Fat protein cuts blood vessel inflammation, may help heart, Jefferson scientists find
...mits researchers to illuminate blood vessels using fluorescent
signals, enabling them to see reductions in white cells on the vessel wall and subsequent lessening in inflammation. The scientists also looked at the effects of adiponectin on inflammation in normal mice. They gave mice a substance, TNF-alpha, wh...

Fingerprint instead of blood sample
...uently, a second antibody, which was tagged with a fluorescent
dye and binds specifically to cotinine antibodies, was applied to the fingerprint. Because there are many cotinine antibodies attached to each nanosphere, there is a significant amplification effect. Indeed, the ridge patterns of smokers fingerprint...
Slick and springy: Brown research reveals protein's role in joints

beads into two samples of synovial fluid. One sample was normal. The other came from a patient whose body doesn't produce lubricin. This rare condition, called CACP syndrome, causes premature joint failure, often prompting the need for joint replacem...
Sheffield scientists light up bacteria
...he new method will use a polymer which will give a fluorescent
