肠道微生态与肝移植及肝移植术后缺血性胆道病变的关系

近年来随着聚合酶链反应-变性梯度凝胶电泳(PCR-DGGE)及新一代测序技术(包括16S rRNA测序和宏基因组测序技术)的快速发展,肠道微生物作为一个“器官”越来越多地受到关注,相关研究进展突飞猛进。肠道微生物与肝移植术后感染、排斥反应等并发症存在相关性,通过干预肠道微生物可在一定程度上改善上述并发症。缺血性胆管病(IC)是肝移植后并发症的最严重类型,引起IC的原因包括缺血-再灌注损伤、免疫介导损伤及细胞毒性疏水性胆盐等。肠道微生物与上述IC的发病机制之间存在着紧密的联系,由此我们推测肠道微生物可能在肝移植术后IC的发生、发展中发挥重要作用。未来研究可能需着眼于肠道微生物预测IC的敏感性以及通过干预肠道菌群实现有效治疗。
Design and thermal analysis of a water-cooled DSC module

Elevated working temperatures reduce the efficiency of dye-sensitized solar cells (DSCs), and effective temperature regulation protects them from the undesirable efficiency loss. In this work, a semi-transparent DSC module equipped with a cooling system was designed and constructed for application in buildings, the temperature and output performance of the modules with or without cooling treatment were investigated. The test results showed the cooling system could noticeably improve the power generation and reduce the module temperature. Moreover, we established a mathematical model to analyze the modules’ thermal performances, and introduced the concept of cooling efficiency to evaluate the cooling effect. The model accuracy have been validated utilizing measured data, and the effects of channel depth and mass flow rate on the module temperature and cooling efficiency were further theoretically studied. The combined DSC module has been found to have a good application prospect in building integrated photovoltaic (BIPV), and the numerical results are important in system design.
Effect of treatment process on consolidation efficiency of fugitive dust cemented by bio-activated cementitious material based on CO_2 capture

As a new green and environmental material, bio-activated cementitious material is attracting extensive attention. This study confirmed that the bio-activated cementitious material could mineralize and cement fugitive dust into the calcite-consolidation-layer based on CO_2 capture and utilization. The results illustrated that treatment processes (non-pressure spraying, pressure spraying, non-pressure blending and pressure blending) had a strong effect on the microstructure and properties of calcite-consolidation-layer. According to the analysis of X-ray diffraction (XRD) and Fourier transform infrared(FTIR), calcite was prepared by bio-activated cementitious material during the cementation process. Meanwhile, scanning electron microscopy (SEM) and thermogravimetric-differential scanning calorimetry (TG-DSC) were adopted to measure the corresponding variation of porous characteristics and calcite content caused by different treatment processes. The results indicated that the microstructure of calcite-consolidation-layer from the spraying process had lower porosity and higher content of calcite than from blending processes. In addition, the mechanical properties of calcite-consolidation-layer were also tested. The hardness and compressive strength, which reached 19.5 GPa and 0.6 MPa, respectively, of calcite-consolidation-layer from the pressure spraying process were higher than those from the other three treatment processes. Compared with the non-treatment process, the four treatment processes had superior wind erosion resistance. Under the wind speed of 12 m/s, the mass loss of calcite-consolidation-layer from the pressure spraying process decreased from 2150.2 to 23.8 g/(m~2 h).
Facile synthesis of gold nanoflowers as SERS substrates and their morphological transformation induced by iodide ions

We report a new strategy to prepare gold nanoflowers (AuNFs) using a two-step seed-mediated method. The as-prepared AuNFs were employed as surface-enhance Raman scattering (SERS) substrates, showing strong signal enhancement. We further found that iodide ions (I~–) could selectively induce the morphological transformation of AuNFs to spheres, resulting in a blue-shift of the localized surface plasmon resonance (LSPR) bands, a color change of the AuNFs solution from blue to red, and decreased SERS activity. This behavior allows the AuNFs to be used in the determination of I~–.
Enhanced auditory evoked potentials in musicians: A review of recent findings

Auditory evoked potentials serve as an objective mode for assessment to check the functioning of the auditory system and neuroplasticity. Literature has reported enhanced electrophysiological responses in musicians, which shows neuroplasticity in musicians. Various databases including PubMed, Google, Google Scholar and Medline were searched for references related to auditory evoked potentials in musicians from 1994 till date. Different auditory evoked potentials in musicians have been summarized in the present article. The findings of various studies may support as evidences for music-induced neuroplasticity which can be used for the treatment of various clinical disorders. The search results showed enhanced auditory evoked potentials in musicians compared to non-musicians from brainstem to cortical levels. Also, the present review showed enhanced attentive and pre-attentive skills in musicians compared to non-musicians.
Type 2 diabetes, high blood pressure and acute pancreatitis

