THE REFLECTION OF WATER RESOURCE MANAGEMENT POLICIES IN THE NEWS: A CRITICAL DISCOURSE ANALYSIS

Abstract. This study was mainly concerned with corpus analysis of the news gathered from Tehran Times, an international English newspaper of Iran, in 2017 regarding the officials commenting in water resource management issues in Iran. A corpus of 15 (above 3000 words) news pieces selected according to the content and topic was analyzed. The news were classified under officials' concern, their criticism the past and current plans and calling for attention, and their hopelessness. All in all, the news show a dark hopeless future of water resource in Iran.Keyword: News value, water resource, ideology, discourse analysis

An Investigation of Epistemological Markers in Socio-political Forums on Iranian TV Channels from a Critical Discourse Analysis Perspective

The present article examines epistemological markers in socio-political forums on Iranian TV channels from the critical discourse analysis point of view based on Hyland (2005) and Fairclough (2001).  In this study, 20 selected socio-political panels of 1,2, 3 & 4 channels have been selected, which are samples have been analyzed in qualitatively and quantitatively way in the form of all of them using targeted sampling. The variables studied in this study to be determined by this factors, the gender of the experts, using the live or recorded programs, the number of experts in each program, whether the experts are academic or non-academic. The distribution of epistemological elements in live and recorded programs and the presence of male and female critics and the presence of academic and non-academic factors is different?  Also the distribution of elements in the recorded political and social panels is different with the presence of one or more critics? How the differences between the distributions of elements justified are based on Fairclough discourse analysis model? The results showed that the distribution of hedges, boosters, Attitude markers in the programs of socio-political panels in the Islamic Republic of Iran Broadcasting based on the gender of experts, alive or recorded programs, academic or non-academic experts or the presence of one or more experts in each programs are different. Also, based on discourse analysis patterns, can be justified type of using of epistemological tools in the discourse of experts

Anti-inflammatory and tissue repair effect of cinnamaldehyde and nano cinnamaldehyde on gingival fibroblasts and macrophages

Abstract Background Recurrent aphthous stomatitis has a complex and inflammatory origin. Among the great variety of medications it is increasingly common to use herbal medicines due to the adverse side effects of chemical medications. Considering the anti-inflammatory properties of cinnamaldehyde and the lack of studies related to the effectiveness of its nano form; This study investigates the effect of cinnamaldehyde and nano cinnamaldehyde on the healing rate of recurrent aphthous stomatitis lesions. Methods In a laboratory experiment, cinnamaldehyde was converted into niosomal nanoparticles. The niosome vesicles diameter and polydispersity index were measured at 25°C using a dynamic light scattering (DLS) Mastersizer 2000 (Malvern Panalytical technologies: UK) and Zetasizer Nano ZS system (Malvern Instruments Worcestershire: UK). After characterizing these particles, the (2,3-Bis-(2-Methoxy-4-Nitro-5-Sulfophenyl)-2H-Tetrazolium-5-Carboxanilide) [XTT] assay was used to assess the toxicity of cinnamaldehyde and nano cinnamaldehyde on gingival fibroblast (HGF) and macrophage (THP-1) cells. By determining the release of TNF-α, IL-6, and TGF-β cytokines using ELISA kits, the level of tissue repair and anti-inflammatory capabilities of these two substances were evaluated. Results The size and loading rate of the cinnamaldehyde nanoparticles were established after its creation. The optimized nanovesicle exhibited the following characteristics: particle size of 228.75 ± 2.38 nm, PDI of 0.244 ± 0.01, the zeta potential of -10.87 ± 1.09 mV and the drug encapsulation percentage of 66.72 ± 3.93%. PDIs range was between 0.242–0.274. The zeta potential values at 25°C were from -2.67 to -12.9 mV. The results of the XTT test demonstrated that nano cinnamaldehyde exhibited dose-dependent toxicity effects. Moreover, nano cinnamaldehyde released more TGF-β and had better reparative effects when taken at lower concentrations than cinnamaldehyde. Conclusion Nano cinnamaldehyde and cinnamaldehyde are effective in repairing tissue when used in non-toxic amounts. After confirmation in animal models, it is envisaged that these substances can be utilized to treat recurrent aphthous stomatitis
