    Sammanfattning : New biomarkers are needed to improve knowledge about pathophysiology, in order to provide earlier correct diagnosis and to follow disease progression of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). The aim of this thesis was to find new biomarkers for these diseases. LÄS MER

    Sammanfattning : Advances in life science require knowledge of active molecules in complex biological systems. These molecules are often only present for a certain time and at limited concentrations. LÄS MER

  4. 13. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

    Författare :Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

    Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER

  5. 14. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism

    Författare :Oleksii Rebrov; Mats Larsson; Richard Thomas; Vitali Zhaunerchyk; Anne Zehnacker-Rentien; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Sammanfattning : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. LÄS MER

  7. 15. Characterization of dissolved organic matter : An analytical challenge

    Författare :Claudia Patriarca; Jonas Bergquist; Lars Tranvik; Jeffrey A. Hawkes; Jonathan Martin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : Dissolved organic matter (DOM) is the prevalent form of organic carbon in most aquatic environments. It is an ultra-complex mixture that plays a crucial role in global carbon cycling. Despite its importance it is still poorly understood due to its extreme heterogeneity and intricacy. LÄS MER
