Hydrogen sulfide (HS) has been highlighted as an important gasotransmitter in mammals. A growing number of studies have indicated that HS plays a key role in the pathophysiology of vascular diseases and physiological vascular homeostasis. Alteration in HS biogenesis has been reported in a variety of vascular diseases and HS supplementation exerts effects of vasodilation. Accumulating evidence has shown vascular potassium channels activation is involved in HS-induced vasodilation. This review aimed to summarize and discuss the role of HS in the regulation of vascular tone, especially by interaction with different vascular potassium channels and the underlying mechanisms.

Aldosterone is a key regulator of fluid and electrolyte balance in the body. It is often dysregulated in heart failure (HF) and is a key driver of cardiac remodelling and worse clinical outcomes. Potassium regulation is essential for normal cardiac, gastrointestinal and neuromuscular function.

Despite significant advances in its management, AF remains a major healthcare burden affecting millions of individuals. Rhythm control with antiarrhythmic drugs or catheter ablation has been shown to improve symptoms and outcomes in AF patients, but current treatment options have limited efficacy and/or significant side-effects. Novel mechanism-based approaches could potentially be more effective, enabling improved therapeutic strategies for managing AF.

Purpose: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is beneficial for uncontrollable torso bleeding; however, prolonged REBOA causes ischemia-reperfusion injury. The purpose of this study is to examine the hypothesis that continuous renal replacement therapy (CRRT) with a cytokine-adsorbing hemofilter would improve mortality due to hemorrhagic shock with REBOA-reperfusion injury by controlling metabolic acidosis, hyperkalemia, and hypercytokinemia.
Methods: Hemorrhagic shock with 40% blood loss was induced by phlebotomy in eight female swine.

Objectives: We aimed to: (1) explore the effect of oral potassium supplementation on urinary potassium excretion, and (2) evaluate the value of urinary potassium-related indicators in distinguishing primary aldosteronism (PA) from non-PA patients.
Design And Methods: A prospective study of 20 patients with hypertension and hypokalemia caused by renal potassium loss between November 2023 and April 2024 was conducted. Demographic features, 24-hour urine collection before and after potassium supplementation were all collected.

Calcium phosphate (CaP)-based bioscaffolds are used for bone tissue regeneration because of their physical and chemical resemblance to human bone. Calcium, phosphate, sodium, potassium, magnesium, and silicon are important components of human bone. The successful biomimicking of human bone characteristics involves incorporating all the human bone elements into the scaffold material.
