Special Imaging Study Shows Failing Hearts Are 'Energy Starved'

... energy deficits in failing hearts. The findings, published in the January 18 issue of the Proceedings of the National Academy of Sciences, confirm what many scientists have conjectured for years about heart failure, and suggest new treatments designed to reduce energy demand and/or augment energy transfer. ...

Children's taste sensitivity and food choices influenced by taste gene

...kes of children and parents." In the study, to be published in the February 2005 issue of Pediatrics, researchers compared taste sensitivity and food-related behaviors across three genotypes of the TAS2R38 gene, which encodes a taste receptor responsive to bitter taste. Using cheek swabs to obtain genetic sa...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

...n a forthcoming issue of Science. The results were published online April 28, 2005, in Science Express. The antibody-producing portion of the human immune system is broadly divided into two categories. The first, innate B cell immunity, comprises fast-acting but weak antibodies that fight a broad range of pat...

Researchers develop rapid diagnostic tool for pathogen identification

...agents. The new technology is addressed in a paper published in the February issue of the Centers for Disease Control and Prevention's (CDC) Emerging Infectious Diseases. This new platform is demonstrated in an assay that detects and discriminates 22 pathogens including viruses and bacteria that can present as...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...research is in February's Behavioral Neuroscience, published by the American Psychological Association (APA). The findings fit into a growing body of evidence that even a one-time infection can potentially permanently change physiological systems, a phenomenon called "perinatal programming." Understanding h...

Effective Cancer Treatments Follow The Clock

...inic Lerner Research Institute in Cleveland, Ohio, published its findings February 1, 2005, in the early online edition of the Proceedings of the National Academy of Sciences. In experiments, which were conducted in mice, the scientists found that the body's internal biological clock affects the survival of i...

Use of Insecticides Linked to Lasting Neurological Problems for Farmers

The research is part of the ongoing Agricultural Health Study funded by the National Institute of Environmental Health Sciences and the National Cancer Institute, two of the National Institutes ...

US life expectancy about to decline, researchers say

...sity did not exist. To do this, they used recently published health statistics and assumed that everyone who is currently obese acquired the body mass index of people who have the lowest risk of death. By calculating years-of-life-lost due to obesity and combining that with estimates of the prevalence of obes...

How the environment could be damaging men's reproductive health

...affecting men's reproductive health. The studies, published online today (Thursday 28 April) in Europe's leading reproductive medicine journal Human Reproduction, suggest that environmental pollutants could be changing the ratio of sperm carrying the X or Y (sex determining) chromosomes and that they could be...

NYU study reveals how brain's immune system fights viral encephalitis

...s fights viral infection of neurons. The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages--by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain....

Surprising findings reported about iron overload

...ngs in the five-year, 100,000-person study will be published tomorrow, April 28, in The New England Journal of Medicine (NEJM). The University of Alabama at Birmingham received $3.1 million of study funds to screen 20,000 people for the group of disorders called hemochromatosis and iron overload. Ronald T. Ac...

Live fast, die young true for forests too

...according to a U.S. Geological Survey (USGS) study published in a recent issue of the journal Ecology Letters. This discovery could help scientists predict how forests will respond to ongoing and future environmental changes. "One implication of this fast turnover rate is that the world¹s most productive fore...

Researchers discover molecular mechanism that desensitizes us to cold

...d so that one no longer feels the cold. The study, published this week as an advance online publication by Nature Neuroscience, focused on a specific region of the cold receptor which is found in many other receptors, including ones involved in taste, vision and fertilization. Therefore, the findings may have ...

Not-for-profit publishers call NIH public access rule a missed opportunity

...journals' full text articles and link to the final published articles residing on the journal websites. This would offer significantly more assistance to those seeking medical research results than a database of NIH-funded manuscripts can provide. This public-private partnership would be much less costly to NI...

Viral protein influences key cell-signaling pathway

...tein that it produces called p12. The research is published in the April issue of the journal AIDS Research and Human Retroviruses. The study found that p12 increases the activity of an important gene in host cells. That gene controls production of a cell protein called p300. The p300 protein, in turn, contr...
