Fee-for-service associated with a significantly higher rate of cataract surgery

A system in which physicians are reimbursed for each procedure they perform (fee-for-service) is associated with a significantly higher rate of cataract surgery and related surgical costs, compared to a system in which physicians receive a lump sum for each patient they manage (contact capitation), according to a study in the December issue of Archives of Ophthalmology.

CFH Y402H confers similar risk of soft drusen and both forms of advanced AMD

Gene is associated with increased risk of precursor of macular degeneration A variant in a gene called Complement Factor H (CFH) appears to contribute to the increased risk of advanced age-related macular degeneration (AMD) largely or entirely through its impact on the development of a precursor of advanced AMD called soft drusen (small yellowish, extracellular deposits of lipid, protein and cellular debris in the back of the eye), according to a multinational team of researchers.

Nanotechnology and biochemistry provide new way to study T cell signaling

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, combining nanotechnology with biochemistry, have created unique synthetic membranes that, for the first time ever, enable them to directly control signaling activity in living T cells from the immune system. Already their experiments have yielded surprising results.
