OBJECTIVES We investigated the myocardial localization and expression of tissue factor (TF) and alternatively spliced human tissue factor (asHTF) in patients with dilated cardiomyopathy (DCM). BACKGROUND Tissue factor is expressed in cardiac muscle and may play a role in maintaining myocardial structure. METHODS Myocardial biopsies were obtained from patients with a normal or mildly impaire...
Background: We aimed to analyze the prevalence and long-term prognostic impact of non-cardiac comorbidities in patients with reduced preserved left-ventricular ejection fraction (EF) following ST-elevation myocardial infarction (STEMI). Method: A total 3033 STEMI undergoing primary percutaneous coronary intervention (pPCI) were divided two groups: EF < 50% ≥ 50%. The follow-up period was 8 y...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
Background—Tumor necrosis factor(TNF ), an inflammatory cytokine, was reported to be elevated in trials of heart failure (HF) with reduced ejection fraction (EF) and associated with mortality. Whether this is true for HF with preserved EF is unknown, and community data are lacking. We evaluated the distribution of TNF , its association with baseline characteristics and mortality, and its benefi...
background : airborne particulate matter is one of the most important atmospheric pollutants. tile sources of particulate matter in the atmosphere are divided into two groups; 1) natural sources and 2) anthropogenic sources. the important components of airborne particulate matter and invarying concentrations are the ubiquitous components of the lower atmosphere. heavy metals are mainly emitted ...
Exercise-induced fatigue (EF) is a ubiquitous phenomenon in sports competition and training. It can impair athletes' motor skill execution and cognition. Corticostriatal synaptic plasticity is considered to be the cellular mechanism of movement control and motor learning. However, the effect of EF on corticostriatal synaptic plasticity remains elusive. In the present study, using field excitato...
Low-amplitude electric field (EF) is an important component of wound-healing response and can promote vascular tissue repair; however, the mechanisms of action on endothelium remain unclear. We hypothesized that physiological amplitude EF regulates angiogenic response of microvascular endothelial cells via activation of the mitogen-activated protein kinase/extracellular signal-regulated kinase ...
This article offers an account of embodied exchange with the world that associates conscious operations with actively inferring the causes of our sensations. Its agenda is to link formal (mathematical) descriptions of dynamical systems to a description of perception in terms of beliefs and goals. The argument has two parts: the first calls on the lawful dynamics of any (weakly mixing ergodic) s...
