Abstract The effects of compounds containing oxazoline groups and the presence of maleic anhydridegrafted polypropylene (PP-g-MAH) on the spectral, morphological, and tensile properties of polypropylene (PP)/liquid crystalline polymer (LCP) blends were investigated. A wholly aromatic LCP having a low melting point which was copolyester, namely AL-7000 have been used, because thermal decomposition of PP and compatibilizer must be prevented.Compression molding was selected as the molding method because it allows molding with a small amount of sample. The binary blends of PP and LCP showed a degradation of tensile properties compared to pure PP. However, the addition More >

Abstract In the present paper, we report the synthesis of a new amino polymer made of oxazolidinone using an efficient ecocatalyst called Maghnite-H⁺. The synthesis process contains two steps: the first consists to the preparation of an amino oxiran 3-(oxiran-ylmethyl) oxazolidin- 2-one (OMO) by a substitution reaction of epichlorhydrin by 2-oxazolidinone, the second step concerns a green polymerization of the resultant oxiran by a ring opening reaction catalysed by Maghnite-H⁺. The polymer have been successfully prepared and characterized by various techniques, such as ¹H NMR, ¹³C NMR, IR, which were used to elucidate the structural characteristics of the More >

Abstract The Yes-associated protein (YAP) is a downstream effector of the Hippo pathway and acts as a key transcription co-factor to regulate cell migration, proliferation, and survival. The Hippo pathway is evolutionarily conserved and controls tissue growth and organ size. Dysregulation and heterogeneity of this pathway are found in cancers, including oral squamous cell carcinoma (OSCC), leading to overexpression of YAP and its regulated proliferation machinery. The activity of YAP is associated with its nuclear expression and is negatively regulated by the Hippo kinase-mediated phosphorylation resulting in an induction of its cytoplasmic translocation. This review focuses More >

Abstract Melanoma is one of the most aggressive types of malignant tumors, commonly affecting young individuals. The treatment of metastatic tumors remains obscure due to the resistance of tumor cells to drugs mediated by various mechanisms. The acquisition of a resistant phenotype is associated with both genetic and epigenetic alterations in cancer cells. Therefore, the current study aimed to investigate whether microRNA (miR)-204-5p could promote alterations in the cell cycle and apoptosis of dacarbazine (DTIC)-treated melanoma cells. Quantitative real time PCR showed that transfection of DTIC-treated SK-MEL-2 melanoma cells with miR-204-5p mimics significantly upregulated miR-204-5p. However,… More >

Abstract The Kazdin Method™ is a version of parent management training in which parents are trained to alter the behaviors of their children. The method draws on the principles and techniques of applied behavior analysis. The techniques focus on antecedents (what comes before the behavior), behavior (crafting the precise behaviors one wishes to develop), and consequences (usually praise to increase the likelihood that the desired behaviors will be performed again). The key focus is repeated practice in changing parent and child behaviors. The article traces the evolution of my use of parent training to treat severe More >

Abstract Among the harmful occupational factors, noise is the most common exposure in the oil industrial workplaces. The present study aimed to prioritize sound pollution areas in central processing facilities (CPF) of an oil field in order to provide corrective action in the studied industry and similar industries. After reviewing the issued permit to work, job description and noise dosimetry test, the evaluated areas were selected then sound pressure levels in the referenced areas investigated according to ISO 9612–2009 (E) next the noise map prepared for all selected areas. For identifying the prioritized areas to implement… More >

Abstract The room's plan shape, the area of the window, and the impact of the materials are significant parameters in determining the thermal needs of buildings. In traditional houses of the hot and dry climate of Iran, the plan shape of the room, the ratio of the window area to the floor area, and the comparison between traditional and prevalent materials have been less studied. This study investigated the thermal performance of seven different models of the plan shape, five different ratios of window area to plan area, and three material structures in a selected room… More >

Abstract In most of Arabian courtiers Rhazya stricta is extensively utilized in public medicine for several diseases treatment. In this study, crude alkaloid extract of R. stricta (CAERS) coated with silver nanoparticles (CAERS-AgNPs) as potential treatment against diabetes in DM animal model was evaluated. Swiss albino male rats (n = 80) were injected with STZ to induce Diabetes Mellitus type-2 (DM). DM-rats were injected different doses of CAERS or CAERS-nanoparticles (CAERS-NPs) for 2 months. The results exhibited that mRNA expression of insulin and insulin receptor was down-regulated, activity levels of antioxidant enzymes were decreased, generation of ROS mediated DNA adducts… More >

Abstract To identify and characterize genes involved in reproductive tissue abscission in Brassica oleracea, the transcript data of pollinated pistil was analyzed. A differentially expressed gene, named BoFAZ1(FLOWER ABSCISSION ZONE1) was identified, which contains one exon and encompass a 139aa. Furthermore, a T-DNA insertion mutant (SALK_302_G01) (faz1 mutant) was obtained from Arabidopsis thaliana mutant library. Floral organ shedding from mutants was delayed and a V-shaped structure in the boundary region between the stalk and torus of the sepal abscission zone was obtained in faz1 mutant. The cell density of this structure was lower than that of the corresponding region in… More >
