microbial factors may play a role in the pathogenesis of recurrent aphthous stomatitis (ras). because of similarities in the characteristics of peptic ulcers and oral aphthous ulcers, it seems reasonable to hypothesize that helicobacter pylori ( h. pylori ) could play a role in the development of ras. the aim of the present study was to determine the relationship between h. pylori and ras using...

The complex chemistry of uranyl nitrate with mono and bi-functional neutral extractants shows, that it forms 1:2 and 1:1 complexes respectively. The structures of the isolated complexes show, that the water molecules from the primary coordination sphere of [UO2(NO3)2.2H2O] are replaced by the extractants completely and adopt a hexagonal bi-pyramidal geometry. However, the structural chemistry o...

the present study explored the rhetorical representation of authorial identity signaled by interactive/interactional metadiscourse strategies and integral/non-integral citation patterns in international and iranian local research article discussion sections. the study also explored variation in metadiscourse and citation resources across three subdisciplines of language testing, english languag...

Over the last decades, there has been a plethora of interest in possible challenges encountered by researchers while publishing research articles (RAs) in various disciplines for English for academic purposes (EAP).Given this, this study aimed to examine how a sampled number of EAPIranian researchers perceive the competence of academic RA writing, the major reasons for RA rejection, and difficu...

This article describes a strategy for teaching undergraduate students to read research articles (RAs)—called the hero narrative reading strategy. modifies an existing approach RAs (the Scientific Argumentation Model [SAM]), which teaches identify article’s rhetorical moves. The relabels moves that SAM identifies in RA introductions (Motive and Objective), it frames as narratives; are taught see...

Disciplinary studies on metadiscourse in academic texts have come a rather long way (since the 1980s) to afford an awareness of the ways authors strive to signal their insights into their materials as well as their audience. However, few comprehensive corpus-based studies to date have provided a starting point for shaping our understanding of subdisciplinary and paradigmatic diversities within ...

Background and Aim: Recurrent aphthous stomatitis (RAS) is the most common oral mucosal lesion in the general population. Different treatments have been used for RAS, including herbal medicine. In this study, the randomized clinical trials (RCTs) on the effect of medicinal plants on RAS were systematically searched and reviewed. Materials and Methods: The literature from 1985 to 2015 in the ...
