BACKGROUND Elevated heart rate is associated with increased cardiovascular morbidity. The selective I(f) current inhibitor ivabradine reduces heart rate without affecting cardiac contractility, and has been shown to be cardioprotective in the failing heart. Ivabradine also exerts some of its beneficial effects by decreasing cardiac proinflammatory cytokines(More)
BACKGROUND In recent years, catheter ablation has increasingly been used for ablation of idiopathic premature ventricular complexes (PVCs) or ventricular tachycardias (IVTs). However, the mapping and catheter ablation of the arrhythmias originating from the vicinity of tricuspid annulus (TA) may not be fully understood. This study aimed to investigate(More)
Innate lymphocytes play a key role in maintaining the immune bowel barrier, which provides resistance to infection. However, the effects of probiotics on changes in the function of innate lymphocytes in the postoperative intestine remain known. Ninety-six male SD rats were divided into the blank group and the preoperative Lactobacillus intervention group,(More)
In sensor networks, sensor measurements may be uncertain due to the impact of environment and different performances of sensors. In this paper, the cross-covariance matrix of prediction errors between any two sensor subsystems is derived for stochastic discrete-time linear systems with uncertain observations by using projection theory. Based on the linear(More)
Six non-lactating Chinese goats (average weight 40±2 kg) fed low forage (LF) or high forage (HF) diets were used in a randomized crossover trial to determine the net flux of VFA across portal-drained viscera and liver for 8 h from initial feeding. Chronic catheters were established in mesenteric, portal, and hepatic veins, and femoral artery to measure the(More)
Based on PLC, this paper blends the automatic control theory with the feed processing industry and carries out design and research on the feed production automatic control system. Mainly employing the method of combining the upper computer with the PLC, this system can collect, recognize and control data to progressively implement the automatic control of(More)
BACKGROUND The role of β-adrenergic stimulation on viral myocarditis has been investigated in animal models of viral myocarditis. Excess stimulation of β-adrenergic receptors by catecholamines causes phosphorylation/activation of cAMP response element binding protein (CREB) by the cAMP signaling pathway. CREB as an important regulator of gene expression(More)
