  2. 1. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes

    Author : Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

    Abstract : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

  4. 2. Situating Simulators : The integration of simulations in medical practice

    Author : Ericka Johnson; Boel Berner; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; reconstitution; medical simulators; simulations; situated learning; medical practice; apprenticeship; legitimate peripheral participation; intra-action; agency; medicinsk utbildning; simulering; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This study examined the practices of integrating simulators into medical education. Simulators have been observed in use to discern how medical practices are created out of the simulations. Video recordings of the simulations have been analysed, complemented by interviews with instructors and students. READ MORE

  5. 3. Insight into the mitochondrial apoptotic pathway : The interplay of the pro-apoptotic Bax protein with oxidized phospholipids and its counterplayer, the pro-survival Bcl-2 protein

    Author : Marcus Wallgren; Gerhard Gröbner; Marco Colombini; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; apoptosis; Bax; Bcl-2; CD; cell-free protein synthesis; DSC; membrane; mitochondria; oxidized phospholipids; reconstitution; solid state NMR; biologisk kemi; biological chemistry;

    Abstract : Apoptosis plays a crucial role in multicellular organisms by preserving tissue homeostasis and removing harmful cells. The anti-apoptotic B-cell CLL/lymphoma 2 (Bcl-2) and the pro-apoptotic Bcl-2-associated X protein (Bax) act as major regulators of the mitochondrial apoptotic pathway. READ MORE

  6. 4. The Performative Structure : Ritualizing the pyramid of Pepy I

    Author : Nils Billing; Eva Hellman; Harold Hays; Uppsala universitet; []
    Keywords : Pyramid Texts; monumentality; iconicity; performativity; Pepy I; reconstitution; manifestation; resurrection; ascension; ritual agency; mortuary temple; cult; pyramid; Religionshistoria; History of Religions;

    Abstract : This study investigates the ancient Egyptian pyramid complex as a ritualized structure. In accordance with an indigenous cultural pattern, the category of an eternal architecture had been created at the beginning of the Old Kingdom (ca. 2700 B.C. READ MORE

  7. 5. Assembly and Function of Nitric Oxide Reductase from Paracoccus denitrificans

    Author : Maximilian Kahle; Pia Ädelroth; Hans-Georg Koch; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-heme iron; cofactor; heme-copper oxidase; AAA ; cNOR; chaperone; metal ion insertion; MoxR; nor accessory genes; FeB; liposomes; membrane mimetics; nanodiscs; reconstitution; enzymatic mechanism; NO reduction; O2 reduction; Biochemistry; biokemi;

    Abstract : Bacterial denitrification is a part of the global nitrogen cycle and comprises the stepwise reduction of nitrate to molecular nitrogen, which is released to the atmosphere. Cytochrome c-dependent nitric oxide reductase (cNOR) from Paracoccus (P.) denitrificans catalyzes the reduction of nitric oxide to nitrous oxide and water. READ MORE
