Defines Dead Spot More Clearly

In 1998, researchers at the University of Maryland discovered a new disease of creeping bentgrass caused by an unidentified species of Ophiosphaerella. Through morphological and molecular study, it was shown that the pathogen constituted a new species, Ophiosphaerella agrostis, and the disease was named bentgrass dead spot. Subsequently, O. agrostis was found in Texas and Florida causing dead s...

Seeing more clearly: recent advances in understanding retinal circuitry.

Among 10 breakthroughs that Science announced at the end of 2002 was the discovery of a photosensing (melanopsin-containing) retinal ganglion cell (RGC) and its role in entraining the circadian clock. This breakthrough exemplifies the ultimate goal of neuroscience: to understand the nervous system from molecules to behavior. Light-sensing RGCs constitute one of a dozen discrete RGC populations ...

A revised protocol for more clearly classifying a nonunion.

Classifying a nonunion solely on the extent of callus formation on a radiograph is insufficient. We have conducted a study with a revised protocol to classify a nonunion more clearly, which uses both radiographic observation and fixation stability. 47 consecutive femoral shaft nonunions were studied using this protocol and 42 nonunions were followed up for at least one year after discovery (ran...
