Stapled End-To-Side Ileocolic Anastomosis in Crohn's Disease: Old Dog, Reliable Tricks? A Retrospective Two-Center Cohort Study.

Objective: Analyze our long-term experience with a less-popularized but stalwart approach, the stapled end-to-side ileocolic anastomosis.

Background: The choice of technical approach to ileocolic anastomosis after ileocecal resection for Crohn's disease affects surgical outcomes and recurrence. Yet, despite heterogeneous data from different anastomotic configurations, there remains no clear guidance as to the optimal technique.

Management, Functional Outcomes, and Quality of Life After Development of Pelvic Sepsis in Patients Undergoing Re-Do Ileal Pouch Anal Anastomosis.

Background: The data on management and outcomes of pelvic sepsis after re-do IPAA are scarce.

Objective: The aim of this study is to report our management algorithm of pelvic sepsis in the setting of re-do IPAA and compare functional outcomes and quality of life after successful management of pelvic sepsis with a no sepsis control group.

Design: This is a retrospective cohort study.

Dietary Saturated Fat Promotes Development of Hepatic Inflammation Through Toll-Like Receptor 4 in Mice.

Nonalcoholic steatohepatitis (NASH) is currently the third most common cause of end stage liver disease necessitating transplantation. The question remains how inflammation and NASH develop in the setting of nonalcoholic fatty liver disease (NAFLD) and steatosis. Understand the roles of toll-like receptor 4 (TLR4) and dietary fats in the development of hepatic inflammation.

Development of steatohepatitis in Ob/Ob mice is dependent on Toll-like receptor 4.

Background And Aim: The etiology of non-alcoholic fatty liver disease (NAFLD) progression, and why some patients develop non-alcoholic steatohepatitis (NASH) vs. uncomplicated NAFLD, is not well understood. Obesity and NAFLD are thought to be associated with high circulating levels of leptin; however, the role of leptin in NASH has been controversial.

Intereukin-10 and Kupffer cells protect steatotic mice livers from ischemia-reperfusion injury.

Steatotic livers are more sensitive to ischemia/reperfusion (I/R) and are thus routinely rejected for transplantation because of their increased rate of primary nonfunction (PNF). Lean livers have less I/R-induced damage and inflammation due to Kupffer cells (KC), which are protective after total, warm, hepatic I/R with associated bowel congestion. This protection has been linked to KC-dependent expression of the potent anti-inflammatory cytokine interleukin-10 (IL-10).

Adenovirus-mediated eNOS expression augments liver injury after ischemia/reperfusion in mice.

Hepatic ischemia/reperfusion (l/R) injury continues to be a critical problem. The role of nitric oxide in liver I/R injury is still controversial. This study examines the effect of endothelial nitric oxide synthase (eNOS) over-expression on hepatic function following I/R.

Mitochondrial uncoupling protein 2 induces cell cycle arrest and necrotic cell death.

Uncoupling protein 2 (UCP2) is a mitochondrial membrane protein that regulates energy metabolism and reactive oxygen species (ROS) production. We generated mouse carboxy- and amino-terminal green fluorescent protein (GFP)-tagged UCP2 constructs to investigate the effect of UCP2 expression on cell proliferation and viability. UCP2-transfected Hepa 1-6 cells did not show reduced cellular adenosine triphosphate (ATP) but showed increased levels of glutathione.

Efficient method of genotyping ob/ob mice using high resolution melting analysis.

Objective: Direct health care costs of obesity continue to grow throughout the world and research on obesity disease models are on the rise. The ob/ob mouse is a well-characterized model of obesity and associated risk factors. Successful breeding and backcrossing onto different backgrounds are essential to create knockout models.

Cerulenin blockade of fatty acid synthase reverses hepatic steatosis in ob/ob mice.

Fatty liver or hepatic steatosis is a common health problem associated with abnormal liver function and increased susceptibility to ischemia/reperfusion injury. The objective of this study was to investigate the effect of the fatty acid synthase inhibitor cerulenin on hepatic function in steatotic ob/ob mice. Different dosages of cerulenin were administered intraperitoneally to ob/ob mice for 2 to 7 days.

Mitochondrial uncoupling protein-2 deficiency protects steatotic mouse hepatocytes from hypoxia/reoxygenation.

Steatotic livers are sensitive to ischemic events and associated ATP depletion. Hepatocellular necrosis following these events may result from mitochondrial uncoupling protein-2 (UCP2) expression. To test this hypothesis, we developed a model of in vitro steatosis using primary hepatocytes from wild-type (WT) and UCP2 knockout (KO) mice and subjected them to hypoxia/reoxygenation (H/R).
