(15) The method involves the delivery of fresh gas to the respiratory tree during expiration, thereby flushing out the anatomic deadspace and ensuring that the gas initially delivered to the alveolus with the succeeding inspiration is able to participate in gas exchange.
(16) This rare malignancy occurred in the maxillary alveolus, appearing as an epulis.
(17) Surgical repair of the lip is done within the first 2 months of life, by the time the nose, alveolus and projecting prolabium are adequately reformed.
(18) These data are consistent with exogenous cholesterol being rapidly esterified in the alveolus, and the ester then being cleared by the macrophages.
(19) Because macrophages and epithelial cells are in close physical contact within the alveolus, we measured the eicosanoids produced by combined cultures of these cells.
(20) The aim of this study was to compare permanent tooth length development in children with complete unilateral clefts of the lip, alveolus, and palate (UCLP) with that of tooth length development in a normal reference population.

(3) These results indicated that the PG determination was the most accurate predictor of fetal lung well-being prior to birth among the clinical tests so far reported.
(4) Morphological alterations in the lungs of pheasants after prolonged high-dosage administration of bleomycin sulfate were studied by light and electron microscopy.
(5) When perfusion of the affected lung was less than one-third of the total the tumour was found to be unresectable.
