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
Growing concern for public health and food safety has prompted a special interest in developing nutritional strategies for removing waterborne and foodborne pathogens, including Salmonella. Strong links between manganese (Mn) and intestinal barrier or immune function hint that dietary Mn
The aim of this study was to investigate the expression pattern of manganese superoxide dismutase (MnSOD) in relation to inflammatory factors in ulcerative colitis (UC) and characterize this enzyme as a newly identified biomarker potentially linked to disease pathogenesis of UC. MnSOD expression was
Chronic exposure to manganese (Mn) produces a neurodegenerative disorder affecting the basal ganglia characterized by reactive gliosis and expression of neuroinflammatory genes including inducible nitric oxide synthase (NOS2). Induction of NOS2 in glial cells causes overproduction of nitric oxide
Excessive exposure to manganese (Mn) by inhalation can induce psychosis and Parkinsonism. The clinical manifestations of Mn neurotoxicity have been related to numerous physiological and cellular processes, most notably dopamine depletion. However, few studies have explored the molecular events that
Steady-state mRNA levels and immunoreactive protein for manganese-containing superoxide dismutase (MnSOD) were assayed in rat lungs after subchronic inhalation of the fibrogenic silicon dioxide, cristobalite, or preparations of titanium dioxide (TiO2) of different inflammatory and fibrogenic
Intestinal mucosal immune components and mRNA levels of inflammatory cytokines, tight junction proteins, antioxidant enzymes and related signalling molecules in young grass carp (Ctenopharyngodon idellus) under dietary manganese (Mn) deficiency or excess were investigated. Fish were fed the diets
Manganese(II) complexes with the non-steroidal anti-inflammatory drug tolfenamic acid (Htolf) with the nitrogen-donor heterocyclic ligands 1,10-phenanthroline (phen), pyridine (py), or 2,2'-bipyridylamine (bipyam) and/or the oxygen-donor ligands H2O or N,N-dimethylformamide (DMF) have been
In the present contribution, the biological properties of four manganese complexes with the non-steroidal anti-inflammatory drugs sodium diclofenac (Nadicl) or indomethacin (Hindo) in the presence or absence of salicylaldoxime (Η2sao), i.e. [Μn6(O)2(dicl)2(sao)6(CH3OH)6] 1,
Manganese (II), a transition metal, causes pulmonary inflammation upon environmental or occupational inhalation in excess. We investigated a potential molecular mechanism underlying manganese-induced pulmonary inflammation. Manganese (II) delayed HIF-1alpha protein disappearance, which occurred by
The present study investigated the individual and combined impact of organophosphorus pesticide chlorpyrifos (CPF) and manganese (Mn), a naturally occurring trace metal, on hepatorenal function in adult rats. The four experimental groups namely control, CPF alone (5 mg/kg), Mn alone (10 mg/kg) and
Regulation of gene expression by non-coding RNAs, such as microRNAs (miRNAs), is increasingly being examined in a variety of disciplines. Here we evaluated changes in miRNA expression following metallic nanoparticle (NP) exposure in a mouse neuronal co-culture model. Exposure to manganese (Mn) NPs
To examine the association between manganese intake and the risk of type 2 diabetes in postmenopausal women and determine whether this association is mediated by circulating markers of inflammation.We included 84,285 postmenopausal women without a history BACKGROUND
Intratracheal injection of manganese superoxide dismutase-plasmid/liposome (MnSOD-PL) prior to single fraction or fractionated irradiation of C57BL/6J mouse lung has been demonstrated to protect the lung from irradiation-induced damage.
METHODS
To determine whether irradiation-induced
In this study, we topically administered two antioxidant compounds, the manganese-porphyrin-derivatives BMX-001 and BMX-010, in a mouse model of allergic dermatitis and compared the efficacy for reduction of itch and inflammation. In vitro effects of BMX-001 and BMX-010 on keratinocytes, bone marrow
