    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Fysikalisk kemi; biopolymers; Polymer technology; nanoparticles; Lipid; triblock copolymer; surfactants; Nonionic; Vesicles; Formation; Physical chemistry;

    Abstract : Popular Abstract in Swedish En amfifil molekyl innebär en molekyl som består av två delar, en som är hydrofil (“vattenälskande”) och en som är hydrofob (“vattenhatande”). Ofta består den amfifila molekylen av en ”vattenälskande” huvudgrupp och en ”vattenhatande” svans och kallas för surfaktant. READ MORE

  2. 2. Tethered Lipid Vesicles as Nanoscale Sensor Elements

    University dissertation from Karin Bryskhe, Villav. 8, 232 53 Åkarp

    Author : Seyed Tabaei; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aquaglyceroporin; lipid vesicles; total internal reflection fluorescence TIRF microscopy; cell membrane; aquaporin; pore formation; surface plasmon resonance SPR ; phospholipase A2; antiviral peptide; lipid bilayer; biosensing; microfluidics;

    Abstract : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.

  3. 3. Prostasomes as Diagnostic, Prognostic and Therapeutic Vesicles

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Louise Dubois; Uppsala universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exosomes; Prostasomes; Lipid rafts; Bioengineered vesicles; Prostate cancer; Purinergic receptors; Thymidine kinase 1; Medical Biochemistry; Medicinsk biokemi;

    Abstract : This thesis explores prostasomes and their ability to be used as a new diagnostic tool for prostate cancer. Alongside diagnosis, this thesis also suggests prostasomes as a tool for prognosis and therapeutic treatment in patients with prostate cancer. READ MORE

  4. 4. Roles of membrane vesicles in bacterial pathogenesis

    University dissertation from Umeå : Umeå University

    Author : Svitlana Vdovikova; Umeå universitet.; Umeå universitet.; Umeå universitet.; [2017]

    Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

  5. 5. Cellular responses to amyloid-beta protofibrils Focus on astrocytes, extracellular vesicles and antibody treatment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elisabeth Nikitidou; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

    Abstract : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. READ MORE
