  1. 1. Calcium and Phospholipases in Orexin Receptor Signaling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa Johansson; Uppsala universitet.; [2008]
    Keywords : Physiology; orexin; receptor; calcium; phospholipase; cell signaling; GPCR; Fysiologi;

    Abstract : The neuropeptides orexin-A and -B act as endogenous ligands for G-protein-coupled receptors (GPCRs) called OX1 and OX2 receptors. Previous observations have established that orexin receptors have an ability to couple to different G-proteins and signaling pathways and induce Ca2+ elevations via both receptor-operated Ca2+ channels (ROCs) and store-operated Ca2+ channels (SOCs).

  2. 2. Calcium calmodulin-dependent protein kinase signal transduction in cerebral arteries

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Roya Waldsee; Lunds universitet.; Lund University.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CAMK; Ednothelin receptors; Calcium; gene regulation;

    Abstract : Popular Abstract in Swedish Hjärnan är ett organ som utgör 2 % av kroppsvikten men som mottar ca 20 % av hjärtats minut volym och har en mycket hög energi konsumtion. I samband med en blodpropp i något av hjärnas blodkärl eller att ett av hjärnans kärl brister får man en stroke eller cerebral ischemi. READ MORE

  3. 3. Ischemic Cell Death in the CNS - applications of a new in vitro model

    University dissertation from Tobias Cronberg, Lab for Experimental Brain Research, Wallenberg Neuroscience Center, BMC A13, 221 84 Lund

    Author : Tobias Cronberg; Lunds universitet.; Lund University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; Neurology; astrocyte; stroke; adenosine; hyperglycaemia; glucose; free radicals; calcium; in vitro; brain ischemia; slice; neuropsychology; neurofysiologi; neurophysiology;

    Abstract : Popular Abstract in Swedish När blodförsörjningen till hjärnan upphävs uppstår ett tillstånd av blodbrist, ischemi. När hela hjärnan drabbas, som vid ett hjärtstillestånd, kallas detta global ischemi medan fokal ischemi betecknar att blodflödet är upphävt i en del av hjärnan, som vid stroke. READ MORE

  4. 4. Calcium regulation and functions of basic Helix-Loop-Helix transcription factors

    University dissertation from Umeå : Molekylärbiologi

    Author : Juha Saarikettu; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The members of the ubiquitously expressed E-protein subfamily of basic Helix-Loop-Helix (bHLH) transcription factors, E12/E47, SEF2-1 and HEB, have important roles as regulators of gene expression in various differentiation processes, including lymphocyte development and myogenesis. In myogenesis, E-proteins are proposed to function as obligate heterodimer partners for members of the MyoD family of muscle-specific bHLH transcription factors. READ MORE

  5. 5. The involvement of calcium and membrane fusion events in neutrophil secretion and respiratory burst

    University dissertation from Göteborg

    Author : Daniel Granfeldt; Göteborgs universitet.; Gothenburg University.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; calcium; regulated secretion; membrane fusion; SOC; arachidonic acid; intracellular fusion; oxygen free radicals; phagocytosis;

    Abstract : Neutrophil granulocytes play an important role in host defence during the early stages of microbial infection. The neutrophils have to leave the blood stream and migrate out into the tissue where they are able to phagocytose and kill microbes as well as dispose of cell debris from damaged tissues. READ MORE
