SUMMARY: Traumatic injury to the spinal cord results in the delayed dysfunction and neuronal death. Impaired mitochondrial function, generation of reactive oxygen species (ROS), and lipid peroxidation occur soon after traumatic spinal cord injury (SCI), while the activation of compensatory molecules that...

Sedentarism, overweight and malnutrition generate an increase in the production of reactive oxygen species leading to a state of chronic oxidative stress. In patients with type 2 diabetes mellitus, oxidative stress alters pancreatic insulin secretion and the actions of the hormone on target cells, contri...
Abstract Introduction To manage the complications of irradiation of head and neck tissue is a challenging issue for the otolaryngologist. Definitive treatment of these complications is still controversial. Recently, hyperbaric oxygen therapy is promising option for these complications. Objective In thi...

Abstract: Background: Previous studies have shown oxidative stress in pemphigus vulgaris and pemphigus foliaceus, nevertheless, it remains unknown whether a similar response is characteristic of endemic pemphigus foliaceus in Peru. Objectives: To determine the oxidative stress response in endemic pemph...

This article deals with the expression and
distribution of Thioredoxins during perinatal asphyxia, and its roll in the regulation of
the redox system.
Disorders in the gaseous interchange
through the placenta and the fetal lungs,
can lead to what is known as the perinatal
asphyxia (PA). The PA can involv...
Abstract In general, environmental responses at level of populations or communities are preceded by alterations at lower biological levels which can be efficiently detected by the analysis of biomarkers. We analyzed the oxidative biomarkers TBARS and Catalase in Aegla singularis, a freshwater crustacean ...
Abstract Purpose: To investigate the effects of pycnogenol on peritoneal adhesions and additionally to investigate the immunohistochemical effects of free oxygen radicals and reactive lymph nodes detected in the adhesive tissue that was sampled surrounding the cecum on intra-abdominal adhesions. Metho...

Abstract Purpose: To investigate the biochemical, histopathologic, and spermatogenetic changes in the detorsionated testicle after experimental torsion and to study the antioxidant effects of pheniramine maleate and nebivolol. Methods: Twenty-four Sprague-Dawley male rats were divided into 4 groups: G...

Abstract Background and objectives The waste anesthetic gases (WAGs) present in the ambient air of operating rooms (OR), are associated with various occupational hazards. This paper intends to discuss occupational exposure to WAGs and its impact on exposed professionals, with emphasis on genetic damage ...
Estresse oxidativo é um conceito em evolução. Muito mais do que um simples desbalanço entre oxidantes e antioxidantes, representa um desequilíbrio de vias de sinalização celular redox. Sinalização redox envolve a produção de espécies reativas de oxigênio, radicalares e não radicalares, assi...
