This study redescribes an arthroscopic bridge technique for repair of avulsion of the posterior cruciate ligament. The procedure is performed step-to-step. In this technique we created two bone tunnels in the anterior aspect of the tibia and inferior medial of the tibia tuberosity and then create suture fixation of the fragment using the suture bridge. The arthroscopic bridge technique was used...

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)...

aim: benefits of skin-to-skin contact (ssc) between mother and her newborn, specifically when it is conducted immediately after birth, have been recognized for more than 40 years. to determine why ssc is not conducted, the present study considers the opinions of the labor working midwifes about the reinforcing factors in ssc immediately after birth in tehran's hospitals in 2012-2013. methods: i...

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...

For the study of the reparation of the skin and its modifications under the influence of certain substances, it became necessary to develop a method permitting observation of the cicatrization in a medium of known composition. Last October, Carrel and Burrows cultivated in vitro in a drop of plasma several fragments of skin of the adult frog. The present work was begun by making experiments of ...

Interconnection is necessary for competition in telephony, but interconnection agreements are difficult to negotiate. With local service competition, entrants usually cannot duplicate the local loop, so interconnection also involves “renting” the incumbent’s local loops. An incumbent may object to being asked to permit use of its infrastructure by its competitors, in order to allow its competit...
