6. Applications of nanospray desorption electrospray ionization mass spectrometry : In situ lipid and metabolite analysis from cells to tissue
Sammanfattning : Ambient mass spectrometry (MS) has proved to be an important addition to the bioanalytical toolbox. These methods perform analyte sampling and ionization under atmospheric pressure, and require very little sample preparation other than the sampling process in front of the machine. LÄS MER
7. 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
8. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides
Sammanfattning : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. LÄS MER
9. Mass spectrometry based analysis of endogenous sterols and hormones
Sammanfattning : Bioanalytical applications using supercritical fluid chromatography (SFC) as analytical technique are of increasing interest. In essence, bioanalysis involves measurement of bioactive or endogenous compounds in biological matrices. LÄS MER
10. Targeted analysis of bioactive steroids and oxycholesterols : Method development and application
Sammanfattning : Peripheral steroids and oxycholesterols are important lipid compounds controlling various functions in the human body. Steroid analysis of biological samples is routinely employed in the clinical environment as an essential source of information on endocrine and metabolic disorders. LÄS MER