The incidence of acute pancreatitis is increasing, about 30-70 per 100 000 person-years in the Western world, with the highest rates in the United States, where diabetes and metabolic syndrome are common. Type 2 diabetes is a part of the metabolic syndrome, which is associated with a subsequent increased risk of cardiovascular disease. Several components of the metabolic syndrome have been reported to increase the risk of acute pancreatitis, including type 2 diabetes, obesity, dyslipidemia, and hypertension. We aimed to clarify the association between type 2 diabetes and acute pancreatitis. We also took conditions of the metabolic syndrome into account as that may have confounded the relationship reported in previous studies between type 2 diabetes and acute pancreatitis.

Effect of Fanbaicao (Herba Potentillae Discoloris) oil on the expression of p21 and CDK4 in HepG2 cells

OBJECTIVE: To research the anti-cancer mechanism of the Traditional Chinese Medicine Fanbaicao (Herba Potentillae Discoloris) oil in the human hepatoma cell line HepG2. METHODS: Gas chromatography was used to analyze the components of Fanbaicao (Herba Potentillae Discoloris). We tested the inhibitory effect of Fanbaicao (Herba Potentillae Discoloris) oil on the human hepatoma cell line HepG2 in vitro using 3-(4, 5-Dimet hylt hiazol-2-yl)-2,5-dip henyltetrazolium bromide assays. Fluorescence activating cell sorter analysis was used to examine the levels of apoptosis, and western blot and immunofluorescence were used to detect the expression of p21, p-p21 and CDK4 proteins. RESULTS: Fanbaicao (Herba Potentillae Discoloris) oil contains 45 ingredients, and L-ascorbic acid 2, 6-bispalmitate was the main component and accounted for 44.96% of total drive-off peak area. Other components included (Z)-14-met hyl-8-exadecenal-acetal (8.56%), phytol (7.74%) and lauric acid (6.31%). Fanbaicao (Herba Potentillae Discoloris) oil treatment reduced the proliferation of HepG2 cells and the half growth inhibition concentration (IC50) was 2.03 mg/mL. Furthermore, we also observed significantly increased HepG2 cell apoptosis in a dose-dependent manner (P < 0.05). Fanbaicao (Herba Potentillae Discoloris) oil significantly increased the expression of p21 and p-p21 and significantly decreased the expression of CDK4 in HepG2 cells compared with controls (P < 0.01). CONCLUSION: Our results showed that Fanbaicao (Herba Potentillae Discoloris) oil has anti-cancer activities in HepG2 cells, which is probably related to the upregulation of p21 and p-p21 and downregulation of CDK4 expression.
Joint relay selection and power control for robust cooperative multicast in mmWave WPANs

We propose an optimization algorithm for joint relay selection and source and relay power allocation under mixed line-of-sight (LoS) and non-LoS path scenarios for both power saving and robustness enhancement of cooperative multicast in millimeter-wave wireless personal area networks. Our aims are to reduce power consumption and enhance the robustness of cooperative multicasts in millimeter-wave wireless personal area networks. First, we describe a novel beam training protocol that is capable of overhearing and information feedback to filter relay candidates with non-LoS links and avoid selecting relays for transceivers with LoS paths. Second, the joint relay selection and power allocation issue is formulated as an optimization problem with the objective of minimizing the maximum combined power consumption of the source and relay under maximum tolerable outage probabilities and transmit powers. By introducing relaxation and Lagrange multiplier methods, a closed-form expression for the joint relay selection and power allocation is obtained. Finally, simulation results indicate significant improvements in terms of both outage probability and power consumption over the conventional combined transmit power minimization algorithm.

