  1. 21. Ovarian hormones and effects in the brain : studies of neurosteroid sensitivity, serotonin transporter and serotonin2A receptor binding in reproductive and postmenopausal women

    Author : Anna-Carin Wihlbäck; Tord Naessén; Umeå universitet; []
    Keywords : estradiol; progesterone; progestin; neurosteroids; saccadic eye velocity; sedation; hormone replacement therapy HRT ; menopause; menstrual cycle; mood; serotonin; paroxetine; lysergic acid diethylamide; platelets; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Background: Estrogen has been reported to enhance well-being and quality of life during the climacteric phase. In women with an intact uterus estrogen treatment is always combined with progestins in order to protect the endometrium from hyperplasia and malignancies. READ MORE

  2. 22. Development of in vitro and ex vivo positron-emitting tracer techniques and their application to neurotrauma

    Author : Sven Sihver; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Short-lived radionuclides; in vitro receptor binding; in vitro and ex vivo autoradiography; positron emission tomography; benzodiazepine; muscarinic acetylcholine; and NMDA receptors in CNS; experimental neurotrauma; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : The use of positron-emitting tracers has been extended beyond tomographic facilities in the last few years, giving rise to a general positron-emitting tracing technique. The methodological part of the present thesis involved the evaluation of the performance of storage phosphor (SP) plates, with tracers labeled with high-energy, short-lived, positron-emitting radionuclides, using homogenized tissue specimens and autoradiography with frozen brain sections.

  3. 23. Ion channels in drug discovery : focus on biological assays

    Author : Kim Dekermendjian; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ion channels; GABAA receptor; sodium channels; TRPM8; drug discovery; high throughput screening assays; FLIPR; automated electrophysiology;

    Abstract : Ion channels are well characterised drug targets. However, the techniques used to study ion channel pharmacology have not been particularly applicable to modern drug discovery. READ MORE

  4. 24. Sex and stress steroid modulation of GABA mediated chloride ion flux in rat CNS

    Author : Jessica Strömberg; Per Lundgren; Torbjörn Bäckström; David Haage; Esa Korpi; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; allopregnanolone; chloride ion uptake; patch-clamp; 3beta-steroids; kinetic parameters; rat brain; Obstetrics and gynaecology; Obstetrik och gynekologi;

    Abstract : Background: Sex and stress steroids are metabolized to 3a-hydroxy-pregnane-steroid metabolites such as allopregnanolone (Allo) and tetrahydrodeoxycorticosterone (THDOC). Allo and THDOC are neuroactive steroids that are metabolized in the brain and act in brain as potent positive GABAA receptor function modulators. READ MORE

  5. 25. Cellular mechanisms of anaesthetic agents

    Author : Karin Björnström Karlsson; Bertil Fredholm; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Anaesthesia is given to approximate 5% of the Swedish population annually, with the great advantage of painless surgery, but it also has side effects such as depression of blood pressure that might give a heart infarction. Exactly how anaesthetic agents cause anaesthesia is poorly known. READ MORE
