Positive evidence from clinical trials has fueled growing acceptance of traditional Chinese medicine (TCM) for the treatment of cardiac diseases; however, little is known about the underlying mechanisms. Here, we investigated the nature and underlying mechanisms of the effects of YiXin-Shu (YXS), an antioxidant-enriched TCM formula, on myocardial(More)
" Cloud-based " Internet services rely on the availability and reliability of managed data centers. Recent events indicate that data centers tend to create centralized points of failure, and providing resilience to large-scale faults remains a significant challenge for both providers and users of cloud in-frastructures. Running data centers also incurs high(More)
A control-plane architecture for supporting advance reservation of dedicated bandwidth channels on a switched network infrastructure is described including the front-end web interface, user and token management scheme, bandwidth scheduler, and signaling daemon. A path computation algorithm for bandwidth scheduling is proposed based on an extension of(More)
We propose a binary decision fusion rule that reaches a global decision on the presence of a target by integrating local decisions made by multiple sensors. Without requiring a priori probability of target presence, the fusion threshold bounds derived using Chebyshev's inequality ensure a higher hit rate and lower false alarm rate compared to the weighted(More)
AIMS To determine the roles of vitamin D receptor (VDR) in ischemia/reperfusion-induced myocardial injury and to investigate the underlying mechanisms involved. RESULTS The endogenous VDR expression was detected in the mouse heart, and myocardial ischemia/reperfusion (MI/R) upregulated VDR expression. Activation of VDR by natural and synthetic agonists(More)
BACKGROUND Studies focused on cell therapy for chronic ischemic heart disease (CIHD) have been published with conflicting results. In this meta-analysis, we aimed to assess the effectiveness and safety of autologous bone marrow/blood-derived cell transplantation in patients with CIHD. METHODS Randomized controlled trials (RCTs) were identified in PubMed,(More)
We consider a network of sensors distributed in a target area providing environmental measurements that are subject to normally distributed, independent additive noise. Each sensor node applies a threshold rule to the measurements to decide the presence of a target; the distance to the target together with the threshold value determines its hit and false(More)
OBJECTIVES We sought to develop a new quantitative method to evaluate the degree of myocardial perfusion. BACKGROUND Currently available methods for assessing myocardial perfusion, both TIMI myocardial perfusion grading (TMPG) and myocardial blush grading (MBG), are subjective. METHODS TIMI Myocardial Perfusion Frame Count (TMPFC), an objective method(More)
OBJECTIVE The impact of gender on clinical course after ST-elevation myocardial infarction (STEMI) is not fully understood. We prospectively investigated whether there are gender-related differences in epicardial and myocardial tissue-level perfusion, both of which represent important prognostic determinants in STEMI patients undergoing primary percutaneous(More)
BACKGROUND AND AIMS Patients aged ≥75 years compose a high-risk subgroup for acute myocardial infarction (AMI). It is unknown whether myocardial perfusion in these patients is decreased compared with younger ones after primary percutaneous coronary intervention (PPCI), which may contribute to their worse prognosis. We compared epicardial and myocardial(More)
