1. Tools for applied soft ionization mass spectrometry
Sammanfattning : Mass spectrometry (MS) is an important analytical tool. Its most importantadvantages are sensitivity, resolution, and accurate and precise m/zmeasurements. To get the best results from an instrument, the user musthave knowledge of its limitation and requirements. LÄS MER
2. Advances in analytical methodologies for studies of the platinum metallome in malignant cells exposed to cisplatin
Sammanfattning : The scientific progress about the important chemotherapeutic drug substance cisplatin (CDDP) and its function has often been rendered by data difficult to interpret, and still many questions about its mode of action remains to be clarified by the scientific community. However, studies of CDDP possess a high complexity due to; i) low intracellular concentration, ii) many potential biomolecule targets, iii) poor or unknown stability of the intact drug and its biomolecule adducts and iv) complex and varying sample matrices.

3. Hydroxamate Siderophores and Low Molecular Mass Organic Acids in Terrestrial and Aquatic Environments Determined by Liquid Chromatography Mass Spectrometry
Sammanfattning : Siderophores are low molecular mass organic compounds with high iron(III) stability constants. They are produced by many microorganisms, often in combination with low molecular mass organic acids (LMMOAs). Both siderophores and LMMOAs accelerate mineral weathering, thereby enhancing mineral nutrient availability. LÄS MER
4. The structural diversity of lipopolysaccharides expressed by genetically defined clinical isolates of nontypeable Haemophilus influenzae
Sammanfattning : Nontypeable Haemophilus influenzae (NTHi) is an important cause of otitis media and respiratory tract infections. Its lipopolysaccharide (LPS) molecule, an outer membrane component, is a major virulence factor of NTHi. The LPS molecule may also be an efficient target for antibodies which might be protective against NTHi disease. LÄS MER
