Electrophysiological effects of nicotinic and electrical stimulation of intrinsic cardiac ganglia in the absence of extrinsic autonomic nerves in the rabbit heart [PDF]
, 2018 BackgroundThe intrinsic cardiac nervous system is a rich network of cardiac nerves that converge to form distinct ganglia and extend across the heart and is capable of influencing cardiac function.ObjectiveThe goals of this study were to provide a ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Studies on deep learning dose prediction increasingly focus on 3D models with multiple input channels and data augmentation, which increases the training time and thus also the environmental burden and hampers the ease of re‐training. Here we compare 2D and 3D U‐Net models with clinical accepted plans to evaluate the appropriateness of

Hardware implementation for cardiac electrical excitation and conduction using an FPGA [PDF]
, 2017 Contraction of the heart is controlled by electrical excitations of cardiac cell membranes. The electrical excitations of the cells and their propagation in the heart tissue provide a basis of the physiological function of the heart through the cardiac ...

Cardiac Tissue Mapping Electrode Array to Determine Pro-Arrhythmic Tissue Substrates [PDF]
, 2016 Myocardial infarction (MI), commonly known as a heart attack, is the irreparable necrosis of the cardiac tissue due to sustained ischemia. MI may lead to heart failure.

ECG-Based Heart Arrhythmia Diagnosis Through Attentional Convolutional Neural Networks [PDF]
arXiv, 2021 Electrocardiography (ECG) signal is a highly applied measurement for individual heart condition, and much effort have been endeavored towards automatic heart arrhythmia diagnosis based on machine learning. However, traditional machine learning models require large investment of time and effort for raw data preprocessing and feature extraction, as well ...

Detection of low-conductivity objects using eddy current measurements with an optical magnetometer [PDF]
Phys. Rev. Research 1, 033087 (2019), 2019 Detection and imaging of an electrically conductive object at a distance can be achieved by inducing eddy currents in it and measuring the associated magnetic field. We have detected low-conductivity objects with an optical magnetometer based on room-temperature cesium atomic vapor and a noise-canceling differential technique which increased the signal-

Advanced Biology, EarlyView.In this article, the establishment and characterization of a self‐assembled 3D BBB spheroid model using human induced pluripotent stem cell (hiPSC)‐derived and primary cells is reported. Spheroids demonstrate in‐vivo like tight junction ultrastructure and, in comparison to 2D mono‐cultures, higher transcript expression of BBB specific genes.

Cardiac Development: A Glimpse on Its Translational Contributions
Hearts, 2021 Cardiac development is a complex developmental process that is initiated soon after gastrulation, as two sets of precardiac mesodermal precursors are symmetrically located and subsequently fused at the embryonic midline forming the cardiac straight tube.
