1. Spatial analysis of lipids in tissue samples applying mass spectrometry imaging
Sammanfattning : Lipids are important naturally occurring components in all living cellular organisms. They serve as the main building blocks of cellular membranes, participate in many signaling pathways and are also stored as an energy source. LÄS MER
2. Quantitative applications of secondary ion mass spectrometry : solid-state diffusion and mass fractionation studies
Sammanfattning : .... LÄS MER
3. Enamel hypomineralization in permanent first molars. A clinical, histo-morphological and biochemical study
Sammanfattning : 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. LÄS MER
4. Molecular and epidemiological studies on eyes with pseudoexfoliation syndrome
Sammanfattning : Pseudoexfoliation (PEX) syndrome is an age-related condition characterized by the production and accumulation of extracellular fibrillary material in the anterior segment of the eye. PEX predisposes for several pathological conditions, such as glaucoma and complications during and after cataract surgery. LÄS MER
5. Single fluid inclusion analysis using ToF-SIMS : Implications for ancient Earth biodiversiy and paleoenvironment studies
Sammanfattning : When and how life first emerged on the Earth is an area of intense research. Signs of the first life on Earth, including morphological fossils, are scarce and hard to interpret. An alternative approach is to study organic biomarkers, which are molecular fossils commonly considered as bona fide biosignatures. LÄS MER
