[ 1 ] - اثر هشت هفته تمرین هوازی پس از پیوند سلول‌های بنیادی مغز استخوان بر سطوح فاکتور رشد اندوتلیال عروقی و دوپامین جسم مخطط موش‌های مدل پارکینسون

هدف از پژوهش حاضر، بررسی اثر هشت هفته تمرین هوازی بر فاکتور رشد اندوتلیال عروقی و دوپامین جسم مخطط در موش‌های پارکینسونی، پس از پیوند سلول‌های بنیادی مغز استخوان بود. بدین‌منظور، 35 موش صحرایی نر هفت هفته‌ای‌ با وزن 300ـ250 گرم‌ به‌صورت تصادفی به گروه‌‌های کنترل سالم، پارکینسونی کنترل، سلول‌درمانی، تمرین و سلول‌درمانی + تمرین تقسیم شدند. برای ایجاد مدل پارکینسونی، تخریب جسم مخطط با تزریق پنج می...

[ 2 ] - تغییر گلیکوزآمینوگلیکان‌ها در بافت مغز رت‌های دیابتی

چکیده مقدمه: دیابت ملیتوس بر متابولیسم اجزای ماتریکس خارج سلولی از جمله گلیگوز آمینوگلیگان‌ها مؤثر است. گرچه این تغییرها امروزه مورد توجه قرار گرفته، ولی تغییر گلیکوزآمینوگلیکان‌ها در بافت مغز رت‌های دیابتی، کمتر بررسی شده است. هدف: بررسی تغییرها گلیکوزآمینوگلیکان‌ها در مغز رت دیابتی. مواد و روش‌ها: در یک مطالعه تجربی، 20 سر رت از نژاد ویستار با وزن حدود 250-200 گرم به طور تصادفی به دو گروه ...

[ 3 ] - Time dependent of epigenetic effect of disulfiram on tumor suppressor gene of RASSF1A in Hela cancer cell line

Introduction: Cervical cancer is the third most common tumor among women. Surgery, radiotherapy, and chemotherapy are common treatments, however high stage tumors have frequently poor prognosis. Nowadays, the epigenetic reversion introduced as an efficient strategy of treatment of cervical cancer. In the process, inhibitors of DNA methyltransferase (DNMT) induce re-expression of tumor suppresso...

[ 4 ] - اثر تعاملی 8 هفته تمرین هوازی پس از تلقیح سلول های بنیادی مغز استخوان در جسم مخطط بر شاخص های رفتاری در موش های مدل پارکینسونی

زمینه و هدف: پارکینسون یک انحطاط پیشرونده دستگاه عصبی است که نورون­های دوپامینرژیک جسم سیاه تخریب و به دنبال آن مقادیر دوپامین در جسم مخطط کاهش می­یابد.تلقیح سلول­های بنیادی و انجام تمرینات ورزشی از جمله راه­های درمانی غیردارویی است که برای درمان این بیماری مورد توجه قرار گرفته است. هدف از پژوهش حاضر، بررسی اثر تعاملی 8 هفته تمرین هوازی پس از تلقیح سلول­های بنیادی مغز استخوان بر شاخص­های رفتاری...

[ 5 ] - An overview of Treatment options for urinary stones

Urolithiasis has become a worldwide problem with the prevalence of the disease increasing over the past few decades. While various treatment modalities have evolved over the years, discrepancies exist regarding the clinical indications and the efficacy of each of these treatment options. In the present review, we aim to review the current treatment modalities for urinary tract stones to provide...

[ 6 ] - Histological changes of kidney in diabetic nephropathy

  Diabetes mellitus is the most common cause of chronic renal disorders and end-stage kidney disease in developed countries. It is the major cause of dialysis and transplantation. Failure in renal function causes wide disorders in the body. Diabetes results in wide range of alterations in the renal tissue. It is believed that early histological changes in diabetic nephropathy are detectabl...

[ 7 ] - Early Renal Histological Changes in Alloxan-Induced Diabetic Rats

Diabetes mellitus is a progressive disease. Most investigators have focused on glomerular changes in diabetic kidney and non-glomerular alterations have been less attended. The present study has been conducted to find early non-glomerular histological changes in diabetic renal tissue. Twenty male Wistar rats weighting 200-250 g were used for the diabetic group. Diabetes mellitus was induced by ...

[ 8 ] - Embryological Aspects of Oocyte In Vitro Maturation

In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author’s experience. In IVM cycles,...

[ 9 ] - The Assessment of Early Glycosaminoglycan Concentration Changes in the Kidney of Diabetic Rats by Critical Electrolyte Concentration Staining

Glycosaminoglycan (GAG) has a pivot role in renal function and homeostasis. Analysis of GAG amount generally serves to determine GAG alteration due to diabetes mellitus. Critical Electrolyte Concentration (CEC) staining can be an efficacy method to study GAG amount changes. Based on an experimental study, 20 male rats were randomly divided equally into two experimental and control groups. Diabe...

[ 10 ] - A Modified Method for Cerebrospinal Fluid Collection in Anesthetized Rat and Evaluation of the Efficacy

Dear editor: We would like to present a modified method for cerebrospinal fluid collection in anesthetized rat. This method is easy and applicable in many laboratories interested by research on cellular and molecular effects of CSF on different pathways.

[ 11 ] - Comparison of skin reaction between MTA (produced in Iran) and CEM in Rabbit

Pathological changes in pulp and periapical tissues are addressed by endodontic treatment. The material used in this treatment must be biocompatible. The aim of this study is to compare the skin reaction of Calcium Enriched Mixture (CEM) and Mineral Trioxide Aggregate (MTA) produced in Iran on rabbit. Sixteen male newzeland albino rabbits weighting 2 kg were used. The animals back hair was sha...
