Tanshinone I promotes angiogenesis and improves ventricular remodeling post-myocardial infarction via ALDH2 signaling-mediated ferroptosis inhibition.

Background: Tanshinone I (Tan I) has diverse cardioprotective effects, including improving post-myocardial infarction (MI) ventricular remodeling. Ventricular remodeling can be improved by inhibiting endothelial cell (EC) ferroptosis to promote post-MI angiogenesis, but how Tan I does this remains unclear. Thus, we investigated how EC ferroptosis mediates post-MI angiogenesis and Tan I's role in this process.

Macrophage-Capturing Self-Assembly Photosensitizer Nanoparticles Induces Immune Microenvironment Re-Programming and Golgi-Responsive Immunogenic Cell Death in Head and Neck Carcinoma.

Head and neck carcinoma treatment is shifted toward the combination of therapy causing immune checkpoint blockade (ICB) and immunogenic cell death. In this study, a CSFRi-chimeric TAM-targeting extracellular vesicle (EV@CSFRi) platform is developed and designed an intracellular protoporphyrin conjugated with RVRR peptide sequence for furin-cleavage to perform Golgi-targeting and generating ROS (GT-RG). The graphical abstract illustrates the self-assembly of GT-RG nanoparticles into nanofiber through the hydrophily of RVRR and hydrophobicity of RG, and the red line indicates the site of furin cleavage.

This study was aimed to explore whether pirfenidone could protect against RIF, and to evaluate the underlying mechanism.

Garlic intake lowers fasting blood glucose: meta-analysis of randomized controlled trials.

Garlic is a common spicy flavouring agent also used for certain therapeutic purposes. Garlic's effects on blood glucose have been the subject of many clinical and animal studies, however, studies reporting hypoglycemic effects of garlic in humans are conflicting. A comprehensive literature search was conducted to identify relevant trials of garlic or garlic extracts on markers of glycemic control [fasting blood glucose (FBG), postprandial glucose (PPG), glycosylated haemoglobin (HbA1c)].

Astragaloside IV regulates expression of ATP-sensitive potassium channel subunits after ischemia-reperfusion in rat ventricular cardiomyocytes.

Objective: Astragaloside IV (AsIV) is the major effective component extracted from the Chinese herb Astragalus membranaceus, which has been widely used to treat cardiovascular disease. Recent studies have shown that AsIV can potentially protect the heart from myocardial ischemic injury, but the mechanisms of action are unknown. ATP-sensitive potassium (KATP) channels are activated during ischemia and exert a compensatory protective effect on cardiomyocytes.
