  1. 1. The type I-E CRISPR-Cas system : Biology and applications of an adaptive immune system in bacteria

    Author : Lina Amlinger; Magnus Lundgren; Peter Fineran; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; CRISPR; CRISPR-Cas; virus defense; bacteria; bacteriophage; adaptation; spacer integration; interference; gene silencing; fluorescent reporter; Escherichia coli; Mikrobiologi; Microbiology;

    Abstract : CRISPR-Cas systems are adaptive immune systems in bacteria and archaea, consisting of a clustered regularly interspaced short palindromic repeats (CRISPR) array and CRISPR associated (Cas) proteins. In this work, the type I-E CRISPR-Cas system of Escherichia coli was studied.CRISPR-Cas immunity is divided into three stages. READ MORE

  2. 2. Sulfur Capture and Oxidation of Calcium Sulfide in PFBC

    Author : Kuanrong Qiu; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxidation; model; pressure; sulfur; PFBC; CaS; limestone; CaSO4; PTGA; regeneration;

    Abstract : Sorbents such as limestone are successfully used for removal of SO2 during pressurized fluidized bed combustion (PFBC) processes. However, there still remains a strong incentive to reduce the consumption of such sorbents. READ MORE

  3. 3. Parameters influencing inclusion compositions in Al-killed steel melts during a secondary refining process

    Author : Takanori Yoshioka; Andrey Karasev; Pär Jönsson; Joohyun Park; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-metallic inclusion; ladle furnace; RH; thermodynamics; contact angle; Al2O3; MgO•Al2O3 spinel; calcium aluminate; CaS.;

    Abstract :      This study was carried out to clarify the factors influencing the evolution of inclusions in Al-killed steel melts during a secondary refining process. First, a case-hardening steel was the subject of study to understand the factors influencing the inclusion compositions in the steel melt. READ MORE

  4. 4. Antiphagocytosis by Yersinia pseudotuberculosis : role of the YopH target proteins

    Author : Ming Yuan; Maria Fallman; Tommy Nilsson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular biology; Cas; Fyb; mAbp1; SKAP-HOM; Yersinia pseudotuberculosis; YopH; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The enteropathogenic bacterium Yersinia pseudotuberculosis binds to β1 integrins on a host cell via its surface protein invasin. This event stimulates signal transduction to the actin cytoskeleton of the eukaryotic cell, which allows the cell to engulf the bacterium that is attached to its surface. However, the pathogen Y.

  5. 5. Studies on the transmembrane signaling of β1 integrins

    Author : Annika Armulik; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin β1; signaling; transmembrane domain; CAS; focal adhesion kinase; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Abstract : Integrins are heterodimeric cell surface receptors, composed of an α and a β subunit, mainly binding for extracellular matrix proteins. lntegrin subunit β1 can combine with at least 12 a subunits and thus form the biggest subfamily within the integrin family. READ MORE
