metabolic syndrome is a chronic low-grade inflammation condition which is associated with central obesity, dyslipidemia, insulin resistance and hypertension. inflammation in metabolic syndrome is not only associated with elevated serum inflammatory markers, such as c-reactive protein (crp), but also, is associated with low-grade inflammation in adipose tissue and releasing of adipokines. higher...
introduction: diode laser with wavelengths ranging from 810 to 980 nm in a continuous or pulsed mode was used as a possible instrument for soft tissue surgery in the oral cavity. discussion: diode laser is one of laser systems in which photons are produced by electric current with wavelengths of 810, 940 and 980nm. the application of diode laser in soft tissue oral surgery has been evaluated fr...
background neck reconstruction is considered as one of the most important surgeries in cosmetic and reconstructive surgery. the present study aimed to assess the results of reconstructive surgery of extensive face and neck burning scars using tissue expanders. methods this descriptive prospective study was conducted on 36 patients with extensive burning scars on the neck and face. operation for...
objective: the aim of this study was to evaluate the effect of sucrose on follicular survival rate and the incidence of apoptosis in rat ovarian tissue following vitrification. methods: ovaries of approximately 5-week-old female wistar rats were divided randomly into three groups: control (non-vitrified), vi (ethylene glycol + dimethyl sulfoxide) and vii (eg + dmso + 0.25 mol/lit sucrose). vit...
مقدمه و هدف: مطالعات اندکی در کشورهای غرب آسیا در مورد شیوع بیماری سلیاک صورت گرفته است و در ایران تنها یک مطالعه به بررسی شیوع بیماری سلیاک در اهداء کنندگان خون پرداخته است. هدف این مطالعه بررسی شیوع بیماری سلیاک در شهر ساری است. مواد و روش ها: این مطالعه توصیفی در سال 1382 روی 1438 نفر (686 مرد و 752 زن، متوسط سن 35.5 سال از محدود سنی 18-66 سال) افراد اهل شهر ساری به روش تصادفی لایه ای انجام ...
biological behavior study of gelatin coated pcl nanofiberous electrospun scaffolds using fibroblasts
scaffold design has pivotal role in tissue engineering. in the present study, we modified the surface of electrospun poly(caprolactone) (pcl) nanofibers to improve their compatibility with living medium and to show the potential application of pcl nanofibers as a artificial extracellular matrix using in tissue-engineering. pcl nanofibers were fabricated by electrospinning method. to graft gelat...
background: autoregulation of blood flow is a marvelous phenomenon balanc- ing blood supply and tissue demand. although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. the biomechanical aspect provides insights to us to model vessel diameter changes more precisely and comp...
Introduction: Cigarette smoking has been recognized to be a risk factor for progression of periodontal disease . Due to less inflammation and bleeding in the presence of clinical signs of periodontal disease in smokers than in nonsmokers and given the conflicting results of studies on changes in the epithelium and gingival connective tissue by smoking, this study was performed to evaluate the t...
Background and Aim: One of the most common metabolic diseases is diabetes with hyperglycemic properties and endogenous insulin dysfunction. This study aimed to evaluate the effect of 10 weeks HIIT on HIF-1α gene expression in heart tissue of rats with type 2 diabetes. Methods: In this experimental study, 36 Wister rats with a mean weight of 200±58g were randomly assigned to control, diabetic,...
background cleft palate (cp) is a common congenital defect. it makes serious difficulties for cleft-affected children. the gold standard of care is autogenous bone grafting which may cause additional problems in donor site along with disappointing results. tissue engineering is a promising solution for a widespread range of defects and disorders. it is reasonable to utilize this novel technolog...
