Neuro-oxidative-nitrosative stress in sepsis.
Neuro-oxidative-nitrosative stress may prove the molecular basis underlying brain dysfunction in sepsis. In the current review, we describe how sepsis-induced reactive oxygen and nitrogen species (ROS/RNS) trigger lipid peroxidation chain reactions throughout the cerebrovasculature and surrounding brain parenchyma, due to failure of the local antioxidant systems. ROS/RNS cause structural membra...
متن کاملOxidative and nitrosative stress in acute renal ischemia.
Generation of reactive oxygen species and nitric oxide in hypoxia-reperfusion injury may form a cytotoxic metabolite, peroxynitrite, which is capable of causing lipid peroxidation and DNA damage. This study was designed to examine the contribution of oxidative and nitrosative stress to the renal damage in ischemic acute renal failure (iARF). iARF was initiated in rats by 45-min renal artery cla...
متن کاملEffect of combined oxidative and nitrosative stress on Neisseria meningitidis.
Reactive oxygen and nitrogen species are produced by the human immune system in response to infection. Methods to detoxify these reactive species are vital to the survival of human pathogens, such as Neisseria meningitidis, which is the major aetiological agent of bacterial meningitis. Following activation, macrophages produce superoxide (O(2)(-)), hydrogen peroxide (H(2)O(2)) and nitric oxide ...
متن کاملOxidative and Nitrosative Stress in the Metastatic Microenvironment
Metastases that are resistant to conventional therapies are the main cause of most cancer-related deaths in humans. Tumor cell heterogeneity, which associates with genomic and phenotypic instability, represents a major problem for cancer therapy. Additional factors, such as the attack of immune cells or organ-specific microenvironments, also influence metastatic cell behavior and the response t...
متن کاملProcyanidin B2 Protects Neurons from Oxidative, Nitrosative, and Excitotoxic Stress
The aberrant generation of oxygen and nitrogen free radicals can cause severe damage to key cellular components, resulting in cell apoptosis. Similarly, excitotoxicity leads to protease activation and mitochondrial dysfunction, which subsequently causes cell death. Each of these factors play critical roles in the neuronal cell death underlying various neurodegenerative diseases. Procyanidin B2 ...
