Oxidative stress, resulting from excessive levels of ROS in semen, has a negative impact on functional parameters and sperm fertility. In this study we examined the influence of the oxidative stress induced by hydrogen peroxide (H2O2) in ovine sperm motility after thawing and catalase (CAT) ability to preserve sperm motility. Semen was incubated at 37°C with 100 ?M H2O2, 1 U catalase + 100 ?M H2O2 or no treatment, for 30 min. Immediately after adding treatments, sperm motility was determined by computer-assisted semen analysis (CASA). Incubation with H2O2 led to a significant (P < 0.05) decrease in motility parameters whereas catalase prevented a decline in motility secondary to oxidative stress. After 30 min of incubation with H2O2, total motility (12.0% vs. control 73.0%, H2O2 +CAT 70.0%), progressive motility (0.0% vs. control 19.0%, H2O2 +CAT 19.0%) and rapid motility (1.0% vs. control 43.0%, H2O2 +CAT 40.0%) decreased significantly (P < 0.05), whereas percentage of static cells increased (84.0% vs. control 18.0%, H2O2 +CAT 20.0%). We conclude that H2O2 causes damage to ovine sperm motility and that catalase is able to avoid detrimental effect of H2O2 on sperm motility. |

Passiflora tenuifila Killip is a wild species, with no studies regarding to functional properties. The objective of this work was to evaluate the chemical composition, including NMR and UPLC, toxicity and functional effect in a Parkinsonism model. The fruits (peel, pulp, and seed) were crushed, lyophilized and characterized. The subchronic toxicity was evaluated in Wistar rats during 90 days, and the Parkinsonism symptoms were induced by rotenone and after treated with P. tenuifila daily doses during 21 days. Composition results indicated a high total dietary fiber content, total polyphenols, and antioxidant activity. The subchronic toxicity results showed that garlic passion fruit did not present signs of toxicity. In the Parkinsonism model, the tests allow to indicate that the consumption of garlic passion fruit causes an improvement and possible effect of recovery of the damages induced by the rotenone, being these effects of improvement proportional to the consumption. |
