    Notes: The reaction of [Cp*IrCl2]2 with dilithium 1,2-ortho-carborane-1,2-diselenolate 3 leads to the green 16-electron diselenolene complex [Cp*Ir{Se2C2(B10H10)}] (4) which takes up two-electron ligands such as trimethylphosphane to give the 18-electron diselenolate derivative [Cp*Ir(PMe3){Se2C2(B10H10)}] (5). The molecular structures of 4 and 5 were determined by X-ray crystal structure analysis. The 77Se-nuclear shielding in 4 is lower by almost 500 ppm relative to that in 5.

    Comparative analysis of bacteria associated with different mosses by 16S rRNA and 16S rDNA sequencing (2016)
    Wiley-Blackwell
    Details
    Publication Date: 2016-08-13
    Description: To understand the differences of the bacteria associated with different mosses, a phylogenetic study of bacterial communities in three mosses was carried out based on 16S rDNA and 16S rRNA sequencing. The mosses used were Hygroamblystegium noterophilum , Entodon compressus and Grimmia montana , representing hygrophyte, shady plant and xerophyte, respectively. In total, the operational taxonomic units (OTUs), richness and diversity were different regardless of the moss species and the library level. All the examined 1183 clones were assigned to 248 OTUs, 56 genera were assigned in rDNA libraries and 23 genera were determined at the rRNA level. Proteobacteria and Bacteroidetes were considered as the most dominant phyla in all the libraries, whereas abundant Actinobacteria and Acidobacteria were detected in the rDNA library of Entodon compressus and approximately 24.7% clones were assigned to Candidate division TM7 in Grimmia montana at rRNA level. The heatmap showed the bacterial profiles derived from rRNA and rDNA were partly overlapping. However, the principle component analysis of all the profiles derived from rDNA showed sharper differences between the different mosses than that of rRNA-based profiles. This suggests that the metabolically active bacterial compositions in different mosses were more phylogenetically similar and the differences of the bacteria associated with different mosses were mainly detected at the rDNA level. Obtained results clearly demonstrate that combination of 16S rDNA and 16S rRNA sequencing is preferred approach to have a good understanding on the constitution of the microbial communities in mosses.

    Expression of FGF4 mRNA is mediated by mating behaviours in mice (2012)
    Wiley-Blackwell
    Details
    Publication Date: 2012-11-22
    Description: In mammals, breeding is preceded by species-specific mating behaviours. In this study, we investigated whether parthenogenetic embryo quality could be improved by mating behaviours in mice. To investigate this hypothesis, female mice were mated with vasectomized Kunming white male mice after superovulation. Oocytes were collected and counted at 16 h after superovulation. The oocytes were then artificially activated by medium containing 10 mM strontium chloride and 5 µg/ml cytochalasin B. Blastocysts were obtained by cultivating activated oocytes in vitro . Expression levels of reprogramming transcription factors (i.e. Oct4, Sox2, Klf4 and c-Myc ) in oocytes, apoptosis-related genes (i.e. Bax, Bcl2 and c-Myc) in cumulus cells and pluripotency-related transcription factors (i.e. Oct4, Nanog and FGF4 ) in blastocysts were analysed in samples collected from mated and unmated mice. Additionally, developmental competence of parthenogenetic embryos was used to assess following fibroblast growth factor 4 (FGF4) treatment. The results showed that the formation rate of blastocysts in unmated mice was significantly higher than that in mated mice ( p  〈 0.05). Embryo development was primarily blocked at the eight-cell stage in mated mice; however, the blastocyst formation rate did not differ significantly between groups after the addition of 25 ng/ml FGF4 to the medium at the four-cell stage ( p  〉 0.05). Moreover, the expression of the reprogramming factor Sox2 was significantly different in oocytes collected from mated versus unmated mice. Taken together, our results demonstrated that mating behaviours influenced embryonic development in vitro by decreasing FGF4 expression. Copyright © 2012 John Wiley & Sons, Ltd.

