  2. 2. Superior Underwater Vision in Humans

    Författare :Anna Gislén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; taxonomy; zoogeography; Zoologisk systematik; djurgeografi; Systematic zoology; contrast sensitivity; spatial vision; Accommodation; pupil;

    Sammanfattning : Amphibious vision is accomplished in many animals by special optical and physiological adaptations in the eyes. However, human eyes are considered to be adapted to a life in air since our curved outer cornea – which is used to refract more than two-thirds of the incoming light on land – becomes useless underwater.

    Sammanfattning : Acute thrombo-embolic occlusion of the superior mesenteric artery (SMA) with intestinal infarction is a lethal disease, difficult to diagnose in time, with unknown incidence and cause-specific mortality. The aim of this thesis was to characterize the disease and to develop diagnostic methods. LÄS MER

  4. 4. The laryngeal mucosa and the superior laryngeal nerve of the rat : an immunohistochemical and electron microscopic study

    Författare :Siw Domeij; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Superior laryngeal nerve; paraganglia; substance P; calcitonin gene-related peptide; neuropeptide Y; vasoactive intestinal polypeptide; enkephalin; mast cells; electron microscopy; immunohistochemistry;

    Sammanfattning : Neuropeptides are present in nerve fibers of the upper and lower airways. Local release of these substances may be of importance for the pathophysiology of airway disorders and may play a role in responses to different stimuli. However, little is known about the distribution of neuropeptides in the larynx. LÄS MER
