Introduction: Myocardial infarction (MI) is defined pathologically as cardiac muscle cell death due to abnormal blood flow, prolonged coronary artery ischemia, and replacement of cardiac tissue necrosis as a dense fibrotic lesion. Expression of collagen-1 protein levels and fibrosis increase after myocardial infarction in cardiac tissue. The aim of present study was to investigate the effect of...
premixed non-setting calcium hydroxide (caoh 2 ) paste in pressure syringe system is commonly used in root canal therapy. the aim of this paper is to present a case involving an iatrogenic extrusion of the medicament during endodontic treatment and a literature review of similar reports. the present case demonstrates severe tissue necrosis and other deleterious effects following the extrusion o...
Background: Mesenchymal stem cells (MSCs) have been recently received increasing attention for cell-based therapy, especially in regenerative medicine. However, the low survival rate of these cells restricts their therapeutic applications. It is hypothesized that autophagy might play an important role in cellular homeostasis and survival. This study aims to investigate the regenerative potentia...
درمان آلوپسی (ریزش مو) و اسکار (جای زخم) روی سر با چند بافت گستر و به روش زیگزاگ (پازل): یک روش جدید
Background and Objective: Repairing scalp scar and alopecia is a concern of surgeons. Treating it with tissue expander has indicated promising results in recent decades. This study provides a new method of using two tissue expanders simultaneously for tissue over expansion and repairing flaps’ edge with puzzle method. Materials and Methods: This study was conducted on fifteen 5 to 34- year- ol...
Background & Objective: Cyclophosphamide is an antineoplastic drug that has many clinical uses in cancer treatment, but it has toxic effects due to creation of free radicals. In this study, the effects of curcumin" as an antioxidant drug” on liver tissue was investigated. Materials & methods: 50 wistar adult male rats were selected randomly and were divided in to five groups including co...
Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...
Background: The therapeutic potential of honey is related to antioxidant activity against reactive oxygen species because it contains compounds such as polyphenols; therefore, we evaluated the potential protective effect of honey on subacute toxicity of ACR by histopathologic study on tissue lesions in rat. Methods: In Ferdowsi University of Mashhad, Mashhad, Iran, 2016, male Wistar rats were ...
in this study, cadmium (cd) accumulation was studied in an experimental aquatic exposure. mosquitofish (gambusia affinis) were acutely exposed for 96 h to a high concentration of cd (12 mg/l) and were chronically exposed to a low concentration of cd(0.4 mg/l) for 30 days. cd accumulation profiles differed between the two cd exposures. the cd concentation in g. affinis tissues increased linearly...
The aim of this study was to investigate the therapeutic effects of propolis for the toxicity of cypermethrin (CYP) on histopathological changes in tissues of rainbow trout (Oncorhynchus mykiss). CYP is one of the most toxic pyrethroids highly for the aquatic organisms. The fish were exposed to three sublethal concentrations of CYP (0.0041, 0.0082 and 0.0123 ppm). In addition, different concent...
