  1. 1. Protection of Biomolecules by Antioxidants - Mechanisms and Applications

    Författare :Carl Grey; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dG; antioxidants; mass spectrometry; Analytical chemistry; Analytisk kemi; Food and drink technology; Livsmedelsteknik; Bioteknik; Biotechnology; DNA; Oxidation; Protein; Fenton reaction;

    Sammanfattning : Reactive oxygen species (ROS) consisting of various oxygen-based free radicals as well as other reactive non-radical species produced in O2-related metabolism or through other processes are involved in the oxidation of such vital biomolecules as DNA, proteins and lipids. The types of oxidation represented here are known to cause many different diseases and disorders in human beings, such as cancer, Alzheimer's disease and ageing. LÄS MER

  3. 2. Neurotransmission in CNS regions involved in pain modulation : neurochemical effects of analgesic drugs and spinal cord stimulation in the spinal cord and midbrain periaqueductal grey of the rat

    Författare :Carl-Olav Stiller; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adenosine; dorsal horn; GABA; microdialysis; neurotensin; opioids; periaqueductal gray; sciatic nerve lesion; receptor binding; spinal cord stimulation; substance P.;

    Sammanfattning : The dorsal hom of the spinal cord and the midbrain penaqueductal grey matter (PAG) are important regions for pain modulation. In this thesis the effects of opioids and spinal cord stimulation (SCS) on the release of gamma-amino butyric acid (GABA), substance P (SP) and neurotensin (NT) were investigated in these regions of the rat by in vivo microdialysis.

  4. 3. On the evaluation of print mottle

    Författare :Carl-Magnus Fahlcrantz; Jan-Olof Eklundh; Jon Hardeberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mottle; Print quality; Texture; Image analysis; Perception; Computer science; Datalogi;

    Sammanfattning : Print Mottle is perhaps one of the most disturbing factors influencing overall Print Quality. Mottle has traditionally been evaluated by estimating the reflectance variation in the print. LÄS MER
