Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
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).

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).

Energy interconversion by the sarcoplasmic reticulum Ca2+-ATPase: ATP hydrolysis, Ca2+ transport, ATP synthesis and heat production

open access: yesAnais da Academia Brasileira de Ciências, 2000
The sarcoplasmic reticulum of skeletal muscle retains a membrane bound Ca2+-ATPase which is able to interconvert different forms of energy. A part of the chemical energy released during ATP hydrolysis is converted into heat and in the bibliography it is ...

Modeling effects of L-type ca(2+) current and na(+)-ca(2+) exchanger on ca(2+) trigger flux in rabbit myocytes with realistic T-tubule geometries. [PDF]

open access: yes, 2012
The transverse tubular system of rabbit ventricular myocytes consists of cell membrane invaginations (t-tubules) that are essential for efficient cardiac excitation-contraction coupling. In this study, we investigate how t-tubule micro-anatomy, L-type Ca(

The Mitochondrial Ca(2+) Uniporter: Structure, Function, and Pharmacology. [PDF]

open access: yes, 2017
Mitochondrial Ca(2+) uptake is crucial for an array of cellular functions while an imbalance can elicit cell death. In this chapter, we briefly reviewed the various modes of mitochondrial Ca(2+) uptake and our current understanding of mitochondrial Ca(2+)

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
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 ...

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]

open access: yes, 2009
Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

Pharmacological effects of gastrodin: Insight into neurological diseases and mechanism in ferroptosis and pyroptosis

open access: yesIbrain, Volume 11, Issue 1, Page 74-83, Spring 2025.
Pharmacological effects of gastrodin include prevention and treatment of cognitive decline and reperfusion injuries, anticonvulsion, antiepilepsy, antidepressants, and analgesia, which are related to antiferroptosis and antipyroptosis. Abstract Gastrodin, as an effective monomer of gastrodia elata, plays a significant role in anti‐inflammatory ...
