Abstract Background and Purpose Membranous nephropathy (MN) is an immune‐mediated glomerular disease in adults. Antibody‐ antigen‐bonding mechanisms have been largely clarified, but the subepithelium immune complex deposition‐mediated downstream molecular are currently unresolved. Increasing evidence has suggested that gut microbiota contribute to MN pathogenesis. Experimental Approach In this study, we identified alterations faecal serum metabolites mediate aryl hydrocarbon receptor (AhR)...

Epidermal growth factor receptor (EGF-R) is an important target in anticancer therapy. Here we report how a novel EGF-R peptide ligand (D4: Leu-Ala-Arg-Leu-Leu-Thr) identified using computer-aided design approach from virtual library of putative binding peptides by screening against the X-ray crystal structure silico and vitro. The selected conjugated with polyethylene glycol (PEG) lipid, lipid moiety peptide-PEG-lipid conjugate inserted into liposome membranes postmodification process. D4...

ABSTRACT The increasing use of ceftazidime-avibactam has led to the emergence a wide range ceftazidime-avibactam-resistant bla KPC-2 variants. Particularly, conventional carbapenemase phenotypic assay exhibited high false-negative rate for In this study, three colloidal gold immunoassays, including Gold Mountainriver CGI test, Dynamiker test and NG-Test CARBA5, GeneXpert Carba-R, were used detect presence its various variants in 42 Klebsiella pneumoniae strains. These strains covered (13/42)...

Comparison of ex-vivo soft tissue measurements using the GE/Lunar pencil (DPX-L; Co., Madison, WI) and fan beam (Prodigy dual-energy X-ray absorptiometers (DXA) Co.).Intra-instrument reliability was assessed by repeatedly scanning phantoms for lean (water) fat (methanol) one DPX-L two identical Prodigy DXAs at fast, medium, slow scan modes. For each machine, 10 scans phantom were performed speed. The number per instrument totaled 60. Data analyzed ANOVA to ascertain whether speed affected...

Abstract Background MicroRNAs (miRNAs) have been identified as important participants in the development of atherosclerosis (AS). The present study explored role miR-128-3p dysfunction vascular smooth muscle cells (VSMCs) and underlying mechanism. Methods Human VSMCs ApoE knockout (ApoE −/− ) C57BL/6J mice were used to establish AS cell animal models, respectively. Expression levels miR-128-3p, forkhead box O4 (FOXO4) matrix metallopeptidase 9 (MMP9) detected using qRT-PCR Western blot,...

The muscarinic acetylcholine receptor subtype M3 (CHRM3) gene is expressed in islet beta-cells and has a role stimulating insulin secretion; therefore, CHRM3 was analyzed as candidate for type 2 diabetes Pima Indians. Ten variants were genotyped family-based sample (n = 1,037), 1 variant (rs3738435) located the 5' untranslated region of an alternative transcript found to be modestly associated with both early-onset acute response small subset these subjects. To better assess whether this...

4-pentylphenol (PP) and 3-methyl-4-nitrophenol (PNMC), two important components of vehicle emissions, have been shown to confer toxicity in splenocytes. Certain natural products, such as those derived from walnuts, exhibit a range antioxidative, antitumor, anti-inflammatory properties. Here, we investigated the effects walnut polyphenol extract (WPE) on immunotoxicity induced by PP PNMC murine splenic lymphocytes. Treatment with WPE was significantly enhance proliferation splenocytes exposed...

Breast cancer is one of the leading causes deaths in female worldwide. Doxorubicin represents most common chemotherapy for breast cancer, whereas side effects and development resistance impede its effect on chemotherapy. Nicotinamide (NAM), serves as sirtuins' inhibitor, effectively suppressing various types cancer. However, NAM drug are need to be fully investigated.Breast doxorubicin-resistant cells MCF-7/ADR doxorubicin-sensitive MCF-7 were applied this study. Cell proliferation was...
