  1. 21. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology

    Författare :Jothi Kumar Yuvaraj; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; pheromone receptors; olfaction; chemosensory; sensillum; HEK 293 cells;

    Sammanfattning : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).

  3. 22. Gene expression and regeneration in ophiuroids: A study of transcriptional activity and regeneration in the temperate Amphiura filiformis and Antarctic Ophionotus victoriae

    Författare :Gavin Burns; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; echinoderm; regeneration; ophiuroid; gene expression; antarctica;

    Sammanfattning : Regeneration, in which lost or damaged tissues are re-grown, is a common phenomenon amongst animals and especially so within the ophiuroids (brittle stars) of the phylum echinodermata. The process of regeneration begins with the injury event followed by a period of cell and tissue reorganization which results in wound healing and tissue re-growth. LÄS MER

  4. 23. Haemophilia in Sweden – Studies on mutations and clinical implications

    Författare :Annika Mårtensson; Enheten för pediatrisk hematologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; haemophilia; factor VIII; factor IX; factor 8 gene; factor 9 gene; carriers; prenatal diagnosis; mutations; inhibitors; haplotype;

    Sammanfattning : Introduction: Haemophilia A (HA) and B (HB) are two of our most common inherited bleeding disorders and are due to a variety of gene mutations. Aims: The overall objective of the present research was to perform clinical and basic scientific studies on haemophilia in Sweden to further improve and individualise the care of haemophilia patients and their relatives.

  5. 24. Evolution of mate signalling in moths: Biosynthetic gene families and diversification of female sex pheromones

    Författare :Marjorie Liénard; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; duplication; transcriptome; fatty-acyl-CoA reductase; fatty-acyl-CoA desaturase; fatty-acid biosynthesis; odour; insect; Lepidoptera; phylogeny; qPCR; heterologous expression; mutagenesis;

    Sammanfattning : Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. LÄS MER

  7. 25. Genomics and bioinformatics approaches to functional gene annotation

    Författare :Danielle Kemmer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Biomedical research has been undergoing a quasi-revolution with the dawn of the genomics era. The flood of sequence data from the various genome projects, the task of cataloging the entire coding portion of a genome instead of identifying and characterizing individual genes, as well as technical demands accompanying these developments have posed great challenges to the research community.
