Macrophage-epithelial interactions in pulmonary alveoli. [PDF]

Semin Immunopathol, 2016
Alveolar macrophages have been investigated for years by approaches involving macrophage extraction from the lung by bronchoalveolar lavage, or by cell removal from lung tissue. Since extracted macrophages are studied outside their natural milieu, there is little understanding of the extent to which alveolar macrophages interact with the epithelium, or

Tuberculosis: oral alveolus and pulmonary alveoli coexisting. [PDF]

BMJ Case Rep, 2014
Tuberculosis of the oral cavity is uncommon in this antibiotic era. We report a case of a long standing non-healing ulcer of the right upper maxillogingival sulcus, found to be tuberculosis of a rather unusual site in the oral cavity, the alveolus.

Increased pulmonary blood flow leads to alveolar dysplasia during the early postnatal developmental stage [PDF]

Cell & Bioscience
Background Increased pulmonary blood flow (IncPBF), one of the most important features of many children with congenital heart diseases, is well-known as a prerequisite for the induction of pulmonary arterial hypertension.

Pulmonary Surfactant Function in Alveoli and Conducting Airways [PDF]

Canadian Respiratory Journal, 1996
Surface tension plays a very important role in aeration of the neonate's lungs. Pulmonary surfactant, which is inadequate in the premature infant, modifies surface tension during the act of breathing and is necessary for maintenance of alveolar stability.

ABSORPTION FROM THE PULMONARY ALVEOLI [PDF]

Journal of Experimental Medicine, 1947
Experiments upon dogs anesthetized with nembutal and lasting 4 hours, in which the right lymphatic duct and thoracic duct have been cannulated and collection of lung lymph and blood specimens was accomplished after intratracheal instillation of dog plasma, purified bovine serum albumin, crystallized egg albumin, and hemoglobin, have shown that the ...

Microparticle Transport and Sedimentation in a Rhythmically Expanding Alveolar Chip

Micromachines, 2022
Understanding the mechanism of particle transport and sedimentation in pulmonary alveolus is important for deciphering the causes of respiratory diseases and helping the development of drug delivery.

Hydrodynamic Cleansing of Pulmonary Alveoli [PDF]

SIAM Journal on Applied Mathematics, 2002
The inside wall of the pulmonary alveolus is lined with a thin viscous fluid layer and a monolayer of surfactants. Inhaled foreign particles that reach the lung alveoli are normally neutralized by macrophages and remain inside the lung. Based on the suggestion that a hydrodynamic cleansing mechanism may exist in which particles are swept out by the net

Alveolar adenoma: A rare lung tumor [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2007
Introduction Alveolar adenoma belongs to the group of benign epithelial tumors. Histogenesis of alveolar adenoma is a combination of proliferation of alveolar pneumocytes and fibrous tissue originating from septal mesenchyma.

Histo-Morphology Study of the Respiratory Portion of Goat Lung (Capra Hircus) in Baghdad Province

مجلة الانبار للعلوم البيطرية, 2021
The Histo-mrphology were directed on the pneumonic alveoli of 6 male goats. The respiratory portion is composed of typical cuboidal epithelial cells with Clara cell, however, alveolar ducts are lined by simple squamous epithelium and alveoli were ...

Three Alveolar Phenotypes Govern Lung Function in Murine Ventilator-Induced Lung Injury

Frontiers in Physiology, 2020
Mechanical ventilation is an essential lifesaving therapy in acute respiratory distress syndrome (ARDS) that may cause ventilator-induced lung injury (VILI) through a positive feedback between altered alveolar mechanics, edema, surfactant inactivation ...
