Aortic valve disease: Novel animal models for advancing our understanding of the underlying mechanisms

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Due to the complex pathophysiology of aortic valve disease (AVD) and the resulting lack of effective pharmacotherapy, existing animal models are valuable research tools, but each has its own strengths and limitations. This review systematically surveys the major AVD models, compares their induction methods, pathological features, advantages and ...

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Age‐Associated B Cells Contribute to Inflammation Via Antibody‐Independent Mechanisms in Takayasu Arteritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Although Takayasu arteritis (TAK) is not a prototypical autoantibody‐mediated disease, accumulating evidence suggests that B cells are involved. This study aimed to investigate the pathway of B cell activation and its contributions to TAK pathogenesis. Methods Histologic analysis of paravascular lymph nodes and affected arteries was conducted

Transcatheter Aortic Valve Implantation (TAVI): Is It Time for this Intervention to be Applied in a Lower Risk Population?

open access: yesClinical Medicine Insights: Cardiology, 2014
Patients with severe aortic stenosis are sometimes not candidates for conventional open heart surgery because of severe deconditioning, excessive risk factors, and multiple comorbidities.
