Although a large proportion of individuals with autism manifest abnormal development from birth, a subset of at least 20 30% experience a regression with onset between 18 and 24 months of age after a period of apparently normal development (Lainhart et al. 2002).
At puberty, the phenotype of these individuals changes to a more normal male pattern manifested by development of a functional penis, deepening of the voice, muscle development, etc.
Taking into account everything mentioned above, we suppose that the increase in responses of the STN cells to dural electrical stimulation, observed in the second phase of the orofacial formalin test, can be a result of changes in neuronal excitation, i.e. manifest the development of central sensitization.
Photodynamic therapy produced a good local response in CT26 tumours as manifested by development of oedema followed by a circumscribed black eschar and a marked reduction in tumour size lasting until day 18.
HR is associated with defenses that are highly manifested by development of rapid cell death.
This was usually manifested by development and persistence of microbiologically documented fungal infections or persistence of fever.
A potential explanation given for the different cellular stress phenotypes in GH dwarfs, methionine-restricted and CR mice was that epigenetic changes leading to cellular stress resistance may be manifested during development, rather than postnatally (Harper et al., 2006).
In fact, the macromelanosomal phenotype displays variable expressivity in vitro and in vivo (34, 35) and, at least in the mouse, manifests during development subsequent to optic misrouting, implying that it might represent only an epiphenomenon of the disease (27).
The novelty of this crop in cell biology research has been manifested through development of robust cytogenetic and mutation stocks to decipher the cellular and metabolic events leading to plant growth, development, and stress tolerance [ 26– 28].
However, whether this negative bias can be considered as a risk factor, manifested before the development of a depressive episode, or is a consequence of suffering from depression, remains unclear.
