OBJECTIVE Ventricular assist devices (VAD) are an important therapy that saves the lives of candidates a waiting heart transplantation (HTx). However, there are questions about posttransplantation effects of VADs. METHODS Seventy-four patients with end-stage heart failure who underwent HTx in our clinic between February 2007 and July 2011 were divided into two groups; a bridge cohort (n = 28)...

Plasmid conjugation systems are composed of two components, the DNA transfer and replication system, or Dtr, and the mating pair formation system, or Mpf. During conjugal transfer an essential factor, called the coupling protein, is thought to interface the Dtr, in the form of the relaxosome, with the Mpf, in the form of the mating bridge. These proteins, such as TraG from the IncP1 plasmid RP4...

introduction: the aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (mta) and 0.2% chlorhexidine (chx) mixture to pure mta, as a pulp capping material. methods and materials: the pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with mta or mta+0.2% chx. after 2 months the animals were sacrificed and the teeth were pre...

An incumbent may object to being asked to permit use of its infrastructure by its competitors, in order to allow its competit...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...

abstract our religious teachings show a bridge on hell that in the hereafter, all will inevitably pass over it. the bridge path is very slippery and difficult to pass and has obstacles that each is called by particular name. peoplepass overit invariousforms. some fall to the depths of hell, some hop or suspend and a group pass quickly and easily.this paper studies and analyzes these teachings b...
