Abstract
Introduction: Nanoparticles accumulate easily in the organs of the body due to their small size. Therefore, an increase in the use of nanoparticles leads to more concerns about their side effects. Accordingly, the present study was conducted to investigate the effect of aerobic exercise on the renal Apelin and Nitric Oxide (NO) levels in male rats exposed to zinc oxide nanoparticles.
Materials & Methods: In this experimental study, 35 male Wistar rats with a weight range of 150-170 g were randomly divided into five groups of seven animals per group. The groups included control, salin, zinc oxide nano, exercise, and exercise+zinc oxide nano. The zinc oxide nano (1mg/kg) was administered intraperitoneally 5 times/week to the exercise and exercise+zinc oxide nano groups. The exercise program consisted of progressive running on a treadmill (speed from 15 to 18 m/min, 25 to 44 min/day, five times per week for four weeks). The rats were euthanized two days after the last intervention. The kidney tissues were removed and homogenized to measure the levels of Apelin, NO, and Malondialdehyde (MDA). The data were analyzed through a one-way ANOVA test (P<0.05).
Ethics code: 20821404942014/6-1395
Findings: The results indicated that the zinc oxide nano administration significantly increased renal MDA as well as NO and significantly decreased Apelin, compared to the control group. Moreover, the 4-week exercise training was associated with a significant decrease in the renal MDA in exercise and exercise+zinc oxide nano groups and a significant increase in Apelin levels in the exercise group. Exercise also induced a significant increase in the tissue NO levels in the healthy rats; however, it reduced NO level in the kidney of rats exposed to zinc oxide nano.
Discussions & Conclusions: It seems that regular exercise can exert its protective role against zinc oxide nanoparticle-induced renal injury by reducing oxidative stress, increasing Apelin, and modifying NO levels in the kidney tissue.

Abstract
Introduction: Consuming a high-fat diet causes obesity, which is one of the hallmarks of metabolic syndrome. The present study aimed to assess the effect of aerobic training and capsaicin supplementation on the expression of lipogenic genes SREBP-1c and FASN in the liver tissue of obese rats
Material & Methods: For this experimental research, 40 eight-week-old male Wistar rats weighing 181.5±2.3 grams were selected as samples. Thereafter, eight rats were fed a normal diet (ND), and 32 rats were fed a high-fat diet (HFD) and randomly assigned to five groups: normal diet, high-fat diet, high-fat diet-training, high-fat diet-capsaicin, and high-fat diet-training-capsaicin. The exercise groups performed an incremental aerobic exercise program (15-25 m/min, 30-60 min/day, five days/week) on a treadmill for eight weeks. Capsaicin (4 mg/kg/day) was taken orally by gavage once a day.
Results: Induction of obesity was associated with increased expression of SREBP-1C (P=0.001) and FASN (P=0.001). It was also revealed that aerobic exercise with capsaicin supplementation significantly decreased SREBP-1C and FASN gene expression in the experimental groups compared to the obese group. Finally, this reduction trend was significant in the combined group compared to the supplement group.
Discussion & Conclusion: It is possible that the use of capsaicin, along with aerobic physical activity, is an effective strategy to neutralize the markers of hepatic lipogenesis.
