  1. 21. 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

  3. 22. Alpha 1-antitrypsin: A Role in Cancer Progression

    Författare :Inga Zelvyté; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; onkologi; Cytologi; cancerology; oncology; Cytology; invasion; neutrophils; cancer cell; Alpha1- antitrypsin; proteinase inhibitors;

    Sammanfattning : Alpha1-antitrypsin (AAT), a circulating single-chain glycoprotein is the most abundant serine proteinase inhibitor in human plasma. AAT is an acute phase protein, its levels increase rapidly to concentrations exceeding 50mM in response to inflammation, infection and malignant diseases. LÄS MER

  5. 24. The Invasion of the Zebra Mussel - Effects on Phytoplankton Community Structure and Ecosystem Function

    Författare :Rahmat Naddafi; Kurt Pettersson; Peter Eklöv; Willem Goedkoop; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Invasive species; Zebra mussel; Invasion success; Selective feeding; Non-lethal effects of predator; Seston stoichiometry; Delayed fluorescence excitation spectroscopy; Phytoplankton dynamics; Trait-mediated indirect interaction; Ecosystem function;

    Sammanfattning : Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. LÄS MER

  7. 25. A Phytoplankton Invasion: Population Genetics, Phylogeography, and Invasion Success of Gonyostomum semen

    Författare :Karen Lebret; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : nvasive species is a major threat to ecosystems and biodiversity. Invasions by macroorganisms have been intensively studied, but little is known concerning microbial invasions. In aquatic environments, phytoplankton, i.e. LÄS MER
