Two Chemical Compounds Restore Healthy Glucose Levels In Obese Mice

...m also previously identified the JNK gene as a key component linking inflammation to metabolic signaling and as a gene that interferes with insulin sensitivity. (http://www.hsph.harvard.edu /press/releases/press 11202002b.html. ER stress appears to trigger abnormal JNK activity, which is often seen in obesity...

New Study To Find Means Of Reducing The Risk Of Diabetes In Youth

...isis for this country. This important study is one component of a multi-faceted research agenda to address this dual epidemic, which threatens the health of our youth and the vitality of our health care system.” Participating schools will be randomly assigned to a program group, which implements the changes,...

Pest Control research Leads to Pain Control Discovery

... 'We used LPS as an inflammatory agent, which is a component of some bacterial cell walls,' said, co-author Steven Jinks. His laboratory examined the effects of these compounds in rodent inflammatory pain behavior models. 'Inflammatory mediators sensitize pain receptors and cause the animal to withdraw more qu...

Model of Internal Clocks Reveals How Jet Lag Disrupts the System

.... Then, following a slight delay, the intermediate component and some of the peripheral components overshoot as well, depending on their inherent circadian time and their connectivity with the master clock. For example, the peripheral components that already tend to lag actually try to catch up by backtracking...

AMD influenced by Variation in 3 Genes

...omosome 1, complement factor B (BF) and complement component 2 (C2) genes on chromosome 6, and the LOC gene on chromosome 10. They estimate that genotypes related to five variants in these three genes explain about half the sibling risk of AMD in the study population. Results are published online in Nature Gen...

Fruit fly’s visual map based entirely on genetic inputs

...boratories around the world. "There is a genetic component (to formation of the vertebrate visual system)," said Bellen, who is also a Howard Hughes Medical Institute investigator. "The neurons in vertebrates are born and are genetically programmed to project into a certain brain region. This is followed by ...

Novel Technique Would Prevent Re-Clogged Arteries

...o-drug is an amino acid that is a safe and natural component of all proteins. When the risk of restenosis abates, patients could simply stop taking the pro-drug, and the stent would stop manufacturing the drug. “This approach makes up a very general technological platform that can be applied for different me...

Gene Transfer Using Mutant Form of Good Cholesterol Cuts Vascular Plaque and Inflammation

...logy. Apolipoprotein A-I is a naturally occurring component of normal HDL (high-density lipoprotein), the “good” cholesterol that circulates in the blood stream. Apolipoprotein A-I Milano is a mutant form, which was originally found in a small number of individuals in Italy who appear to be protected from cho...

Three Molecular Triggers Threaten Leukemia Patients

...nd in newly diagnosed patients. Activation of each component - PKCa, pERK2 and pAKT - had an adverse effect on the patient's prospects that was independent of other traditional prognostic factors. Their cumulative impact was greater than simply adding their individual effects would suggest, the research team f...

New Study Suggests Perchlorate Effects on Thyroid Function of U.S. Women

...lth effects of perchlorate, an inorganic anion and component of rocket// fuel known to inhibit the thyroid’s ability to absorb iodine from the bloodstream, by recommending a new reference dose. The NAS also called for further research to identify safe exposure levels for sensitive subpopulations. Now, research...

Scientists Make World Breakthrough

...ial toxin kills cells by inactivating an essential component in the endoplasmic reticulum (ER). The latter is part of the cell that is essential for packaging newly-synthesized proteins. The toxin, called subtilase cytotoxin, is produced by certain strains of E. coli bacteria responsible for severe gastroint...

U.S., Australian Scientists Develop Vaccine Against Deadly Viruses

Toxin causing Gastrointestinal problems identified

...act. "It is unique because it cuts an essential component of the cell machinery in half, therefore disabling it," he said. The scientists have discovered how the toxin works and also its 3-D structure. This will be useful in development of treatments for toxin-related ailments. "This toxin belongs to t...

Combination of Herceptin and Hormonal therapy to Fight Cancer

... that Herceptin should be considered the essential component in the treatment of all HER2-positive breast cancers. It has been estimated that HER2-positive breast cancer affects up to 30 per cent of women with the complaint. This is an aggressive form of the disease where special and immediate attention is r...

Longer-Lived Rodents Have Lower Levels of Thyroid Hormone

...e (T3) in the presence of iodine. T3 is the active component of T4 and is the key hormone in regulating metabolism, Pinto said. When an animal becomes cold, for example, its body converts T4 to T3 to speed metabolism and warm the body, he explained. 'Mice strains that exhibit extended longevity tend to have ...
