Using high temporal resolution ( HTR) MRI method to analyze the left ventricular function of a diabetic rat model [abstract] [PDF]
, 2010 High-temporal-resolution (HTR) cardiac cine- magnetic resonance imaging (MRI) is a novel technique which provides much more image frames during one cardiac cycle than conventional cardiac cine-MRI method. Subtle alterations and features of diseased heart

Advanced Functional Materials, EarlyView.CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

On the Einthoven Triangle: A Critical Analysis of the Single Rotating Dipole Hypothesis
Sensors, 2018 Since its inception, electrocardiography has been based on the simplifying hypothesis that cardinal limb leads form an equilateral triangle of which, at the center/centroid, the electrical equivalent of the cardiac activity rotates during the cardiac ...

Sarcomere Control Mechanisms and the Dynamics of the Cardiac Cycle [PDF]
Journal of Biomedicine and Biotechnology, 2010 This review focuses on recent developments in the molecular mechanisms by which Ca activates cardiac sarcomeres and how these mechanisms play out in the cardiac cycle. I emphasize the role of mechanisms intrinsic to the sarcomeres as significant determinants of systolic elastance and ventricular stiffening during ejection. Data are presented supporting

Advanced Healthcare Materials, EarlyView.Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

Multiple mechanisms of spiral wave breakup in a model of cardiac electrical activity
, 2002 It has become widely accepted that the most dangerous cardiac arrhythmias are due to re- entrant waves, i.e., electrical wave(s) that re-circulate repeatedly throughout the tissue at a higher frequency than the waves produced by the heart's natural ...
