  1. 1. Protection of Photosystem II from Photodamage during the Assembly of the Water Oxidizing Complex

    Author : Maria Rova; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TyrosineD; cytochrome b559; Photoinhibition; Photoactivation; Botany; Botanik;

    Abstract : Photosystem II catalyses the light driven oxidation of water, which is a key reaction in oxygenic photosynthesis. This enzyme is, however, exposed to light induced degradation, which decreases the efficiency of the photosynthetic process. READ MORE

  2. 2. Exploiting chemical control in biomaterials

    Author : Tove Kivijärvi; Anna Finne Wistrand; Barner-Kowollik Christopher; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomaterial; controllable chemistry; polyester; ring-opening polymerization; hyaluronan; degradation; photoactivation; protein release; cell differentiation; biomaterial; kontrollerbar kemi; polyester; ring-öppnings polymerisering; hyaluronsyra; nedbrytning; fotoaktivering; frigöring av protein; celldifferentiering; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Chemistry and biology at the interphase will most likely give many of the answers to tomorrows medical challenges. Creating solutions to the problems at this interphase is benefiting from a collaborative research approach, driven by the need for development of chemistries or devices solving medical problems.

  4. 4. Paracrine control of glucagon secretion in the pancreatic α-cell: Studies involving optogenetic cell activation

    Author : Caroline Miranda; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Glucagon; α-Cell; Optogenetics;

    Abstract : ABSTRACT The mechanisms controlling glucagon secretion by α-cells in islets of Langerhans were studied. We generated mice with the light-activated ion channel ChR2 specifically expressed in β-, α-, and δ-cells, and explored the spatio-temporal relationship between cell activation and glucagon release.

  5. 5. Terahertz radiation as a pump and probe for studying low frequency vibrations in proteins

    Author : Ida Lundholm; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terahertz radiation; Protein dynamics;

    Abstract : Many functionally important structural changes in proteins proceed along the direction of their lowest frequency vibrations. These vibrations correspond to picosecond collective dynamics. Establishing the fundamental relationship between these vibrations and protein function remains a challenge within biophysics. READ MORE
