A University of Central Florida researcher has demonstrated that altering AMPA receptors in animals improved their chances of surviving strokes and remaining healthier afterwards.

Results of maple syrup urine disease study published in American Journal of Transplantation
Liver transplants cured the metabolic symptoms of 11 patients with a rare but devastating genetic condition known as Maple Syrup Urine Disease (MSUD), according to a study by researchers from Children’s Hospital of Pittsburgh and the Clinic for Special Children.
All patients from the study (ranging in age from 1-20) are alive and well with normal liver function, according to
UC study is first to demonstrate that this specific receptor is working in breast cancer cells and can be “turned on” by excessive estrogen.
A hormone receptor with regulatory roles as diverse as food intake, fear response, and cardiovascular function may also be involved in breast cancer, according to UC researchers.
The UC research team, led by Hassane Amlal, PhD, and Sulaiman Sheriff, PhD, report their laboratory findings on the hormone, neuropeptide Y, and its rece
Anyone who has ever been told by their doctor to steer clear of certain foods, lower their calorie intake or cut down on salt knows just how hard it can be to avoid temptation and stay motivated. A virtual healthcare assistant is being developed to offer a guiding hand.
The personalised information system being created by the PIPS project will give users access to real-time healthcare advice anywhere at anytime over mobile and fixed-line devices, helping them to consistently make
Young adults with high levels of antibodies against the Epstein-Barr virus, the virus that most often causes mononucleosis, may be more likely to develop multiple sclerosis 15 to 20 years later, according to a study posted online today that will appear in the June 2006 print issue of Archives of Neurology, one of the JAMA/Archives journals.
Researchers have long suspected that external factors may influence the risk for multiple sclerosis (MS), a chronic autoimmune disease that aff
Over half of all plant species in Europe are at serious risk because of climate change. This is the finding of an international team of scientists working on the ALARM project led by the Centre for Environmental Research in Leipzig-Halle (UFZ). Preliminary findings have recently been presented in connection with the UN Conference on Biological Diversity in Curitiba, Brazil.
The situation is expected to become particularly dramatic at middle to high altitudes in mountainous area
Yesterday, at the end of a 153-day and 400-million km cruise into the inner Solar System beginning with its launch on 9 November 2005, ESA’s Venus Express space probe fired its main engine at 09:17 CEST for a 50-minute burn, which brought it into orbit around Venus.
With this firing, the probe reduced its relative velocity toward the planet from 29,000 to about 25,000 km/h and was captured by its gravity field. This orbit insertion manoeuvre was a complete success.

Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. This might explain why patients with malaria are susceptible to a wide range of other infections and fail to respond to several vaccines. In a study published today in the open access journal Journal of Biology (http://jbiol.com/), researchers show that if dendritic cells, the key cells involved in initiating immunity, are exposed to red blood cells inf
Researchers supported by the National Institute of Dental and Craniofacial Research, part of the National Institutes of Health, report today their initial success using a customized optical device that allows dentists to visualize in a completely new way whether a patient might have a developing oral cancer.
Called a Visually Enhanced Lesion Scope (VELScope), this simple, hand-held device emits a cone of blue light into the mouth that excites various molecules within our cells
Hot fudge sundaes and french fries aside, new research suggests obesity is due at least in part to an attraction between leptin, the hormone that signals the brain when to stop eating, and a protein more recently associated with heart disease. Reporting in Nature Medicine, University of Pittsburgh researchers provide evidence that C-reactive protein (CRP) not only binds to leptin but its hold impairs leptin’s role in controlling appetite. The results may help explain why obese people have so m
Older men who drink as few as two drinks twice a week and also have diseases that could be worsened by alcohol or cause problems with medications taken while drinking alcohol have higher death rates, as compared to men who either drink less or may drink more but don’t have such comorbidities.
Examining data from a 1971–74 health survey and a follow-up survey in 1992, the researchers found that older men who drank moderately or heavily and had accompanying comorbiditi
A bacterium that lives in rivers, streams and human aqueducts uses nature’s strongest glue to stay in one place, according to new research by Indiana University Bloomington and Brown University scientists reported in next week’s (April 11) Proceedings of the National Academy of Sciences.
The scientists found they had to apply a force of about 1 micronewton to remove a single Caulobacter crescentus from a glass pipette. Because C. crescentus is so small, the pulling f
Varied gene signatures in multiple myeloma cells predict different outcomes, provide treatment targets
Scientists at Dana-Farber Cancer Institute and collaborators have identified four distinct genetic subtypes of multiple myeloma, a deadly blood cancer, that have different prognoses and might be treated most effectively with drugs specifically targeted to those subtypes.
A new computational tool based on an algorithm designed to recognize human faces plucked the fou
The same signal responsible for promoting the type of immune responses that cause asthma and allergy can also limit the type of inflammation associated with debilitating diseases like inflammatory bowel disease, arthritis and multiple sclerosis, according to researchers from the University of Pennsylvania School of Veterinary Medicine. The researchers discovered how IL-25, a signaling protein known as a cytokine, both prevents destructive inflammation and promotes immune responses associated with
People who have had near death experiences often have different arousal systems controlling the sleep-wake states than people who have not had a near death experience, according to a new study published in the April 11, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology.
For the study, a near death experience was defined as a time during a life-threatening episode of danger such as a car accident or heart attack when a person experienced a var
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week’s online edition of Proceedings of the National Academy of Sciences.
The authors, including Bruce Hungate of Northern Arizona University and lead author Kees-Jan van Groenigen of UC Davis, discovered that plants are limited in their impact on global warming because of their dependence on nitrogen and other trace elements. These elements are e
