  1. 1. Exploring Catalytic Tellurium-Based Antioxidants : Synthesis and Evaluation

    Författare :Jia-fei Poon; Lars Engman; John Murphy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; radical-trapping; chain-breaking; ROS; glutathione peroxidase; tocopherol; aromatic amine; oxidative stress;

    Sammanfattning : This thesis is concerned with the synthesis and evaluation of various tellurium-based chain-breaking antioxidants. The purpose is to find novel regenerable compounds with improved radical-trapping capacity.In the first part of this work, we explore the possibilities to incorporate tellurium into tocopherols and aromatic amines.

    Författare :Jakob Dahlin; Gunnar Skarping; Robert P. Streicher; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. 3. Bioactivation and binding of polycyclic aromatic hydrocarbons in blood vessel endothelia

    Författare :Lizette Granberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Polycyclic aromatic hydrocarbon; PAH; endothelial cells; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants formed by incomplete combustion of organic materials such as fossil fuels and wood. Experimental and epidemiological studies indicate that PAHs may be involved in the development of cardiovascular disease. LÄS MER
