  1. 1. Development of novel fluorine-18 labeled PET radioligands for monoamine oxidase B (MAO-B)

    Författare :Sangram Nag; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Monoamine oxidases (MAO-A and MAO-B) are important enzymes regulating the levels of monoaminergic neurotransmitters. Selective and irreversible MAO-B inhibitors such as L-deprenyl and rasagiline are clinically used for the treatment of psychiatric and neurological disorders. LÄS MER

    Författare :Saad Elzanaty; Malmö (Abrahamsson) Urologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; zinc; visco-elasticity; sperm motility; SDR5A2; PSA; persistent organohalogen pollutants; NAG; fructose; Epididymis; CASA; acessory sex gland; abstinence period;

    Sammanfattning : Infertility, defined as the inability to conceive after one year of unprotected regular intercourse, affects up to 15% of all couples of reproductive age. The infertility can originate from female, male or both partners. In up to 50% of the affected couples, a male factor is the cause of infertility. LÄS MER

  4. 3. Rethinking the Gospel of Truth : A Study of its Eastern Valentinian Setting

    Författare :Jörgen Magnusson; Gabriella Gustafsson; Anders Hultgård; Birger Pearson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Gospel of Truth; Nag Hammadi; Valentinianism; Gnostic; Gnosticism; early Christianity; Coptic; history of religions; text linguistics; late Antiquity; History of religion; Religionshistoria;

    Sammanfattning : Already in the second century, the Church Father Irenaeus warned against reading the Gospel of Truth that was used among the so-called Valentinians. For more than one and a half millennium GospTruth was lost until in the 1950s a Coptic text was discovered that could be a translation of that work both loved and hated. LÄS MER

  5. 4. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

    Författare :Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

    Sammanfattning : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. LÄS MER

  7. 5. Geochemical and Mineralogical Characterization of Waste Rocks for Preliminary Mine Drainage Quality Prediction

    Författare :Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Berndt Lottermoser; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mine waste characterisation; mine drainage water; ARD; NRD; aqua regia extraction; ABA test; NAG test; SEM mineralogy; sulfide minerals; risk assessment; Applied Geochemistry; Tillämpad geokemi;

    Sammanfattning : Acid or neutral rock drainage (ARD or NRD) with its attendant elevated concentrations of harmful elements presents one of the main challenges related to the management of waste rocks. Low-quality drainage is a particular issue with respect to mineral deposits containing sulfide minerals, of which pyrite and pyrrhotite are especially prone to produce acidic drainage when exposed to oxygen and water.
