We previously reported that men with schizophrenia had reduced volumes of the posterior nasal cavity bilaterally. Since the nasal cavities develop in conjunction with both the palate and ventral forebrain, this could represent a simple marker of embryological dysmorphogenesis contributing to schizophrenia. The current study expands on this finding by ...

Ag and Ag(2)S nanocrystals (NCs) were synthesized by a simple 'one-step' process. Dodecanethiol played three important roles in the synthesis: as the capping reagent, reducer (for the synthesis of Ag) and S(2-) source (for the synthesis of Ag(2)S). Due to the multifunctional characteristic of dodecanethiol, only two reactants (silver nitrate ...

Research demonstrates that varying sensory input, including the characteristics of a bolus, changes swallow physiology. Altering the consistency of fluids is a common compensatory technique used in dysphagia management to facilitate change. However, it is not known what variations in viscosity can be perceived in the oral cavity or oropharynx ...

Age-associated loss of olfactory function, or presbyosmia, has been described in many studies of olfactory ability. Presbyosmia has been ascribed to idiopathic causes despite recognition that many neurodegenerative diseases also induce loss of olfactory function and increase in incidence in the aged population. Often this olfactory loss is unnoticed or ...

Cricopharyngeal bars are commonly seen on a barium swallow radiologic examination and represent the failure of the cricopharyngeus to relax. Traditionally, the bars have been considered as functional or physiologic protrusions. Recently, anatomical cricopharyngeal protrusion has been found in about 30% of cadavers of the elderly, suggesting that such a ...

BACKGROUND: While the mechanism of aerophagia remains unclear, the frequency of clenching has been reported to be increased when under stress. We hypothesized that, via the swallowing reflex, chronic air swallowing was induced through a "learned habit" of the oral cavity, which was acquired through psychological factors. This study examined ...

CONCLUSIONS: A paradoxical relationship between objective and subjective measures of nasal obstruction exists in participants not exposed to any treatment. The sensation of nasal obstruction may be due to the amalgamation of many different nasal sensations. Improved methods for measuring nasal sensations are required to further investigate the relationship between ...
