BACKGROUND The purpose of this study was to evaluate the necessity of early postoperative radiographs after pinning of supracondylar humerus fractures by determining both the percentage of patients who displayed change in fracture fixation and whether these changes affected their outcome. METHODS A series of 643 consecutive patients who underwent operative management of Gartland type II and I...

OBJECTIVE This case report describes the novel use of an intramedullary pin in an eight-month-old cat to repair malunion of a right transverse ilial fracture that was causing pelvic canal diameter narrowing and constipation. METHOD A routine, right femoral head and neck ostectomy was performed due to the presence of a femoral head fracture with apparent femoral neck necrosis. Significant call...

prostatic intra-epithelial neoplasia (pin) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. in this study, we applied the pin grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of pro...

Background: Intramedullary pinning (IMP) is the most commonly used internal skeletal fixation technique. Threaded pins (also called Schanz Screws) provide a comparatively better holding strength than non-threaded tipped intramedullary pins. The present study was planned to evaluate and compare efficacy of positive negative profile end threaded in management long bone fractures dogs. Methods: El...

Friction stir lap welding (FSLW) experiment has been conducted on 3mm thick AZ80 extruded sheet and 2.3mm thick AZ31B rolled sheet. The influence of the shape of the taper thread mixing head on microstructure has been discussed. Pores forming, hooked defects, interface migration, tissue distribution have been analyzed. The organization of both sides of nugget zone (NZ) is arranged diagonally ab...

The functional integrity of the intestinal epithelial barrier relies on tight coordination of cell proliferation and migration, with failure to regulate these processes resulting in disease. It is not known whether cell proliferation is sufficient to drive epithelial cell migration during homoeostatic turnover of the epithelium. Nor is it known precisely how villus cell migration is affected wh...

The high pressure turbine nozzle guide vane of a modern aeroengine experiences large heat loads and thus requires both highly effective internal external cooling. This can be accomplished with double-wall effusion cooling, which combines impingement, pin-fin combination three cooling mechanisms causes losses, increasing potential for the migration coolant towards low regions, subsequently starv...
