  1. 1. Comparing chemical biodegradation assessed in water-sediment suspensions

    University essay from Stockholms universitet/Institutionen för miljövetenskap

    Author : Kangli Lin; [2023]
    Keywords : water- sediment suspensions; OECD 309; biodegradation; sediment concentrations; bacterial cell count;

    Abstract : Many chemicals are released into surface water and biodegradation is one important mechanismto remove the contaminants. Their actual concentrations in water depend on their persistence.The OECD 309 test is the most recognized method to assess the persistence of chemicals in theaquatic environment. READ MORE

  3. 2. Hypoxia and hematopoietic stem cell control with the substance Adaptaquin : An evaluation of hematopoietic stem cell’s proliferation and differentiation in artificially induced hypoxia

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Jens Christiansen; [2023]
    Keywords : Adaptaquin; Flow cytometry; Hematopoietic stem cells; Hypoxia; Hypoxia inducible factor; Prolyl hydroxylase; Adaptaquin; Flödescytometri; Hematopoetiska stamceller; Hypoxi; Hypoxi inducerande faktor; Prolylhydroxylas;

    Abstract : Hematopoietic stem cells (HSCs) have historically been difficult to maintain ex vivo with many attempts to culture them in vitro by mimicking their natural biological environment. Providing a hypoxic environment is one way to achieve this goal and can be performed by using hypoxia stimulating compounds that inhibits the degradation of HIF1a which plays an important role in regulating hypoxia.

  4. 3. Evaluation of the platelet yield index on interim platelet units from Reveos by comparison with platelet count from Sysmex

    University essay from

    Author : Jennifer Ahlin; [2023]
    Keywords : fluorescent flow cytometry; transfusion; blood component; automation; blood processing system;

    Abstract : Background: Platelets are the smallest cells in the blood and are involved in the wound healing process. Platelet transfusion is an important part of treating illnesses such as thrombocytopenia and to prevent and stop major bleedings. READ MORE

  5. 4. Characterization of bovine milk from indigenous species from Sri Lanka

    University essay from SLU/Department of Molecular Sciences

    Author : Jonathan Skager; [2022]
    Keywords : Milk; total proteolysis; protein profile; capillary electrophoresis; fluorescence; indigenous cattle; Jersey cattle; Friesian cattle; Sri Lanka;

    Abstract : Sri Lanka is a country in south Asia that from the beginning of the 21st century, until 2016 almost doubled their quantity in milk import, this to meet their national market demand for dairy products. The country is divided into different agroecological zones, which are the up-country, mid-country, and the lowlands. READ MORE

  6. 5. Avian Malaria infection and its effect on cellular metabolic rate in Ficedula Flycatchers

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Author : Nader Ibrahim; [2022]
    Keywords : ;

    Abstract : Chronic avian malaria and low-intensity parasite infections can have a negative influence on reproduction and survival which can reduce the fitness of the host. Therefore, the effect on host due to avian malaria infection can affect a bird’s lifespan. Consequently, avian parasites can influence evolution, physiology, and host morphology. READ MORE
