The aim of the work was the search for materials from experimental and clinical studies reflecting the pathogenetic role of the possible use of succinates for the correction of hypoxia in COVID-19. Materials and methods. 79 foreign and domestic literature sources were analyzed concerning the pathogenesis of COVID-19 and the pathogenetic role of succinates in hypoxia under conditions of COVID-19, oxidative stress, and diaphragmatic dysfunction were analyzed. The literature search was carried out using Pubmed and ELIBRARY.ru databases. Results. As the analysis of the literature has shown, tissue hypoxia is the basis of COVID-19 pathogenesis, triggering the entire cascade of  pathomorphological events leading to the development of multiple organ failure. A number of experimental and clinical studies (on a fairly large number of patients) reflect the positive effect of tissue hypoxia correction using succinates, both in adult patients and in children with a different spectrum of pathology associated with acute respiratory failure syndrome. Conclusion. Analysis of literature data allows to substantiate the prospect of using preparations containing succinate (reamberin, cytoflavin) in the complex therapy of severe cases of COVID-19.

Objective: the present study was aimed to evaluate the role of pharmaceutical services in improving the outcome of mineral bone disorder in patients with advanced chronic kidney disease. Methodology: One hundred and twenty patients with chronic kidney disease-mineral bone disorder (CKD-MBD) screened for eligibility, seventy-six patients enrolled in the study and randomly allocated into two groups: pharmaceutical care and usual care, both groups interviewed by the pharmacist using specific questionnaire for assessing the quality of life (QoL). All the drug related problems (DRPs) including drug-drug interactions (DDIs) were recorded by the pharmacist. Blood samples were collected and utilized for analyzing the levels of vitamin D, phosphorous, calcium, albumin and parathyroid hormone at baseline and three months after. The pharmaceutical care group received all the educations about their medications and how to minimize DRPs; improve the QoL. Additionally, the pharmaceutical intervention included correcting the biochemical parameters. Results: Pharmaceutical care significantly improved patients QoL and minimized DRPs and DDIs. It was also effective in improving the biochemical parameters. Conclusion: Pharmaceutical care has a positive impact on improving the outcome of patients with CKD-MBD through attenuating DRPs, improving the biochemical parameters and the QoL.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

Perceived Desirability

This research investigates the determinants of entrepreneurial intention among Vietnamese employees, a crucial segment of potential entrepreneurs yet mostly neglected in previous studies. Given the focus on intention to create an international business venture and the working segment, we expand the entrepreneurial event theory by supplementing perceived competence and job satisfaction as determinants of entrepreneurial intention while testing the mediation of perceived feasibility and perceived desirability in such relationships correspondingly. Three focus groups on 27 Vietnamese employees were conducted to explore the specific relevant competences and develop the conceptual model. Afterwards, data from an empirical survey on 567 Vietnamese employees was analysed using a partial least squares structural equation model to test the hypothesised relationships. The empirical results indicate that perceived competences, viz. administrative competence, communication skills, network building competence, and international business expertise have a positive impact on entrepreneurial intention. The relationships between either administrative competence, network building capacity or international business expertise, and entrepreneurial intention are totally mediated by perceived feasibility. The study also reveals a noteworthy finding about the negative direct effect of overall job satisfaction on entrepreneurial intention and the partial mediating role of perceived desirability in this relationship.

Background: Myocardial redox state is a critical determinant of atrial biology, regulating cardiomyocyte apoptosis, ion channel function, and cardiac hypertrophy/fibrosis and function. Nevertheless, it remains unclear whether the targeting of atrial redox state is a rational therapeutic strategy for atrial fibrillation prevention. Objective: To review the role of atrial redox state and anti-oxidant therapies in atrial fibrillation. Method: Published literature in Medline was searched for experimental and clinical evidence linking myocardial redox state with atrial fibrillation pathogenesis as well as studies looking into the role of redoxtargeting therapies in the prevention of atrial fibrillation. Results: Data from animal models have shown that altered myocardial nitroso-redox balance and NADPH oxidases activity are causally involved in the pathogenesis of atrial fibrillation. Similarly experimental animal data supports that increased reactive oxygen / nitrogen species formation in the atrial tissue is associated with altered electrophysiological properties of atrial myocytes and electrical remodeling, favoring atrial fibrillation development. In humans, randomized clinical studies using redox-related therapeutic approaches (e.g. statins or antioxidant agents) have not documented any benefits in the prevention of atrial fibrillation development (mainly post-operative atrial fibrillation risk). Conclusion: Despite strong experimental and translational data supporting the role of atrial redox state in atrial fibrillation pathogenesis, such mechanistic evidence has not been translated to clinical benefits in atrial fibrillation risk in randomized clinical studies using redox-related therapies.

: Thymoquinone (TQ) is one of the leading phytochemicals, which is abundantly found in Nigella sativa L. seeds. TQ exhibited various biological effects such as antioxidant, anti-inflammatory, antimicrobial, and anti-tumoral in several pre-clinical studies. Parkinson's disease (PD) is a long-term neurodegenerative disease with movement difficulties, and the common feature of neurodegeneration in PD patients is caused by dopaminergic neural damage in the substantia nigra pars compacta. The neuroprotective activity of TQ has been studied in various neurological disorders. TQ-mediated neuroprotection against PD yet to be reported in a single frame; therefore, this review is intended to narrate the potentiality of TQ in the therapy of PD. TQ has been shown to protect against neurotoxins via amelioration of neuroinflammation, oxidative stress, apoptosis, thereby protects neurodegeneration in PD models. TQ could be an emerging therapeutic intervention in PD management, but mechanistic studies have been remained to be investigated to clarify its neuroprotective role.
