Increased plasma creatine kinase-myoglobin (CK-MB) occurs in patients with acute myocardial infarction (AMI), but its underlying relationship with cytosolic phospholipase A2 (cPLA2) is poorly understood. In the present study we sought to determine cPLA2 activation and its relationship with plasma and myocardial CK-MB level and membrane phospholipids (PLs)(More)
BACKGROUND AND AIMS Group IIa secretory phospholipase A2 (sPLA2 IIa) induces atherosclerosis by altering systemic lipoprotein mechanism. The aim of this study was to investigate the expression and localization of sPLA2 IIa in atherosclerosis of rat aorta, myocardium and visceral adipose tissue (VAT) and to explore the effect of simvastatin on sPLA2 IIa(More)
The propagation of oceanic mesoscale signals in the South China Sea (SCS) is mapped from satellite altimetric observations and an eddy-resolving global ocean model by using the maximum cross-correlation (MCC) method. Significant mesoscale signals propagate along two major bands of high variability. The northern band is located west of the Luzon Strait,(More)
The objective of this study was to evaluate the electrophysiologic characteristics of Crista terminalis (CT) and their implication in the pathogenesis of atrial tachycardia in rabbits. For this purpose, 27 New Zealand rabbits were used. Using standard glass microelectrode technique, cellular action potentials (APs) of CT and pectinate muscle (PM) were(More)
With the modeling technology of Petri nets-based, task logics are described in products collaborative design. With boundedness, the coverability tree algorithm of Petri net is designed. On this basis, corresponding Markov chain is constructed; the algorithm of analysis performance of stochastic Petri net is provided. Through the case, the utilization ratio(More)
Basing on the analysis of the studying situation of current routing protocol , this thesis presents a SD-Anycast protocol algorithm, and the routing principle and measure parameter of the protocol is given. By designing packet header, routing maintaining and node dealing modules, it implements this protocol in NS2. Lastly, some quantificational experiments(More)
Following the theory of linear piezoelectricity, we analyzed propagation of guided waves in layered piezoelectric structure. The pattern is a piezoelectric plate sandwiched between two piezoelectric half spaces. The waves propagate near intermediate plate. From this, we get precise dispersion relation which can be changed into to piezoelectric surface(More)
This study was designed to investigate whether administration of digitalis could improve mechanical function of left atrial appendage (LAA) and left atrium prospectively in patients with atrial stunning. Fifty-four consecutive patients in whom atrial stunning was observed immediately after cardioversion of chronic atrial fibrillation (AF) were randomized(More)
