Spontaneous initiation of atrial fibrillation by ectopic beats originating in the pulmonary veins.
New England Journal of Medicine, 1998 BACKGROUND Atrial fibrillation, the most common sustained cardiac arrhythmia and a major cause of stroke, results from simultaneous reentrant wavelets. Its spontaneous initiation has not been studied.

Uniform spatial distribution of collagen fibril radii within tendon implies local activation of pC-collagen at individual fibrils [PDF]
Physical Biology, v. 13 (2016) 046008, 2016 Collagen fibril cross-sectional radii show no systematic variation between the interior and the periphery of fibril bundles, indicating an effectively constant rate of collagen incorporation into fibrils throughout the bundle. Such spatially homogeneous incorporation constrains the extracellular diffusion of collagen precursors from sources at the ...

A resorcinarene for inhibition of Aβ fibrillation. [PDF]
, 2017 Amyloid-β peptides (Aβ) fibrillation is the hallmark of Alzheimer's disease (AD). However, it has been challenging to discover potent agents in order to inhibit Aβ fibrillation.

Edoxaban versus warfarin in patients with atrial fibrillation.
New England Journal of Medicine, 2013 BACKGROUND Edoxaban is a direct oral factor Xa inhibitor with proven antithrombotic effects. The long-term efficacy and safety of edoxaban as compared with warfarin in patients with atrial fibrillation is not known.

Rivaroxaban versus warfarin in nonvalvular atrial fibrillation.
New England Journal of Medicine, 2011 BACKGROUND The use of warfarin reduces the rate of ischemic stroke in patients with atrial fibrillation but requires frequent monitoring and dose adjustment.

Temperature diagnostics of chromospheric fibrils [PDF]
A&A 672, A89 (2023), 2023 Context. Chromospheric fibrils are thin and elongated structures that connect nearby photospheric magnetic field concentrations of opposite polarities. Aims. We assess the possibilities and drawbacks related to the use of current instrumentation and inversion techniques to infer the thermodynamic structure of chromospheric fibrils. Methods. We employed

RHYTHM-AF: design of an international registry on cardioversion of atrial fibrillation and characteristics of participating centers [PDF]
, 2012 BACKGROUND Atrial fibrillation is a serious public health problem posing a considerable burden to not only patients, but the healthcare environment due to high rates of morbidity, mortality, and medical resource utilization. There are limited data on the

Amyloid Fibril Solubility [PDF]
J. Phys. Chem. B, 2015, 119 (46), pp 14631-14636, 2015 It is well established that amyloid fibril solubility is protein specific, but how solubility depends on the interactions between the fibril building blocks is not clear. Here we use a simple protein model and perform Monte Carlo simulations to directly measure the solubility of amyloid fibrils as a function of the interaction between the fibril ...
