  1. 1. 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

  4. 3. Parameterization of state feedback gains for pole assignment

    Författare :Hans Norlander; Bengt Carlsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : The pole assignment problem has been subject for research for a long time. For single-input single-output systems this problem is well understood but for multi-input multi-output systems the pole assignment problem is more complex. LÄS MER

  5. 4. Effects of cold and hand-arm vibration on the peripheral neurosensory and vascular system : an occupational perspective

    Författare :Daniel Carlsson; Jens Wahlström; Tohr Nilsson; Erik Nordh; Hans Pettersson; Tiina Ikäheimo; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hand-arm vibration; Raynaud’s phenomenon; paresthesia; sensation of cold; hand-arm vibration syndrome; quantitative sensory testing; cold sensitivity; cold; cold exposure; frostbite; Sweden; cold injury; military; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Background In Swedish working life, exposure to cold and exposure to hand-arm vibration (HAV) are two common health hazards. Health effects of HAV in the neurosensory, vascular and musculoskeletal systems are collectively denoted hand-arm vibration syndrome (HAVS), and have been thoroughly studied. LÄS MER

  7. 5. Studies of the Ribosomal Protein S19 in Erythropoiesis

    Författare :Hans Matsson; Niklas Dahl; Leif Carlsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; RPS19; Rps19; erythropoiesis; erythroblastopenia; Diamond-Blackfan; anemia; Genetik; Genetics; Genetik;

    Sammanfattning : Ribosomal proteins are components of the ribosome, the protein synthesis machinery. The ribosomal protein S19 gene (RPS19) is mutated in Diamond-Blackfan anemia, DBA, which is a rare congenital anemia with absence or reduction of erythroid precursors in bone marrow. In this thesis, the role of RPS19 in erythropoiesis is investigated. LÄS MER
