Phylogenesis — Ontogenesis — Oncogenesis
Medical Hypotheses, 1989Ontogenesis might be considered as the development of phylogenetically consequent genic systems that mainly imply: homoeotic genes and ras protooncogene in segmentation; ras and myc protooncogenes in gastrulation; ras, myc and other nuclear protooncogenes in organogenesis; ras myc, other nuclear and cytomembrane protooncogenes in growth-differentiation.

Best Practice & Research Clinical Endocrinology & Metabolism, 2010
During the early phases of development, adrenal glands share a common origin with kidneys and gonads. The action of diverse transcription factors, signalling pathways and endocrine signals is required for the individualization of the adrenal primordium and its subsequent differentiation into an adult adrenal gland, with massive remodelling taking place

In recent years it was revealed that in adipose tissue active cell proliferation and an increase of cell number takes place; this process participates in a significant way in the increase of adipose tissue mass during ontogenetic development (1–4). The growth of adipose tissue by hyperplasia of adipocytes can be stimulated in growing animals by some ...

Journal of Speech, Language, and Hearing Research, 1982
Three children were followed longitudinally for 12 months, between their 11th and 22nd months of life, to document their development of the linguistic expression of the agent concept. The children were observed approximately once a month in play and structured activities designed to elicit nonverbal and linguistic behaviors indicative of the children's

Les notions d’héritage darwinien ou de transmission textuelle (J. Kristeva) éclairent le travail de la paraphrase, du plagiat ou du pastiche qui se fait chez Malcolm Lowry à partir de sources variées : livres scolaires de géométrie, d’histoire naturelle, écrivains et poètes.

ONTOGENESIS OF SPONTANEOUS K‐COMPLEXES
Psychophysiology, 1971ABSTRACTThe “spontaneous” K‐complex, an EEG phenomenon, was studied with an explicit rating system. The spontaneous K‐complex can first be identified at age 6 months. Maturation of the K‐complex progresses rapidly for about the first 2 years after birth, then slows, albeit, with increased variability until age 5 years, progressing again until a ...

In examining the ontogenesis of ideas, we consider two types of ideas, the natural and the constructed, which differ as to type of constituting elements and symbolic representation. Not as a corollary of this but as a fundamental difference between these types of ideas, voluntary eidetic motion can be seen as the primary source of constructed ideas ...

Ontogenesis of Cholinesterases
1963Cholinesterases (ChE’s) and particularly acetylcholinesterase (AChE) were early (Loewi and Navratil 1926) associated with rapidly occurring events of neurohumoral or synaptic transmission and with function and motility (BACQ 1935 a). Thus, together with enzymes concerned with adrenergic function, ChE’s are dramatically different from enzymes concerned ...

In the previous chapter, we derived an optimized architecture for multistage routing of visual information. In order to be optimal in terms of number of neural elements, this network needs to have a very specific connectivity (cf. Figure 4.1). If we want to argue that such architectures are actually employed by the brain for information routing (which ...
