Does EDPVR Represent Myocardial Tissue Stiffness? Toward a Better Definition [PDF]

arXiv
Accurate assessment of myocardial tissue stiffness is pivotal for the diagnosis and prognosis of heart diseases. Left ventricular diastolic stiffness ($\beta$) obtained from the end-diastolic pressure-volume relationship (EDPVR) has conventionally been utilized as a representative metric of myocardial stiffness.

Generative Ai for Cardiovascular Cell Type‐Specific Fluorescence Colorization of Live‐Cell hPSC‐Derived Cardiac Organoids

Advanced Intelligent Discovery, EarlyView.
A generative AI system is developed for colorizing phase contrast images of human pluripotent stem cell (hPSC)‐derived cardiac organoids (COs) from bright‐field microscopic imaging using conditional generative adversarial networks (cGANs). By giving these phase contrast images with multichannel fluorescence colorization, this intelligence system ...

In vivo toxic and lethal cardiorespiratory effects of a synthetic quaternary ammonium salt derivative of haloperidol in mice

Animal Models and Experimental Medicine, EarlyView.
Hematoxylin–eosin (H&E) stains of the heart, liver, lung, and kidney show acute toxicity. Abstract Background To investigate the toxicity of N‐n‐butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes. Methods The acute median lethal dose (LD50) of F2 was determined using the Bliss

Impact of prevention in primary care on costs in primary and secondary care for people with serious mental illness

Health Economics, Volume 32, Issue 2, Page 343-355, February 2023., 2023
Abstract A largely unexplored part of the financial incentive for physicians to participate in preventive care is the degree to which they are the residual claimant from any resulting cost savings. We examine the impact of two preventive activities for people with serious mental illness (care plans and annual reviews of physical health) by English ...

New Aspects for the Treatment of Cardiac Diseases Based on the Diversity of Functional Controls on Cardiac Muscles: Diversity in the Excitation–Contraction Mechanisms of the Heart

Journal of Pharmacological Sciences, 2009
The waveform of the myocardial action potential (AP) triggering contraction differs among the species, developmental stage, and pathological state. The species difference in heart rate, which inversely correlates with body size, originates in the ion ...
