Sodium Alginate Attenuates HO-Induced Myocardial DNA Damage via VSNL1 Regulating the CNP/NPR-B Signaling Pathway.

Myocardial DNA damage plays a critical role in the pathogenesis of cardiovascular diseases, frequently leading to adverse outcomes such as myocardial infarction and heart failure. This study elucidated the protective effects of sodium alginate (SA) against myocardial DNA damage and explored the underlying molecular mechanisms involved. Hydrogen peroxide (H₂O₂) -stimulated AC16 cells were employed as an in vitro model to induce myocardial DNA damage, and CCK-8 assays established that SA exhibited no cytotoxicity at concentrations up to 800 µM.

Ce-MOF@Au-Based Electrochemical Immunosensor for Apolipoprotein A1 Detection Using Nanobody Technology.

Apolipoprotein A1 (Apo-A1) is a well-recognized biomarker in tissues, closely associated with cardiovascular diseases such as atherosclerosis, coronary artery disease, and heart failure. However, existing methods for Apo-A1 determination are limited by costly equipment and intricate operational procedures. Given the distinct advantages of electrochemical immunosensors, including affordability and high sensitivity, along with the unique attributes of nanobodies (Nbs), such as enhanced specificity and better tissue permeability, we developed an electrochemical immunosensor for Apo-A1 detection utilizing Nb technology.
