New Imaging Technique Pinpoints Dead Heart Muscle

...scle damage from a heart attack. The test pinpoints in injured heart tissue depleted concentrations ofcreatine, a molecule that provides energy to the muscle. The new test worksusing commonly available magnetic resonance imaging scanners, which will makethe technique potentially widely available. ...

A picture and 2,000 words in Science magazine: two Kansas scientists work at forefront of emerging technology

... a long-time goal ofscientists, and the microscope pinpoints the target of only a few microns. Byanalyzing a sample in a grid pattern, a map of localized chemistry of themolecules is developed that can be superimposed over the visible physicalmicrostructure under study. "We were invited by the Science editors ...

Genes may help protect kidneys from diabetes damage

...t the Endocrine Society annual meeting in Toronto, pinpoints three genes that may play a role in diabetic kidney disease, which affects between 1.5 and 3 million Americans. To understand the roots of this common complication, scientists examined gene function in healthy and sick mice. Earlier studies at Ohio U...

Researchers discover major diabetes susceptibility gene

...ed in the October 2000 issue of Nature Genetics , pinpoints a new and unexpected biochemical pathway leading to diabetes and suggests novel approaches to prevention, diagnosis and treatment. Identifying this new diabetes gene is also a major coup for genetics. This is the first time that a genome-wide app...

Climate change puts food production at risk

...enarios for all countries of the world. The report pinpoints the hot spots where productivity is most likely to be affected by projected climate change. Not surprisingly, the world's 40 poorest nations, with a third of the current global population and over a half of the undernourished people in the world, are...

New study puts dinosaur noses in their place

...dinosaurs' nostrils? But according to a study that pinpoints a new position for the nostrils, the answer could help explain how the creatures found food, detected predators, reproduced and regulated brain and body temperature. The study, reported in the Aug. 3 issue of the journal Science, will give many din...

Still waters? 'Clear-cutting' robs the deep-sea of ancient treasures

...bruary issue of the AAAS journal, Science, Roberts pinpoints 18 critical places world-wide where conservation resources would likely do the most good. Topping the list of 18 are 10 conservation "hotspots"-from the Philippines and the Gulf of Guinea to the Sunda and Mascarene Islands, and Eastern South Africa. ...

New cholesterol disorder discovered As predicted from gene's role

Amazonian devastation: Common sense quantified to predict disaster

...ct and the Smithsonian Tropical Research Institute pinpoints specific causes of forest destruction in hopes of stemming the tide. Human population density, distance to the nearest highway and dry season severity best predict the extent of deforestation, the group reports in a Journal of Biogeography article re...

Scientists map signaling molecule crucial to survival, disease

...t ordinarily would not recognize, and in doing so, pinpoints the original location of the phosphate group. The Shokat lab carried out the chemical sleight of hand, while a collaborator, Bradford Gibson, PhD, and his colleagues performed all the mass spectrometry analysis. Gibson is a researcher at the Buck...

Scientists identify molecular step that causes intoxication

...f the intoxicating effects of alcohol. The finding pinpoints perhaps the best target yet for a drug to block alcohol's effect and potentially treat alcoholism, the scientists say. The mechanisms by which alcohol acts on the brain are thought to be similar throughout the animal kingdom, since species from wor...

Shyness can be deadly

... Greater Los Angeles Healthcare System. "Our study pinpoints the biological mechanism that connects personality and disease."

New proteomics core at OHSU will speed discovery process

...ttended with the help of a robotic arm that slowly pinpoints protein samples in gels visualized with fluorescent stains to enhance their identity, cuts the samples from the gels, and breaks them down with enzymes, preparing them for closer examination with the mass spectrometer. It can process up to 192 sample...

NASA scientists get global fix on food, wood & fiber use

...nsumption varies greatly by region, and this study pinpoints areas where human populations require imported basic food, fiber and fuel. Regions with greater demands than available plant-derived resources may be more vulnerable to climate change and other socio-economic impacts. Imports may put greater pressure...

Anti-cancer compound in vegetables found to block late-stage breast-cancer cell growth

...ch extends the 1992 discovery at Johns Hopkins and pinpoints how SUL works during later stages of cancer, such that SUL can suppress the orderly division process in human breast cancer cells. "The findings may be helpful in the development of new breast cancer prevention and treatment strategies," Singletary s...

New way to protect brain from stroke damage

...ave been disappointing," they wrote. The new study pinpoints a new target underlying toxic levels of calcium in the brain, disclosing a potential new therapeutic target for stroke, the researchers added. Blockers of ASIC1a, either alone or in concert with other neuroprotective methods, might therefore prove us...
