OBJECTIVES This study assessed the time course of resolution of left atrial appendage (LAA) stunning after catheter ablation of chronic atrial flutter (AFL). BACKGROUND Although the presence of LAA stunning after ablation of chronic AFL calls for anticoagulation in the post-cardioversion period, limited information has been obtained, particularly regarding its duration. METHODS Sixteen pati...

We previously reported that preculture of fibroblasts (FBs) and endothelial cells (ECs) prior to cardiomyocytes (CMs) improved the structural and functional properties of engineered cardiac tissue compared to culture of CMs alone or co-culture of all three cell types. However, these approaches did not result in formation of capillary-like cords, which are precursors to vascularization in vivo. ...

Twenty trifluoromethylphenyl amides were synthesized and evaluated as fungicides and as mosquito toxicants and repellents. Against Aedes aegypti larvae, N-(2,6-dichloro-4-(trifluoromethyl)phenyl)-3,5-dinitrobenzamide (1e) was the most toxic compound (24 h LC50 1940 nM), while against adults N-(2,6-dichloro-4-(trifluoromethyl)phenyl)-2,2,2-trifluoroacetamide (1c) was most active (24 h LD50 19.18...

CM: Problem Management is a detailed problem management process model to be utilised within corrective maintenance. It has been developed at ABB and evaluated for its industrial relevance within 17 non-ABB organisations. In this paper, we present the evaluation results of CM: Problem Management. Our primary goal is to confirm its industrial relevance. Our secondary goal is to establish current ...

Introduction It is well-known that exposure to an enriched environment (EE) can induce plastic changes in the hippocampus and improves learning and memory in hippocampus-dependent tasks. The commonly used techniques in the previous studies on the effects of EE on brain include behavioral tests, electrophysiological recording, microdialysis and morphological evaluations of neurons and synapses. ...

We present the $NuSTAR$ extragalactic survey of $James$ $Webb$ $Space$ $Telescope$ ($JWST$) North Ecliptic Pole (NEP) Time-Domain Field. The covers a $\sim$0.16 deg$^2$ area with total exposure 681 ks acquired in nine observations from three epochs. sensitivities at 20% are 2.39, 1.14, 2.76, 1.52, and 5.20 $\times$ 10$^{-14}$ erg cm$^{-2}$ s$^{-1}$ 3-24, 3-8, 8-24, 8-16, 16-24 keV bands, respec...

BACKGROUND During both cardiac maturation and myopathy, elevated levels of circulating catecholamines coincide with alterations in impulse propagation. An in vitro model of cultured cardiomyocytes was used to study the effects of adrenergic stimulation on the conduction characteristics of immature heart cells. METHODS AND RESULTS Neonatal rat cardiomyocytes were cultured on preparations desig...

C M P0 4 The arrowed objects are tyrosine crystals. Tyrosine crystals are rare and their presence in urine is always abnormal. They form clusters of silky needle-like structures that are colorless, or black on focusing. Tyrosine crystals are found in acid urine, increase after refrigeration, and are insoluble in alcohol or ether. They are soluble in dilute hydrochloric acid, alkali and relative...
