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

    University essay from SLU/Dept. of Clinical Sciences

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. Of Plant Biology

    Author : Mohammad Foteh Ali; [2021]
    Keywords : Endosperm development; Parental conflict; Genetic diversity; Auxin;

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

    University essay from Uppsala universitet/Institutionen för kvinnors och barns hälsa

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

    Abstract : 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.

  4. 4. Targeting the zebrafish eye using deep learning-based image segmentation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Joakim Holmberg; [2020]
    Keywords : ;

    Abstract : Researchers studying cardiovascular and metabolic disease in humans commonly usecomputer vision techniques to segment internal structures of the zebrafish animalmodel. However, there are no current image segmentation methods to target theeyes of the zebrafish. READ MORE

  5. 5. Characterizaion of the mechanism underlying auxin-induced seed arrest in Arabidopsis thaliana

    University essay from SLU/Dept. Of Plant Biology

    Author : Sowmiya Devi Venkatesan; [2020]
    Keywords : endosperm; hybridization barriers; triploid block; auxins; RNA Polymerase IV; RNA silencing;

    Abstract : In flowering plants, seeds are produced as a result of double fertilization, whereby the haploid egg cell and the diploid central cell fuse with one of the two haploid sperm cells giving rise to a diploid embryo and a triploid endosperm, respectively. The endosperm serves as the major nutrient source for the developing embryo yet the molecular mechanisms pertaining to its development are not fully understood. READ MORE
