In the migratory marathon, parasitized monarchs drop out early

...d with an increase of tropical milkweed species in milder climates, could ultimately replace the large migratory populations with smaller remnants that breed year-round and do not migrate. Study results suggest that if migration is lost from this system, remaining populations will become heavily parasitize...

Leprosy microbes lead scientists to immune discovery

...fections. The CD1b+ cells were present only in the milder form, indicating a successful battle against the leprosy bacterium. They were missing, however, in the more severe leprosy infections, meaning that the monocytes hadn't succeeded in producing those key anti-bacterial fighters. "The logic here is tha...

Activation of thermoreceptors mediates raw garlic's burning pungency

... heating, in correspondence with the significantly milder taste of roasted garlic. Garlic's pungency most likely evolved as a defense mechanism against browsing by animals, and indeed many animals--though clearly not all humans--are known to be repelled by it. The researchers include Lindsey J. Macpherson...

Ocean climate predicts elk population in Canadian Rockies

...ative NPO values. A positive NPO translates into a milder climate in most of western North America, but it means more severe weather in the mountain regions, where climate is more complex. Hebblewhite analyzed the elk population in Banff National Park from 1985 to 2000 and cross-referenced his results with...

Gene therapy advance treats hemophilia in mouse models

...normal protein level is needed to make the problem milder and, thus, less life threatening. "Hemophilia is considered an ideal candidate for correction with gene therapy because if you could just raise the factor VIII activity from less than 1 percent of normal to within 5 to 10 percent of normal, the ten...

Experimental shingles vaccine proves effective in nationwide study

... did get shingles, the episodes generally were far milder than they otherwise would have been." "For some people, shingles can result in months or even years of misery," comments study leader Michael N. Oxman, M.D., an infectious disease specialist at the San Diego VA Healthcare System and the University o...

Worms know bad food when they smell it

...ed enough of the bacteria, it can die quickly, but milder cases allow the worm to live for several days ?and head off in search of better food. So, the researchers surmised, knowing whether or not certain bacteria are toxic is something "worth learning" for the worm. To find out whether worms learn from ...

A salty tale: New bacterial genome sequenced from ancient salterns

...t. How could these microbes--which normally prefer milder environments--thrive in such high salt? To find out, TIGR researchers Emmanuel Mongodin and Karen Nelson, working with Canadian and Spanish colleagues, set out to sequence S. ruber's genome. In doing so, the scientists discovered evidence that the ...

Potential vaccine developed for deadly leishmaniasis disease

...he visceral, or internal, form of leishmaniasis. A milder form of leishmaniasis, which infects the skin, was reported among American military personnel during Operation Desert Storm and other conflicts in the region. Peter H. Seeberger, Ph.D., of the Laboratory for Organic Chemistry at the Swiss Federal In...

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

..., "though this might be the case for patients with milder heartburn symptoms who never walk into the doctor's office for advice." The cause of the conundrum lies in the nature of the studies that have been done. They generally looked at whether a particular food decreased the pressure exerted by the sphinc...

AIDS vaccine research offers new insights on survival

...AIDS virus, resulting in the development of a much milder form of the disease in vaccinated monkeys that subsequently become infected," he adds. "We know this because the loss of helper T-cells is much less dramatic, the amount of virus replication is much less and the infected animals go on to live longer....

Mutant gene causes severe kidney disease in infants

...in the embryo, so defects were present at birth. A milder mutation seemed to interfere with repair mechanisms in the glomerulus, so defects didn't show up until later in life." U-M scientists used DNA microarrays to analyze blood samples from 26 families around the world who had children diagnosed with s...

New study aims to stop sepsis in its tracks

...se in its early stages, it is often mistaken for a milder infection or other problems, said Angus. "A person may arrive with what looks like a simple case of pneumonia, and the emergency department team starts antibiotics and believes things will go well. Only when the blood pressure drops or is no longer r...

Hay fever can send work productivity down the drain

...lied on over-the-counter products to control their milder symptoms. A lack of sleep and a decrease in quality of life had the greatest impact on a person's ability to work, regardless of the treatment group they were in. Participants also cited watery eyes and sneezing as having a moderately negative eff...

Gene found for rare disorder may reveal new pathway in mental retardation

...ed one in 10,000 children. The disease varies from milder to more severe forms, but classically includes men... NIPBL gene, but who were judged to have CdLS or a milder variant of the disease, based on evaluations by clinical geneticists. Of the 115 patients, 11 ha...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

...each year with DMD or Becker Muscular Dystrophy, a milder form of the disease. The cause is a mutation, either inherited or occurring spontaneously, that affects a muscle protein called dystrophin. Spiegelman, whose laboratory discovered PGC-1alpha in 1998, led the new study which was aimed at determinin...
