Figure 2 Changes in DXA fat mass (A) and DXA lean mass (B) from days 7 to 30 of daily gavage feeding 1 human equivalent dose (1.1 g/d, ‘low’), 3 human equivalent doses (3.4 g/d, ‘medium’), and 6 human equivalent doses (6.8 g/d, ‘high’) of the WPH-based supplement as well as water only (‘water’). All data are presented as mean ± SE and % changes from day 7 to day 30 are presented above

each bar graph. No between-condition differences were detected. As expected, progressive increases in the average amount of protein consumed per day were present from low to CP673451 cost medium to high dosages (p < 0.05, Figureb OICR-9429 cell line 3A). Interestingly, there was also a significant difference between total energy consumed between WPH-based supplement conditions with the high dose exhibiting a significantly lower amount of food intake relative to the low-dose (p < 0.05, Figureb 3B) and water

only condition (p < 0.01). Figure 3 Average daily protein (‘PRO/d’, A) and kilocalorie (‘kcal/d’, B) intake over the 30-day daily gavage feeding of 1 human equivalent dose (1.1 g/d, ‘low’), 3 human equivalent doses (3.4 g/d, ‘medium’), and 6 human equivalent doses (6.8 g/d, ‘high’) of the WPH-based supplement as well as water only (‘water’). All data are presented AZD2281 cell line as mean ± SE and daily

averages are presented numerically above each bar. As expected, average protein MG-132 in vitro intakes over the 30-day intervention (subfigure A) were as follows: high > medium > low = water (p < 0.01 denoted by different letters above each bar). Interestingly, energy intakes were significantly lower in the high condition relative to the low and water conditions (p-values presented above bars). Liver and kidney histopathology and serum clinical chemistry profiles Histopathological assays conducted on the liver and kidneys after 30 days of low dose, medium dose or high dosages of the WPH-based supplement feeding showed no adverse effects on clinical pathology markers relative to water only feeding (Table 1). Interestingly, the proportion of rats fed water for 30 days (4/5 rats) presented significantly more >21 hepatocellular mitoses counts (representative of potential liver damage) relative to rats in the low (0%), medium (0%) and high WPH-based supplement conditions (0%, X 2 p = 0.001).

Conclusion We have developed a version of the two-plasmid recombineering system for generating chromosomal modifications in E. coli Selleck Barasertib strains which, we have termed Gene Doctoring. This method relies on homologous recombination, mediated by the λ-Red genes, of a linear DNA fragment that is supplied in vivo by restriction of a pDOC donor plasmid by I-SceI endonuclease. The identification

of recombinants is highly efficient and reproducible, since counter-selection

using the sacB gene identifies true recombinants. This eliminates the requirement for screening large numbers of candidates by PCR, which is both costly and buy Ro 61-8048 time consuming. In addition, we have made a modified recombineering plasmid, pACBSCE, which carries a DNA recognition site for I-SceI in the origin of replication, meaning that recombinants are not over-exposed to the potential mutagenic side-effects of the λ-Red gene products. The gene doctoring system is principally effective for recombineering in different pathogenic E. coli strains, Exoribonuclease which as we have demonstrated, are not particularly amenable to chromosomal modification using existing

systems. This system is designed to facilitate the coupling of genes to epitope tags, though the deletion of genes can also be readily achieved. We have demonstrated the versatility of Gene Doctoring by deleting genes in both laboratory and pathogenic E. coli strains, in addition to coupling several genes to epitope tags, and we have confirmed the functionality of epitope tagged fusion proteins using biochemical methods. We believe that the gene doctoring system can be transferable to other bacteria, in which the pDOC and pACBSCE plasmids are stable and will replicate. Methods Strains The E. coli strains used in this study were MG1655 K-12 strain [21], O157:H7 Sakai EHEC strain (derivative in which the stx1 and stx2 genes were deleted by M. D. Goldberg, University of Birmingham, UK) [8], CFT073 UPEC strain [9] O42 EAEC [10] and H10407 ETEC strains [11] (from Ian R. Henderson, University of Birmingham, UK; Sequenced by the Sanger Institute: unpublished). Primers The primers used in this study are listed in table 4.

Therefore, this self-compliant W/TaO x /TiN device will have great potential

for future non-volatile memory application. Acknowledgements This work was supported by the National Science Council (NSC) of Taiwan, under contract no. NSC-102-2221-E-182-057-MY2.
