BACKGROUND Gadolinium (Gd) Extracellular volume fraction (ECV) by Cardiovascular Magnetic Resonance (CMR) has been proposed as a non-invasive method for assessment of diffuse myocardial fibrosis. Yet only few studies used 3 T CMR to measure ECV, and the accuracy of ECV measurements at 3 T has not been established. Therefore the aims of the present study were to validate measurement of ECV by MO...
PURPOSE The aim of study was to evaluate the cross-link using riboflavin and ultraviolet A (UVA) for improving scleral wound healing. MATERIALS AND METHODS This was an experimental study involving four New Zealand rabbits (eight eyes). Therapy procedure was chosen for the right eye and control procedure for the left one. UVA irradiation of 365 nm with a surface irradiance of 3 mW/cm2 and a ph...
Earlier work from this laboratory showed that abnormal fibroblast phenotypes isolated from fibrotic human lung produce factor(s) capable of inducing apoptosis and necrosis of alveolar epithelial cells in vitro [B. D. Uhal, I. Joshi, A. True, S. Mundle, A. Raza, A. Pardo, and M. Selman. Am. J. Physiol. 269 ( Lung Cell. Mol. Physiol. 13): L819-L828, 1995]. To determine whether epithelial cell dea...
An increased understanding of the reparative process in fetal membrane following surgical techniques may be helpful to decrease the risks to mother and fetus and avoid adverse pregnancy outcomes. The present study discusses histological evaluation of the fetal membrane following open fetal surgery. Chorioamniotic membranes (n=10) were obtained following birth from pregnancies that underwent ope...
AIM To determine if manipulation of dietary advanced glycation end product (AGE), intake affects non-alcoholic fatty liver disease (NAFLD) progression and whether these effects are mediated via RAGE. METHODS Male C57Bl6 mice were fed a high fat, high fructose, high cholesterol (HFHC) diet for 33 wk and compared with animals on normal chow. A third group were given a HFHC diet that was high in...
We report that the dye nile red, 9-diethylamino-5H-benzo[alpha]phenoxazine-5-one, is an excellent vital stain for the detection of intracellular lipid droplets by fluorescence microscopy and flow cytofluorometry. The specificity of the dye for lipid droplets was assessed on cultured aortic smooth muscle cells and on cultured peritoneal macrophages that were incubated with acetylated low density...
BACKGROUND Breast carcinoma in situ (CIS) is classified into ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). DCIS is treated with surgical excision while LCIS can be clinically followed with or without hormonal treatment. Thus, it is critical to distinguish DCIS from LCIS. Immunohistochemical (IHC) staining for E-cadherin is routinely used to differentiate DCIS from LCIS i...
Cold liver preservation in the University of Wisconsin solution (UW) followed by reperfusion alters hepatic parenchyma and extra cellular matrix. In this study we analyzed the benefit of adding either 500 microM Sodium Nitroprusside (NPNa) or 100 microM S-nitrosoglutathione (GSNO) as Nitric Oxide (NO) donors to the UW solution to prevent hepatic injury. Wistar adult rat livers were stored in UW...
BACKGROUND The right ventricular outflow tract (RVOT) is acknowledged to be responsible for arrhythmogenesis in Brugada syndrome (BrS), but the pathophysiology remains controversial. OBJECTIVES This study assessed the substrate underlying BrS at post-mortem and in vivo, and the role for open thoracotomy ablation. METHODS Six whole hearts from male post-mortem cases of unexplained sudden dea...
