One-third of adults with diabetes still don't know they have it

...can often prevent or delay diabetes if they lose a modest amount of weight by cutting calories in their diet and increasing physical activity (for example, walking 30 minutes a day 5 days a week). A major study of people with IGT has shown that lifestyle changes leading to a 5 to 7 percent weight loss lowe...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...-reactive avian-influenza based vaccines with even modest immunogenicity in humans are important," said Macken, an influenza researcher in the Los Alamos Theoretical Division. Ideally, both vaccine strategies would be done in parallel: Stockpile a modestly effective vaccine to use while the better matched o...

p53, tumor suppression and aging

...pe p53 activity. The researchers found that even a modest decrease (about 20%) in Mdm2 effectively prevents tumor formation and does not lead to premature aging. Dr. Perry emphasizes that "many people develop cancer at a young age due to increased expression of Mdm2. The possibility that inhibitors of Mdm...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...king biochemical pathways: glycolysis, which makes modest amounts of ATP by breaking down the glucose without using oxygen; and the TCA cycle in the mitochondrion, which normally uses oxygen to produce large amounts of ATP by processing a byproduct of glycolysis. The disruption of this link blocks the ten...

Multi-million pound UK Biobank underway

...risk factors together, each of which may have only modest effects on the likelihood of getting some particular disease." Taking part will involve the first volunteers spending about an hour at an assessment centre in Altrincham, Cheshire, answering some questions, having some standard measurements taken an...

Cure for cancer worth $50 trillion

...versity of Chicago researchers, estimate that even modest advancements against major diseases would have a significant impact ?a 1 percent reduction in mortality from cancer has a value to Americans of nearly $500 billion. A cure for cancer would be worth about $50 trillion. "We distinguish two types of he...

Free HIV tests cheaper than charging when goal is preventing AIDS

...aid. The free testing period was promoted with a modest advertising campaign. Once the free trial began, KIWAKKUKI's AIDS Information Center was deluged with clients. "Our colleagues at KIWAKKUKI called it the 'crash' period because it was kind of crazy," Thielman said, with nearly four times as many peop...

Poison + water = hydrogen. New microbial genome shows how

...while other organisms may have the equivalent of a modest mixing bowl to process their supper of carbon monoxide, this species has a veritable food processor, letting it gorge on a hot spring buffet all day. "The findings show the continued value of microbial genome sequencing for exploring the useful cap...

Technique offers new view of dynamic biological landscape

...aced a significant hurdle: Even yeast's relatively modest 6,000 genes would generate nearly 20 million possible gene pairs that would need to be tested. To narrow the number of possible interactions, they adopted a strategy called neighborhood clustering, which restricts analysis to genes that have related ...

A New Era of Hope for the World's Most Neglected Diseases

...loping their own treatments and vaccines with only modest technical or financial assistance from more developed countries. Secondly, in addition to the expectation that new tools will be developed to control neglected diseases, there is a surge of interest in maximizing the effectiveness of existing tools....

Chernobyl: The true scale of the accident

...ery complications or overall health of children. A modest but steady increase in reported congenital malformations in both contaminated and uncontaminated areas of Belarus appears related to better reporting, not radiation. Did the trauma of rapid relocation cause persistent psychological or mental health ...

What Makes The Brain Tick, Tick, Tick: Researchers Gaining New Insights Into Brain's Internal Clock

...ry excited about our success so far, we want to be modest about our capabilities. We are blind men touching just one part of this elephant that is time. "And our new review paper, to the best of our knowledge, is the first to try to integrate the different fields and levels of analysis that contribute to u...

DOE's Office of Science sets up program to aid scientists displaced by Hurricane Katrina

...e of Science will consider on a case-by-case basis modest supplemental funding to existing programs in order to facilitate this process. Displaced students and faculty researchers from affected universities will be able to indicate their interest in being hosted by a grant recipient and complete their requ...

Suppressing growth hormone in early adulthood may prevent cancer

A modest suppression of growth hormone and related compound...incidence of cancer in these rats, we found that a modest suppression of plasma IGF-1 beginning shortly after puberty and continued throughout life reduces th...

Digging in the dirt for life's biochemical foundations

...ts. Many had assumed that the fungus would play a modest role. The team found, however, that the fungus acts more like a four-lane highway than a two-track country road in shuttling the nitrogen into plant roots. More than a third of the total nitrogen taken up by the plants came by way of the fungus, Shac...

Rodent social behavior encoded in junk DNA

... similar to that of humans. Two studies have found modest associations between alterations in this microsatellite and autism in some families. As subgroups of autism spectrum disorders are characterized, a stronger connection may emerge. Far from being junk, the repetitive DNA sequences, which are highly p...

New type of rejection blocker protects kidneys after transplant

...n. However, Vincenti said, advances have only been modest in terms of keeping the organ healthy over the course of years. Paradoxically, anti-rejection drugs like cyclosporine contribute to health problems including cardiovascular disease -- the leading cause of death among kidney transplant recipients. "T...

Researchers extend mouse lifespan by protecting against free radicals

...alase levels in the nucleus and cytoplasm saw only modest increases in lifespan. These results fit with the theory that mitochondria can be an important source of free radicals created as a byproduct of energy production. Removing hydrogen peroxide "at the source" seems to be the most effective strategy for...

The making and breaking of microtubules

...ained for the polymerization intermediates at more modest resolution, Nogales and Wang have been able to see changes in tubulin molecules, just how their capacity to interact with other molecules is altered by binding to GTP or GDP, and how these alterations control bending and flexibility. They found that...

Human Cells Filmed Instantly Messaging for First Time

...uced today, could be achieved with only relatively modest changes in land use and agricultural and forestry practices. "One of the main points of the report is that the United States can produce nearly 1 billion dry tons of biomass annually from agricultural lands and still continue to meet food, feed and ...
