    Sammanfattning : Many cyanobacteria are reported to produce the nonprotein amino acid β-N-methylamino-L-alanine (BMAA). Cyanobacteria are extensively distributed in terrestrial and aquatic environments and recently BMAA was detected in temperate aquatic ecosystems, e.g. the Baltic Sea. LÄS MER

  4. 18. Mitochondrial involvement in cell death : release of pro-apoptotic proteins

    Författare :Erik Norberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In addition to the role of the mitochondria in energy metabolism, these organelles play a key role in cell death signaling. In particular, mitochondrial alterations, such as stimulation of reactive oxygen species (ROS) formation, decreased ATP synthesis, loss of membrane potential and the release of pro-apoptotic proteins from the mitochondrial intermembrane space (IMS), have been shown to be involved in, and often responsible for, various manifestations of cell death.

  7. 20. Assessing the reliability of detrital zircon in Early-Earth provenance studies

    Författare :Ross Kielman; Martin Whitehouse; Alexander Nemchin; Victoria Pease; Marlina Elburg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geology; geologi;

    Sammanfattning : Our understanding of the Early Earth and the processes that have shaped its evolution have spawned predominantly from the geochemical and isotopic signatures of a small number of zircon populations around the world. Studies of trace element distributions, Hf and O isotope systematics as well as mineral inclusion chemistry in detrital zircon are combined with U-Pb chronology in order to constrain source rock characteristics.
