Importance of Acute Anterior Angulation in Double Aortic Arch Needing Attention at Primary Surgery
BackgroundVascular rings are rare congenital abnormalities of the aortic arch. There are many embryological variants including a double aortic arch. In symptomatic children, division of ring and release of airway structures may be sufficient. Persistence

Mathematical modeling of local perfusion in large distensible microvascular networks [PDF]
Microvessels -blood vessels with diameter less than 200 microns- form large, intricate networks organized into arterioles, capillaries and venules. In these networks, the distribution of flow and pressure drop is a highly interlaced function of single ...

Patent Arterial Duct and Vascular Ring in a Premature Infant
We report a case of a 750 grams premature female who was scheduled for surgical ligation of a patent arterial duct. Intra-operative findings showed a patent arterial duct in association to a retro-esophageal aortic arch creating a complete vascular ring

Tetrahydrobiopterin analogues with NO-dependent pulmonary vasodilator properties [PDF]
Reduced NO levels due to the deficiency of tetrahydrobiopterin (BH4) contribute to impaired vasodilation in pulmonary hypertension Due to the chemically unstable nature of BH4 it was hypothesised that oxidatively stable analogues of BR, would be able to ...

Characterization of pediatric aortic arch vascular rings
Background Vascular rings (VRs) are rare congenital anomalies of the aortic arch. Along with clinical data, several imaging techniques help to suspect VR. Flexible fiberoptic bronchoscopy (FFB) is also considered the main tool for diagnosis.

Reversal of aging-induced increases in aortic stiffness by targeting cytoskeletal protein-protein interfaces [PDF]
BACKGROUND: The proximal aorta normally functions as a critical shock absorber that protects small downstream vessels from damage by pressure and flow pulsatility generated by the heart during systole.
