Antioxidant enzymes reduce DNA damage and early activation of valvular interstitial cells in aortic valve sclerosis.
OBJECTIVE Accumulation of reactive oxygen species (ROS) and remodeling of the microstructure of the cusp characterize aortic valve sclerosis, the early phase of calcific aortic valve disease. These events are associated with activation of valvular interstitial cells (VICs) toward an osteogenic-like phenotype. Because ROS cause DNA damage and transcriptional activation we investigated the relati...

متن کاملComparison of cardiac function and valvular damage in children with and without adenotonsillar hypertrophy.
OBJECTIVE Comparison of cardiac function in children with and without adenotonsillar hypertrophy. METHODS We examined 28 pediatric patients with adenotonsillar hypertrophy mean aged 7.3+/-2.9 years comprised of 14 females and 14 males (group I). The control group were chosen from 35 healthy sex and age matched children mean aged 7.37+/-2.7 years (group II). Both groups were examined by an oto...
متن کاملValvular Disease
Methods: Magnetic Resonance Imaging of cardiac valves requires state of the art equipement such as a 1.5 or 3 Tesla magnet and a surface coil. Three principal sequences are required [1]: 1) Black blood, 2) cine steady state free precession (CineSSFP), and 3) phase contrast velocity encoded cine (VENCine). Black blood images are obtained by preparation of a fast spin echo sequences with a nonsel...
متن کاملValvular endothelial cells and the mechanoregulation of valvular pathology.
Endothelial cells are critical mediators of haemodynamic forces and as such are important foci for initiation of vascular pathology. Valvular leaflets are also lined with endothelial cells, though a similar role in mechanosensing has not been demonstrated. Recent evidence has shown that valvular endothelial cells respond morphologically to shear stress, and several studies have implicated valvu...
