| 1 | Effects of different dietary energy and protein levels and sex on growth performance,carcass characteristics and meat quality of F1 Angus x Chinese Xiangxi yellow cattle显示文摘Background:The experiment evaluated the effect of nutrition levels and sex on the growth performance,carcass characteristics and meat quality of F1 Angus × Chinese Xiangxi yellow cattle.Methods:During the background period of 184 d,23 steers and 24 heifers were fed the same ration,then put into a2×2×2 factorial arrangement under two levels of- dietary energy(TON:70/80%DM),protein(CP:11.9/14.3%DM)and sex(S:male/female) during the finishing phase of 146 d.The treatments were-(1) high energy/low protein(HELP),(2) high energy/high protein(HEHP),(3) low energy/low protein(LELP) and(4) low energy/high protein(LEHP).Each treatment used 6 steers and 6 heifers,except for HELP- 5 steers and 6 heifers.Results:Growth rate and final carcass weight were unaffected by dietary energy and protein levels or by sex.Compared with the LE diet group,the HE group had significantly lower dry matter intake(DMI,6.76 vs.7.48 kg DM/d),greater chest girth increments(46.1 vs.36.8 cm),higher carcass fat(19.9 vs.16.3%) and intramuscular fat content(29.9 vs.22.8%DM).The HE group also had improved yields of top and medium top grade commercial meat cuts(39.9 vs.36.5%).The dressing percentage was higher for the HP group than the LP group(53.4 vs.54.9%).Steers had a greater length increment(9.0 vs.8.3 cm),but lower carcass fat content(16.8 vs.19.4%) than heifers.The meat quality traits(shear force value,drip loss,cooking loss and water holding capacity) were not affected by treatments or sex,averaging 3.14 kg,2.5,31.5 and 52.9%,respectively.The nutritive profiles(both fatty and amino acid composition) were not influenced by the energy or protein levels or by sex.Conclusions:The dietary energy and protein levels and sex significantly influenced the carcass characteristics and chemical composition of meat but not thegrowth performance,meat quality traits and nutritive profiles. | Lingyan Li Yuankui Zhu Xianyou Wang Yang He Binghai Cao | 2014 | Journal of Animal Science and Biotechnology2014,5,4: | 21 |
| 2 | Effect of biochar applied with plant growth-promoting rhizobacteria(PGPR)on soil microbial community composition and nitrogen utilization in tomato显示文摘Plant growth-promoting rhizobacteria(PGPR)represent an important microbial community group and have beneficial effects on plant growth and development.A pot experiment was conducted to study the effect of biochar applied with PGPR on the soil microbial community composition and nitrogen use efficiency(NUE)of tomato,which could provide a theoretical basis for rational fertilization.Six treatments were designed:no nitrogen(N),PGPR,or biochar control(CK);biochar without N or PGPR(BCK);N without PGPR or biochar(U);N and PGPR without biochar(UP);N and biochar without PGPR(UB);and N,PGPR,and biochar(UBP).The tomato yield in the UP treatment was 9.09% lower than that in the U treatment,whereas that in the UB treatment was 19.93% higher than that in the U treatment.The tomato yield in the UBP treatment was 32.45%,45.69%,and 10.44% higher than those in the U,UP,and UB treatments,respectively.Biochar combined with PGPR increased the relative abundance of Nitrospira and Bradyrhizobium in the soil.At the tomato maturity stage,the soil NO_(3)^(-)-N content in the UBP treatment was 87.12%,88.12%,and 31.04% higher than those in the U,UP,and UB treatments,respectively.The NUE in the UP treatment was 4.03% lower than that in the U treatment,and that in the UBP treatment was 13.63%,17.66%,and 10.77% higher than those in the U,UP,and UB treatments,respectively.This study showed that biochar combined with PGPR can improve soil microbial community structure and increase the NUE of tomato. | Yuan WANG Wenqing LI Binghai DU Hanhao LI | 2021 | Pedosphere2021,31,6: | 7 |
| 3 | miR-23b promotes cutaneous wound healing through inhibition of the inflammatory responses by targeting ASK1显示文摘Wound healing is a complicated event that develops in three overlapping phases:inflammatory, proliferative,and remodeling.MicroRNAs (miRNAs)have been proved to play an important role in the healing process of skin trauma,and alteration of specific miRNA expression during different phases may be associated with abnormal wound healing.In this study,we determined the variation of miR-23b expression after trauma in normal mice and in cultured cells exposed to lipopolysaccharide.We further demonstrated that excessive miR-23b could significantly accelerate wound healing in vivo.Up-regulation of miR-23b decreases infiltration of inflammatory cells,as evidenced by pathologic staining.Meanwhile,miR-23b could significantly inhibit the expression of pro-inflammatory cytokines,including TNF-α,IL-1β,IL-6,and Ccl2,and significantly increase antiinflammatory factor IL-10.Furthermore,miR-23b could also promote α-SMA expression in a fiber pattern and increase the expression of Col1a1 and Col3a1.Importantly,we also showed that miR- 23b could inhibit inflammation to promote wound healing by targeting apoptotic signal-regulating kinase 1 (ASK1).Notably,knockdown of ASK1 could reduce inflammation factor expression in vitro.Together,our data reveal that miR-23b is a potent therapeutic agent for cutaneous wound healing that shortens the period of inflammatory responses and promotes keratinocyte migration for the re-epithelialization of wound sites. | Hongzhi Li Xiao Han Kuiyang Zuo Li Li Jieting Liu Xiaohuan Yuan Yongchao Shen Minglong Shao Daxin Pang Yanhui Chu Binghai Zhao | 2018 | Acta Biochimica et Biophysica Sinica2018,50,11: | 5 |
