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...

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.

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 ...

background and aims: recurrent aphthous stomatitis (ras) is one of the most common ulcerative diseases of the oral mucosa. definitive etiology of ras has not been conclusively established. there is no certain treatment for aphthous but some drugs such as steroid are commonly used for treatment of ras. regarding the effect of zinc on healing process of epithelial layer and cell division, in this...

abstract :  reovirus (respiratory enteric orphan virus), a naturally occurring benign human pathogen, has an inherent ability to target transformed and cancerous cells and cause their lysis, while leaving non-transformed cells relatively unaffected.  the efficiency of this innate oncolytic activity of reovirus correlates with expression of the ras oncogene.  cells expressing activated ras and t...

Mestastatic prostate cancer cells (MPCCs) frequently metastasize to bone, which is a “favorite soil” for colonization and proliferation of MPCCs. Prostate cancer bone mestastasis is tightly associated with tumor-induced bone lesions, most commonly caused from the etiological imbalance between osteoblastic bone formation and osteoclastic bone resorption, and from the anti-tumor immune response. ...
