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 ...

The renin-angiotensin system (RAS) has been demonstrated to play a critical role in the initiation and progression of atherosclerosis, thereby contributing to development of cardiovascular diseases. Angiotensin II (Ang II), a major substrate in RAS, stimulates atherosclerosis through various deleterious effects such as endothelial dysfunction, cellular proliferation and inflammation. Recently, ...

The initiation or progression of periodontitis might involve a local renin-angiotensin system (RAS) in periodontal tissue. The aim of this study was to further characterize the local RAS in human and rat periodontal tissues between healthy and periodontally-affected tissue. Components of the RAS were investigated using in vitro, ex vivo and in vivo experiments involving both human and Wistar ra...

BACKGROUND Local renin-angiotensin systems (RAS) have been implicated as playing an important role in vascular remodeling. The relationship of this system to the etiology of cerebral aneurysm was investigated. METHODS AND RESULTS The aneurysmal wall from patients with a ruptured or unruptured cerebral aneurysm and the cortical cerebral artery in control patients with head trauma or a glioma w...

Background and Aim: Stress has been associated with recurrent aphthous stomatitis (RAS). The common treatment of RAS is a topical steroid. This study aimed to investigate the difference of salivary cortisol between RAS patients treated with a topi-cal steroid and those without treatment. Materials and Methods: Thirty-two female patients with RAS participated in this case-control study and were...

There are very few studies about K-ras mutations in colorectal cancer (CRC) from developing countries such as Iran. It is therefore essential to conduct studies to learn about the molecular signature of such tumors, allowing the determination of an appropriate management plan. In the present study, we aimed to determine the frequency and types of K-ras mutations among patients with CRC in Iran....

The study of epistemic modality in research articles (RAs) has been found many papers. However, the investigation abstract section RAs viewed from Systemic Functional Linguistics is rarely conducted, especially mechanical engineering RAs. Therefore, purpose this was to investigate roles A number 50 abstracts were collected Scopus Q-1 journal entitled “International Journal Machine Tools and Man...

Cell transformation is clearly linked to epigenetic changes. However, the role of the histone-modifying enzymes in this process is still poorly understood. In this study, we investigated the contribution of the histone acetyltransferase (HAT) enzymes to Ras-mediated transformation. Our results demonstrated that lysine acetyltransferase 5, also known as Tip60, facilitates histone acetylation of ...
