There are two major transport pathways across epithelia: a transcellular pathway through cells and a paracellular pathway between cells. Previous electrophysiological studies in mosquito Malpighian tubules suggested that the neuropeptide leucokinin-VIII (LK-VIII) increases the chloride permeability of the paracellular pathway. To test the effect of LK-VIII(More)
OBJECTIVES/HYPOTHESIS Synchronous tumors are defined as malignancies presenting within 6 months of the index tumors. A significant subset of patients present at initial evaluation with malignant tumors of both the head and neck (head and neck squamous cell carcinoma) and the lung, which are termed simultaneous primaries. The management and treatment(More)
BACKGROUND Rapid reepithelialization of respiratory epithelium after injury to the large conducting airway (eg, trachea and bronchus) is poor. Our laboratory has developed an in vitro model of the trachea that allows us to examine reepithelialization in a complex culture system. We previously described how the presence of cartilage inhibited respiratory(More)
