Nitric oxide synthases from photosynthetic organisms improve growth and confer nitrosative stress tolerance in E. coli. Insights on the pterin cofactor
(Academic Press Inc Elsevier Science, 2021-03)
Nitric oxide synthase (NOS) synthesizes NO from the substrate L-arginine (Arg). NOS with distinct biochemical properties were characterized from two photosynthetic microorganisms, the unicellular algae Ostreococcus tauri ...
Brain oxidative stress in the chronic overloads of iron and copper in rats.
(Elsevier Science Inc, 2019-12)
Male rats of 80–90 g that were fed 42 days with a commercial rodent diet of 2780 kcal/100 g and received chronic overloads of either Fe(II) or Cu(II) in the drinking water. The two metals produced brain oxidative stress ...
Plasmon-induced oxidative stress and macromolecular damage in pathogenic bacteria
(Royal Society of Chemistry, 2016-10)
The inactivation mechanism of bacterial growth by Photodynamic Antibacterial Chemotherapy (PACT) employing gold nanoparticles and gold core/silver shell aspartame stabilized bimetallic nanoparticles was studied. Reactive ...
Oxidative Stress and Genomic Damage Induced In Vitro in Human Peripheral Blood by Two Preventive Treatments of Iron Deficiency Anemia
(Humana Press, 2019-08)
Iron deficiency is the most prevalent nutritional deficiency and the main cause of anemia worldwide. Since children aged 6–24 months are among the most vulnerable groups at risk, daily supplementation with ferrous sulfate ...
Oxidative status and stress during highly energetic life-history stages of Chinstrap Penguins: breeding versus molting
(Wiley Blackwell Publishing, Inc, 2019-06)
Life-history stages such as reproduction and molt are energetically costly. Reproductive costs include those associated not only with offspring production, but also protecting and provisioning young. Costs typically ...
Oxidative balance in follicular fluid of art patients of advanced maternal age and blastocyst formation
(Sociedade Brasileira de Reprodução Humana, 2020)
Objective: To evaluate the follicular fluid oxidative balance of infertile patients of advanced-maternal-age and the correlation between oxidative imbalance in the follicu-lar fluid and the embryological outcomes. Methods: ...
The production of nitric oxide in the coeliac ganglion modulates the effect of cholinergic neurotransmission on the rat ovary during the preovulatory period
(Academic Press Inc Elsevier Science, 2018-05)
The aim of the present work was to investigate whether the nitric oxide produced by the nitric oxide/nitric oxide synthase (NO/NOS) system present in the coeliac ganglion modulates the effects of cholinergic innervation ...
Evaluation of total antioxidant activity and oxidative stress in seminal plasma from dogs supplemented with fish oil and vitamin E
(Royan Institute, 2021-01)
Background: We evaluated the effect of fish oil (FO) and FO in addition to vitamin E (VE) supplementation on total antioxidant activity of dog seminal plasma, and further assessed oxidative stress. Additionally, we measured ...
The effect of nitric oxide on Heme Oxygenase gene expression in soybean leaves
(Springer, 2007-10)
Heme oxygenase (HO, EC 1.14.99.3) catalyzes the oxidative conversion of heme to biliverdin IXalpha with the concomitant release of carbon monoxide and iron. Recently, HO has been involved in the protection against oxidative ...
