  1. 1. Development and three-dimensional histology of vertebrate dermal fin spines

    Författare :Anna Jerve; Per Erik Ahlberg; Martin Brazeau; Tatjana Haitina; Philippe Janvier; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fin spine; paleontology; early vertebrate; histology; development; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : Jawed vertebrates (gnathostomes) consist of two clades with living representatives, the chondricthyans (cartilaginous fish including sharks, rays, and chimaeras) and the osteichthyans (bony fish and tetrapods), and two fossil groups, the "placoderms" and "acanthodians". These extinct forms were thought to be monophyletic, but are now considered to be paraphyletic partly due to the discovery of early chondrichthyans and osteichthyans with characters that had been previously used to define them.

  3. 2. Musculoskeletal Development in Jawed Vertebrates : Gene function, cis-regulation, and 3D phenotypes in zebrafish

    Författare :Jake Leyhr; Tatjana Haitina; Sophie Sanchez; Per Ahlberg; Chrissy Hammond; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nkx3.2; Gdf5; Mkx; zebrafish; jaw joint; skeleton; fin development; cartilage; tendon; ligament; enhancer; CRISPR Cas9; mutant; microCT; synchrotron; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : Vertebrate skeletons are an intricate framework of bony and cartilaginous structures that form through carefully orchestrated developmental processes, guided by interacting genetic pathways that regulate cellular differentiation, migration, and tissue morphogenesis. The specific timing and localisation of gene expression shapes the diverse array of skeletal elements, from the flexible cartilages of the embryonic stage to the hardened bones that provide structural support in adulthood, and the joints and connective tissues that articulate the musculoskeletal system.

  4. 3. The role of Nkx3.2 and Gdf5 during zebrafish skeletal development

    Författare :Laura Waldmann; Tatjana Haitina; Abigail Tucker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nkx3.2; Gdf5; zebrafish; jaw joint; joints; axial skeleton; appendicular skeleton; fin; enhancer conservation; CRISPR Cas9; OPT;

    Sammanfattning : The vertebrate skeleton is composed of bony and cartilaginous structures that are developed under the control of numerous genetic networks. The transcription factor Nkx3. LÄS MER

  5. 4. Yhdessä ikäihmisen hyväksi

    Författare :Viivi Tikkanen; Mälardalens universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The purpose of this study was to introduce views of the staff working for the Emergency Medical Service (EMS), home care and emergency social services of Kanta-Häme region on non-medical problems of the elderly and responding to them. Another purpose was to present developing methods of multi-professional cooperation. LÄS MER

  7. 5. Glycosaminoglycan Biosynthesis in Zebrafish

    Författare :Beata Filipek-Górniok; Lena Kjellén; Johan Ledin; Kay Grobe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparan sulfate; chondroitin dermatan sulfate; biosynthesis; development; N-deacetylase N-sulfotransferase; glycosyltransferases; morpholino; CRISPR-Cas9;

    Sammanfattning : Proteoglycans (PGs) are composed of highly sulfated glycosaminoglycans chains (GAGs) attached to specific core proteins. They are present in extracellular matrices, on the cell surface and in storage granules of hematopoietic cells. LÄS MER
