13. Experiments in concept modeling for radiographic image reports.
OBJECTIVE: Development of methods for building concept models to support structured data entry and image retrieval in chest radiography. DESIGN: An organizing model for chest-radiographic reporting was built by analyzing manually a set of natural-language chest-radiograph reports. During model building, clinician-informaticians judged alternative conceptual

14. Multicompartmental Analysis of Calcium Kinetics in Normal Adult Males*
This report describes studies of calcium kinetics in ten normal young men. Serum, urinary, and fecal radioactivity was measured from 1 minute to 20 days after intravenous tracer 47Ca injection, and these results were analyzed jointly with data obtained from a simultaneous metabolic balance study, using digital computer techniques. Surface radioactivity measu

15. Dynamic mapping of human cortical development during childhood through early adulthood
We report the dynamic anatomical sequence of human cortical gray matter development between the age of 4–21 years using quantitative four-dimensional maps and time-lapse sequences. Thirteen healthy children for whom anatomic brain MRI scans were obtained every 2 years, for 8–10 years, were studied. By using models of the cortical surface and sulcal landm

16. The effect of pancreatic polypeptide on glucose disposal after surgical alterations of the pancreas.
Surgical alterations of the pancreas result in anatomic changes that can affect postoperative glucose metabolism. Pancreas transplantation results in reduction of beta-cell mass, systemic release of insulin, and denervation. The authors hypothesized that such alterations affect peripheral glucose disposal to induce an "insensitivity" to endogenously (systemi

17. Steady State Responses: Electrophysiological Assessment of Sensory Function in Schizophrenia
Persons with schizophrenia experience subjective sensory anomalies and objective deficits on assessment of sensory function. Such deficits could be produced by abnormal signaling in the sensory pathways and sensory cortex or later stage disturbances in cognitive processing of such inputs. Steady state responses (SSRs) provide a noninvasive method to test the

18. Th2 responses induced by epicutaneous or inhalational protein exposure are differentially dependent on IL-4
Atopic individuals are predisposed to mounting vigorous Th2-type immune responses to environmental allergens. To determine the factors responsible, animal models that closely mimic natural modes of allergen exposure should prove most informative. Therefore, we investigated the role of IL-4, a known Th2-promoting cytokine, in generation of Th2 responses after

19. Semi-automated Phalanx Bone Segmentation Using the Expectation Maximization Algorithm
Medical imaging technologies have allowed for in vivo exploration and evaluation of the human musculoskeletal system. Three-dimensional bone models generated using image-segmentation techniques provide a means to optimize individualized orthopedic surgical procedures using engineering analyses. However, many of the current segmentation techniques are not cli
