  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. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  4. 3. Protein Recovery from Alkaline Extracts: A Comparative Analysis of Isoelectric Precipitation and Ultrafiltration

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Anjay Sharma; [2023]
    Nyckelord :Rapeseed cake; Brewers spent grains; Protein recovery; Ultrafiltration; Alkaline extraction; Food engineering; Technology and Engineering;

    Sammanfattning : Proteins are one of three macro-components of a diet. An increasing demand for products that can be a complete protein source exists. The vulnerability of the current food system towards environmental impacts and the inability to keep up with the rising population has shifted the focus on valorising underutilised by-products of the food industry.

  5. 4. Identification of Lactobacillus species in honey using 16S rRNA gene sequencing

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Robherta Ferreira de Vilcinskas; [2022]
    Nyckelord :;

    Sammanfattning : Honey is a natural product composed of numeral substances and microorganisms. Although honey presents physicochemical properties that confer antimicrobial characteristics, certain microorganisms are still able to survive and multiply in honey. LÄS MER

  7. 5. Evaluation of preanalytical variables for frozen Activated Partial Thromboplastin Time samples

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Natalie Sundberg; [2022]
    Nyckelord :APTT; thawing conditions; centrifugation; pre-analysis; 3; 2% sodiumcitrate plasma;

    Sammanfattning : Activated Partial Thromboplastin Time (APTT) is a screening method used to detect defects in the intrinsic pathway. Different preanalytical variables such as centrifugation and thawing can affect the given test results from APTT analysis. LÄS MER
