Obturator Anterior Dislocation After Direct Anterior Total Hip Arthroplasty in a Patient with Ehlers-Danlos Syndrome: A Case Report.

Case: A 71-year-old woman with Ehlers-Danlos syndrome suffered an atraumatic obturator dislocation status post direct anterior total hip arthroplasty. A closed reduction under conscious sedation was attempted, but was unsuccessful. Repeat closed reduction under full general anesthesia with paralysis and fluoroscopic guidance was successful at reducing the femoral prosthesis out of the pelvis and back into an appropriate position.

Length and colonization rates of roots associated with arbuscular or ectomycorrhizal fungi decline differentially with depth in two northern hardwood forests.

Ectomycorrhizal (EM) and arbuscular mycorrhizal (AM) fungi are often studied independently, and thus little is known regarding differences in vertical distribution of these two groups in forests where they co-occur. We sampled roots at two soil depths in two northern hardwood stands in Bartlett, New Hampshire, co-dominated by tree species that associate with AM or EM fungi. Root length of both groups declined with depth.

Optimizing single-mode collection from pointlike sources of single photons with adaptive optics.

The collection efficiency of light from a point-like emitter may be extremely poor due to aberrations induced by collection optics and the emission distribution of the source. Analyzing the aberrant wavefront (e.g.
