conclusions these findings emphasize the potential clinical benefits of therapeutic procedures such as cardiac resynchronization therapy (crt) or apex-sparing volume-reduction surgery in dcm. a better definition of the role and implications of reverse apical torsion in dcm and its importance and effectiveness in making therapeutic decisions like crt implantation requires further studies. case p...

Abstract Background Advanced testing methodologies and measurement techniques to identify complex deformation failure at high strain rates have drawn increasing attention in recent years. Objective The objective of the current study is development a novel combined tension–torsion split Hopkinson bar (TTHB) conceived generate combination tensile torsional stress waves single loading case, measur...

torsion of the gallbladder is a relatively rare surgical disease which mimics acute cholecystitis' symptoms that usually would not be respondable to medical therapies. the torsion would mostly be diagnosed intra-operatively. cholecystectomy is the treatment of choice. in general in our centre, general surgery department, imam reza hospital, mashhad, iran, since 1986 over 14000 cholecystect...

torsion and infarction of the greater omentum are two rare clinical situations which present as an acute abdomen. nevertheless, knowledge concerning these two problems can help the surgeon in proper diagnosis and treatment. since the first report on primary torsion by eitel in 1899, a few hundred more have been reported and some collective reviews published to date. in this study we will presen...

In this paper, we present the dynamic response of commercially pure copper subjected to combined tension-torsion loads representative real case impact scenarios. Experiments were conducted both quasi statically, at a strain rate equal 10?3 s?1, and dynamically rates in region between 500 s?1 1000 s?1. All high experiments using novel Split Hopkinson Tension-Torsion Bar instrumented with high-sp...

The mechanical characterisation of cables can help improving the production and lifetime various products, for example a robotic arm. Cables however form class composite structures, that is highly anisotropic dissipates energy due to reorientation its constituents which superimposed by dissipation deformation polymer components. also have degree randomness in their structure. Moreover, stiffnes...

Background The aim of this study was to determine oxidative stress (OS) parameters after testicular torsion/detorsion in adult rats. MaterialsAndMethods In this experimental study, male adult Wistar rats were divided into four groups, each consisting of seven animals: group I-one hour right testicular torsion with subsequent orchiectomy, group II-one hour right testicular torsion followed by de...

Manufacturing and Testing techniques were investigated for the development of efficient joining of composite tubes. The stepped lap joining arrangements were studied. Finite element models were developed using ANSYS finite element code for predicting the stress distribution of the joint under the applied loads. Tubes made of graphite/epoxy were considered. The tubes were tested under both tensi...

background: testicular torsion is a medical emergency with catastrophic sequelae that deserves the same treatment considerations and concerted efforts in research as any other complicated medical condition. the aim of this study was to investigate the effect of pausinystalia macroceras (pm) bark extract on sperm quality and serum testosterone levels in testicular torsion in a rat model. methods...
