    Nyckelord :adrenaline; adrenoceptors; beta-adrenoceptors; calcium; carbon dioxide; catecholamines; chemiluminescence; exhaled; gadolinium chloride; high frequency oscillatory ventilation; nitric oxide; pulmonary; pulmonary circulation; stretch; sympathoadrenal; veratrine;

    Sammanfattning : Nitric oxide is involved in pulmonary vascular and bronchial regulation and appears to be of paramount importance in the adaptation of the pulmonary circulation at birth. Nitric oxide is present in exhaled gas. LÄS MER

  3. 2. Exploring inter- and intra-heterogeneity in childhood neuroblastoma and pheochromocytoma

    Författare :Wenyu Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroblastoma is the most common extra-cranial solid tumor of the sympathoadrenal cell lineage, which is a unique pediatric malignancy with remarkable inter- and intra-tumoral heterogeneity. In infants, neuroblastoma can regress spontaneously without treatment, while in older patients, neuroblastoma can develop with lethal progression with less than a 50% survival rate. LÄS MER

  4. 3. Therapeutic and prognostic strategies in neuroblastoma : exploring nuclear hormone receptors, MYC targets, and DIAPH3

    Författare :Ye Yuan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroblastoma (NB) is a pediatric cancer derived from the cells of neural crest origin that form the sympathoadrenal system. Typically, the tumor cells migrate along the spinal cord and spread to the chest, neck, and/or abdomen. LÄS MER

  5. 4. Novel aspects of neuroblastoma : to hypoxia and beyond

    Författare :Isabelle Westerlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroblastoma (NB) is a pediatric cancer arising from the neural crest cells forming the sympathetic nervous system. Just as other types of pediatric cancer the driving mutations of neuroblastoma are few and the tumors are instead categorized according to genetic abbreviations such as amplification, loss of heterozygosity, gains and translocations.

  7. 5. Sleep disordered breathing : Natural evolution and metabolism

    Författare :Ahmed Elmasry; Uppsala universitet; []
    Nyckelord :Medical sciences; snoring; sleep apnea; epidemiology; obesity; diabetes; catecholamines; hypertension; evolution; population-based; prospective; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Sleep disordered breathing is manifested by snoring and repeated episodes of apneas and hypopneas. The induced hypoxia and sleep fragmentation are thought to be responsible for many metabolic disturbances.In 1984, 3,201 men aged 30 to 69 answered a questionnaire on snoring, sleep disorders and somatic diseases. In 1994, 2,668 of the survivors (89. LÄS MER
