  1. 21. Neonatal respiratory control : inspiration, inflammation and the prostaglandin E2 pathway

    Author : Veronica Siljehav; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Immature or deficient autonomic control is a common problem in infants born at a premature age, and is of central importance in apneas. The pre- and perinatal development of the brainstem neural circuits that control autonomic functions is vital for survival after birth and for the regulation of breathing movements. READ MORE

  2. 22. Redox Reactions of NO and O2 in Iron Enzymes : A Density Functional Theory Study

    Author : Mattias Blomberg; Per Siegbahn; Adrian Mulholland; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; enzyme catalysis; redox reactions; cytochrome oxidase; nitric oxide reductase; hyponitrous acid anhydride; peroxynitrite; myoglobin; prostaglandin synthase; PGHS; NO; N2O; O2; CO; Chemical physics; Kemisk fysik;

    Abstract : In the present thesis the density functional B3LYP has been used to study reactions of NO and O2 in redox active enzymes.Reduction of nitric oxide (NO) to nitrous oxide (N2O) is an important part in the bacterial energy conservation (denitrification). READ MORE

  3. 23. The prostanoid FP receptor and uveoscleral outflow : A study of FP receptor expression and functions in the eye

    Author : Anette Ocklind; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Prostanoid FP receptor; tissue distribution; ciliary muscle; iris sphincter muscle; extracellular matrix; actin; prostaglandin F2a; latanoprost; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Abstract : Prostaglandin F2α is a prostanoid FP receptor agonist which acts as an intraocular pressure-lowering agent by increasing the uveoscleral outflow of aqueous humour through the ciliary muscle. The aim of this, thesis was to investigate possible mechanisms of the increased uveoscleral outflow induced by prostaglandin F2α and its analogue latanoprost acid. READ MORE

  4. 24. Effects of Inflammatory Mediators on Pulmonary Airways

    Author : Ofir Bachar; Klinisk och experimentell allergiforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electric ?eld stimulation; bradykinin; airway; tumor necrosis factor a; Respiratory system; nitric oxide; Andningsorganen; Toll-like receptor; prostaglandin E2; neurotrophin; allergy;

    Abstract : Chronic inflammation is together with excessive contraction of the airways key features of asthma. The aims of the thesis were to analyze the effect of inflammatory mediators on airway smooth muscle, using an in vitro model of cultured murine airways. READ MORE

  5. 25. Role of Inducible Nitric Oxide Synthase and Melatonin in Regulation of β-cell Sensitivity to Cytokines

    Author : Annika K. Andersson; Stellan Sandler; Nils Welsh; Décio L. Eizirik; Nils Billestrup; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; β-cell; Cyclooxygenase; Cytokine; Diabetes; IFN-γ; IL-1β; iNOS; Insulin; Melatonin; Nitric oxide; Pancreatic islets; Phospholipase D; Prostaglandin E2; Streptozotocin; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : The mechanisms of β-cell destruction leading to type 1 diabetes are complex and not yet fully understood, but infiltration of the islets of Langerhans by autoreactive immune cells is believed to be important. Activated macrophages and T-cells may then secrete cytokines and free radicals, which could selectively damage the β-cells. READ MORE
