Objective: The objective of the present study was to determine whether mango saponin (MS) could be used as a feed additive in broiler chicks by evaluating growth performance, carcass characteristics, meat quality, and plasma biochemical indices. Methods: A total of 216 1-d-old Arbor Acres male broiler chicks were randomly assigned into three dietary treatments supplemented with 0 (control), 0.14% (MS 0.14%), or 0.28% (MS 0.28%) MS. Each treatment had six replicates (cages) with 12 chicks each. The feeding trial lasted for six weeks. Results: Compared with the control, dietary supplemented with 0.14% or 0.28% MS increased average daily weight gain of chicks in the grower (22 to 42 d) and the whole (1 to 42 d) phases, and the final body weight of chicks on d 42 was higher in MS supplemented groups (p<0.05). Lower L45 min* (lightness) and L24 h* values, lower b24 h* (yellowness) value, and higher a45 min* (redness) and a24 h* values of the breast muscle were observed in chicks fed with 0.28% MS on d 42 (p<0.05). The total antioxidant capacity in plasma increased in MS 0.14% group on d 21 (p<0.001). Lower contents of plasma total cholesterol and triglyceride were observed in chicks fed with 0.28% MS on d 21 and d 42, whereas the group supplemented with 0.14% MS only decreased plasma triglyceride content on d 21 (p<0.05). The glucose content in plasma decreased in MS 0.28% group on d 42 (p<0.001). Conclusion: Overall, MS could be used as a feed additive in broiler chicks, and the supplemental level of 0.28% MS in diet could improve growth performance, meat quality, and plasma lipid metabolism in broiler chicks.
Expression Analysis of the Mx Gene and Its Genome Structure in Chickens

Among the known interferon-induced antiviral mechanisms, the Mx pathway is one of the most powerful pathways. The Mx protein has direct antiviral activity and inhibits a wide range of viruses by blocking an early stage of the viral replication cycle. Cloning, characterization, and expression of Mx in vivo and in vitro have been conducted. The chicken Mx gene spans 21 kb and is made up of 14 exons and 13 introns, of which the promoter region was analyzed. The real-time PCR results showed that Mx expression was increased in chicken embryo fibroblasts (CEF) after 12- and 24-h induction with polyI: C. Induction of Mx expression by poly I: C in vivo revealed tissue-specific patterns among the chicken tissues tested. A trace expression of Mx was detected in healthy chicken liver tissues from adult chickens without inducement; the expression levels in the liver, heart, and gizzard were higher than in the muscle and kidney. This is the first report to demonstrate the expression of a glutathione-S-transferase-tagged-Mx fusion protein of 75 KDa, as well as the biological activity tested by SDS-PAGE and western blotting.

<B>Graphic Abstract</B> <P>A novel memory cell structure with a Pt/Ti-doped NiO/Pt architecture is shown to exhibit the lowest write current reported thus far for a unipolar switching resistance-change-based device, as shown in the figure. The write current decreases dramatically upon scaling to cell sizes smaller than 100 nm×100 nm. High-density universal memory can be fabricated by combining this node element with a selective switch. <img src='wiley_img/09359648-2008-20-5-ADMA200702081-content.gif' alt='wiley_img/09359648-2008-20-5-ADMA200702081-content'> </P>

<P>We report a systematic study on the magnetic, magnetocaloric (MC), specific heat and magnetoelectric (ME) properties of the single crystals of rare-earth orthochromites, RCrO3 (R = Dy, Nd, Er, Tb). Interesting stair-like metamagnetic transitions were observed for the first time in TbCrO3 crystals. Intrinsic large anisotropy in the magnetic and ME properties were also revealed in all of the RCrO3 crystals. The reorientation/ordering of the rare earth R3+ spins was observed to be accompanied with large MC, rotating MC and ME effects. These behaviors are found be closely related to the R-R and R-Cr interactions in these chromites. In particular, the ME effect can be ascribed to the spin phonon coupling. All these results suggest the essential and unique role of 4f electrons of rare earth ions in these chromites.</P>

Among Aurivillius layer-structured materials, CaBi2Nb2O9 is a best potential candidate for ultrahigh-temperature applications because of its highest Curie temperature of about 940 ◦C. In this paper, (1-x)CaBi2Nb2O9- xBaZr0.2Ti0.8O3 composite ceramics were prepared by conventional solid-state sintering method. The dielectric results show that the introduction of BaZr0.2Ti0.8O3 not only increases the permittivity of the material, but also reduces its dielectric loss. The optimum electrical properties were obtained in the x = 0.01 sample with piezoelectric coefficient (d33) of 15.1 pC/N and high ferroelectric remnant polarization (Pr) of 9.9 μC/cm2. Furthermore, the composite samples show good thermal depoling performance, the d33 of the x = 0.01 sample is 13.8 pC/N, which is about 91% of the initial value after depoling at 800 ◦C. Therefore, (1-x)CaBi2Nb2O9- xBaZr0.2Ti0.8O3 is one of the candidates for high temperature piezoelectric materials.
