    Sammanfattning : Amyotrophic lateral sclerosis (ALS), also known as Charcot’s disease, motor neuron disease (MND) and Lou Gehrig’s disease, is a deadly, adult-onset neurodegenerative disorder characterized by progressive loss of upper and lower motor neurons, resulting in evolving paresis of the linked muscles. ALS is defined by classical features of the disease, but may present as a wide spectrum of phenotypes. LÄS MER

  2. 2. Managing and Exploring Large Data Sets Generated by Liquid Separation - Mass Spectrometry

    Nyckelord :Analytical chemistry; liquid chromatography; capillary electrophoresis; capillary electrochromatography; mass spectrometry; electro spray ionization; chemometrics; multivariate data analysis; peptide; biomarkers; fingerprints; PCA; alignment; data compression; ANOVA; target correlation; data management; Analytisk kemi;

    Sammanfattning : A trend in natural science and especially in analytical chemistry is the increasing need for analysis of a large number of complex samples with low analyte concentrations. Biological samples (urine, blood, plasma, cerebral spinal fluid, tissue etc. LÄS MER

  3. 3. Selectivity in NMR and LC-MS Metabolomics : The Importance of Sample Preparation and Separation, and how to Measure Selectivity in LC-MS Metabolomics

    Författare :Albert Elmsjö; Curt Pettersson; Torbjörn Arvidsson; Thomas Moritz; Uppsala universitet; []

    Sammanfattning : Until now, most metabolomics protocols have been optimized towards high sample throughput and high metabolite coverage, parameters considered to be highly important for identifying influenced biological pathways and to generate as many potential biomarkers as possible. From an analytical point of view this can be troubling, as neither sample throughput nor the number of signals relates to actual quality of the detected signals/metabolites. LÄS MER

  4. 4. Metabolic variation in autoimmune diseases

    Författare :Rasmus Kirkegaard Madsen; Johan Trygg; Thomas Moritz; Torbjörn Lundstedt; Matej Oresic; Umeå universitet; []
    Nyckelord :Rheumatoid Arthritis; Diabetes Mellitus type 1; Metabolic Profiling; Metabolomics; Chemometrics; Multivariate Data Analysis; Mass Spectrometry; biologisk kemi; biological chemistry;

    Sammanfattning : The human being and other animals contain immensely complex biochemical processes that govern their function on a cellular level. It is estimated that several thousand small molecules (metabolites) are produced by various biochemical pathways in humans. LÄS MER

  5. 5. Multivariate data analysis of metabolomic multi-tissue samples

    Författare :Frida Torell; Johan Trygg; Torbjörn Lundstedt; Thomas Moritz; Kate Bennett; Michal Daszykowski; Umeå universitet; []

    Sammanfattning : Multi-tissue metabolomics involves characterisation of the metabolome of several tissue types. The metabolome consists of small chemical entities of low molecular weight called metabolites, which are constantly produced and interchanged through a vast variety of biochemical reactions occurring throughout living organisms.
