objective: hexavalent chromium [cr (vi)] compounds are well-known environmental contaminants  generated from industrial processes. several studies have reported the harmful effects of cr (vi) on different organs, however, little is known about neurotoxic effects of cr (vi). the aim of this study is to investigate the toxic effects of cr (vi) on pc12 cells. methods: pc12 cells were cultured foll...

Obesity-associated insulin resistance has long been linked to both increased adipocyte oxidative stress as well as the presence of inflammatory changes in adipose tissue, including the infiltration and activation of tissue-resident macrophages. In order to investigate the connections between obesity-associated oxidative stress in adipocytes and increased inflammation in adipose tissue associate...

It is known that fluoride produces oxidative stress. Inflammation in bone tissue and an impairment of the respiratory chain of liver have been described in treatments with fluoride. Whether the impairment of the respiratory chain and oxidative stress are related is not known. The aim of this work was to study the effects of fluoride on the production of superoxide radical, the function of the r...

Lysosomal and microsomal acid phosphatase activity was estimated in midgut tissue of silkworm larvae, Bombyx mori L. (Lepidoptera: Bombycidae), after induced oxidative stress by D-galactose. The larvae were simultaneously were treated with ethanolic extracts of Bacopa monniera and Lactuca sativa to study their antioxidant properties. Lipid peroxidation and fluorescence was measured to analyze e...

Equine pituitary pars intermedia dysfunction (PPID) is a well-recognized disease in aged horses and ponies, yet the etiology and pathophysiology of this condition remains poorly understood. Immunohistochemistry of formalin-fixed pituitary tissue was used to demonstrate dopaminergic neurodegeneration and oxidative stress in the pars intermedia in horses with PPID. The role of oxidative stress in...

Objective(s): Hyperglycemia promotes oxidative stress that plays a crucial role in the pathogenesis of Diabetic nephropathy (DN). In this study, we investigated the synergism effects of hydroalcoholic extract of Urtica dioica and pioglitazone (PIO) on the prevention of DN in streptozotocin induced-diabetic mice. Materials and Methods: Forty-two mice were divided into six groups as follows: non-...

Background: Acetaminophen (APAP) overdose causes renal and hepatic injury. It is ‎also believed that oxidative stress has a pivotal role in APAP-induced renal injury. ‎Therefore, protective effects of different antioxidants have been examined in APAP-‎induced renal and hepatic toxicity models. Stevia rebadiana is a plant with a high ‎degree of natural antioxidant activity in its leaf extract. T...

Introduction:Severe abdominal aortic constriction above the renal arteries induces arterial hypertension above the stenotic site that is the cause of cardiac hypertrophy. Previous studies have shown that high blood pressure induces myocardial oxidative stress with conflicting results. In the present study, we assessed the effects of acute hypertension on the myocardial oxidative stress an...
