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

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Emilie Boson; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

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

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Katharina Stanzel; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

4. 3. AMH i serum och seminalplasma hos hund : association till spermakvalitet

   University essay from SLU/Dept. of Clinical Sciences

   Author : Hannah Olsson; [2021]
   Keywords : AMH; Anti-Müllerskt hormon; hund; berner sennen; spermakvalitet; spermiemotilitet; spermiemorfologi;

   Abstract : Anti-Müllerskt hormon (AMH) har föreslagits som en biomarkör för spermakvalitet, eftersom hormonet produceras av sertolicellen som stödjer spermiernas utveckling. Förändringar i produktion av AMH antas kunna visa på nedsatt funktion i sertolicellen, och på så sätt nedsatt funktion i spermieutvecklingen. READ MORE

5. 4. 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

6. 5. Genetic diversity status and associations with sperm quality characteristics in farmed Arctic charr (Salvelinus alpinus L.) across Sweden

   University essay from SLU/Dept. of Animal Breeding and Genetics

   Author : Anam Anjum; [2020]
   Keywords : Arctic charr; dd-RADseq; genetic diversity; GWAS; reproductive success;

   Abstract : The national breeding programme of Arctic charr (Salvelinus alpinus L.) has been of fundamental importance for the expansion of Arctic charr farming across Sweden. Selection has been ongoing since 1980s documenting approximately 10% improvement per generation regarding growth related traits. READ MORE
