Local extremality of the Calabi-Croke sphere for the length of the shortest closed geodesic [PDF]
Recently, F. Balacheff proved that the Calabi-Croke sphere made of two flat 1-unit-side equilateral triangles glued along their boundaries is a local extremum for the length of the shortest closed geodesic among the Riemannian spheres with conical ...

Mixed Valvular Disease Following Transcatheter Aortic Valve Replacement: Quantification and Systematic Differentiation Using Clinical Measurements and Image-Based Patient‐Specific In Silico Modeling [PDF]
Background: Mixed valvular disease (MVD), mitral regurgitation (MR) from pre‐existing disease in conjunction with paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR), is one of the most important stimuli for left ventricle (LV)

Inotropic interventions do not change the resting state of myosin motors during cardiac diastole
&NA; When striated (skeletal and cardiac) muscle is in its relaxed state, myosin motors are packed in helical tracks on the surface of the thick filament, folded toward the center of the sarcomere, and unable to bind actin or hydrolyze ATP (OFF state ...

In avian medicine, Doppler sonographic techniques are used to visualize and estimate blood flow in the heart. In the literature there is a lack of standardized studies of the use of color Doppler flow on healthy avian species.

Adiponectin Deficiency, Diastolic Dysfunction, and Diastolic Heart Failure [PDF]
Abstract Aldosterone infusion results in left ventricular hypertrophy (LVH) and hypertension and may involve profibrotic and proinflammatory mechanisms. In turn, hypertension is the major cause of diastolic heart failure (HF). Adiponectin, an adipose-derived plasma protein, exerts antiinflammatory and anti-hypertrophic effects and is ...

Diastolic Mitral Regurgitation
An 89-year-old female with a history of hypertension presented to the hospital with symptoms of fatigue. Her electrocardiogram (ECG) showed high-grade atrioventricular (AV) block, so a transthoracic echocardiogram was obtained to assess for structural heart abnormalities (Figure 1).

Background Accurate calculation of ventricular stress and strain is critical for cardiovascular investigations. Sarcomere shortening in active contraction leads to change of ventricular zero-stress configurations during the cardiac cycle.

Interactions between visceral afferent signaling and stimulus processing [PDF]
Visceral afferent signals to the brain influence thoughts, feelings and behaviour. Here we highlight the findings of a set of empirical investigations in humans concerning body-mind interaction that focus on how feedback from states of autonomic arousal ...
