Long-Term Outcomes of Bariatric Surgery: A Systematic Review.

Roux-en-Y gastric bypass (RYGB) is a minimally invasive procedure that usually takes two hours. It is commonly performed in refractory cases to help morbidly obese patients (BMI ≥ 40 kg/m2) lose weight. It is well known that morbid obesity accompanies other comorbid conditions such as atherosclerotic diseases, strokes, cancers, and mental health issues such as anxiety and depression.

Possible association of diazotrophs with marine zooplankton in the Pacific Ocean.

Dinitrogen fixation, the biological reduction in N gas to ammonia contributes to the supply of new nitrogen in the surface ocean. To understand the diversity and abundance of potentially diazotrophic (N fixing) microorganisms associated with marine zooplankton, especially copepods, the nifH gene was studied using zooplankton samples collected in the Pacific Ocean. In total, 257 nifH sequences were recovered from 23 nifH-positive DNA extracts out of 90 copepod samples.

Acute ischemic gangrene of the rectum: Report of 3 cases and review of literature.

Introduction: Acute ischemia of the rectum resulting in full thickness necrosis is extremely uncommon because of its excellent blood supply.

Presentation Of Case: We present 3 cases with spontaneous ischemic gangrene of the rectum. All three patients were elderly with atherosclerotic arterial disease and presented with hypotensive shock but in none of these patients we encountered a precipitating factor such as preceding vascular surgery or shock state.
