Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...insulin in response to blood glucose. "The bottom line is that if you don't have delivery of enough nutrients from the mother to the baby, the baby's pancreatic cells will be programmed abnormally," said principal investigator Mary-Elizabeth Patti, M.D., Assistant Investigator in Joslin's Research Sectio...

Timing is everything: First step in protein building revealed

...protein-building machinery recognizes the starting line for a gene'sinstructions, it first alters its structure and then releases a factorknown as eIF1, a step necessary to let it continue reading the assemblyinstructions. Even though yeast are the most primitive relatives ofhumans, the protein-building m...

Research on Worms Yields Clues on Aging

... longevity," Kornfeld says. "We're continuing this line ofresearch to identify the precise functions of the nervous system thatcause the worms to live longer."Because the researchers found that anticonvulsants affect the nervoussystem of C. elegans, they also plan to use the worms as modelorganisms to inv...

Researchers reveal the infectious impact of salmon farms on wild salmon

...ng in wild salmon habits. "There's a double bottom line here. The full ecological costs of industrial scale salmon farming must be quantified as well as the economic ones," says Volpe. "For the migratory runs we studied, there may be very little time left." ...

New Clues Add 40,000 Years to Age of Human Species

...ypothesis that suggests we all trace to an ancient line that first evolved in Africa and then displaced other hominids as recently as 50,000 years ago. Ian McDougall of Australian National University (ANU), Frank Brown of the University of Utah and John Fleagle of Stony Brook University, report their fin...

Nanogen Issued Patent for Electronic Microarray With Memory

...ilable in 2005. Nanogen's subsidiary SynX offers a line of point-of-care diagnostic tests and is building expertise in cardiac related health conditions. Nanogen's ten years of pioneering research involving nanotechnology may also have future applications in medical diagnostics, biowarfare and other indus...

NYC's First Rapid HIV Drug-resistant AIDS Case Prompts Call to Step Up HIV Prevention

...s and providers can usually find a second or third line drug therapy regimen for effective treatment. This man's strain of infection appears to be much more pathogenic, much more able to wreak havoc with his immune system, and medical providers and public health officials are being well-advised to work cl...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...itt said the discovery has opened an important new line of thinking. The other researchers involved with this study were Jennifer Victor, a former Purdue graduate student now at Butler University; and Jessica Young, a botany and plant pathology laboratory technician. Lolle, a Purdue research scientist, i...

Scientists identify new model Of NK cell development

...nts of the body's immune system that are the first line of defense against cancer and infectious diseases. Scientists have believed for years that human NK cells are generated in bone marrow, but Michael Caligiuri, director of the OSU Comprehensive Cancer Center and the senior author of the study, says r...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

...natively, we can develop ways to induce that first line of polyspecific antibody defense during vaccination, if these antibodies are not harmful to those being vaccinated," Haynes said. "We now have a window into how to study HIV vaccines from the host side of the problem," he said. Collaborators on the...

Wisconsin researchers identify sleep gene

Put through a series of tests, the short-sleeping flies, named minisleep (mns), were found to perform normally and did not appear to be impaired by sleep deprivation. The mns flies, however, di...

The nitric oxide produced in this layer of cells diffuses back into the blood vessel walls, where it relaxes surrounding muscle cells and increases blood flow. It also diffuses into the lumen of the ...

Low level of extinction during ice age linked to adaptability

Powell tackled the question of why extinction rates were so low during that great ice age by closely examining geographic patterns of evolution and extinctio...
