No full textNext-Generation Sequencing: Application in Liver Cancer—Past, Present and Future?
No full textHepatocellular Carcinoma (HCC) is the third most deadly malignancy worldwide characterized by phenotypic and molecular heterogeneity. In the past two decades, advances in genomic analyses have formed a comprehensive understanding of different underlying pathobiological layers resulting in hepatocarcinogenesis. More recently, improvements of sophisticated next-generation sequencing (NGS) technologies have enabled complete and cost-efficient analyses of cancer genomes at a single nucleotide resolution and advanced into valuable tools in translational medicine. Although the use of NGS in human liver cancer is still in its infancy, great promise rests in the systematic integration of different molecular analyses obtained by these methodologies, i.e., genomics, transcriptomics and epigenomics. This strategy is likely to be helpful in identifying relevant and recurrent pathophysiological hallmarks thereby elucidating our limited understanding of liver cancer. Beside tumor heterogeneity, progress in translational oncology is challenged by the amount of biological information and considerable “noise” in the data obtained from different NGS platforms. Nevertheless, the following review aims to provide an overview of the current status of next-generation approaches in liver cancer, and outline the prospects of these technologies in diagnosis, patient classification, and prediction of outcome. Further, the potential of NGS to identify novel applications for concept clinical trials and to accelerate the development of new cancer therapies will be summarized

Mapping Closure Approximation for Reactive Scalars in Random Flows
No full textThe Mapping Closure Approximation (MCA) approach is developed to describe the statistics of both conserved and reactive scalars in random flows. The statistics include Probability Density Function (PDF), Conditional Dissipation Rate (CDR) and Conditional Laplacian (CL). The statistical quantities are calculated using the MCA and compared with the results of the Direct Numerical Simulation (DNS). The results obtained from the MCA are in agreement with those from the DNS. It is shown that the MCA approach can predict the statistics of reactive scalars in random flows
Regularity of the solutions for micro–macro models near equilibrium
No full textAbstractIn this paper, we study the regularity of solutions to two microscopic–macroscopic models: Hookean spring model and FENE dumbbell model. By making use of the structure of Fokker–Planck operator and establishing the general Hardy–Littlewood's inequality, we show that the classical solutions near the equilibrium obtained in [F. Lin, C. Liu, Ping Zhang, On a micro–macro model for polymeric fluids near equilibrium, Comm. Pure Appl. Math. 60 (6) (2007) 838–866] and [F. Lin, Ping Zhang, The FENE dumbbell model near equilibrium, Acta Math. Sinica (Chin. Ser.) 24 (2008) 529–538] become smooth with respect to the end-to-end vector variable q for any positive time

No full textAbstractIn this paper, we study the number of zeros of Abelian integrals and the monotonicity of period functions for planar quasihomogeneous Hamiltonian vector fields. The result for Abelian integrals extends the recent work of Li et al. [C. Li, W. Li, J. Llibre, Z. Zhang, Polynomial systems: A lower bound for the weakened 16th Hilbert problem, Extracta Math. 16 (3) (2001) 441–447] and Llibre and Zhang [J. Llibre, X. Zhang, On the number of limit cycles for some perturbed Hamiltonian polynomial systems, Dyn. Contin. Discrete Impuls. Syst. Ser. A Math. Anal. 8 (2) (2001) 161–181]
Half-ZF beamforming scheme for downlink two-user multiple input single output-based non-orthogonal multiple access systems
No full textThe authors investigate the beamforming (BF) problem to minimise the power consumption for the downlink 2-user multiple input single output-based non-orthogonal multiple access system. Inspired from the conventional zero-forcing (ZF) scheme, they propose the Half-ZF scheme which only mitigates the interference introduced by the signal of the cell-interior user through the ZF method. Meanwhile, the interference introduced by the signal of the cell-edge user is removed through the SIC technology. We derive the closed-form expression for the BF vectors of the two users under the Half-ZF scheme. The optimal power consumption for the Half-ZF scheme is analysed and the corresponding solution of the BF factors are also obtained. Compared with the conventional ZF scheme, both the Half-ZF scheme and the existing quasi-degradation (QD) scheme can achieve lower power consumption than the ZF scheme. However, the Half-ZF scheme can achieve this advantage under more relaxed conditions. Consequently, the Half-ZF scheme consumes lower power than the QD scheme when combined with the ZF scheme in practical systems.SCI(E)ARTICLE101633-16401
Identification and expression analysis of the ZF-HD gene family in castor
No full text[Objective] The ZF-HD family genes of castor were identified and analyzed by sequence analysis,
phylogenetic analysis, promoter and expression pattern analysis, to provide a reference for further
study of the function of ZF-HD genes in castor. [Methods] Based on the whole genome data of castor,
ZF-HD genes were identified, and bioinformatics and expression analysis under abiotic stress were carried
out. [Results] A total of 13 ZF-HD genes were identified from castor, which were unevenly distributed on
Chr1-Chr10. All 13 RcZF-HD proteins were hydrophilic unstable proteins, and were localized in the nucleus.
The RcZF-HD genes were clustered into three subgroups, and the number of genes in each group was
different. The gene structure was conserved within the group but diversified between groups. RcZF-HD
genes had a large number of tissue-specific elements, stress response elements, and hormone response elements.
The ZF-HD genes were widely responsive to abiotic stresses and their expression was tissue-specific.
[Conclusion] A total of 13 ZF-HD genes were identified in castor. It is known that members of the
castor ZF-HD gene family play an important role in responding to abiotic stress, this research provides
theoretical basis for the study of castors stress resistance

The reporter gene, either chloramphenicol acetyltransferase (CAT), or GFP is located downstream from a weak derivative promoter (P) on pDB series plasmids. A 9 bp target site for binding by the ZF is located at a specific distance from the start of transcription. On the pA series of plasmids, the gene for the ZF is fused to a fragment of the α-subunit of RNA polymerase ([]) via a sequence coding for an amino acid linker. Binding of the RpoA[1–248]–ZF fusion to the 9 bp site in the reporter plasmid recruits the other RNA polymerase subunits to stimulate transcription of the reporter gene
