Development of neuromodulation for atrial fibrillation: a narrative review.

Background And Objective: Atrial fibrillation (AF) is a prevalent clinical arrhythmia with a high incidence of disability and mortality. Autonomic nervous system (ANS) plays a crucial role in the onset and persistence of AF, and can lead to electrophysiological changes and alterations in atrial structure. Both animal models and clinical findings suggest that parasympathetic and sympathetic activity within the cardiac ANS could induce atrial remodeling and AF.

Butyrate attenuates the stemness of lung cancer cells through lysosome Fe- and SLC7A11-mediated ferroptosis.

Cancer stem cells (CSCs) are considered key contributors to tumor progression, and ferroptosis has been identified as a potential target for CSCs. We have previously shown that butyrate enhances the ferroptosis induced by erastin in lung cancer cell, this study aimed to investigate the impact of butyrate on the progression of lung CSCs. To investigate these effects, we constructed a series of experiments, including 3D non-adherent sphere-formation, cytometry analysis, assessment of CSC marker expression, cell migration assay, and tumorigenesis analyses.

Butyrate enhances erastin-induced ferroptosis of lung cancer cells via modulating the ATF3/SLC7A11 pathway.

Ferroptosis is a novel form of programmed cell death triggered by iron-dependent lipid peroxidation and has been associated with various diseases, including cancer. Erastin, an inhibitor of system Xc-, which plays a critical role in regulating ferroptosis, has been identified as an inducer of ferroptosis in cancer cells. In this study, we investigated the impact of butyrate, a short-chain fatty acid produced by gut microbiota, on erastin-induced ferroptosis in lung cancer cells.

Solanum nigrum Polyphenol Extracts Inhibit Hepatic Inflammation, Oxidative Stress, and Lipogenesis in High-Fat-Diet-Treated Mice.

Patients with diabetes, obesity, and hyperlipidemia are all high-risk groups for fatty liver; however, the mechanism of fatty liver formation is not completely understood. Studies have indicated that abnormal fat metabolism, oxidative stress, and insulin resistance are positively correlated with peroxidation and abnormal cytokine production. Recent studies have revealed that Solanum nigrum extracts (SNE) possess anti-inflammatory, antioxidation, antihyperlipidemia, and liver protection abilities.
