... attributed to retention of saliva and are usually accompanied by swelling and pain when a salivary stimulus is applied. Mucoceles can be differentiated into mucus extravasation phenomenon or mucus escape reaction, mucus retention cysts and ranulas. They result from extravasation of saliva...

..., because inhibition of COX-1 up-regulated COX-2 expression and PGs produced by COX-2 counteracted the deleterious influences of COX-1 inhibition. The intestinal ulcerogenic response to indomethacin (10 mg/kg) was accompanied by decreased Muc2 expression/mucus secretion and increased intestinal motility...

... surface liquid (ASL) volume depletion, delayed mucusclearance, and mucus adhesion to airway surfaces.This pathogeneticsequence results in airway mucus obstruction andsets the stage for chronic airways inflammation and bacterialinfection.These studies demonstrate that mucus transport isa key component...

... potentiators. The superficial lining of sinonasal epithelium is comprised of airway surface liquid (ASL) containing a low viscosity periciliary fluid layer (sol) around respiratory cilia and a superficial mucus (gel) layer, which function to trap and sweep inhaled particles into the digestive tract...

.... It is a complex system composed of very morphologically disparate components, including (i) the mucus layer, (ii) antimicrobial peptides, (iii) a paracellular epithelial cell barrier, and (iv) a transcellular epithelial cell barrier, which synergize to perform a barrier function. The proinflammatory cytokine TNF...

... Abstract Mucosa-associated lymphoid tissues (MALT) play a critical role as inductive sites for the initiation of antigen-specific protective immunity against pathogens penetrating the mucus membranes. Nasopharynx-associated lymphoid tissue (NALT), situated at the bottom of the rodent nasal...

..., bronchoscopy provides clinically useful information. Bronchoscopy allows direct airway inspection or potential pathogenic micro-organism isolation, whereas repeated lavage may be beneficial for mucus plug removal; foreign-body removal is therapeutic and may be even life saving. The anatomy of the ML bronchus...

...) are large heterogeneous macromolecules, containing oligosaccharide chains attached to peptide backbones encoded by several MUC genes. Hypersecretion of mucus is a common characteristic of airway inflammation. Mucin differs in the sugar groups and the extent of sialylation and sulfation...

... viscous mucus, impaired mucociliary clearance and chronic inflammation/infection of the sinonasal cavity. While some individuals with CF can appear relatively asymptomatic in terms of their sinus disease, commonly reported symptoms include anosmia, headache, facial pain, nasal obstruction, chronic...

... ( a ) and expiration ( b ). Note the significantly reduced area of the lumen during inspiration but the near-complete closure of the lumen during the expiratory phase. Tracheo-oesophageal fistula of the H type (arrows). a An H-type fistula may present as an open or mucus-filled orifice with a bar...
