Aspiration of radiolucent dentures in facial trauma: Case report.

Foreign body aspiration is a serious problem that may lead to complications or even death. People who sustain major maxillofacial trauma can often damage their teeth or oral prostheses, and aspiration can occur. Detection of this type of aspiration can be difficult, especially in elderly people wearing dental appliances, since many dental prostheses are not radiopaque and the aspiration is not always recognized at the time of injury.

Effects of bombesin and gastrin-releasing peptide on human bronchial epithelial cells from a series of donors: individual variation and modulation by bombesin analogs.

Human pulmonary neuroendocrine cells produce a variety of hormones, including mammalian bombesin (BN) or gastrin-releasing peptide (GRP). Neuroendocrine cell hyperplasia and increased release of BN-like peptides occur in several diseases of the airways, including chronic obstructive pulmonary disease (COPD) and bronchopulmonary dysplasia. Growth stimulation of human bronchial epithelial cells by BN, as measured in a colony-forming assay, has been reported previously (Willey et al.
