Previously, we developed the pVAXrbd DNA vaccine encoding the receptor-binding domain (RBD) of SARS-CoV-2, which, when administered intramuscularly to animals, induced a relatively weak immune response. The next stage of the study is to increase the immune response, in particular, using electroporation as one of the methods for increasing the immunogenicity of DNA vaccines. \u0000AIM: The aim of this article is to evaluate the immune response using electroporation in mice after immunization with pVAXrbd. \u0000MATERIALS AND METHODS: BALB/c mice were immunized with pVAXrbd using direct and reverse polarity square wave direct current electroporation with three pulses of 12 V for 30 ms and an interval of 950 ml with a current limit of 45 mA. \u0000RESULTS: BALB/c mice were immunized twice with an interval of three weeks with a dose of 100 g of DNA. Using ELISA, the titers of RBD-specific antibodies in the group of animals immunized with pVAXrbd using electroporation were 1:109350, which is 16 times higher than in the group of animals that received the DNA vaccine only intramuscularly (titers 1:6750). IFN ELISpot analysis showed that the largest number of cells (2434 spots/splenocytes, million) producing IFN in response to stimulation with peptides from the RBD protein was registered in the group of animals immunized with pVAXrbd using electroporation. For comparison, in the control group, the number of cells is 6.5 times lower: 380 spots / splenocytes, mln. \u0000CONCLUSIONS: Administration of the pVAXrbd DNA vaccine to laboratory animals by electroporation significantly enhances both the humoral and cellular specific immune response compared to intramuscular administration of the naked DNA vaccine.","PeriodicalId":342669,"journal":{"name":"Medical academic journal","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114430138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Violation of rhythm leads to a mismatch of body functions, as a result to disadaptation, the occurrence of desynchronosis and the development of a number of socially significant diseases. \u0000AIM: Study of influence of constant lighting, chronic alcohol intoxication and joint action of these factors on diurnal dynamics of several electrolytes in blood of rats. \u0000MATERIALS AND METHODS: The study was conducted on 160 male of Wistar outbred stock at age of 6 months, with body weight of 300 20 g, which were divided into 4 groups. Control group animals, which were kept under conditions of fixed light regime (light:darkness = 10:14 hours), I group animals, which were kept under conditions of fixed light regime, but received a 15% water solution of ethanol as a drink, II group animals, which were kept under conditions of constant light regime, III group animals, which were kept under conditions of constant light regime and received a 15% water solution of ethanol as a drink. In blood samples, taken at 9:00, 15:00, 21:00 and 3:00 oclock, the concentration of total calcium, potassium, sodium, chlorine and phosphorus was measured. The reliability of circadian rhythmicity was determined through cosinor analysis. \u0000RESULTS: The increase in the concentration of phosphorus in the blood plasma of animals of II and III experimental groups was found with the decrease in the concentration of total calcium in animals of I and III experimental groups. Constant lighting and chronic alcohol intoxication affect the amplitude-phase characteristics of the circadian rhythms of all studied ions, and the combined action of these factors causes the destruction of the circadian rhythms of the studied electrolytes. \u0000CONCLUSIONS: It is established that the three-weeks-long influence of the studied chronodestructors leads to disruptions in metabolism of calcium and phosphorus, which are the most pronounced at joint action of darkness deprivation and chronic alcohol intoxication, and also to the significant disruptions in the structure of CRs of all of studied substances.","PeriodicalId":342669,"journal":{"name":"Medical academic journal","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116201519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The JNK and NF-B signaling pathways play a leading role in the progression of brain tissue inflammation, which may represent a promising target for therapeutic effects. \u0000AIM: To evaluate the effect of new derivatives of 3-formylchromone on the course of neuroinflammation reactions and the activity of JNK and NF-B translational pathways in brain tissue in rats with cerebral ischemia. \u0000MATERIALS AND METHODS: Cerebral ischemia was modeled in Wistar rats by irreversible right-sided occlusion of the middle cerebral artery. The studied compounds and the reference (ethylmethylhydroxypyridine succinate) were administered per os at doses of 30 and 100 mg/kg, respectively. After 72 hours of ischemia, changes in the concentration of proinflammatory cytokines were evaluated in the cerebrospinal fluid: IL-6, IL-1, IL-8 and TNF-. The content of JNK and NF-B in brain tissue was determined by enzyme immunoassay. \u0000RESULTS: The use of the test compounds 3FC1, 3FC2, 3FC4 and 3FC5, as well as the reference medicine, contributed to a decrease in the content of proinflammatory markers in the liquor. At the same time, the most significant decrease was noted when the compound 3FC5 was administered to animals, namely, the concentration of IL-1, IL-6, IL-8 and TNF- was lower relative to similar indicators of the group of animals without treatment by 30.0% (p 0.05); 64.5% (p 0.05); 48.5% (p 0.05) and 56.6% (p 0.05), respectively. The use of the fluorine-containing compound 3FC3 did not significantly affect the course of brain tissue inflammation reactions in rats. Evaluation of changes in the activity of JNK and NF-B showed that the studied substances inhibit the NF-B translational pathway and do not affect JNK, which is probably due to the activation of these signaling pathways and the antioxidant potential of the studied molecules. \u0000CONCLUSIONS: The use of compounds that are derivatives of 3-formylchromone in conditions of experimental cerebral ischemia contributes to the reduction of neuroinflammation reactions by inhibiting the NF-B pathway, without affecting the activity of the JNK-dependent signaling system. The substance with the highest pharmacological effects is the compound 3FC5, which contains a spatially hindered phenolic hydroxyl in its structure.","PeriodicalId":342669,"journal":{"name":"Medical academic journal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131055502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only a few studies of molecular changes in the myocardium in statin myopathy are presented in the literature. However, the myocardium, as a type of muscle tissue, can also be involved in the pathological process. In this regard, in our opinion, it is advisable to analyze the biochemical changes in the rat myocardium against the background of the use of simvastatin. \u0000AIM: To analysis of the dynamics of changes in the end products of glycolysis and the isoform composition of the giant protein titin in the heart muscle in animals with experimental hypercholesterolemia on the background of long-term administration of simvastatin. \u0000MATERIALS AND METHODS: The study was carried out on outbred male rats divided into 3 groups: control group (35 individuals) intact animals; comparison group (35 animals) intact animals treated with simvastatin for two months; experimental group divided into: subgroup 1 (35 individuals) animals with induced alimentary hypercholesterolemia, subgroup 2 (35 individuals) animals with induced alimentary hypercholesterolemia, which were administered simvastatin for two months. During the experiment, the content of the giant sarcomere protein titin, as well as changes in the concentration of pyruvate and lactic acid in the myocardium of the animals of the studied groups were studied. \u0000RESULTS: In animals with a physiological course of metabolic processes, the administration of simvastatin caused the accumulation of lactic acid in the myocardium. Under conditions of alimentary hypercholesterolemia under the influence of simvastatin, a decrease in the elevated level of pyruvate and lactic acid was revealed, which is obviously due to a decrease in pathobiochemical shifts in energy metabolism. The determination of the isoform composition of titin made it possible to establish that the administration of simvastatin under conditions of alimentary hypercholesterolemia contributed to the appearance of early dystrophic changes in the myocardium, which is consistent with the results of earlier studies of impaired myocardial contractile activity under the influence of statins. \u0000CONCLUSIONS: The results obtained indicate the need for a more thorough study of statins in terms of their safe use in patients with cardiovascular pathology.","PeriodicalId":342669,"journal":{"name":"Medical academic journal","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133699683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
