Metabolismo oxidativo e cardíaco de equinos submetidos a exercício de baixa intensidade antes e após suplementação com antioxidante

The present study aimed to evaluate cardiac and lipoperoxidation markers in horses subjected to low intensity and long duration (TLD) exercise test, before and after vitamin E supplementation. For this purpose, 10 horses were used, subjecting them to the first TLD with a workload based on individual maximal oxygen uptake (VO2max). Then, horses received vitamin E (dl-alpha-tocopherol) during 59 days at a daily oral dose of 1,000IU, and thereafter they performed a second TLD with the same protocol as the first. Blood samples were collected to determine plasma malondialdehyde (MDA) as an index of lipoperoxidation, serum cardiac troponin I (cTnI) and creatine kinase MB isoenzyme (CK-MB) as cardiac markers. As a result of the exercise, there was no significant increase in MDA or cTnI, but serum CK-MB increased suggesting myocardial stress. The supplementation was able to minimize reactive oxygen species production, as evidenced by lower concentrations of MDA at all times evaluated, but it didn't cause protective effect on the myocardium. It was concluded that the low intensity and long duration exercise promoted light myocardial stress in horses and vitamin E supplementation reduced lipoperoxidation.

Antioxidantes e biomarcadores da injúria oxidativa na saliva de pacientes com síndrome de down

Vulnerability of patients with Down syndrome (DS) to oxidative stress and damage has been attributed to the overexpression of the superoxide dismutase gene, which is located in the triplicated critical region 21q22.2 of chromosome 21. The objective of this study was to investigate enzymatic and non-enzymatic antioxidant systems and levels of biomarkers of oxidative damage in saliva of patients with DS. Saliva samples were collected from 30 patients with DS and 30 controls, ranging in age from 14 to 24 years. The following parameters were analyzed: superoxide dismutase activity, concentration of malondialdehyde, carbonylated proteins, uric acid, vitamin C and total protein, peroxidase activity, and total antioxidant capacity. Patients with DS presented significantly higher superoxide dismutase activity and malondialdehyde levels than controls (p<0.05). On the other hand, no difference in carbonylated proteins or antioxidants (uric acid, vitamin C, peroxidase, and total antioxidant capacity) was observed between DS patients and controls (p>0.05). Patients with DS also presented higher salivary total protein content (p<0.05). In conclusion, despite similar antioxidant levels patients with DS are more vulnerable to oxidative stress in saliva as indicated by a significant increase in malondialdehyde concentration and superoxide dismutase activity
