    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acclimatization; Acute Mountain Sickness; Adaptation; Apnea; Breath-hold diving; Cardiovascular diving response; High-altitude; Hypoxia tolerance; Spleen; Acklimatisering; Andhållningsdykning; Anpassning; Apné; Kardiovaskulära dykresponsen; Hög höjd; Hypoxitolerans; Hög-höjdssjukdom; Mjälte; Syrebärande kapacitet;

    Abstract : High-altitude mountaineers - just as freedivers - are exposed to hypoxia. During freediving, the diving response leads to reduced oxygen consumption, and splenic contraction increases circulating hemoglobin concentration (Hb), which enhances freediving performance. READ MORE

  4. 2. Clinical and experimental studies in Philadelphia chromosome negative chronic myeloproliferative disorders

    Author : Peter Johansson; Göteborgs universitet; []
    Keywords : myeloproliferative disorders; polycythaemia vera; essential thrombocythaemia; epidemiology; erythropoietin; red-cell mass; spleen size; thrombo-embolic; PRV-1.;

    Abstract : The present thesis deals with various aspects on the (a) epidemiology, (b) diagnosis, and (c) molecular biology in Philadelphia chromosome negative (Ph-) chronic myeloproliferative disorders (MPD). First, the incidence of the three Ph- MPD, polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) was investigated in the city of Göteborg, Sweden during the years 1983-1999 (Paper I).

  5. 3. Developmental role and ligand binding properties of macrophage scavenger receptor MARCO

    Author : Yunying Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Macrophages express several cell surface receptors, that mediate the recognition of a wide range of endogenous and exogenous ligands. In this manner, macrophages are able to perform their multiple biological functions in regulation of homeostasis and host defense. READ MORE

  6. 4. Purification and biodistribution of extracellular vesicles

    Author : Joel Z Nordin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Extracellular vesicles (EVs) are nano-sized vesicles that contain bioactive lipids, RNAs and proteins, which can be transferred to recipient cells. EVs are important for physiological as well as pathological processes, such as coagulation and immune homeostasis, aiding cancer metastasis and spread of infectious diseases. READ MORE

  7. 5. Chicken domestication : Effects of tameness on brain gene expression and DNA methylation

    Author : Johan Bélteky; Per Jensen; Anna Kukekova; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Domestication greatly increases phenotypic variation in a short time span, with selection for a single phenotype and a plethora of associated phenotypic changes as an outcome of the process. The domestication process influences the underlying genomic architecture of a species, and the success and speed of the process is likely influenced by it. READ MORE
