  1. 6. GSK-3 and ROS (reactive oxygen species) inhibition modulate Vimentin expression

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Ragad Hassano; [2022]
    Nyckelord :;

    Sammanfattning : When exposed to pathogenic stress, cellular processes and survival are dependent on cytoskeletal proteins for structure and organisation of the cell to adapt and maintain homeostasis during inflammation. Vimentin is type III cytoskeletal protein, with an extensive cytoplasmic meshwork, across the cell and regulate the cell structure and cellular space and expressed strongly under tumorigenic events.

  3. 7. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Lea Enenkelová; [2021]
    Nyckelord :sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

    Sammanfattning : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

  4. 8. Metformins potential att fördröja mänskligt åldrande

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Lotta Wiberg; [2021]
    Nyckelord :metformin; åldrande; livslängd; biologi;

    Sammanfattning : Humans have never before lived as long and we have never had as many cures and treatments for diseases as now. But we still spend the last years of our lives sick with age-related diseases. Some scientists say it is time to grasp the problem by its roots – which in this case is aging itself. LÄS MER

  5. 9. Oxytocin, en endogen neuropeptid med potential att minska mortaliteten vid sepsis? : En litteraturstudie

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

    Författare :Evelina Gustafsson; [2021]
    Nyckelord :sepsis; oxytocin; organdysfunktion;

    Sammanfattning : Sepsis is a relatively unknown, but common, condition with high mortality. Sepsis is defined as life-threatening organ dysfunction caused by an excessive immune response in the host as a result of an infection. Sepsis can be caused by many different pathogens, giving a varying symptomatic profile and arise via many different routes of exposure. LÄS MER

  7. 10. Environmental transformations of Manganese and Manganese oxide nanoparticles

    Master-uppsats, KTH/Materialvetenskap

    Författare :Lundberg Annie; [2020]
    Nyckelord :;

    Sammanfattning : Engineered nanoparticles (NPs) are produced in increased quantities. Due to this increase, itis vital to understand the full lifecycle and fate of these NPs to prevent any possible environmental stress. LÄS MER
