  1. 11. Human Exposure Biomarkers of Some Commonly Used Pesticides

    Författare :Moosa Faniband; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exposure biomarker; Biomonitoring; Pesticides; human experimental exposures; Mass Spectrometry;

    Sammanfattning : The use of pesticides has caused pollution of surface and groundwater, soil and air across the world. Many pesticides cause health effects in humans. General populations are exposed to some degree and diet is reported to be a main source of exposure. LÄS MER

  3. 12. Applications of On-Line Continuous Solvent Extraction in Nuclear Chemistry

    Författare :Rikard Malmbeck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactor water; Seaborgium; BWR; mixer-settlers; Dubnium; Bohrium; transactinides; centrifuges; speciation; SISAK; solvent extraction; Iodine; Rutherfordium;

    Sammanfattning : Methods and procedures for on-line continuous chemical separation of iodine species in reactor water and for transactinides in heavy element chemistry have been developed. Radioiodine is one of the more important fission products in terms of nuclear reactor safety due to its high fission yield, significant radiobiological hazard and potential volatility. LÄS MER

  4. 13. Synthesis of 18F- and 76Br-labelled oligonucleotide and nucleoside derivatives

    Författare :Elisabeth Hedberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : With the aim of developing synthetic routes to oligodeoxynucleotides and analogues labelled with the positron-emitting radionuclides 18F and 76Br (half-lives 1.8 and 16. LÄS MER

  5. 14. Prioritization of phytotoxins according to their threat to water quality

    Författare :Inés Rodríguez Leal; Matthew MacLeod; Ullrika Sahlin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Natural toxins are pollutants of emerging concern. Despite being ubiquitous in the European environment, thus far little action has been taken to conduct screening-level assessment of their presence in drinking water. LÄS MER

  7. 15. Pharmacokinetic aspects of the blood-brain barrier transport and equilibration of opioids studied with microdialysis in rats and mice

    Författare :Rujia Xie; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : The blood-brain barrier (BBB) transport and equilibration of opioids with different physico-chemical properties and similar structures - codeine, morphine, morphine3-glucuronide (M3G) and morphine-6-glucuronide (M6G) - were investigated in rats and mice using microdialysis. The influences of active efflux pumps, P-glycoprotein (Pgp) and multidrug resistance protein (MRP1), on the BBB transport of morphine and M3G were studied. LÄS MER
