In obstruent consonants, a major constriction in the upper vocal tract yields an increase in intraoral pressure (P(io)). Phonation requires that subglottal pressure (P(sub)) exceed P(io) by a threshold value, so as the transglottal pressure reaches the threshold, phonation will cease. This work investigates how P(io) levels at phonation offset ...

Drugs acting on cardiovascular (CV) prevention are, by definition, interconnected with age-induced arterial changes. However, this question has been poorly investigated along long-term treatment. This goal requires a major prerequisite: to determine statistical links associating age-induced changes in arterial stiffness and wave reflections with drug classes acting on CV prevention. ...

Aim:  Baroreflex control of the bronchial circulation is unresolved. Early studies suggested that baroreflexes dilate or have no effect, but recent studies in awake dogs suggested baroreflexes did not normally engage tonic vasoconstrictor efferents but during excitement systemic pressure rises may also trigger local sensory-motor dilator reflexes. We examined the ...
