MCG Medical Center has joined a study taking place in intensive care units across the country to evaluate the efficacy of the renal assist device, says Dr. Harold M. Szerlip, MCG nephrologist special...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...Earth's crust because the strategies by which they survive may be similar to the earliest strategies of life on Earth, and perhaps also on other planetary bodies," said Rachel M. Haymon, UCSB professor of geology. Newly discovered geological and biological manifestations of hydrothermal activity at two site...

Transplantation Of Monkey Embryonic Stem Cells Reverses Parkinson Disease In Primates

... well below theestimated number of DA neurons that survive after fetal celltransplants (approximately 10%). While this may be a differenceobserved between transplantation in monkeys and humans, Langstonstresses that it may be necessary for far more DA neurons to surviveand for that survival to be long lastin...

Researchers reveal the infectious impact of salmon farms on wild salmon

... literally eating the fish alive. Adult salmon can survive sea lice infection, but young salmon are much more vulnerable due to their small size. Under natural conditions, juvenile pinks and chum do not typically have to contend with sea lice because the adult salmon are far out at sea and are widely disper...

Solution to Pollution: New Bacteria Eats Toxic Waste

...that allows these bacteria to degrade the PAHs and survive in the soil. Such knowledge may help researchers b...o fully understand how these microbes function and survive in the environment so contaminated sites around the world can reap the benefits. Collaborations are ...

Researchers discover molecule that causes secondary stroke

... hemorrhagic stroke. Sixty percent of patients who survive the initial stroke develop vasospasm, and 40 percent of them die from it. Vasospasm, says neurology department researcher Joseph Clark, PhD, results from a buildup of toxins caused by bleeding from the initial stroke. "Normally the cerebral spinal f...

Highly adaptable genome in gut bacterium key to intestinal health

...mechanism not only allows the bacterial species to survive rapidly changing nutrient conditions but also helps maintain the functions and stability of the gut's highly complex microbial society, according to researchers at Washington University School of Medicine in St. Louis. Their findings are reported in...

New SARS Protein Linked To Important Cell Doorway

...s and how important it is to the virus' ability to survive and reproduce. "If knocking out orf7a significantly attenuates the virus, we may able to look at the possibility of using it to make a SARS vaccine," Pekosz speculates.

The very unexpected life and death of a leukemic cell

...disease in which cells in the bone marrow grow and survive to the point where they become abnormal and malignant (leukemic). The progression of the disease is slow and there has been a lack of information regarding the rate of production of CLL cells, and the time-course of their death. For years, doctors a...

The Bacteria's guide to survival

...nd that cells infected with the bacteria tended to survive treatment with staurosporine, a chemical that normally induces apoptosis. Overall, the group's findings support previous speculations that some bacteria influence gene expression and the fate of cells in their hosts by tugging on the host cells' mem...

Family trees of ancient bacteria reveal evolutionary moves

... life span, Cyanobacteria have evolved a system to survive a gradually increasing oxidizing environment, making them of interest to a broad range of researchers. Blank is able to draw her hypothesis from family trees she is drawing of Cyanobacteria. Her observations are likely to incite debate among biologi...

Surprising findings reported about iron overload

...0 years ago, and the mutation may have helped them survive iron-poor diets." Hemochromatosis or iron overload occur in 0.3-0.5 percent of white persons of northern, central, and western European descent. In fact, a health-screening program conducted by Barton and Acton at an Alabama forest products mill det...

...cid, or PGA--must be present for S. epidermidis to survive on medical implants. S. epidermidis infections are rarely fatal but can lead to serious conditions such as sepsis (widespread toxic infection) and endocarditis (inflammation of the lining of the heart and its valves). Because of the ability of PGA t...

Viral protein influences key cell-signaling pathway

... that "remember" a vaccination or an infection can survive for years or even decades. "The p300 protein is an important central regulator of gene activity in lymphocytes and many other kinds of cells," says Michael Lairmore, professor and chair of veterinary biosciences and a member of the OSU Comprehensive...

...aestivation. During this time they do not feed and survive on fat reserves. The frogs return to the surface after heavy rain, sometimes for as little as a week - to find food and build up fat reserves.

Biodiversity hotspots identify conservation priorities

...t's most threatened mammals, birds, and amphibians survive within habitat covering just 2.3 percent of the Earth's surface (roughly equivalent to the combined areas of the five largest U.S. states). This habitat originally covered 15.7 percent of the Earth's surface, an area equivalent in size to Russia and ...

Low level of extinction during ice age linked to adaptability

... answer: because those aquatic life forms that did survive during this era were singularly equipped to endure severe fluctuations in temperature and sea levels. Those that were not died in a mass extinction that heralded the ice age's onset. "These results not only clue us in to what happened many millions ...

Gray wolves maintain the food chain in winter

...could determine whether scavengers will be able to survive and reproduce. It seems clear that wolves have the potential to provide a safety net for scavengers, extending the time they need to adapt to a changing environment. Thanks to a rebounding wolf population, field researchers can measure the magnitude...
