Mucous retention cysts are the most common disorder of the minor salivary glands. An occlusion of the ducts of the minor salivary glands can lead to retention of mucus, and this change can in turn cause cyst formation. They are most commonly encountered in the lower labial mucosa but can affect any part of the oral mucosa and the involvement of the soft palate is rare. Salivary mucoceles may be...
The apocrine and sebaceous scent glands of ringtailed lemurs (Lemur catta) appear to serve different social functions. In behavioral experiments, lemurs modulate their responses to scent marks based on the type of odorant, their own physiological state, the signaler's physiological state, and prior social experience. To examine variation in odorant chemistry relative to olfactory behavior, we u...
The labial gland of adult workers of the ant Pachycondyla obscuricornis is made up of many acini, each consisting of one central cell surrounded by approximately 10 parietal cells. Both cell types are associated with a system of ramified canaliculi that remove the secretion towards a ductule outside the acinus. These ductules, each associated with one acinus, fuse together and form a ramified s...
BACKGROUND Primary Sjögren's syndrome (pSS) is a common chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands and peripheral lymphocyte perturbation. In the current study, we aimed to investigate the possible pathogenic implication of autophagy in T lymphocytes in patients with pSS. METHODS Thirty consecutive pSS patients were recruited together with 20 patie...
BACKGROUND The aim of this study was to compare displacements and stress after en masse retraction of mandibular dentition with lingual and labial orthodontics using three-dimensional (3D) finite element models (FEM). METHODS A 3D FEM of each lower tooth was constructed and located as appropriate to Roth's prescription. The 0.018-in. GAC Roth Ovation labial and Ormco 7th Generation lingual br...
Reaction times (RTs) from human orofacial muscles were obtained with labial displacement and auditory stimuli to evaluate the potential for contributions by these sensorimotor processes to speech movement coordination. Because speech requires both concurrent and sequential movements, intramovement (labial stimulus, labial response) and intermovement (labial stimulus, lingual response) RT minima...
Predicting the effects of labial coarticulation is an important aspect with a view to developing an artificial talking head. This paper describes a concatenation approach that uses sigmoids to represent the evolution of labial parameters. Labial parameters considered are lip aperture, protrusion, stretching and jaw aperture. A first formal algorithm determines the relevant transitions, i.e. tho...
