INTRODUCTION A de-functioning loop ileostomy (LI) reduces the consequences of anastomotic leak following low anterior resection, but its construction as well as its closure can be associated with complications. The aim of the present study was to identify risk factors for postoperative complications and particularly to determine if operation performed by trainees carry a higher risk of complica...

Characterization of the length dependence of end-to-end loop-closure kinetics in unfolded polypeptide chains provides an understanding of early steps in protein folding. Here, loop-closure in poly-glycine-serine peptides is investigated by combining single-molecule fluorescence spectroscopy with molecular dynamics simulation. For chains containing more than 10 peptide bonds loop-closing rate co...

OBJECTIVE The standard transcatheter ventricular septal defects (VSD) closure procedure is established with arteriovenous (AV) loop and is called as antegrade approach. The directly retrograde transarterial VSD closure without using AV loop might be better option as shortens the procedure time and decreases radiation exposure. METHODS Our series consist of twelve sequential adult cases with c...

INTRODUCTION The objective of this study is to assess whether the results of loop ileostomy closure in terms of morbidity and hospital stay are influenced by the type of anastomosis and suture used. METHOD All patients who underwent loop ileostomy closure were reviewed. A retrospective cohort study comparing morbidity and hospital stay according to the type of anastomosis (TT/LL) and the type...

Abstract Objective To evaluate the morbidity and mortality related to surgical procedure of loop ileostomy closure, in a reference service coloproctology, as well possible variables that may be higher frequency complications. Methods A retrospective study evaluated 66 procedures performed between December 2005 2017, at coloproctology Barão de Lucena Hospital, Recife, Brazil. Results There were ...

The conformational space of a flexible molecular loop includes the set of conformations fulfilling the geometric loop-closure constraints and its energy landscape can be seen as a scalar field defined on this implicit set. Higher-dimensional continuation tools, recently developed in dynamical systems and also applied to robotics, provide efficient algorithms to trace out implicitly defined sets...

We propose a class hierarchy for loops in a loop nest. Its purpose is to help identify the proper code generation methods for a space-time mapped nest. We illustrate the hierarchy and its use on a loop nest for computing the reeexive transitive closure of a graph.

Aim. Loop ileostomy has high complication rates and causes much patient inconvenience. This study was performed to compare the outcome of tube versus loop ileostomy in management of ileal perforations. Patients and Methods. From July 2008 to July 2011, all patients with ileal perforation on laparotomy where a defunctioning proximal protective loop ileostomy was considered advisable were chosen ...

In robot odometry and SLAM applications the real trajectory is estimated incrementally. This produces an accumulation of errors which gives raise to a drift in the trajectory. When revisiting a previous position this drift becomes observable and thus it can be corrected by applying loop closing techniques. Ultimately a loop closing process leads to an optimisation problem where new constraints ...
