Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

Intermittent Fasting Restores Cardiac Lipid Homeostasis in Diabetic Cardiomyopathy in Association With Akkermansia Muciniphila and 1‐methyl‐L‐histidine

open access: yesAdvanced Science, EarlyView.
Intermittent fasting reshapes the gut microbiota in diabetic cardiomyopathy, restoring Akkermansia muciniphila and the microbiota‐associated metabolite 1‐methyl‐L‐histidine. This shift is linked to improved cardiac lipid homeostasis, reduced lipid peroxidation, and attenuated myocardial injury, highlighting a gut microbiota–metabolite–lipid axis in ...

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

open access: yesAdvanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Three dimensional echocardiography in congenital heart defects

open access: yesAnnals of Pediatric Cardiology, 2008
Three dimensional echocardiography (3DE) is a new, rapidly evolving modality for cardiac imaging. Important technological advances have heralded an era where practical 3DE scanning is becoming a mainstream modality. We review the modes of 3DE that can be

Refining a preclinical model of viral myocarditis in accordance with biotech standards

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study aimed to refine a murine model of Coxsackievirus B3‐induced myocarditis by integrating dietary and imaging innovations to improve animal welfare, data quality, and clinical applicability. The refined diet significantly reduced animal health burden, reduced weight loss, and stabilized blood glucose during development of cardiac inflammation ...

Analysis of energy expenditure and behavioral characteristics in different mouse strains under normal and disease conditions

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Mouse metabolic and behavioral phenotypes are tightly linked to strain, age and disease state, with distinct dysregulation in each disease model, underscoring the need for standardized preclinical experimental conditions. Abstract Background Metabolic and behavioral traits in mice exhibit substantial variability across strains, ages, and disease states,

Mitral valvuloplasty using real‐time three‐dimensional transesophageal echocardiography

open access: yesAnnals of Noninvasive Electrocardiology
Objective This study aimed to investigate the structure of the mitral valve in patients undergoing mitral valvuloplasty (MVP) using real‐time three‐dimensional transesophageal echocardiography (RT‐3D‐TEE). The main objective was to study the relationship