Heteronuclear Efimov resonances in ultracold quantum gases

The Efimov scenario is a universal three-body effect addressing many areas of modern quantum physics. It plays an important role in the transition between few- and many-body physics and has enabled important breakthroughs in the understanding of the universal few-body theory. We review the basic concepts of the Efimov scenario with specific emphasis on the similarities and differences between homonuclear and heteronuclear systems. In the latter scenario, the existence of a second, independently tunable interaction parameter enables novel few-body phenomena that are universal and have no counterexamples in the homonuclear case. We discuss recent experimental approaches using ultracold atomic gases with magnetically tunable interactions and elucidate the role of short-range interactions in the emergence of universal and non-universal behavior.
Development of polymer-fullerene solar cells

Global efforts and synergetic interdisciplinary collaborations on solution-processed bulk-heterojunction polymer solar cells (PSCs or OPVs) made power conversion efficiencies over 10% possible. The rapid progress of the field is credited to the synthesis of a large number of novel polymers with specially tunable optoelectronic properties, a better control over the nano-morphology of photoactive blend layers, the introduction of various effective interfacial layers, new device architectures and a deeper understanding of device physics. We will review the pioneering materials for polymer-fullerene solar cells and trace the progress of concepts driving their development. We discuss the evolution of morphology control, interfacial layers and device structures fully exploring the potential of photoactive materials. In order to guide a further increase in power conversion efficiency of OPV, the current understanding of the process of free charge carrier generation and the origin of the photovoltage is summarized followed by a perspective on how to overcome the limitations for industrializing PSCs.
SnO_2 nanospheres among GO and SWNTs networks as anode for enhanced lithium storage performances

Conducting supporters of purified single-walled carbon nanotubes (SWNTs) and graphene oxide (GO) were used to confine pomegranate-structured SnO_2 nanospheres for forming SnO_2-GO-SWNT composites. As anode material for lithium ion batteries (LIBs), this composite exhibits a stable and large reversible capacity together with an excellent rate capability. In addition, an analysis of the AC impedance spectroscopy has been used to confirm the enhanced mechanism for LIB performance. The improved electrochemical performance should be ascribed greatly to the reinforced synergistic effects between GO and SWNT networks, and their enhanced contribution of the conductivity. These results indicate that this composite has potential for utilization in high-rate and durable LIBs.
A review of design considerations in glass buildings

In the past few decades, the use of glass in buildings has remarkably increased. As a result, several transparent buildings have been constructed, in which the materials have almost disappeared. Given that the advancement of architecture is inextricably linked to the acquisition of general knowledge on future developments, this study was conducted to predict the paths of development that glass structures are likely to take in the future. Investigations such as this increase the possibility of advancing both design and construction at the same speed as technology. To achieve this goal, this study evaluates the present situation by investigating new possibilities and assessing their effect on the development of glass buildings. The findings of this study show that the durability, safety, appearance, and efficiency of transparent buildings can be improved through continuous refinement of designs, replacement of aged elements, prompt repair of damaged protective coatings, and greater exploitation of double-sided screens.
Chemical mapping of cement pastes by using confocal Raman spectroscopy

In the present study, chemical mapping on the hydration process of cement paste with water-to-cement (w/c) ratio of 0.60 was implemented by Raman spectroscopy (RS). The RS was applied to study the paste from 12 hours after mixing to 28 days. Cement ingredients and hydration products, including calcium silicates (C_3S and C_2S), calcium hydroxide (CH), and ettringite, were quantitatively studied. From the research, it is observed that calcium silicates were consumed gradually with the increased hydration age. Calcium hydroxide increased and tended to cluster in the pore vicinity during hydration. Ettringite was found to form on the surface of the unreacted particles, which was shown as a mixed zone of ettringite and calcium silicates in the maps. It is concluded from the study that chemical mapping was an effective method to assist in visualizing particle dispersion and connection on top of the quantitative analysis.
Choosing configurations of transmission line tower grounding by back flashover probability value

There is a considerable number of works devoted to electrical characteristics of grounding. These characteristics are important in general. However, in application to grounding of transmission line towers they are not enough to determine what grounding construction is preferable in some particular case, because these characteristics are calculated or measured apart from the grounded object, and only limited number of current (or voltage) source waveforms is used. This paper indicates reasons in favor of the fact that to choose the optimum design of grounding, the calculation model should include the tower as it is. The probability of back flashover, which provides both qualitative and quantitative estimate of the grounding structure efficiency, can be taken as the criterion for the grounding design. The insulation flashover probability is calculated on the basis of engineering method, which evaluates breakdown strength of insulation for nonstandard waveshapes, and probability data on lightning currents. Different approaches are examined for identifying the back flashover probability, as not only amplitudes but also other parameters can be taken into account. Finite-difference time-domain method is used for calculations of transients. It is found that lightning current waveform can greatly influence calculated back flashover probability value.
Performance enhancement of partially shaded solar PV array using novel shade dispersion technique

