  1. 16. Modeling glioblastoma growth patterns and their mechanistic origins

    Författare :Emil Rosén; Sven Nelander; Rebecka Jörnsten; Philip Gerlee; Kristin Swanson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; glioblastoma; invasion; image analysis; neural networks; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik; Oncology; Onkologi; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Glioblastoma (GBM) is the most common and aggressive primary brain cancer. GBM cells migrate away from the primary lesion and invade healthy brain tissue. The invading cells escape surgical resection, radiotherapy and develop resistance to chemotherapy. Consequently, despite treatment, recurrence is inevitable, and survival is only 14 months. LÄS MER

  3. 17. Cyclin E overexpression and associated events in human breast cancer

    Författare :Maria Stighall; Malmö Patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; patologisk anatomi; Patologi allmän ; pathological anatomy; General pathology; tumour growth pattern; invasion; proliferation; ID2; cyclin E; pRb; cell cycle; breast cancer;

    Sammanfattning : Unrestrained proliferation is a hallmark of cancer and genetic defects within G1/S-phase regulation and the pRb pathway occur frequently. Proliferation control can be circumvented either by excess cyclin D1 or cyclin E, alterations that can define two alternative tumour biologic pathways in breast cancer. LÄS MER

  4. 18. Round goby invasion of the Baltic Sea : the role of phenotypic variation

    Författare :Magnus Thorlacius; Tomas Brodin; Göran Englund; Jost Borcherding; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Round goby Neogobius melanostomus ; behaviour; animal personality; dispersal; species invasions; colonisation; spread; sociability; activity; boldness; aggression; cortisol coping-styles; biology; biologi;

    Sammanfattning : Biological invasions are a major threat to biodiversity world wide with annual economic costs up to 1.4 trillion dollars. The round goby (Neogobius melanostomus) is a particularly fierce invader that threatens ecological function of the Baltic Sea. LÄS MER

  5. 19. Glycosylation in cancer and infection : the role of sialic acid

    Författare :Yuecheng Zhang; Anette Wingren; Maria Stollenwerk; Lars Ohlsson; Martin Dufva; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer; sialic acids; receptor; molecularly imprinted polymers; SARS-CoV-2; fluorescence; Health and society; Hälsa och samhälle;

    Sammanfattning : Sialic acids (SA), a group of nine-carbon backbone monosaccharides are abundantly expressed in vertebrates. They are usually linked to the terminal of glycan chains and play crucial roles in many biological processes, including cell adhesion, cell-cell interactions, immune modulation, cancer cell migration and invasion, as well as viral infections.

  7. 20. Intra-specific variation in avian malaria : Linking infection dynamics to haplotypes

    Författare :Victor Kalbskopf; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; avian malaria; phyogenetics; population genetics; evolution;

    Sammanfattning : Avian Malaria infects thousands of species of birds across the Aves class. The most widespread (geographically and phylogenetically)morphological species is Plasmodium relictum, and of that, the mitochondrial lineage of SGS1 is the most common and invasive. LÄS MER
