migratory birds are most often responsible for the distribution of avian diseases in different areas and serve as hosts for most parasites, including ectoparasites. the aim of the present study was to record the distribution range of a mesostigmatic mite species, dermanyssus gallinae in barn swallow nests in urmia suburb, north west of iran. the samples were collected from 161 bird nests in 44 ...
The pharyngeal swallow can be elicited as an isolated event but, in normal animals, it occurs within the context of rhythmic tongue and jaw movement (RTJM). The response includes activation of the multifunctional geniohyoid muscle, which can either protract the hyoid or assist jaw opening; in conscious nonprimate mammals, two bursts of geniohyoid EMG activity (GHemg) occur in swallow cycles at ...
OBJECTIVE Anastomotic leakage is a serious complication following total pharyngolaryngectomy (TPL) and free jejunal transfer (FJT). Although routine radiological assessment using contrast swallow is widely performed postoperatively for the detection of anastomotic leakage before oral intake, the accuracy remains unclear. We evaluated the clinical usefulness of routine contrast swallow for scree...
This study examined the effects of three swallow maneuvers: (1) the supraglottic swallow (voluntary closure of the vocal folds prior to the swallow); (2) the super-supraglottic swallow (airway closure at the level of the arytenoid to base of epiglottis); and (3) the Mendelsohn maneuver (voluntary prolongation of laryngeal elevation and cricopharyngeal opening during swallow) on swallow function...
Diseases affecting pulmonary mechanics often result in changes to the coordination of swallow and breathing. We hypothesize that during times of increased intrathoracic pressure, swallow suppresses ongoing expiratory drive to ensure bolus transport through the esophagus. To this end, we sought to determine the effects of swallow on abdominal electromyographic (EMG) activity during expiratory th...
