    Sammanfattning : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. LÄS MER

    Författare :Bo-Guang Fan; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; TPN; Parotid glands; Lysosomal enzyme; Insulin; Hypotrophy; Hyperlipidemia; Food passage; Endocrine pancreas; Cholecystokinin; Exocrine pancreas; traumatology; Kirurgi; ortopedi; traumatologi; Gastro-enterology; Gastroenterologi;

    Sammanfattning : During total parenteral nutrition (TPN) adequate nutrition is provided intravenously and the enteral route is bypassed. The integrity of the gastrointestinal (GI) tract, however, is dependent on the passage of food through it. This thesis deals with the effects of TPN on the pancreas and the parotid glands. LÄS MER

  5. 4. Bacterial cytochromes P450-Studies on Cytochrome P450 102A2 and P450 102A3 of Bacillus subtilis

    Författare :Mattias Gustafsson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; AbrB; Spo0A; monooxygenase; heme; Bacillus subtilis; Cytochrome P450; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Cytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. LÄS MER
