This suggests that in contrast to asthma, in which goblet cell hyperplasia is present in the lower respiratory tract, mucus hypersecretion in pediatric chronic sinusitis may involve other secretory cells, eg, submucosal glandular cells, and mucins secreted by these glandular cells.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/000348940511401212","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:40:52Z","timestamp":1412347252000},"page":"958-965","source":"Crossref","is-referenced-by-count":16,"title":["Immunohistochemical Analyses of MUC5AC Mucin Expression in Sinus Mucosa of Children with Sinusitis and Controls"],"prefix":"10.1177","volume":"114","author":[{"given":"Maria T.","family":"Pe\u00f1a","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawandeep K.","family":"Aujla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kantilal M.","family":"Patel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George H.","family":"Zalzal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary C.","family":"Rose","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2005,12,1]]},"reference":[{"key":"bibr1-000348940511401212","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-6665(20)30795-7"},{"key":"bibr2-000348940511401212","doi-asserted-by":"publisher","DOI":"10.1016\/S1043-1810(06)80010-2"},{"key":"bibr3-000348940511401212","doi-asserted-by":"publisher","DOI":"10.2500\/105065897781751857"},{"key":"bibr4-000348940511401212","doi-asserted-by":"publisher","DOI":"10.3109\/00016488409130975"},{"key":"bibr5-000348940511401212","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200102000-00010"},{"key":"bibr6-000348940511401212","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199711000-00017"},{"key":"bibr7-000348940511401212","first-page":"L413","volume":"263","author":"Rose MC","year":"1992","journal-title":"Am J Physiol"},{"key":"bibr8-000348940511401212","unstructured":"Rose MC, Voynow JA.
