  1. 1. 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

  3. 2. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Author : Christopher Hampton; [2019]
    Keywords : ;

    Abstract : While endocrine disrupting chemicals have become a serious concern in human and environmental toxicology, many of the methods used for investigating developmental toxicity require long exposure periods, and thus can be technically challenging, labour intensive and expensive. For example, the current standard method, the Larval Amphibian Growth and Development Assay (LAGDA) has an exposure period of ³130 days. READ MORE

  4. 3. Analysis of somatic mutations in papillomavirus positive tumours from younger and older oropharyngeal cancer patients

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Andreas Ährlund-Richter; [2016]
    Keywords : ;

    Abstract : ABSTRACT Background: Human Papilloma Virus positive (HPV+) Oropharyngeal Squamous Cell Carcinoma (OSCC), dominated by tonsillar cancer (TSCC) and base of tongue cancer (BOTSCC) has low mutation-frequency and better survival for younger than older patients.Aim: To examine if HPV+ TSCC and BOTSCC have distinct gene-mutation profiles, for 50 often-mutated genes in cancer, in younger compared to older patients and to test and compare different variant callers to get a deeper understanding of the data.

  5. 4. Counting Sertoli Cells in Thin Testicular Tissue

    University essay from Institutionen för informationsteknologi

    Author : Abdolrahim Kadkhodamohammadi; [2012]
    Keywords : ;

    Abstract : This master thesis develops a novel system to model the tubular structure in thin sections of testicular tissue and count the Sertoli cells. A three-phase method is proposed to model the tubular structure in microscopic images of the tissue, the model is deployed to detect the cells. READ MORE

  6. 5. Molecular systematics: data mining of canine endogenous retroviruses, CFERV

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

    Author : Marie Ekerljung; [2007]
    Keywords : DNA; germ cell; transposable elements; canine endogenous retroviruses CFERV ; horisontal contagion;

    Abstract : Endogenous retroviruses (ERVs) were discovered in the 1960s and in their complete form they consist of two LTRs (long terminal repeat sequences) that are each located on either side of the chain/element. ERVs contain the following genes: gag, pro, pol and env . READ MORE
