BACKGROUND Cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) is a recently described method of post processing routine cine acquisitions which aims to provide quantitative measurements of circumferentially and radially directed ventricular wall strain. Inter-study reproducibility is important for serial assessments however has not been defined for CMR-FT. METHODS 16 healt...

Near-infrared spectroscopy (NIRS)-derived measures of tissue oxygen saturation (StO2) have been recently shown to significantly correlate with the widely used method for noninvasively assessing vascular endothelial function, flow-mediated dilation (FMD). The purpose of this study was to examine the intraday and interday reliability of the reperfusion slope of StO2 (slope 2 StO2) and compare it ...

PURPOSE The purpose of this study was to determine the within-session variability and between-session repeatability of spectral Fourier-domain optical coherence tomography (Doppler FD-OCT) Doppler retinal blood flow measurements in young and elderly subjects. METHODS Doppler FD-OCT blood flow was measured using the RTVue system. One eye of each of 20 healthy young (24.7 ± 2.7 years) and 16 he...

PURPOSE To assess the repeatability of the Galilei dual Scheimpflug analyzer (GDSA) in anterior segment examination. METHODS Fifty-two eyes from 52 healthy volunteers were prospectively and consecutively recruited. Anatomic, axial, refractive, and instantaneous parameters were measured with GDSA to provide a complete characterization of the anterior segment. Repeatability was assessed calcula...

We describe the electrochemical determination of oxidative damaged DNA by using a nanocarbon film electrode combined with a high performance liquid chromatography (HPLC) system. The nanocarbon film was formed by employing the electron cyclotron resonance sputtering method, and has a nano-crystalline sp(2) and sp(3) mixed bond structure with an atomically flat surface. This film electrode provid...
