  1. 1. Genomic selection and genome-wide association studies to dissect quantitative traits in forest trees

    Detta är en avhandling från Umeå : Umeå University

    Författare :Biyue Tan; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Genomic prediction; genome-wide association study; additive effects; dominance effects; epistasis effects; realized relationship matrix; Eucalyptus grandis; Eucalyptus urophylla;

    Sammanfattning : The convergence of quantitative genetics of complex traits with genomic technologies is quickly becoming an innovative approach to explore fundamental genetic questions and also have practical consequences for implementations in tree breeding. In this thesis, I used genomic selection and genome-wide association studies (GWAS) to dissect the genetic basis of quantitative traits, i. LÄS MER

  2. 2. Towards surgical use of matrix metalloproteinase biology

    Detta är en avhandling från Linköping University Electronic Press

    Författare :Björn Pasternak; Linköpings universitet.; Linköpings universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; colon; tetracyclines; tissue inhibitor of metalloproteinases TIMP ; wound healing.; colorectal surgery; extracellular matrix; humans; matrix metalloproteinases MMPs ; rats; surgical anastomosis; sutures; tendon injuries; MEDICINE Surgery Surgical research Orthopaedics; MEDICIN Kirurgi Kirurgisk forskning Ortopedi;

    Sammanfattning : Matrix metalloproteinases (MMPs), such as collagenases, are a family of enzymes capable of degrading most constituents of the extracellular matrix. MMPs are thought to be involved in the aetiopathogenesis of tendon rupture. Additionally, failure of healing has in some instances been associated with elevated levels of MMPs. LÄS MER

  3. 3. Modelling and simulation of plastic deformation on small scales interface conditions and size effects of thin films

    Detta är en avhandling från Stockholm : KTH

    Författare :Per Fredriksson; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strain gradient plasticity; Size effects; Thin films; Interface; Finite element method; Dislocations; Constitutive behaviour; Hardening behaviour; Indentation; Contact mechanics; Metal matrix composites; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Sammanfattning : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. LÄS MER

  4. 4. Extracellular matrix as a regulator of cell behavior : Biological effects of hyaluronan biosynthesis and catabolism

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mehdi Rahmanian; Uppsala universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Hyaluronan; hyaluronidase; CD44; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Extracellular matrix surrounding cells is an important regulator of cellular functions. Hyaluronan (HA) is a glycosaminoglyean and a constituent component of the extracellular matrix in all tissues. It is synthesized by hyaluronan syntheses (HAS) at the inner surface of cell membrane and degraded by hyaluronidases to small fragments. LÄS MER

  5. 5. Lysophosphatidic acid Physiological effects and structure-activity relationships

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ulrika K. Nilsson; Linköpings universitet.; Linköpings universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lysophospholipids pharmacology; physiology; structure-activity relationship; muscle; smooth; drug effects; myometrium; norepinephrine; epinephrine; signal transduction; MEDICINE; MEDICIN;

    Sammanfattning : Lipids havepreviously been considered primarily as building blocks of the cell membrane, but are now also recognized as important cell signaling molecules. Lysophosphatidic acid (LPA) is a glycerophospholipid consisting of a phosphate head group, a linker region, and a lipophilic tail. LÄS MER
