In order to study the effect of air and root-zone temperature on yield, yield components, nodulation and nitrogen fixation of three annual medics, an experiment was conducted in controlled environment (growth chamber) at the Faculty of Agriculture, Tarbiat Modares University in 2006. The experiment was performed as a spilt split plot with the layout of completely randomized design with three re...

abstract background: distal radial fracture is one of the most common fractures of the skeletal system. although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. the goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extra...
conclusions negative pressure inspiration is significantly impaired by an unstable chest wall. restoring mechanical stability of the fractured ribs improves respiratory outcomes similar to baseline values. results a wide variation in the mean inspiratory volumes and peak flows were measured between specimens; however, the effect of a flail chest wall and the subsequent internal fixation of the ...
Background: Comminuted subtrochanteric fractures have been a challenge for orthopedic surgeons in terms of appropriate reduction and stable fixation. Numerous methods have been used for the fixation of comminuted subtrochanteric fractures among which some are accompanied with technical difficulties and complications of their own. Regarding the results of previous studies, we decided to evaluate...
Background: Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. Purposes: We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compar...
pediatric mandibular fractures have been successfully managed in various ways. the use of a lingual splint is an option. this article presents a 4-year old boy who was treated by an alternative conservative method with a combination of an arch bar plus a lingual splint, circum-mandibular wiring and imf for the reduction, stabilization and fixation of a severely displaced bilateral man dibular b...
Background & Aims: supracondylar humerus fracture is one of the most common pediatric elbow fractures accounting for about 16% of the pediatric fractures. Loss of reduction is one of the complications after closed and percutaneous fixation. This research is aimed to investigate the factors involved in the loss of reduction. Method: In this descriptive study, the children with supracondylar hum...
background: the treatment of open tibial fractures is still an orthopaedic challenge and full of complications. in many cases the use of external fixator that has been known as a non-:union: machine is obligatory with a high incidence of pin track infection and other complications. the aim of this study was to compare the use of external fixation as a definite method for treatment of open tibia...
Background: Respiratory problems are common after long bone fractures. The objective of the present investigation is to evaluate the effect of early fixation of femoral shaft fracture on the incidence of respiratory problems. Methods: The results of early and late stabilization of femoral shaft fractures were studied in 150 patients. The patients were divided into two groups according to the st...
