Oxidative stress has emerged as a key component of many diseases that affect the vasculature. Oxidative stress is characterized as a cellular environment where the generation of oxidant molecules overwhelms endogenous anti-oxidant defense mechanisms. NADPH oxidases are a family of enzymes whose primary purpose is generation of reactive oxygen species (oxidant molecules) and therefore are likely...

abstractibn-nubatah is one of the poets of deterioration era who lived at this time so hispoetry has the trace of both the imitation and repetition of the poets of that time. heused a kind of poetic theme in his poems that lacks the privilege and typicality of agood poem because he imitated some poets like emre'al- qays, tarafah ibn al-a’bd,khansa, hassan ibn sabet al-ansary, ka’b ibn ...

It has long been recognized that simultaneous exposure to heat stress and oxidative stress shows a synergistic interaction that reduces organismal fitness, but relatively little is known about the mechanisms underlying this interaction. We investigated the role of molecular stress responses in driving this synergistic interaction using the nematode Caenorhabditis elegans To induce oxidative str...

cognitive deficits have been observed in patients with multiple sclerosis (ms) because of hippocampal insults. oxidative stress plays a key role in the pathophysiology of ms. the aim of this study was to evaluate the effects of crocus sativus l., commonly known as saffron, on learning and memory loss and the induction of oxidative stress in the hippocampus of toxic models of ms. one week after ...

Rationale: Oxidative stress in rostral ventrolateral medulla (RVLM), where sympathetic premotor neurons for the maintenance of neurogenic vasomotor tone are located, contributes to neural mechanisms of hypertension. Emerging evidence suggests that brain-derived neurotrophic factor (BDNF) manifests " nontrophic " actions. Objective: We assessed the hypothesis that BDNF plays an active role in ox...

For decades, oxidative stress has been discussed as a key mechanism of endothelial dysfunction and cardiovascular disease. However, attempts to validate and exploit this hypothesis clinically by supplementing antioxidants have failed. Nevertheless, this does not disprove the oxidative stress hypothesis. As a certain degree of reactive oxygen species (ROS) formation appears to be physiological a...

Abstract: Background: Neuroprotection is one of considerable interest in search novel therapies to improve ischemic brain damage the present scenario. The objective investigation study actions Talinum triangulare cerebral ischemia/reperfusion induced oxidative stress Wistar rats and in-vitro antioxidant actions. Methods: Four different groups adult are selected for where group III IV treated 15...
