  1. 16. Regional pulmonary vasoreactivity, with special reference to nitric oxide, prostacyclin and body posture

    Författare :Danguolé Rimeika; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Regional pulmonary perfusion; nitric oxide; prostacyclin; NOS-inhibition; COX-inhibition; shunt; one-lung ventilation;

    Sammanfattning : The primary aim of the study was to investigate possible mechanisms behind the improved arterial oxygenation in ventilator-treated patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) when turned into prone position. A secondary aim was to discover new knowledge of possible importance for treatment of patients with oxygenation problems in intensive care and during anesthesia. LÄS MER

  3. 17. Nitric oxide synthase in female reproductive and urinary organs: Hormonal regulation and functional significance

    Författare :Jassim Al-Hijji; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; estrogen; trophoblast; placenta; vagina; Nitric oxide; uterus; ovarian steroids; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : Nitric oxide synthase (NOS) activity was studied in cytosolic and particulate fractions in reproductive organs from rabbit (uterus and vagina) and rat (uterus, vagina and cervix). NOS was found predominantly in cytosolic fractions in all tissues and the activity of NOS in both fractions was highly Ca2+ dependent. LÄS MER

  4. 18. Experimental skin flaps and nitric oxide

    Författare :Örjan Gribbe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Surgical flaps; nitric oxide; ischemia; reperfusion; nitrite; laser Doppler; transit-time ultrasound flowmetry; electron microscopy; NO donors; NOS inhibitors;

    Sammanfattning : Surgical flaps are used in plastic surgery to reconstruct tissue defects due to trauma or cancer removal. Occasionally flaps are subjected to ischemia and reperfusion injury leading to flap failure. LÄS MER

  5. 19. Vulvar vestibulitis syndrome : pathophysiology of the vestibular mucosa

    Författare :Nina Bohm-Starke; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vulvar vestibulitis syndrome; immunohistochemistry; QST; COX 2; NOS; laser Doppler perfusion imaging; intraepithelial nerve fibres; pain thresholds; sensory stimulation.;

    Sammanfattning : Objective: The main purpose of the study was to survey possible pathophysiological changes of the vestibular mucosa in women with vulvar vestibulitis syndrome with regard to the clinical findings of superficial dyspareunia and mucosal erythema. Methods: Biopsies analysed with immunohistochemistry were used to study the morphology, distribution and neuropeptide content of the peripheral nerves, and the microvascularisation of the vestibular mucosa.

  7. 20. Black & white or shades of grey : teachers perspectives on the role of nature of science in compulsory school science teaching

    Författare :Lotta Leden; Lena Hansson; Andreas Redfors; Malin Ideland; Malmö högskola; []
    Nyckelord :Nature of science; teachers perspectives; Didactical questions; Focus groups; Nature of science; School science; Science teaching traditions; Scientific literacy; Teachers’ perspectives;

    Sammanfattning : Avhandlingen utforskar lärares perspektiv och förhandlingar gällande vilken roll “naturvetenskapens karaktär” (engelska ”nature of science”, NOS) kan spela i grundskolans NO-undervisning. Tidigare forskning har visat att NO-undervisning ofta har ett starkt fokus på naturvetenskapliga begrepp och strukturerade laborationer med ett implicit fokus på ”korrekta svar”. LÄS MER
