  2. 1. Aerosols of Isocyanates, Amines and Anhydrides : Sampling and Analysis

    Author : Jakob Dahlin; Gunnar Skarping; Robert P. Streicher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; isocyanate; amine; aminoisocyanate; organic acid anhydride; denuder; impactor; impinger; air sampling; LC-MS; LC-CLND; di-n-butylamine; DBA; thermal degradation; aerosol; particles; TDI; MDI; HDI; ICA; MIC; IPDI; exposure; occupational health; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : This thesis presents methods for air sampling and determination of isocyanates, amines, aminoisocyanates and anhydrides. These organic compounds are generated during thermal degradation of polymers such as polyurethane (PUR) or epoxy.Isocyanates, amines and anhydrides are airway irritants known to cause occupational asthma.

  4. 2. Isocyanates - methodology for gas and particle generation, sampling and detection

    Author : Daniel Gylestam; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Dhimiter Bello; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isocyanate; PUR; Dry sampler; PTR-MS; Transfer line; PPE; Environmental Chamber; Respirable Particles; Denuder Impactor; Aerosol; Particles; Impinger; air sampling; LC-MS; di-n-butylamine; DBA; ICA; MIC; HDI; TDI; IPDI; MDI; Occupational Exposure; Exposure; Occupational Health; Analytical Chemistry; analytisk kemi;

    Abstract : Isocyanates are mainly used in the industry for the production of polyurethane (PUR) plastics. Workers are at risk of being exposed during the manufacturing of PUR. During thermal degradation of PUR, isocyanates are released and workers involved in hot work such as fire-fighting, welding etc. may also be exposed. READ MORE

  5. 3. Biological and air monitoring of exposure to isocyanates

    Author : Carl Johan Sennbro; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; industrial medicine; Occupational health; asthma; protein adducts; polyurethane; biomarkers; occupational exposure; DBA; ICA; NDI; MDI; TDI; Diisocyanates; Isocyanates; Biomonitoring; Air monitoring; arbetsmiljömedicin; Yrkesmedicin;

    Abstract : Exposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. READ MORE

  6. 4. Pathogenesis of myelin oligodendrocyte glycoprotein induced experimental autoimmune encephalomyelitis in DBA/1 mice

    Author : Khairul-Bariah Abdul-Majid; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Experimental autoimmune encephalomyelitis (EAE) is an animal model of the human autoimmune disease, multiple sclerosis (MS). MS is prevalent among the Caucasian population and linkage analysis studies have indicated that the presence of certain MHC class II genes can increase the risk of manifesting MS. READ MORE

  7. 5. Diamond-Blackfan Anemia: Erythropoiesis Lost in Translation

    Author : Johan Flygare; Stefan Karlsson; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Hematologi; Haematology; RNA interference; Erythropoiesis; Lentiviral vectors; Nucleolus; Diamond-Blackfan anemia; Gene therapy; extracellulära vätskor;

    Abstract : Diamond-Blackfan anemia (DBA) is a congenital erythroid aplasia that usually presents as macrocytic anemia during infancy. Linkage analysis suggests that at least four genes are associated with DBA of which two have been identified so far. READ MORE
