Different feeding-related behaviors in Aplysia require substantial variations in the coordination of movements of two separate body parts, the lips and buccal mass. The central pattern generators (CPGs) and motoneurons that control buccal mass movements reside largely in the buccal ganglion. It was previously thought that control of the cerebral neuronal circuitry and motoneurons that generate ...
Buccal delivery involves the administration of the desired drug through the buccal mucosal membrane lining of the oral cavity.The objective of this article is to review buccal drug delivery by discussing the structure and environment of the oral mucosa and highlighting the mechanisms of drug permeation and methodology in evaluating buccal formulations. This review also highlights a brief descri...
This study aimed to test the sterility of new unused orthodontic buccal tubes received from manufacturers. Four different types of buccal tubes were used straight from the manufactures package without any additional sterilizing step. Of these buccal tubes tested, three genera of bacteria, implicated as opportunistic pathogens, namely Micrococcus luteus, Staphylococcus haemolyticus and Acinetoba...
This study was to investigate the efficiency of buccal dosage forms to deliver poor orally absorbed drugs. Two buccal gel formulations containing two gastrokinetic drugs with low oral bioavailability; domperidone and mosapride citrate; were tested against their market products. Twenty-four volunteers were enrolled in this study divided into two groups in a single dose, two treatment and two per...
Human buccal cells display diverse changes that are associated with smoked and smokeless tobacco, and clinicopathologic studies have correlated human buccal cell changes with oral cancer. Reported herein are the results of studies that were undertaken to identify a high-throughput technology that would advance efforts to use human buccal cells. We report that (a) a relatively large (mean +/- SD...
Movements of the hyobranchial apparatus in reptiles and amphibians contribute to many behaviors including feeding, lung ventilation, buccopharyngeal respiration, thermoregulation, olfaction, defense and display. In a semi-aquatic turtle, Platysternon megacephalum, x-ray video and airflow measurements from blowhole pneumotachography show no evidence that above water hyobranchial movements contri...
OBJECTIVES/HYPOTHESIS To determine whether buccal squamous cell carcinoma has worse overall survival (OS) and disease-specific survival (DSS) than cancers in the rest of the oral cavity. STUDY DESIGN Retrospective analysis of a large population database. METHODS We began with a Kaplan-Meier analysis of OS and DSS for buccal versus nonbuccal tumors with unmatched data, followed by an analysi...
In the traditional view of vertebrate lung ventilation mechanisms, air-breathing fishes and amphibians breathe with a buccal pump, and amniotes breathe with an aspiration pump. According to this view, no extant animal exhibits a mechanism that is intermediate between buccal pumping and aspiration breathing; all lung ventilation is produced either by expansion and compression of the mouth cavity...
Reported herein are the results of a structured literature review that was undertaken to (a) determine if human buccal (mouth) cell changes are associated with smoking and smokeless ("chewing") tobacco, (b) tabulate different buccal cell alterations that have been reported, (c) delineate buccal cell assays that have been used successfully, (d) determine whether buccal cell changes correlate wit...
