mutations in bacteria, this could be a way of combating the evolution of antibiotic resistance. The Dramatic Effect of LexA Inhibition Halting evolution is exactly what Romesberg ...

UCLA study assesses cost-effectiveness of Hepatitis B drugs

...ss with other treatments." Spiegel notes that the general cost-effectiveness standard accepted by society and many insurers for treating a chronic condition like hepatitis B is roughly $50,000 or less per quality-adjusted life-year gained, which is a standard measure used in assessing the outcome of health ...

Young Blood Revives Aging Muscles, Stanford Researchers Find

...ided less frequently. Rando said that it may be a general phenomenon that a person's inability to repair tissues with age-whether it's muscle, liver, skin or brain-is a matter of the regenerative cell's environment rather than the cells themselves. Rando said that finding the youth-promoting factors in the...

Natural Killers Could Lead to New Hepatitis Treatments

...ical the researchers used in their experiment is a general immune activator and does not reflect what occurs during an actual infection, he noted. Such knowledge would offer important insights into the mechanism of inflammation and liver damage due to infections, he said. ...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

...use to get rid of pests. The book is written for a general audience. "Many basic biological concepts such as evolution and genetics can be learned through pests," Waldbauer said. For example, he described recent evidence of how a new species of fruit fly is evolving based on how its diet differentiates it f...

New book explains antibiotic resistance for a broad audience

Revenge of the Microbes provides the scientific information readers will need to form opinions and make informed decisions regarding the use of antibiotics. The authors have carefully sifted through ...

Newer imaging techniques may lead to over-treatment

...ng oral anticoagulant therapy when compared to the general population," Dr. Prologo said. It is imperative that "clinicians consider the risk-benefit ratio of therapy in patients with previously undetectable small clots in the peripheral pulmonary vasculature," he added. Dr. Prologo recommends a large-scale...

NYU, Rockefeller researchers find complexity of regulation by microRNA genes

Rajewsky's research program on bioinformatics predictions of regulatory elements i...

Aircraft Cabin Ventilation Influences The Transmission Of Diseases In-flight

... industry and medical community should educate the general public on health issues related to air travel and infection. They write that good hand hygiene has been proven to reduce the risk of disease transmission, and air travellers should make it part of their normal travel routine. Dr Gendreau comments: "...

The first impact factor for PLoS Biology ?13.9

...Academy of Sciences. In fact, in ISI's category of general biology journals, PLoS Biology is ranked number 1. PLoS Biology was launched in October 2003, as an open-access home to the very best in biological research. By any measure, the impact of this launch was impressive. The on-line publication of the fi...

Does vitamin C help prevent or treat the common cold? Maybe not, after all.

...cold? The authors looked at 23 studies done in the general population, using doses of up to 2g daily, and found that vitamin C did not reduce the risk. They conclude that "the lack of effect of prophylactic vitamin C supplementation on the incidence of common cold in normal populations throws doubt on the ut...

Two studies document rise of superbugs in the environment

It can cause problems ranging from skin infections to severe bloodstream infections and even death. Researchers at the Baylor College of Medicine and Texas Children's Hospital condu...

By creating molecular bridge, scientists change function of a protein

...hors conclude that their new method may provide "a general approach to engineering biomolecules and biosystems such as receptors, enzymes, antibodies, ribosymes, DNAzymes and viruses with novel functions." Zhao is a member of the Institute for Genomic Biology and the Center for Biophysics and Computational ...

Enlisting genomics to understand flu evolution

...fecting thousands. "The key thing here is that the general notion of epidemic flu is that there's a series of successions by variants of the flu we got the previous year." But the new study shows that persistently cocirculating minor strains--which might be accumulating mutations with little obvious epidemio...

First production of human monoclonal antibodies in chicken eggs published in Nature Biotechnology

Moreover, it is the only technology to date that restricts deposition of the therapeutic protein to egg white." "Mon...

Biologists determine genetic blueprint of social amoeba

..."You can make direct analogies, or you could learn general principles about how cells regulate their behavior. Both things will apply in the studies we do." He and the other members of the international sequencing team found that there are more protein coding genes in the organism than they had thought and ...

Scalpel-free surgery could reduce risk of HIV and hepatitis exposure for health care workers

...ry. The researchers studied 709 consecutive adult general surgery operations performed between July 2003 and June 2004 in the community surgical service at The Johns Hopkins Hospital including inpatient, emergency department and outpatient surgical procedures. Data were collected on HIV, hepatitis B and hep...

Men Estimate Men's Risks Of Common Disorders Higher Than Women Do, And Vice Versa

...cintyre, from the University of Glasgow, said: "In general these lay perceptions mirror professions perceptions. However, what is unexpected is that when there was a gender difference in attribution of relative likelihood, respondents tended to perceive the risks as higher for their own sex than for the oppo...

Drawing with DNA: 'Bioart' illuminates genomics