    Oral vaccination with inhibin DNA delivered using attenuated Salmonella choleraesuis for improving reproductive traits in mice (2013)
    Wiley-Blackwell
    Details
    Publication Date: 2013-10-05
    Description: The objective of this study was to examine the efficacy and safety of a novel inhibin vaccine containing inhibin α (1–32) fragments in mice. A recombinant plasmid pVAX-asd-IS was constructed by inserting recombinant inhibin α (1–32) and the hepatitis B surface antigen S into the plasmid in which the asd gene, rather than the kanamycin gene, was a selection marker. Ninety Kuming mice were divided into six groups consisting of 15 mice each. First group was (C1) injected with 200 µl of PBS, second (C2) received 1 × 10 10 CFU of crp − / asd − C500/pVAX-asd and served as vector control, third did not receive any treatment (C3), while fourth, fifth, and sixth group received 1 × 10 10 , 1 × 10 9 , 1 × 10 8 CFU of the recombinant inhibin vaccine crp − / asd − C500/pVAX-asd-IS (group T1, T2, T3), respectively. Western blotting demonstrated that recombinant expressed inhibin protein possessed immune function and that this plasmid could replicate for up to 40 generations stably. Vaccination with this strain at a dose of 1 × 10 10 CFU/200 µl per mouse induced high anti-inhibin antibody levels, significantly increased large-follicle production in T1 group ( p  〈 0.05) and average litter size ( p  〉 0.05) compared with control groups. Integration studies showed no evidence of inhibin fusion gene integrated into mice's genome 2-month after immunization. These results suggest that the vaccine described in the present study may provide a safe method to improve reproductive traits in animals. A trend towards increased litter size and significant increase in large follicle population depict that this vaccine may have direct application in large animal industry.

    Genetic research and structural dysplasia assessment of anorectal malformations in neonatal male rats induced by di(n-butyl) phthalate (2014)
    Wiley-Blackwell
    Details
    Publication Date: 2014-09-13
    Description: ABSTRACT This study was the first to investigate the genetic abnormalities and structural dysplasia of anorectal malformations (ARMs) in male rats induced by di( n -butyl) phthalate (DBP). DBP was administered to timed-pregnant rats to establish the ARM rat model. The incidence of ARMs in male offspring was 39.5%. In neonatal period, decreased body weight and anogenital distance were observed. The general image and histological analysis of male offspring confirmed the presence of ARMs. Anatomical examination of the ARM male rats revealed the dysplasia in solid organs (heart-lung, liver, spleen, and kidney). The decreases of serum testosterone concentration and androgen receptor expression in terminal rectum were indicative of the antiandrogenic effects of DBP. Moreover, significant decreased mRNA expressions of these androgen-related genes such as sonic hedgehog, Gli2, Gli3, bone morphogenetic protein 4, Wnt5a, Hoxa13, Hoxd13, fibroblast growth factor 10, and fibroblast growth factor receptor 2 were found in terminal rectum of the ARM male pubs. These results demonstrated that development of ARM rats was impaired by maternal exposure to DBP. The antiandrogenic effects of DBP disturbing the androgen-related signaling networks might play an important role in the occurrence of ARMs. © 2014 Wiley Periodicals, Inc. Environ Toxicol, 2014.

    Synthesis, Structure, Photoluminescence and Thermal Properties of Sodium Ethene-Bis-Nitrobenzenesulfonate (2012)
    Wiley-Blackwell
    Details
    Publication Date: 2012-08-25
    Description: Abstract. Sodium ethene-bis-nitrobenzenesulfonate, [Na 2 (ENS) · 6H 2 O] n ( 1 ) was synthesized through coupling reaction of o -nitrotoluenesulfonic acid in NaOH solution and characterized by single crystal X-ray diffraction, elemental analysis, IR and 1 H NMR spectroscopy, XRPD, DSC and TGA (where ENS 2– = ethene-bis-nitrobenzenesulfonate). The asymmetrical unit of ( 1 ) consists of two octahedral Na I ions, and the neighboring metal centers are bridged by μ 2 water molecules resulting in the formation of an inorganic tetranuclear unit. The tetranuclear units were connected through the ENS 2– ligands into a 2D topology net. The weak π–π stacking and H-bonding interactions further stabilized the structure. The crystals of (C 7 H 6 NO 5 S) – · (H 5 O 2 ) + ( 2 ) were obtained by post-processing the unreacted raw material to recycle. Furthermore, the rigidity and the conjugation effect of the aromatic system in compound 1 were increased through the coordination interactions of metal atoms to ligands, resulting in the emission coming from ligand enhanced with red-shifting about 9 nm of the maximal wavelength. The conjugation effects and the steric arrangement of the substituent groups play the main role to the luminescence intensity and red-shift effect.
