1. Protein Modifications by Low Molecular Weight Chemicals Inducing Airways Diseases
Sammanfattning : Airways diseases are one of the most common health effects in the western world today. It has been shown that low molecular weight chemicals (LMWC) can cause airways diseases. The mechanisms for these diseases are not well known in most cases. Also, methods for biological monitoring of exposure are not available for many of these LMWC. LÄS MER
2. Relationship between chemical structure and airway sensitizing potential for organic acid anhydrides : an animal model
Sammanfattning : Oranic acid anhydrides (OAAs) are important reactive, low-molecular-weight industrial chemicals which induce allergic rhinitis and asthma in exposed subjects. Specific IgE has been demonstrated in a large proportion of OAA-exposed workers. LÄS MER
3. Lignin Conversion to Value-Added Small-Molecule Chemicals : Towards Integrated Forest Biorefineries
Sammanfattning : Lignin is the most abundant aromatic biopolymer on Earth and has significant potential as a feedstock for industrial use. Due to its intrinsic heterogeneity and recalcitrance, lignin has been regarded as a low-value side-product in the pulp and paper industry and in second-generation biorefineries. LÄS MER
4. The Use of Lignin Derivatives to Improve Selected Paper Properties
Sammanfattning : Ved består huvudsakligen av tre typer av polymerer, cellulosa, hemicellulosa och lignin. Lignin bildas i naturen genom enzymatiskt initierad oxidativ koppling av tre olika typer av fenylpropan-enheter. Dessa bygger genom olika kol-kol- och kol-syre-bindningar upp en amorf tredimensionell polymer. LÄS MER
5. Protein adducts of hexahydrophthalic anhydride- chemical structures and biomarkers
Sammanfattning : Organic acid anhydrides (OAAs) are low molecular weight chemicals used in the industry for manufacturing of plastics such as epoxy resins. Exposure to these chemicals may lead to symptoms from the eyes and the respiratory tract in form of conjunctivitis, rhinitis and asthma. LÄS MER
