Notes

In order to gain an overview of the available genotypic and phenotypic methods used for pathogen typing of Salmonella and Shiga toxin-producing and enterohemorrhagic Escherichia coli (STEC/EHEC) in Germany at state and federal level, along with the availability of WGS-based typing and corresponding analytical methods, a survey of laboratories was conducted
METHODS: An electronic survey of laboratories working for public health protection and consumer health protection was conducted from February to June RESULTS AND CONCLUSION: The results of the survey showed that many of the participating laboratories provide a wide range of phenotypic and molecular methods. Molecular typing is most commonly used for species identification of Salmonella. In many cases, WGS-based methods have already been established at federal and state institutions or are in the process of being established. The Illumina sequencing technology is the most widely used technology. The survey confirms the importance of molecular biology and whole genome typing technologies for laboratories in the diagnosis of bacterial Referenzzentrum (NRZ) für Salmonellen und andere bakterielle Enteritiserreger, Robert Koch-Institut (RKI), Burgstr. 37, 38855, Wernigerode, Deutschland.

In this work, the micro-arc oxidation method is used to fabricate surface-modified complex-structured titanium implant coatings to improve biocompatibility. Depending on the utilized electrolyte solution and micro-arc oxidation process parameters, three different types of coatings (one of them-oxide, another two-calcium phosphates) were obtained, differing in their coating thickness, crystallite phase composition and, thus, with a significantly different biocompatibility. An analytical approach based on X-ray computed tomography utilizing software-aided coating recognition is employed in this work to reveal their structural uniformity. Electrochemical studies prove that the coatings exhibit varying levels of corrosion protection.

In vitro and in vivo experiments of the three different micro-arc oxidation coatings prove high biocompatibility towards adult stem cells (investigation of cell adhesion, proliferation and osteogenic differentiation), as well as in vivo biocompatibility (including histological analysis). These results demonstrate superior biological properties compared to unmodified titanium surfaces. Polysucrose 400 Sweetener of calcium and phosphorus in coatings, as well as their phase composition, have a great influence on the biological response of the coatings. CCAAT/enhancer binding protein α (C/EBPα) is the key transcription factor involved in lipid metabolism, however, the role of C/EBPα in milk fat synthesis of dairy goats remains unknown. The objective of the present research was to clarify the function of C/EBPα in goat mammary epithelial cells (GMECs) and its impact on peroxisome proliferator-activated receptor gamma (PPARG) promoter activity. In this study, C/EBPα overexpression increased its mRNA and protein levels by 42-fold and 6-fold, respectively. In contrast, transfecting siRNA targeting C/EBPα decreased its mRNA level to 20% and protein abundance to 80% of the basal level.

The contents of lipid droplets, triacylglycerol (TAG), and cholesterol were increased (P < 05) in C/EBPα-overexpressing GMECs, and knockdown of C/EBPα led to the opposite results. Overexpression of C/EBPα significantly increased the expression levels of genes involved in TAG synthesis (AGPAT6, DGAT2, P < 01), lipid droplet formation (PLIN2, P < 01), and fatty acid synthesis (FADS2, P < 05; ELOVL6, P < 01). Knockdown of C/EBPα decreased (P < 05) the expression levels of AGPAT6, DGAT1, DGAT2, PLIN2, FADS2, and ELOVL C/EBPα upregulated the expression level of PPARG (P < 05), and four C/EBPα binding regions were identified in the PPARG promoter at -1,112 to -1,102 bp, -734 to -724 bp, -248 to -238 bp, and -119 to -109 bp. Knockdown of C/EBPα were mutated at -1,112 to -1,102 bp, -734 to -724 bp, and -248 to -238 bp locations of the promoter. However, the promoter activity did not change when the mutation was located at -119 bp. In conclusion, our results suggest that C/EBPα can promote TAG synthesis in GMECs through its effects on mRNA abundance of genes related to lipid metabolism and regulation of the PPARG promoter activity via American Society of Animal Science.
