  2. 1. Mass Spectrometry of Biologically Active Small Molecules : Focusing on polyphenols, alkaloids and amino acids

    Author : Zdeněk Spáčil; Leopold L. Ilag; Frantisek Turecek; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LC-MS; LDI; Mass spectrometry; HPLC; UHPLC; polyphenols; phenolic acids; BMAA; Separation methods; Separationsmetoder; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The foci of this dissertation are on advanced liquid chromatography (LC) separation and mass spectrometry (MS) techniques for the analysis of small bioactive molecules. In addition to discussing general aspects of such techniques the results from analyses of polyphenols (PPs), alkaloids and amino acids published in five appended studies are presented and discussed.

  4. 2. Contact Allergy to Textile Dyes - Clinical and Chemical Studies on Disperse Dyes

    Author : Kristina Morgardt-Ryberg; Yrkes- och miljödermatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disperse Blue 106; contact allergy; Disperse Orange 3; disperse dyes; Disperse Blue 124; TLC; textile-related skin problems; textile dye mix; PPD; HPLC; impurities;

    Abstract : Disperse dyes are common sensitizers among textile dyes. Contact allergy to disperse dyes has been documented in studies carried out in southern Europe, however, corresponding studies have not been performed in the Scandinavian countries. READ MORE

  5. 3. Contact allergy to textile dyes. Clinical and experimental studies on disperse azo dyes

    Author : Laura Malinauskiene; Yrkes- och miljödermatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disperse Orange 1; Disperse Yellow 3; metabolites; azo reduction; p-aminodiphenylamine; 4-nitroaniline; 2-amino-p-cresol; 4-aminoacetanilide; TLC; HPLC; guinea pig maximisation test.;

    Abstract : Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in textile dyeing today. READ MORE

  6. 4. Mycotoxins in indoor environments. Determination using mass spectrometry

    Author : Erica Bloom; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas chromatography; Mass spectrometry; Mycotoxin; Indoor Air; Ergosterol.; Mold; High pressure liquid chromatography; Dust; Building materials;

    Abstract : Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. READ MORE

  7. 5. Gas-sensors for Automobile Interiors

    Author : Eva-Lotta Kalman; Haugen John-Erik; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The concentration of pollutants in the car compartment air is influenced not only by neighboring vehicles, but also by pollutants originating from the car's interior trim materials. These pollutants may cause nuisance and even pose a safety risk as some condense on the windscreen and form an oily film that dims the screen. READ MORE
