Renal interstitial fibrosis is characterized by increased extracellular matrix (ECM) synthesis. Epithelial-mesenchymal transition (EMT) in kidneys is driven by regulated expression of fibrogenic cytokines such as transforming growth factor-beta (TGF-β). Yam, or Dioscorea alata (DA) is an important herb in Chinese medicine widely used for the treatment of(More)
Detection and quantification for hepatitis B virus (HBV) DNA has been an essential tool in the clinical setting. We aimed to assess clinical performance of the RealArt HBV TM PCR (RealArt) assay and the COBAS TaqMan HBV (COBAS) assay. Serum levels of HBV DNA in 146 treatment-naïve chronic HBV (CHB) Taiwanese patients (118 males, 47 HBeAg + ; mean age,(More)
A multi-case study approach was used in this study to investigate how parents and children collaborated with each other when they learned to program in MSWLogo together. Three parent-child pairs were observed directly in a five-day computer camp. Each pair was assigned a total of 33 programming tasks to work on. The observation focused on how parents(More)
Hyperosmolarity plays an essential role in the pathogenesis of diabetic tubular fibrosis. However, the mechanism of the involvement of hyperosmolarity remains unclear. In this study, mannitol was used to evaluate the effects of hyperosmolarity on a renal distal tubule cell line (MDCK). We investigated transforming growth factor-beta receptors and their(More)
Diabetic nephropathy is characterized by early hypertrophy in both glomerular and tubuloepithelial elements. However, no studies to date have established a direct causal link between hyperglycaemia and renal hypertrophy. Our previous studies have found that high glucose does not induce cellular hypertrophy or expression of TGF-beta1 (transforming growth(More)
We evaluated the performance of a hepatitis C virus (HCV) antigen/antibody combination test [Murex HCV Antigen/Antibody Combination Test (Murex Ag/Ab test)] by comparing it with the current third-generation HCV antibody enzyme immunoassay (anti-HCV). A total of 403 serum samples were consecutively collected from four patient groups: healthy controls(More)
Dysregulation of epithelial-to-mesenchymal transition (EMT) may contribute to renal fibrogenesis. Our previous study indicated that bone morphogenetic protein-2 (BMP-2) significantly reversed transforming growth factor (TGF)-β1-induced renal interstitial fibrosis. In this study, we examined the underlying mechanism and elucidate the regulation of EMT(More)
BACKGROUND Hyperglycemia is the most important risk factor in the progression of renal fibrosis in diabetic kidney. Based on previous studies, interleukin-7 (IL-7) may exert antifibrotic activities in pulmonary fibrosis model. However, the role of IL-7 in the pathogenesis of renal tubulointerstitial fibrosis remains unclear. Thus, we hereby elucidate the(More)
BACKGROUND Selection of drug-resistant strains may lead to failure of HBV antiviral therapy. There is little information whether there is detection difference in drug resistant mutations between different viral load assays of HBV. OBJECTIVES This study is aimed to investigate whether there is drug-resistant strains related detection difference between(More)
Albuminuria is indicative of nephropathy. However, little literature has focused on the role of albumin in renal distal tubule fibrosis. We used a well-defined distal tubule cell, Madin-Darby Canine Kidney (MDCK). Proliferation and cytotoxicity were examined. The conditioned supernatant was collected and subjected to ELISA assay for detection of fibronectin(More)
