PURPOSE To measure levels of high-mobility group box -1 (HMGB1) and soluble receptor for advanced glycation end products (sRAGE) in the vitreous fluid from patients with proliferative diabetic retinopathy (PDR) and to correlate their levels with clinical disease activity and the levels of the inflammatory biomarkers monocyte chemoattractant protein-1(More)
Oxidative stress leads to complex biochemical alterations, and has been implicated in the progressive loss of learning and memory. Supplementing and boosting the endogenous antioxidant defense system could impede the progression of various types of neurodegeneration. In the present study, we have investigated the neuroprotective efficacy of a low-dose(More)
The purpose of the current study was to evaluate the effect of 12/15-lipoxygenase (12/15-LOX) metabolites on retinal endothelial cell (REC) barrier function. FITC-dextran flux across the REC monolayers and electrical cell-substrate impedance sensing (ECIS) were used to evaluate the effect of 12- and 15-hydroxyeicosatetreanoic acids (HETE) on REC(More)
Traumatic optic neuropathy (TON) is associated with apoptosis of retinal ganglion cells. Local productions of reactive oxygen species and inflammatory mediators from activated microglial cells have been hypothesized to underlie apoptotic processes. We previously demonstrated that the anti-inflammatory effect of adenosine, through A2A receptor activation had(More)
PURPOSE The purpose of this study was to evaluate caspase-14 expression in the retina under normal and diabetic conditions, and to determine whether caspase-14 contributes to retinal microvascular cell death under high glucose conditions. METHODS Quantitative real-time polymerase chain reaction and western blot analysis were used to evaluate caspase-14(More)
Restoration of blood flow to an ischemic brain region is associated with generation of reactive oxygen species (ROS) with consequent reperfusion injury. ROS cause lipid peroxidation, protein oxidation, and DNA damage, all of which are deleterious to cells. So diminishing the production of free radicals and scavenging them may be a successful therapeutic(More)
Diabetic retinopathy (DR) is one of the most common complications of diabetes mellitus. Vision loss in DR principally occurs due to breakdown of the blood-retinal barrier (BRB), leading to macular edema, retinal detachment and inner retinal and vitreous hemorrhage. Several growth factors have been shown to play crucial role in the development of these(More)
Natural antioxidants have shown a remarkable reduction in oxidative stress due to excess formation of reactive oxygen species by enhancing antioxidant mechanism in the neurodegenerative disorders. Sesame seed oil (SO) is one of the most important edible oil in India as well as in Asian countries and has potent antioxidant properties thus the present study(More)
The standardized extract of Bacopa monniera (BM) is a complex mixture of ingredients with a uniquely wide spectrum of neuropharmacological influences upon the central nervous system including enhanced learning and memory with known antioxidant potential and protection of the brain from oxidative damage. The present study demonstrates the therapeutic(More)
Stroke is a severe neurological disorder characterized by the abrupt loss of blood circulation into the brain resulting into wide ranging brain and behavior abnormalities. The present study was designed to evaluate molecular mechanism by which sesamin (SES) induces neuroprotection in mouse model of ischemic stroke. The results of this study demonstrate that(More)
