4. 8. Electrophysiology of pancreatic A-, B- and D-cells studied in intact mouse islets of Langerhans

   Författare :Sven Göpel; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; somatostatin; glucagon; insulin; patch-clamp; membrane potential; Pancreatic islet; ion channel; diabetes; Physiology; Fysiologi;

   Sammanfattning : Abstract The electrophysiological properties of insulin-secreting b-cells, glucagon-releasing a-cells and somatostation-producing d-cells in intact mouse pancreatic islets were investigated using the perforated patch whole-cell technique. It is demonstrated that it is possible to functionally identify the different cell types in situ. LÄS MER

7. 10. Sångaren på den tomma spelplatsen - en poetik. Att gestalta Gilgamesheposet och sånger av John Dowland och Evert Taube

   Författare :Sven Kristersson; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Orpheus; empty space; performance; song; verse; Evert Taube; Gilgamesh; John Dowland;

   Sammanfattning : The aim of this doctoral project is to explore an expanded role of the singer in an artistic field situated between poetry, theatre, music and reflection. The project consists of three parts: Firstly, three performances of songs and poetry: (a) Me, Me and None but Me!, a blank-verse monologue connecting songs of John Dowland, (b) Gilgamesh – The Man Who Refused to Die, a musical version of the Babylonian Gilgamesh Epic, and (c) The Poet and Time, interpretations of works by the Swedish chansonier Evert Taube.
