  1. 1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Emma Olofsson; [2023-06-22]
    Nyckelord :Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

    Sammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER

  3. 2. Characterization of diazepam binding inhibitor as a structure-function tool for human ɣ-aminobutyric acid-A receptors

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Szabolcs Simon-Guth; [2023]
    Nyckelord :γ-Aminobutyric acid sub-type A receptors; diazepam binding inhibitor; receptor modulation; recombinant protein expression; two-electrode voltage clamp; dose-response curve; Gammaaminosmörsyrareceptor typ A; Diazepambindande hämmare; receptormodulering; reckmbinant proteinexpression; spänningsklämma med två elektroder; dosresponskurva;

    Sammanfattning : Gammaaminosmörsyrareceptorer typ A (GABAAR) är pentameriska ligandstyrda kloridkanaler som uppvisar neurohämmande egenskaper. Därmed är de primära läkemedelsmål för flera ångestdämpande och lugnande läkemedel som används för att minska förekomsten av aktionspotential i neuroner. LÄS MER

  4. 3. Predicting the outcome of IVF treatments using forward selection regression and linear discriminant analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Agnes Ekman; Linnéa Fahlberg; [2022]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : As more and more In Vitro Fertilizaiton (IVF) treatments are performed each year, there is a need to better predict the outcomes of different stages of the treatment and hence get a better understanding of which hormonal and physical parameters affect the treatment outcome and in what way. In this study, the effect of interaction between baseline AMH (anti-mullerian hormone) and DFI (DNA fragmentation index) on the chance of obtaining at least one good quality embryo was investigated, but no significance was found.

  5. 4. Modulation of a model ligand-gated ion channel by amphetamine derivatives

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturbiologi

    Författare :Emelia Karlsson; [2022]
    Nyckelord :pentameric ligand-gated ion channels; sTeLIC; electrophysiology; psychostimulants; amphetamine derivatives;

    Sammanfattning : Pentameric ligand-gated ion channels are critical mediators of electrochemical signal transduction in neurons and other excitable cells, causing them to be important targets of psychoactive drugs. Structural data for these complex proteins are limited, particularly among eukaryotic family members and for the functionally critical open state. LÄS MER

  7. 5. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Anna Kotila-Ioannou; [2022]
    Nyckelord :Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

    Sammanfattning : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. LÄS MER
