this paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

a b s t r a c tintroduction: peripheral nerve injury is a common disorder and leads to permanent neurological defects. schwann cells have been shown to have nerve repair after being transplanted in peripheral nerve injury. the aim of this study was to determine the beneficial effect of allograft schwann cells on electrophysiological outcome after transection of the sciatic nerve in rats.methods...

Introduction: Transplantation of bone marrow stromal cells (BMSCs) or Schwann cells (SCs) can increase axonal regeneration in peripheral nerve injuries. Based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury . We pursued to evaluate the effects of BMSCs and SCs co-transplant...

purpose : to report a case of retained silicone tube case report : we report a case of 48-year-old iranian lady who referred to the department of otolaryngology with 18 years history of epiphora and intermittent mucopurulant discharge from the left lacrimal canaliculi. she had external dacryocystorhinostomy (dcr) with silicon stenting for epiphora 18 years ago but epiphora had continued after s...

OBJECTIVES To laparoscopically compare the effectiveness of 2 cooling devices for renal hypothermia and investigate the feasibility of laparoscopic orthotopic kidney transplant using a pig model. MATERIALS AND METHODS Eight pigs were divided into 2 groups of 4 animals each. Laparoscopic nephrectomy and autotransplant were performed first on only the right kidney. One week later, these procedu...

The urinary excretion of silicon in the rat was found to be enhanced beyond normal levels by the administration of various chemical forms of silicon. The excretion was enhanced to a much greater degree by the administration of ethyl silicate than by magnesium trisilicate, sodium metasilicate, or water glass. The tolerance level of rats to sustained daily doses of ethyl silicate fed via stomach ...