Solar photo voltaic array (SPVA) generates a smaller amount of power than the standard rating of the panel due to the partial shading effect. Since the modules of the arrays receive different solar irradiations, the P-V characteristics of photovoltaic (PV) arrays contain multiple peaks or local peaks. This paper presents an innovative method (magic square) in order to increase the generated power by configuring the modules of a shaded photovoltaic array. In this approach, the physical location of the modules in the total cross tied (TCT) connected in the solar PV array is rearranged based on the magic square arrangement pattern. This connection is done without altering any electrical configurations of the modules in the PV array. This method can distribute the shading effect over the entire PV array, without concentrating on any row of modules and can achieve global peaks. For different types of shading patterns, the output power of the solar PV array with the proposed magic square configuration is compared with the traditional configurations and the performance is calculated. This paper presents a new reconfiguration technique for solar PV arrays, which increases the PV power under different shading conditions. The proposed technique facilitates the distribution of the effect of shading over the entire array, thereby, reducing the mismatch losses caused by partial shading. The theoretical calculations are tested through simulations in Matlab/ Simulink to validate the results. A comparison of power loss for different types of topologies under different types of shading patterns for a 4 × 4 array is also explained.
The solubility of cefquinome sulfate in pure and mixed solvents

Solid-liquid equilibrium data of cefquinome sulfate is important to develop industrial crystallization processes for cefquinome sulfate. The solubilities of cefquinome sulfate in five pure solvents (methanol, ethanol, ethylene glycol, acetic acid and water) from 277.15 to 305.15 K and in a binary acetone-water solvent from 278.15 to 293.15 K were measured at atmospheric pressure. The pure-solvent solubility data was correlated to the modified Apelblat and Van't Hoff equations whereas the mixed-solvent system data was correlated to the modified Apelblat, Van't Hoff, CNIBS/R-K and Jouyban-Acree models. It was found that the solubilities of cefquinome sulfate in all tested solvents decreased with the increasing of temperature. In addition, the thermodynamic properties of the dissolution processes, including standard Gibbs free energy, enthalpy and entropy changes, were calculated using the Van't Hoff equation. It was found that the dissolution of cefquinome sulfate is exothermic.
Nucleic acid crystallization and X-ray crystallography facilitated by single selenium atom

X-ray crystallography is a powerful strategy for 3-D structure determination of macromolecules, such as nucleic acids and protein-nucleic acid complexes. However, the crystallization and phase determination are the major bottle-neck problems in crystallography. Recently we have successfully developed synthesis and strategy of selenium-derivatized nucleic acids (SeNA) for nucleic acid crystallography. SeNA might not only provide the rational strategies to solve the phase determination problem, but also offer a potential strategy to explore crystallization solutions.
An unconventional phase field modeling of domains formation and evolution in tetragonal ferroelectrics

Based on characteristic functions of variants, we developed an unconventional phase field modeling for investigating domains formation and evolution in tetragonal ferroelectrics. In order to develop this computational approach, we constructed the anisotropy energy of tetragonal variants, which is used instead of Landau-Devonshire potential in the conventional phase field method, resulting in that much fewer parameters are needed for simulations. This approach is advantageous in simulations of emerging ferroelectric materials. We employ it to study the formation and evolution of domains in tetragonal barium titanate single crystal, as well as the nonlinear behaviors under cyclical stress and electric field loading. A multi-rank laminated ferroelectric domain pattern, 90° domain switching accompanied by polarization rotation, and 180° domain switching accompanied by move of domain wall are predicted. It is found that the speed of 90° domain switching is slower than that of 180° domain switching, due to both polarization and transformation strain changed in 90° domain switching. It also suggests that large strain actuation can be generated in single crystal ferroelectrics via combined electromechanical loading inducing 90° domain switching. The good agreement between simulation results and experimental measurements is observed.
Lateral migration of dual droplet trains in a double spiral microchannel

Microfluidic droplets have emerged as novel platforms for chemical and biological applications. Manipulation of droplets has thus attracted increasing attention. Different from solid particles, deformable droplets cannot be efficiently controlled by inertia-driven approaches. Here, we report a study on the lateral migration of dual droplet trains in a double spiral microchannel at low Reynolds numbers. The dominant driving mechanism is elucidated as wall effect originated from the droplet deformation. Three types of migration modes are observed with varying Reynolds numbers and the size-dependent mode is intensively investigated. We obtain empirical formulas by relating the migration to Reynolds numbers and droplet sizes. The effect of droplet deformability on the migration and the detailed migration behavior along the double spiral channel are discussed. Numerical simulations are also performed and yielded in qualitative agreement with the experiments. This proposed low Re approach based on lateral migration could be a promising alternative to existing inertia-driven approaches especially concerning deformable entities and susceptible bio-particles.
