Although antioxidants, redox modulations, and neuropsychiatric disorders have been widely studied for many years, the field would benefit from an integrative and corroborative review. Our primary objective is to delineate the biological significance of compounds that modulate our redox status (i.e., reactive species and antioxidants) as well as outline their current role in brain health and the impact of redox modulations on the severity of illnesses. Therefore, this review will not enter into the debate regarding the perceived medical legitimacy of antioxidants but rather seek to clarify their abilities and limitations. With this in mind, antioxidants may be interpreted as natural products with significant pharmacological actions in the body. A renewed understanding of these often overlooked compounds will allow us to critically appraise the current literature and provide an informed, novel perspective on an important healthcare issue. In this review, we will introduce the complex topics of redox modulations and their role in the development of select neuropsychiatric disorders.

Abstract Background GATA6 is a transcription factor that can be used to distinguish between the basal-like and classical subtypes of pancreatic ductal adenocarcinoma (PDAC). The basal-like subtype has been demonstrated to be less responsive to modified FOLFIRINOX chemotherapy and thus can be used to predict response to specific chemotherapies. To date, GATA6 expression has only been evaluated in surgically resected PDAC specimens. Less than 15% of patients with PDAC are eligible for surgery. Endoscopic ultrasound guided fine-needle aspirate (EUS-FNA) and biopsy (EUS-FNB) can potentially help assess GATA6 expression in PDAC and in turn, help guide personalized treatment selection in all cases of PDAC. Aims The primary objective of this study was to explore the yield of EUS-FNA and EUS-FNB for the detection of GATA6 among patients with PDAC. The study also aimed to explore the impact of lesion location on sample adequacy and type of fixative on validity of GATA6 staining. Methods This study was conducted from November 2017 to October 2019. Consecutive patients with a diagnosis of PDAC confirmed by biopsy were included. Patients underwent either EUS-FNB or EUS-FNA to obtain tissues samples. Samples were fixed in either neutral buffered formalin (NBF) or a methanol based buffered solution (Cytolyt) and evaluated by a specialized cytopathology team. Fisher’s exact test was used and a p-value ≤0.05 was considered to indicate statistical significance. Results Forty-four patients were included in the study. Twenty-three (52%) patients were male and the median age of patients was 67.5 years. Twenty-five lesions were located in the head and neck of the pancreas, 14 were located in the body, and 4 were located in the tail. One patient was found to have a local recurrence of PDAC at the surgical bed of a previous Whipple procedure. Eighteen lesions were sampled by EUS-FNA and 26 were sampled using EUS-FNB. Thirty-eight (86%) samples were adequate for assessment of GATA6. Sampling technique (p=0.68) and fixative type (p=1.00) did not appear to affect sample adequacy. Compared to pancreatic body or tail specimens, samples obtained from the head or neck of the pancreas were more likely to be inadequate for analysis (p=0.03). Conclusions EUS-FNA and EUS-FNB samples are efficacious methods of assessing GATA6 expression in PDAC. This is the first predictor of treatment response that has been demonstrated to be obtained without surgical resection. Neither EUS needle type or alcohol fixation before cell block preparation appear to impact GATA6 detection. Lesions in the pancreatic head or neck appear to be associated with higher rates of sample inadequacy. Larger, prospective studies are required to confirm our findings. Funding Agencies None

The article reveals the relationship between physical activity and a healthy lifestyle of higher education. The concept of a healthy lifestyle and physical activity is defined. An approach to determining the norms of motor activity is proposed, which is based on taking into account the impact of muscular activity on health, functional reserves of the body, physical fitness. It was found that physical activity is determined by biological, socio-economic and cultural factors and depends on the type of occupation, individual psychological, physical and functional characteristics of man, the amount of free time and the nature of its use, accessibility of sports facilities and recreation areas, and climatic and geographical conditions. Many authors have proven that the main component of a healthy lifestyle is physical activity. Experts point out that physical activity is an important factor in maintaining high human performance. It acts as a means of motor function and has a general biological significance. Muscle activity has been shown to be the best way to stimulate various body systems. Healthy lifestyle in the domestic literature means such forms and ways of daily life that meet the principles of hygiene, strengthen the adaptive capacity of the body, contribute to the successful recovery, maintenance and development of reserve capabilities, full performance of social functions.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Introduction. The impact on the body of such factors of the production environment as coal-rock dust and fluorine compounds leads to certain shift s in strict indicators of homeostasis at the system level. Maintaining the relative constancy of the internal environment of the body is provided by the functional consistency of all organs and systems, the leading of which is the liver. Organ repair plays a crucial role in restoring the structure of genetic material and maintaining normal cell viability. When this mechanism is damaged, the compensatory capabilities of the organ are disrupted, homeostasis is disrupted at the cellular and organizational levels, and the development of the main pathological processes is noted.The aim of the study is to compare the morphological mechanisms of maintaining structural homeostasis of the liver in the dynamics of the impact on the body of coal-rock dust and sodium fluoride.Materials and methods. Experimental studies were conducted on adult white male laboratory rats. Features of morphological mechanisms for maintaining structural homeostasis of the liver in the dynamics of exposure to coal-rock dust and sodium fluoride were studied on experimental models of pneumoconiosis and fluoride intoxication. For histological examination in experimental animals, liver sampling was performed after 1, 3, 6, 9, 12 weeks of the experiment.Results. The specificity of morphological changes in the liver depending on the harmful production factor was revealed. It is shown that chronic exposure to coal-rock dust and sodium fluoride is characterized by the development of similar morphological changes in the liver and its vessels from the predominance of the initial compensatory-adaptive to pronounced violations of the stromal and parenchymal components. Long-term inhalation of coal-rock dust at 1–3 weeks of seeding triggers adaptive mechanisms in the liver in the form of increased functional activity of cells, formation of double-core hepatocytes, activation of immunocompetent cells and endotheliocytes, ensuring the preservation of the parenchyma and the general morphostructure of the organ until the 12th week of the experiment. Exposure to sodium fluoride leads to early disruption of liver compensatory mechanisms and the development of dystrophic changes in the parenchyma with the formation of necrosis foci as early as the 6th week of the experiment.Conclusions. The study of mechanisms for compensating the liver structure in conditions of long-term exposure to coal-rock dust and sodium fluoride, as well as processes that indicate their failure, and the timing of their occurrence, is of theoretical and practical importance for developing recommendations for the timely prevention and correction of pathological conditions developing in employees of the aluminum and coal industry.The authors declare no conflict of interests.
