Mta is a cell surface antigen of the mouse and serves as a target for specific T killer lymphocytes. Using a killer cell assay, the antigen has been found in 72 strains of laboratory mice and, with one exception, in all tested samples of mice caught in the wild or bred from such, including Mus molossinus, Mus castaneus and Mus spretus. Five strains of rats, non-inbred NMRI mice, most substrains...
Mineral trioxide aggregate (MTA) has been found to be very biocompatible in a large number of studies. However, the handling properties can be challenging and research on modified materials to enhance placement are few. The purpose of this study is to compare a new faster setting, and more easily placed preparation with classic MTA in an animal model. Canine premolar teeth from two dogs were ra...
سابقه و هدف: تاکنون مواد زیادی جهت پر کردن انتهای ریشه حین جراحی اندودنتیک مورد استفاده قرار گرفته است. خواص مطلوب MTA در مطالعات مختلف in vitro و in vivo ثابت شده است. از سوی دیگر بر اساس مطالعات انجام شدهRoot MTA (MTA ایرانی) و سیمان پرتلند از لحاظ خواص فیزیکی و بیولوژیک مشابه MTA می باشد. هدف از این مطالعه بررسی مقایسه ای تطابق حاشیه ای چهار ماده پر کننده انتهای ریشه ( Root MTA, White Pro ro...
esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
Background and Aim: Several materials have been introduced for retrograde fillings, pulp capping and sealing root perforations, but their biological effect on vital tissues and cells is not clear. The purpose of this study was to evaluate the reaction of human periodontal ligament fibroblasts to four root canal filling materials: Pro Root MTA, Root MTA, Portland cement and amalgam. Materials a...
Background and Aim: The goal of endodontics is to seal the root canal system from the orifice to apical constriction completely and tridimensionally.Hence perforations during root canal therapy, because of caries or resorptions must be sealed and obturated with ideal materials. The aim of this study was to histologically compare two kinds of mineral trioxide aggregate Root MTA and Pro Root MTA ...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
to our findings. The authors further state that " … the same observations were also made for STAT6 (Chen et al., 2004). " Meissner et al. incubated the cells with MTA In their Matters Arising article, Meissner et al. present several experiments that call into question our conclu-in DMSO, whereas we had solubilized MTA in tissue culture media. While somewhat unexpected, this differ-sions from th...
MTA (LY231514) is an antifolate that targets multiple folate-dependent enzymes. In this report, MTA transport was characterized in wild-type L1210 cells and variants with impaired membrane transport or polyglutamation. MTA influx via the reduced folate carrier was somewhat faster (approximately 30%) than that for methotrexate (MTX). Unlike MTX, MTA was rapidly polyglutamated in L1210 cells; hen...
