In 20 normal and four anosmic participants, instantaneous inhalation and exhalation flow rates were recorded in response to 15 s stimulations with clean air or propionic acid concentrations (0.16, 1.14, 8.22 and 59.15 p.p.m., v/v) that ranged from pe

The purpose of this study was to examine the influence of acoustic and perceptual factors of speech on listeners’ perceived hypernasality in the vowel [i]. The isolated syllable [pi] produced by 22 children with hypernasal speech and 6 noncleft chi

A technique was developed to obtain continuous measurements of both respiratory behavior and nasal patency in response to well-controlled odorant stimulation. An automated apparatus similar to that described by Walker et al. (27) was used to present

A two-part study was conducted to determine the sources of variation in nasalance scores derived from the Nasometer. In Study #1, a function generator was used as a signal source to calibrate and input sine and square waves directly into the Nasomete

Commercially prepared glucagon added in μmolar quantities to reticulocyte lysates caused a concentration-dependent depression in the cell-free translation of globin mRNA. Nuclease activity and non-specific protein effects are ruled out as explanatio
