NF-κB is a reduction-oxidation-sensitive transcription factor that plays a key role in regulating the immune response. In these studies, we intended to investigate the role of mitochondrial-derived reactive oxygen species in regulating NF-κB activation by studying transgenic mice that overexpress

The aim of the present study was to evaluate the possibility to modulate the early inflammatory response in vitro by coating titanium surfaces with candidate proinflammatory (fibrinogen coated turned titanium "Fib") and antiinflammatory proteins (catalase on top of fibrinogen coated turned titanium

BACKGROUND Human immune cells generate large amounts of reactive oxygen species (ROS) throughout the respiratory burst that occurs during inflammation. In inflammatory bowel diseases, a sustained and abnormal activation of the immune system results in oxidative stress in the digestive tract and in a

This study was conducted to quantify the effect of systemic Catalase, a hydrogen peroxide scavenger, on villous microcirculation in the inflamed small intestine of the rat. Intestinal inflammation was induced with s.c. application of Indomethacin. Intravital fluorescence microscopy and FITC-labeled

Inflammatory bowel disease (IBD) is an inflammatory disorder of the digestive tract reported to be primarily caused by oxidative stress. In this study, alginate encapsulated nanoceramic carriers were designed to deliver acid labile antioxidant enzyme catalase orally. Complete system was

Several in vitro studies suggest the involvement of active oxygen metabolites in cell damage caused by asbestos. To determine if lung injury, inflammation, and asbestosis could be inhibited in vivo in a rapid-onset, inhalation model of disease, a novel method of chronic administration of antioxidant

Catalase, which can decompose H2O2, has recently been found to generate unspecified reactive oxygen species (ROS) as a result of ultraviolet B (UVB) irradiation. Many proteins, hemes, and iron compounds were first tested to determine that this ROS generation was unique to catalase and immunoglobulin

Influenza A virus pandemics and emerging antiviral resistance highlight the urgent need for novel generic pharmacological strategies that reduce both viral replication and inflammation of the lung. We have previously investigated the therapeutic efficacy of recombinant human catalase (rhCAT) against

BACKGROUND Superoxide dismutase (SOD) and catalase are anti-oxidant enzymes potentially used by the bacteria to neutralize macrophage microbicidal molecules such as hydrogen peroxide (H2O2). OBJECTIVE To investigate contribution of bacterial anti-oxidant enzymes in intracellular survival of

Lotus seed has long been used in traditional medicine and cuisine. In this study, lotus seed protein (LSP) was isolated and evaluated its anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. LSP isolate (LSPI) treatment in LPS-stimulated RAW264.7 macrophages resulted

Intrinsically integrating precise diagnosis, effective therapy, and self-anti-inflammatory action into a single nanoparticle is attractive for tumor treatment and future clinical application, but still remains a great challenge. In this study, bovine serum albumin-iridium oxide nanoparticles

Reactive oxygen species (ROS) produced by activated microglia are deleterious to neurons. In this study, we studied the effect of Mn(III)tetrakis(1-methyl-4-pyridyl)porphyrin (MnTMPyP), a superoxide dismutase/catalase mimetic, on the lipopolysaccharide (LPS)-induced degeneration of dopaminergic

Nuclear factor-kappaB (NF-kappaB) is a transcription factor that plays crucial roles in inflammation, immunity, cell proliferation, and apoptosis. Until now, there have been few studies of NF-kappaB activation in whole animals because of experimental difficulties. Here, we show that mice receiving a

UNASSIGNED Some lactobacilli, which possess superoxide dismutase-like activity and catalase activity naturally, have strong antioxidative properties. The aim of this study was to identify such strains and check which of them play a crucial role in alleviating intestinal inflammation. UNASSIGNED We

OBJECTIVE The purpose of this study was to evaluate the influence of oxygen free radical scavengers on periodontal inflammation and healing process. METHODS Experimental periodontitis was induced by elastic ligatures around premolars (P2, P3, P4) and 1st molars (M1) in the upper and lower jaws of 15
