Última Micrometric measurement of the density of stained odontoblast processes 47 Kohli,Alicia; Pezzotto,Stella M.; Garcia,Graciela; Poletto,Leonor C.. The embryological, structural and functional unit of the dentine-pulp complex shares the odontoblast, located in the border of the dentine pulp, with basal nuclei and organelles. The odontoblast process emerges from its apical pole. It is formed by microtubules, microfilaments and vesicles covered by membranes penetrating the dentinal tubules, isolated from the inter-tubular matrix, along the extent of the dentine. The objective of this study was to evaluate the efficacy of three staining techniques: hematoxylin-eosin, periodic acid-Schiff and Schmorl, by staining the process, from beginning to end, and compare the results with the erosion technique. Thirty human teeth were employed in the trial; after their extraction the pulp was fixated, the pieces...

El complejo dentinopulpar comparte el odontoblasto cuyo cuerpo está ubicado en la parte externa de la pulpa dentaria. De su polo apical se desprende el proceso odontoblástico que se introduce en el canalículo dentinal atravesando la dentina originando en su recorrido múltiples colaterales hasta su finalización. Describir el proceso fue ardua tarea de investigadores que combinaron técnicas histológicas para preservarlo en el interior de los canalículos utilizando microscopio electrónico de transmisión o scanning para visualizarlo. En un trabajo previo observamos ambos tejidos unidos por los odontoblastos y los procesos coloreados. El objetivo actual fue medir micrométricamente la longitud de procesos y canalículos para verificar si ambas son similares tanto...

Pimelodus albicans Valenciennes, 1840 (common name "moncholo" or "bagre blanco") is an endemic species of the family Pimelodidae in the río de la Plata basin. Phylogenetic approach based on cytochrome b sequences was performed to test the existence of a unique evolutionary lineage in P. albicans and to discriminate populations units or subpopulations related to a migration behavior of this taxon in the río de la Plata basin. This study included 34 samples of P. albicans of different collecting sites in the río de la Plata estuary and in the río Arrecifes belonging to the río Paraná basin. Among 614 base pairs in the cytochrome b sequence data set, 203 were variable and 120 were phylogenetically informative sites in P. albicans. A total of twenty...

ABSTRACT The family Rivulidae is the fourth most diverse clade of Neotropical fishes. Together with some genera of the related African family Nothobranchiidae, many rivulids exhibit a characteristic annual life cycle, with diapausing eggs and delayed embryonic development, which allows them to survive in the challenging seasonal ponds that they inhabit. Rivulidae also includes two species known as the only the self-fertilizing vertebrates and some species with internal fertilization. The first goal of this article is to review the systematics of the family considering phylogenetic relationships and synapomorphies of subfamilial clades, thus unifying information that is dispersed throughout the literature. From this revision, it is clear that phylogenetic... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cynolebiidae; Killifish; Neotropical; Total evidence.
