Researchers discover inherited mutation for leukemia

...e occurs later that turns the gene off altogether, leading to leukemia. This latter alteration is a chemical change that is not inherited. The findings could help identify people at risk for chronic leukemia, but they also may provide new insights into the process of natural cell death. They may even lea...

Discovery in orange cauliflower may lead to more nutritious crops

...es, leads to compromised immune systems and is the leading cause of blindness in children. "A large percentage of the human population depends on staple crops for nutrition," said Li, an adjunct assistant professor in the Department of Plant Breeding and Genetics and a scientist at the U.S. Department of A...

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

...ompound orally in order to curb his appetite, thus leading to natural weight loss. In experiments with mice, it was shown that a single oral administration of BL-3020 led to reduced consumption over a period of 24 hours. Over a 12-day period of daily dosages, the mice weighed 40 percent less than the average...

Columbine flowers develop long nectar spurs in response to pollinators

...tion of the length of nectar spurs--the long tubes leading to plants' nectar--happens in a way that allows flowers to match the tongue lengths of the pollinators that drink their nectar, biologists have found. The researchers were Justen Whittall of the University of California at Davis and Scott Hodges of ...

U-M researchers discover gene switched off in cancer can be turned on

...ted about the potential this finding could have in leading to new targets for cancer treatment. “This is a targetable target. We can detect it, but we need to find a better way to turn it back on. No drugs are designed to deal with a gene that’s turned off. But it’s a straightforward extension of current ...

Researchers examine carbon capture and storage to combat global warming

... path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming. Carbon capture and storage, also called carbon sequestration, traps carbon dioxide after it is produced and injects it underground. The gas never enters the atmosphere. The practice could transform heavy ca...

Newly discovered antibody may be body's natural defense against Alzheimer's

... NewYork-Presbyterian/Weill Cornell is currently leading a six-month Phase II study of IVIG in 24 patients with mild and moderate Alzheimer's disease, which is planned to be complete later this year. While this study may provide a signal of the effect of IVIG therapy to clinical outcomes, further investiga...

Could fungal collection hold the key to new life-saving drugs?

...ht MRSA, cancers and other diseases, after CABI, a leading bioservices organisation announced that its fungal collection will be screened by the University of Strathclyde. CABI houses one of the world’s largest genetic resource collections of fungi, numbered at over 28,000 strains, including Fleming’s origi...

Marine phytoplankton changes form to protect itself from different predators

If consumed by smaller creatures like ciliates, less of the carbon sinks to the deep sea and more remains in the surface waters. “This could alter the flow of energy and nutrients from deep to shallow, depending on what might be t...

Some genes, however, are evolving rapidly, leading the team to suspect they include key genes involved in interacting with the human host - where the battle between parasite and patient is fought and where rapid response is important to both. Remarkably, L. braziliensis, the most ancient Leishmani...

Clot-dissolving agent may be beneficial in treatment of severe frostbite

...imulates clotting that blocks small blood vessels, leading to cell death. Because tPA reverses this clotting, blood flow is restored before permanent damage is done. “Based on the dramatic improvements in perfusion [blood flow] and reduction in rates of amputations when tPA was administered within 24 hour...

Researchers identify protein pathway involved in Parkinson disease development

...owever, the protective TRAP1 pathway is disrupted, leading to mitochondrial damage. Other scientists recently have linked early onset Parkinson disease to mutations in both copies of the PINK1 gene (one from each parent). They also have evidence that single-copy mutations in PINK1 are a significant risk ...

Surprising origin of cell's internal highways

...Golgi are directed toward the cell "front," or the leading edge, of motile cells. Since such an orientation is needed for directional migration, Kaverina hypothesizes that this subset of microtubules may influence cell motility by facilitating the transport of proteins needed for movement to the cell front. ...

Researchers develop buckyballs to fight allergy

...rapies for allergy. Allergic disease is the sixth leading cause of chronic disease in the United States, and while various treatments have been developed to control allergy, no cure has been found. These findings advance the emerging field of medicine known as nanoimmunology. The researchers, from Virgin...

Male circumcision overstated as prevention tool against AIDS

When this artificial weighting was removed Talbott found that circumcision was no longer statistically significant in explaining the variance in AIDS in...

Smoking rate has plummeted in New York City

There aren’t many programs that can prevent 80,000 premature deaths this quickly.” Ads from the 2006 campaign graphically depicted tobacco smoke’s effects on the brain, lungs and arteries, showing testimonials from si...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

This study was announced at the leading influenza conference, Options for the Control of Influenza VI, in Toronto.1 The reality is that country stockpiles of Tamiflu are limited and are targeted at treatment only rather than treatment and prevention.2 However, some governments are now pl...

Creswell said Lieberman has now shown in a seri...

New vaccine prevents CMV infection and disease in mice

...nd disease. CMV, a type of herpes virus, is the leading viral cause of birth defects and a serious problem in patients with compromised immune systems. The body’s natural immunity doesn’t protect against infection by the virus, estimated to be present in 50 to 75 percent of all adults. “Until now, s...
