Secret of smallpox's success may lead to bioterror cure

... call a 'pathogen associated molecular pattern' ?a biomarker that is only present in your body when you are infected with a virus and that the body knows to look for and respond to," said Jacobs. "The body responds in a lot of different ways, but the main way is it starts producing an immune response ?double-s...

The team, which included scientists from USC, Caltech, the University of Maryland and a Brazilian mining company, identified "a complex and productive m...

Researchers identify genes associated with lung transplant rejection

...rger, separate set of patients to prove that these biomarker genes actually work. And we're testing that now." Currently, Caughey's research team is studying biopsy samples from more than 100 UCSF lung transplant patients, who regularly undergo biopsies as part of standard follow-up care. Another potential be...

Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

...valuation, and any leftover was frozen so that the biomarker concentrations could later be measured. The infants were then tracked until 1 year of age to determine whether any were subsequently diagnosed as being abused. Researchers were then able to determine how well the biomarkers established which children...

Aging cells, aging body: Fresh evidence for a connection

...ng. For replicative senescence, the most important biomarker is telomere dysfunction-induced foci, or TIFs. Presence of these structures signals that the protective chromosome caps called telomeres have dwindled enough to halt cell division. Scientists painstakingly counted the cells with aging biomarkers. Wh...

'Smart' genetic therapy helps the body to heal itself

... SMN2 levels in their blood. With the help of a biomarker we hope we will be able to distinguish between patients who will respond to this drug and which will not." The results show that valproate is able to exert a direct effect on the activity of the human SMN gene, says Professor Wirth, but it is still ...
