(−)-Epigallocatechin gallate (EGCG) is a major polyphenol component of green tea that has antioxidant activities. Lipopolysaccharide (LPS) induces inflammatory cytokine production and impairs blood–brain barrier (BBB) integrity. We examined the effect of EGCG on LPS-induced expression of the inflammatory cytokines in human cerebral microvascular endothelial(More)
BACKGROUND Treatment of diabetes mellitus with Traditional Chinese Medicine has a long history. The aim of this study is to establish the safety and efficacy of traditional Chinese medicine combined with glibenclamide to treat type 2 diabetes mellitus. METHODS In a controlled, double blind, multicentre non-inferiority trial, 800 patients with(More)
BACKGROUND Opioids exert a profound influence on immunomodulation and enhance HIV infection and replication. However, the mechanism(s) of their action remains to be determined. We thus investigated the impact of morphine on the intracellular innate antiviral immunity. METHODOLOGY/PRINCIPAL FINDINGS Seven-day-cultured macrophages were infected with equal(More)
BACKGROUND Respiratory tract infections (RTIs) represent one of the main health problems in children. Probiotics are viable bacteria that colonize the intestine and affect the host intestinal microbial balance. Accumulating evidence suggests that probiotic consumption may decrease the incidence of or modify RTIs. The authors systematically reviewed data(More)
BACKGROUND Macrophages play critical roles in innate immune response in the liver. Whether macrophages participate in liver innate immunity against HCV replication is poorly understood. OBJECTIVES The aim of this study was to investigate the role of macrophages in liver innate immunity against HCV replication. MATERIALS AND METHODS Freshly isolated(More)
BACKGROUND The main objective of this study was to test Argus II subjects on three real-world functional vision tasks. DESIGN The study was designed to be randomized and prospective. Testing was conducted in a hospital/research laboratory setting at the various participating centres. PARTICIPANTS Twenty eight Argus II subjects, all profoundly blind,(More)
(-)-Epigallocatechin-3-gallate (EGCG), a major polyphenol component of green tea, has recently been identified as an inhibitor of hepatitis C virus (HCV) entry. Here, we examined whether EGCG can enhance hepatocyte-mediated intracellular innate immunity against HCV. HCV dsRNAs (Core, E1-P7, NS-3'NTR and NS5A) induced interferon-λ1 (IFN-λ1) expression in(More)
BACKGROUND The purpose of this analysis is to report the change in quality of life (QoL) after treatment with the Argus II Epiretinal Prosthesis in patients with end-stage retinitis pigmentosa. METHODS The Vision and Quality of Life Index (VisQoL) was used to assess changes in QoL dimensions and overall utility score in a prospective 30-patient single-arm(More)
Type 2 diabetes is associated with reduced risk of prostate cancer and low prostate-specific antigen levels for uncertain reasons. Recently, two studies demonstrated the time course of diabetes with prostate-specific antigen levels, which would be explained by the chronic renal complication. Therefore, we conducted a retrospective study to determine whether(More)
