ABSTRACT: In this paper, the negative parity low-spin states of even–odd 187–197Pt isotopes have been studied within the framework of the Interacting Boson–Fermion Model (IBFM-1). The single fermion is assumed to be in one of the 2f5/2, 3p3/2 and 3p1/2 single-particle orbits. The calculated negative parity low-states energy spectra agree quite well with the experimental data. The B(E2)values have been also calculated and compared with the experimental data. The calculated energy levels and B(E2)are in good agreement with experimental data than that in the previous study for 195Pt isotope. Furthermore, the energy levels, electric quadrupole transition probabilities and the potential energy surface for even–even platinum isotopes (as core for even–odd nuclei) have been calculated within framework of the Interacting Boson Model (IBM-1). The predicted energy levels and B(E2)transition probabilities results are reasonably consistent with the experimental data. The contour plot of the potential energy surfaces shows all interesting nuclei are deformed and have γ-unstable-like characters.

ABSTRACT: Four gluco-triazole conjugates were synthesized employing Cu(I) catalyzed click reactions between peracetylated glucosyl azide and alkyl-(propynoxy)ethyl-triazoles which in turn were prepared under similar reaction conditions using the appropriate alkyl azide (C7, C8, C10, and C12) and but-3-yn-1-ol. Removal of the acetyl protecting groups afforded additional four compounds. All eight conjugates were assessed toward inhibition of bacterial growth (Escherichia coli, Staphylococcus aureus). Slight growth inhibition compared to kanamycin was observed at a concentration of 20μg/mL, while no growth inhibition was observed at the lowest concentration (5μg/mL).

ABSTRACT: A feeding trial was conducted to determine the effect of dietary administration of Pediococcus acidilactici MA18/5M and short chain fructooligosaccharides (scFOS) on Atlantic salmon (Salmo salar L.) intestinal health. Salmon (initial average weight 250 g) were allocated into triplicate sea pens and were fed either a control diet (commercial diet: 45% protein, 20% lipid) or a synbiotic treatment diet (control diet + P. acidilactici at 3.5 g kg(-1) and 7g kg(-1) scFOS) for 63 days. At the end of this period, fish were sampled for intestinal microbiology, intestinal histology and the expression of selected immune-related genes (IL1β, TNFα, IL8, TLR3 and MX-1) in the intestine. Compared to the control fish, the total bacterial levels were significantly lower in the anterior mucosa, posterior mucosa and posterior digesta of the synbiotic fed fish. qPCR revealed good recovery (log 6 bacteria g(-1)) of the probiotic in the intestinal digesta of the synbiotic fed fish and PCR-DGGE revealed that the number of OTUs, as well as the microbial community diversity and richness were significantly higher in the anterior digesta of the synbiotic fed fish than the control. Compared to the control fed fish, the mucosal fold (villi) length and the infiltration of epithelial leucocytes were significantly higher in the anterior and posterior intestine, respectively, in the synbiotic group. Real-time PCR demonstrated that all of the genes investigated were significantly up-regulated in the anterior and posterior intestine of the synbiotic fed salmon, compared to control group. At the systemic level, serum lysozyme activity was significantly higher in the synbiotic fed fish and growth performance, feed utilisation and biometric measurements (condition factor, gutted weight and gut loss) were not affected. Together these results suggest that the synbiotic modulation of the gut microbiota has a protective action on the intestinal mucosal cells, improving morphology and stimulating the innate immune response without negatively affecting growth performance or feed utilization of farmed Atlantic salmon.
