  1. 21. Regeneration in the adult brain after focal cerebral ischemia : exploration of neurogenesis and angiogenesis

    Författare :Wei Jiang; Jukka Jolkkonen; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; neurogenesis; angiogenesis; rats; mice; gliosis; BrdU; CBF; protein synthesis; ATP; penumbra; reperfusion; VEGF; 3-D confocal; photothrombosis; MCAO; Medicine; Medicin;

    Sammanfattning : Background: Ischemic stroke ranks as the third major cause of clinical mortality and the leading cause of handicap in adults. Each year, stroke occurs in about 30,000 Swedes. The severity of an acute ischemic stroke depends mainly on the degree and duration of local cerebral blood flow (lCBF) reduction. LÄS MER

  3. 22. The Role of Proline Catabolism in Candida albicans Pathogenesis

    Författare :Fitz Gerald S. Silao; Per O. Ljungdahl; Joachim Morschhäuser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Candida albicans; proline metabolism; ATP; P5C; virulence; macrophage; hyphae; filamentation; Ras1 cAMP PKA; mitochondria; Proline dehydrogenase; P5C dehydrogenase; reactive oxygen species; Proline-P5C cycle; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Candida albicans is an opportunistic fungal pathogen that has evolved in close association with human hosts. Pathogenicity is linked to an array of virulence characteristics expressed in response to environmental cues and that reflect the requirement to take up and metabolize nutrients available in the host.

  4. 23. Lipid Signalling Dynamics in Insulin-secreting β-cells

    Författare :Anne Wuttke; Anders Tengholm; Erik Gylfe; Louis Philipson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP; β-cell; diacylglycerol; insulin secretion; oscillations; PtdIns 4 P; PtdIns 4; 5 P2; protein kinase C; P2Y receptor; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Certain membrane lipids are involved in intracellular signalling processes, among them phosphoinositides and diacylglycerol (DAG). They mediate a variety of functions, including the effects of nutrients and neurohormonal stimuli on insulin secretion from pancreatic β-cells. LÄS MER

  5. 24. Studies of cAMP and Ca2+ signaling in pancreatic islet cells

    Författare :Hongyan Shuai; Anders Tengholm; Erik Gylfe; Sebastian Barg; Albert Salehi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic islet; insulin; glucagon; somatostatin; pancreatic polypeptide; exendin- 9-39 ; GLP-1; GIP; ATP; adenosine; cAMP; Ca2 ; β-cell; α-cell; δ-cell; PP-cell;

    Sammanfattning : The blood glucose-lowering and -elevating hormones insulin and glucagon are released from the pancreatic islet β- and α-cells, respectively. The intracellular messengers Ca2+ and cAMP have central roles in controlling the secretion of both hormones, but the underlying mechanisms are incompletely understood. LÄS MER

  7. 25. Energy Metabolic Stress Syndrome : Impact of Physical Activity of Different Intensity and Duration

    Författare :Stefan Branth; Leif Hambraeus; Gunnar Ronquist; Mats Stridsberg; Lennart Kaijser; Uppsala universitet; []
    Nyckelord :Medicine; energy; ATP; metabolism; nutrition; body-composition; physical-activity; stress; insulin-resistance; ion-pumps; intracellular swelling and -shrinkage; taurine; reactive oxygen species; Medicin;

    Sammanfattning : All living cell functions require an ongoing supply of energy derived from carbohydrates, lipids and proteins with their own pathways of breakdown. All of them end up in the oxidation of reduced coenzymes, yielding chemically-bound energy in the form of adenosine triphosphate (ATP). LÄS MER
