Para tal, texto recupera e amplia conceitos basilares pesquisa citada; reapresenta dados coletados analis...

Nets, useful topological tools, used to generalize certainconcepts that may only be general enough in the context of metricspaces. In this work we introduce this concept in an $S$-poset, aposet with an action of a posemigroup $S$ on it whichis a very useful structure in computer sciences and interestingfor mathematicians, and give the the concept of $S$-net. Using $S$-nets and itsconvergency we...

Oxidative damage associated with lead in the brain has been proposed as a possible mechanism of lead toxicity. Of the many antioxidant enzymes, phospholipid hydroperoxidase glutathione peroxidase (PHGPx) is known to protect cells from lipid peroxide-mediated damage by catalyzing lipid peroxide reduction. In this study, the effects of lead on the activity and expression of PHGPx mRNA were invest...

BACKGROUND Impact of the pathophysiology of Plasmodium falciparum placental malaria (PM) on the profile of some oxidative stress biomarkers and their relationship with poor pregnancy outcomes in women remain unknown. METHODS Between 2013 and 2014, peripheral blood and placenta tissue from 120 Cameroonian women at delivery were assessed for maternal haemoglobin and, parasitaemia respectively. ...

Recent studies demonstrated that the proanthocyanidins (PA), the polymers of flavan-3-ols, naturally occurring plant metabolites widely available in fruits, vegetables, nuts, seeds, flowers and bark, have anti-inflammatory, anticarcinogenic, anti-allergic, antioxidant and vasodilatory actions. We hypothesized that Viburnum opulus PA (VOPA, Caprifoliaceae), due to activation of multifactorial ga...
