Use of Barbed Sutures in Laparoscopic Gastrointestinal Single-Layer Sutures
BACKGROUND AND OBJECTIVES Laparoscopic anastomotic methods are not commonly used because of the cumbersome laparoscopic intracorporeal sutures and tying involved. The barbed suture is one of the various devices developed to simplify the placement of intracorporeal sutures. However, barbed sutures are not commonly used during reconstruction after radical gastrectomy in cancer patients or for sin...
متن کاملContact probing of stretched membranes and adhesive interactions: graphene and other two-dimensional materials
Contact probing is the preferable method for studying mechanical properties of thin two-dimensional (2D) materials. These studies are based on analysis of experimental force-displacement curves obtained by loading of a stretched membrane by a probe of an atomic force microscope or a nanoindenter. Both non-adhesive and adhesive contact interactions between such a probe and a 2D membrane are stud...
متن کاملStretched Exponential Kinetics of the Pressure Induced Hydration of Model Lipid Membranes. A Possible Scenario
The kinetics of the pressure induced hydration of modellipid membranes is studied in terms ofthe Avrami-Kolmogorov model and the fractal-like chemical reaction kinetics concept. As a general result, the stretched exponential relaxation function of the
متن کاملNMR study of the anisotropic transport properties of uniaxially stretched membranes for fuel cells
We used NMR techniques to probe the anisotropic properties of stretched Nafion 115 membranes. The alignment of the polymeric structure under a uniaxial load is at the origin of a strong anisotropy of both the water self-diffusion coefficient and the proton conductivity. The determination of these two important membrane properties may lead to new fundamental information on the nature of the pr...
متن کاملThe sutures in dentistry.
In oral surgery, the last phase of a surgical operation is represented by the tissues suture, that allows the wound lips edges approximation and their stabilization, to promote haemostasis, to avoid the alimentary residues accumulation on the incision line and allow the first intention healing. A good suture avoids that the displacing forces generated by the muscular insertions, functional move...
