  1. 16. 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

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

    Abstract : 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.

  2. 17. Photopatternable Electrolytes for Conducting Polymer Actuators

    Author : Yong Zhong; Edwin Jager; Anthony Turner; Jose Gabriel Martinez; Aleksandar Matic; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electroactive polymers (EAPs) are materials that can change their dimensions or shape in response to electric stimulation. They have attracted considerable interests for their applications as soft, lightweight and silently operating polymer actuators. One significant group of EAPs is conducting polymers. READ MORE

  3. 18. Mammalian cell cycle regulation : characterisation of three genes expressed in proliferating cells

    Author : Maria Starborg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Cell cycle; DNA replication; licensing factor; mitosis; ceheckpoint regulator; centromere regions; cell proliferation marker; nucleolar protein; spermatogenesis;

    Abstract : Proliferating cells undergo different phases in their life cycle. During interphase the cells grow and duplicate their DNA content, followed by a cell division phase, mitosis, which results in two daughter cells. READ MORE

  4. 19. The hippocampal opioid system : role in spatial learning

    Author : Johan Sandin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : opioid; dynorphin; nociceptin; hippocampus; learning; memory; acetylcholine; HPLC; microinjections;

    Abstract : The main aim of the present thesis was to study the role of the endogenous hippocampal opioid system, and in particular, the role of dynorphin B and nociceptin, in spatial learning. The effects of bilateral infusion (using chronic cannulae) of dynorphin B into the dorsal hippocampus (CA3-region), an area containing a high number of dynorphin-containing neurons, were examined in the Morris swim-maze, a spatial task dependent on hippocampal functioning.
