How HIV 'exhausts' killer T cells

...not exist, he said. The researchers are also exploring PD-1 measurement as a diagnostic tool, said Walker. "Currently, we just count the number of helper T cells to decide when to treat someone, but we are excited about the possibility that adding PD-1 measurement might tell us more about the likelihood ...

Virtual realities against pain

...between taking a flight, driving, downhill skiing, exploring buildings and many more activities. In this study, peer-reviewed publications on ADTs and pain have been reviewed to determine the clinical effectiveness and importance of using these techniques as analgesic. The results suggest that the ADTs can ...

DOE JGI finishes 100th microbial genome

...s opened a particularly productive vein to mine in exploring and expanding the frontier of microbiology. Especially where, through conventional culture methods, we are unable to shed light on the metabolic profiles of these microorganisms and their environmental implications, DNA sequencing provides us a welco...

Progress being made in exploring potential use of stem cells to treat heart disease

Scientists are making headway in exploring the potential future use of stem cells to treat heart disease, according to a review article in the current issue of Nature (June 29, 2006). Authored by Gladstone Institute of Cardiovascular Disease Director Deepak Srivastava, MD, and Gladstone Ins...

Epidemic of unneeded amputations

...s often jump too quickly to amputation rather than exploring medical advances that can prevent limb loss," said Dr. Craig Walker, of the Cardiovascular Institute of the South, in Houma, La. Walker is a pioneer in a medical procedure to combat these trends: Cool Laser Revascularization for Peripheral Artery Th...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

... Maine proper, seaward of Georges Bank, scientists exploring a chain of extinct, undersea volcanoes known as the New England Seamounts are finding both species that are likely new to science and species whose existence has been known on the eastern side of the Atlantic but never before seen in the Gulf of Main...

How sperm crack the whip

... do." Further studies, said Clapham, will aim at exploring the many controlling currents inside sperm and also tracing how calcium triggers hyperactivation once it enters the cell. Such studies will enable exploration of sperm machinery from tail to head ?analyzing processes ranging from tail motility to the...

Wrinkled membranes create novel drug-delivery system

...ic cooling. Chaieb and colleagues at Illinois are exploring ways to coat the capsules with the nanoparticles. When exposed to a magnetic field, the nanoparticles would cool down and remove heat from the capsules. The capsules would then wrinkle and release the drug. ...

Oceans are 70 percent shark free

...e 10-year Census of Marine Life programme which is exploring the abundance, distribution and diversity of life in the world's oceans. The team also used findings built up over the last two decades when the University of Aberdeen's Oceanlab started developing landers - remotely operated vehicles - which have ...

UW scientists unravel critical genetic puzzle for flu virus replication

...m to interact." What's more, scientists have been exploring the possibility of using strains of influenza to ferry genes from one virus to another to speed and optimize vaccine production. More efficient methods of vaccine production will be critical should a global outbreak such as the "Spanish " flu pandemi...

Poison + water = hydrogen. New microbial genome shows how

...continued value of microbial genome sequencing for exploring the useful capabilities of the vast realm of microbial life on Earth," says Ari Patrinos, director of the Office of Biological and Environmental Research, part of the U.S. Department of Energy's (DOE) Office of Science. DOE, which funded the study, i...

Scientist measures role of science's coolest player: The snow

... forthcoming simulations, Vavrus plans to continue exploring the effects of both nearby and faraway snow cover on local climate conditions. ...

The secret love life of plants

...cell instead of two. The researchers have now been exploring the question if whether, under these conditions, fertilisation is possible at all. It turned out that the mutated pollen can survive and even grow into a female partner. Once it has arrived there, the single sperm cell of the cdc2 pollen merges only ...

New research examines genetics of successful aging

...d alcohol consumption, with the goal of eventually exploring the interactive effects of genes and lifestyle on successful aging. As expected, the study identified an increased frequency of the APOE E2 allele and a decreased frequency of the APOE E4 allele among the elders compared to the group of young adul...

The brain is broadly wired for reproduction

...though the findings are considered a first step in exploring the GnRH reproduction-related circuitry in the brain, Buck acknowledges that they have already learned a great deal just by defining the circuits. "These findings now set the stage for studies in which the neurons in those circuits can be analyzed to...

Harnessing genomic research

...ege London and the Gurdon Institute, Cambridge are exploring ways to identify molecular signatures resulting from the loss of specific gene function in breast cancers that will correlate with susceptibility to a new anti-cancer drug being developed by KuDOS. The drug involved has the potential to kill tumour c...

Scientist uses form to explain function of key building blocks of life

...understand what research is and what's involved in exploring something that hasn't been observed before," he says. ...

Key brain regulatory gene shows evolution in humans

...e is likely only the beginning of a new pathway of exploring how the pressure of natural selection influenced evolution of other genes. They also said their finding demonstrates how evolution can act more efficiently to alter the regulatory segments, or "promoters," that determine genes' activity, rather than...

A New Era of Hope for the World's Most Neglected Diseases

...inical research on neglected diseases, and PLoS is exploring the feasibility of launching a new journal devoted specifically to these diseases. The ?005 reality?is that there is an unprecedented window of opportunity for neglected-disease control, and PLoS will play its part. ...

Deep treasure to be found in Oculina Bank

...ent activities in the area. The group will also be exploring new portions of the reef revealed by a recently developed high-resolution seafloor map. The Oculina reefs, in depths from 250 to 300 feet, were built over the past thousand years or so by the delicate ivory tree coral Oculina varicosa, and include a...
