THE ROLE OF E6 PROTEIN IN HUMAN PAPILLOMAVIRUS ASSOCIATED UPPER AIRWAY DISEASES
Infection of the upper aero-digestive tract with low-risk and high-risk human papillomaviruses is the cause of recurrent respiratory papillomatosis and a subset of head and neck cancers, respectively. E6 protein is considered one of the oncoproteins encoded by high-risk HPVs, due to its ability to …

A computational neuromuscular model of the human upper airway with application to the study of obstructive sleep apnoea
… apnoea. The anatomy of the tongue and other upper airway tissues, and the ability to model their behaviour, is central to such investigations. In this thesis, details of the construction and development of a three-dimensional finite element model of soft tissues of the human upper airway, as …

Sleep Apnea Equipment’s for Obstructive Sleep Apnea
… apnea is caused due to recurrent episodes of upper airway obstruction during sleep that is caused by elevations in upper airway collapsibility during sleep. The underlying anatomic alterations and disturbances in upper airway neuromuscular control, plays key roles in the pathogenesis of …

A size and shape analysis in obstructive sleep apnea patients
… is related to an abnormal configuration of the upper airway. Since it presupposes a complex pathogenesis, studies on the disease usually require the analysis of many variables. This makes it difficult to obtain an adequate sample size. Further, the size of the upper airway structure often …

Effects of the Lubo cervical collar on airway patency in awake adults – A magnetic resonance imaging study
… mechanism. The combination enables non-invasive airway management in cases of trauma where cervical motion restriction is necessary. The potential benefits include use as an airway adjuvant maintaining upper airway patency, reducing provider task loading. The limited research on the device …

Aspects of laryngotracheobronchitis in African children
… is a relatively recent term for infective upper airway disease (Baum, 1924). Prior to this "croup" was used by both public and profession to describe a train of laryngeal symptoms which sometimes were due to infection. The word derives from the Anglosaxon "kropan" (Neffson and Wishik, …

Possible Influences of Vowel Tongue Position on Vocal Fold Stiffness
… possibility of the results being obtained due to upper airway stiffness or oral-pharyngeal resistance (as opposed to vocal fold stiffness alone) was considered and discussed.

The Effects of Untreated and Treated Obstructive Sleep Apnoea on Subjective Sleepiness, Microsleeps, Simulated Driving Performance and Neurocognitive Functioning
… disorder of neural respiratory control and upper airway dysfunction that results in repeated complete and partial occlusion of the upper airway during sleep. Obstructive sleep apnoea has been linked to fatigue, increased rates of road and work-related accidents and deficits across a range of …

Feasibility of Individualized Airway Surgery in Horses
… models in the investigation of multiple upper airway surgeries for recurrent laryngeal neuropathy (RLN) in horses. Overall, the objective was to build the knowledge of laryngeal conformation and fluid mechanics with various surgical procedures for application in patients as an evaluation …

Unstable Ventilatory Control During Sleep After High Spinal Cord Injury: The Contribution Of Chemosensitivity And Hypoventilation
… measurement of ventilation, timing, and upper airway resistance (RUA) on a breath-by-breath basis during transitions from wake to stage N1 sleep. Compared to able-bodied controls, SCI subjects had a significantly greater reduction in tidal volume during the transition from wake to N1sleep …

Mechanical evaluation of a modified prosthetic laryngoplasty using a toggle technique for the equine arytenoid cartilage
… is a frequent cause of poor performance and upper airway noise in horses. This disorder results in varied degrees of upper airway obstruction due to neurogenic atrophy of the cricoarytenoideus dorsalis muscle secondary to degeneration of the recurrent laryngeal nerve. The treatment of choice …

From Systemic to Regional: Personal Health and Medical Monitoring Systems that Adapt to Individual Variance
… monitoring during unsupervised rehabilitation, upper airway obstruction monitoring for obstructive sleep apnea, as well as device and measurement setup customization based on the patient’s regional body physique and use environment.

The Comparison of Airway Responses of Normal Horses Fed Round Bale versus Square Bale Hay
… round bale hay (RBH) has been associated with airway inflammation. The purpose of this study was to determine if horses fed RBH for a 6-week period demonstrated more evidence of airway inflammation than horses fed square bale hay (SBH) of comparable quality. Hypothesis - The respiratory health …

CBCT Analysis of the Pharynx: Effects of Age and Sex
… of the pharyngeal structures practical. The airway is easily imaged because of the large differences in X-ray attenuation between air and the soft tissues that are mostly water. <strong>Purpose</strong>: CBCT images were analyzed in a large (n = 263) cross-sectional sample of routine dental …

EXPLORING EQUINE ASTHMA: PATHOGENESIS INSIGHTS AND DIAGNOSTIC CHALLENGES
… of chronic inflammatory disorders of the lower airway, which can be classified as mild-moderate (MEA) or severe (SEA), based on clinical severity. Although it is spread worldwide and has been studied for decades, gaps persist in our understanding of EA's pathogenesis. This highlights the need …

Peri-extubation practices and extubation failure in a South African tertiary paediatric intensive care unit
… extubations. Indications for re-intubation were: upper airway obstruction (n=7; 33.3%); respiratory failure (n=4; 19.0%); heart failure (n=3; 14.3%); diaphragm paralysis, hypoventilation and cardiac arrest (n=2; 9.5% each); and reduced level of consciousness (n=1; 4.8%). Prematurity (adjusted OR …

Influence of Obstructive Sleep Apnea (OSA) on Rostral Fluid Shift, and the Pathophysiology on Asthma
… of asthma, declined lung function, increased airway hyperresponsiveness, and greater need for asthma medications. Previous studies showed that overnight fluid shift from the legs into the neck and peripharyngeal tissues increases upper airway resistance and severity of OSA. Recent findings …
