  1. 1. Per- and polyfluoroalkyl substances (PFAS) and the effect on apoptosis in early porcine embryo development in vitro

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Anna Leclercq; [2021]
    Nyckelord :apoptosis; PFAS; PFOS; PFHxS; IVF; IVP; porcine; pig; embryo; TUNEL; reproduction;

    Sammanfattning : The aim of this study was to evaluate the effects of PFHxS (perfluorohexane sulfonic acid) and PFOS (perfluorooctane sulfonic acid) on early embryo development parameters and apoptosis on day 6 post fertilization in porcine embryos. A second purpose was to evaluate, and establish, the TUNEL assay in our IVF laboratory. LÄS MER

  2. 2. Endosperm-based postzygotic hybridization barriers in Arabidopsis and Capsella

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Mohammad Foteh Ali; [2021]
    Nyckelord :Endosperm development; Parental conflict; Genetic diversity; Auxin;

    Sammanfattning : In Arabidopsis, endosperm development is very important for viable seed development. Especially, endosperm cellularization is a crucial event for embryo survival and if it fails, can lead to embryo arrest, as observed in seeds derived from interploidy and interspecies hybridization.

  3. 3. Assessment of zebrafish embryo toxicity of environmentally relevant antibiotics

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Ophelia Mastrangeli; [2021]
    Nyckelord :zebrafish embryo; toxicity; antibiotics; FET; Fish embryo toxicity; Bioaccumulation; zebrafiskembryo; toxicitet; antibiotika; FET; Bioackumulering;

    Sammanfattning : Antibiotics are essential drugs in modern medicine. After consumption antibiotics are excreted in unmetabolized form in the urine and reach our sewage treatment plants (STP). STP are not able to degrade all antibiotics leading to release of antibiotics into the aquatic environment. Aquatic animals are thus continuously exposed to antibiotics. LÄS MER

  4. 4. CRYOPRESERVATION OF HUMAN BLASTOCYSTS, A COMPARISON OF TWO VITRIFICATION AND WARMING KITS

    Kandidat-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Författare :Sara Ottersgård; [2020]
    Nyckelord :Irvine Scientific; Kitazato; human embryos; embryo development; blastocyst scoring;

    Sammanfattning : Infertility is a widespread problem around the world, although the available treatment options constantly improve through research and methodological development. A common treatment option mainly for biologically caused infertility is in-vitro fertilization, where in a menstrual cycle multiple oocytes are stimulated to mature and are then fertilized in a laboratory.

  5. 5. Spånga stadshus

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Einar Stenberg; [2020]
    Nyckelord :Spånga; City hall; concrete; translucent; contemporary architecture;

    Sammanfattning : Spånga är en liten förort till Stockholm med totalt 20 000 invånare. Till största del är spånga ett kluster av olika villaområden som tillsammans knyts samman av ett mindre centrum vars plan växt fram från Spånga station. Spånga centrum har en lummig småstadskaraktär. LÄS MER
