In studies directed at determining the activities of selected enzymes in lung tissue after in vivo exposure to hyperoxia, 70-day-old rats were exposed to 85% or 90% O2 for 1-14 days. After 7 days of exposure to 90% O2 (1atm), superoxide dismutase activities in mitochondrial and cytosolic fractions increased, respectively, to 245 and 145% of control;(More)
OBJECTIVE Reports describing laparoscopic lymph node sampling in patients with gynecologic malignancies have yet to describe a method to sample left-sided aortic lymph nodes that has been successful in a large series of patients. We submit our experience with evolving techniques that allow for excellent visualization and resection of both left and right(More)
BACKGROUND Expert panels of colorectal surgeons consistently rank anastomotic leak as among the most important quality metrics for colectomies. Nonetheless, most administrative and clinical databases do not collect data on anastomotic leaks and rely on reported organ space surgical site infections (OSI) as a proxy for identifying anastomotic leaks. This(More)
OBJECTIVE The purpose of this study was to incorporate a wide range of operative laparoscopic techniques to complete a type III radical hysterectomy with aortic and pelvic lymphadenectomy. STUDY DESIGN A type III radical hysterectomy with bilateral aortic and pelvic lymph node dissection was separated into eight component parts: (1) right and left aortic(More)
Rats were exposed to 12% O2 (1 atm) for 48 hr, then 10% O2 for the duration of the exposures. Significant elevations in enzymes of the glutathione peroxidase system were found in the lungs of rats killed 3.5, 7.5, and 12.5 days of exposure compared to air-breathing controls. Superoxide dismutase was also elevated after hypoxia but nonsignificantly. Animals(More)
OBJECTIVE This study was undertaken to evaluate the deoxyribonucleic acid content and S-phase fraction in advanced epithelial ovarian carcinomas to determine whether lymph node metastases are biologically distinct from peritoneal sites of metastases. STUDY DESIGN Thirty-five patients with stage III or IV epithelial ovarian cancer who had undergone(More)
