Sperm cryopreservation with supplementation of α-tocopherol and ascorbic acid in freezing media increase sperm function and fertility rate in Atlantic salmon (Salmo salar)
(Elsevier B.V., 2018)
© 2018 Elsevier B.V.The use of α-tocopherol and ascorbic acid in freezing medium prevents lipoperoxidation and damage by ROS (reactive oxygen species); however, the effects of these antioxidants in salmonid spermatozoa ...
Correlations between the phenolic compounds and antioxidant activity in the skin and pulp of table grape varietiesCorrelações entre compostos fenólicos e atividade antioxidante em casca e polpa de variedades de uva de mesa
(2018-01-01)
Grapes are considered a major source of phenolic compounds when compared to other vegetables, but the great diversity amongst the cultivars results in fruits with different characteristics of taste and colour, which is ...

Seed priming with ascorbic acid enhances salt tolerance in micro-tom tomato plants by modifying the antioxidant defense system components
(2021-01-01)
Although ascorbic acid (AsA) has been known to improve plant defense system components against salt stressful-conditions, little is known about physiological and biochemical responses of AsA-mediated alleviation of salt ...
Photochemical damage and comparative performance of superoxide dismutase and ascorbate peroxidase in sugarcane leaves exposed to paraquat-induced oxidative stress
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
The physiological responses of sugarcane (Succharion officinarum L.) to oxidative stress induced by methyl viologen (paraquat) were examined with respect to photochemical activity, chlorophyll content, lipid peroxidation ...
Kinetics, subcellular localization, and contribution to parasite virulence of a Trypanosoma cruzi hybrid type A heme peroxidase (TcAPx-CcP)
(National Academy of Sciences, 2017-02)
The Trypanosoma cruzi ascorbate peroxidase is, by sequence analysis, a hybrid type A member of class I heme peroxidases [TcAPx-cytochrome c peroxidase (CcP)], suggesting both ascorbate (Asc) and cytochrome c (Cc) peroxidase ...
Oxidative processes during 'Golden' papaya fruit ripening
(Brazilian Journal of Plant Physiology, 2012)
'Golden' papayas at maturity stage 1 (15% yellow skin) were chosen to study selected oxidative processes, the activity of antioxidant enzymes and lipid peroxidation in storage at 22°C, during the ripening of the fruit. An ...
Sensorial and biochemical parameters of avocado product with addition of α-tocopherol and ascorbic acid
(2012-01-01)
Commercialization of processed avocado is difficult due to darkening of the pulp and sensorial alterations during the storage. The objective of this research was to verify the sensorial parameters, along with polyphenol ...
