  1. 1. Direct and indirect effects of fish predation and excretion in aquatic food webs

    Detta är en avhandling från Limnologiska avdelningen, Ekologihuset S-223 62 Lund, Sweden

    Författare :José Luiz Attayde; Lunds universitet.; Lund University.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine biology; Hydrobiology; zooplankton; resilience; predation; phytoplankton; nutrient enrichment; nutrient recycling; interaction strength; herbivory; food webs; food chain; excretion; fish; detritus; detritivory; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

    Sammanfattning : The aim of this thesis was to elucidate the mechanisms by which planktivorous fish can affect planktonic communities in lakes and how they may affect benthic communities through their effects on planktonic communities. In a laboratory experiment, nutrients released by fish increased algal biomass and altered phytoplankton community structure, suggesting that fish can affect phytoplankton by directly releasing nutrients.

  2. 2. In vivo Pharmacokinetic Interactions of Finasteride and Identification of Novel Metabolites

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anna Lundahl; Uppsala universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug-drug interactions; herb-drug interactions; pharmacokinetics; metabolism; CYP3A4; hydroxylation; glucuronidation; UGT enzymes; mass spectrometry; biliary excretion; urinary excretion; finasteride; PHARMACY; FARMACI;

    Sammanfattning : The general aim of this thesis was to improve the understanding of the in vivo pharmacokinetics and, in particular, the metabolism of finasteride, a 5α-reductase inhibitor used in the treatment of enlarged prostate glands and male pattern baldness. CYP3A4 has been identified as the major enzyme involved in the sequential metabolism of finasteride to ω-OH finasteride (M1) and ω-COOH finasteride (M3). LÄS MER
