  1. 1. Cellular remodeling in response to nutrient exhaustion : From membrane contact sites to autophagy

    Author : Mahsa Ebrahimi; Sabrina Büttner; Cristina Mazzoni; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Aging and longevity; yeast; phosphate restriction; interorganellar communication; autophagy; MVB pathway; NVJs; lipid droplets; nutritional regimes; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Adaptation to fluctuating environments is critical for cellular fitness and survival. Cells need to sense changes in their surroundings and quickly adjust cellular homeostasis and metabolism accordingly. READ MORE

  2. 2. Studies on the phenotype and function of osteoclasts using osteopetrotic and rachitic animal models

    Author : Karin Hollberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Bone mineralization; bone resorption; osteoclast; tartrate-resistant acid phosphatase; proteolytic processing; cathepsin K; rickets; osteopetrosis; FGF-23;

    Abstract : Osteoclasts are multinucleated bone-resorbing cells that have been implicated in a variety of skeletal diseases e.g. osteoporosis, rheumatoid arthritis and skeletal metastasis. Under physiological conditions, the osteoclast participates in ossification during longitudinal bone growth as well as in bone remodelling during adulthood. READ MORE

  3. 3. DNA Binding of Metal Complexes. A Spectroscopic Study of Trigonal Ru(II)phenanthroline Complexes and Uranyl(VI) Ion with Respect to Specific Interactions with DNA

    Author : Catharina Hiort; Chalmers University of Technology; []
    Keywords : uranyl; nucleic acids; optical probes;

    Abstract : The interaction of metal complexes with nucleic acids has attracted attention owing to their potentials as optical probes, probes of chirality, and for use as artificial restriction enzymes. To understand the underlying mechanisms in these contexts we studied the binding to DNA of the enantiomers of two chiral ruthenium(II) metal complexes ([Ru(phen)3]2+ and [Ru(phen)2]2+DPPZ) phen=1,10-phenanthroline, DPPZ=dipyrido[3,2-a:2',3'-c]phenazine, and of the linear uranium(VI) complex, uranyl ([UO2]2+), using linear dichroism, circular dichroism and luminescence, as well as nuclear magnetic resonance spectroscopy.

  4. 4. On yeasts from traditional fermented foods - Characterization, phytate degradation, strain improvement and applications

    Author : Linnea Qvirist; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytase; Saccharomyces cerevisiae; Phytate; Pichia kudriavzevii; Phenotypic Characterization; Goat Milk; Food Fermentation; Kluyveromyces marxianus; Yaghnob Valley;

    Abstract : Plant materials naturally contain minerals of iron, zinc and calcium. However, plants also contain a compound called phytic acid, which can chelate the minerals and form insoluble complexes. Minerals from plant foods are unavailable for intestinal uptake when they are bound in phytate complexes. READ MORE

  5. 5. Outline of Titanium (IV) based H2PO4 Ion-exchangers: Kinetics and Sorption models

    Author : Mylene Trublet; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Decontamination of industrially polluted waters has been enclosed in REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) since 2007, when it entered into force in the European Union, which emphasized the need to search for more effective sorbents. Many studies on inorganic ion-exchangers have been carried out due to the scientific interest towards their high mechanical and thermal stabilities, high resistance to oxidation and high sorption capacity regarding transition and radioactive metal ions.
