One in 14 men having a heart attack drive themselves to hospital

... symptoms first started. But only one per cent got behind the wheel and drove to the hospital. "Driving during a heart attack is obviously extremely dangerous for both the driver and the general public" says lead author Sharon O'Donnell from the City's Trinity College. "People who drove themselves to the ...

Protein receptor cools passion of 'kiss and run' nerve cells

...Until recently, the neuroscience field was solidly behind the idea that these little packets, or vesicles, either released all or none of their neurotransmitter into the synaptic cleft," said Alford. "We've identified a specific molecular mechanism that targets the machinery that causes the fusion process a...

Contaminants linked to sturgeon decline in Columbia river

...rchers found some of the fish living in reservoirs behind the dams had concentrations of chemicals up to 20 ...ontamination was most significant in the reservoir behind the Bonneville Dam, the oldest dam on the river. "We believe that some contaminants are accumulati...

Possible brain hormone may unlock mystery of hibernation

...nation hormone in the brain may unlock the mystery behind the dormant state, researchers reported in the April 7, 2006 issue of Cell. Hibernation allows animals from bears to rodents to survive unscathed--in a state of suspended animation--under the harshest of winter conditions. If the findings in chipmun...

New crop of technology reveals plant health

...ant care to precision agriculture. "The main idea behind PLANTS is to develop a system that produces the optimal growing conditions for a crop, so that crops are kept in the best possible health with the minimum of inputs," says Dr Fiona Tooke of the Eden Project, one of the project partners. "It promotes ...

Study reveals mass migration of mormon crickets driven by hunger, fear

...ick D. Lorch, have revealed the motivating factors behind the seasonal mass migration of Mormon crickets in ...mentation to determine that two driving forces are behind the migration: a need for protein and a fear of cannibalism. Their results reveal a different mod...

Alaska seal pup diet may hold key to decline of population

...hich diet group they were put in, continued to lag behind in weight gain and even lost blubber depth. "Our longitudinal study is leading to a better understanding of the role that fat consumption plays in the life of the harbor seal and could tie the declining population of seals and other marine mammals w...

Just the expectation of a mirthful laughter experience boosts endorphins 27 percent, HGH 87 percent

...hter feels good, but is there real neurophysiology behind it and what can you do about it? In a paper being presented in an American Physiological Society session at Experimental Biology 2006, Lee S. Berk of Loma Linda University, reports that not only is there real science and psychophysiology, but just t...

Discovery may speed forest biotechnology

...normal sexual crosses, remove the FT gene to leave behind trees that no longer have it, nor reproduce abnormally early. In other cases, a modestly strong FT gene might be left in place to provide sustained benefits, such as earlier or more heavily flowering fruit tree varieties. Especially in situations wh...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...nto the esophagus. That causes a burning sensation behind the breastbone or acidic fluid surging up into the mouth. So it might seem logical to think that if a particular food has been shown to cause a loosening of the sphincter, then eliminating that food from your diet would allow the sphincter to tighten...

Purdue creates new low-cost system to detect bacteria

...tern of scattered light is projected onto a screen behind the petri dish. This "light-scatter pattern" is recorded with a digital camera and analyzed with sophisticated software to identify the types of bacteria growing in colonies. "There are potentially thousands of applications for this new technology,...

DOE JGI sequences, releases genome of symbiotic tree fungus

...ween trees and fungi," said Martin. Key factors behind the ability of trees to generate large amounts of biomass or store carbon reside in the way that they interact with soil microbes known as mycorrhizal fungi, which excel at procuring necessary, but scarce, nutrients such as phosphate and nitrogen. Wh...

Scientists stop autoimmune disease without shutting off immune system

...mune response, if we can understand the mechanisms behind the damage it causes, we can block that damage," said Dr. David S. Rubenstein, associate professor in the departments of dermatology and pathology in the UNC School of Medicine and a member of the UNC Lineberger Comprehensive Cancer Center. "Targetin...

Mass. General study finds potential ovarian cancer stem cells

... potential ovarian cancer stem cells, which may be behind the difficulty of treating these tumors with standard chemotherapy. Understanding more about the stem-like characteristics of these cells could lead to new approaches to treating ovarian cancer, which kills more than 16,000 U.S. women annually and i...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

...es that could be used around the world. "The idea behind it is that you can control various conditions to try to make these stem cells become the cells you want," Abilez said. "Our goal is to take the mouse stem cells and find the conditions that will make the stem cells into smooth muscle cells (myocytes)...

'Sticky' mice lead to discovery of new cause of neurodegenerative disease

... The Jackson Laboratory point to a novel mechanism behind the buildup of the toxic sludge that accumulates i...a fundamental defect in protein synthesis could be behind the neurodegeneration they had observed in sticky mice. "There were a lot of candidate genes in the ...

Gene first linked to rare disease may trigger skin cancer, other tumors

...a role for CYLD in inflammation, but the mechanism behind the gene's control over tumor growth had remained uncertain. A team led by Reinhard Fässler of the Max Planck Institute of Biochemistry in Germany and his colleagues has now found that CYLD has a second role that explains its ability to keep tumors ...

T cells activated to fight HIV basis for dendritic cell therapeutic vaccine

...sburgh researchers. In essence, that's the concept behind the development of a novel therapeutic vaccine loaded with a patient's own souped up dendritic cells, which have been galvanized to rally other cells of the immune system in fighting the virus unique to that individual. At the XVI International AID...

Molecular DNA switch found to be the same for all life

"We had solved our initiator structures in the E.coli study just as results were being generated from the Botchan and Nog...
