Animal models for investigating post‐stroke cognitive impairment: A neurovascular trafficking perspective

Animal Models and Experimental Medicine, EarlyView.
Animal models enable mechanistic testing of how ischemic injury disrupts neurovascular trafficking and drives cognitive vulnerability after stroke. Complementary models capture distinct vascular, cellular, white matter, and cognitive features of PSCI.

Atrial natriuretic factor (ANF) and renin-aldosterone in volume regulation of patients with cirrhosis [PDF]

, 1989
The role of the atrial natriuretic factor and of the main counteracting sodium-retaining principle, the renin-aldosterone system, in acute volume regulation of cirrhosis of the liver has been investigated.

Centrum Semiovale Perivascular Spaces Predict First Hemorrhagic Lesion in Asymptomatic Amyloid‐Positive Individuals

Annals of Neurology, EarlyView.
Objective Identification of cerebral amyloid angiopathy (CAA) before its hemorrhagic manifestations remains limited. We aimed to determine whether severe enlarged perivascular spaces in the centrum semiovale (EPVS‐CSO) identify a prehemorrhagic stage of sporadic CAA by predicting the first appearance of CAA‐related hemorrhagic lesions or incident ...

Morphological variation of the conus arteriosus in Chondrichthyes: Implications for ecology and evolution

The Anatomical Record, EarlyView.
Abstract Cartilaginous fish have diverse morphological traits that are essential for understanding their evolutionary history and ecological adaptations. However, the conus arteriosus and its valves, key components of the heart and blood circulation, have been underexplored in phylogenetic and ecomorphological contexts.

Beyond wound sealing: A dual‐functional adhesive nanofiber membrane promoting coagulation and osteogenesis in extraction sites

BMEMat, EarlyView.
Inspired by the suction mechanics of octopus suckers, a dual‐layer nanofiber membrane integrates antibacterial protection, strong wet adhesion, and osteogenic support, offering a bioinspired strategy for effective hemostasis and alveolar bone preservation.

Transient outward K+ current (ITO) reduction prolongs action potentials and promotes afterdepolarisations: a dynamic-clamp study in human and rabbit cardiac atrial myocytes [PDF]

, 2012
Background and aim: Human atrial transient outward K+ current (ITO) is decreased in a variety of cardiac pathologies, but how ITO reduction alters action potentials (AP) and arrhythmia mechanisms is poorly understood, owing to non-selectivity of ITO ...

Abnormal Left Atrial Pump Strain in Patients with Proximal Left Circumflex Coronary Artery Occlusion among Patients with ST-elevation Acute Coronary Syndrome

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging
Background: The left circumflex coronary artery (LCx) is the predominant source of blood supply to the left atrium. This study investigated whether discernable differences in left atrial strain exist among patients with ST-elevation acute coronary ...

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Right atrial strain in atrial fibrillation: the hidden side of the moon

Frontiers in Cardiovascular Medicine
IntroductionLeft atrial (LA) remodeling in atrial fibrillation (AF) is well studied, whereas right atrial (RA) alterations remain poorly characterized. This study evaluates bi-atrial strain dynamics in patients with AF undergoing catheter ablation (CA).MethodsA total of 56 consecutive patients undergoing AF ablation were prospectively evaluated using ...

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.
