Purpose: The aim of this study was to examine the influence of menstrual cycle phases (follicular, ovulatory, luteal, and ischemic) and hormone levels (estradiol, testosterone, progesterone, and neuropeptide Y) on vocal fold vibrations in reproductive and postmenopausal women. Method: Glottal area waveforms were extracted from high-speed…

The percentage of children with certain allergic conditions has increased over previous decades. Seasonal allergies, which includes hay fever, allergic rhinitis, and allergic conjunctivitis, causes sneezing, cough, runny nose, and itchy eyes. Eczema, also known as atopic dermatitis, causes itchy, bumpy rashes and thickened skin that can appear…

Purpose: The goal of this study was to present vocal aerodynamic measurements from pediatric and adult participant pools. There are a number of anatomical changes involving the larynx and vocal folds that occur as children age and become adults. Data were collected using two methods of noninvasive aerodynamic assessment: mechanical interruption…

Purpose: The aim of the study was to update our information regarding the salpingopharyngeus (SP) muscle using cadaveric and in vivo magnetic resonance imaging (MRI) data. Primary objectives were to (a) observe the presence/absence of the muscle and (b) quantify and describe its dimensions and course. Method: SP specimens from 19 cadavers (10…

Purpose: The larynx plays a role in swallowing, respiration, and voice production. All three functions change during ontogeny. We investigated ontogenetic shape changes using a mouse model to inform our understanding of how laryngeal form and function are integrated. We understand the characterization of developmental changes to larynx anatomy as…

Purpose: Most acoustic and articulatory studies on /l/ have focused on either duration, formant frequencies, or tongue shape during the constriction interval. Only a limited set of data exists for the transition characteristics of /l/ to and from surrounding vowels. The aim of this study was to examine second formant (F2) transition…

Individuals who register as body donors do so for various reasons, with aiding medical science a common motivation. Despite awareness of several key reasons for donation, there are few in-depth explorations of these motivations to contextualize persons' reasons for donating. This study undertakes a mixed-method exploration of motivations for body…

Purpose: The objective of the current study was to investigate the effects of age and vocal loading on the respiratory and laryngeal systems. Method: Fourteen younger (M = 20 years) and 13 older (M = 75 years) healthy individuals participated in a 40-min vocal loading challenge in the presence of 70-dB background noise. Respiratory kinematic and…

Purpose: This study evaluated the accuracy of respiratory calibration methods for estimating lung volume during speech breathing. Method: Respiratory kinematic data were acquired via inductance plethysmography in 32 young adults, 22 older adults, and 13 older adults with Parkinson's disease (PD). Raw rib cage (RC) and abdomen (AB) signals (V) were…

This research was conducted to determine whether there are differences between the norm values used in the evaluation of children who train in different sports and physical education lessons according to the chronological age and biological age of the children. The research group consists of a total of 239 male students of 13 (n=116) and 14…

Composing Territory is a research project with two main aims. The first aim is to identify optimal composition and arrangement techniques for choral works written for female singers from various linguistic backgrounds in the Northern Territory whose voices are undergoing pubertal changes. The second aim is the creation of twelve choral…

In order to monitor training effects and physical developments in elite sports, it may be beneficial to perform anthropometric measurements and physical fitness tests regularly. In this study, the relationship between the anthropometric properties and physical fitness values of elite figure skating athletes were investigated. 21 elite athletes in…

Background: Older age is a risk factor for low bone mineral density (BMD). Older women have been found to have lower BMD than younger women. Recent trends for decreased calcium consumption and physical activity may place younger women at greater risk than previously anticipated. Purpose: The purpose of this study was to evaluate the effect of age…

The present study examined the concurrent and prospective, longitudinal effects of childhood negative emotionality and self-regulation on allostatic load (AL), a physiological indicator of chronic stress. We hypothesized that negative emotionality in combination with poor self-regulation would predict elevated AL. Mothers reported on children's…

Purpose: Identifying and addressing poor nutritional status in school-aged children is often not prioritized relative to HIV/AIDS treatment. The purpose of this paper is to elucidate the benefits of integrating nutrition (assessment and culturally acceptable food supplement intervention) in the treatment strategy for this target group.…
