Abstract The influences of processing parameters and tool feature on the microstructure AA1100 AA3003 aluminium alloys were investigated using bobbin friction stir welding (BFSW). research includes flow visualization microstructural evolution weld texture metallographic measurement method. Results indicated that operational (e.g. feed rate, rotating speed) geometry can directly affect patterns ...
The purpose of this retrospective case control study was to evaluate the results of intrafocal pinning for distal radius metaphyseal fractures in children and to compare these results with conventional pinning. Data were collected from medical records and radiographs from patients who underwent closed reduction and percutaneous pinning for distal radius fracture in a Level I trauma center at th...
BACKGROUND A challenge in prostate cancer (PCa) management is identifying potentially lethal disease at diagnosis. Inflammation, focal prostatic atrophy, and prostatic intraepithelial neoplasia (PIN) are common in prostate tumor specimens, but it is not clear whether these lesions have prognostic significance. METHODS We conducted a case-control study nested in a cohort of men diagnosed with ...

Over 90% of prostate cancers express telomerase activity. In an experimental model, hsp90 and p23, which are necessary for telomerase assembly and function, dramatically increase during tumorigenic conversion. We immunohistochemically analyzed 60 prostate carcinomas, 50 prostatic intraepithelial neoplasias (PIN) and 25 benign prostatic tissues to determine whether hsp90/p23 expression correlate...
