OBJECTIVES To analyze immediate and long-term results of balloon dilation for aortic coarctation in a three-center experience in Mexico, and to determine factors associated with increased risk. BACKGROUND Results demonstrated that the procedure is effective and safe, however its use in some groups is still controversial, specially in neonates and infants. METHODS In a ten-year period, 333 p...
A rooted planar map is a connected graph embedded in the 2-sphere, with one edge marked and assigned an orientation. A term of the pure lambda calculus is said to be linear if every variable is used exactly once, normal if it contains no β-redexes, and planar if it is linear and the use of variables moreover follows a deterministic stack discipline. We begin by showing that the sequence countin...
Fibroblast growth factors (FGFs) are secreted molecules that activate the RAS/mitogen-activated protein kinase (MAPK) signaling pathway. In zebrafish development, FGF signaling is responsible for establishing dorsal polarity, maintaining the isthmic organizer, and cardiac ventricle formation. Because several ETS factors are known transcriptional mediators of MAPK signaling, we hypothesized that...
We have identified a novel Iroquois (Iro) gene, iro7, in zebrafish. iro7 is expressed during gastrulation along with iro1 in a compartment of the dorsal ectoderm that includes the prospective midbrain-hindbrain domain, the adjacent neural crest and the trigeminal placodes in the epidermis. The iro1 and iro7 expression domain is expanded in headless and masterblind mutants, which are characteriz...
