Structural and functional vocal fold epithelial integrity following injury.
OBJECTIVES/HYPOTHESIS An intact epithelium is an important part of vocal fold defense. Damage to the epithelium can compromise vocal fold homeostasis and protection of the host tissue from viral and bacterial invasion. Elucidating the effects of damage on epithelial architectural and barrier integrity provides insight into the role of epithelium in protecting vocal folds. Using an animal model,...

Cytoskeleton of newborn vocal fold stellate cells.
OBJECTIVES/HYPOTHESIS Vocal fold stellate cells (VFSCs) in the human maculae flavae located at both ends of the vocal fold mucosa are inferred to be involved in the metabolism of extracellular matrices of the vocal fold mucosa. Tension caused by phonation (vocal fold vibration) likely regulates the behavior of the VFSCs in the human maculae flava. Tensile and compressive strains have direct eff...
متن کاملA novel hybrid method for vocal fold pathology diagnosis based on russian language
In this paper, first, an initial feature vector for vocal fold pathology diagnosis is proposed. Then, for optimizing the initial feature vector, a genetic algorithm is proposed. Some experiments are carried out for evaluating and comparing the classification accuracies which are obtained by the use of the different classifiers (ensemble of decision tree, discriminant analysis and K-nearest neig...
متن کاملThe Effects of Size and Type of Vocal Fold Polyp on Some Acoustic Voice Parameters
Background: Vocal abuse and misuse would result in vocal fold polyp. Certain features define the extent of vocal folds polyp effects on voice acoustic parameters. The present study aimed to define the effects of polyp size on acoustic voice parameters, and compare these parameters in hemorrhagic and non-hemorrhagic polyps.Methods: In the present retrospective study, 28 individuals with hemorrha...
