1东方蜜蜂高效的卫生行为机制对于西方蜜蜂抗病育种的启示显示文摘西方蜜蜂(Apismellifera)在世界各地大范围的蜂群损失现象已引起科学界和公众的广泛关注,其健康状况与东方蜜蜂(Apis cerana)相比明显较劣。东方蜜蜂群内可检测到的病原体和寄生虫相对较少,即它们对于生物威胁具有更强的抵抗力,即便是面对异种入侵的新病原(如蜜蜂残翅病毒)。Lin Z Page P Li L Qin Y Zhang Y Hu F Neumann P Zheng H Dietemann V 蔺哲广 郑火青 胡福良 2016中国蜂业2016,67,12:5

3Oxygen and Nitrogen Effects on MC Carbide in K465 Nickel-Base Superalloy显示文摘Effects of oxygen and nitrogen on MC carbide in nickel-base superalloy K465 were investigated, because neither of the two gas elements was found to decide MC carbide morphology monotonically. The morphology of MC carbide under alloy solidified in conventional investment casting condition was observed to transform from script-type to block-type with the total oxygen and nitrogen content (gas content) in samples rising up from 1.2×10-6 mol/g to 2.6×10-6 mol/g. The area fraction and composition of the MC carbide also varied with increase of gas content. However, the morphology of MC carbide kept to be script-type even when gas content was up to 3.4×10-6 mol/g in samples solidified with a much higher cooling rate. These results indicate that effects of gas content on formation of MC carbide can be observed in specimens solidified with low cooling rate, but such changes in MC carbide cannot be found when the cooling rate is high.Wang L N Zheng Q Sun X F Guan H R Hu Z Q 2009稀有金属材料与工程2009,38,A03:4
4GLOBAL STABILITY IN TIME-DELAYED 3-DIMENSIONAL RICHARDS MODEL显示文摘We obtain the global attractivity and global asymptotical stability of positive equilibria to a 3-dimensional Richards model with delays. Our results do not depend on the size-asymmetry parameter which measures the degree of the curvature of size-growth among individuals over the entire growth curve, and the shape parameter which affects the shape of model curve. Lastly, we gave a numerical simulation to verify the feasibility of our main results.Lifei Zheng (College of Science, Northwest A and F University, Yangling 712100, Shaan’xi) Huiyan Zhao (College of Plant Protection, Northwest A and F University, Yangling 712100, Shaan’xi) 2010Annals of Differential Equations2010,26,1:3

6Development of a reverse transcription quantitative polymerase chain reaction-based assay for broad coverage detection of African and Asian Zika virus lineages显示文摘The Zika virus(ZIKV) is an arbovirus that has spread rapidly worldwide within recent times. There is accumulating evidence that associates ZIKV infections with Guillain-Barré Syndrome(GBS) and microcephaly in humans. The ZIKV is genetically diverse and can be separated into Asian and African lineages. A rapid, sensitive, and specific assay is needed for the detection of ZIKV across various pandemic regions. So far, the available primers and probes do not cover the genetic diversity and geographic distribution of all ZIKV strains. To this end, we have developed a one-step quantitative reverse transcription polymerase chain reaction(qRT-PCR) assay based on conserved sequences in the ZIKV envelope(E) gene. The detection limit of the assay was determined to be five RNA transcript copies and 2.94 × 10^(–3) 50% tissue culture infectious doses(TCID50) of live ZIKV per reaction. The assay was highly specific and able to detect five different ZIKV strains covering the Asian and African lineages without nonspecific amplification, when tested against other flaviviruses. The assay was also successful in testing for ZIKV in clinical samples. Our assay represents an improvement over the current methods available for the detection ZIKV and would be valuable as a diagnostic tool in various pandemic regions.Yang Yang Gary Wong Baoguo Ye Shihua Li Shanqin Li Haixia Zheng Qiang Wang Mifang Liang George F Gao Lei Liu Yingxia Liu Yuhai Bi 2017Virologica Sinica2017,32,3:3
