  1. 1. The Examination of Alternative Methods for Sperm Cell Lysis and Purification of Sexual Assault Samples

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Emilie Boson; [2023]
    Nyckelord :Differential lysis; Differential extraction; Sexual assault samples; Sperm cells; Forensic; DNA recovery; DNA profiling; DNA purification; Applied microbiology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. LÄS MER

  3. 2. Investigation of the interaction of A-MYB and TCFL5 on pachytene PIWI-interacting RNA genes in two sub-species of mice, mus musculus musculus and mus musculus castaneus

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Most Shova Banu; [2023]
    Nyckelord :;

    Sammanfattning : Spermatogenesis is a complex process that involves the production of sperm cells from germ cells in order to transmit genetic information to progeny. The PIWI-interacting RNA (piRNA) is a non-coding small silencing RNA that guides the PIWI protein to silence target transposon transcripts to regulate the production of germ cells. LÄS MER

  4. 3. Single-cell transcriptomic and antibody-based proteomic analysis of Sertoli cell-specific markers in human testis

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Katharina Stanzel; [2023]
    Nyckelord :;

    Sammanfattning : The testis is a complex organ responsible for sperm production and hormone synthesis. Spermatogenesis, the process of sperm formation, occurs in the seminiferous tubules and involves the coordinated development of germ cells with the support of Sertoli cells. LÄS MER

  5. 4. The Role of Perfluoroalkyl Substances (PFAS) contaminated food for male infertility : A Scoping review

    Master-uppsats, Linnéuniversitetet/Institutionen för hälso- och vårdvetenskap (HV)

    Författare :Tehseen Kamran; [2023]
    Nyckelord :Per-or polyfluoroalkyl substances; diet; food; male infertility;

    Sammanfattning : Background: The trend of male infertility is increasing and it correlates with industrial development which has introduced various industrial contaminants in the environment and human life. PFASs are one of those contaminants. Humans are exposed to PFAS through various routes and sources, especially through food and diet. LÄS MER

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

    Master-uppsats, SLU/Dept. Of Plant Biology

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

    Sammanfattning : 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. LÄS MER
