Heart Failure in Humans Reduces Contractile Force in Myocardium from Both Ventricles [PDF]
, 2020 This study measured how heart failure affects the contractile properties of the human myocardium from the left and right ventricles. The data showed that maximum force and maximum power were reduced by approximately 30% in multicellular preparations from

Adversarial Convolutional Networks with Weak Domain-Transfer for Multi-sequence Cardiac MR Images Segmentation [PDF]
, 2019 Analysis and modeling of the ventricles and myocardium are important in the diagnostic and treatment of heart diseases. Manual delineation of those tissues in cardiac MR (CMR) scans is laborious and time-consuming.

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects
Advanced Functional Materials, EarlyView.Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

A piece of hammer in the right ventricle of the heart
Case Reports, 2009 A 29-year-old male was referred to the surgery department with face injury after being hit with a small hammer fragment at work. Upon admission, he was slightly bleeding from the lacerated wound (size of 1×1 cm) in the maxillofacial region. Radiograph of the skull detected a small dense fragment in the region of injury (fig 1) and the patient was ...

Echocardiographic recognition of a criss-cross heart with double outlet right ventricle [PDF]
, 2013 Crisscross heart (CCH) is a rare cardiac malformation characterized by crossing of the inflow streams of the two ventricles due to an apparent twisting of the heart about its long axis.

Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Importance of the right ventricle in valvular heart disease [PDF]
European Heart Journal, 1996 The importance of the right ventricle as a determinant of clinical symptoms, exercise capacity, peri-operative survival and postoperative outcome has been underestimated for a long time. Right ventricular ejection fraction has been used as a measure of right ventricular function but has been found to be dependent on loading conditions, ventricular ...

Advanced Healthcare Materials, EarlyView.Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.

Development of the heart: (2) Septation of the atriums and ventricles [PDF]
Heart, 2003 In the first part of our review of cardiac development,1 we discussed the initial changes involved in transformation of the heart forming regions of the embryo into the great veins, the atrial and ventricular chambers, and the arterial trunks. We showed that this first part of cardiac development could be divided into phases of formation of the primary

Functional modulation of the transient outward current Ito by KCNE beta-subunits and regional distribution in human non-failing and failing hearts [PDF]
, 2006 Objectives: The function of Kv4.3 (KCND3) channels, which underlie the transient outward current I,, in human heart, can be modulated by several accessory subunits such as KChIP2 and KCNE1-KCNE5.
