  2. 11. Novel functions of cardiovascular P2 receptors

    Author : Anna-Karin Wihlborg; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Kardiovaskulära systemet; mRNA; EDHF; UTP; UDP; ADP; ATP; P2 receptor; contraction; dilatation; endothelial cells; Heart; VSMC;

    Abstract : The aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes.

  4. 12. Studies on molecular mechanisms in calcium signaling and cellular energy consumption

    Author : Kalaiselvan Krishnan; Hjalmar Brismar; Anders Tengholm; KTH; []
    Keywords : ca2 signaling; ATP; PercevalHR; NKA; diabetes; Angiotensin; Biological Physics; Biologisk fysik;

    Abstract : Ion signaling plays fundamental role in cell survival. Na+ and Ca2+ are critical players in ion signaling. Cells spend the major amount of energy to maintain and regulate Na+ and Ca2+ gradients across the cell membrane. Any disruption in cellular energy consumption by plasma membrane ATPases affects ion signaling and vice versa. READ MORE

  5. 13. Astrocytic communication and cell death during metabolic depression and oxidative stress

    Author : Christina Nodin; Göteborgs universitet; []
    Keywords : astrocyte; gap junction; ATP; ROS; oxidative stress; Annexin V; AIF; programmed cell death; Nrf2; scavenger; iodoacetate; SIN-1;

    Abstract : Stroke is a major cause of death and adult disability in the western world. Most often, stroke is caused by the occlusion of a brain artery. Within the perfusion territory of the occluded vessel, various degrees of necrotic and delayed programmed cell death will occur if the occlusion persists, leading to expanding tissue damage.

  6. 14. Energy metabolic failure within the arterial wall in atherosclerosis

    Author : Max Levin; Göteborgs universitet; []
    Keywords : atherosclerosis; hypoxia; hypoxia marker; bioluminescence imaging; ATP; glucose; lactate; energy metabolism;

    Abstract : Atherosclerosis is a disease that affects large and medium sized arteries. The majority of deaths in a Western population can be directly attributed to complications of this disease. Although research efforts have been vast, the pathophysiological mechanisms underlying atherosclerosis are not fully understood. READ MORE

  7. 15. Gonad and ejaculate allocation in alternative reproductive tactics of salmon and trout with reference to sperm competition

    Author : Tomislav Vladić; Michael Taborsky; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alternative reproductive tactics; sperm competition; brown trout; Atlantic salmon; ATP; ejaculate expenditure; motility; sperm morphology; trade-off; loaded raffle; zoologi; Zoology;

    Abstract : Atlantic salmon, Salmo salar L., and brown trout, Salmo trutta L., exhibit alternative male maturation phenotypes, anadromous and precociously mature parr, which commonly endure in sperm competition at the spawning grounds. READ MORE
