To improve compliance, merely educating patients is not sufficient and more efforts should be undertaken toward ensuring true sense of the problem and its impact. Factors affecting compliance due to the physical properties in the patch itself should be addressed too (heat, irritation, poor adhesive material and design).
BackgroundProgranulin is an adipokine, encoded by the progranulin (GRN) gene. Progranulin is expressed in atherosclerosis, but its effects in cardiac ischemia and reperfusion injury are unknown. Therefore, this study aimed to investigate the effects of progranulin in a rat model of acute myocardial ischemia/reperfusion (MI/R) injury in vivo.Material/MethodsThe model of acute MI/R injury was established in male Wistar rats by ligation of the left anterior descending (LAD) coronary artery for 30 minutes and reperfusion for 60 minutes. Before modeling, one group was treated with progranulin (0.03 μg/kg), and one group was treated with the P13K/Akt inhibitor, LY294002 (3 mg/kg). Left ventricular function (LV) was monitored, including the LV systolic pressure (LVSP), LV end-diastolic pressure (LVEDP), and changes in LV pressure. At the end of the study, blood and myocardial tissue were examined. Cardiac biochemical markers, histopathology, gene expression, and apoptosis were analyzed.ResultsProgranulin improved cardiac function following acute MI/R injury and significantly improved recovery of cardiac contractility and LVSP. Progranulin significantly reduced myocyte apoptosis, inflammation, and tissue edema, and was highly expressed in cardiac tissue following MI/R injury. The cardioprotective effect of progranulin was reduced by blocking the P13K/Akt signaling pathway.ConclusionsIn the rat model of acute MI/R injury, progranulin had a protective effect on cardiac function and morphology, associated with activation of the P13K/Akt signaling pathway. The mechanisms of the anti-apoptotic, anti-inflammatory, and inotropic effects of progranulin in the setting of acute MI/R injury require further in vivo studies.
Genre constitutes the rhetorical features of a text and the semiotic communicative purpose(s) it serves. It has marveled Systemic Functional Linguistics’ (SFL) scholars as to whether it should be treated as an aspect of the situational context (register) or as a distinct cultural semiotic system that correlates with texture- i.e. the three register categories of field, tenor, and mode. This paper aims to review the conceptualization of genre in the Systemic Functional Linguistics (SFL) tradition. Whereas Halliday associates genre with mode, Martin coordinates the three register variables of field, tenor, and mode in relation to social purpose. The elements of a schematic structure are generated by genre networks, which in turn preselect particular values of field, tenor and mode in a given culture. Both Halliday's context of situation and Martin’s context of culture levels are dynamic connotative semiotic systems through which new meanings are created by the three processes of semogenesis. Genre is conceived as a distinct cultural semiotic system, rather than an aspect of ‘mode’, that correlates with texture. Martin later avoided the intertextual glosses context of culture and context of situation since Halliday used them for instantiation, and not supervenience. The three register variables of language organize information at the level of genre into coherent texts. Modelled as register and genre, the stratified model of context configures meanings not only through discourse semantics, lexicogrammar, and phonology but also through the prosodic phases of evaluation. Halliday calls this model appliable linguistics since it enables us to develop a powerful model of language that is both “theoretical” and “applied” (Mahboob & Knight, 2010).
