BRISC-an open source pulmonary nodule image retrieval framework.

We have created a content-based image retrieval framework for computed tomography images of pulmonary nodules. When presented with a nodule image, the system retrieves images of similar nodules from a collection prepared by the Lung Image Database Consortium (LIDC). The system (1) extracts images of individual nodules from the LIDC collection based on LIDC expert annotations, (2) stores the extracted data in a flat XML database, (3) calculates a set of quantitative descriptors for each nodule that provide a high-level characterization of its texture, and (4) uses various measures to determine the similarity of two nodules and perform queries on a selected query nodule.

A central giant cell granuloma influenced by pregnancy.

A case of a 17-year-old patient with exacerbation of a central giant cell granuloma of the mandible during pregnancy is reported. The possible relationship of the giant cell lesion to a pre-existing fibrous dysplasia is considered although there was lack of histological evidence.

Regional cerebral blood flow and cerebral metabolic rate of oxygen during hyperventilation in the newborn dog.

Cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) were measured during normocarbia and during both moderate and severe hypocarbia. Eighteen newborn mongrel dogs, 1 to 7 days of age, were given pancuronium and ventilated with 70% N2O and 30% O2. The respirator was adjusted to achieve a PaCO2 of 15 torr, all subsequent changes to 25 and 40 torr were made by adjusting the inspired concentration of CO2.

Lack of anion effect on volume expansion natriuresis in the developing canine kidney.

The renal response to volume expansion with sodium chloride or sodium bicarbonate was studied in 15 newborn and 13 adult dogs. Proximal and distal nephron function were estimated using the technique of distal nephron blockade. Fractional sodium reabsorption was 99.
