  1. 1. Applications of organ culture of the mouse inner ear

    Författare :Diana Berggren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; organ culture; embryonic inner ear; intercellular junctions; aminoglycosides; statoacoustic ganglion; intermediate filaments; collagen; endolymph;

    Sammanfattning : The embryonic mouse inner ear was used as a model with which to study ototoxicity and tissue interactions. The inner ear anlage can be explanted and cultured in vitro from about the 12th gestational day (gd), and will differentiate parallel with the inner ear developing in vivo until a time corresponding to birth (21st gd).

  3. 2. The effects of plasminogen deficiency on the healing of tympanic membrane perforations

    Författare :Annika Hansson; Sten Hellström; Diana Berggren; Tor Ny; Magnus von Unge; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tympanic membrane; macrophages; neutrophils; fibrin ogen ; inflammation; keratinocyte migration; wound healing; uPA; tPA; in vitro; Otorhinolaryngology; Otorhinolaryngologi;

    Sammanfattning : The healing of tympanic membrane (TM) perforations is a complex wound healing process including inflammation, migration of keratinocytes and tissue remodelling. Most TM perforations in human heal spontaneously, however some perforations become chronic, and the reason to why is still largely unknown. LÄS MER

  4. 3. Evaluation of surgical methods for sleep apnea and snoring

    Författare :Thorbjörn Holmlund; Diana Berggren; Eva Levring Jäghagen; Karl Franklin; Sören Berg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sleep apnea syndromes; adverse effects; mortality; radiofrequency; sham surgery; randomized controlled trial; daytime sleepiness; snoring; tonsillar hypertrophy; tonsillectomy; cytoskeleton; desmin; dystrophin; muscle fiber; palatopharyngeus; soft palate; uvula.; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Sammanfattning : Background: Snoring and obstructive sleep apnea (OSA) are both common disorders with a number of negative health effects. The safety and efficacy of treating snoring and OSA surgically have been questioned and there has been a lack of studies in the field. LÄS MER

  5. 4. Silicone obturators and the bacterial flora in symptomatic nasal septal perforations

    Författare :Anna Karin Hulterström; Anders Berglund; Diana Berggren; Åke Davidsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nasal mucosa; perforation; symptomatic; inflammation; Staphylococcus aureus; obturator treatment; medical silicone; wettability;

    Sammanfattning : Background A perforation in the nasal septum can cause symptoms such as bleeding, obstruction, crusts and pain, and can be a challenge to treat. Surgery is the treatment of choice, but disease, size of the perforation, or the patient’s wish may contradict surgery. LÄS MER

  7. 5. Nitric Oxide in the Inner Ear with Particular Regard to Neurotansmission and Pharmacotherapy

    Författare :Raul Popa; Diana Berggren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Medicine; medicin;

    Sammanfattning : Research into nitric oxide (NO) in the inner ear has expanded explosively during recent years. There is evidence that NO is present in the various cochlear structures and its action is involved in physiological mechanisms, such as neurotransmission, and in pathological processes, e.g. ototoxicity.
