  1. 11. Analytical Methods For Sports Drugs: Challenges and Approaches

    Författare :Hatem Elmongy; Magnus Ericsson; Leopold Ilag; Mikael Hedeland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sports Drugs; Doping in Sports; Steroids; LC-MS MS; Chiral analysis; high-resolution mass spectrometry; Sample preparation; Biological samples; solid phase extraction; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Drugs used to enhance human performance in sport competitions are prohibited by the world anti-doping association (WADA). Biological samples from athletes are continuously tested for adverse analytical findings regarding the identity and/or quantity of the banned substances. LÄS MER

  3. 12. Neuroactive steroids and rat CNS

    Författare :Vita Birzniece; Bo Söderpalm; Umeå universitet; []
    Nyckelord :Estradiol; progesterone; HRT; allopregnanolone; UC1011; serotonin receptor; GABAA receptor; mRNA; Morris water maze; silent second; tolerance; Clinical Neurophysiology; klinisk neurofysiologi;

    Sammanfattning : Several studies suggest profound effects on mood and cognition by neuroactive steroids. Estrogen alone or in combination with antidepressant drugs affecting the serotonin system has been used to treat mood disorders. On the other hand, progesterone is related to negative effects on mood and memory. LÄS MER

  4. 13. Acupuncture in reproductive medicine. Applications in human assisted reproduction and aspects of clinical and experimental neuroendocrinology

    Författare :Elisabet Stener-Victorin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electro-acupuncture; blood flow impedance; circulation; uterine artery; in-vitro fertilization; oocyte aspiration; polycystic ovary syndrome; experimentally induced PCO; anovulation; gonadotropins; steroids; neuropeptides; b-endorphin; nerve growth factor; corticotropin-releasing factor.;

    Sammanfattning : The use of acupuncture in the area of reproductive medicine is relatively new, and it has been rather poorly investigated in the past. When muscle afferents are stimulated by acupuncture in somatic segments related to the innervation of the ovaries and the uterus, functional changes occur in the neural substrate that may influence reproductive function and result in peripheral, segmental and central effects.

  7. 15. Membrane protein proteomics - Novel method for membrane protein identification and quantification

    Författare :Maria Bentz; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemisk teknik; mebran; steroider; Lipider; membranes; steroids; Lipids; enzymologi; Proteiner; Membrane proteins; Proteomics; Proteinase K; N-terminal labelling; Relative Quantitation; Database search; Cancer; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; enzymology; Proteins; Biochemical technology;

    Sammanfattning : Membrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. LÄS MER
