The aim of this study was to investigate changes in immunoreactivity of Ras and Raf-1 in lung epithelial cells of rats exposed to carcinogen NNK after swimming training. 50 Wistar rats were randomly divided into five groups: control, training, training + NNK, NNK and sham. NNK-induced groups received NNK Subcutaneously once a week at a dose of 12/5 mg per kg body weight for 12 weeks. The exerci...
Mental Health and Oral Health-Related Quality of Life in Patients with Recurrent Aphthous Stomatitis
Background and purpose: Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal diseases. The etiology of RAS is unknown, however, some factors are considered to be involved in its occurrence, including genetic factors, trauma, menstruation, stress, anxiety, etc. Mental disorders such as stress and anxiety play a key role in the onset and recurrence of RAS lesions. The purpo...
Peer reviewing is a widely accepted mechanism for assessing the quality of submitted articles to scientific conferences or journals. Conference management systems (CMS) are used by conference organizers to invite appropriate reviewers and assign them to submitted papers. Typical CMS rely on paper bids entered by the reviewers and apply simple matching algorithms to compute the paper assignment....
Background and objectives: Recurrent aphthous stomatitis (RAS) is a painful ulcerative lesion and its incidence is 20% in the society. Myrtus communis (myrtex) has been effective in the treatment of RAS. In this study, two different concentrations (2.5% versus 5%) of myrtex extract were evaluated to discover the most effective concentration for the treatment of RAS. Methods: In this randomized...
Background and Aims: Recurrent aphthous stomatitis (RAS) is the most common oral mucosal inflammatory disease. The frequency of RAS is as much as 20% in the general population. The cause of RAS is not yet fully understood. Antioxidant is a material which has ability to preserve molecules from damage and also can delay the start of it. The aim of this study was to compare saliva level of total a...
Background and purpose: Metadiscourse markers (MDMs) play a significant role in academic witting. They act as a bridge between writers and readers and make a text more understandable. Therefore, this study aimed at investigating the use of MDMs in introduction, methods, results, and discussion (IMRaD) sections of English medical research articles (RAs) published in Iranian and American ISI jour...
Background: The relationship between Coronary Artery Disease (CAD) and the prevalence of Renal Artery Stenosis (RAS) has been demonstrated. Despite high incidence of heart diseases and high frequency of CAD risk factors among Iranian population, this relation has not been clearly determined. This study estimated the prevalence of RAS and its determinants in Iranian angiographic candidates. We a...
The effects of selective phosphoinositide 3-kinase (PI3K) and AKT inhibitors were compared in human tumor cell lines in which the pathway is dysregulated. Both caused inhibition of AKT, relief of feedback inhibition of receptor tyrosine kinases, and growth arrest. However, only the PI3K inhibitors caused rapid induction of cell death. In seeking a mechanism for this phenomenon, we found that PI...
BACKGROUND AND AIM: Recurrent aphthous stomatitis (RAS) is a lesion of the oral cavity with an unknown etiology. Several studies have been performed on the role of tumor necrosis factor-alpha (TNF-α) in RAS. The main purpose of this paper was to review TNF-α level and its gene polymorphism in patients with RAS, the factors influencing the production of TNF-α, a...
