The present paper describes a nonenzymatic chemiresistor sensor based on an azo-polymer and reduced graphene oxide (rGO) as a resistive platform for superoxide radical detection. The sensorial platform was prepared on ...

Objective(s): To investigate the chronopharmacological effects of growth hormone on executive function and the oxidative stress response in rats. Materials and Methods: Fifty male Wistar rats (36-40 weeks old) had ad libitum ...

In this study, novel sensitive and selective hydrogel microstructures to detect superoxide anions released by cancer cells, based on electrochemical biosensors, are proposed. Ferrocene was coupled with superoxide dismutase ...

Paracoccidioidomycosis, a deep mycosis endemic in Latin America, is a chronic granulomatous disease caused by the fungus Paracoccidioides brasiliensis. Phagocytic cells play a critical role against the fungus and several ...

This study sought to determine the chronobiological variations in soluble and cellular components of human breast milk. The material was collected from 36 mothers at three stages of maturity - 3 days (colostrum), 10 days ...

To determine the relation between neutrophil function and the clinical characteristics of systemic lupus erythematosus ( SLE), the superoxide anion (O(2)(-)) production by neutrophils, mediated by Fc gamma R and Fc gamma ...

Reactivity of two new C4-indolyl substituted 1,4-dihydropyridines (1,4-DHPs) toward superoxide anion (O2-) in dimethylsulfoxide (DMSO) is reported. Reactivity was followed by electrochemical and spectroscopic techniques. ...
