Single-Cell and Machine Learning Analyses Identify a PFKFB3-Centered Regulatory Network and Potential Salidroside Interaction in Coronary Heart Disease.
Coronary heart disease (CHD) is a leading cause of morbidity and mortality, driven by metabolic remodeling, vascular inflammation, and perivascular adipose tissue (PVAT) dysfunction. We integrated bul...
Beyond Bone Health: Exploring the "Heart-Brain-Bone" Axis Modulated by Lipid-Soluble Nutrients (Omega-3, Vitamin D3, and Vitamin K2).
BACKGROUND: Population aging is driving a convergent rise in three disorders historically managed in isolation: cardiovascular disease, neurocognitive decline, and osteoporotic bone loss. Mechanistic ...
BDNF/TrkB Signaling in Intracardiac Ganglia Modulates Cardiac Parasympathetic Tone.
Brain-derived neurotrophic factor (BDNF) impacts parasympathetic nervous system function by increasing the excitability of cardioinhibitory parasympathetic neurons in the brainstem, ultimately lowerin...
Reduced microvascular coverage links a hypoxia-associated niche to microglial autophagic dysfunction in Parkinson's disease.
Microglial hyperactivation contributes to Parkinson's disease (PD) progression, yet the upstream microenvironmental cues that sustain this state remain incompletely understood. While α-synuclein (α-Sy...
Pirfenidone restores metabolic hormones and cardiac autophagy via p-AMPK in MASH.
BACKGROUND: Obesity promotes chronic inflammation and insulin resistance, disrupting key metabolic hormones (e.g., insulin and leptin) and triggering metabolic dysfunction-associated steatohepatitis (...
Microvascular remodeling and endothelial dysfunction across the post-COVID-19 spectrum: a prospective observational case-control study.
BACKGROUND: Post-viral diseases, including post-COVID-19 syndrome (PCS) and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), cause substantial long-term morbidity. Persistent cardiovascula...
Intraluminal morphometric analysis of abdominal aortic branches: spatial landmarks for interventional radiology and colorectal surgery.
PURPOSE: Precise knowledge of the spatial relationships of abdominal aortic branches is essential for safe colorectal surgery and interventional radiologic (IR) procedures. While most studies describe...
Natriuretic peptide responses to exercise in HFpEF diagnosis: a pilot study.
BACKGROUND: Diagnosing heart failure with preserved ejection fraction (HFpEF) can be challenging because natriuretic peptide (NP) plasma levels and diastolic function parameters during rest echocardio...
Four-year evolution of the retinal microvasculature in an APOE ε4/ε4 cognitively normal individual.
Alzheimer's disease is a neurodegenerative disorder with a prolonged preclinical phase during which pathological changes begin 15-20 years before clinical presentation. We present longitudinal optical...
Endovenous Treatment Of Superficial Chronic Venous Disease In A Strict Ambulatory Setting: A Single-Center Experience.
INTRODUCTION: Minimally invasive endovenous techniques have become central to the treatment of superficial chronic venous disease (CVD) of the lower limbs. Their ability to avoid general or locoregion...
Plozasiran: a small interfering RNA therapy for hypertriglyceridemia and familial chylomicronemia syndrome.
Plozasiran (Redemplo®) is a small interfering RNA that reduces hepatic production of apolipoprotein C-III and circulating triglycerides. It degrades ApoC-III mRNA and results in reduced levels of hepa...
Multicenter External Validation of an AI-Based Funduscopic Carotid Atherosclerosis Score and Assessment of Its Association With Coronary Artery Calcification: External Validation Study.
BACKGROUND: Screening for atherosclerosis is essential for early intervention, but conventional screening methods are often invasive and resource-intensive. As a result, there is growing interest in l...
Exercise After Coronary Stenting: Potential Effects on in-Stent Restenosis.
PURPOSE OF REVIEW: Structured exercise is a cornerstone of secondary prevention after percutaneous coronary intervention (PCI), yet its specific relationship with in-stent restenosis (ISR) is less wel...
Combined use of SGLT2 inhibitor and GLP-1 receptor agonist versus either monotherapy for cardiorenal Outcomes: an exploratory network meta-analysis of 16 randomized trials.
BACKGROUND: Sodium-glucose co-transporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) each provide cardiorenal protection in trials of selected populations, but their...
Efficacy of multi-layered human iPS cell-derived cardiovascular cell sheets in a pacing-induced canine dilated cardiomyopathy model.
BACKGROUND: Dilated cardiomyopathy (DCM) is a progressive, intractable disease that leads to heart failure. Heart transplantation is the only curative treatment; however, access is limited by donor sc...
