  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  3. 2. Minskar blåljus-filtrerande intraokulära linser risken att utveckla åldersrelaterad makuladegeneration (AMD)?

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för medicin och optometri (MEO)

    Författare :Jasmine Taoube; Hanna Sayadi; [2023]
    Nyckelord :Blåljus-filtrerande intraokulära linser BLF-IOL ; åldersrelaterad makuladegeneration AMD ;

    Sammanfattning : Background: Age-related macular degeneration (AMD) is a leading cause of visualimpairment in the world. AMD is a retinal degenerative condition that affects themacular area of the retina and thus the central vision. LÄS MER

  4. 3. Evaluation of antioxidant effect of an algae extract on skin: in vitro study

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Oday Al Mustafa; [2023]
    Nyckelord :Algae extract; antioxidant; DPPH; microalgae; ROS; skin covered oxygen electrode; skin;

    Sammanfattning : Algae extracts are used as cosmetic products and used as additives in specific foods because of their antioxidant activity. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radicals are toxic on the skin and can be scavenged by antioxidants, which are abundant in microalgae. LÄS MER

  5. 4. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Monica Olsson; [2022-10-05]
    Nyckelord :Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Sammanfattning : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. LÄS MER

  7. 5. Factors and mechanisms associating the mobilisation of Ca2+ with the activation of the NLRP3 inflammasome : A systematic review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Maria Panagiota Theodorou; [2022]
    Nyckelord :;

    Sammanfattning : Inflammasomes are multiprotein complexes that play a critical role in the regulation of inflammation and the inflammatory responses against pathogens. NLRP3 (NOD-, LRR-and pyrin domain-containing protein 3) is among the molecules involved in the homonymous and well-studied NLRP3 inflammasome that accounts for the release of the pro-inflammatory cytokines interleukin (IL) 1-β and 18.
