  1. 11. The Role of Lhx2 During Organogenesis : - Analysis of the Hepatic, Hematopoietic and Olfactory Systems

    Författare :Åsa Kolterud; Leif Carlsson; Stefan Thor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; LIM-homeobox gene; Lhx2; fetal liver; hepatic stellate cells; hematopoietic stem cells; septum transversum; self-renewal; odorant receptor genes; olfactory epithelium; olfactory sensory neuron; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : During embryonic development a variety of tissues and organs such as the lung, eye, and kidney are being formed. The generation of functional organs is regulated by reciprocal cell-cell interactions. Via the secretion of soluble molecules one type of cells affect the fate of their neighboring cells. LÄS MER

  3. 12. Specification of the lens and olfactory placodes and dorsoventral patterning of the telencephalon

    Författare :My Sjödal; Juha Partanen; Umeå universitet; []
    Nyckelord :telencephalon; olfactory; lens; BMP; RA; FGF; Wnt; development; placode; gradient; chick; nervous system; dorsoventral; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Sammanfattning : The vertebrate nervous system is a highly complex and intriguing structure with diverse functions. To understand the functional nervous system, we first have to be aware of how it is assembled during development. LÄS MER

  4. 13. Molecular and functional anatomy of the mouse olfactory epithelium

    Författare :Viktoria Vedin; Anna Berghard; Urban Lendahl; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; olfactory epithelium; odorant receptor; zone; odorant; gene expression; cell specification; c-Fos; dichlobenil; olfactometry; proliferation; Molecular biology; Molekylärbiologi;

    Sammanfattning : The olfactory system is important for social behaviors, feeding and avoiding predators. Detection of odorous molecules is made by odorant receptors on specialized sensory neurons in the olfactory epithelial sheet. LÄS MER

  5. 14. Neurotoxic Effects of Dichlorophenyl Methylsulphones Related to Olfactory Mucosal Lesions

    Författare :Carina Carlsson; Ingvar Brandt; Hans Tjälve; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; olfcatory toxicity; olfactory bulb; aryl methylsulphone; neurotoxicity; QSAR; Biologi; Biology; Biologi; Ecotoxicology; Ekotoxikologi;

    Sammanfattning : This thesis deals with the highly potent olfactory mucosa toxicant 2,6-dichlorophenyl methylsulphone (2,6-diClPh-MeSO2) and its non-toxic 2,5-chlorinated isomer (2,5-diClPh-MeSO2). In mice, both substances bind firmly in the olfactory mucosa and the olfactory bulb, which are important components of the sensory system. LÄS MER

  7. 15. From sequence to function : Comparative studies of insect olfactory receptors

    Författare :Xiaoqing Hou; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Olfactory receptor; Heterologous expression; Pheromone; Plant volatile; Insect;

    Sammanfattning : In insects airborne odors are detected by the odorant receptors (ORs) and ionotropic receptors (IRs), located on the dendritic membrane of the olfactory sensory neurons (OSNs) housed in olfactory sensilla. The OR and IR gene families show high plasticity in lineage expansion and contraction following the birth-and-death evolutionary model. LÄS MER
