Plasma antioxidants and glutamine supplementation in HIV
(2015-01-01)
HIV+ patients present higher plasma levels of pro-oxidant and lower antioxidant markers irrespective of their nutritional status and the presence of HAART [1]. The presence of HAART showed some beneficial effects on ...
Quercetin ameliorates glucose and lipid metabolism and improves antioxidant status in postnatally monosodium glutamate-induced metabolic alterations
(Pergamon-Elsevier B.V. Ltd, 2012-10-01)
We reported the effects of quercetin on metabolic and hormonal profile as well as serum antioxidant activities in a model of MSG (monosodium glutamate)-induced obesity. Rats were divided into 4 groups: MSG group, submitted ...
Serum Antioxidant Associations with Metabolic Characteristics in Metabolically Healthy and Unhealthy Adolescents with Severe Obesity: An Observational Study
(Mdpi, 2018)
Considering the inadequacy of some antioxidant nutrients in severely obese adolescents, this study aimed to assess the relationship between antioxidant micronutrients status and metabolic syndrome components in metabolically ...
Changes in photosynthesis and antioxidant metabolism of cotton (Gossypium hirsutum L.) plants in response to manganese stress
(2019-01-01)
This study aimed to assess the physiological and biochemical responses of cotton plants to manganese (Mn2+) nutrition. Four cotton genotypes (G1–TMG 47; G2–FM 975 WS; G3–TMG 11 WS and G4–IMA 8405 GLT) were grown in nutrient ...
Impact of foliar nickel application on urease activity, antioxidant metabolism and control of powdery mildew (Microsphaera diffusa) in soybean plants
(2018-09-01)
Nickel (Ni) is a cofactor for urease, an enzyme that breaks down urea into ammonia and carbon dioxide. This study aimed to evaluate the physiological impact of Ni on urea, antioxidant metabolism and powdery mildew severity ...
Impaired antioxidant capacity causes a disruption of metabolic homeostasis in sickle erythrocytes
(2019-09-01)
This study examined particularly relevant redox pathways such as glycolysis, pentose phosphate pathway (PPP), metHb reductase and nucleotide metabolism, in order to better address how sickle cells deal with redox metabolism ...
Photoprotection and antioxidative metabolism in Ulva lactuca exposed to coastal oceanic acidification scenarios in the presence of Irgarol
(Elsevier B.V., 2021-01-01)
Anthropogenic changes such as ocean acidification, eutrophication, and the release of hazardous chemicals affect coastal environments and aquatic organisms. We investigated the effects of seawater pH (7.4 and 8.2) isolated ...
Antioxidant Activity of gamma-Oryzanol: A Complex Network of Interactions
(Mdpi Ag, 2016-08-01)
gamma-oryzanol (Orz), a steryl ferulate extracted from rice bran layer, exerts a wide spectrum of biological activities. In addition to its antioxidant activity, Orz is often associated with cholesterol-lowering, ...
