Article Abstract
In different areas of the heart, action potential waveforms differ due to differences in the expressions of sodium, calcium, and potassium channels. One of the characteristics of myocardial infarction (MI) is an imbalance in oxygen supply and demand, leading to ion imbalance. After MI, the regulation and expression levels of K, Ca, and Na ion channels in cardiomyocytes are altered, which affects the regularity of cardiac rhythm and leads to myocardial injury. Myocardial fibroblasts are the main effector cells in the process of MI repair. The ion channels of myocardial fibroblasts play an important role in the process of MI. At the same time, a large number of ion channels are expressed in immune cells, which play an important role by regulating the in- and outflow of ions to complete intracellular signal transduction. Ion channels are widely distributed in a variety of cells and are attractive targets for drug development. This article reviews the changes in different ion channels after MI and the therapeutic drugs for these channels. We analyze the complex molecular mechanisms behind myocardial ion channel regulation and the challenges in ion channel drug therapy.

Anaerobic bacteria cause a wide range of infections, varying from mild to severe, whether localized, implant-associated, or invasive, often leading to high morbidity and mortality. These infections are challenging to manage due to antimicrobial resistance against common antibiotics such as carbapenems and nitroimidazoles. The empirical use of antibiotics has contributed to the emergence of resistant organisms, making the identification and development of new antibiotics increasingly difficult.

Neuroinflammation, a vital protective response for tissue homeostasis, becomes a detrimental force when chronic and dysregulated, driving neurological disorders like Alzheimer's, Parkinson's, and Huntington's diseases. Potassium (K) channels maintain membrane potential and cellular excitability in neurons and glia within the intricate CNS signaling network. Neuronal injury or inflammation can disrupt K channel activity, leading to hyperexcitability and chronic pain.

Background: The approval of cystic fibrosis transmembrane conductance regulator modulators elexacaftor/tezacaftor/ivacaftor (ETI), has significantly improved pulmonary function for people with cystic fibrosis (pwCF). However, the effects on CF-related bone disease and body composition remain unclear.
Methods: This retrospective real-world study examined adults with CF who received ETI treatment.

Background: Readily available treatments for Alzheimer's disease and related dementia (ADRD) include acetylcholinesterase inhibitors and N-methyl-D-aspartate receptor antagonists. Non-adherence and early discontinuation of anti-dementia medications are prevalent issues. We aimed to investigate factors associated with suboptimal usage of anti-dementia medications in ADRD.

As a new generation of high-energy-density energy storage system, solid-state aluminum-ion batteries have attracted much attention. Nowadays polyethylene oxide (PEO)-based electrolytes have been initially applied to Lithium-ion batteries due to their flexible processing and good interfacial compatibility, their application in aluminum-ion batteries still faces problems. To overcome the limitations in aluminum-ion batteries-specifically, strong Al coordination suppressing ion dissociation, high room-temperature crystallinity, and inadequate mechanical strength-this study develops a blended polymer electrolyte (BPE) of polypropylene carbonate (PPC) and PEO.