| 4 | The abnormal behavior of polymers glass transition temperature increase and its mechanism显示文摘In terms of the classical theory in textbooks, the two components with phase separation in a binary polymer blend will, depending on their compatibility, have their respective Tg get closer or remain in their original values. According to the classical theory, the Tg of plastic component shall remain unchanged or move toward the lower Tg of rubber component in a rubber/plastic blend. However, ultra-fine full-vulcanized powdered rubber (UFPR) with a diameter of ca. 100 nm can simultaneously increase the toughness and the Tg of plastics, which is abnormal and is difficult to explain by classical theory. In this feature article, the abnormal behavior and its mechanism are discussed in detail. | WANG Xiang QI GuiCun ZHANG XiaoHong GAO JianMing LI BingHai SONG ZhiHai QIAO JinLiang | 2012 | Science China Chemistry2012,55,5: | 2 |

| 6 | Anhydrous based shear-thickening polishing of KDP crystal显示文摘Based on the special physical–chemical characteristics of optical crystal in the field of aeronautics,a new anhydrous based shear-thickening polishing(ASTP)method has been proposed to restrain deliquescence and to improve physical properties for KDP machining.The ultraprecision polishing of KDP crystal is completed by ASTP.A kind of anhydrous based thickening polishing slurry(ATPS)was proposed in our work,and high-performance rheological properties were determined to achieve the ASTP of KDP crystal.A material removal model of ASTP in KDP machining is established,followed by the verification experiment of the prediction model.The maximum error of the predictive model is only 9.8%,which proves the validity of the material removal model for KDP polishing.The polishing experiments were carried out on the polishing platform developed by ourselves.The results show that the new polishing method can polish20 mm×20 mm×5 mm KDP crystal and obtain a super-smooth surface with a surface roughness of 1.37 nm and high shape accuracy.The surface accuracy of polished KDP crystal reaches up to0.68 k(RMS).The experimental results show that the ASTP is a potential ultra-precision machining method for KDP crystal. | Min LI Minghui LIU Oltmann RIEMER Fangzeng SONG Binghai LYU | 2021 | Chinese Journal of Aeronautics2021,34,6: | 1 |
| 7 | Anti-solvent assisted treatment for improved morphology and efficiency of lead acetate derived perovskite solar cells显示文摘An efficient solution-processable route employing Pb(Ac)2 as lead source and anti-solvent treatment to achieve fully covered and homogenous perovskite films is reported. The effect of different solution methods and device architectures on the morphologies of perovskite films were systematically investigated. Our results show that the planar perovskite layer fabricated by one-step solution method achieved fully covered and pinhole-free films. Further anti-solvent treatment using chlorobenzene (CB) promoted a perovskite film with highly smooth surfaces and enlarged grain sizes. Device fabricated from CB treated perovskite film achieved a best PCE of 15.80%, in comparison with 14.02%for the untreated device. These results evidently suggest a feasible route towards controlling the crystallization and morphology of planar heterojunction (PHJ) PSCs for improved efficiency. | Mengqin Kong Hang Hu Kingsley Egbo Binghai Dong Li Wan Shimin Wang | 2019 | Chinese Chemical Letters2019,30,6: | 1 |
| 8 | Manufacture of the Ultrafine Grain WC/Co Cemented Carbides by Combined Sintering Processing显示文摘A new kind of sintering process, combined sintering process. i.e. vacuum sintering plus hot isolate pressure sintering (HIP), was introduced for producing ultrafine WC-10% Co (mass fraction. so as the follows) cemented carbides. The effects of some processing parameters on the microstructure and mechanical properties of the obtained cemented carbides were studied. The results show that the rapid shrinkage and the pronounced densification of tile cemented carbides took place during the vacuum sintering stage, which is intinaately correlated with the local liquid sintering occurred during this earl} sintering stage for the high surface activity of ultrafine WC-Co powder. The way of high pressure imposing. isothermal treatment cycle during ac.acuum sintering and HIP sintering stage directly influence the densitication of compacts and the mechanical properties of the produced WC-10%Co cemented carbides. | Binghai Liu Yue Zhang Shixi Ouyang Qikai Li(Institute of Technical Physics and Chemistry, East China University of Science and Technology , Shanghai 200237, China)(Material Science and Engineering School.
