To better understand the critical conversions that RNA polymerase II complexes undergo during promoter escape, we determined in vitro the precise positions of the rate-limiting step and the last step requiring negative superhelicity or TFIIE and TFIIH. We found that both steps occur after synthesis of an 8 nt RNA during the stage encompassing translocation(More)
Sacral fractures are commonly associated with pelvic ring fractures due to high-energy mechanisms of injury. An understanding of the anatomic relation of the sacrum to the lumbar spine, pelvis, and surrounding neurovascular structures is critical in evaluating functional deficits that may be associated with sacral fractures. While displaced fractures can be(More)
In order to identify the predictive value of synovial fluid white blood cell (WBC) count and differential white blood cell count in identifying nonprosthetic joint infection in immunocompetent and immunosuppressed populations, we retrospectively reviewed 96 adult patients who underwent hip or knee aspiration because of symptoms suggesting a possible(More)
BACKGROUND Very limited information exists about factors affecting direct clinical costs of rotator cuff repair surgery. The purpose of this study was to determine the direct cost of outpatient arthroscopic rotator cuff repair surgery using a unique value-driven outcomes tool and to identify patient- and treatment-related variables affecting cost. METHODS(More)
