ONTOGENESIS OF MURINE NEURAL CREST DERIVATIVES
The neural crest is an epithelial domain within the neural and non-neural ectoderm. This domain is generated along the anterior-posterior axis-giving rise to many different cell types. The key difference between cranial and trunk neural crest is the ability of cranial neural crest to give rise to …

The Ontogenesis of Counterfactual Emotions: Regret and Relief
The aim of the present work is to investigate the development of counterfactual emotions in children aged 3 to 10. More specifically, this work deals with the development of the emotions of regret and relief. Five studies were conducted to determine at which age children start to understand, to …

Ontogenesis of the cornea and ciliary body : a morphological and molecular study
The anterior segment of the eye includes the cornea, lens, iris, ciliary body and trabecular meshwork, with each of these elements playing a vital role in the maintenance of vision. The primary objective of this research is to contribute towards the understanding of how specific genes control …

Ontogenesis of Peptide Transport and Morphological Changes in the Ovine Gastrointestinal Tract
… possibly blood-borne, and may be involved in the ontogenesis of oPepT1. Peptide transport appears to be a physiologically important process in the young lamb and the rumen appears to be involved in the transport of peptides, particularly in nursing lambs.

UNVEILING HUMAN NATURAL KILLER CELLS ONTOGENESIS IN HOMEOSTATIC CONDITIONS AND DURING THE IMMUNE RECONSTITUTION AFTER HAPLOIDENTICAL HEMATOPOIETIC STEM CELL TRANSPLANTATION
… advances in the classification of ILCs, their ontogenesis remains to date uncertain. Many notions come from murine models, but precise orthologous phenotypical markers often lack, as well some developmental intermediates, likely stimulus microenvironment driven. In fact, the generation of ILCs …

The Social Ontology of Psychiatry: Psychiatric Diagnosis as an Ontogenetic, Interpellative Speech Act
… In psychiatric diagnosis, this illocution is ontogenesis, or the instantiation of an individual as a member of a social kind. Because of how this kind is embedded in a social structure, this ontogenetic illocution also results in the perlocutionary effect of interpellation, where a person is …

Composition of cuticular wax on the leaves of kalanchoe daigremontiana
… the wax, determine how these changed during leaf ontogenesis, and discover how they were distributed within the cuticle. Analysis of extracted cuticular wax by gas chromatography, mass spectrometry, and comparison with authentic standards led to the identification of triterpenoids including …

Modeling The Fluid To Solid Transition In Cement Paste, Mortar, And Concrete
… growth models are applied to mechanisms such as ontogenesis, chemical reactions, ecological systems (such as population growth or predator-prey relationship), and so on. In this specific research the models correlate an internal growth mechanism with a variety of externally observable outcomes …

Post-larval development in deep-sea echinoderms
… of adult populations. The post metamorphic ontogenesis of thirty species of deep-sea echinoderms, belonging to three classes (Ophiuroidea, Asteroidea and Echinoidea), is described using scanning electron microscopy. The life history of Ophiocten gracilis is also examined as a case study for …

Aquatecture : underwater dwellings and sea born structures as paradigms of design
… basis for sea dwellings. Developed from an ontogenesis into criteria for environmental design, siting, energy options and program ethics, a platform for establishing a sea utilization framework is imparted. The structural design development incorporates fundamental considerations for aqueous …

The Problem of Guilt: Heidegger, Merleau-Ponty, Fanon, and Glissant
… suggests a particular understanding of moral ontogenesis that has not been read in Merleau-Ponty’s late work on nothingness and the inhuman. In the last two chapters, the dissertation then turns to more recent interpretations of this strand of thinking on guilt in Martinique, Algeria, and the …

Bat Skull Evolution: the Impact of Echolocation
… muscles might mould the skull shape during ontogenesis of oral emitting species: the correlation between peak frequency and shape may result from an indirect mechanical effect. Interestingly, the skull shape of some non-insectivorous species (i.e., frugivorous phyllostomids) also shows an …

Quantifizierung von GAP-43 und die postnatale Entwicklung der molekularen Komplexität im auditorischen Hirnstamm der Ratte
Aus klinischen Studien mit Patienten, die wegen einer kongenitalen Taubheit mit einem Cochlea-Implantat versorgt wurden, weiß man, dass das Alter des Patienten ein wichtiger Faktor für das Langzeitergebnis ist. Als Grund für ein besseres Ergebnis bei jüngeren Kindern werden sensible Phasen in der …

Ontogeny of Venom Use and Venom Composition in the Western Widow Spider Latrodectus Hesperus
<p>I investigated the behavioral ecology of venom and venom use by the western widow spider (Latrodectus hesperus), emphasizing the role of ontogeny. In an introductory paper, I reviewed existing definitions of venom and poison, and refined these by adding a third category of toxic biological …
