| 1 | Evaluation of the yield and nitrogen use efficiency of the dominant maize hybrids grown in North and Northeast China显示文摘Breeding high-yielding and nutrient-efficient cultivars is one strategy to simultaneously resolve the problems of food security,resource shortage,and environmental pollution.However,the potential increased yield and reduction in fertilizer input achievable by using high-yielding and nutrient-efficient cultivars is unclear.In the present study,we evaluated the yield and nitrogen use efficiency(NUE) of 40 commercial maize hybrids at five locations in North and Northeast China in 2008 and 2009.The effect of interaction between genotype and nitrogen(N) input on maize yield was significant when the yield reduction under low-N treatment was 25%-60%.Based on the average yields achieved with high or low N application,the tested cultivars were classified into four types based on their NUE:efficient-efficient(EE) were efficient under both low and high N inputs,high-N efficient(HNE) under only high N input,low-N efficient(LNE) under only low N input,and nonefficient-nonefficient under neither low nor high N inputs.Under high N application,EE and HNE cultivars could potentially increase maize yield by 8%-10% and reduce N input by 16%-21%.Under low N application,LNE cultivars could potentially increase maize yield by 12%.We concluded that breeding for N-efficient cultivars is a feasible strategy to increase maize yield and/or reduce N input. | CHEN FanJun FANG ZenGuo GAO Qiang YE YouLiang JIA LiangLiang YUAN LiXing MI GuoHua ZHANG FuSuo | 2013 | Science China(Life Sciences)2013，56，6： | 27 |
| 2 | Pore throat characteristics of tight sandstone of Yanchang Formation in eastern Gansu,Ordos Basin显示文摘An important factor to evaluate reservoir quality is the pore-throat size.However,the strong heterogeneity makes it difficult to characterize the pore-throat distribution in tight reservoirs.The field emission scanning electron microscope(FESEM),high pressure mercury injection and rate-controlled mercury injection are used to investigate the pore-throat size distribution in tight sandstone reservoirs of Member 7 of the Yanchang Formation in eastern Gansu,Ordos Basin,and studies of the pore throat size controlling on physical property of the tight sandstone reservoirs are also carried out.The result shows that the pore type is mainly dominated by the residual intergranular pore,dissolution pore,micropore and a few micro-fractures;the high-pressure mercury injection experiment indicates that the pore-throat size ranges from 0.0148 μm to 40mm,the pore throat more than 1 mm is less;the ratecontrolled mercury injection experiment reveals that for samples with different physical properties,the pore radius mainly varies from 80 μm to 350 μm;the throat radius exhibits the strong heterogeneity,and is from 0.12 μm to 30μm;the pore-throat size can be effectively characterized by combination of high-pressure and rate-controlled mercury injections,and it varies from 0.0148 μm to 350 μm.The permeability is mainly controlled by the large pore throat(>R_(50))which accounts for a small proportion;in the tight sandstone with the permeability greater than 0.1 mD,the permeability is mainly controlled by the micropore and mesopore;in the tight sandstone with the permeability smaller than 0.1 mD,the permeability is mainly controlled by the nanopore and micropore;the proportion of small pore throat increases with reduction of permeability,it is important that the small pore throat influences the reservoir storage property though its effect on permeability are small. | Hao Wu Chunlin Zhang Youliang Ji Rui'e Liu Shang Cao Sheng Chen Yunzhao Zhang Ye Wang Wei Du Gang Liu | 2018 | Petroleum Research2018，3，1： | 7 |

| 13 | Evidence of bisphosphonate-conjugated sitafloxacin eradication of established methicillin-resistant S.aureus infection with osseointegration in murine models of implant-associated osteomyelitis显示文摘Eradication of MRSA osteomyelitis requires elimination of distinct biofilms.To overcome this,we developed bisphosphonateconjugated sitafloxacin(BCS,BV600072)and hydroxybisphosphonate-conjugate sitafloxacin(HBCS,BV63072),which achieve“target-and-release”drug delivery proximal to the bone infection and have prophylactic efficacy against MRSA static biofilm in vitro and in vivo.Here we evaluated their therapeutic efficacy in a murine 1-stage exchange femoral plate model with bioluminescent MRSA(USA300LAC::lux).Osteomyelitis was confirmed by CFU on the explants and longitudinal bioluminescent imaging(BLI)after debridement and implant exchange surgery on day 7,and mice were randomized into seven groups:1)Baseline(harvested at day7,no treatment);2)HPBP(bisphosphonate control for BCS)+vancomycin;3)HPHBP(hydroxybisphosphonate control for HBCS)+vancomycin;4)vancomycin;5)sitafloxacin;6)BCS+vancomycin;and 7)HBCS+vancomycin.BLI confirmed infection persisted in all groups except for mice treated with BCS or HBCS+vancomycin.Radiology revealed catastrophic femur fractures in all groups except mice treated with BCS or HBCS+vancomycin,which also displayed decreases in peri-implant bone loss,osteoclast numbers,and biofilm.To confirm this,we assessed the efficacy of vancomycin,sitafloxacin,and HBCS monotherapy in a transtibial implant model.The results showed complete lack of vancomycin efficacy while all mice treated with HBCS had evidence of infection control,and some had evidence of osseous integrated septic implants,suggestive of biofilm eradication.Taken together these studies demonstrate that HBCS adjuvant with standard of care debridement and vancomycin therapy has the potential to eradicate MRSA osteomyelitis. | Youliang Ren Jason Weeks Thomas Xue Joshua Rainbolt Karen L.de Mesy Bentley Ye Shu Yuting Liu Elysia Masters Philip Cherian Charles E.McKenna Jeffrey Neighbors Frank H.Ebetino Edward M.Schwarz Shuting Sun Chao Xie | 2023 | Bone Research2023，11，4： | 0 |
| 14 | Facile synthesis of silicapolymer hybrids via simultaneous RAFT process and hydroxyl-alkoxysilane coupling reaction显示文摘This study aimed at the synthesis of silica particles grafted with better-defined homopolymers and block copolymers by tandem approach.Z-functionalized Sbenzyl S’-(3-trimethoxysilyl)propyltrithiocarbonate(BTPT)was used as a couplable RAFT agent to synthesize the target inorganic-organic hybrids.Simultaneous coupling reaction and RAFT process using silica particles and BTPT as raw materials efficiently afforded homopolymers grafted silica,and RAFTsynthesized macro chain transfer agents withω-terminal trimethoxysilane moiety were utilized to mediate graft reaction to prepare silica particles grafted with di-,tri-and tetrablock copolymers comprised of polymer segments such as polystyrene,polyacrylamides and polyacrylates.When the grafted chains had molecular weights ranging between 3920 and 24800 g/mol,the molar grafting ratios,which were dependent on reaction conditions and types and compositions of grafted chains,were estimated to be in the range of 15.2–101μmol/g,and grafted polymers usually had polydispersity indices lower than 1.3,revealing that the grafting process was almost controllable.To the best of our knowledge,this versatile tandem approach is one of the most facile techniques to prepare silica particles grafted with polymeric chains with controlled molecular weight,low polydispersity and precise composition due to its minimal reaction steps,mild conditions,straightforward synthesis and satisfactory controllability. | Chunnuan YE Weina QI Xinhua YU Peipei ZHANG Tengteng HOU Youliang ZHAO | 2011 | Frontiers of Chemistry in China2011，6，3： | 0 |
