Halving daily cigarette quota has no health benefit

...nly had slightly lower death rates from all causes combined than the heavy smokers during the first 15 years. ...ck actually had higher death rates from all causes combined than heavy smokers. The authors conclude that long term monitoring provides no evidence that hea...

H9N2 avian flu vaccine paired with adjuvant provokes strong human immune response at low doses

When combined with an immune-boosting substance called an adjuvant, low doses of an experimental vaccine against a strain of avian influenza (H9N2) provoked a strong antibody response in human volunteers, report scientists supported by the National Institute of Al...

Researchers add to understanding of how brain cells communicate

...that variation in how ions interact with receptors combined with variation in the structure of receptors is responsible for specialization of receptor function. "This research helps explain how evolution accomplished a critical goal: producing receptor proteins with finely tuned properties that help optimi...

Pair of microRNA molecules controls major oncogene in most common leukemia

...c leukemia, he said. These molecules could also be combined with 12 other miRNAs known to be associated with B-CLL to provide a test that may help determine prognosis and treatment, he said. Researchers at Ohio State have been leaders in characterizing the role of miRNAs in cancer development. These small...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...create a precise map of the brain's structure, and combined that with their PET scans to find the exact areas of dopamine activity. The volunteers answered questions from two standardized questionnaires repeatedly both in a control (no pain) state and when their jaw muscles were being injected with harmle...

Researchers image molecular motor structural changes

...e of the motor molecule bound to a microtubule, we combined the images generated by high-resolution electron m...archers then took those high-resolution models and combined them with models of kinesin and microtubule structures rendered using another technology, x-ray crys...

Altered perception of reward in human cocaine addiction

...benefit of using sophisticated brain-imaging tools combined with sensitive behavioral, cognitive, and emotional probes to optimize the study of drug addiction, a psychopathology that these tools have helped to identify as a disorder of the brain." Goldstein will present details of these studies at a press ...

Abnormal overexpression of p53 is a predictive molecular biomarker

...dvexin has also achieved 100 percent response when combined with chemotherapy to treat locally advanced breast cancer, and a 69 percent response when used with radiation to treat non-small cell lung cancer. ...

Chemical tests of cell growth enter third dimension

...es, Yang took the basic concept behind the FBB and combined it with laboratory testing methods that normally only grow cells in two dimensions. Such tests are normally done on cells in trays containing many tiny wells. Each well contains a growth medium and some cells, and a protein that will cause growing c...

New engineered drug may offer prolonged arthritis relief

...t clumps together at normal body temperatures. The combined drug likewise would assemble into clumps in the body to serve as "drug depots" that gradually release active drug particles, the researchers said. "Although the conventional drug is being used for autoimmune diseases, no one yet knows how much of i...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

...n the course of the disease." The Cornell study combined cutting edge "proteomics" technology, detailed image analysis, and complex computational and statistical analyses to simultaneously compare 2,000 cerebrospinal fluid proteins from 34 patients with autopsy-proven Alzheimer's disease to those of 34 age...

LSU professor discovers new species

...and significant genetic variations. These traits combined to confirm the original hypothesis that the lizard was, in fact, an entirely new species. Austin spent the entire summer of 2006 in New Guinea, his geographical area of expertise, conducting fieldwork with graduate students. He is currently working...

Distinguishing friend from foe in the battle against cancer

...ting cell division and in clinical trials has been combined with other drugs to halt cancer cell growth. But to cancer cells, rapamycin is both friend and foe. "Rapamycin is not as successful as initially expected in treating cancer," explains Ghosh. "Instead of killing cells, you end up triggering a surviv...

Rising ocean temperatures, pollution have oysters in hot water

...an water temperatures and increased pollution have combined to reduce the oyster population to 5% of what it was 200 years ago, Sokolova said. The loss of oysters has far-reaching environmental implications. "We can't even imagine the expanse of oyster reefs 100-200 years ago and their impact on the ecosys...

A new target for painkillers

...covery eventually leads to a new pain drug that is combined with existing treatments, "you may be able to reduce the pain to a lower level than ever before. No one drug is going to fully treat all pain, so having a new way is like having a backup catcher if the first catcher misses the ball." How the Study...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...timulates osteoblasts, enhancing bone formation. A combined treatment will not only prevent the occurrence of osteoporosis, but also make the quality of bone even better. "Our discovery proves that inhibiting osteoclasts while simultaneously stimulating new bone formation can be done." Bone health is ...

Rescuing injured hearts by enhancing regeneration

...t the heart from scarring. Working with rats, they combined an agent that overcomes a natural inhibitor of cell division with a naturally occurring growth factor that encourages blood vessel growth (angiogenesis). Together, these two agents enabled heart-muscle cells to multiply and the heart to regain its fu...

Vaccination with embryonic stem cells prevents lung cancer in mice

...embryos). The other vaccine consisted of the ESCs combined with cultured fibroblast cells producing GM-CSF, a growth factor usually made by white blood cells and blood vessel-lining endothelial cells, which "supercharges" the immune response and appears to enhance the vaccine-induced immunity to cancer. P...

Discovery of the first resistance gene to rice yellow mottle virus

...e viral proteins. The two approaches are now being combined in order to determine the molecular mechanisms of resistance or susceptibility on the basis of direct interactions between the rice protein and that of the virus. Understanding of these mechanisms will give clues as to the best ways of making long-te...

Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census

...aur genera that walked the earth. Their findings, combined with previous studies suggest that nearly half of all dinosaur genera that existed did not leave behind fossils that could be found. "I would never suggest that this prediction, however statistically sound, is the final word on dinosaur diversity," ...
