Further reanalysis defined the spine subregion from the top of the thoracic spine to the top of the pelvis and laterally to the bone/soft tissue interface, and BMC, BA, and BMD were calculated for this subregion.
Superimposition of the OAS1 and cGAS 3D structures in complex with the nucleic acid molecule indicated that the S11 residue of OAS1 perfectly matches S163 of cGAS; both residues were positively selected in primates or Homininea and define the N-terminus of the "spine" helix.
For the spatial correspondence, local coordinate systems of both (i.e., coordinate systems defined by each system an x-axis defined by the pelvis and a y-axis defined by the spine) are rotated about the y-axis into a global coordinate system (i.e., an absolute coordinate system newly defined for the coordinate system matching a subject always faces the front) (Figure 2).
Further studies are required to define the connections between the cervical spine and headache in children.
Longitudinal studies are required to define the role of the cervical spine in the development or maintenance of pain in children with CTTH.
Next, the binary mask defined by the spine is dilated with a horizontal structuring element, and the outcome is used as a mask for separating cardiac structures from the posterior part of the chest wall (since the process described in Subsection 2.1.3 does not remove the lower part of the image).
The longest among all these shortest paths was defined as the spine of skeleton.
Markers were also attached to the spinous process of the 7th cervical vertebrae (C7), jugular notch, L5/S1, bilateral iliac crests, and bilateral posterior superior iliac spines, in order to define the trunk and pelvis.
In addition, progress in defining the biochemical basis of spine development and stabilization may yield insights into mental retardation and psychiatric disorders.
