Ontogeny of early life immunity [PDF]
The human immune system comprises cellular and molecular components designed to coordinately prevent infection while avoiding potentially harmful inflammation and autoimmunity. Immunity varies with age, reflecting unique age-dependent challenges including fetal gestation, the neonatal phase, and infancy.

Journal of Fish Biology, 2004
The early development of sunbleak Leucaspius delineatus, from activation of ovum to juvenile, was recorded using both living and preserved materials. Five embryonic steps, one free embryo and five larval steps were identified. Hatching occurred between 73 h 25 min and 85 h 25 min (post‐activation); the free embryo period was extremely short in duration

The early ontogeny of human–dog communication
Animal Behaviour, 2008Although dogs, Canis familiaris, are skilful at responding to human social cues, the role of ontogeny in the development of these abilities has not been systematically examined. We studied the ability of very young dog puppies to follow human communicative cues and successfully find hidden food.

Early ontogeny of face grooming in mice
Developmental Psychobiology, 1985AbstractA U‐shaped function of behavioral growth characterizes the early ontogeny of face grooming in mice. In the first few postnatal days (0–100 hr), mice groom their face by using temporally isolated strokes, or bouts of strokes, which vary in amplitude and symmetry.

Ontogeny of the early hominid face
Journal of Human Evolution, 1989Abstract New approaches to the study of early hominid mineralised tissue biology have been developed and it is now possible to investigate actual growth mechanisms responsible for the development of fossil bones and teeth. Dynamic features of skeletal morophogenesis in ontogeny and phylogeny can thus be described.

Early Placental Ontogeny in the Mouse
Placenta, 2002Fundamental to placental morphogenesis is union between the allantois and the chorion, two tissues initially separated in the conceptus. Results of previous studies in the mouse have suggested that chorio-allantoic union is driven by the developmental maturity of the allantois and involves molecular interactions between Vascular Cell Adhesion Molecule (

Primacy of Action in Early Ontogeny
Human Development, 1998(1937/1954). The article of Muller and Overton provides a hum-bling reexamination of this critique, bringing back to us how much has been thoughtand is accounted for in the monumental work Piaget left behind. But who can afford athorough reading of Piaget in the current ‘publish or perish’ culture of academia?

The early ontogeny of blastoids
Geological Journal, 2005AbstractBlastoids (phylum Echinodermata; class Blastoidea) pass through a stage during growth in which the oral surface of the minute theca is composed of five oral plates only. The evidence that these thecae, which lack hydrospires, deltoids and lancet plates, are juvenile blastoids is that they occur together with mature blastoids and vice versa ...
