BACKGROUND Biliopancreatic diversion (BPD) is a complex bariatric operation requiring meticulous surveillance which has impeded its broad adoption. Improvements in surgical care and technique, better teaching programs, and stringent norms for follow-up have contributed to increased safety of BPD for patients with BMI <50, achieving better long-term results than other bariatric operations. Here ...

BACKGROUND This study examines 1,791 consecutive laparoscopic adjustable gastric banding (LAGB) procedures with up to 12 years follow-up. Long-term results of LAGB with a high follow-up rate are not common. METHODS Between September 1993 and December 2005, 1,791 consecutive patients (75.1% women, mean age 38.7 years, mean weight 127.7 +/- 24 kg, mean BMI 46.2 +/- 7.7) underwent LAGB by the sa...

CONTEXT About 5% of the US population is morbidly obese. This disease remains largely refractory to diet and drug therapy, but generally responds well to bariatric surgery. OBJECTIVE To determine the impact of bariatric surgery on weight loss, operative mortality outcome, and 4 obesity comorbidities (diabetes, hyperlipidemia, hypertension, and obstructive sleep apnea). DATA SOURCES AND STUD...

Treatment of cultured pancreatic B-cells (HIT-T15 and RINm5F) with the diabetogenic drug streptozotocin resulted in a significant increase in the number of cells that became detached from the substrate during a subsequent culture period. Examination of the detached cells by fluorescence microscopy after staining with acridine orange or by electron microscopy revealed evidence of chromatin conde...
