Pitt researcher presents findings on when to accept organ transplants

A transplant is the only option for someone with end-stage liver disease, but patients face difficult questions when choosing the best time to receive a transplant.

Biochemical marker aids prognosis in liver transplant patients

A new study on whether the model used to identify patients most in need of a liver transplant can be improved upon found that measuring serum sodium in potential transplant patients helps to better predict those with a poor prognosis.

Air pollution thickens the blood and boosts inflammation

Air pollution, and especially particulate matter, thickens the blood and boosts inflammation, finds experimental research in Occupational and Environmental Medicine.

Caution on cosmetic injections administered in non-healthcare settings

Local health departments in Northern Virginia, the District of Columbia and Maryland are investigating an outbreak of serious skin reactions among at least 16 women who have developed the condition after receiving cosmetic injections in October and November 2004.

$9.8 million grant to research cancer risks from space radiation

NASA awarded a research grant worth more than $9.8 million over five-years to the University of Texas Southwestern Medical Center in Dallas.

Separating chromosomes improves genetic test results

A new process that helps unmask genetic mutations by separating chromosomes so they can be studied individually may improve the diagnostic yield of some genetic tests, according to findings of a Colon Cancer Family Registry study published today in the Journal of the American Medical Association.

Blood tests improve within two weeks of quitting smoking

Long-term smokers who quit may benefit from almost immediate improvements in blood platelet function, which could potentially reduce their risk of heart attacks or strokes caused by blood clots, according to a new study in the Feb. 15, 2005 issue of the Journal of the American College of Cardiology.

IVF process may lack natural growth factors in fluid

The lack of natural growth factors in the fluid in which IVF embryos are grown could have lifelong effects on people conceived this way. That is the implication of a study on mice by Australian researchers, who say preliminary studies of human embryos back their claims.

Nanoscale mechanism to externally control the function and action of a protein

"We can switch a protein on and off, and while we have controlled a specific protein, we believe our approach will work with virtually any protein," said Giovanni Zocchi, assistant professor of physics at UCLA, member of the California NanoSystems Institute and leader of the research effort. "This research has the potential to start a new approach to protein engineering."

Research shows that individual NAc neurons play a role in Pavlovian learning

While the brain center called the nucleus accumbens (NAc) has been called a key component of the brain's "reward" pathways, researchers' experiments with rats have now shown that the center processes not only rewarding stimuli, but also aversive stimuli.

New detection system to test athletes for performance-enhancing drugs

Scientists at The University of Nottingham are leading the field in developing a new detection system that could be used to test athletes for performance-enhancing drugs.

Angiogenesis inhibitor molecules defend against the development and spread of cancer

Research led by investigators at Beth Israel Deaconess Medical Center (BIDMC) helps explain how a group of angiogenesis inhibitor molecules serve as an important defense mechanism against the development and spread of cancer, offering key insights into why cancerous tumors grow at different rates among different individuals.

More dependable, less expensive tool to help detect bladder cancer earlier

Researchers at The University of Texas M. D. Anderson Cancer Center found that a simple test that can be administered and read in the doctor's office was three times more effective than a conventional laboratory test for detecting bladder cancer.

Discovery may have implications for the treatment of hemophilia A and B

University of North Carolina at Chapel Hill researchers have made a discovery that may have implications for the treatment of liver-based genetic defects such as hemophilia A and B in humans.

Green tea extract has potential as an anti-cancer agent

A new study on bladder cancer cells lines shows that green tea extract has potential as an anti-cancer agent, proving for the first time that it is able to target cancer cells while leaving healthy cells alone.

Ebola virus outbreaks linked to infected wild animal carcasses

All recent Ebola virus outbreaks in humans in forests between Gabon and the Republic of Congo were the result of handling infected wild animal carcasses, according to a study by the Wildlife Conservation Society (WCS) and its regional partners

Paradox suggests reasons why COX-2 inhibitors hurt and help

Laboratory studies at Johns Hopkins have revealed that certain products of the enzymes COX-1 and COX-2 can both protect and damage the brain. The findings, published in the February 2005 issue of the Journal of Neurochemistry, offer tantalizing clues to why drugs like Vioxx and Celebrex, which block COX-2, can ease arthritis but potentially harm the heart and brain.

Key insight into the process of normal synapse development may lead to improved treatment of conditions such as drug addiction and epilepsy

Communication in the brain travels from one nerve cell to another through critical connections called synapses. These neuron-to-neuron junctions form early in brain development, and their construction was thought to be guided by the nerve cells themselves.

American Fertility Association alarmed by Judge's embryo ruling

The recent ruling in favor of a Chicago couple, who sued for wrongful death when their fertility clinic failed to preserve an embryo, raises great concerns for fertility patients across the United States.

New primate-specific gene family that spans about 10% of human chromosome 2

A team of scientists led by Peer Bork, Ph.D., Senior Bioinformatics Scientist at the European Molecular Biology Laboratory, report today in the journal Genome Research that they have identified a new primate-specific gene family that spans about 10% of human chromosome 2.
