The high DPAT sensitivity (HDS) and low DPAT sensitivity (LDS) rat lines are the result of selective breeding for differences in the hypothermic response to acute treatment with the 5-HT(1A) receptor agonist 8-hydroxydipropylaminotetralin (8-OHDPAT). The HDS rats exhibit a much greater hypothermic response than do the LDS rats. The present study examined(More)
The irretrievably failed total knee arthroplasty is the primary indication for knee arthrodesis. Because this difficult condition is relatively rare, an intramedullary arthrodesis system was developed which requires minimal surgeon experience for successful use. The new system called the Wichita Fusion Nail was implanted by a single surgeon in 13(More)
Negative pressure intrusion (NPI) is an alternative cementing technique for the tibial baseplate of total knee arthroplasty that uses a suction cannula in the proximal tibia to remove excess fluids and fat before cementing. This technique was compared with standard third-generation positive pressure intrusion (PPI) techniques in an in vitro implantation and(More)
Supracondylar fracture of the femur after total knee arthroplasty has an estimated frequency of 0.6%-2.5% among total knee recipients and presents an extremely difficult problem when encountered. The goal of this study is to determine the most stable method of fixation of these supracondylar fractures among currently available devices. Synthetic composite(More)
UNLABELLED The Wichita Fusion Nail (WFN) is a knee arthrodesis stabilization system that employs compression via an intramedullary rod. It was designed for use in the salvage of the irretrievably failed total knee arthroplasty and other severe knee pathologies. Questionnaires covering the fusion success rate, fusion time, and complication rate were obtained(More)
HDS and LDS rats are the result of selective breeding for differences in the hypothermic effects of the 5-hydroxytryptamine-1A (5-HT1A) agonist 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT); HDS (high DPAT sensitivity) rats exhibit a much greater hypothermic response than do LDS (low DPAT sensitivity) rats. It is possible that this genetically-based(More)
Native polyacrylamide gels of extracellular proteins produced by several Streptomyces isolates grown with suberin were assayed in situ for esterase activity. Two pathogenic isolates of Streptomyces scabies from different geographical regions were found to produce a similar esterase activity that was not produced by nonpathogenic strains. After treatment(More)
