Mediante disección y microscopia óptica se estudió el tracto digestivo de imagos de Lagocheirus plantaris indistinctus, Dillon, 1957 (Coleoptera: Cerambycidae). Estos escarabajos presentan el estomodeum inicia en la cavidad ...

Among anuran embryonic structures, the adhesive (cement) glands appear posterolaterally to the stomodeum and produce a mucous secretion that adheres embryos to surfaces in and out of the egg. In this paper, we study the ...

The morphological, cytological and physiological aspects of the digestive tract of the siarid Bradysia impatiens fourth-instar larvae were studied using bright-field microscopy. The division of the digestive tract into the ...

Eukaryotic translation initiation factor 5A (eIF5A) has a unique character: the presence of an unusual amino acid, hypusine, which is formed by post-translational modifications. Even before the identification of hypusination ...

This survey examined the association between the hyperiid amphipod Hyperoche martinezii and ctenophores off the Argentinian coast (38°08′17″S, 57°31′18″W) through the evaluation of seasonality, prevalence and intensity of ...

Although the external larval morphology of many species of Microhylidae has been characterized, ontogenetic studies in the family are scarce and partial. In the present study, we describe the development of the oral funnel, ...

Among anuran embryonic structures, the adhesive (cement) glands appear posterolaterally to the stomodeum and produce a mucous secretion that adheres embryos to surfaces in and out of the egg. In this paper, we study the ...

O crânio dos vertebrados, uma das aquisições evolutivas mais recentes, é formado por duas populações de células, uma delas derivada do mesoderma e outra das células da crista neural (CN). Elementos do crânio derivados das ...

Entre las estructuras embrionarias de los anuros, las glándulas adhesivas (o de cemento) aparecen posterolaterales al estomodeo y producen una secreción mucosa que adhiere los embriones a las superficies dentro y fuera del ...
