  4. 3. Molecular mechanisms of metal toxicity in neuronal cells

    Författare :Annamaria Rossi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Modification of signal transduction by toxic agents can affect cell metabolism and physiological activity, impair cell capacity to adequately respond to hormones and growth stimuli and consequently compromise cell survival. This thesis describes studies on the interactions between toxic metals, at concentrations comparable to environmental exposure, and Ca2+ signalling in neuronal cells. LÄS MER

  5. 4. SODIUM/IODIDE SYMPORTER-NIS Abundant and Important in Gastric Mucosa

    Författare :Malin Josefsson; Neurogastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ussing chamber; MNNG; gastric iodide secretion; ouabain; gastric cancer; sodium perchlorate; gastric NIS; bile duct cancer; Sodium iodide symporter;

    Sammanfattning : ABSTRACT Background: Iodine is essential for development and growth as a constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. LÄS MER

  7. 5. Effects of Rho kinase, prostacyclin and L-arginine on microvascular permeability and perfusion

    Författare :Cornelia Lundblad; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; skeletal muscle; Rho kinase; prostacyclin; permeability; NO; experimental brain trauma; brain edema; brain contusion; microcirculation; cerebral perfusion;

    Sammanfattning : This thesis presents some effects of Rho kinase, prostacyclin (PGI2) and nitric oxide (NO) in relation to trauma and inflammation by evaluating their effects on microvascular perfusion and permeability in mouse brain and in cat skeletal muscle. PGI2 and NO are endogenous vasoactive substances produced by the endothelium. LÄS MER
