Biochemical aspects of cellular antioxidant systems
(1996)
Aerobic life is characterized by a steady generation of reactive oxygen species balanced by a similar rate of their consumption by antioxidants. To maintain homeostasis, there is a requirement for the continuous regeneration ...
In utero exposure to air pollution lowers erythrocyte antioxidant defense and decreases weight in adult mice
(ELSEVIER SCIENCE BV, 2011)
In this study, we tested the influence of ambient air pollution on different phases of development of adult mice. With respect to adult weight, the animals that had spent their in utero period exposed to pollution showed ...
In utero exposure to air pollution lowers erythrocyte antioxidant defense and decreases weight in adult mice
(Elsevier B.V., 2011-09-01)
In this study, we tested the influence of ambient air pollution on different phases of development of adult mice. With respect to adult weight, the animals that had spent their in utero period exposed to pollution showed ...
Saxitoxin group toxins accumulation induces antioxidant responses in tissues of mytilus chilensis, ameghinomya antiqua, and concholepas concholepas during a bloom of alexandrium pacificum
(MDPI, 2022)
Saxitoxin (STX) group toxins consist of a set of analogues which are produced by harmful algal blooms (HABs). During a HAB, filter-feeding marine organisms accumulate the dinoflagellates and concentrate the toxins in the ...
Effects of elderflower extract enriched with polyphenols on antioxidant defense of salmon leukocytes
(Elsevier, 2021)
Background: In fish farming, the plant extracts containing antioxidant compounds have been added to
the diet for enhancing pathogen resistance. In vitro studies evaluating the antioxidant effect of herbal
extracts on ...
Antioxidant enzymatic defense in salivary glands of streptozotocin-induced diabetic rats: a temporal study
(JOHN WILEY & SONS LTD, 2010)
Hyperglycemia induces overproduction of superoxide and it is related to diabetic complications. In this study, we analyzed the antioxidant enzymatic defense and the lipid peroxidation of rat salivary glands in six different ...
The immune system is limited by oxidative stress: dietary selenium promotes optimal antioxidative status and greatest immune defense in pacu Piaractus mesopotamicus
(Elsevier B. V., 2015)
Reactive oxygen species (ROS) are reactive molecules containing oxygen, that form as byproducts of aerobic metabolism, including immune system processes. Too much ROS may cause oxidative stress. In this study, we examined ...
Antioxidant defenses, longevity and ecophysiology of South American bats
(Elsevier Science Inc., 2007-12)
Microchiropteran bats sustain very high oxygen consumption rates when active, but they also exhibit drastic daily drops in oxygen consumption when torpid. In addition, bats are also characterized by an extraordinary longevity ...
Effects of Mate Tea (Ilex paraguariensis) Ingestion on mRNA Expression of Antioxidant Enzymes, Lipid Peroxidation, and Total Antioxidant Status in Healthy Young Women
(AMER CHEMICAL SOC, 2009)
The antioxidant activity of mate tea, the roasted product derived from yerba mate (Ilex paraguarienis), was observed in vitro and in animal models, but studies in humans are lacking. The aim of this study was to investigate ...
Antioxidant defense in rat brain regions after developmental lead exposure
(Elsevier B.V., 2001-12-14)
Oxidative stress is considered a possible molecular mechanism involved in Pb neurotoxicity. Considering the vulnerability of the developing brain to Pb neurotoxicity, this study was carried out to investigate the effects ...
