Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...n the use of reverse genetics techniques to combat emerging bird flu pandemic threats. To that end, researchers intend to: Characterize the function of the influenza viruses using a structure-based approach; Develop simulations of the molecular dynamics involving interactions among major factors that ...

Stem cell identity in culture may strongly depend on the cellular microenvironment

... These observations are in line with the currently emerging view that differentiation is context dependent rather than a pre-programmed attribute of the cells. In practice, this work provide a rationale to research strategies that aim to increase the efficiency of stem cell-related culture methods and, perhap...

Bird flu -- Call for antiviral drugs to be shared

...iviral drugs might be the best way to deal with an emerging pandemic. 'Bird flu'(avian H5N1 influenza) has no...ion on air travel to model the global spread of an emerging influenza pandemic and its containment. They conclude that much will depend on the 'reproductive num...

New science of metagenomics 'will transform modern microbiology'

The emerging field of metagenomics, where the DNA of entire communities of microbes is studied simultaneously, presents the greatest opportunity -- perhaps since the invention of the microscope -- to revolutionize understanding of the microbial world, says a new ...

Temple University Hospital investigates treatment for cervical dysplasia

...HPV, and those who will become infected, there are emerging non-surgical options in development." HPV vaccines are expected to be a significant advance in women's healthcare, but they will not protect all women from cervical cancer. "Prophylactic vaccines will probably not help the more than 350,000 women...

ASU researchers test antibacterial effects of healing clays

...n Africa. Buruli ulcer has been declared to be "an emerging public health threat" by the World Health Organization (WHO). Related to leprosy and tuberculosis, the Mycobacterium ulcerans produces a toxin, lesions, and destroys the fatty tissues under the skin. "The toxin is immunosuppressant; the patients f...

Researchers seek to design first treatment for neuroAIDS

...immune cells that causes disease in the brain. The emerging answer is that the indirect effects of infection, like proteins released by the virus and chemicals released by human cells reacting to them, are toxic in themselves. As a result, labs nationwide are urgently searching for compounds that counter suc...

The subtleties of tropical forest demise

... forests are disappearing, but many of the new and emerging threats are virtually invisible, unless you're on ...he ground." The editors define four categories of emerging threats to tropical forests: (1) Those that have only recently appeared, such as the virulent chytri...

'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens

...emiology. He added, "To address the challenges of emerging infectious diseases and biodefense, public health practitioner and diagnosticians need a comprehensive set of tools for pathogen surveillance and detection." GreeneChip features include a comprehensive microbial sequence database that integrates p...

Lab-on-a-chip could speed up treatment of drug-resistant pneumonia

...o get a resistant strain," Lochhead said. "It's an emerging public-health disaster." The most acute cases are admitted into intensive care units, where doctors have just days, if not hours, to save the patients' lives, Lochhead said. But reliably identifying the bacterial strain that's causing the infectio...

T for two: Scientists show how immune system chooses best way to fight infection

...ys Professor Hayday. "This means that most T cells emerging at that time will be regulatory. Regulatory T cells prevent an over-active immune system from causing inflammatory damage to the body. This may be one of the key steps in preventing the mother from rejecting the foetus growing inside her." ...

Some butterflies travel farther, reproduce faster

...hey developed mature eggs sooner (three days after emerging from the pupa) which could enable them to mate and...butterflies live between two and three weeks after emerging from the pupa, so they have to produce eggs quickly. In the fragile world of a butterfly, a day can ...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...akthroughs for health in developing countries seen emerging from the new world of regenerative medicine, according to a study published today in the prestigious journal Public Library of Science (PLoS) Medicine. Conducted by University of Toronto researchers (from the McLaughlin Centre for Molecular Medicine...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...latter is clearly too long, especially in light of emerging threats such as H5N1 avian influenza. "For some respiratory viruses, you've either cleared the infection at that point or succumbed to the infection," Tripp said. "What we've developed is the next generation of diagnostic testing." ...

New dyslexia theory blames 'noise'

...throw it off, according to a new model of dyslexia emerging from a group of recent studies. The studies contradict an influential, 30-year-old theory that blamed dyslexia on a neural deficit in processing the fast sounds of language. Instead, the studies suggest that children with dyslexia have bad filter...

Does natural selection drive the evolution of cancer?

...and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology. Insights from their work may have profound implications for understanding why current cancer therapies often fail and how radical...

Researchers discover key mechanism by which lethal viruses Ebola and Marburg cause disease

World-wide warning of highly drug-resistant tuberculosis

...ew forms of highly drug-resistant tuberculosis are emerging and action must be taken soon before they become widespread globally, says an editorial in this week's BMJ. The authors say that urgent action is needed to implement effective tuberculosis control strategies, especially in countries where tuberculo...

Dr. James Castracane, the project's co-investigator, who is head of the Nanobiosciences Constellation at CNSE, said, "By integrating cutting-edge science and engineering at the nanoscale level with vital biomedical research, i...

Extraordinary life found around deep-sea gas seeps

...d, the scientists observed 30?0 cm long tube worms emerging from beneath limestone boulders and slabs lying at the core of the seeps. Around the rocks were patches of blackened sediment and pockets of white bacterial mats. Most sites also had extensive shell beds consisting of live and dead shells of various...
