Although the precise cause of PDD-NOS is unknown, abnormalities in certain structures and in neuronal signaling pathways in the brain have been implicated.
It is also found in certain structures of annelids, mollusks, and other invertebrate groups (e.g., jellyfishes, bryozoans, nematodes, and acanthocephalans).
"This man has put in certain structures which are certainly illiberal, anti-democratic, and his passing does not mean that they no longer survive," said blogger Alex Au. "Effort is still needed to dismantle them".
Early trauma has been found to cause changes in certain structures in the brain as well as alterations in chemical activity and these changes can result in heightened reactivity and impaired relational capacity (Phillips and Shonkoff, 2000).
There have been many reports to date of the effects of seemingly small, non-linear, autoparametric interactions in certain structures undergoing forced vibration, and it is known that large intermodal exchanges of energy can occur under several prescribed internal resonance conditions.
The researchers claim that the volume of grey matter in certain structures of the brain affects how susceptible a person is to marketing placebo effects, and that this varies by individual.
These results suggest PCP and apico-basal polarity may be coordinately regulated in certain structures by adhesion proteins.
We have also examined the possibility that a relaxation of purifying selection in certain structures might have been mistaken for positive selection.
It is one of the most widely distributed neurochemicals in the mammalian nervous system, making its precise functions difficult to pinpoint; however, serotonin is more concentrated in certain structures than others.
Expression of Pkm2 is ubiquitous in the CNS but is elevated in certain structures such as the ventricular zone that lines the left ventricles and the inferior colliculus of the midbrain.
