Researchers identify ovarian cancer biomarkers

... cancer types as a potential screening tool. A new way of detecting ovarian cancer could make a significant dent in this disease, where 70 percent of patients are diagnosed after the tumor has grown large or spread. There are few or no symptoms early in the disease and no effective screening tests. Early...

Female chimps keep the bullies at bay

Female chimpanzees may have found a fool-proof way to ensure they mate with only the highest ranking males, namely those with important social and physical characteristics that their offspring may inherit, according to a new study by Akiko Matsumoto-Oda from the Department of Welfare and Culture at O...

Brown cancer biologists identify major player in cell growth

...l cell growth," Rosmarin said. "Now that we know a way to disrupt GABP and stop division, there is the possibility that a drug can be made to do the same thing in cancer cells." ...

MIT model helps researchers 'see' brain development

...odeling the folds of the brain mathematically in a way that allows the researchers to analyze their changes over time and space. The original brain scan is then represented computationally with points. Charting each baby's brain requires about 130,000 points per hemisphere. Yu decomposed these points...

Woven scaffolds could improve cartilage repair

...ving machine. "The first joints to be treated this way would likely be hips and shoulders, though the approach should work for cartilage damage in any joint." The researchers reported the new technology in the February 2007 issue of the journal Nature Materials. The research was supported by the Natio...

LIAI completes world's most comprehensive analysis on influenza virus data

...marine fish, the ingestion of which is the primary way most people at all levels of society worldwide are exposed to this highly toxic form of mercury. Methylmercury exposure now constitutes a public health problem in most regions of the world. Methylmercury levels in fish-eating birds and mammals in...

'Marathon mice' elucidate little-known muscle type

... Oxidative metabolism is by far the most efficient way of generating energy, Spiegelman said. In the current study, the researchers produced mice with higher than normal levels of the transcriptional coactivator PGC-1â in their skeletal muscles. Transcriptional coactivators work with other cellular fa...

Mercury contamination of fish warrants worldwide public warning

...marine fish, the ingestion of which is the primary way most people at all levels of society worldwide are exposed to this highly toxic form of mercury. Methylmercury exposure now constitutes a public health problem in most regions of the world. Methylmercury levels in fish-eating birds and mammals in...

Discovery could lead to better control of hemorrhagic fever viruses

...igh lethality of New World arenaviruses, suggest a way of reducing the severity of infection, and point the way toward a sorely needed treatment strategy. The four viruses, known as the Machupo, Guanarito, Juni...

Bypassing eggs, flu vaccine grown in insect cells shows promise

... vaccine differs from approved vaccines in another way as well. The experimental vaccine focuses on a portion of the flu virus known as the hemagglutinin, which the virus uses to attach to blood cells. Unlike conventional vaccines, FluBlOk does not also include neuraminidase, an enzyme that allows a flu ...

Enhancing activity of marijuana-like chemicals in brain helps treat

...havioral Sciences. "Of course, it is a long, long way to go before this will be tested in humans, but nonetheless, we have identified a new way of potentially manipulating the circuits that are malfunctioning in this disease." Malenka and p...

NT researchers discover breakthrough in malaria treatment

...eatments, but few studies have determined the best way of treating it. In collaboration with partners at the Indonesian Ministry of Health, the MSHR team conducted a study in Papua, where they compared, head to head, two new treatments for malaria. Both contained a combination of drug based on a Chi...

How appetite-stimulating brain cells work overtime during fasting

...ely also causes changes in temperature in the same way that UCP1 does in brown fat, Diano said. "It's possible that heat may act like a neurotransmitter of a sort," Diano said. Neurotransmitters are chemical messengers that relay signals to and from neurons. "Changes in temperature could have a stron...

Prehistoric origins of stomach ulcers uncovered

...f a disease causing bacteria but also offers a new way to study the migration and diversification of early humans. The international research collaboration was led by scientists from the University of Cambridge, the Max Planck Institute in Berlin, and the Hanover Medical School. The researchers compare...

Scientists learn the origin of rogue B cells

...esearchers discovered this doesn't always work the way it was intended. "What happens is that, if the body ever produces a cell with a self-reactive antibody molecule, that cell will get arrested in development at the point where it is actually combining and creating an antibody receptor," says Rafael Ca...

Mimicking how the brain recognizes street scenes

...cally, the "layers" within the model replicate the way neurons process input and output stimuli ?according to neural recordings in physiological labs. Like the brain, the model alternates several times between computations that help build an object representation that is increasingly invariant to changes...
