1. 1. Cytokine responses in metal-induced allergic contact dermatitis : Relationship to in vivo responses and implication for in vitro diagnosis

   Författare :Jacob Minang; Marita Troye-Blomberg; Niklas Ahlborg; Rik Scheper; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal allergy; Contact dermatitis; cytokines; ELISA; ELISpot; Flow cytometry; Immunology; Immunologi;

   Sammanfattning : Transition metals such as nickel (Ni), cobalt (Co), palladium (Pd), chromium (Cr) and gold (Au) are widely used as alloys in jewelry and biomaterials such as orthodontic and orthopaedic appliances. These metals also cause cell-mediated allergic contact dermatitis (ACD) reactions in a significant proportion of the population upon prolonged direct exposure. LÄS MER

3. 2. Protein structure prediction : Zinc-binding sites, one-dimensional structure and remote homology

   Författare :Nanjiang Shu; Sven Hovmöller; Bruce Donald; Geoff Barton; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; zinc-binding; profile; homology detection; shape string; Bioinformatics; Bioinformatik; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Structural Chemistry; strukturkemi;

   Sammanfattning : Predicting the three-dimensional (3D) structure of proteins is a central problem in biology. These computationally predicted 3D protein structures have been successfully applied in many fields of biomedicine, e.g. family assignments and drug discovery. LÄS MER

4. 3. Contacts on Silicon Carbide by Use of Nickel and Tantalum ---Preparation and Characterisation

   Författare :Yu Cao; Chalmers tekniska högskola; []
   Nyckelord :Keywords: Silicon Carbide; Metal Contact; Thin Films; Preferential Etching; Interfacial Reaction; effect; Nickel; Tantalum; #955; Depth Profile; I-V Characteristics.;

   Sammanfattning : Silicon carbide (SiC) is one of the attractive semiconductors due to its good electrical, thermal and mechanical properties. It is a promising material for high temperature, high power and high frequency application. Reliable electrodes are always necessary to utilise SiC for electronic devices. LÄS MER

7. 5. Long-term metal retention processes in a peat bog : Field studies, data and modelling

   Författare :Kristina Syrovetnik; Ivars Neretnieks; Bert Allard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peat; heavy metals distribution; sequential extraction; binding mechanisms; modelling; metal sulphide oxidation; aqueous composition; sorption; humic substances; ferric oxyhydroxide; Chemical engineering; Kemiteknik;

   Sammanfattning : The study was inspired by the need to assess long-term metal retention in municipal solid waste (MSW) landfills. The long-term processes in landfills are poorly known due to the relatively short time that such landfills have been in existence. Natural analogues where similar metal binding processes could be expected were therefore sought for. LÄS MER
