Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants that are toxic, mutagenic, and carcinogenic. We investigated the horseradish peroxidase (HRP)-catalyzed oxidation of PAHs in water containing N,N-dimethylformamide. Four PAHs (anthracene, phenanthrene, pyrene, and fluoranthene) were investigated using single-PAH and mixed-PAH systems.(More)
miR-155 (microRNA-155) is an important noncoding RNA in regulating host inflammatory responses. However, its regulatory role in ocular infection remains unclear. Our study first explored the function of miR-155 in Pseudomonas aeruginosa-induced keratitis, one of the most common sight-threatening ocular diseases. We found that miR-155 expression was enhanced(More)
Primary biliary cirrhosis (PBC) is a progressive autoimmune liver disease in which monocytes/macrophages infiltration and skewed T helper type (Th) 1 and Th17 cell responses participate in the development of the disease. Human peripheral blood monocytes are heterogeneous and can be divided into classical CD14highCD16−, intermediate CD14highCD16+, and(More)
To shed light on the causes of Kaschin-Beck disease, which can be prevented by supplementation of the diet with sodium selenite, the interactions between inorganic selenium compounds (selenite and selenate) and humic/fulvic acid were investigated. Selenate was found to be slowly reduced to selenite by humic acid in acidic solution. Selenite was adsorbed on(More)
The distributions of endophytic bacteria in Alopecurus aequalis Sobol and Oxalis corniculata L. grown in soils contaminated with different levels of polycyclic aromatic hydrocarbons (PAHs) were investigated with polymerase chain reaction followed by denaturing gradient gel electrophoresis technology (PCR-DGGE) and cultivation methods. Twelve types of PAHs,(More)
As a novel family of cell surface receptors, triggering receptors expressed on myeloid cells (TREMs) play an important role in inflammatory responses. However, the role of TREMs in the ocular immune system remains unknown. In this study, we examined the expression and function of TREM-1 in Pseudomonas aeruginosa keratitis, one of the most common(More)
In this work, two groups of experiments have been done by using mice and luminous bacteria. The results show that there exists an antagonism in toxicity between selenium and humic acid (HA) extracted from the drinking water in Kaschin Beck disease regions. In order to study the chemical mechanism of the antagonism, gel filtration and X-ray photoelectron(More)
This is the first investigation of the diversity and distribution of 16S rRNA and phenol monooxygenase (PHE) genes in endophytic and rhizosphere bacteria of plants at sites contaminated with different levels of PAHs. Ten PAHs at concentrations from 34.22 to 55.29 and 45.79 to 97.81 mg·kg(-1) were measured in rhizosphere soils of Alopecurus aequalis Sobol(More)
OBJECTIVE Many CD95-expressing cells don't always undergo apoptosis after stimulation with CD95 ligation. The purpose of this paper is to investigate the role of expression of CD95 (Fas/Apo1) on inflammatory response in fibroblast-like synoviocytes (FLS) obtained from rheumatoid arthritis (RA) and to evaluate the role of phosphatidylinositol 3-kinase(More)
OBJECTIVE To explore the anti-inflammatory effect of triptolide (TPT) by regulating miR-155 in monocytes pre-stimulated by lipopolysaccharide (LPS) from rheumatoid arthritis (RA) patients. METHODS Monocytes were isolated by CD14⁺ magnetic beads from peripheral blood mononuclear cells (PBMCs) of RA and stimulated by LPS for 24 hours. The levels of(More)
