WCS says avian flu prevention should focus on farms, markets

...g with our Mongolian and international partners to confirm and track the movements of Avian flu in the region," said Dr. Billy Karesh, head of the WCS team currently in Mongolia. "The best hope for successfully containing the spread of avian flu is focusing our limited resources on the hubs where humans, liv...

Genetics links whale to two different ocean basins

...onstrates the ability of molecular technologies to confirm the movements of an individual whale between ocean basins." The study examined DNA samples extracted from skin biopsies collected from whales in the wintering grounds of both the Indian and South Atlantic Oceans for evidence of inter-oceanic exchang...

Hospitalizations because of chicken pox down dramatically since implementation of vaccine

... Zhou et al. "?these findings do not conclusively confirm that childhood varicella vaccination is as cost-effective as originally anticipated, for several reasons. First, the cost of the vaccine has increased more than $10 per dose in inflation-adjusted terms since 1995 (the current public sector price per ...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

...er systems." The next stage is for researchers to confirm that other viruses such as HIV also have an intermediate step. Preliminary data from the Melikyan laboratory indicate that this may be the case for HIV. "We already know that the entire HIV fusion sequence is very slow, sometimes taking several hours...

Old drug, new tricks: Prospects for slashing the impact of malaria

...search (PNGIMR) and the University of Melbourne to confirm significant health benefits in the new application of an old malaria drug - at just 12 cents a dose. The project is supported by a AUD$3. 7 million grant to PNGIMR from the Bill and Melinda Gates Foundation. Fansidar is a 20-year-old malaria drug. ...

Marine bacterium suspected to play role in global carbon and nitrogen cycles

...ing the organism isolated in the lab allowed us to confirm our suspicions," said David Stahl, professor of civil and environmental engineering at the University of Washington. Stahl's lab group specializes in environmental microbiology and how microbial communities function in diverse locations including th...

Researchers create infectious hepatitis C virus in a test tube

... set of experiments, the researchers used HCVcc to confirm that a molecule called CD81, which sits on the surface of the human cell membrane, plays a crucial role in the entry of HCV. Scientists have known that a protein produced by HCV, called E2, binds to CD81, and they believed that this interaction is n...

The synapse is a shotgun

...urther studies using their simulation technique to confirm the ectopic release mechanism and explore its possible functions. "Although we are convinced that ectopic release exists, any time you question an accepted concept, there will be doubt and resistance," said Sejnowski. "So, we will continue to develo...

Compound from Chinese medicine shows promise in head and neck cancer

...h (-)-gossypol and induced cell death. To further confirm the importance of Bcl-xL in cisplatin resistance, the researchers used a technique called inhibitory RNA to shut off expression of Bcl-xL in the drug-resistant cells. These cells became sensitive to cisplatin when Bcl-xL was turned off, confirming it...

Fragment of yellow fever virus may hold key to safer vaccine

...apply to the whole flavivirus family. The results confirm and extend similar studies in mice, but the human antibody-virus binding configuration looks more complex, ter Meulen said. In theory, the crucial antibodies, which have been cloned, could be used for prophylactic protection after suspected exposure...

How monarch butterflies are wired for navigation

...own to specialize in polarized light detection. To confirm that the butterflies, indeed, required ultraviolet polarized light to navigate, the researchers tested the insects in a "flight simulator," in which they could control the light polarization and thus influence the butterflies' direction of flight. Th...

Achilles heel of the herpes virus possibly found

... Fuller will describe recent findings that further confirm B5's importance in HSV infection. The virology team reports that the B5 molecule appears to form a shape called a coiled coil. This intricately wound structure, they believe, may be similar to the structure of some fusion proteins of viruses and als...

Researchers find first evidence of venom system in extinct mammal

...ity in an extinct mammal, but he took it to Fox to confirm his notion. Fox and Scott had found individual canine fossils with similar grooves, but they didn't know which species of animal the loose fossils came from. The Bisonvaleus browni fossil was the first time they had seen teeth like this preserved wi...

Morphine for Chest Pain Increases Death Risk

...esearchers call for a randomized clinical trial to confirm their analysis. Meanwhile, they advise cardiologists to begin treatment with sufficient doses of nitroglycerin to relieve pain before resorting to morphine. In their analysis of the clinical data and outcomes of more than 57,000 high-risk heart atta...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...odil Bluhm of the UAF. "It now appears possible to confirm that the rich biodiversity surprising deep-sea explorers worldwide exists as well in deep Arctic waters, the most under-studied area of the ocean world." Baseline data about such long-inaccessible marine species will have growing importance for meas...

Leprosy genome tells story of human migrations, French researchers report in Science

...ording to Cole. More research will be necessary to confirm this, but the new findings indicate that the disease actually originated in East Africa or perhaps the Near East, then migrated eastward and westward. Europeans and North Africans then spread Leprosy to West Africa, and the slave trade brought the d...

Ebola virus: from wildlife to dogs

...ithout showing visible clinical signs. In order to confirm that these dogs had indeed come into contact with the virus, the scientists looked for the presence of specific Ebola virus antibodies in their blood (3). The percentage of dogs carrying such antibodies increases linearly and significantly the closer...

15-year hunt finds cause of pseudothalidomide syndrome

... wouldn't have been able to identify this gene and confirm its role in Roberts syndrome." The physical similarities of people with Roberts syndrome and those whose mothers took thalidomide suggest similar underlying biology, Jabs notes. Although there's some evidence that thalidomide prevents blood vessel g...

Discovery clarifies role of peptide in biological clock

...lls, and one of the things we'll try to do next is confirm this. We will also try to understand better how VIP synchronizes pacemakers," he said. It is surprising that the process is regulated by a peptide, usually a slow signaling agent, rather than a neurotransmitter, associated with fast events, Herzog s...

Conserved amino acids play both structural and mechanistic roles in sandwich-like protein

...amily, but testing on other specific proteins must confirm that. "Better understanding of protein folding is crucial for curing human diseases directly related to misfolding of proteins, and it is also important for the design and improvement of therapeutic enzymes," Wittung-Stafshede said. ...
