P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

open access: yesAdvanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Electromechanical modeling of human ventricles with ischemic cardiomyopathy: numerical simulations in sinus rhythm and under arrhythmia [PDF]

open access: yesarXiv, 2021
We developed a novel patient-specific computational model for the numerical simulation of ventricular electromechanics in patients with ischemic cardiomyopathy (ICM). This model reproduces the activity both in sinus rhythm (SR) and in ventricular tachycardia (VT).

Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management

open access: yesAdvanced Science, EarlyView.
Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

The ductal network in the human testis and epididymis: What belongs to which?

open access: yesClinical Anatomy, EarlyView.
Abstract The testes and epididymis are traversed by a system of tubules in which sperm cells are generated, matured, nourished, and transported. Among these are the efferent ductules, which connect the rete testis to the duct of the epididymis. In the Terminologia Anatomica (TA), the efferent ductules are assigned to the testicles, while numerous ...
