  2. 21. Steady-State Diffusion in Complex Amphiphilic Films

    Author : Christoffer Åberg; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; film formation; lung surfactant; skin surface pH; stratum corneum; responding membrane; diffusive transport; phase transition;

    Abstract : The relation between structure and diffusive transport at steady-state is investigated theoretically for amphiphilic systems. Amphiphilic systems typically show a large response to moderate changes in control parameters, such as temperature, osmotic pressure, and the presence of cosolvents and cosolutes. READ MORE

  4. 22. Ion homeostasis in control of stem cell proliferation

    Author : Shaimaa Abdelhady; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The ion homeostasis is critically maintained in all cells by a combined effort from various ion channels, transporters, pumps, and gap junctions. Ion fluxes are essential in excitable cells as they regulate the excitability of the cells and initiate and propagate action potentials. READ MORE

  5. 23. Cardiopulmonary bypass: Clinical studies in cardiac surgery patients

    Author : Mikael Barbu; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; Cardiac surgery; Colloid; Prime; Acute kidney injury; Brain injury marker; Hemostasis;

    Abstract : BACKGROUND: Cardiopulmonary bypass (CPB) is necessary to facilitate most cardiac operations. Although the vast majority of patients tolerate CPB physiology in conjunction with cardiac surgery well, there is risks of adverse outcomes. Optimal CPB perfusion is not defined, and may vary according to operation and patient specific factors. READ MORE

  6. 24. Integrative analysis of osmoregulation in yeast Saccharomyces cerevisiae

    Author : Roja Babazadeh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Similar to other unicellular organisms, yeasts frequently encounter environmental stress such as heat shock, osmotic stress, and nutrition limitations, which challenge their growth potential. To survive, all living cells must be able to adapt to changes in their surrounding environment. READ MORE

  7. 25. Towards Energy-Efficient Drinking Water Production using Biomimicry

    Author : Simon Isaksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filter; Membrane Protein; Supported Lipid Bilayer; Drinking Water; Water Treatment; Silica; Aquaporin; Liposome; Biomimicry;

    Abstract : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. READ MORE
