What drives amyloid molecules to assemble into oligomers and fibrils? [PDF]

, 2010
We develop a general theory for three states of equilibrium of amyloid peptides: the monomer, oligomer, and fibril. We assume that the oligomeric state is a disordered micelle-like collection of a few peptide chains held together loosely by hydrophobic interactions into a spherical hydrophobic core.

Preclinical Testing of a Novel Extracorporeal Membrane Oxygenation System in an Acute Cardiogenic Shock Animal Model

Organ Medicine, Volume 2, Issue 1, Page 50-59, March 2025.
Preclinical studies with appropriate large animal experimental models are critical to the development of extracorporeal membrane oxygenation (ECMO) technology. This study highlights the safety and efficacy of the novel HuiSheng‐1 ECMO system, which provides reliable life support in a large animal model of ACS.

Modeling generic aspects of ideal fibril formation [PDF]

J. Chem. Phys. 144, 035101 (2016), 2016
Many different proteins self-aggregate into insoluble fibrils growing apically by reversible addition of elementary building blocks. But beyond this common principle, the modalities of fibril formation are very disparate, with various intermediate forms which can be reshuffled by minor modifications of physico-chemical conditions or amino-acid ...

A Novel Technique of Left Atrial Decompression Using Intracardiac Echocardiography Guidance in 2 Dogs With Advanced Degenerative Mitral Valve Disease

Journal of Veterinary Internal Medicine, Volume 39, Issue 2, March/April 2025.
ABSTRACT Left atrial decompression (LAD) using transseptal puncture followed by balloon atrial septostomy recently has been described as a palliative minimally invasive procedure in dogs with advanced degenerative mitral valve disease (DMVD). We report herein the first use of intracardiac echocardiography (ICE) guidance combined with 3‐dimensional ...

Encerramento percutâneo do apêndice auricular esquerdo para profilaxia de tromboembolismo na fibrilhação auricular

Revista Portuguesa de Cardiologia, 2013
Resumo: A fibrilhação auricular é uma arritmia frequente na prática clínica. Associa-se a morbilidade e a mortalidade elevadas, em virtude do seu potencial tromboembólico, o que confere especial relevância à profilaxia do tromboembolismo.

Adipochondrocytes in rabbit auricular cartilage [PDF]

arXiv, 2018
Chondrocytes are described as one cell population in different cartilage types. The auricular cartilage in mouse and rat contains unique chondrocytes similar in morphology to white adipocytes and known as lipochondrocytes. Lipochondrocytes were not mentioned in other species. The current study aimed to explore the existence of this cell type in rabbits.

Bayliss Starling Prize Lecture 2023: Neuropeptide‐Y being ‘unsympathetic’ to the broken hearted

The Journal of Physiology, Volume 603, Issue 7, Page 1841-1864, 31 March 2025.
Abstract figure legend The hallmark of cardiac disease is autonomic dysregulation, characterised by a state of chronic sympathoexcitation. Neuropeptide‐Y (NPY) is a sympathetic co‐transmitter that is released by sympathetic neurons and circulating venous levels are elevated in a range of cardiac disease, such as myocardial infarction and chronic heart ...
