  1. 1. Ovary spheroid formation and quality assessment using two different protocols

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Nikki Wallius Hiltunen; [2023]
    Nyckelord :ovary; fertility; spheroid; Biosilk™; three-layer gradient system; äggstock; fertilitet; sfäroid; Biosilk™; trelagers gradientsystem;

    Sammanfattning : Redan innan födseln fastställs kvinnors fertilitet, som karakteriseras av ett begränsat antal äggblåsor, så kallade folliklar. Beståndet av folliklar minskar naturligt med åldern, samtidigt som kvinnors fertilitet beror på deras steroid- och äggproduktion. LÄS MER

  3. 2. Baggalútar from Hvalfjörður (Iceland): Enigmatic spheroids of hydrothermally altered basaltic tephra

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Sammanfattning : Baggalútar are well-rounded spheroids that typically measures 16-18 mm in size and have a brownreddish appearance. They can be found in the Hvalfjörður bay in SW Iceland. LÄS MER

  4. 3. Development of Microfluidic 3D Cell Culture with a Nanocellulose-Based Scaffold for Spheroid Formation as a Potential Tool for Drug Screening

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Payande; [2022]
    Nyckelord :3D cell culture; Scaffold; Microfluidics; Layer-by-Layer; Cellulose Nanofibrils; Spheroids; HepG2; 3D cellodling; Matris; Mikrofluidik; Layer-by-Layer; Cellulosa Nanofibriller; Sfäroider; HepG2;

    Sammanfattning : Abstract  Lack of clinical relevance is assumed to be the main reason behind the high failure rate of medical drugs in the very initial phases of clinical trials. Clinical relevance is difficult to achieve with current tools as they lack the biological and physiological cues found in vivo. LÄS MER

  5. 4. Knockout studies of Panc1 cells

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Martin Sundin; [2021]
    Nyckelord :PDAC; crosstalk; stroma; spheroid; western blot; viability; gemcitabine.; PDAC;  verh rning; stroma; sf roid; western blot; viabilitet; gemcitabine.;

    Sammanfattning : Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal form of cancerwith very few available treatment options of which none has great effect.Cancer cells and stromal cells such as stellate cells which exist in abundancein PDAC interact by crosstalk, resulting in a tumorigenic collective response.

  7. 5. Fast Simulations of Star Cluster Evolution

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Lina Warntoft; [2019]
    Nyckelord :star cluster simulation numerical method; Physics and Astronomy;

    Sammanfattning : The evolution of globular star clusters tells the history of the formation of galaxies, how stellar streams might have formed and how the future of the Universe might look like. Although the general theoretical background of the evolution is well understood, it is difficult to conduct accurate and realistic computer simulations of objects containing thousands of interacting bodies.
