In addition to following the KD, the training groups performed aerobic or resistance training three days per week for six weeks. For statistical analysis, the mixed two-way analysis of variance test with a significance level of less than 0.05 and SPSS software was used.\u0000Results: The serum levels of adiponectin, resistin, and SFRP5 did not differ significantly between the groups. In all groups, resistin had a significant decrease, whereas adiponectin and SFRP5 had a significant increase, compared to the pre-test. The serum levels of glucose, insulin, and triglycerides, as well as insulin resistance and sensitivity indices, were not significantly different between the groups. A significant decrease in glucose and triglyceride levels was observed in the three groups compared to the pre-test. Both KD and AT-KD groups significantly decreased insulin and HOMA-IR and increased McAuley indices compared to the pre-test. Only the AT-KD group significantly increased the QUICKI index compared to the pretest.\u0000Conclusion: Both AT-KD and RT-KD improved the level of adipokines in overweight or obese men.

Pregnant female rats in the group of long-term anesthesia with ketamine were anesthetized once a week (at a dose of 75 mg/kg), and those in the groups of short-term and repeated anesthesia with ketamine were anesthetized 3 times a week (at a dose of 25 mg/kg). Ketamine injections were given weekly and regularly until the end of pregnancy. In order to evaluate the balance behavior of rats, a balance behavior test was conducted after lactation of all neonates of different groups. Moreover, tissue sampling was performed at the end of the whole period.\u0000Results: Most tissue changes were related to the Purkinje layer in the long-term group.

It has a tremendous effect on various aspects of human beings, including physical and mental health, cholesterol level control, and triglyceride level control. Moreover, it alleviates the dimensions of depression, psychosis, anxiety, obsession, interpersonal sensitivity, phobia, hostility, and paranoid thoughts. One of the most important effects of fasting on the human body is its influence on the immune system function. Significantly, it has been found that inflammatory biomarkers, such as IL-6 and C-reactive protein (CRP), are suppressed considerably by short- and long-term intermittent fasting. In overweight adults, calorie restriction (CR) improves clinical findings for patients with moderate asthma, reduces oxidative and inflammatory stress markers, and minimizes metabolic disease risk markers.","PeriodicalId":16423,"journal":{"name":"journal of north khorasan university of medical sciences","volume":"167 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77309726","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}

In the present study, changes in the levels of Eutoxin-1 and superoxide dismutase (SOD) were evaluated after 8 weeks of high-intensity interval resistance training (HIIRT) and vitamin D intake in overweight women with vitamin D deficiency.\u0000Method: In this clinical trial study, 52 overweight women with vitamin D deficiency were purposefully selected and then randomly assigned to exercise, vitamin D, exercise+vitamin D (combined), and control groups. HIIRT was performed 3 times a week in three sets with an intensity of 80% of a maximum repetition. Vitamin D was taken at a dose of 50,000 units weekly. Data were analyzed using paired t-test, one-way ANOVA, and Kruskal-Wallis tests with a significant level of less than 0.05.\u0000Results: After 8 weeks, SOD activity increased in the experimental groups, and the level of Eutoxin-1 decreased significantly. In addition, the rate of changes in SOD and Eutoxin-1 levels in the combined group was higher than those in the vitamin D group; however, no significant difference was observed between the exercise and combination groups (P<0.05).\u0000Conclusion: It seems that HIIRT and vitamin D intake can increase SOD activity and up-regulate Eutoxin-1 in overweight women. Moreover, co-administration of HIIRT with vitamin D intake can have stronger effects in reducing the inflammatory-oxidative effects of overweight and vitamin D deficiency by increasing SOD and decreasing Eutoxin-1, compared to the intervention of vitamin D consumption.","PeriodicalId":16423,"journal":{"name":"journal of north khorasan university of medical sciences","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88225504","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}

Today, stem cell therapy is an appropriate choice for MS management. Induced Pluripotent Stem Cells (iPSC) are pluripotent stem cells that have neuroprotective effects with neuroglial differentiation potential. In this study, we used iPSCs to improve remyelination and behavioral function in model of cuprizone multiple sclerosis disease in rats.\u0000Method: Human iPSCs were cultured and extended on a mouse embryonic fibroblast feeder cell layer inactivated with mitomycin-C in DMEM/F12 supplemented with 20% knockout serum replacement, 0.1 mmol/L nonessential amino acids, and 10 ng/mL of recombinant human basic fibroblast growth factor in a 5% CO2 and 95% humidity. The demyelination model was induced using a 0.2 oral Cuprizone regime. Thereafter, iPSCs were transplanted after six weeks. Remyelination was investigated via histological assessments and immunocytochemistry following six-week post-transplantation. The functionality was evaluated using behavioral tests, BBB, and Footprint following six-week post-transplantation.\u0000Results: The results of in vivo studies showed that after specific myelin tissue staining, the cuprizone diet led to the induction of demyelinated areas in the brain tissue six weeks after the cuprizone diet. Differentiation of transplanted cells was confirmed via the immunocytochemistry technique of PLP. The results of the Footprint test showed that the motor function of the paws of the animals improved compared to the control group. Moreover, BBB behavioral tests showed improved symptoms in the experimental groups that received the cells.\u0000Conclusion: In total, iPSCs can improve remyelination and functional recovery following transplantation into the Cuprizone demyelination model in rats.
