Aneurisma de arteria coronaria Coronary artery aneurysm

Revista Colombiana de Cardiología, 2005
La dilatación aneurismática, 1,5 veces el diámetro del vaso mayor normal que compromete un segmento de arteria coronaria, es una patología de rara presentación (incidencia 1,5% a 5%).

Antegrade Urethral Approach for Urethral Stricture in Patients with Previous Failed Retrograde Intervention

Translational Research in Urology, 2020
Introduction Urethral stricture has challenging difficulties in its treatment. Various treatment modalities had been used e.g.; urethral dilatation is one of the oldest methods.

Deformations of normed groupoids and differential calculus. First part [PDF]

, 2009
Differential calculus on metric spaces is contained in the algebraic study of normed groupoids with $\delta$-structures. Algebraic study of normed groups endowed with dilatation structures is contained in the differential calculus on metric spaces ...

Closed surface bundles of least volume

, 2010
Since the set of volumes of hyperbolic 3-manifolds is well ordered, for each fixed g there is a genus-g surface bundle over the circle of minimal volume.

Cerebral artery dilatation maintains cerebral oxygenation at extreme altitude and in acute hypoxia—an ultrasound and MRI study

Journal of Cerebral Blood Flow and Metabolism, 2011
Transcranial Doppler is a widely used noninvasive technique for assessing cerebral artery blood flow. All previous high altitude studies assessing cerebral blood flow (CBF) in the field that have used Doppler to measure arterial blood velocity have ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Dilatation Operator and Space-time Geometry

, 2008
We discuss the possibility of defining a dynamical model describing the RG-flow for a Quantum Field Theory. Construction of the dilatation operator is discussed in details for one-vertex one-loop level.Comment: 6 pages.

A Bespoke Programmable Interpenetrating Elastomer Network Composite Laryngeal Stent for Expedited Paediatric Laryngotracheal Reconstruction

Advanced Functional Materials, EarlyView.
A programmable interpenetrating double‐network architecture, created via 3D‐TIPS printing and resin infusion, synergistically combines thermoplastic and thermosetting elastomers to balance structural rigidity and surface softness—crucial for paediatric laryngeal stents.

Nonplanar integrability at two loops

, 2012
In this article we compute the action of the two loop dilatation operator on restricted Schur polynomials that belong to the su(2) sector, in the displaced corners approximation.
