The chest x-ray in delayed presentation of coarctation of the aorta [PDF]

open access: yes, 2014
This article shows the chest radiograph of a thirteen-year-old male. The study demonstrates bilateral notching of the inferior borders of the 3rd-8th posterior ribs, a finding associated with coarctation of the aorta.

Fibulin-4 is essential for maintaining arterial wall integrity in conduit but not muscular arteries [PDF]

open access: yes, 2017
Homozygous or compound heterozygous mutations in fibulin-4 (FBLN4) lead to autosomal recessive cutis laxa type 1B (ARCL1B), a multisystem disorder characterized by significant cardiovascular abnormalities, including abnormal elastin assembly, arterial ...

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 ...

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

open access: yesBMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

Atherothrombosis and Oxidative Stress: Mechanisms and Management in Elderly [PDF]

open access: yes, 2017
Significance: The incidence of cardiovascular events (CVEs) increases with age, representing the main cause of death in an elderly population. Aging is associated with overproduction of reactive oxygen species (ROS), which may affect clotting and ...

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

open access: yes, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.
