First Application of a Mixed Porcine-Human Repopulated Bioengineered Liver in a Preclinical Model of Post-Resection Liver Failure.

In this study, a mixed porcine-human bioengineered liver (MPH-BEL) was used in a preclinical setup of extracorporeal liver support devices as a treatment for a model of post-resection liver failure (PRLF). The potential for human clinical application is further illustrated by comparing the functional capacity of MPH-BEL grafts as assessed using this porcine PRLF model with fully human (FH-BEL) grafts which were perfused and assessed in vitro. BEL grafts were produced by reseeding liver scaffolds with HUVEC and primary porcine hepatocytes (MPH-BEL) or primary human hepatocytes (FH-BEL).

Early closure compared to late closure of temporary ileostomy in rectal cancer: a randomized controlled trial study.

Background: A temporary loop ileostomy is one of the most common methods for the prevention of anastomotic leakage in rectal cancer patients who underwent low anterior resection. However, the optimal timing of loop ileostomy reversal remains unknown. The main objective of this study was to evaluate the debilitating complications caused by early closure of ileostomy in comparison with late closure in rectal cancer patients.

Pulling Seton: Combination of mechanisms.

Background: Seton-based techniques are among popular methods for treating high type anal fistula. These techniques are categorized to cutting and noncutting regarding their mechanism of action. In this report we are about to describe a new technique, which is a combination of both mechanisms; we call it Pulling Seton.
