Epimorphisms between 2-bridge link groups: Homotopically trivial simple loops on 2-bridge spheres [PDF]

open access: yes, 2011
We give a complete characterization of those essential simple loops on 2-bridge spheres of 2-bridge links which are null-homotopic in the link complements. By using this result, we describe all upper-meridian-pair-preserving epimorphisms between 2-bridge

Myocardial bridging

open access: yesBrazilian Journal of Cardiovascular Surgery, 2015
Myocardial bridging is rare. Myocardial bridges are most commonly localized in the middle segment of the left anterior descending coronary artery. The anatomic features of the bridges vary significantly. Alterations of the endothelial morphology and the vasoactive agents impact on the progression of atherosclerosis of myocardial bridging.
