1. The type I-E CRISPR-Cas system : Biology and applications of an adaptive immune system in bacteria
Sammanfattning : 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. LÄS MER
2. Sulfur Capture and Oxidation of Calcium Sulfide in PFBC
Sammanfattning : 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. LÄS MER
3. Parameters influencing inclusion compositions in Al-killed steel melts during a secondary refining process
Sammanfattning : 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. LÄS MER
4. Antiphagocytosis by Yersinia pseudotuberculosis : role of the YopH target proteins
Sammanfattning : 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. Studies on the transmembrane signaling of β1 integrins
Sammanfattning : 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. LÄS MER
