Problem: Alterations of the architecture of cerebral white matter in the developing human brain can affect cortical development and result in functional disabilities. A line scan diffusion-weighted magnetic resonance imaging (MRI) sequence with diffusion tensor analysis was applied to measure the apparent diffusion coefficient, to calculate relative anisotropy, and to delineate three-dimensional fiber architecture in cerebral white matter in preterm (n = 17) and full-term infants (n = 7). To assess effects of prematurity on cerebral white matter development, early gestation preterm infants (n = 10) were studied a second time at term. In the central white matter the mean apparent diffusion coefficient at 28 wk was high, 1.8 microm2/ms, and decreased toward term to 1.2 microm2/ms. In the posterior limb of the internal capsule, the mean apparent diffusion coefficients at both times were similar (1.2 versus 1.1 microm2/ms). Relative anisotropy was higher the closer birth was to term with greater absolute values in the internal capsule than in the central white matter. Preterm infants at term showed higher mean diffusion coefficients in the central white matter (1.4 +/- 0.24 versus 1.15 +/- 0.09 microm2/ms, p = 0.016) and lower relative anisotropy in both areas compared with full-term infants (white matter, 10.9 +/- 0.6 versus 22.9 +/- 3.0%, p = 0.001; internal capsule, 24.0 +/- 4.44 versus 33.1 +/- 0.6% p = 0.006). Nonmyelinated fibers in the corpus callosum were visible by diffusion tensor MRI as early as 28 wk; full-term and preterm infants at term showed marked differences in white matter fiber organization. The data indicate that quantitative assessment of water diffusion by diffusion tensor MRI provides insight into microstructural development in cerebral white matter in living infants.
Solution: Microstructural development of human newborn cerebral white matter assessed in vivo by diffusion tensor magnetic resonance imaging.
Explanation: This title is appropriate for the given abstract because the focus of this abstract is cerebral white matter assesment.

Problem: CD4 memory T cells surviving in the absence of MHC class II contact lose their characteristic memory function. To investigate the mechanisms underlying the impaired function of memory T cells in the absence of MHC class II molecules, we analyzed gene expression profiles of resting memory T cells isolated from MHC class II-competent or -deficient hosts. The analysis focused on five transcripts related to T cell activation, metabolism, and survival that are underexpressed in resting memory T cells from MHC class II-deficient hosts compared with MHC class II-competent hosts. CD4 memory cells isolated from MHC class II-deficient hosts display alterations in their degree of differentiation as well as metabolic activity, and these changes are already manifest in the effector phase despite the presence of Ag-expressing dendritic cells. Our data suggest that the absence of interactions with noncognate MHC class II molecules compromises the progressive accumulation of signals that ensure optimal survival and fitness to sustain the metabolic activity of activated T cells and shape the functional capacity of the future memory compartment. Signals via AKT coordinate survival and metabolic pathways and may be one of the crucial events linking interaction with MHC class II molecules to the successful generation of a long-lived functional memory CD4 T cell population.
Solution:
Noncognate interaction with MHC class II molecules is essential for maintenance of T cell metabolism to establish optimal memory CD4 T cell function.
