INTRODUCTION. Vibrotactile feedback has been shown to improve performance in manual control, teleoperation and during minimally invasive surgical tasks. Stochastic resonance (SR), introduced into the human control system as white noise at a sub-sensory level, has shown promise to improve the sensitivity of somatosensory receptors resulting in enhancement of performance for a variety of manual tracking and compliance differentiation tasks. The purpose of this study was to determine if vibrotactil
INTRODUCTION: The ideal treatment of short bowel syndrome remains to be determined. Indicated in severe forms, intestinal transplantation is associated with a 5-years survival rate of only 50%. Parenteral nutrition for life, the most utilized alternative has similar results. We have already used aloogenic arterial segments to replace the upper airway in sheep. The results were encouraging with a transformation of the aortic wall into tracheo-bronchial tissue. In this study, We evaluated the resu
INTRODUCTION- Bacterial overgrowth is common complication of short bowel syndrome (SBS) and is a result of an impaired gut barrier function.Toll-like receptor 4 (TLR-4) is crucial in maintaining intestinal epithelial homeostasis, participates in a vigorous signaling process and heightens inflammatory cytokine output.The objective of this study was to determine the effects of bowel resection on TLR-4 signaling in intestinal mucosa in a rat model.
METHODS AND PROCEDURES- Male Sprague-Dawley rats
Hypothesis:
Surgical meshes made from modified polypropylene (PP) are used in a variety of procedures. Polypropylene mesh undergoes structural changes in the human body that alter its physical properties and contribute to post-operative complications. Oxidative degradation by reactive oxygen species (ROS) from the human inflammatory process may initiate cross-linking, depolymerization, and formation of a more quasi-crystallline quality. Stress cracking and fiber changes cause PP meshes to
Introduction
The incidence of Bile Duct Injuries (BDI) after laparoscopic cholecystectomy, which is a life threatening condition that has several medical and legal implications, currently stands at about 0.6%.
The aim of this study is to describe our experience as one of the first centers to use a laparoscopic approach for BDI repair.
Materials and Methods
A prospective study between June 2012 and September 2014 was developed. Twenty-nine patients with BDI secondary to cholecystectomy
