Left ventricular systolic function in aortic stenosis [PDF]
, 2017 In aortic valve stenosis, concentric hypertrophy develops which is characterized by a reduced end-diastolic radius-to-wall thickness ratio (r/h) with an essentially normal cavity shape.

Electroactive Liquid Crystal Elastomers as Soft Actuators
Advanced Functional Materials, EarlyView.Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Estimation of elastic and viscous properties of the left ventricle based on annulus plane harmonic behavior [PDF]
, 2006 Assessment of left ventricular (LV) function with an emphasis on contractility has been a challenge in cardiac mechanics during the recent decades. The LV function is usually described by the LV pressurevolume (P-V) diagram. The standard P-V diagrams

An Ionic Gelation Powder for Ultrafast Hemostasis and Accelerated Wound Healing
Advanced Functional Materials, EarlyView.An ultrafast ionic gelation‐activated hemostatic powder (AGCL) forms a hydrogel within ≈1 s upon contact with blood‐derived calcium ions. The AGCL powder enables rapid hemorrhage control, strong tissue adhesion, and enhanced healing. The powder's pre‐crosslinked polymer network ensures high blood uptake and stability, offering effective treatment for ...

Association of tricuspid annular plane systolic excursion (TAPSE) with survival time in Boxer dogs with ventricular arrhythmias [PDF]
, 2015 BACKGROUND: Tricuspid annular plane systolic excursion (TAPSE) is a useful estimate of right ventricular function in humans. Reference intervals for dogs have been generated, but the value of measuring TAPSE in other diseases, or investigating the ...

A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds
Advanced Healthcare Materials, EarlyView.Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...

Left ventricular diastolic dysfunction: identifying presence by left atrial function
Echo Research and Practice, 2018 Objective: The left atrium (LA) is exposed to left ventricular pressure during diastole. Applying the 2016 American Society of Echocardiography left ventricular diastolic function (LVDF) guidelines, this study aims to investigate whether left atrial ...
