  1. 11. Organelle movement in melanophores: Effects of Panax ginseng, ginsenosides and quercetin

    Författare :Therese Eriksson; Rolf Andersson; Samuel Svensson; Ingemar Lundström; Robert Kronstrand; Per Hammarström; Linköpings universitet; []
    Nyckelord :melanophores; Panax ginseng; ginsenosides; quercetin; organell anterograde transport; endothelin-3; mitogen activated protein kinase; protein kinase C; MEDICINE; MEDICIN;

    Sammanfattning : Panax ginseng is a traditional herb that has been used for over 2000 years to promote health and longevity. Active components of ginseng include ginsenosides, polysaccharides, flavonoids, polyacetylenes, peptides, vitamins, phenols and enzymes, of which the ginsenosides are considered to be the major bioactive constituents.

  3. 12. Host control of intracellular bacterial infections

    Författare :Emma Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Listeria monocytogenes; CD44; flagellin; Chlamydia pneumoniae; TLR; NOD; IFNalpha beta; IFN-gamma;

    Sammanfattning : In this thesis various immune mechanisms regulating control of infections with the intracellular bacteria Listeria monocytogenes and Chlamydia pneumoniae have been studied. These bacteria infect macrophages in which they can successfully grow. However, macrophages are potent killers of intracellular bacteria. LÄS MER

  4. 13. Molecular mechanisms of VEGF-mediated angiogenesis and vascular permeability

    Författare :Anna Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Angiogenesis; VEGF; vascular permeability;

    Sammanfattning : Angiogenesis, sprouting of new capillaries from pre-existing blood vessels, is a tightly regulated multi-step process. One of the key mediators in this process is the Vascular Endothelial Growth Factor (VEGF). Many tumors express high levels of VEGF and pathological angiogenesis is considered a hallmark of malignant tumor growth. LÄS MER

  5. 14. Child Maltreatment in Bangladesh : Perceptions, Prevalence and Determinants

    Författare :Md. Atiqul Haque; Ulla-Britt Eriksson; Sven Arne Silfverdal; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child Maltreatment; ICAST-C; Public Health; Bangladesh; Public Health Science; Folkhälsovetenskap;

    Sammanfattning : Background: Like most low- and middle-income countries Bangladesh have no prevalence data on Child Maltreatment (CM) and lack a reporting system.Objectives: The overall aims of the thesis were to generate knowledge on CM in the Bangladeshi society and to estimate the prevalence and associated risk factors.

  7. 15. Spark Plasma Sintering Enhancing Grain Sliding, Deformation and Grain Size Control : Studies of the Systems Ti, Ti/TiB2, Na0.5 K0.5 NbO3, and Hydroxyapatite

    Författare :Mirva Eriksson; Zhijian Shen; Takashi Goto; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spark plasma sintering; plastic deformation; grain growth; titanium; TiB2; hydroxyapatite; Na0.5K0.5NbO3; ferroelectric; transparent; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

    Sammanfattning : The unique features of the Spark plasma sintering (SPS) were used to investigate the sintering and deformation behaviour of titanium and titanium–titanium diboride composites, and to control the sintering and grain growth of ferroelectric Na0.5K0.5NbO3 (NKN) and of hydroxyapatite (HAp).
