1. Lipid oxidation in meat: mechanisms and protective factors – a review
Abstract Lipid oxidation in meats is a process whereby polyunsaturated fatty acid react with reactive oxygen species leading to a series of secondary reactions which in turn lead to degradation of lipids and development of oxidative rancidity. This process is one of the major factors responsible for the gradual reduction of sensory and nutritional quality o

2. Chemical compositions and antioxidant activity of Heracleum persicum essential oil
ABSTRACT In this study essential oil of the aerial parts of Heracleum persicum a spice widely used in Iran was isolated by conventional hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD) techniques. The extraction yield was determined and the chemical compositions of essential oils were identified by the application of gas chromatography/

3. The Effects of Different Types of Antioxidants (Se, Vitamin E and Carotenoids) in Broiler Diets on the Growth Performance, Skin Pigmentation and Liver and Plasma Antioxidant Concentrations
Abstract This study investigated the effects of the addition of different antioxidants to broiler diets on their live performance, liver antioxidant composition and concentrations, immune response, and meat and skin color. A total of 945 three-day-old Ross 308 broiler chicks of both genders were randomly allocated to one of nine dietary treatments (n=105), w

4. Antioxidant supplements for prevention of mortality in healthy participants and patients with various diseases
BACKGROUND: Our previous systematic review has demonstrated that antioxidant supplements may increase mortality. We have now updated this review. OBJECTIVES: To assess the beneficial and harmful effects of antioxidant supplements for prevention of mortality in adults. METHODS: Search methods: We searched The Cochrane Library, Medline, Embase, Lilacs, the Sc

6. Efeito do ácido fólico nos principais parâmetros do espermograma de homens subférteis / Effect of folic acid in the main parameters of seminal analysis
Research shows that oral supplementation with antioxidants can reduce the damage caused by reactive oxygen species and increase the fertilizing capacity of sperm due to improvement in semen parameters. Semen analysis was assessed according to the criteria of the World Health Organization (1999), subfertile men who received folic acid at a dose of 5 mg/day or

7. Effects of supplementation N-Acetylcisteine (NAC) plasmatic on markers of oxidative stress in voleyball players / Efeitos da suplementaÃÃo de N-acetilcisteÃna (NAC) sobre marcadores plasmÃticos de estresse oxidativo em jogadores de voleibol
This study aimed to investigate the effects of an acute dose of NAC as a possible modulator of a large number of markers of oxidative stress and tissue damage in volleyball athletes. Was conducted with 18 young athletes who performed their regular training without the use of antioxidant supplementation, where they underwent an intense training session of vol

8. Alterações dos fatores de risco cardiovasculares segundo o consumo de óleo de coco.
Cardiovascular disease (CVD) represents the principal cause of mortality in this country and the prevalence is increasing amongst the lower socioeconomic classes. Modifiable risk factors, that can be removed or controlled by means of changes of lifestyle, are distinguished amongst the variables related to this occurence. Of these factors, tobacco smoking, se

9. Análise de biomarcadores de balanço redox em portadores de hipertensão arterial primária: uma avaliação segundo técnicas bioquímicas, cromatográficas e espectrofotométricas. / Analysis of redox imbalance biomarkers in hypertenses: evaluation based upon biochemical, chromatographic and spectrophotometric techniques.
The participation of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in systemic arterial hypertension (SAH) has been described in recent papers, which indicate the importance of studying the phenomena that influences the redox environment in blood of patients with high blood pressure (hypertenses), as well as the dietary aspects that could

10. Structural, chemical and biological aspects of antioxidants for strategies against metal and metalloid exposure
Oxidative stress contributes to the pathophysiology of exposure to heavy metals/metalloid. Beneficial renal effects of some medications, such as chelation therapy depend at least partially on the ability to alleviate oxidative stress. The administration of various natural or synthetic antioxidants has been shown to be of benefit in the prevention and attenua

12. Vitamin E prevents oxidative modification of brain and lymphocyte band 3 proteins during aging.
Antioxidants may play an important role in preventing free radical damage associated with aging by interfering directly in the generation of radicals or by scavenging them. We investigated the effects of a high vitamin E and/or a high beta-carotene diet on aging of the anion transporter, band 3, in lymphocytes and brain. The band 3 proteins function as anion
