Were the first macromolecules created on a primitive beach? view more (2002-06-19)
Research offers new approach to developing treatments for cocaine and amphetamine addiction
The study shows that highly addictive drugs, like cocaine and amphetamine, require a neurotransmitter called CART (Cocaine- and Amphetamine-Regulated Transcript) peptides to produce their maximal effects. view more (2005-09-29)
Role of anesthetics in Alzheimer's disease: Molecular details revealed
Inhaled anesthetics commonly used in surgery are more likely to cause the aggregation of Alzheimer's disease-related plaques in the brain than intravenous anesthetics. view more (2007-01-29)
Scientists Develop Method for Comprehensive Proteome Analysis
Investigators at Burnham Institute for Medical Research (Burnham) have deciphered a large percentage of the total protein complement (proteome) in Schizosaccharomyces pombe (S. pombe) fission yeast. view more (2009-04-09)
What change does prokineticin 2/Bv8 have in human hepatocellular carcinoma?
Liver hepatocarcinoma is a highly vascularized cancer, and more and more research is focused on the molecules controlling angiogenesis. view more (2008-03-18)
Salutary Properties Of Thick Broth
L.A. Lyapina and her colleagues from the Department of Human and Animal Physiology of the Moscow State University have revealed that collagen products rich in proline are necessary for a successful performance of many vital processes in the body. The most common protein of vertebrate animals is collagen; collagenous fibres are found in skin,... view more... (2003-02-20)
Head and neck cancer vaccine targets proteins to create immune response
Most attempts to create therapeutic cancer vaccines are based on custom-made approaches that use a patient's own tumor cells to generate a strong immune response against cancer. However, developing these kinds of personalized vaccines is time-consuming, expensive and often impractical. view more (2007-04-18)
Tarantula venom and chili peppers target same pain sensor
Venom from a West Indian tarantula has been shown to cause pain by exciting the same nerve cells in mice that sense high temperatures and the hot, spicy ingredient in chili peppers. view more (2006-11-09)
Bug surprise for drug traffickers - Microbiology Today: May 2004 issue
Bacteria could be the new weapon in the fight against drug trafficking, according to an article published in the May 2004 issue of Microbiology Today, the quarterly magazine for the Society for General Microbiology. Researchers at CNAP, University of York, have found bacteria that grow on heroin and morphine and believe that two special proteins... view more... (2004-05-17)
Discovery can make it possible to take more drugs orally
Many drugs cannot be administered orally since they cannot be taken up by the intestines. All attempts to solve this problem have thus far resulted in unacceptable risks of side-effects, mainly because the intestinal wall is so severely impacted that not only the drug but other substances, including toxins, can be absorbed. Now a team of... view more... (2003-12-01)
Yin and yang -- Balance could play key role in progression of Alzheimer's disease
Researchers at Rensselaer Polytechnic Institute are challenging current thinking on the causes and prevention of Alzheimer's disease, offering a new hypothesis that could be the key to preventing this form of dementia. view more (2007-05-30)
Alzheimer's research yields potential drug target
Scientists at UC Santa Barbara and several other institutions have found laboratory evidence that a cluster of peptides may be the toxic agent in Alzheimer's disease. Scientists say the discovery may lead to new drugs for the disease. view more (2009-07-02)
Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned
Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed. view more (2007-08-17)
Calorie restriction may prevent Alzheimer's through promotion of longevity program in the brain
A recent study directed by Mount Sinai School of Medicine suggests that experimental dietary regimens might calm or even reverse symptoms of Alzheimer's Disease (AD). view more (2006-06-15)
MIT material stops bleeding in seconds
MIT and Hong Kong University researchers have shown that some simple biodegradable liquids can stop bleeding in wounded rodents within seconds, a development that could significantly impact medicine. view more (2006-10-10)
UCLA AIDS Institute researchers find a peptide that encourages HIV infection
UCLA AIDS Institute researchers have discovered that when a crucial portion of a peptide structure in monkeys that defends against viruses, bacteria and other foreign invaders is reversed, the peptide actually encourages infection with HIV. view more (2007-05-11)
Antibacterial detergents don't create superbugs - Microbiology Today: May 2004 issue
Research proves that use of antibacterial detergents in the home and in hospitals can reduce the development of superbugs, according to an article published in the May 2004 issue of Microbiology Today, the quarterly magazine for the Society for General Microbiology. Using antibacterial products, including disinfectants and antiseptics, has been... view more... (2004-05-17)
University of Ulster spearheads giant leap forward in medicine
Researchers at the University of Ulster have uncovered a vital weapon in the fight against killer conditions like cancer and heart disease - frog venom. The team, headed by Professor Chris Shaw, has discovered that molecules called peptides, secreted by rain forest frogs to ward off predators, have the potential to: * Dramatically... view more...

Exploiting Nature's Weapons in the Fight Against Diabetes
Scientists at the University of Ulster are harnessing molecules produced naturally in the body to tackle one of the world's major health problems - diabetes. Their novel approach involves bioengineering gut peptides - molecules produced in the human intestine and released in response to feeding - to prolong their duration of action and,... view more...
