  1. 11. PREPARATION AND CHARACTERIZATION OF BOVINE MEAT AND MILK FACTOR VESICLES/PARTICLES & IDENTIFICATION OF MSBI1 REP INTERACTING PROTEINS

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Farhana Manzoor; [2020]
    Nyckelord :Bovine meat and milk factors; multiple sclerosis; immunoprecipitation co-immunoprecipitation; protein dimers; mass spectrometry; immunodetection; cesium chloride density gradient centrifugation; sodium dodecyl sulfate-polyacrylamide gel electrophoresis; vesicle; particle; interaction partner; pull-down assay.;

    Sammanfattning : Introduction: Bovine meat and milk factors (BMMF) frequently isolated from bovine meat and milk, are discussed as putative causative agents for breast, colon and possibly other cancers. The hypothesis was formulated based on earlier correlative studies indicating that BMMFs could indirectly trigger inflammation, accumulate mutational events via reactive oxygen and nitrogen species production which eventually provokes tumor formation.

  3. 12. Utvärdering av ANA-buljong som odlingsmedium : för odling av aeroba och anaeroba bakterier vid inkubering i aerob miljö

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Malin Larsson; [2020]
    Nyckelord :ANA-buljong; Anaerob; Aerob; Bakterier; MALDI-TOF MS;

    Sammanfattning : ANA-buljongen är utvecklad för att kunna anrika både aeroba och anaeroba bakterier vid inkubering i aerob miljö. Odlingsbuljongen innehåller antioxidanter som skyddar anaeroberna mot reaktiva syreradikaler, vilket främjar anaerob anrikning. LÄS MER

  4. 13. Nox inhibitors : A potential future medicine for ischemia stroke

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för hälsa och lärande

    Författare :Charlotte Jackson; [2018]
    Nyckelord :NOX inhibitors; reactive oxygen species; ROS; ischemia stroke;

    Sammanfattning : This study investigated the neuroprotective effects of novel small molecule NOX inhibitors after induction of an ischemic stroke model on Neuroblastoma cells (NB69). Previous findings show that high levels of reactive oxygen species (ROS) have been identified for playing a role in causing inflammation, cellular damage and apoptosis in many cardiovascular diseases.

  5. 14. CRISPR/Cas9 gene-editing in an in vitro model of a familial form of ALS

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Författare :Fredrik Nilsson; [2018]
    Nyckelord :ALS; SOD1; Amyotrophic lateral sclerosis; superoxide dismutase; CRISPR Cas9; sgRNA; stem cell; lentivirus; qPCR; FOXG1; nestin; immunocytochemistry; differentiation; forebrain neural progenitor; Applied Biochemistry; Biology and Life Sciences;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a neuromuscular disease characterized by the degeneration and death of both upper and lower motor neurons for which there is no cure currently available. The degeneration of motor neurons leads to the inability to carry out voluntary movement and death usually occurs 3-5 years after disease onset by respiratory failure. LÄS MER

  7. 15. The effect of the natural antioxidants catalase and epigallocatechin added after thawing on the quality of dromedary camel spermatozoa

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Johanna Grundin; [2018]
    Nyckelord :Camel semen; cryopreservation; antioxidants; reactive oxygen species; sperm quality analysis;

    Sammanfattning : The objective of this study was to evaluate the effect of adding two natural antioxidants (Catalase and Epigallocatechin) to the thawing media on the quality of cryopreserved dromedary camel spermatozoa post-thaw. Also, an indirect measure of ROS production was performed by measuring malondialdehyde (MDA) production (a product of oxidative damage) post-thaw. LÄS MER
