Gene thought to assist chemo may help cancer thrive

...l to successful chemotherapy. The idea is that p53 assists in killing the cancerous cells that the chemo treatment injures. But in this latest trial, Georgia Tech researchers found that p53 may be a “double-edged sword.?Chemotherapy patients whose tumors had a mutated p53 gene that didn't work had a much...

Loss of a universal tRNA feature reported

... DNA template. tRNAHis is the specific tRNA that assists in incorporating the amino acid histidine into new proteins. Histidine residues make essential contributions to protein structure as well as the catalytic mechanisms of enzymes and must be reliably incorporated during the process of translation. U...

Cardiologist's 'living chip' changes science of disease monitoring

...xcell Partners Inc. The Rochester-based consortium assists young companies with funding from New York state, ...ical Center's Office of Technology Transfer, which assists University researchers in developing new inventions, immediately saw the promise in Rosero's idea an...

Stimulation of the semicircular canals can artificially control human walking and balance

...ctures that are part of the vestibular system that assists in orientation and balance. The researchers found that artificial stimulation of semiciruclar canal nerves afforded "remote control" that was accurate enough to keep subjects on pathways and avoiding obstacles while walking blindfolded through botani...

More evidence mammals, fruit flies share make-up on function of biological clocks

...e time zones) in the lab. In mammals, however, Cry assists in the 24-hour rhythmic expression of clock genes and has nothing to do with re-setting the clock. The researchers sought to determine additional roles for Cry in fruit flies by testing the rhythmic expression of clock genes in flies with either a ...

Potential heart benefit found in stem cells

... in muscle tissue, and connexin 43, a protein that assists in intracellular interactions The in vitro data suggests that stem cells from this source have significant CM potential and are potentially valuable not only because they can be easily collected from young volunteers, but also because of their colle...

Common bacteria pirate natural mechanism to get inside cells

...li as a model to show how nitric oxide unwittingly assists bacterial uptake and survival. "In bladder cells, E. coli uses this mechanism to get inside the cells and hide from the antibiotic effect and the immune system," says Dr. Daaka. "We think their hiding is mediated through dynamin. This is not only ...

Software might revolutionize glucose monitoring in critically ill patients

... Making reports that GRIP, a computersoftware that assists in the monitoring of glucose levels incritically ill patients, saves nurses time and effort and is moreefficient than the paper-based method currently used in manyintensive care units (ICUs). Monitoring blood glucose levels isnecessary to avoid stres...

...on targets for destruction, said Dewhirst. "HIF-1 assists cancer cells in dying by a process of self-directed suicide called 'apoptosis,'" said Dewhirst. "If HIF-1 is inhibited prior to radiation, it will make the cell less sensitive to apoptosis and will thereby make the tumor cells more resistant to radia...

Chemical 'band-aid' prevents heart failure in mice with muscular dystrophy

...s where poloxamer 188 comes in," Metzger adds. "It assists the heart to be more compliant during the relaxation phase ?allowing more blood to flow into the heart. We demonstrated this effect at the level of individual heart muscle cells, and it turned out to be true at the organ level, also." The key to the...

New polysaccharide may help combat multidrug resistance in cancer

...le. In adult tissues it plays two roles. First, it assists in tissue hydration and in biophysical properties such as resilience. Second, it forms a template to which matrix proteins attach and form important extracellular structural complexes." Hyaluronan also accumulates around the outside of cells during ...

WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas
