On Branchiostoma californiense (Cephalochordata) from the Gulf of Nicoya estuary, Costa Rica
(Universidad de Costa Rica, 2010)
Population structure of the lancelet Branchiostoma caribaeum (Cephalochordata: Branchiostomidae) in the Baia de Guanabara, Rio de Janeiro, southeastern Brazil
(SOC BRASILEIRA ZOOLOGIA, UNIV FEDERAL PARANA, 2008)
Population structure of the lancelet Branchiostoma caribaeum Sandevall, 1853 was studied in four surveys, corresponding to austral seasons, in a tropical bay, southeast of Brazil. Abundance was higher in the spring and was ...
A new species of sand-dwelling catfish, with a phylogenetic diagnosis of Pygidianops Myers (Siluriformes: Trichomycteridae: Glanapteryginae)
(Sociedade Brasileira de Ictiologia, 2011)
A new species of sand-dwelling catfish genus Pygidianops, P. amphioxus, is described from the Negro and lower Amazon basins. The new species differs from its three congeners in the elongate eel-like body, the short barbels, ...

Bases moleculares de elementos de la cascada de señalización en fotorreceptores microviliares
(2014)
Las opsinas visuales animales han sido agrupadas, basándose en análisis de secuencias, en unas pocas categorías que se relacionan estrechamente con las principales clases morfológicas de fotorreceptores. En particular, ...
Caracterización del receptor de acetilcolina nicotínico (nAChR) en la sinapsis neuromuscular de la especie Branchiostoma lanceolatum
(Universidad de Concepción.Facultad de Ciencias Biológicas, 2023)
La unión neuromuscular (UNM) es la sinapsis periférica entre neuronas motoras y fibras musculares que controla el movimiento coordinado de una gran variedad de organismos. El estudio de la UNM se ha realizado en distintos ...
Was the tail bud the ancestral centre where the fin developmental program evolved in chordates?
(Naturalis Biodiversity Center, 2015)
The structural origin of the vertebrates' paired limbs is still an unsolved problem. Historically, two hypotheses have been raised to explain the origin of vertebrate limbs: the Archipterygium Hypothesis and the Fin Fold ...
Structural shifts of aldehyde dehydrogenase enzymes were instrumental for the early evolution of retinoid-dependent axial patterning in metazoans
(NATL ACAD SCIENCES, 2011)
Aldehyde dehydrogenases (ALDHs) catabolize toxic aldehydes and process the vitamin A-derived retinaldehyde into retinoic acid (RA), a small diffusible molecule and a pivotal chordate morphogen. In this study, we combine ...
