  1. 1. Microfluidic bases sample preparation for blood stream infections

    Författare :Sahar Ardabili; Aman Russom; Mats Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sample-preparation; microfluidics; sepsis; size-based separation; selective cell-lysis; immune-based isolation; Biotechnology; Bioteknologi;

    Sammanfattning : Microfluidics promises to re-shape the current health-care system by transferring diagnostic tools from central laboratories to close vicinity of the patient (point-of-care). One of the most important operational steps in any diagnostic platform is sample preparation, which is the main subject in this thesis. LÄS MER

  2. 2. On Transcriptome Sequencing

    Författare :Daniel Klevebring; Joakim Lundeberg; Ulf Gyllensten; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transcriptome; RNA-seq; DNA sequencing; gene expression profiling; non-coding RNA; small RNA; Functional genomics; Funktionsgenomik; Bioinformatics; Bioinformatik; Genetics; Genetik; Molecular biology; Molekylärbiologi; Cell biology; Cellbiologi;

    Sammanfattning : This thesis is about the use of massive DNA sequencing to investigate the transcriptome. During recent decades, several studies have made it clear that the transcriptome comprises a more complex set of biochemical machinery than was previously believed. LÄS MER

  3. 3. On-line Sample Pretreatment Based on Membrane Enrichment, Mainly Using Supported Liquid Membranes, for Chromatographic Analysis

    Författare :Yin Shen; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological Sample; Environmental Sample; Capillary Gas Chromatography; Ion Chromatography; Automation; Sample Pretreatment; Enrichment; Membrane; Extraction; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The main objective of this work was to construct practical analytical systems for the analysis of environmental and biological samples, using membrane-based techniques for sample pretreatment and chromatography for final analysis. Two types of membrane processes have been applied, with emphasis on automation. LÄS MER

  4. 4. Spatial analysis of lipids in tissue samples applying mass spectrometry imaging

    Författare :Masoumeh Dowlatshahi Pour; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SIMS; MALDI; Mass spectrometry imaging; Lipid; ME-SIMS; Sample preparation;

    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

  5. 5. Phylogenetic Relationships of Silene sect. Melandrium and Allied Taxa (Caryophyllaceae), as Deduced from Multiple Gene Trees

    Författare :Anja Rautenberg; Bengt Oxelman; Mikael Thollesson; Magnus Lidén; Freek Bakker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silene; Elisanthe; Melandrium; Conoimorpha; Caryophyllaceae; Silene multinervia; relative dating; extreme substitution rates; phylogeny; BEST; BEAST; cpDNA; mtDNA; RNA polymerase; RPA2; RPB2; RPD2; SlX1; SlY1; ITS; introgression; incongruent phylogenies; chromosome count; coalescent; Bayes Factors; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

    Sammanfattning : This thesis focuses on phylogenetic relationships among some of the major lineages in Silene subgenus Behenantha (Caryophyllaceae) using DNA sequences from multiple, potentially unlinked gene regions from a large taxonomic and geographic sample. Both traditional phylogenetic analyses and a strategy to infer species trees and gene trees in a joint approach are used. LÄS MER
