  2. 1. Structural and functional studies of protein complexes involved in energy metabolism

    Author : Jens Berndtsson; Martin Ott; Irene Diaz-Moreno; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mitochondria; metabolism; OXPHOS; yeast respiratory supercomplex; cytochrome c; coenzyme Q; pyruvate dehydrogenase complex; Biochemistry; biokemi;

    Abstract : Mitochondria are eukaryotic organelles with a multitude of functions including biosynthesis of molecules and cellular regulation. Most prominently though is their role in energy conversion which culminates with the production of ATP, the universal molecular unit of currency. READ MORE

  4. 2. Energy-Related Metabolites during and after Induced Myocardial Ischemia and Retroperfusion of the Coronary Sinus : An Experimental Study in the Pig with the Microdialysis Technique and Extracorporeal Circulation

    Author : Vitas Zemgulis; Rolf Ekroth; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischemia; myocardial infarction; reperfusion; energy metabolism; coronary sinus retroperfusion; microdialysis; taurine; nucleoside transport; adenosine; aerobic lactate production; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Abstract : In the clinical setting great efforts have been made with contradictory results to operate upon acutely myocardial ischemic patients. The reasons for the absence of unambiguous results are not well understood nor are they scientifically explored. READ MORE

  5. 3. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

    Author : Karin Willquist; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

    Abstract : A high substrate conversion efficiency is a prerequisite for an economically feasible biohydrogen production. Caldicellulosiruptor saccharolyticus is a strictly anaerobic extreme thermophilic bacterium that is able to convert the theoretical maximum of 4 mol/mol glucose to H2. READ MORE

  6. 4. Fast and reliable alignment and classification of biological macromolecules in electron microscopy images

    Author : Björn Forsberg; Erik Lindahl; Sriram Subramaniam; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryo-EM; electron microscopy; GPU; parallel processing; protein structure; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Abstract : In the last century, immense progress has been made to charter and understand a wide range of biological phenomena. The origin of genetic inheritance was determined, showing that DNA holds genes that determine the architecture of proteins, utilized by the cell for most functions. READ MORE

  7. 5. Mitochondrial DNA mutations : brain developmental and ageing consequences, and possible treatments

    Author : Jaime M Ross; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Ageing is a complex process that involves cellular senescence, a gradual loss of tissue homeostasis, and decline in organ function. Abundant evidence implicates mitochondria in ageing suggesting: (i) accumulation of mitochondrial DNA (mtDNA) damage, (ii) progressive respiratory chain dysfunction, and (iii) increased reactive oxygen species production.
