1Accuracy and responses of genomic selection on key traits in apple breeding显示文摘The application of genomic selection in fruit tree crops is expected to enhance breeding eficiency by increasing prediction accuracy,increasing selection intensity and decreasing generation interval.The objectives of this study were to assess the accuracy of prediction and selection response in commercial apple breeding programmes for key traits.The training population comprised 977 individuals derived from 20 pedigreed fllsib families.Historic phenotypic data were available on 10 traits related to productivity and fruit external appearance and genotypic data for 7829 SNPs obtained with an llumina 20K SNP array.From these data,a genome-wide prediction model was built and subsequently used to calculate genomic breeding values of five application fllsib families.The application families had genotypes at 364 SNPs from a dedicated 512 SNP array,and these genotypic data were extended to the high-density level by imputation.These five families were phenotyped for 1 year and their phenotypes were compared to the predicted breeding values.Accuracy of genomic prediction across the 10 traits reached a maximum value of 0.5 and had a median value of 0.19.The accuracies were strongly affected by the phenotypic distribution and heritability of traits.In the largest family,significant selection response was observed for traits with high heritability and symmetric phenotypic distribution.Traits that showed non-significant response often had reduced and skewed phenotypic variation or low heritability.Among the five application families the accuracies were uncorrelated to the degree of relatedness to the training population.The results underline the potential of genomic prediction to accelerate breeding progress in outbred fruit tree crops that still need to overcome long generation intervals and extensive phenotyping costs.Hélène Muranty Michela Troggio Inès Ben Sadok Mehdi Al Rifaï Annemarie Auwerkerken Elisa Banchi Riccardo Velasco Piergiorgio Stevanato W.Eric van de Weg Mario Di Guardo Satish Kumar François Laurens Marco C.A.M.Bink 2015Horticulture Research2015,2,1:14
2影响林木种子贮藏的因素(英文)显示文摘为了每年提供造林新需的具有生活力的种子及长期保存种质资源,贮藏种子是必要的手段。种子寿命具有遗传性,且因树种而异。种子的贮藏特性可以分成5类:正常型、亚正常型、温带顽拗型、热带顽拗型和中间型。种子含水量和贮藏温度是影响种子贮藏是否成功的两个最重要因素。但因树种及其贮藏特性不同,种子含水量和贮藏温度的最适值也不同。为了保持正常型和亚正常型种子的生活力,这类种子必须密封贮藏;但对顽拗型种子,因其需要保持种子的代谢活性及要进行有氧呼吸,则需要气体交换。Ben S P Wang J Dale Simpson 2006南京林业大学学报(自然科学版)2006,30,1:8
3Insulin like growth factor-1 increases fatty liver preservation in IGL-1 solution显示文摘AIM: To investigate the benefits of insulin like growth factor-1 (IGF-1) supplementation to serum-free institut georges lopez-1 (IGL-1) solution to protect fatty liver against cold ischemia reperfusion injury. METHODS: Steatotic livers were preserved for 24 h in IGL-1  solution supplemented with or without IGF-1 and then perfused 'ex vivo ' for 2 h at 37℃. We examined the effects of IGF-1 on hepatic damage and function (transaminases, percentage of sulfobromophthalein clearance in bile and vascular resistance). We also studied other factors associated with the poor tolerance of fatty livers to cold ischemia reperfusion injury such as mitochondrial damage, oxidative stress, nitric oxide, tumor necrosis factor-α (TNF-α) and mitogen-activated protein kinases.RESULTS: Steatotic livers preserved in IGL-1 solutionsupplemented with IGF-1 showed lower transaminase levels, increased bile clearance and a reduction in vascular resistance when compared to those preserved in IGL-1solution alone. These benefits are mediated by activation of AKT and constitutive endothelial nitric oxide synthase (eNOS), as well as the inhibition of inflammatory cytokines such as TNF-α. Mitochondrial damage and oxidative stress were also prevented.CONCLUSION: IGL-1  enrichment with IGF-1 increasedfatty liver graft preservation through AKT and eNOS activation, and prevented TNF-α release during normothermic reperfusion.Mohamed Amine Zaouali Susagna Padrissa-Altés Ismail Ben Mosbah Hassen Ben Abdennebi Olivier Boillot Antoni Rimola Dalila Saidane-Mosbahi Joan Roselló-Catafau 2010World Journal of Gastroenterology2010,16,45:6

5Imaging of liver cancer显示文摘Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality.Ben Ariff Claire R Lloyd Sameer Khan Mohamed Shariff Andrew V Thillainayagam Devinder S Bansi Shahid A Khan Simon D Taylor-Robinson Adrian KP Lim 2009World Journal of Gastroenterology2009,15,11:4

