recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

background: recurrent aphthous stomatitis (ras) is the most common inflammatory ulcerative condition of oral cavity. the aim of this study was to compare the levels of the salivary malondialdehyde (mda) and total antioxidant capacity (tac) and blood parameter in ras versus healthy controls. methods: this case-control study consisted of 28 patients with ras and 28 age and sex -matched control wi...

background: endometrial cancer is the most common gynecologic malignancy that has often proceeded by a premalignant phase. modern molecular and immune staining methods for precancerous lesions diagnosis have been expanded. one of the genetic alternations in the endometrial cancer carcinogenesis is the mutational activation of the k-ras oncogene. k-ras mutation has recognized to occur at an earl...

colorectal cancer (crc) is one of the most common cancers worldwide. understanding of the tumor behavior, in a much closer look, at the molecular level, results in a more effective treatment and accurate prognosis of the disease. from among various genes altered in colorectal cancer k-ras is assumed to be of diagnostic and prognostic significance. k-ras mutations are believed to be a critical e...

Background: Recurrent aphthous stomatitis (RAS) is a common disease, which several etiologic factors have been considered for it. The infectious agents and immunological factors are the most suspected causes. Recently a few studies with varied results have been done to clarify the role of Helicobacter Pylori (H.pylori) in etiology of RAS. Objective: To find correlations between serum IgG and Ig...

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 ...
