The chaos mechanism of above-range phonation was examined in symmetrically modeled vocal folds by using the traditional two-mass model assumption. Poincaré map technique used to display chaotic attractors. This method provided an effective description irregular vocal-fold movements. power spectrum, Lyapunov exponent, and Kaplan-Yorke dimension were employed describe vibrations model. These nonlinear dynamic analyses suggested that, for positive attractors contribute vibrations. Descriptions...
An excised hemilarynx setup was developed. The phonatory characteristics of nine canine larynges were examined. left vocal fold each larynx then removed and substituted with a vertical plexiglass plate. phonated again. Recordings made phonation threshold pressure, sound pressure level, average glottal flow, fundamental frequency, amplitude vibration as observed video stroboscope. Measurements over range subglottal pressures. For the hemilarynx, simultaneous recordings intraglottal contact...
Four vocally untrained healthy adults, 2 men and women, completed the study. A double-blind placebo-controlled approach was used to administer three treatments each participant on separate days. Drugs involved a single 60-mg dose of diuretic, Lasix (LA), one day, 50-mg an oral antihistamine, diphenhydramine hydrochloride (DH), another day. third day administration placebo, sugar pills (SP). Critical posttreatment measures were weight (kg), which estimated systemic dehydration, saliva...
Abstract Objective: In recent years, a growing body of evidence has been reported that tumor clone is organized as hierarchy originates from rare stem cells. CD133, cell surface antigen, was identified maker for human leukemia, brain tumors, and prostate cancer. The purpose this study to detect the expression putative marker cancer cells in Hep‐2 line, isolate CD133 positive observe their proliferation differentiation ability vitro. Method: Immunocytochemical staining technology flow...
: To determine the effect of bolus volume on pharyngeal swallowing using high-resolution manometry (HRM).: Repeated measures with subjects serving as own controls.: Twelve swallowed four volumes in neutral head position: saliva; 5 mL water; 10 and 20 water. Pressure measurements were taken along length pharynx a manometer, emphasis placed velopharynx, tongue base, upper esophageal sphincter (UES). Variables analyzed across three-way repeated analysis covariance (ANCOVA) investigating sex,...
The addition of a fourth type voice to Titze’s classification scheme is proposed. This characterized by primarily stochastic noise behavior and therefore unsuitable for both perturbation correlation dimension analysis. Forty samples were classified into the proposed four types using narrowband spectrograms. Acoustic, perceptual, analyses completed all samples. Perturbation measures tended increase with type. Based on reliability cutoffs, 1 2 voices considered suitable Measures unreliability...
Nonlinear dynamic methods including correlation dimension and Lyapunov exponents are applied to quantitatively analyze phonations in excised larynx experiments. Irregular typically characterized by aperiodic waveforms broadband spectra. Finite dimensions positive of irregular demonstrate the existence chaos phonations. Furthermore, dimension, maximal exponent, jitter, shimmer, peak prominence ratio used statistically distinguish from normal The exponent indicate a significant difference...
Abstract Background Mounting evidence suggests that most tumors consist of a heterogeneous population cells with subset has the exclusive tumorigenic ability. They are called cancer stem (CSCs). CSCs can self‐renew to generate additional and also differentiate phenotypically diverse limited proliferative potential. have been identified in variety tumors. In this study, we identify marker established human laryngeal tumor Hep‐2 cell line vivo. Our vitro experiment shown as CD133,...
Abstract Objectives/Hypothesis: The purpose of this study was to compare the clinical effectiveness type I thyroplasty, injection laryngoplasty, and graft implantation for treatment vocal fold scar pathologic sulcus vocalis. Study Design: Prospective, multi‐arm, quasi‐experimental research design. Methods: Twenty‐eight patients with newly diagnosed and/or vocalis were assigned one three modalities: thyroplasty (n = 9), laryngoplasty ( n 10). Psychosocial, auditory‐perceptual, acoustic,...
Primary human vocal fold mucosal cells recapitulate native physiologic function, offering voice restoration to patients with advanced laryngeal disease.
The effects of exposure to dry air on phonation were measured in an ex vivo model vocal fold vibration. Excised canine larynges mounted apparatus and made phonate at a constant subglottal pressure by means unhumidified airflow. threshold (FTP), glottal airflow, sound intensity the acoustic output, efficiency also assessed. Student's r-test was performed results. In 17 larynges, average PTP increased from 10.0 cm H 2 O 15.0 after airflow (p < .001). addition, flow 585 mL/s 801...
There is an important need for good animal models of the larynx study physiology phonation. The dog's has been used as model more than 2 centuries phonatory research. However, there some evidence that pig advantages over dog a Another readily available deer larynx. In this comparative study, laryngeal anatomy and function were examined in 4 species — human, pig, dog, white-tailed deer. Particular attention was directed to those structures one would predict could affect phonation, from...
