Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

Functional role of t-tubules on calcium transients in canine cardiac myocytes
Background: A loss of t-tubules and alterations in ultrastructure occur in cultured ventricular myocytes. A similar alteration in t-tubules and ultrastructure is well documented under certain pathological conditions such as heart failure. We examined the

Imaging Calcium Sparks in Cardiac Myocytes [PDF]
Calcium ions play fundamental roles in many cellular processes in virtually all type of cells. The use of Ca(2+) sensitive fluorescent indicators has proven to be an indispensable tool for studying the spatio-temporal dynamics of intracellular calcium ([Ca(2+)](i)).

Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Abstract Aims Iron deficiency (ID) is prevalent in chronic heart failure (HF) but lacks a consensus definition. This study evaluates the prevalence and the prognostic impact of ID using different criteria on all‐cause and cardiovascular mortality, as well as first hospitalization for HF in patients with new‐onset chronic HF.

Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Abstract Background Cardiac remodelling, a crucial aspect of heart failure, is commonly investigated in preclinical models by quantifying cardiomyocyte cross‐sectional area (CSA) and microvascular density (MVD) via histological methods, such as immunohistochemistry.

Integrating ER and Mitochondrial Proteostasis in the Healthy and Diseased Heart
The integrity of the proteome in cardiac myocytes is critical for robust heart function. Proteome integrity in all cells is managed by protein homeostasis or proteostasis, which encompasses processes that maintain the balance of protein synthesis ...

Artificial intelligence in preclinical epilepsy research: Current state, potential, and challenges
Abstract Preclinical translational epilepsy research uses animal models to better understand the mechanisms underlying epilepsy and its comorbidities, as well as to analyze and develop potential treatments that may mitigate this neurological disorder and its associated conditions. Artificial intelligence (AI) has emerged as a transformative tool across
