    Författare :Hilmar Vidarsson; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : Aim: In this study we focused on the biological importance of the forkhead transcription factor Foxi1. The overall aim was to elucidate the functional role of Foxi1 in the inner ear, kidney and epididymis. LÄS MER

  4. 3. Carbothermal synthesis of nano-structured metal, carbides and nitrides, using solution processed precursors; from precursor to product

    Författare :Sarmad Naim Katea; Gunnar Westin; Hilmar Vidarsson; Sanjay Mathur; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solution-based chemical processing; sol-gel; ceramic powders; transition metal carbides and nitrides; sintering; nickel binder; mechanical properties; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : This thesis describes how solution chemical based carbothermal syntheses can be used for the synthesis of nanostructured zirconium carbide and nitride nanophase powders as well as a nickel-metal coating on NbC for use as a sintering agent. The focus is on the development of novel synthesis routes using atomic or small nanoscale level mixing of the metal oxide and carbon source in the starting precursors, enabling the use of lower synthesis temperatures and non-agglomerated nanosized powders.

  5. 4. Transcriptional profiling of human embryonic stem cells and their functional derivatives

    Författare :Jane Synnergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcription; differentiation; human embryonic stem cells; gene expression; Naturvetenskap;

    Sammanfattning : Human embryonic stem cells (hESCs) represent populations of pluripotent, undifferentiated cells with unlimited replication capacity, and with the ability to differentiate into any functional cell type in the human body. Based on these properties, hESCs and their derivatives provide unique model systems for basic research on embryonic development. LÄS MER
