A multicenter, prospective, randomized, double-blind, placebo-controlled clinical trial was conducted to test the efficacy of a specifically programmed, low-intensity, non-thermal, pulsed ultrasound medical device for shortening the time to radiographic healing of dorsally angulated fractures (negative volar angulation) of the distal aspect of the radius(More)
Pathogens are hypothesized to play an important role in the maintenance of tropical forest plant species richness. Notably, species richness may be promoted by incomplete filling of niche space due interactions of host populations with their pathogens. A potentially important group of pathogens are endophytic fungi, which asymptomatically colonize plants(More)
A low intensity ultrasound device was investigated as an accelerator of cortical and cancellous bone fracture healing in smokers and nonsmokers. Statistically significant reductions in healing time for smokers and nonsmokers were observed for tibial and distal radius fractures treated with an active ultrasound device compared with a placebo control device.(More)
Records of 25 patients with nonunion of the proximal humerus were reviewed retrospectively. The initial fractures included 19 two-part surgical neck fractures and six three-part fractures. Fourteen fractures were treated nonoperatively and 11 surgically. Nine of 11 of the initial internal fixations were unsatisfactory. At the time of fracture 16 patients(More)
The sacral spine has received relatively little attention in the orthopedic and neurosurgical literature, in part because of the infrequency of developmental, degenerative, or neoplastic conditions of the sacrum requiring surgical intervention. This neglect is unwarranted in trauma, however, because sacral fracture and its associated neural deficit are both(More)
Molecular mechanisms underlying the interaction between malarial sporozoites and putative receptor(s) on the salivary glands of Anopheles gambiae remain largely unknown. In previous studies, a salivary gland protein of ~100 kDa was identified as a putative target based on recognition of the protein by a monoclonal antibody (mAb) 2A3 that caused a >/= 70%(More)
Use of the powered log splitter in processing wood for fuel has emerged as an important source of disabling hand injury in the Vermont area. Thirteen such injuries are reviewed and two representative cases are presented. Physicians are advised of this new mechanism of injury and the public is warned of the danger in using these machines.
A retrospective study of 18 operatively treated calcaneal fractures was conducted. The fractures were all type II and type III fractures according to the classification system of Crosby et al. The average follow-up was 32 months and consisted of subjective and objective criteria. The findings were compared with the results of nonoperative treatment reported(More)
