Wetland ecotourism is one of the main branches of the tourism industry that can play an important role in revitalizing villages, creating jobs and increasing income for villagers, protecting natural, historical and cultural heritage. Accordingly, the present study was conducted from 2018 to 2019 to identify the components affecting the local communities’ participation to develop the ecotourism ...
Mutant K-RAS Promotes Invasion and Metastasis in Pancreatic Cancer Through GTPase Signaling Pathways
Pancreatic ductal adenocarcinoma is one of the most aggressive malignancies, characterized by the local invasion into surrounding tissues and early metastasis to distant organs. Oncogenic mutations of the K-RAS gene occur in more than 90% of human pancreatic cancers. The goal of this study was to investigate the functional significance and downstream effectors of mutant K-RAS oncogene in the pa...
Experimental and clinical studies impressively demonstrate that angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) significantly reduce proteinuria and retard progression of glomerular disease. The underlying intraglomerular mechanisms are not yet fully elucidated. As podocyte injury constitutes a critical step in the pathogenesis of glomerular proteinuria, ...
The renin-angiotensin system (RAS) is a hormone system that has been classically known as a blood pressure regulator but is becoming well recognized as a proinflammatory mediator. In many diverse tissues, RAS pathway elements are also produced intrinsically, making it possible for tissues to respond more dynamically to systemic or local cues. While RAS is important for controlling normal inflam...

The current study sought to compare the rhetorical moves and steps that native-English-speaking Iranian authors of research articles (RAs) employ in writing up ‘discussion’ sections their RAs. It was hypothesized latter group is not as proficient RA discussions former group. A total 66 (N=66) from three reputable international academic journals were sampled years 2009 2019. This corpus then ana...
The use of mesenchymal stem cell (MSC) transplantation for ischemic heart disease has been reported for several years. The main mechanisms responsible for the efficacy of this technique include the differentiation of MSCs into cardiomyocytes and endothelial cells, as well as paracrine effects. However, the differentiation rates of MSCs are very low, and the differentiated cells are not mature. ...
K-ras is an oncogenic GTPase responsible for at least 15-25% of all non-small cell lung cancer cases worldwide. Lung cancer of both types is increasing with an alarming rate due to smoking habits in Malaysia among men and women. Natural products always offer alternate treatment therapies that are safe and effective. Typhonium flagelliforme or Keladi Tikus is a local plant known to possess antic...
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...
