  1. 11. Blood-and Injection Phobia in Pregnancy : Epidemiological, Biological and Treatment aspects

    Författare :Caroline Lilliecreutz; Ann Josefsson; Gunilla Sydsjö; Lars von Knorring; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-and injection phobia; pregnancy; prevalence; cortisol; outcome; cognitive behavioral therapy; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Introduction: Blood- and injection phobia is an anxiety disorder with a prevalence of approximately 3-5% in the general population. The etiology is often a combination of genetic factors and a conditioning experience. LÄS MER

  3. 12. The role of PDGF-B in brain blood vessels

    Författare :Khayrun Nahar; Christer Betsholtz; Jean-Baptiste Demoulin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFBC; PDGFB; PDGFRB; Brain vasculature; Mural cells;

    Sammanfattning : The development of blood vessels is dependent on several molecular cues to form properly. A functional PDGF-B/PDGFR-b signaling is paramount for the investment of mural cells, that provide with support, to the developing vasculature. LÄS MER

  4. 13. Indirect effects of river regulation : consequences for landbirds of reduced numbers of aquatic insects

    Författare :Darius Strasevicius; Björn Malmqvist; Tapio Eeva; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boreal region; Simuliidae; Leucocytozoon; pied flycatcher; aquatic insects; breeding success; blood parasites; bird communities; river regulation; impoundment; Biology; Biologi;

    Sammanfattning : Abstrakt: Jag har undersökt hur älvreglering påverkar mängden knott (Tvåvingar: Simuliidae) längs flera norrlandsälvar och vilka konsekvenser denna påverkan får för den landlevande fågelfaunan. Studien visar att utbyggnad av älvar har en negativ effekt på mängden knott. LÄS MER

    Författare :Olof Hellgren; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; Plasmodium; bird-migration; transmission; blackfly; host-specificity; host-preference; cytochrome b; DHFR-TS; recombination; phylogeny; Ecology; Ekologi; Genetics; cytogenetics; Genetik; cytogenetik; Parasitology human and animal ; Haemoproteus; Leucocytozoon; Parasitologi människa och djur ; Animal ecology; Djurekologi; Natural science; Naturvetenskap;

    Sammanfattning : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. LÄS MER

  7. 15. New Aspects of Mast Cell Progenitors in Health and Disease

    Författare :Maya Salomonsson; Jenny Hallgren Martinsson; Silvia Bulfone-Paus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mast cells; Mast cell progenitor; Lung function; Bone marrow; Blood; Activation; Chemotactic receptors;

    Sammanfattning : Mast cells are tissue-resident immune cells that are well known for their involvement in asthma and allergy. They originate in the fetal yolk sac, or in the bone marrow. From the bone marrow, they are released as immature progenitors that are transported via the blood circulation to the peripheral tissue, where they mature. LÄS MER
