A novel rat model of pulmonary artery embolism and the application value of lung ultrasound B‐lines in early‐stage pulmonary embolism

Animal Models and Experimental Medicine, EarlyView.
We report a novel embolus‐induced PE rat model prepared via the inferior vena cava under ultrasound guidance. The embolus employed featured a tubular plastic casing filled with thrombus. By minimizing the contact surface between plasmin and thrombus, it effectively restrains the elevated plasmin activity in rats.

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

Animal 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 ...

Age Is an Effect Modifier of Thrombectomy Benefit in a Socioeconomically Vulnerable Stroke Population

Annals of Neurology, EarlyView.
Objective Randomized trials from high‐income countries have shown that endovascular treatment (EVT) yields similar benefits in elderly and non‐elderly patients with large vessel occlusion stroke (LVOS). However, evidence from low/middle‐income countries remains scarce.

Safety and Feasibility of Magnetic Separation‐Based Blood Purification

Advanced NanoBiomed Research, EarlyView.
We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...

Norepinephrine release in the heart atria of diabetic rats.

General physiology and biophysics, 2004
The content, release and uptake of norepinephrine (NE) in the sympathetic nerves of the rat heart atria were studied in the course of diabetes and in age-matched controls. Diabetes was induced by streptozotocin (STZ) and rats were subjected to further experiments 1, 4 or 7 months later (STZ1, STZ4, STZ7).

Heart Atria Granularity Effects of Changes in Water-Electrolyte Balance

Experimental Biology and Medicine, 1979
SummaryAtrial granularity was measured using a new morphometric method in rats subjected to procedures known to alter water-electrolyte balance. It was found that water deprivation and sodium deficiency lead to atrial hypergranulation, whereas, the combined administration of desoxycorticosterone (2.5 mg/100 g body wt/day) and 2% NaCl in the drinking ...

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Cardioneuroablation for Drug Refractory Vasovagal Syncope After COVID-19 Infection

JACC: Case Reports
Cardioneuroablation is a novel approach to treat patients with recurrent vasovagal syncope (VVS), targeting the ganglionated plexi around the atria and thus reducing the vagal input to the heart.

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Left Atrial Myxoma Following Coronary Artery Bypass Grafting with Patient Coronary Arterial Grafts: a Rarity

Brazilian Journal of Cardiovascular Surgery
The development of left atrial myxoma after coronary artery bypass graft surgery is a rare entity. A 60-year-old man with previous off-pump coronary artery bypass grafting four years ago with patent coronary grafts was diagnosed with left atrial mass ...
