  1. 21. Quantum Coherence for Light Harvesting

    Författare :David Palecek; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Sammanfattning : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. LÄS MER

  3. 22. Role of water channels in kidney and lung

    Författare :Yanhong Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aquaporins (AQPs) are membrane proteins that function as water channels facilitating a rapid and regulated transport of water across cell membranes. AQPs in kidney and lung play pivotal roles for the regulation of water homeostasis. LÄS MER

  4. 23. Nephroprotective effect of the cardiotonic steroid ouabain

    Författare :Ievgeniia Burlaka; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : It has been shown that Na,K-ATPase (NKA) is a signal transducer. Our group described the anti-apoptotic effect of ouabain to the signaling function of NKA. LÄS MER

  5. 24. Renal cell death in urinary tract infections : role of E. coli toxins

    Författare :Ming Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Pyelonephritis; Escherichia coli toxins; ERK; LPA; cell death; carbon monoxide; hemolysin; nitric oxide; heme oxygenase-1; dexamethasone; kidney development;

    Sammanfattning : Febrile urinary tract infections (UTI) are common bacterial illnesses in children. Several follow up studies have shown that 10-15 % of infants with pyelonephritis will develop permanent renal damage, i.e., renal scars, which in turn may lead to chronic diseases such as hypertension and renal insufficiency.

  7. 25. Visualizing the dynamic interplay between the host and bacterial pathogen : a real-time study of renal infection

    Författare :Lisa Månsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human body is a complex entity capable of handling a variety of pathogenic challenges without developing disease symptoms. Sometimes, however, the pathogens are superior and the host immune system is unable to clear the infection. LÄS MER
