the effect of nerve growth factor (ngf) on regeneration of rat sciatic nerves in adult rat was studied. the sciatic nerve was cut out across a 6‑mm gap, then the proximal and distal stumps were inserted into the silicone tube chamber. 7s ngf was extracted from submaxillary gland and then was injected into the silicone in experimental group. after seven months nerve was transected and stained wi...

background: the aim of this study was to evaluate the impact of diabetes mellitus (dm) on peripheral vascular disease (pvd) in patients with coronary artery disease (cad). methods: a total of 13702 consecutive patients who underwent coronary artery bypass grafting (cabg) at tehran heart center between january 2002 and march 2007 were included in this study. the demographic data, pvd, and outcom...

there are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. wallerian degeneration and chromatolysis are the most conspicuous phenomena that occur in response to injuries. in this research, the effects of post-operative time following sciatic nerve crush on the number of spinal motoneurons were investigated....

background: recognition of helminth-derived pathogen associated molecular patterns (pamps) by pattern recognition receptors (prrs), including toll like recep­tors (tlrs) is the first step towards initiating anti–helminth immune re­sponses. methods : using somatic antigens of ostertagia occidentalis, an important abomasal parasite of ruminants, the expression of ovine tlr2 and tlr4 in peripheral...

background: parasitological methods for the diagnosis of visceral leishmania-sis (vl) require invasive procedures, so serological and molecular approaches have been developed but are not generally applicable in the field. we evaluated a loop mediated isothermal amplification (lamp) assay using blood from vl pa-tients and compared it to nested pcr. methods: forty-seven subjects with clinical fea...

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...

Introduction: Peripheral odontogenic tumors are rare and there is no valid information of the frequency of them in the literature. This study aims to obtain the frequency of these tumors. Materials and Methods: The files of oral and maxillofacial pathology (microscopic reports and slides), faculty of dentistry, Shahid Beheshti University of medical sciences served as the source of the material...

literatures of various cultures interfere with one another so that each of them may become part of another’s literary polysystem. accordingly, the researchers, in this study, attempted to recognize what position persian literary polysystem allowed english literature in particular persian translations of english modern short stories to occupy during 1990-2005. this study also intended to find ou...

conclusions in conclusion, occult hbv was found in 36% of patients with negative results for hbsag, but positive results for hcv. detection of hbv-dna in both pbmcs and plasma together in comparison with plasma alone provided more true identification of obi.the svr rate was significantly higher in coinfected patients than mono-infected ones. background occult hepatitis b virus (hbv) infection (...

background: dendritic cells (dcs) are the most potent stimulators of primary t cell responses and play a key role in immune reactions after stem cell transplantation. very little is known about the cord blood (cb) dendritic cells and their potential involvement in the low incidence and lower severity of acute graft-versus-host disease after cb transplantation.   objectives: the aim of this stud...
