Got heart disease? The answer may be in your fingertips
...n the study, researchers investigated the value of reactive hyperemia peripheral arterial tonometry (RH-PAT) by using a fingertip probe to assess the relationship between dysfunction in the heart region and dysfunction in extremities. Through invasive testing in the catheterization lab of the 94 patients par...Multi-center study finds therapy boosts kidney transplants in 'highly sensitized' patients
...ee of sensitization is measured in terms of "panel reactive antibody" or PRA levels. For a non-sensitized patient with end-stage renal disease, the wait time for a cadaveric transplantation averages four to five years. For sensitized patients, the odds of being transplanted drop. According to the article, "th...Research in yeast yields missing link in DNA maintenance machinery
...inaccessible. If DNA becomes damaged by radiation, reactive chemicals or ultraviolet light, for example, it must be repaired. But the bulky repair proteins need to gain access to the damaged areas of DNA. That's where INO80 chromatin remodeling might comes in. Its role, discovered by Shen and his colleagues, ...Climate change and the future of air travel
...il reduction strategy would work better if it were reactive on a daily basis. They also found days when the atmospheric conditions made it almost impossible to avoid contrail formation. Aircraft already measure the exterior air conditions, so a simple piece of software, programmed with the details of the jet...Chemicals in apples could reduce the risk of breast cancer, Cornell study in rats suggests
...ing free radicals and inhibiting the production of reactive substances that could damage normal cells. "Studies increasingly provide evidence that it is the additive and synergistic effects of the phytochemicals present in fruits and vegetables that are responsible for their potent antioxidant and anticancer ...Tumor-targeted immune cells cure prostate cancer in mice without causing systemic immune suppression
... In summary, these CD8+ T cells were specifically reactive against tumor tissues. Second, they were insensitive to TGF-beta. The two properties endowed the CD8+T cells with the ability to infiltrate tumor tissues and function as potent effectors against tumor cells. Finally, these cells were able to persist ...Medical molecules designed to respond to visible light that can penetrate tissue
... Os and Ru polyazine light absorbers and Rh and Pt reactive sites: Applications in solar energy conversion and photodynamic therapy (INOR 410)," will be presented at 4:50 p.m. Monday, March 14, in Convention Center Room 4. Co-authors are chemistry Ph.D. students Mark Elvington of Blacksburg, Va. and Ran Miao ...New study in 'Nature' demonstrates protection against cell death during heart attack
...en flow is re-established there is a huge burst of reactive oxygen, and that's when cells die. We hypothesize that if, at the same time you re-establish flow you infuse a cyclophilin D inhibitor, you might profoundly affect the heart or brain and, presumably, protect it." A class of drugs already exists that ...
