  1. 6. Genome-wide association studies on body weight and component traits in an intercross of two divergently selected chicken lines

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Yiwen Chen; [2021]
    Keywords : Genome-wide association study; Advanced Intercross Lines; Virginia chicken lines; artificial selection;

    Abstract : Here we present the genome-wide association study of body weight at 8 weeks of age based onthe advanced intercross pedigree of two chicken lines gone through bi-directional selection.With improved marker density (~3M SNPs) and larger sample size (2667 individuals from F2-F15), 34 loci with suggestive significance are detected, of which 18 loci are novel, and the rest17 loci are consistent with the results of previous quantitative trait locus mapping studies onthis trait with smaller number of genetic markers and fewer individuals.

  3. 7. The Developmental Neurotoxicity of Paracetamol – Evaluation of markers involved in brain development in mice

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Armine Yakub; [2020]
    Keywords : paracetamol; Neurotoxicity; mice;

    Abstract : Paracetamol is a widely used non-prescription analgesic and antipyretic. Despite its wide usage, the mechanism of action of paracetamol is not fully known. READ MORE

  4. 8. Mobility, habitat selection and population connectivity of Lycaena helle in central Sweden : implications for conservation

    University essay from SLU/Dept. of Ecology

    Author : Hanna Modin; [2018]
    Keywords : Lycaena helle; violet copper; Lepidoptera; Lycaenidae; mobility; dispersal; resource selection function; habitat selection; connectivity; metapopulation; stepping stone;

    Abstract : Lycaena helle is an endangered butterfly that is mainly threatened by habitat degradation and fragmentation. For all species with a fragmented distribution, knowledge about mobility, habitat requirements and connectivity is key to developing successful conservation strategies. READ MORE

  5. 9. Pride and prejudice : extra-group paternity in lions and the effects of marker density on kinship and relatedness estimates

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Julia Jansson; [2017]
    Keywords : lion; mating structure; extra-group paternity; Single Nucleotide Polymorphism SNP ; marker density; panthera leo;

    Abstract : The development effective high-throughput sequencing techniques has allowed further insight to the mating systems of wild animal populations and challenged our perception that reproductive behaviour can be predicted from social structure. A recent study of lions (Panthera leo) in Etosha National Park, Namibia, found evidence of extra-group paternity (EGP) which has never before been confirmed among lions. READ MORE

  6. 10. Quality Assurance of the Spatial Accuracy of Large Field of View Magnetic Resonance Imaging

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Fredrik Illerstam; [2014]
    Keywords : MRI; MR; spatial accuracy; spatial distortions; large FOV; MR-only; radiotherapy treatment planning; RTP; gradient non-linearity; B0 inhomogeneity;

    Abstract : In todays Radiotherapy Treatment Planning, RTP, it is common to use Computed Tomography, CT, together with Magnetic Resonance Imaging, MRI, where CT provides electron density information and a geometrical reference, and where MRI provides superior soft tissue contrast. To sim- plify the workflow and improve treatment accuracy, research groups have demonstrated how to exclude CT and use a MRI-only approach. READ MORE
