Large conductance voltage- and calcium-activated potassium channels (BK channels) are extensively found throughout the central nervous system and play a crucial role in various neuronal functions. These channels are activated by a combination of cell membrane depolarisation and an increase in intracellular calcium concentration, provided by calcium sources located close to BK. In 2001, Isaacson and Murphy first demonstrated the coupling of BK channels with N-methyl-D-aspartate receptors (NMDAR) in olfactory bulb neurons.

Hyperoxaluria, including primary and secondary hyperoxaluria, is a disorder characterized by increased urinary oxalate excretion and could lead to recurrent calcium oxalate kidney stones, nephrocalcinosis and eventually end stage renal disease. For secondary hyperoxaluria, high dietary oxalate (HDOx) or its precursors intake is a key reason. Recently, accumulated studies highlight the important role of gut microbiota in the regulation of oxalate homeostasis.

Salivary gland diseases encompass a broad range of conditions, including autoimmune, inflammatory, obstructive, and neoplastic disorders, significantly impacting oral health and overall well-being. Recent research has highlighted the crucial role of exosomes, small extracellular vesicles, in these diseases. Exosomes mediate intercellular communication by transferring bioactive molecules such as proteins, microRNAs, and lipids, positioning them as potential diagnostic biomarkers and therapeutic agents.

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.

Hyperkalemia, characterized by elevated serum potassium levels, poses significant health risks, including life-threatening cardiac arrhythmias. The management of hyperkalemia has evolved, incorporating calcium polystyrene sulfonate (CPS) and newer agents such as sodium zirconium cyclosilicate (SZC) and patiromer alongside traditional treatments. This review provides a comprehensive examination of current management strategies for hyperkalemia, focusing on the comparative effectiveness, safety profiles, and patient preferences concerning CPS, SZC, and patiromer.
