  1. 1. Release of coexisting neurotransmitters : in vitro studies on the release of the putative neurotransmitters serotonin, substance P and TRH from rat ventral spinal cord

    Författare :Kerstin Iverfeldt; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  3. 2. Mass spectrometry based analysis of drugs, neurotransmitters and lipids in invertebrate model systems

    Författare :Nhu TN Phan; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CE-MS; Imaging mass spectrometry; Lipids; Neurotransmitters; Drug; Drosophila; C. elegans;

    Sammanfattning : Mass spectrometry (MS) is one of the most universal analytical techniques due to its label-free detection principle and high chemical specificity, high selectivity, and sensitivity. MS is diverse with many different types of systems to meet different analytical demands from various research areas. LÄS MER

  4. 3. Development and Application of Software Tools for Mass Spectrometry Imaging

    Författare :Patrik Källback; Per E. Andrén; Per Svenningsson; Anna Nilsson; Benjamin Bowen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass spectrometry imaging; MALDI; DESI; msIQuant; quantitation; neurotransmitters; drugs; derivatization; brain; compression; data entropy reduction;

    Sammanfattning : Mass spectrometry imaging (MSI) has been extensively used to produce qualitative maps of distributions of proteins, peptides, lipids, neurotransmitters, small molecule pharmaceuticals and their metabolites directly in biological tissue sections. Moreover, during the last 10 years, there has been growing demand to quantify target compounds in tissue sections of various organs. LÄS MER

  5. 4. Chemical circuitry in the visual system of the fruitfly, Drosophila melanogaster

    Författare :Agata Kolodziejczyk; Dick Nässel; Axel Borst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optic lobe; lamina; neurotransmitters; neuropeptides; tangential neurons; Animal physiology; Zoofysiologi; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : Signal processing in the visual system is mediated by classic neurotransmission and neuropeptidergic modulatory pathways. In Dipteran insects, especially in the fruitfly Drosophila melanogaster, the morphology of the visual system is very well described. LÄS MER

  7. 5. PROBING SECRETORY VESICLES AND LIPOSOME MODEL SYSTEMS USING NANOSCALE ELECTROCHEMISTRY AND MASS SPECTROMETRY

    Författare :Jelena Lovric; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuroendocrine cells; NanoSIMS; liposomes; neurotransmitters; large dense core vesicles; Exocytosis; ToF-SIMS; vesicle electrochemical cytometry; electrochemistry; amperometry;

    Sammanfattning : Cellular communication is based on the process of exocytosis, regulated release of chemical messengers into the extracellular space. These messengers, neurotransmitters, are packed into vesicles that during exocytosis fuse with the plasma membrane and release their content. LÄS MER
