2. Enamel hypomineralization in permanent first molars. A clinical, histo-morphological and biochemical study
Abstract : Hypomineralization in the permanent first molars was common in a group of 516 Swedish 8-year-old children. Ninety-five children (18.4%) had at least one molar with demarcated opacity. The incisors frequently displayed opacities concomitantly. READ MORE

3. High Rate Electron Capture Dissociation Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
Abstract : Advances in science and technology during the past decade have greatly enhanced the level of the structural investigation of macromolecules – peptides and proteins. Biological mass spectrometry has become one of the most precise and sensitive techniques in peptide and protein analysis. READ MORE

4. Mass spectrometry of biopolymers based on ion-induced desorption
Abstract : Various aspects of biopolymer molecular characterization by their molecular masses havebeen studied, with emphasis on ion-induced desorption and time-of-flight mass Spectrometry(TOF MS). Limitations of the average-isotopic mass concept, as well as the utility ofaccurate monoisotopic mass measurements for deriving amino-acid and elementalcompositions, are discussed. READ MORE

5. Secondary and Higher Order Structural Characterization of Peptides and Proteins by Mass Spectrometry
Abstract : The work in this thesis has demonstrated the advantages and limitations of using MS based technologies in protein and peptide structural studies. Tandem MS, specifically electron capture dissociation (ECD) have shown the ability to provide structural insights in molecules containing the slightest of all modifications (D-AA substitution).
