  1. 1. Metabolic Studies with Liquid Separation Coupled to Mass Spectrometry

    Författare :Erik Allard; Jonas Berguist; Per Sjöberg; Risto Kostiainen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; liquid chromatography; mass spectrometry; tandem mass spectrometry; method development; capillary electrophoresis; electrospray ionization; time-of-flight; quantitation; metabolomics; metabonomics; pattern recognition; ximelagatran; melagatran; charge state; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Metabolism is the sum of all chemical processes with the purpose to maintain life, as well as enable reproduction, in a living organism. Through the study of metabolism, increased understanding of pharmacological mechanisms and diseases can be achieved. LÄS MER

    Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER

  4. 3. Synthesis and spectroscopic characterization of emerging synthetic cannabinoids and cathinones

    Författare :Andreas Carlsson; Johan Dahlén; Martin Josefsson; Peter Konradsson; Simon Dunne; Mikael Hedeland; Linköpings universitet; []

    Sammanfattning : The application of different analytical techniques is fundamental in forensic drug analysis. In the wake of the occurrence of large numbers of new psychoactive substances possessing similar chemical structures as already known ones, focus has been placed on applied criteria for their univocal identification.

    Sammanfattning : Diabetic kidney disease is a serious complication of diabetes with a complex and incompletely understood pathology. In this work, the molecular changes in diabetic rat kidneys at a very early disease stage were studied using nanospray desorption electrospray ionisation mass spectrometry imaging. LÄS MER

  7. 5. Cerebrum Illuminans : Mass Spectrometric Analysis of Protein and Peptide Dynamics in Neurological Diseases

    Författare :Jörg Hanrieder; Jonas Bergquist; Malin Andersson; Ulf Hellman; Alma Burlingame; Uppsala universitet; []

    Sammanfattning : The human brain (lat. cerebrum) is the most complex and heterogeneous organ in the human body. It is involved in a great number of body functions like movement, touch sensing, vision, hearing, smelling, hormone regulation and many more. In no other organ, the molecular communication mechanisms between different cells are so poorly understood. LÄS MER
