  1. 11. Crystallographic studies of enzymes involved in biosynthesis of fatty acids : beta-ketoacyl-acyl carrier protein synthase II and delta9-stearoyl-ACP desaturase

    Författare :Martin Moche; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In the biosynthesis of fatty acids, the beta-Ketoacyl Acyl Carrier Protein Synthases (Kas) catalyse chain elongation by the addition of two-carbon units derived from malonyl-ACP, to an acyl group bound to CoA or the small protein ACP. These enzymes are potential targets for antibiotics against bacterial or parasitical infections and their mammalian counterparts could hopefully be used as drug targets against certain cancers and obesity.

  3. 12. Pheromones, genes & transcriptomes. A molecular analysis of moth sex pheromone production

    Författare :Maria Strandh; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Female moths emit sex pheromones to lure a mate. In this thesis I examined the transcriptomes of female moth pheromone glands in order to identify genes encoding proteins involved in pheromone production. Two cDNA-libraries were constructed from Agrotis segetum (Noctuidae) pheromone glands and the remaining body tissue, respectively. LÄS MER

  4. 13. Sex pheromone biosynthesis in moth pests : From gene discovery to biotechnological production

    Författare :Marie Dam; Feromongruppen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lepidoptera; Moths; Sex pheromones; Biosynthesis; Desaturases; Gene characterisation; Transcriptomics; Heterologous expression; Biotechnology; integrated pest management;

    Sammanfattning : Moths (Lepidoptera) are some of the most economically important pests in human agriculture. Conventional insecticides used for management promote insecticide resistance in addition to cause human- and environmental harm. This emphasises an inescapable need for sustainable alternatives and integrated practices. LÄS MER

  5. 14. Metabolic consequences of a Paleolithic diet in obese postmenopausal women

    Författare :Caroline Blomquist; Tommy Olsson; Elin Chorell; Per-Arne Svensson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postmenopausal women; Paleolithic diet; randomized diet intervention; fat metabolism; low-grade inflammation; circulating fatty acids; diet validation; obesity; insulin resistance; Postmenopausala kvinnor; Paleolitisk kost; randomiserad kostintervention; fettmetabolism; fetma; låggradig inflammation; cirkulerande fettsyror; kostvalidering; fetma; insulin resistens; medicin; Medicine;

    Sammanfattning : BackgroundObesity, in particular abdominal adiposity, is associated with elevated fatty acids and pro-inflammatory adipokines, which are linked to ectopic fat storage and insulin resistance. During menopause, there is a redistribution of fat from the peripheral to abdominal depots. LÄS MER

  7. 15. Candidate gene effects on beef quality

    Författare :Marie Ekerljung; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The contribution of five candidate genes to the variation in meat tenderness, pH, colour, marbling and water holding capacity (WHC) was analysed in muscle samples from 243 young bulls of Angus, Charolais, Hereford, Limousin, or Simmental breed, raised in Swedish commercial herds. The animals were genotyped for single nucleotide polymorphisms (SNPs) in the genes encoding calpain 1 (CAPN1:c. LÄS MER
