Autophagy is a cellular process that eliminates unnecessary cytoplasmic materials, such as long-age proteins, destroyed organelles, and foreign microorganisms. Macroautophagy (MaA), chaperone-mediated autophagy, and microautophagy are the three main types of autophagy. It is regulated by the integration of signaling from the AMPK and mTOR-ULK1 pathways. Autophagy plays a physiological role in health, and its dysregulation could be a pathophysiologic mechanism in different disease conditions. In the current study, we reviewed papers of Google Scholar database, PubMed, PubMed Central, Cochrane Database of Systematic Reviews, MEDLINE, and MedlinePlus with no time limitation and a recent World Health Organization report. In the current review, it could be concluded that autophagy plays many physiological functions, including immune system modulation, and regulates different cellular processes such as metabolism, protein synthesis, and cellular transportation. Dysregulation of autophagy is implicated in tumorigenesis, aging, age-related neurodegeneration, and endothelial dysfunctions. Autophagy dysregulation is also implicated in the newly discovered CoV-COVID-19 pathogenesis.

Background and aim of the work The current study postulated that cyclosporine A (CSA) could induce gender-specific renal damage. Hence, the current study aims to investigate the nephrotoxic effect of perinatal exposure of male and female rat progeny to CSA. Moreover, it aims to evaluate the oxidative stress and inflammation as a possible pathophysiologic mechanism. Materials and methods Female rats were randomly allocated to two groups of four and assigned to undergo either CSA (15 mg/kg/day; the 6th day after conception and continuing until the progeny were weaned) or vehicle treatment as control groups. At the age of 6 weeks, the progeny were divided into the following four groups: male progeny of control-group mothers (M-vehicle, 7); male progeny of CSA-treated mothers (M-CSA, 9); female progeny of control-group mothers (F-vehicle, 7); and female progeny of CSA-treated mothers (F-CSA, 6). Serum adiponectin, tumor necrosis factor-α (TNF-α) and creatinine, creatinine clearance, and urinary 8-isoprostane were measured. Histopathological examination by hematoxylin and eosin stain of Kidney was carried out. Results Proteinuria and decreased creatinine clearance are significant in M-CSA than M-vehicle and F-CSA. 8-isoprostane is lower in F-CSA than F-vehicle. Increased TNF-α and decreased adiponectin levels in M-CSA than M-vehicle were observed. No significant differences were found in female rat groups. Conclusion From the current study, it could be concluded that CSA could induce renal inflammation as well as oxidative stress that may explain the impaired renal function. The sex difference was a prominent finding in their vulnerability to CSA effects.

Background: The 2019-2020 coronavirus pandemic has affected educational systems worldwide, leading to widespread closures of schools and universities and social distancing Hence, the shift to an online tool was required Aims and Objectives: The main problem postulated is the lack of student-teacher interaction that occurs with online learning Methods: The Blackboard Collaborate Ultra platform was used to deliver lectures on clinical biochemistry and the reproductive module to our students Our main goal was to achieve students' engagement and interaction Results: There were 189 male students enrolled in the reproductive module The attendance rate was 93%-95% The download of the recording was 100% The active participation rate was up to 87% Hence, Blackboard Collaborate Ultra's virtual classrooms are very useful tools for online interactive lecturing Conclusion: Based on this experience gained, we could conclude that interactive virtual classroom lecturing can be used in addition to or instead of traditional lectures during ordinary situations as a successful online learning community tool © MEDKNOW 2020 All rights reserved
