OBJECTIVE Tongxinluo (TXL) has been shown to decrease myocardial necrosis after ischemia/reperfusion (I/R) by simulating ischemia preconditioning (IPC). However, the core mechanism of TXL remains unclear. This study was designed to investigate the key targets of TXL against I/R injury (IRI) among the cardiac structure-function network. MATERIALS AND METHODS To evaluate the severity of lethal ...

A stability indicating High-Performance Liquid Chromatography (HPLC) method wasvalidated and used to study the degradation of cetirizine dihydrochloride in acidic and oxidativeconditions. The separation was carried out on a Symmetry C18 column and a mixture of 50 mMKH2PO4 and acetonitrile (60:40 v/v, pH = 3.5) was used as the mobile phase. The method waslinear over the range of 1-20 μg/mL of ce...

local information about tillage intensity and ground residue coverage is useful for policies in agricultural extension, tillage implement design and upgrading management methods. the current methods for assessing crop residue coverage and tillage intensity such as residue weighing methods, line-transect and photo comparison methods are tedious and time-consuming. the present study was devoted t...

Introduction: The ability to image tumour hypoxia and evaluate oxygenation changes in response to treatment using R2* is a powerful yet underexplored tool in breast cancer in humans [1]. This study evaluates the relationship between baseline histology and dynamic contrast enhanced (DCE) and dynamic susceptibility enhanced (DSC) MRI parameters with R2* in breast cancer. The role of R2* as an ima...

To the Editor: Obuchowski et al. (1 ) recently reviewed the uses and misuses of ROC curves and explained, in simple terms, some sophisticated solutions to frequent problems, thereby popularizing tools described elsewhere, notably in the book coauthored by Nancy Obuchowski (2 ). What prompts me to comment on this careful and timely review are two fundamental questions: What properties should an ...

There is a need to develop indicators of mangrove condition using remotely sensed data. However, remote estimation of leaf and canopy biochemical properties and vegetation condition remains challenging. In this paper, we (i) tested the performance of selected hyperspectral and broad band indices to predict chlorophyll concentration (CC) on mangrove leaves and (ii) showed the potential of Landsa...

BACKGROUND To examine the association of anthropometry indices with gout and to compare the performance of indices to predict gout in Taiwanese men. METHODS There were 1443 male subjects aged more than 20 years who participated in the Nutrition and Health Survey in Taiwan (NAHSIT, 1993-1996). Anthropometric evaluation consisted of weight, height, hip and waist circumference (WC) with later bo...

OBJECTIVE To compare the accuracy of 4 different indices of cardiac risk currently used for predicting perioperative cardiac complications. METHODS We studied 119 patients at a university-affiliated hospital whose cardiac assessment had been required for noncardiac surgery. Predictive factors of high risk for perioperative cardiac complications were assessed through clinical history and physi...
