Induction of endogenous regenerative capacity has emerged as one promising approach to repair damaged hearts following myocardial infarction (MI). Re-expression of factors that are exclusively expressed during embryonic development may reactivate the ability of adult cardiomyocytes to regenerate. Here, we identified miR-411 as a potent inducer of cardiomyocyte proliferation. Overexpression of miR-411 in the heart significantly increased cardiomyocyte proliferation and survival in a model MI. We found that miR-411 enhances the activity of YAP, the main downstream effector of the Hippo pathway, in cardiomyocytes. In conclusion, miR-411 induces cardiomyocyte regeneration and improves cardiac function post-MI likely by modulating the Hippo/YAP pathway.

Purpose: To compare the overall survival and the risk of all-cause and heart failure-specific hospitalization in nonagenarian patients hospitalized for symptomatic severe aortic stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI) or conservative treatment.
Methods: Population-based retrospective cohort study based on healthcare utilization databases of the Italian region of Lombardy. The cohort included all nonagenarians hospitalized for AS between 2017 and 2021, who underwent TAVI within 90 days from first diagnosis or conservative treatment.

Hepatic stores of Vitamin A (retinol) are mobilized and metabolized in the heart following myocardial infarction. The physiological consequences of this mobilization are poorly understood. Here we used dietary depletion in a lecithin retinol acyltransferase mutant mouse line to induce Vitamin A deficiency and investigate the effects on cardiac function and recovery from myocardial infarction.

Introduction: When exercising to preferred music (PM), participants found more satisfaction and less typical exercise-related fatigue, which made it easier and more enjoyable to maintain the physical activity (PA) until the exercise goals were achieved. The purpose of this review and meta-analysis was to determine whether changes on internal training load in adult recreational athletes were modified by listening to PM and non-preferred music (NPM), during different PA.
Evidence Acquisition: A music-focused search was performed on the Google Scholar, PubMed, and Web of Science databases to identify relevant articles to this topic published after 2000 to investigate the effects of PM on psychophysiological responses to PA.

Objectives: Tangier disease (TD) is a rare autosomal recessive condition characterized by high-density lipoprotein (HDL) deficiency; involving symptoms of polyneuropathy, hyperplastic orange-yellow tonsils, vision disorder, and sudden cardiac death. The major clinical symptoms of TD may not all be co-present. This study evaluates patients diagnosed with TD in childhood to improve the possibility of early diagnosis of asymptomatic cases by reporting our patients' clinical characteristics in order to minimize delayed diagnosis and emphasize the importance of TD, easily detected by HDL measurement.
