Researchers release new variety of asparagus

...ketable spears. Higher yield of marketable spears reduces the impact of high land and labor costs, thereby making the asparagus more profitable without raising consumer prices. Named "DePaoli" after William P. DePaoli, the first manager of the California Asparagus Commission who long supported the aspar...

Lactic acid not athlete's poison, but an energy source - if you know how to use it

...99, for example, he showed that endurance training reduces blood levels of lactate, even while cells continue to produce the same amount of lactate. This implied that, somehow, cells adapt during training to put out less waste product. He postulated an "intracellular lactate shuttle" that transports lactate ...

Access to antiretrovirals unlikely to reduce HIV infection rates

...trovirals therapy (ART) slows AIDS progression and reduces viral load in infected individuals, the drugs not only improve the health and prolong the life of those who take them, but also make it less likely that they infect others. As a consequence, ART has been discussed not only as a treatment but also as ...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...unately, a major shortcut has been discovered that reduces the workload about 30-fold. The International HapMap Project, led by the NIH and completed in October 2005, demonstrated that the 10 million variants cluster into local neighborhoods, called haplotypes, and that they can be accurately sampled by as f...

Study shows that cells have a natural defense against HIV

... of HIV cDNA in cells," Fishel says. "This process reduces the pool of HIV cDNA that can integrate into host chromosomes, thereby protecting cells from infection." The researchers are now working to learn how the proteins destroy the HIV cDNA. These studies could lead to drugs that might help the proteins ...

Molecular mechanism may explain how fevers spark seizures

...lem." The team's discovery that high temperature reduces cell surface GABA-A receptor levels "raises the idea that one could develop a treatment for vulnerable patients that would prevent them from developing febrile seizures and possibly epilepsy," Macdonald said. Vulnerable patients include children who ...

UMaine teams with fishermen to study affects of trawling on seafloor ecology

...plex habitat and it is clear that rock hopper gear reduces habitat complexity," said Watling. "No good habitat, hardly any fish." The good news is that recently protected habitats are recovering. While anything resembling a "natural" condition would certainly be far in the future, Knight found that signific...

Creation of antibiotic in test tube holds promise for better antibiotics

...-causing bacteria. Hitting on at least two targets reduces the risk of resistance occurring, van der Donk said. The researchers synthesized nisin simply in a test tube by using a single cyclase enzyme to re-create the process that normally occurs in a strain of the bacterium Lactococcus lactis found natural...

'Dead zone' summer killed billions of ocean state mussels

...load and hypoxia by consuming phytoplankton, which reduces bottom-dwelling bacteria. "When we lose mussels, we may be losing the ability to prevent future dead zones from forming," Altieri said. "So these sorts of extinctions may trigger a downward spiral, with coastal zones less able to handle environmental...

Vital ocean prey play active role in environment

...rill in younger stages separate from adults, which reduces competition for food and lessens the chance that adults will prey on younger stages. Further studies of krill can lead to an improved picture of the Southern Ocean ecosystem, Nicol writes. ...

Free-radical busting antioxidants might not promote healthy hearts

...laboratory rodents with vascular disease. Probucol reduces the risk of heart disease in humans, but is no longer prescribed in the US and Australia because of adverse side effects: a tendency to lower good cholesterol along with the bad and the potential to induce an irregular heartbeat. Probucol is still av...

Ancient fossil DNA found preserved in crystal

...etter, as well, and the use of sodium hypochlorite reduces the possibility of modern contamination. The crystal aggregates act as a "privileged niche in fossil bone," protecting the DNA from hostile environments and leaving it relatively undamaged over time. The team's findings suggest that the DNA in thes...

Healing honey: The sweet evidence revealed

Molan of New Zealand's University Waikato. He noted that, although the many randomized controlled ...

US woman gives birth to baby from world's first frozen donor egg bank

...ceed. Also, the use of frozen donor eggs greatly reduces any of the current health hazards from infectious disease transmission present when using donor eggs that have not been frozen. Egg donors for CEI are tested as required by the FDA for infectious diseases within 30 days of egg collection. Additionall...

Study finds 60 new genes controlled by DNA snippet

...rt muscle cells' ability to contract. That in turn reduces the pumping strength of heart muscle and leads to heart failure, according to recent studies. Can cardiomyopathy be reversed by manipulating CArG-SRF? CArG sequences also appear near genes that direct the building of nerve cells and blood vessels, su...

Secrets of the sea yield stronger artificial bone

...te of this freezing process, the layered structure reduces in scale. Ultimately, they obtained a microstructure that measures one micron, or one-millionth of a meter. In comparison, nacre's structure measures half of a micron. "We are half a micron away from mimicking nature," says Tomsia. After the ice is...

Holloszy, M.D., professor of medicine at Washington University, demonstrated that stringent and consistent caloric ...

Experimental drug reverses key cognitive deficits, pathology in Alzheimer's

...the disease. What's more, the drug, called AF267B, reduces both of the pathologies--the brain-clogging buildup of protein "amyloid plaque" outside brain cells and the protein "neurofibrillary tangles" inside the cells. In an article in the March 2, 2006, issue of Neuron, Dr. Frank LaFerla of the University...

New fruit fly protein illuminates circadian response to light

...e hours," explains Sehgal. The mutated JET protein reduces the light-dependent degradation of TIM and the circadian response to light. Sehgal and others were able to reverse the behaviors in the jetlag flies by genetically replacing the mutated gene sequence with the normal sequence, which led to the produc...

Accordingly, this product candidate is shown to impede key detrimental events normally associated with Alzheimer's disease and which are believed to lead to severe consequences in the brain of the affected individuals."
