Survey reveals women and doctors aren't talking about HPV

...been exposed to the virus. However, screening will still be necessary, since the vaccines now being researched only target some of the several types of HPV that may trigger cervical cancer.

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

...0,000 in June 2004 to 700,000 in December 2004, it still amounts to only 4 percent of infected people in India, 5 percent in Ethiopia, and 7 percent in South Africa," he writes. Internationally, Zenilman has led clinical studies to determine how best to prevent the spread of sexually transmitted diseases ...

The first impact factor for PLoS Biology ?13.9

...p has been taken toward these goals. But there is still a long way to go before the mission of the Public Library of Science ?to make the world's treasury of scientific and medical literature a public resource ?is fulfilled. We hope that PLoS Biology's first impact factor will inspire even greater support...

Scientists discover odd-ball rodent

...usual species. "Skeptics might say that if we are still discovering such amazing new animals, why are people worried about wildlife loss; but of course it is an indication of how little we know, and a window onto what we could be losing without ever knowing," said Dr. Timmins. ...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...vestigations revealed that the altered p53 protein still binds to Mdm2, one of the negative regulators of p53 that facilitate its degradation. When p53 is activated by DNA damage the same sites that are modified when the protein is slated for degradation, a different kind of chemical modification, so-call...

Map of life on Earth could be used on Mars

...understand in terms of bacterial evolution that is still not quite clear, " Blank said. "What we're trying to resolve is the evolutionary history of the core of the bacterial cell. The core is that which is not undergoing this lateral gene transfer, or does it extremely rarely." Jumping genes Jumping gen...

Stem cell treatment improves mobility after spinal cord injury

...ust suffered spinal cord injury, although there is still much work to do before we can engage in human clinical tests." Acute spinal cord damage occurs during the first few weeks of the injury. In turn, the chronic period begins after a few months. It is anticipated that the stem cell treatment in humans ...

Random gene expression may drive HIV into hiding

...atency or viral production. This intriguing notion still needs to be tested experimentally, and more broadly, much work remains to be done to understand the functional role that gene expression noise potentially plays in the progression of disease." ...

Scientists discover global pattern of big fish diversity in open oceans

...e key pieces of the global biodiversity puzzle are still out there, including the physical structures upon which the big fish congregate. There are still a few remaining in formerly productive areas. If we allow these predators some reprieve, we could re...

Research on antibiotics receives historical recognition

...ics isolated in Waksman's laboratory was neomycin, still used as a topical antibacterial agent. William F. Carroll, Ph.D., president of the Society, will present a commemorative bronze plaque to Tim Casey, Ph.D., Dean of Academic and Student Programs at Cook College, Rutgers University. H. Boyd Woodruff, ...

Newest HIV drugs should be used with FUZEON(R)

... is effective in face of HIV resistance FUZEON is still the first and only anti-retroviral drug to work outside the human immune cell (CD4), blocking the HIV virus from entering. All other currently available HIV drugs fight the HIV virus once it has entered the cell. FUZEON's unique mode of action means ...

Small worm yields big clue on muscle receptor action

...e is applied. Using this preparation, Richmond was still getting muscle contraction when acetylcholine was applied to worms lacking any of five receptor subunits known to be sensitive to levamisole, a chemical that poisons nematodes. Two additional receptor subunits -- ACR-16 and ACR-8 -- identified using ...

Researchers develop promising new gene network analysis method

...teins or switching on other genes, which activates still more genes. One way to study this web of connections would be to set off the chain reaction and study it over time. To make that happen, Brown researchers came up with a clever experiment. John Sedivy, a long-time c-Myc researcher and the director o...

Where Bacteria Get Their Genes

...colleagues' work shows that bacterial lineages can still be traced by considering only the "traditional" forms of genetic inheritance. The widespread exchange of genes does not blur the line of descent because the acquired genes get lost from the genome at a later point or, if they do persist, the bacteria...

Bioinformatics reveals new gene regulation system

...re of bacterial metabolism for which the genes are still unknown," said Gelfand. Using multiple bioinformatics tools can uncover cell systems that might have escaped experimental detection, he suggested. "By comparing hundreds of genomes, you can see patterns that are not seen when looking at just a couple...

Speak up: Louder neurons form more connections

...te well. Although the poorly-firing green neurons still formed extensive branching structures, which the researchers call the neuron’s arbor, most of those branches eventually receded while neighboring neurons formed a large number of stable connections. When the fish were five days old, the green neurons...

... operation to a methane digester system. "Methane still needs to undergo combustion, which creates issues with energy efficiency," said Hamid Rismani-Yazdi, the study's lead author and a graduate student in food, agricultural and biological engineering at Ohio State. The research showed how electricity c...

Researchers find first evidence of venom system in extinct mammal

...how long you've been working on something, you can still learn a lot just by uncovering one little piece of information," Fox added. "And we're fortunate that we are able to work where we do; central Alberta is one of the richest areas of the world to uncover the types of fossils that we're interested in."...
