COLUMBUS, Ohio — Elderly people might not benefit from some of the tuberculosis vaccines currently in development, recent research suggests.
Some vaccines under study are designed to activate a specific molecule that is an early participant i…
“The high presence of microRNA 451 enhances the response to treatment with chemo-radiotherapy and increases the survival of patients with stomach cancer”, explained Dr. Jesús García-Foncillas, chief researcher of the Pharmacogenomics Laboratory at…
PASADENA, Calif. — We’ve all heard the predictions: e-commerce is going to be the death of traditional commerce; online shopping spells the end of the neighborhood brick-and-mortar store.
While it’s true that online commerce has had an impact on …
LOS ANGELES — Sept. 7, 2010 — Researchers in Cedars-Sinai’s Department of Psychiatry and Behavioral Neurosciences have reported people who undergo massage experience measureable changes in their body’s immune and endocrine response.
Although …
BIRMINGHAM, Ala. — Cigarette smoke shuts off a key enzyme in airways that regulates the body’s response to inflammation, according to findings from the University of Alabama at Birmingham published online today at Science Express.
The UAB rese…
Spanish researchers have calculated the probability of dying in road accidents on the basis of the time taken for the emergency services to arrive. Their conclusions are clear — reducing the time between an accident taking place and the arriva…
A team led by Massachusetts General Hospital (MGH) scientists has developed a new microfluidic tool for quickly and accurately isolating neutrophils — the most abundant type of white blood cell — from small blood samples, an accomplishment that …
NORFOLK, VA — Researchers have isolated a molecule, small enough to be used as a drug, that can shut down a dysfunctional immune response that causes deadly hemorrhagic shock, results in delayed death of heart attack patients, promotes rejection o…
Westminster, Colo. (August 26, 2010) — The term “macrophage” conjures images of a hungry white blood cell gobbling invading bacteria. However, macrophages do much more than that: Not only do they act as antimicrobial warriors, they also play cri…
Scientists at the University of Oregon have determined the fine-scale genetic structure of the first animal to show an evolutionary response to rapid climate change.
They used a high-throughput sequencing technique called Restriction-site As…
Tracing all the genetic changes that flow from a single mutation, UCSF scientists have identified the kinds of genes and systems in the body that ultimately allow a doubling of lifespan in the roundworm, C. elegans. Humans share many of these genes, and the researchers think the new findings offer clues to increasing human youthfulness and longevity as well.
Researchers at Kansas State University have successfully transplanted cells from one species to another without triggering an immune system rejection response or requiring drugs to suppress the immune system. This hopeful news for transplant medicine is reported in the online edition of the journal Experimental Neurology, published by Elsevier. Researchers transplanted umbilical cord matrix stem cells from a pig into the brain of a live rat, and for reasons they as yet do not understood, the recipient’s immune system did not detect nor reject the foreign cells, which survived for more than six weeks. No drugs were used to suppress the immune response.
