Background and Objective: The Candida albicans is an opportunistic fungi that can be pathogenic in patients suffering from diabetes and AIDS. This organism can cause various infections such as superficial of the skin and mucosa to deep tissue infections. In this study the antifungal effects of ZnO and SDS on Candida albicans in comparison with Fluconazole were investigated. Materials and Methods: This was an experimental study which evaluated the antifungal effects of biocide SDS and ZnO on Candida albicans by microbroth dilution assay in broth and agar medium. Minimum Inhibitory Concentration (MIC) was determinated for each inhibitor during colony count in comparison with control. Results: MIC of ZnO was 1.013-296 µg/ml and for SDS and Fluconazole were 0.001-0.56 and 0.062-128 µg/ml respectively. Conclusion: This study demonstrated antifungal activity of ZnO can be a candidates for the elimination of candida in medicine particular in medical instruments.

Background and Objective: Aging is associated with increased free radical production. On the other hand, sports activities with the improvement of antioxidant system can reduce the damage caused by aging. This study was performed to determine the effect of the coantinus training (MCT) and high intensity interval training (HIIT) on antioxidant enzymes in the heart of old rats.

Methods: This experimental study was performed on 24 male Wistar rats aged 22-24 months. After two weeks of adaptation, animals were allocated into three groups including HIIT (8 rats: 100-80% maximum speed), MCT (8 rats: 65-70% maximum speed) and control group (8 rats the control group did not receive any intervention during the study. The training protocol was performed 5 days in week for 6 weeks. The heart tissues of rats were extracted 48 hours after the last training session. Gene Expression of superoxide dismutase (SOD) and glutathione peroxidase (GPX) was analyzed by the ELISA test.

Results: SOD was significantly increase in MCT (41.26±3) and HIIT (48.8±6) groups in compare to control (22.62±2) (P<0.05). GPX was significantly increased in MCT (1.96±0.07) and HIIT (2.28±0.03) groups in comparision with controls (1.37±0.04) (P<0.05) and this increase was higher in the HIIT group than in continuous training group.

Conclusion: Continues training and high intensity interval training increase the amount of antioxidant enzymes in heart tissue of aging rats.

Background and Objective: Age is the greatest risk factor for cardiovascular disease that is associated with shortens telomere. TRF2 and TERT genes expression in heart tissue   reduce in elderly. These geness are associated with shortens telomere. Exercise can play a useful role in maintaining the length of telomeres. This study was carry out to determine the effect of high intensity interval training (HIIT) and continuous endurance training on TRF2 and TERT gene expression in heart tissue of aged male rats.

Methods: In this experimental study 24 adult aged male rats (88-96 weeks, 363±12 g) allocated into three groups including control, endurance training (5 sessions per week: with 60-70 of maximum speed of group) and HIIT (5 sessions per week: 80 percent in the first and second week, 90% maximum speed of the third week, 100 % until the end of the exercise for 6 weeks). Gene expression of TRF2 and TERT were assessment by Real-time - PCR and the quantification of gene expression levels using the Pfaffl formula.

Results: TRF2 gene significantly increased in HIIT and CET groups in compared to control group (P<0.05). TERT gene non- significantly increased in HIIT and CET groups in compared to the control group.

Conclusion: It seems, 6 weeks of high-intensity interval training and continuous endurance training to be able regulate the growth and longevity of the heart cells by maintaining the length telomere by increasing TRF2 gene expression.
