BACKGROUND Pentoxifylline (PTX) anti-TNF properties are known to exert hepatoprotective effects in various liver injury models. The aim of this study was to investigate whether PTX has beneficial roles in the development of methionine- and choline-deficient-(MCD-) diet-induced NAFLD SD rats in vivo and TNF-α-induced Hep3B cells in vitro. METHODS SD Rats(More)
Research into multifunctional nanoparticles is focused on creating an agent for use in an all-in-one multimodal imaging system that includes diagnostic imaging, drug delivery, and therapeutic monitoring. We designed a new dual-modality tumor-targeting agent with a new tumor-targeting molecule, oleanolic acid (OA), which is derived from a natural compound(More)
Cigarette smoking is known to aggravate Graves' orbitopathy (GO) severity by enhancing adipogenesis. We investigated the effect of quercetin, an antioxidant, on adipocyte differentiation induced by cigarette smoke extract (CSE) in primary cultured orbital fibroblasts (OFs) from GO patients. Freshly prepared CSE was added to the cells and H(2)O(2) was used(More)
Recent epidemiologic studies clearly showed that early intensive glucose control has a legacy effect for preventing diabetic macrovascular complications. However, the cellular and molecular processes by which high glucose leads to macrovascular complications are poorly understood. Vascular smooth muscle cell (VSMC) dysfunction due to high glucose is a(More)
PURPOSE We investigated the therapeutic effect of nontoxic concentrations of tanshinone IIA (TanIIA) from Salvia miltiorrhiza in primary cultures of orbital fibroblasts from Graves' orbitopathy (GO). METHODS The effect of TanIIA on IL-1β-induced proinflammatory cytokine (IL-6, IL-8, MCP-1) expression was determined by real-time PCR. Antioxidant activity(More)
PURPOSE The authors previously reported that quercetin significantly inhibits interleukin (IL)-1β-induced increases of proinflammatory cytokines in cultured primary orbital fibroblasts from Graves' orbitopathy (GO). This study investigated the inhibitory effect of quercetin on inflammation in cultured whole orbital tissue. METHODS Orbital fat tissues from(More)
BACKGROUND The aim of the present study was to investigate the serum levels of endothelial progenitor cells (EPCs) in type 2 diabetic patients without documented ischemic disease and the association between EPCs and atherosclerotic plaque formation in the carotid artery. METHODS AND RESULTS A clinic-based, prospective study of type 2 diabetic patients was(More)
PURPOSE We investigated the effects of quercetin on fibrotic markers and matrix metalloproteinases (MMPs) in primary cells and whole orbital tissues from Graves' orbitopathy (GO). METHODS Orbital fat tissues were harvested from GO for primary cell and tissue cultures during orbital fat decompression. To determine noncytotoxic dose and time of quercetin(More)
Coronary arterial disease (CAD) is common in diabetic patients, and endothelial progenitor cells (EPCs) are considered a surrogate marker for CAD, but controversies regarding this issue still remain. We investigated the potential clinical role of EPCs during coronary screening in asymptomatic type 2 diabetic patients screened with cardiovascular magnetic(More)
We describe a simple method for synthesizing superparamagnetic nanoparticles (SPIONs) as small, stable contrast agents for magnetic resonance imaging (MRI) based on sulfobetaine zwitterionic ligands. SPIONs synthesized by thermal decomposition were coated with zwitterions to impart water dispersibility and high in vivo stability through the nanoemulsion(More)
