ARDS is a disease process that is characterized by diffuse inflammation in the lung parenchyma. The involvement of inflammatory mediators in ARDS has been the subject of intense investigation, and oxidant-mediated tissue injury is likely to be important in the pathogenesis of ARDS. In response to various inflammatory stimuli, lung endothelial cells, alveolar cells, and airway epithelial cells, ...
Nuclear factor-κB (NF-κB) plays a role in inflammation. However, we recently reported an association between NF-κB and antioxidant enzymes in renal proximal tubules of exercise-trained rats, suggesting its role in antioxidant homeostasis (George L, Lokhandwala MF, Asghar M. Am J Physiol Renal Physiol 297: F1174-F1180, 2009). A direct role of NF-κB in antioxidant homeostasis in renal cells has n...
BACKGROUND/AIM Reactive oxygen species play an important role in the pathogenesis of acute pancreatitis (AP) in animal models. Data on the oxidant-antioxidant balance in humans are scanty. The present study was undertaken to evaluate the dynamics of changes in the oxidant-antioxidant balance in the early phase of human AP. METHODS 74 consecutive patients with acute biliary pancreatitis (16 wi...
The aim of this study was to investigate the role of redox status in endometriosis and its malignant transformation. A search was conducted between 1990 and 2014 through the English language literature (online MEDLINE PubMed database) using the keywords endometriosis combined with malignant transformation, oxidative stress, and antioxidant defense. In benign endometriosis, autoxidation and Fent...
This article characterised the role of oxidative stress in mediating pathological reactions in the lung and the unique antioxidant defences that the lung possesses. The impact of redox balance in regulating inflammatory and immune reactions were discussed, and the impact of enhancing lung antioxidant capacity in animal models of asthma and chronic obstructive pulmonary disease were characterised.
Background and purpose: Multiple sclerosis (MS) as an autoimmune disease is the most common demyelinating inflammatory disease in young people that affects the central nervous system. Myricitrin (MYR) is known to have antioxidant and neuroprotection effects, so, the current study investigated its effect on cognitive defects in rat models of MS. Materials and methods: In this experimental study...
Plants can maintain growth and reproductive success by sensing changes in the environment and reacting through mechanisms at molecular, cellular, physiological, and developmental levels. Each stress condition prompts a unique response although some overlap between the reactions to abiotic stress (drought, heat, cold, salt or high light) and to biotic stress (pathogens) does occur. A common feat...
