  1. 1. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Författare :Josef Azem; Göteborgs universitet.; University of Gothenburg.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN; MEDICINE; Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Sammanfattning : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. LÄS MER

  4. 4. Single Molecule Detection Microfluidic Automation and Digital Quantification

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Malte Kühnemund; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single molecule; digital; rolling circle amplification; magnetic particle; padlock probe; microfluidics; resistive pulse sensing; lab on chip; mobile phone microscopy; enrichment; sequencing;

    Sammanfattning : Much of recent progress in medical research and diagnostics has been enabled through the advances in molecular analysis technologies, which now permit the detection and analysis of single molecules with high sensitivity and specificity. Assay sensitivity is fundamentally limited by the efficiency of the detection method used for read-out. LÄS MER

    Sammanfattning : Since the first successful derivation of human embryonic stem cells (hESC), rapid progress has been attained in the development of strategies in differentiation of these cells into various neural lineages, with the fundamental objective of using these cells for replacement and repair of damaged neuronal circuits in the central nervous system (CNS). Of particular interest are midbrain dopaminergic (mDA) neurons, which play a central role in regulation of voluntary movement. LÄS MER
