introduction the materials used for obturation of root canal system may be extruded through apical foramen into the periapical tissue. therefore, biocompatibility of these materials is very important. the purpose of this study was to evaluate the in vivo biocompatibility of three conventional endodontic sealers: ah26, roth 801, and zoe after their subcutaneous implantation in rats. methods twen...

PURPOSE To evaluate the influence of sepsis in the process of wound healing in the abdominal wall. METHODS 40 rats divided into two groups of twenty animals: group of study (E) - septic, and the control group (C) - not septic. The two groups were divided into subgroups of 10 to be killed on the third day (n = 10) or seventh (n = 10) postoperative. Sepsis was induced by ligation and puncture o...

Based on concentration probability of estimators about a true parameter, third-order asymptotic e ciency of the rst-order bias-adjusted MLE within the class of rst-order bias-adjusted estimators has been well established in a variety of probability models. In this paper we consider the class of second-order bias-adjusted Fisher consistent estimators of a structural parameter vector on the basis...

For several years, Jordan has been working in building and improving its e-government infra structure. As a result, there have been some improvements in the position of Jordan e-government relative to the worlds’ egovernments (according to some reports). However, some metrics and statistics about the online users do not indicate that there is a large percent of Jordanian citizens who are using ...

The clinical management of meningitis caused by Escherichia coli is greatly complicated when the organism becomes resistant to broad-spectrum antibiotics. We sought to characterize the antimicrobial susceptibilities, sequence types (ST), and presence of known drug resistance genes of E. coli isolates that caused meningitis between 1996 and 2011 in Salvador, Brazil. We then compared these findin...

this investigation aimed to examine the protective function of vitamin e on rat bone marrow mesenchymal stem cells (mscs) treated with cadmium chloride. rat bone marrow mscs were extracted using flashing-out and cultured in dmem containing 10% fbs and 100 u/ml pen/strep. at the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...

in the 1960's noboru iwahori and hideya matsumoto, eiichi abe and kazuo suzuki, and michael stein discovered that chevalley groups $g=g(phi,r)$ over a semilocal ring admit remarkable gauss decomposition $g=tuu^-u$, where $t=t(phi,r)$ is a split maximal torus, whereas $u=u(phi,r)$ and $u^-=u^-(phi,r)$ are unipotent radicals of two opposite borel subgroups $b=b(phi,r)$ and $b^-=b^-(phi,r)$ contai...
