To investigate the effects of probucol on the treatment of spinal cord injury in rat, 80 rats were randomly divided into two groups of 40: a group treated with probucol and a control group. Allen’s method was used to establish a rat model of spinal cord injury. After establishment, probucol (500 mg·kg-1·day-1) was intraperitoneally injected into the treatment group ... more
Dietary zinc may attenuate heat-induced testicular oxidative stress in mice via up-regulation of Cu-Zn SOD
Zinc (Zn) is important for male mammalian reproduction. In this study, we sought to clarify the role of Zn in heat-induced testicular damage in mice. Eighteen mice were divided into either control (con), heat (heat) and heat plus Zn (H+Zn) treatment groups, and fed diets containing 60 (con and heat groups) or 300 (H+Zn group) mg/kg Zn sulfate for one month. Mice in the con group were then ... more
β-amyloid peptides (Aβs) can exert neurotoxic effects through induction of oxidative damage, whereas lipoic acid (LA), a powerful antioxidant, can alleviate oxidative damage. In this study, we explored the effect and mechanism of action of LA on beta-amyloid-intoxicated C6 glioma cells. Cells were randomly divided into three groups: control (vehicle), Aβ, and LA + Aβ. The LA + Aβ ... more
Mechanisms of antioxidant defense in the state of post-hypoxia in Phrynops geoffroanus (Testudines: Chelidae)
Relationship between lymphocyte DNA fragmentation and dose of iron oxide (FeO) and silicon oxide (SiO) nanoparticles.
At present, the use of nanoparticles is a controversial topic, especially when analyzing their effects in human tissues. Nanoparticles (NPs) can cause oxidative stress by increasing membrane lipids peroxidation and reactive oxygen species, and decreasing intracellular glutathione. Oxidative stress plays an important role in cell signaling and inflammatory responses. It can result in ... more
Effects of mutant TDP-43 on the Nrf2/ARE pathway and protein expression of MafK and JDP2 in NSC-34 cells.
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects motor neurons and lacks an effective treatment. The disease pathogenesis has not been clarified at present. Pathological transactive response DNA-binding protein 43 (TDP-43) plays an important role in the pathogenesis of ALS. Nuclear translocation of nuclear factor erythroid 2 (NF-E2)-related factor 2 (Nrf2) is ... more
We evaluated the association of glutathione S-transferase polymorphisms (GSTT1 and GSTM1) and oxidative stress biomarkers in patients with schizophrenia. A total of 162 subjects were studied: 53 had schizophrenia (Total Study Group-TSG), and 109 without the disorder (Total Control Group-TCG). To analyze oxidative stress, TSG was distributed into ... more
Val16Ala-SOD2 polymorphism modulates hypothalamic-pituitary-adrenal axis molecules and BDNF levels in healthy adults under no psychological stress
Chronic psychological stress alters the hypothalamic–pituitary–adrenal axis (HPA-axis), triggering chronic oxidative-inflammatory states that are associated with physical and psychiatric conditions. However, it is not clear if basal oxidative-inflammatory states triggered by genetic variation affect the HPA-axis by altering cortisol, adrenocorticotropic hormone ( ... more
