Introduction: Expression of p53 gene is one of the common findings in premalignancies and malignancies of the oral cavity. The aim of the study was to know whether P53 protein is overexpressed in histological sections of oral submucous fibrosis, oral leukoplakia and oral squamous cell carcinoma. The aim of the present study was to determine the overexpression of P53 protein in histological sect...
just as motivation is important in sla research, demotivation constitutes an important factor, too. there are many studies done on demotivation and burnout of teachers. many of these studies have been conducted on one or two aspects of english instruction. consequently, there are few studies which have been done on more than two aspects of english teaching. the aim of this study is to find out ...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
Extract of Anacyclus Pyrethrum contains materials which the potential to affect the tissues of the testis. The aim of the present study was to identify the histological effects of aqueous extract of AP on Rat testis. In this experimental study 48 adult male Wister rats were chosen and divided into experimental (36 rats) and control (12 rats) groups. The rats in the experimental group were divid...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
micro-leakage, one of the major reasons for recurrent decays, may lead to uncontrollable flow of liquids, pulp inflammation and peri-apical pathology. the purpose of this in vitro study was to evaluate micro-leakage of pit and fissure sealants after using three different pit and fissure preparation techniques: 1) acid etching, 2) fissure enameloplasty and acid etching, and 3) air abrasion and a...
the effects of pentoxifylline on the wound healing process in a rat experimental pressure sore model
introduction: the present study used a histological evaluation method to examine the effects of pentoxifylline (ptx) on healing an experimentally-induced pressure sore in a rat model. materials and methods: there were 36 adult male rats used in this study. under general anesthesia and sterile conditions, we used forceps to create one pressure sore on each rat. a double layer of folded skin from...
