Aim: The aim of this study was to determine the Effects of aerobic training and High Fat Diet on the Gene Expression of Bax and Bcl-2 in the myocardium of adolescent male rats. Methods: forty young male rats (30 days old) randomized in normal diet control (NDC), normal diet training (NDT), high fat diet control (HFDC) and high fat diet training (HFDT) groups. HFD rats followed high fat regimen (5.817 kcal/g) for 30 days and the normal fat diet (3.801 kcal/g) was continued following to the 60th day of birth. Aerobic training was conducted for four weeks included on three training sessions from the 70th to 98th days of life. Results: Our findings showed that in HFD groups the expression of Bax protein (from the apoptotic susceptible protein family) was increased and exercise was quite effective in preventing this increase. Instead, the high-fat diet caused a (but brief and insignificant) decrease in the expression of the BCL2 protein (from the family of anti-apoptotic proteins), although the effect of exercise and high-fat diet was not significant. Also, High fat diet increased the ratio of Bax protein expression to BCL2 protein expression (as an index of overall outcome reflecting , while training was well able to prevent this increase. Conclusion: Overall, based on the results of this study, we conclude that consumption of high fat diet may also induce cardiac apoptosis even in adolescence and in addition to good physical activity in neutralizing these adverse effects of high fat diet is helpful.

Aim: we investigated the effects of six weeks of HIIT and curcumin supplementation on hepatic cellular death and also GSH level in male rats exposed to drinking water arsenic.Methods: 48 rats were randomized in six groups including HIIT, curcumin, HIIT+curcumin, arsenic, ethanol control and normal control. Arsenic 5 mg/bw.day and curcumin 15 mg/bw.day, were consumed orally for entire the study period. HIIT were conducted for six weeks (5 d/w, 60 min/session (with 4 min running at 85-90% of Vo2max and 2 min recovery at 50-60% of Vo2max intervals). Results: Arsenic exposure down regulated hepatic CK18 M65 level and also in a lesser extent; the cellular GSH content. Curcumin supplementation either alone or concomitantly with HIIT, could reverse the changes in hepatic CK18 M65 level. However; only in the HIIT+curcumin group, a remarkable elevation of hepatic GSH level was observed. Conclusion: Arsenic exposure renders liver to an increased oxidative stress and apoptosis level and the both HIIT and curcumin supplementation have appreciable effects to neutralize these hazardous effects. Moreover, only the synergistic effect of HIIT and curcumin supplementation could attenuate the liver antioxidants following arsenic exposure. However, more investigations remains to be done because of the study limitations and lack of similar evidence in this area.

Aim: Was to investigate the effects of eight weeks aerobic training and curcumin supplementation on some mitophagy indices induced by ischemia/reperfusion of male rats. Methods: Fifty eight (age: 12 weeks, weight: 315.23 ± 28.57 gr) male rats were randomized into five groups including on Healthy control, Ischemic cotrol, Curcumin, Training, Training+Curcumin(Concomitant). Aerobic training program were conducted for eight weeks (5 d/w) starting with running at a speed of 10 m/min, 5% incline for 10 min per day. The running speed and time were gradually increased up to 15-20 m/min per day. In the last two sessions, the intensity of aerobic training reached 25 m/min for 30 min per day with 2 min recovery period at 10 m/min. curcumin (200 mg/bw.day) were consumed through oral gavage for six weeks. The gene expression levels of miR-1 and miR-133 were evaluated using Real-Time PCR method and the data were analyzed using one-way analysis of variance and Tukey post hoc test at the significance level of p <0.05. Results: In all four intervention groups, including ischemia control, exercise, curcumin and combination, the expression of HIF-1α and BNIP3 in renal tissue increased significantly (p=0.001 in all groups) compared to the control group. However, the expression of HIF-1α and BNIP3 genes in renal tissue after exercise caused a significant decrease and increase (p=0.007 and p=0.01, respectively) compared to the healthy control and ischemic control groups. Also, curcumin and Concomitant were associated with an increase in HIF-1α and BNIP3 gene expression in renal tissue
