  1. 16. The life cycle and developmental phases of Cambrian-Ordovician organic-walled microfossils from Kolguev Island, Arctic Russia.

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Magdalena Pazio; [2016]
    Nyckelord :Saharidia fragilis; Prasinophyceae algae; life cycle; acritarchs; Saharidia fragilis; Prasinophyceae; livscykel; acritarch;

    Sammanfattning : Light microscopy studies of collections of late Cambrian/Early Ordovician organic-walled microfossils, informally called acritarchs, provide the observations on phenotypic traits that are comparable to Modern microalgae and make possible recognition of various developmental stages in their complex life cycle. The exceptionally preserved Saharidia fragilis microfossils show the internal body within the vesicle and the formation of the fringe and pylome, the opening for releasing of the daughter cells from the phycoma-like cyst.

  3. 17. Modeling of beta-cell Metabolic Activity and Islet Function : a Systems Approach to Type II Diabetes

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Fotios Christakopoulos; [2016]
    Nyckelord :cytoskeleton remodelling; particle tracking microrheology; IAPP; type 2 diabetes;

    Sammanfattning : Diabetes has gained growing attendance as one of the key non communicable diseases (NCD) with the World Health Organization identifying it as the focus of the World Health Day 2016. It is reported that more than 420 million people suffer from diabetes, a number predicted to rise in the coming years. LÄS MER

  4. 18. Investigation of the micelle-to-vesicle transition in mixtures of an anionic and a cationic surfactant: the effect of adding salt

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Josefine Leifsdotter; [2012]
    Nyckelord :SDS; DDAB; NaBr; Static light scattering; cryo-TEM; drug delivery; perforated vesicles; Krafft point;

    Sammanfattning : Catanoinic systems spontaneously form micelles and vesicles, which are self-assembled spherical structures made up by surfactants. In the core of the micelle a drug, or other organic substance, can be kept to stabilize it when placed in an aqueous environment. LÄS MER

  5. 19. Prostasome ELISA - a potential marker for prostate cancer diagnosis

    Uppsats för yrkesexamina på grundnivå, Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Elisabeth Thermaenius; [2012]
    Nyckelord :biomarker; immunoassay; exosome; PSA; vesicle;

    Sammanfattning : Abstract   The prostate gland, a male organ, situated right under the urine bladder, is involved in male reproduction. It can also be the place for more or less serious diseases such as inflammation, abnormal growth and cancer. Especially prostate cancer is very common in the Western world. LÄS MER

  7. 20. Single-step microfluidic generation of cell-sized giant unilamellar vesicles: Characterization and dielectrophoretic patterning and sorting

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Fredrik Thege; [2011]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Giant Unilamellar Vesicles (GUV) have the potential to play a dominating role in future scientific efforts to understand and model biological systems through the creation of artificial cells. GUV:s span a wide range of possible applications that include their use as biosensors, cell encapsulation agents and biomicroreactors. LÄS MER
