Polysomnography (PSG) is currently considered the gold standard for assessing sleep quality. However, the numerous sensors that must be attached to the subject can disturb sleep and limit monitoring to within hospitals and sleep clinics. If data could be obtained without such constraints, sleep monitoring would be more convenient and could be extended to(More)
The prostaglandin-evoked cAMP production was studied in human neuroblastoma SK-N-BE(2)C cells during neuronal differentiation induced by all-trans retinoic acid. The incubation with 5 microM all-trans retinoic acid for 4-6 days promoted neurite outgrowth of cells. After differentiation, prostaglandin E(2) (PGE(2))-induced cAMP production was dramatically(More)
Intraoral negative pressure during bottle feeding with two kinds of teats (a regular Nuk and a cleft Nuk) was measured in 7 infants with cleft lip and palate, 8 infants with cleft palate, 2 infants with cleft lip, 4 infants with operated cleft lip and palate and 7 normal infants. Infants with cleft lip and palate or cleft palate were unable to generate(More)
The purpose of this study was to evaluate the long-term radiological results obtained with open reduction and fixation of unilateral mandibular condyle fractures in 10 patients. CT images taken at the end of the follow-up period (average of 22 months, range 7 to 33 months), were traced and digitized, and the position and morphology of the fractured condylar(More)
In the case of mandibular angle fractures, a two miniplate fixation technique in which one plate is applied ventral to the oblique line and a second plate at the inferior border of the buccal cortex was used to stabilize the fracture. In this paper, the stability of the two miniplate fixation technique was tested in a three-dimensional in vitro model. The(More)
