   Sammanfattning : Colorectal cancer is one of the most common malignant diseases world-wide. Most patients can be diagnosed, staged and treated by surgery in an elective setting. However, about one fifth of the patients will have an emergency presentation and in most cases due to malignant obstruction of the left colon. LÄS MER

3. 2. Exercise-induced laryngeal obstruction : Prevalence, laryngeal findings and evaluation of treatment

   Författare :Katarina Norlander; Leif Nordang; Malin Svensson; Riitta Möller; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; laryngeal obstruction; bronchoconstriction; CLE-score; EILOMEA;

   Sammanfattning : Exercise-induced laryngeal obstruction (EILO) is one of many different causes for adolescents to experience dyspnoea during exercise. Objective exercise-testing with continuous video laryngoscopy is crucial for a correct diagnosis since it is difficult to differentiate EILO from other exercise related conditions in the airways only on the symptomatology.

   Sammanfattning : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. LÄS MER

5. 4. Nasal obstruction – impact on insomnia symptoms and sleep-disordered breathing

   Författare :Caroline Bengtsson; Eva Lindberg; Lars Jonsson; Jenny Theorell-Haglöw; Søren Berg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic rhinosinusitis; CRS; nasal obstruction; sleep; sleep apnoea.; Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

   Sammanfattning : Background: Nasal obstruction is very common in the general population, but the role of nasal obstruction in sleep quality is not clear. Nasal obstruction is also prevalent in patients with obstructive sleep apnoea (OSA) and may contribute to poor adherence to continuous positive airway pressure (CPAP) treatment. LÄS MER

7. 5. Modeling of Hindered Diffusion in Gels

   Författare :Jan Gutenwik; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective diffusion coefficient; pore size distribution; obstruction; immobilization; modeling; adsorption kinetics; hindered diffusion; simulation program; proteins; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : Hindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. LÄS MER
