  1. 16. Quantitative monitoring of microorganisms in environmental samples using biomarkers

    Författare :Annelie Elväng; James Prosser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : The use of microorganisms in environmental biotechnology is an area of growing interest. Microorganisms have been used for diverse applications, such as biological fertilizers, biological pesticides and bioremediation of toxic chemicals. In many cases, the bacteria of interest have been genetically alterred to improve certain traits. LÄS MER

  3. 17. Treatment of helicobacter pylori infection : experimental and clinical studies

    Författare :Mikael Sörberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Helicobacter pylori; coccoid form; treatment; pharmacodynamics; resistance; serology Stockholm 1997;

    Sammanfattning : The general aims of the present study were to investigate the reason for failed H. pylori eradication, and to improve the recommendations for treating H. pylori infection. Our in vitro studies are based on microscopy, viable count and bioluminescence assay of bacterial adenosine triphosphate (ATP). LÄS MER

  4. 18. ADP regulation of insulin secretion and beta-cell apoptosis

    Författare :Chanyuan Tan; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P2Y; β-cell; ADP; insulin; apoptosis; autocrine; ectonucleotidase;

    Sammanfattning : The aims of this dissertation were to investigate the effects of extracellular purines on insulin secretion, and apoptosis in mouse pancreatic islets and β-cells; to examine if high glucose and free fatty acids induces β-cell apoptosis via autocrine effects of ADP acting on the P2Y13 receptor; and to investigate the modulation of extracellular purines in vascular smooth muscle cells (VSMCs) through ectonucleotidase or ATP release under the effect of high glucose. The expression of the ADP receptors P2Y1 and P2Y13 were shown in both mouse pancreatic islets and isolated β-cells using real-time PCR quantification. LÄS MER

  5. 19. Approaches for analysis of mutations and genetic variations

    Författare :Afshin Ahmadian; KTH; []
    Nyckelord :LOH; microsatellite; fragment analysis; DNA sequencing; pyrosequencing; cancer; mutation; variation; SNP; allele-specific extension; apyrase; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Detecting mutations and genomic variations is fundamental indiagnosis, isolating disease genes, association studies,functional genomics and pharmacogenomics. The objective hasbeen to use and further develop a variety of tools andtechnologies to analyze these genetic alterations andvariations. LÄS MER

  7. 20. Energy metabolism and angiogenesis in atherosclerosis and cancer

    Författare :Matias Ekstrand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Energy metabolism; Hypoxia; Reactive oxygen species; Intussusceptive angiogenesis;

    Sammanfattning : Energy metabolism requires supply of glucose and oxygen. In atherosclerotic plaques and cancer tumors, there are local areas with mismatch in demand and supply of oxygen and nutrients. The resulting cellular energy imbalance may promote energy failure and stimulation of angiogenesis. LÄS MER
