(1) Alveoli underlying the plasma membrane sometimes contain binding sites, particularly on their outer membranes.
(2) These changes led to a flooding of the alveoli with up to 40 times normal protein levels and a greater than fivefold increase in airway antiproteinase.
(3) This suggests that the curvature of the xenon clearance curve is the result of recording the summation of the activities from the alveoli and the pulmonary blood and not, as previously described, due to the existence of two different sub-populations of alveoli.
(4) At 1 week after infection, mycoplasma cells were found in large numbers in the bronchi at the surface of bronchial epithelial cells and, in smaller numbers, in the alveoli where active phagocytosis by polymorphonuclear leukocytes (PMN) occurred.
(5) Within the lung, deposition favored the inner zone (assumed to contain the larger airways) over the outer zone (assumed to be dominated by smaller airways and alveoli).
(6) The interstitium between alveoli is invaded with lymphocytes, macrophages, plasma cells and fibroblasts.
(7) An automatic image analyser was used to monitor pathological changes in morphological structure, especially the size and distribution of collagen fibres, the thickness of the septa and the diameters of alveoli in the lung.
(8) These convective streaming motions combine with molecular diffusion to produce augmented diffusion which transports O2 and CO2 between the trachea and the peripheral alveoli.
(9) The expression of WAP appears to be dependent upon the formation of the alveoli-like spheres: prevention of sphere formation by fixation or drying of the matrix abolishes the expression of WAP.
(10) The aim of this study was to investigate the possibility of determination of lung changes in congenital deformity of heart and vessels by the method of Weibel and Elias (1967) for count of points in the lung (volume of alveoli and interstitium).
(11) Free filoviral particles were seen in pulmonary alveoli and renal tubular lumina, which correlates with epidemiological evidence of droplet and fomite transmission.
(12) These data show that alveoli do not experience the same large swings in pressure as the proximal airway does during liquid breathing and that simple measurements of mPaw can be used to approximate mPA during liquid breathing.
(13) It was hypothesized that pathogenic Pasteurella spp and other microorganisms in nasal secretions transfer from the nasopharynx into the lungs by draining along the tracheal floor into ventral bronchi, bronchioles, and alveoli, and that pasteurella endotoxin, formed in infected lobules, thromboses and occludes lymphatics, capillaries, and veins and thereby causes ischemic necrosis.
(14) We measured pressure excursions at the airway opening and at the alveoli (PA) as well as measured the regional distribution of PA during forced oscillations of six excised dog lungs while frequency (f[2-32 Hz]), tidal volume (VT [5-80 ml]), and mean transpulmonary pressure (PL [25, 10, and 6 cm H2O]) were varied.
(15) After inhalation, the radioactive particles adhere to the walls of the respiratory bronchioli and alveoli.
(16) It is divided into longitudinal zones of arterial distribution; it is broken along primary septal margins into primary alveolar units; within alveoli, it is functionally divided by distortion over circum-alveolar smooth muscle bundles.
(17) Because maximum expiratory flow-volume rates in normal subjects are dependent on gas density, the resistance between alveoli and the point at which dynamic compression begins (R(us)) is mostly due to convective acceleration and turbulence.
(18) The air and fluid collection develops between two layers of the pulmonary ligament following trauma to the lung and rupture of alveoli adjacent to the pulmonary ligament.
(19) The alveolar walls showed variable degrees of thickening and fibrosis, intimal proliferation of alveolar capillaries, and "epithelialization" of alveoli.
(20) They provide a monomolecular lipid film of dipalmitoyl phosphatidylcholine (DPPC) on the surface of lung alveoli to lower surface tension necessary for optimal gas exchange and a hydrophobic protective lining against environmental influences.
Thecodont
Definition:
(a.) Having the teeth inserted in sockets in the alveoli of the jaws.
(a.) Of or pertaining to the thecodonts.
(n.) One of the Thecodontia.
Example Sentences:
(1) The greatest variations in tooth attachment have originated in acrodont bony fishes and in pleurodont reptiles, whereas the selection for a single thecodont or socketed type was an important event in the evolution of mammals.
(2) On the basis of the comparative histology of periodontal tissues, protoacrodontal, acrodontal, acro-protothecodontal, pleurodontal and thecodontal structures can be distinguished that depend upon the area of attachment (crestal, marginal or socketed type) and the mode of attachment (ankylosis, fibrous or combined type).
(3) As in the thecodont mammals, the compressive biting (= occlusal) force is transformed into a tensile force by the tooth-fixing apparatus and by the shapes of the jaws and this is sustained by fibrous structures.
