1. Advances in DNA Detection
Sammanfattning : DNA detection technologies have an increasing importance in our everyday lives, with applications ranging from microbial diagnostics to forensic analysis, food safety evaluation, and environmental monitoring. Currently, as the associated costs decrease, DNA diagnostic techniques are routinely used in research laboratories, in clinical and forensic practice. LÄS MER
2. Electric DNA arrays for determination of pathogenic Bacillus cereus
Sammanfattning : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. LÄS MER
3. Electric DNA chips for determination of pathogenic microorganisms
Sammanfattning : Silicon-based electric DNA chip arrays were utilized to fast identify pathogenic microorganisms with respect to the capacity to produce toxins involved in foodborne poisoning and infections. Bacteria of the B. cereus and the enterohemorrhagic E. LÄS MER
4. An X-ray Based Spectroscopic Study of Structure Influencing Electrons : Fragmentation, Ultrafast Charge Dynamics and Surface Composition
Sammanfattning : The structure of biomolecules, such as proteins, is intimately connected to the function of the molecules. These structures are often studied using X-ray diffraction. However, the interaction of the X-ray photons with the molecule can excite or ionize its electrons which in turn can causes changes in the molecular structure. LÄS MER
5. Oxidative damage and the DNA glycosylase MutYH
Sammanfattning : The DNA glycosylase MutYH is highly conserved throughout evolution, and homologs are found in most eukaryotes and prokaryotes examined. MutYH functions as a base excision repair DNA glycosylase that excises adenines misincorporated opposite 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG), one of the most stable products of oxidative DNA damage.
