  2. 1. Axon Guidance and Morphogenesis of the C. elegans Pharynx

    Author : Manish Rauthan; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharynx; M2; C. elegans; extra-cellular matrix ECM ; hex; Krüppel; pha-2; isthmus; NSM; pharyngeal neurons.; cytoskeleton; mnm-2;

    Abstract : The C. elegans pharynx is a single cell thick muscular tube that undergoes morphogenesis to attain it mature structure from a ball of 80 undifferentiated cells. This thesis is about understanding the mechanisms and the genetic pathways underlying the process of pharyngeogenesis. READ MORE

  4. 2. Airway protection and coordination of breathing and swallowing : in health and anesthesia

    Author : Anna I. Hårdemark Cedborg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : pharynx;

    Abstract : Swallowing and breathing is coordinated to ensure that the airway is protected from aspiration. During the pharyngeal phase of swallowing, breathing is interrupted to allow safe passage of bolus. However, details on the complex coordination of breathing and swallowing and their precise temporal relationship are not fully understood. READ MORE

  5. 3. Snoring and Sleep Apnea in Women : Risk Factors, Signs and Consequences

    Author : Malin Svensson; Eva Lindberg; Mats Holmström; Ludger Grote; Uppsala universitet; []
    Keywords : snoring; sleep apnea; women; general population; risk factors; daytime sleepiness; inflammation; pharynx;

    Abstract : Obstructive sleep apnea syndrome (OSAS) is characterized by snoring, apneas and excessive daytime sleepiness (EDS). Obesity is a risk factor for snoring and sleep apnea, but data on other factors in relation to obesity are ambiguous. Symptoms of sleep apnea in women have not been fully elucidated. READ MORE

  6. 4. Nerve lesions in pharynx : an aetiology of obstructive sleep apnoea

    Author : Danielle Friberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : "Heavy snorers disease" is defined as the progression from habitual snoring to obstructive sleep apnoea (OSA). Apart from a significant weight gain, the aetiology underlying progression to a collapse of the upper airways during inspiration and sleep remains unclear. READ MORE

  7. 5. Exploring the role of rheology in bolus flow using an in-vitro approach

    Author : Muhammad Waqas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extensional rheology; ultrasound viscometery; Bolus rheology; in vivo analysis; in vitro manometry; In-vitro simulations; degluitition; microstructure analysis; thickened fluids; Dysphagia;

    Abstract : Swallowing disorders, termed ‘dysphagia’, are more common in the elderly but can also affect younger persons. Approximately, 8% of the world’s population suffers from dysphagia. A Texture Modified Diet (TMD), which increases bolus viscosity to adjust for the sluggish bolus handling mechanism, is the most common intervention. READ MORE
