AIM To report the authors' experience with the use of opaque intraocular lenses (IOL) in diplopia unresponsive to traditional management strategies, and to assess patients' satisfaction and the visual function of patients following insertion of opaque IOL using the Visual Function Index (VF-14). SETTINGS Royal Victoria Infirmary, Newcastle upon Tyne, UK. METHOD Data were obtained on all pat...

BACKGROUNDS With respect to the knife's design in colorectal endoscopic submucosal dissection (ESD), diameter, water jet function, and electric power are important because these relate to efficient dissection. In this study, we analyzed a novel, narrow ball tip-typed ESD knife with water jet function (Flush knife BT-S, diameter: 2.2 mm, length: 2000 mm, Fujifilm Co., Tokyo, Japan) compared to a...

A new abstract model of interaction between agents and environments considered as objects of diierent types is introduced. Agents are represented by means of labelled transition systems considered up to bisimilarity. The equivalence of agents is characterised in terms of an algebra of behaviours which is a continuous algebra with approximation and two operations: nondeterministic choice and pre...

background: various studies are seeking to find new methods to improve techniques of laryngeal mask airway (lma) insertion and reduce possible complications. in this study, we embarked on a clinical study to investigate the advantages of a new insertion method of laryngeal mask and to compare it with the classic method. materials and methods: two hundred patients aged 20-60 years old in 2012 we...

purpose: according to frequent needs to gastric decompression by nasogastric tube insertion during laparoscopic cholecystectomy, the current comparative study was accomplished through single blind clinical trial considering both the presence and the absence of guide wire insertion. materials and methods: twenty patients were selected for elective surgery of laparoscopic cholecystectomywith gene...

Background: Robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations.Objective: In this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diagram. Non-homogenous camel liver can be exploite...

Background: Intra uterine devices (IUDs) are among the most commonly used contraception methods around the world. The most common form of IUDs used in Iran, is IUD Copper T-380A. As recently there is great emphasis on the role of blood zinc levels on general health conditions, this study was performed to assess the effects of IUD T-380-A insertion on zinc and also copper serum levels. Materials...
