  2. 1. Phylogeny of Artiodactyla and Cetacea - based on mitochondrial genomes

    Author : Björn M Ursing; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; mitochondrial genome; phylogeny; Artiodactyla; Cetacea; cytogenetics; Genetik; cytogenetik;

    Abstract : Artiodactyla (eved-toed ungulates) and Cetacea (whales) are two mammalian orders that are commonly recognised as sistergroups. Recently it has been suggested that Cetacea originated within Artiodactyla, but the relationships among the different artiodactyl lineages and Cetacea have not been conclusively established.

  4. 2. Mechanisms of Prodynorphin Gene Dysregulation in the Brain of Human Alcoholics

    Author : Malik Mumtaz Taqi; Georgy Bakalkin; Fred Nyberg; Hallberg Mathias; Wolfgang.H Sommer; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PHARMACY; FARMACI;

    Abstract : The endogenous opioid system (EOS) including dynorphin opioid peptides and κ-opioid receptor (KOR) plays a critical role in alcohol dependence. Aims of the thesis were to evaluate whether the EOS undergoes molecular adaptations in brain areas involved in cognitive control of addiction in human alcohol dependent subjects, and to analyze the impact of genetic and epigenetic factors on these adaptive changes.

  5. 3. Milk Genomics – Impact of Genetic Polymorphism on Bovine Milk Composition and Processability

    Author : Maria Glantz; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; milk genomics; bovine milk; milk composition; technological properties; processability; cheese; quantitative genetic evaluation; single gene effect; genomic selection; genetic polymorphism; leptin; direct genomic value;

    Abstract : Milk genomics is a new area of research that explores the relations between cow genetics and milk characteristics. Identifying the genes controlling compositional and technological traits of milk will give opportunities to select cows for targeted milk production. In this thesis, the impact of different genetic approaches, i.e. READ MORE

  6. 4. Dynorphin A – Interactions with receptors and the membrane bilayer

    Author : Johannes Björnerås; Lena Mäler; Astrid Gräslund; Göran Widmalm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik; Biochemistry; biokemi;

    Abstract : The work presented in this thesis concerns the dynorphin neuropeptides, and dynorphin A (DynA) in particular. DynA belongs to the wider class of typical opioid peptides that, together with the opioid receptors, a four-membered family of GPCR membrane proteins, form the opioid system. READ MORE

  7. 5. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression

    Author : Katharina Bruzelius; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; milk; Natural science; cancer; prolactin; insulin; hydrocortisone; retinoic acid; MAC-T; northern blot; two-dimensional electrophoresis; bovine mammary gland; selenium; selenoprotein;

    Abstract : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. READ MORE
