Exercise and supplementation prevent the dysfunction of BDNFand disorder in the serum levels ofCRPandIL-6caused by diabetes.The purpose of the study wasto determine the simultaneous effect of2months of combined training and taurine supplementation onBDNF,CRPandIL-6indices in diabetic rats.In this experimental study.30 adult male Wistar rats(250-300 grams and aged six weeks)were randomly divided into three groups diabetic exercisesupplementation(n=10),diabetic control(n=10)and healthy control(n=10).At the end of the8weekold,the amount of 55 mg/kg of body weight of streptozocin(STZ)was injected intraperitoneally,to make diabetic.The diabetic exercise-supplementation group performed the two months of combined exercises,5timesperweek(aerobic exercise with75%Vo2max on the treadmill and strength training includes15 times climbing the ladder).Taurine supplement was available to rats in the form ofa1%solution in daily drinking water(500 ml).The serum levels of BDNF,CRP and IL-6 were measured with Eliza method.OnewayANOVAand posthoc Tukey test were used to compare betweengroup and intragroup changes of BDNF,CRP,IL-6.The significance levelwasP<0.05.After two months of aerobicstrength training and taurine supplementation,BDNFserum level significantly increased in the diabetic exercise group compare to the diabetic group(P=0.003).Whereas,it significantly decreased in the diabetic control group compared to the healthy control(P=0.0001).CRPserumlevel significantly decreased in the diabetic exercise-supplementation group compare to the diabetic group(P=0.008).Whereas, it significantly increased the diabetic controlgroup compared to the healthy control(P=0.0001).After2months of aerobicstrength training and taurine supplementation there was no significant change inIL-6 serum level in the diabetic exercisesupplement group compared tothe diabetic control group andinthe diabetic control group compare to the healthy control(P=0.059).According to the findings ofthis research,2months of simultaneous aerobic-strength training and taurine supplementation are recommended to increaseBDNFlevels and reduce inflammationin diabetics.

Introduction: The aim of this study was to evaluate the effects of high-intensity interval training (HIIT) and curcumin supplementation on cardiac heat shock proteins level and gene expression level of microRNAs in rats exposed to arsenic.Methods: 32 male Wistar rats were randomly divided into four groups of Control, Curcumin, Exercise and concomitant(Curcumin+Exercise). Arsenic 5 mg/kg.day and curcumin 15 mg/kg.day, were consumed orally for entire the study period. HIIT were conducted for six weeks (5 d/w, 60 min/session (consisted of 10 intervals of running (4 min) at 85-90% of Vo2max with 2 min recovery at 50-60% of Vo2max). Tissue protein content and gene expression levels was assessed by Western blotting and PCR methods respectively. Results: No between group difference was observed for gene expression levels of miR-21(P>0.05).The cardiac HSP60, HSP20 levels and the gene expression levels of miR-30 was significantly higher in all three intervention groups compared to Control group(P<0.001). Moreover, the cardiac HSP60, HSP20 content was significantly higher in concomitant group compared to both groups of Exercise and Curcumin(P<0.05). Conclusion: Arsenic exposure may likely increase the vulnerability of cardiomyocytes to injury by altering the amount of heat shock proteins content and the expression levels of microRNAs. Both HIIT and curcumin supplementation could be likely effective to reduce the hazards of arsenic within heart, However, the concomitant intervention might be had more beneficial effects. However, more research is still needed to be done due to the lack of similar evidence and no comprehensive measurement of the influential factors.
