Overproduction of nitric oxide (NO) by inducible NO synthase (iNOS) plays a role in the pathophysiology of septic shock. The depression of cardiac contractility in such situations is mediated by proinflammatory cytokines, including interleukin-1beta (IL-1beta), and tumor necrosis factor-alpha

Septicemia leads to oxidative stress with overproduction of reactive-oxygen species (ROS) and consumption of endogenous antioxidant enzymes. We tested a twofold hypothesis: (1) does oxidative stress (OxS) induced by sepsis acting alone or in concert with augmented inflammatory processes contributes

Antitumour agents such as flavone acetic acid, xanthenone acetic acid (XAA), 5,6-dimethylxanthenone-4-acetic acid and tumour necrosis factor-alpha, following single dose administration to mice with colon 38 adenocarcinomas, induce tumour haemorrhagic necrosis and an elevation in plasma nitrate. The

Astaxanthin is a carotenoid known to have antioxidant and antiinflammatory properties. This study examined if shrimp astaxanthin modulates the production of superoxide (O(-)(2)), nitric oxide (NO), and tumor necrosis factor-α (TNF-α) in rat alveolar macrophages. The oxidative effect was induced by

BACKGROUND Hepatic encephalopathy is a complex neuropsychiatric syndrome. A previous study showed that chronic nitric oxide (NO) inhibition aggravated the severity of encephalopathy in thioacetamide (TAA)-treated rats. The present study investigated the relative contribution of NO synthase (NOS)

BACKGROUND The serum levels of proinflammatory cytokines have been reported to be significantly higher in severe acute pancreatitis compared with mild pancreatitis. Nitric oxide (NO) produced by cytokine-inducible NO synthase might be involved as the mechanisms for the progression of pancreatitis

In the central nervous system (CNS), cytokine-primed microglia play a central role in host's defense against Acanthamoeba castellanii infection. In this study, the effect of recombinant interferon (rIFN)-gamma and Salmonella enterica serovar enteritidis lipopolysaccharide (LPS), both inflammatory

The implication of β-N-methylamino-L-alanine (BMAA) in the development of neurodegenerative diseases worldwide has led to several investigations of the mechanism, or mechanisms, of toxicity of this cyanobacterially produced amino acid. The primary mechanism of toxicity that was identified is
