  2. 1. Reaction dynamics on highly excited states

    Author : Johanna Brinne Roos; Åsa Larson; Ioan F. Schneider; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio calculations; dissociative recombination; resonant ion-pair formation; mutual neutralization; molecular electronic states; molecule-electron collisions; quantum chemistry; molecular dynamics; Chemical physics; Kemisk fysik; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Abstract : In this thesis I have performed theoretical studies on the reaction dynamics in few-atom molecules. In particular, I have looked at reaction processes in which highly excited resonant states are involved. READ MORE

  4. 2. The Oxygen Evolving cycle in Photosystem II studied with EPR Spectroscopy at different pH and Temperature

    Author : Susan F Morvaridi; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Naturvetenskap; Temperature; Natural science; pH; EPR; S cycle; Photosystem II;

    Abstract : PSII catalyses the light-induced water splitting process which leads to electron transfer through the thylakoid membrane and formation of energy rich molecules. Several redox components including a Mn4Ca, an amino acid residueYZ, two special Chl molecules P680, two Pheo and two quinone molecules participate in this process. READ MORE

  5. 3. Protonmotive coupling of energy conversion processes in photosyntetic bacteria : studies on membrane energization and photophosphorylation capacity

    Author : Beston F. Nore; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fotosyntes;

    Abstract : This work is a study on the membrane-bound inorganic pyrophosphatase and other energylinkedenzymes in the chromatophores from the photosynthetic bacterium Rhodospirillum rubrum.The membrane-bound inorganic pyrophosphatase is functionally similar to the well-known FiF0-ATP synthase.

  6. 4. Elucidating the molecular basis of Na+/H+ exchange

    Author : Pascal F. Meier; David Drew; Simon Newstead; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane protein; secondary-active transporter; Solute Carrier Transporter; ion-exchange; sodium proton exchanger; potassium proton exchanger; protein structure; cryo-EM; regulation; biokemi; Biochemistry;

    Abstract : Solute carrier (SLC) transporters are membrane transport proteins, which catalyse the movement of nutrients, ions, and drugs across cell membranes. Here, I will present our contribution to understanding the mechanism of the sodium/proton exchangers (NHE), belonging to the SLC9 family of membrane transporters. READ MORE

  7. 5. Pathophysiology of subarachnoid hemorrhage in the rat

    Author : Giselle F Prunell dos Santos; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Apoptosis; cell death; cerebral blood flow; cerebral metabolism; inflammation; NMDA receptor subunits; subarachnoid hemorrhage.;

    Abstract : Subarachnoid hemorrhage (SAH) causes brain damage, but the underlying mechanisms are poorly understood. An obstacle in SAH research is the lack of an adequate animal model. In this thesis, we developed a new approach to simulate SAH that involves the injection of blood into the prechiasmatic cistern of the rat. READ MORE