7Benefits of the use of blood conservation in scoliosis surgery显示文摘AIM To investigate whether autologous blood transfusion(ABT) drains and intra-operative cell salvage reduced donor blood transfusion requirements during scoliosis surgery.METHODS Retrospective data collection on transfusion requirements of patients undergoing scoliosis surgery is between January 2006 and March 2010. There were three distinct phases of transfusion practice over this time: Group A received 'traditional treatment' with allogeneic red cell transfusion(ARCT) in response to an intra- or postoperative anaemia(Hb < 8 g/d L or a symptomatic anaemia); Group B received intra-operative cell salvage in addition to 'traditional treatment'. In group C,ABT wound drains were used together with both intra-operative cell salvage and 'traditional treatment'.RESULTS Data from 97 procedures on 77 patients,there was no difference in mean preoperative haemoglobin levels between the groups(A: 13.1 g/d L; B: 13.49 g/d L; C: 13.66 g/d L). Allogeneic red cell transfusion was required for 22 of the 37 procedures(59%) in group A,17 of 30(57%) in group B and 16 of 30(53%) in group C. There was an overall 6% reduction in the proportion of patients requiring an ARCT between groups A and C but this was not statistically significant(χ2 = 0.398). Patientsin group C received fewer units(mean 2.19) than group B(mean 2.94)(P = 0.984) and significantly fewer than those in group A(mean 3.82)(P = 0.0322). Mean length of inpatient stay was lower in group C(8.65 d) than in groups B(12.83) or A(12.62).CONCLUSION When used alongside measures to minimise blood loss during surgery,ABT drains and intra-operative cell salvage leads to a reduced need for donor blood transfusion in patients undergoing scoliosis surgery.Peter R Loughenbury Lyeanda Berry Ben T Brooke Abhay S Rao Robert A Dunsmuir Peter A Millner 2016World Journal of Orthopedics2016,7,12:3
8Direct characterization of a nonlinear photonic circuit’s wave function with laser light显示文摘Integrated photonics is a leading platform for quantum technologies including nonclassical state generation1–4,demonstration of quantum computational complexity5 and secure quantum communications6.As photonic circuits grow in complexity,full quantum tomography becomes impractical,and therefore an efficient method for their characterization7,8 is essential.Here we propose and demonstrate a fast,reliable method for reconstructing the two-photon state produced by an arbitrary quadratically nonlinear optical circuit.By establishing a rigorous correspondence between the generated quantum state and classical sum-frequency generation measurements from laser light,we overcome the limitations of previous approaches for lossy multimode devices9,10.We applied this protocol to a multi-channel nonlinear waveguide network and measured a 99.28±0.31%fidelity between classical and quantum characterization.This technique enables fast and precise evaluation of nonlinear quantum photonic networks,a crucial step towards complex,largescale,device production.Francesco Lenzini Alexander N Poddubny James Titchener Paul Fisher Andreas Boes Sachin Kasture Ben Haylock Matteo Villa Arnan Mitchell Alexander S Solntsev Andrey A Sukhorukov Mirko Lobino 2018Light(Science & Applications)2018,7,1:2
9Enhancement of surface wettability via micro-and nanostructures by single point diamond turning显示文摘Studies on surface wettability have received tremendous interest due to their potential applications in research and industrial processes. One of the strategies to tune surface wettability is modifying surface topography at micro-and nanoscales. In this research, periodic micro-and nanostructures were patterned on several polymer surfaces by ultra-precision single point diamond turning to investigate the relationships between surface topographies at the micro-and nanoscales and their surface wettability. This research revealed that single-point diamond turning could be used to enhance the wettability of a variety of polymers, including polyvinyl chloride(PVC), polyethylene 1000(PE1000), polypropylene copolymer(PP) and polytetrafluoroethylene(PFTE), which cannot be processed by conventional semiconductor-based manufacturing processes. Materials exhibiting common wettability properties(θ≈ 90°) changed to exhibit 'superhydrophobic' behavior(θ > 150°). Compared with the size of the structures, the aspect ratio of the void space between micro-and nanostructures has a strong impact on surface wettability.Nicolás Cabezudo Jining Sun Behnam Andi Fei Ding Ding Wang Wenlong Chang Xichun Luo Ben B.Xu 2019Nanotechnology and Precision Engineering2019,2,1:2
