  1. 1. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Staffan Dryselius; Uppsala universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. LÄS MER

    Sammanfattning : Glucose stimulation of insulin release is mediated by depolarisation of the pancreatic β-cells with accompanying entry of Ca2+ through voltage-dependent channels. An important feature of the glucose-induced depolarisation is its rhythmicity causing oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), which trigger pulsatile release of insulin.

    Sammanfattning : Popular Abstract in Swedish Basala ganglierna ligger under hjärnbarken i hjärnan och består av grupper av nervceller som är förbundna med varandra och med hjärnbarken. Till dessa grupper av nervceller hör striatum, globus pallidus, subthalamicus-kärnan och substantia nigra. LÄS MER
