Example input: 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.
Example output: Microstructural development of human newborn cerebral white matter assessed in vivo by diffusion tensor magnetic resonance imaging.
Example explanation: This title is appropriate for the given abstract because the focus of this abstract is cerebral white matter assesment.
Q: OBJECTIVE Genes encoding the circadian transcriptional apparatus exhibit robust oscillatory expression in murine adipose tissues. This study tests the hypothesis that human subcutaneous adipose-derived stem cells (ASCs) provide an in vitro model in which to monitor the activity of the core circadian transcriptional apparatus. RESEARCH METHODS AND PROCEDURES Primary cultures of undifferentiated or adipocyte-differentiated ASCs were treated with dexamethasone, rosiglitazone, or 30% fetal bovine serum. The response of undifferentiated ASCs to dexamethasone was further evaluated in the presence of lithium chloride. Lithium inhibits glycogen synthase kinase 3, a key component of the circadian apparatus. Total RNA was harvested at 4-hour intervals over 48 hours and examined by real-time reverse transcription polymerase chain reaction (RT-PCR).
RESULTS Adipocyte-differentiated cells responded more rapidly to treatments than their donor-matched undifferentiated controls; however, the period of the circadian gene oscillation was longer in the adipocyte-differentiated cells. Dexamethasone generated circadian gene expression patterns with mean periods of 25.4 and 26.7 hours in undifferentiated and adipocyte-differentiated ASCs, respectively. Both rosiglitazone and serum shock generated a significantly longer period in adipocyte-differentiated ASCs relative to undifferentiated ASCs. The Bmal1 profile was phase-shifted by approximately 8 to 12 hours relative to Per1, Per3, and Cry2, consistent with their expression in vivo. Lithium chloride inhibited adipogenesis and significantly lengthened the period of Per3 and Rev-erbalpha gene expression profiles by >5 hours in dexamethasone-activated undifferentiated ASCs. DISCUSSION These results support the initial hypothesis and validate ASCs as an in vitro model for the analysis of circadian biology in human adipose tissue.
