  2. 1. Cytoplasmic mRNP particles in dormant and developing artemia embryos

    Author : Mats Lake; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In dormant cryptobiotic embryos of Artemia there is a stored pool of messenger RNA (mRNA) associated with the endoplasmic reticulum. Upon resumption of the embryos this latent mRNA is activated and used in the protein synthesis. READ MORE

  4. 2. Morphological and chemical leaf traits of tropical montane tree species and their responses to warming

    Author : Manishimwe Aloysie; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tropical montane forests; tropical trees; leaf morphology; leaf nutrients; warming climate; climate change;

    Abstract : Leaf morphological and chemical traits of tropical trees vary along climate gradients, but it is currently unclear how they will respond to a rapidly warming climate and how this will vary among species. Considering this, tropical trees native to East and Central Africa were investigated in three complementary studies in Rwanda. READ MORE

  5. 3. Transient State Fluorescence Microscopy - method development and biological applications : Exploiting the dark states of fluorophores to measure oxygen concentrations, redox state, Förster resonance energy transfer and membrane viscosity

    Author : Thiemo Spielmann; Jerker Widengren; Karsten König; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transient States imaging TRAST ; Triplet State imaging; fluorescence microscopy; modulated excitation; triplet state; radical state; trans-cis isomerisation;

    Abstract : Due to their long lifetime, triplet, redox and other transient states of fluorophores are highly sensitive to the micro-environment. Imaging their spatial distribution in biological samples can therefore help answer interesting questions about the metabolism, molecular interactions and dynamics in living cells. READ MORE

  6. 4. High-resolution imaging of kidney tissue samples

    Author : David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biological Physics; Biologisk fysik;

    Abstract : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  7. 5. Species interactions in streams - effects of predation, competition and ecosystem properties

    Author : Erika Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; behaviour; species abundance; stable isotopes; habitat complexity; niche width; niche overlap; competition; streams; predation;

    Abstract : Stream ecosystems are dynamic and they have an inherent environmental variability. Organisms that live in streams are adapted to the continuously changing environment and the presence or absence of species are determined by their environmental requirements, while abundance is most often affected by interactions, such as competition and predation, with other species that are found in the same habitat.
