  1. 1. Isolation, Synthesis and Structure-Activity Relationships of Antifeedants against the Pine Weevil, Hylobius Abietis

    Författare :Carina Eriksson; Christina Moberg; John Pickett; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pine weevil; Hylobius abietis; semiochemicals; antifeedant; feeding deterrent; feeding stimulant; bark extract; carboxylic acid; piperidine alkaloids; structure-activity; cinnamic aldehyde; benzaldehyde; Organic chemistry; Organisk kemi;

    Sammanfattning : The large pine weevil, Hylobius abietis L., is a major insect pest on conifer seedlings in northern Europe. Due to its feeding newly planted trees get girdled, resulting in high seedling mortality (up to 80%). As a consequence great financial losses to the forest industry occur. LÄS MER

  2. 2. Epoxides as Contact Allergens - Formation, Sensitising Potency and Structure-Activity Relationships

    Författare :Ida Belogorcev Niklasson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergic contact dermatitis; Autoxidation; Bioactivation; Cinnamic alcohol; Diglycidyl ether of bisphenol A DGEBA ; Epoxide; Epoxy resin; Local lymph node assay; Polymerisation; Peptide reactivity; Prehapten; Prohapten; Sensitisation; Skin; Structure-Activity Relationship; Thermogravimetric Analysis;

    Sammanfattning : Chemicals in our environment with which we have repeated skin contact can cause skin sensitisation (contact allergy). To trigger an immune response a compound (hapten) must be able to penetrate the skin, where it needs to be reactive enough to bind to proteins and form immunogenic complexes that are recognised as foreign.

  3. 3. Mass Spectrometry Strategies for Characterization of Contact Allergens and their Protein Conjugates in Vitro and in Vivo

    Författare :Lorena Ndreu; Isabella Karlsson; Margareta Törnqvist; Ulrika Nilsson; Maja Aleksic; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; Skin allergy; Protein Adducts; In vitro methods; Bioanalysis; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Humans are daily exposed to chemicals from various sources, including cosmetics, jewelry, clothes, and hair dyes, which can result in the occurrence of contact allergy and subsequent allergic contact dermatitis (ACD), a type IV delayed hypersensitivity reaction. ACD is characterized by inflammation and eczema at the site of exposure, and no definitive cure for this condition has been identified to date, with only symptomatic treatment options involving corticosteroids being available.

  4. 4. Potential and problems related to reuse of water in households

    Författare :Eva Eriksson; Denmark Technical University of Denmark; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural Science; Naturvetenskap; Technology byts ev till Engineering ; Teknik;

    Sammanfattning : There is a growing demand in society for the introduction of decentralised sanitary reuse systems and the main reason for this is that centralised urban sanitation systems are expensive and resource-intensive. A second is water shortage and one way to reduce the need for freshwater is to reuse wastewater on-site. LÄS MER
