4Value of a newly sequenced bacterial genome显示文摘Next-generation sequencing(NGS) technologies have made high-throughput sequencing available to medium- and small-size laboratories, culminating in a tidal wave of genomic information. The quantity of sequenced bacterial genomes has not only brought excitement to the field of genomics but also heightened expectations that NGS would boost antibacterial discovery and vaccine development. Although many possible drug and vaccine targets have been discovered, the success rate of genome-based analysis has remained below expectations. Furthermore, NGS has had consequences for genome quality, resulting in an exponential increase in draft(partial data) genome deposits in public databases. If no further interests are expressed for a particular bacterial genome, it is more likely that the sequencing of its genome will be limited to a draft stage, and the painstaking tasks of completing the sequencing of its genome and annotation will not be undertaken. It is important to know what is lost when we settle for a draft genome and to determine the 'scientific value' of a newly sequenced genome. This review addresses the expected impact of newly sequenced genomes on antibacterial discovery and vaccinology. Also, it discusses the factors that could be leading to the increase in the number of draft deposits and the consequent loss of relevant biological information.Eudes GV Barbosa Flavia F Aburjaile Rommel TJ Ramos Adriana R Carneiro Yves Le Loir Jan Baumbach Anderson Miyoshi Artur Silva Vasco Azevedo 2014World Journal of Biological Chemistry2014,5,2:7
5A Statistical Study on Seismo-Ionospheric Anomalies of the Total Electron Content for the Period of 56 M≥6.0 Earthquakes Occurring in China During 1998—2012显示文摘This paper reports statistical results of Seismo-Ionospheric Anomalies(SIAs) of the Total Electron Content(TEC) in the Global Ionosphere Map(GIM) associated with 56 M≥6.0 earthquakes in China during 1998—2012.To detect SIA,a quartile-based(i.e.median-based) process is performed.TEC anomalies for the period of earthquakes without being led by magnetic storms about 10 days are further isolated and examined to confirm the SIP existence.Results show that SIA is the TEC significantly decrease in the afternoon period 2—9 days before the earthquakes in China,which is in a good agreement with the SIA appearing before the 12 May 2008 M 8.0 Wenchuan earthquake.Liu J Y Chen C H Tsai H F Le H 2013空间科学学报2013,33,3:7
6Genetic diversity of the hepatitis C virus: Impact and issues inthe antiviral therapy显示文摘The hepatitis C Virus (HCV) presents a high degree of genetic variability which is explained by the combination of a lack of proof reading by the RNA dependant RNA polymerase and a high level of viral replication. The re- sulting genetic polymorphism defines a classification in clades, genotypes, subtypes, isolates and quasispecies. This diversity is known to reflect the range of responses to Interferon therapy. The genotype is one of the pre- dictive parameters currently used to define the antiviral treatment strategy and the chance of therapeutic suc- cess. Studies have also reported the potential impact of the viral genetic polymorphism in the outcome of antivi- ral therapy in patients infected by the same HCV geno- type. Both structural and non structural genomic regions of HCV have been suggested to be involved in the Inter- feron pathway and the resistance to antiviral therapy. In this review, we first detail the viral basis of HCV diversity. Then, the HCV genetic regions that may be implicated in resistance to therapy are described, with a focus on the structural region encoded by the E2 gene and the non- structural genes NS3, NS5A and NS5B. Both mechanisms of the Interferon resistance and of the new antiviral drugs are described in this review.H Le Guillou-Guillemette S Vallet C Gaudy-Graffin C Payan A Pivert A Goudeau F Lunel-Fabiani 2007World Journal of Gastroenterology2007,13,17:6
7Phosphorus fractions and sorption dynamics in the sediments of two Ca-SO4 water reservoirs in the central Argentine Andes显示文摘Phosphorus(P) fractionation and sorption behavior were studied in the sediments of two calcium-sulfate(Ca-SO_4: Ca^(2+)170 mg L^(-1); SO_4^(2-) 400 mg L^(-1)) water reservoirs in the southern central Argentine Andes-El Carrizal Reservoir(ECR),which stratifies in summer and El Nihuil Reservoir(ENR),which is vertically mixed throughout the year. Sediment size classes reflected the lithology of both basins and the reservoirs relative location: ECR(downstream from a valley adjacent to a mountain environment) had higher clay proportions while the sand fraction was more important in ENR(just next to a mountain environment).In both reservoirs, the chemical composition revealed low alteration and calcium enrichment. Total P content was relatively high(1.1-1.6 mg P kg^(-1) dry weight) as expected from the contribution of marine formations. P fractionation was dominated by Ca-P(ECR, 69% and ENR, 63%) followed by organic-P(23%)in summer-anoxic ECR and by iron/aluminum(Fe/Al)-P(27%) in oxic ENR. Batch experiments showed that sorption behavior in ECR had a typical Langmuir isotherm plot while in ENR that model fitted only at low dissolved P values(<5 mg PL^(-1)) and co-precipitation evidence was observed at higher P concentrations. It is proposed that lower Fe/Al-P content in anoxic(ECR) vs. oxic(ENR) sediments results from the P released from iron-bound phosphorus due to sulfate reduction-ferrous sulfide formation in an anoxic environment. This condition should enable ECR sediments to adsorb P into fresh oxidized iron,and ENR sediments to co-precipitate P with calcium due to Fe/Al-P saturation, as observed in batch experiments. This paper constitutes the first description of phosphorus content and dynamics in reservoir sediments in arid central western Argentina, where water sulfate concentrations are naturally high due to basin lithology.José Gabriel León Fernando Luis Pedrozo Pedro Félix Temporetti 2017International Journal of Sediment Research2017,32,3:3

12胚胎巨噬细胞和小胶质细胞消融调控小鼠胚胎背根神经节感觉神经元的发育显示文摘众所周知,小胶质细胞可以调节中枢神经系统发育的一些方面。在第11.5天的小鼠胚胎中的小胶质细胞定殖脊髓时,它们与背根神经节感觉神经元(SN)的生长中心轴突相互作用,这表明它们可能在SN发育中发挥一定功能。为了解决这个问题,我们使用缺乏胚胎巨噬细胞(PU.1敲除小鼠)和免疫细胞消融的小鼠胚胎分析胚胎巨噬细胞消融对SNs早期发育的影响。我们发现,除小胶质细胞外,胚胎巨噬细胞还与来自第11.5天的小鼠胚胎的原肌球蛋白受体激酶(Trk)C+感觉神经元,TrkB+感觉神经元和TrkA+感觉神经元外周神经突产生交联。免疫细胞剥夺会导致第11.5天的小鼠胚胎的TrkC+感觉神经元和TrkB+感觉神经元初始数量的减少,这与其发育细胞死亡(DCD)的改变有关联的可能性较小,因为其后在第12.5天的胚胎中的数量有短暂增加。在分析的发育期(第11.5~15.5天),它也导致TrkA+感觉神经元数量减少,尽管我们没有观察到他们的DCD有任何变化。与神经元祖细胞可能存在一致性的脑脂肪酸结合蛋白(BFABP-)阴性细胞的增殖在第11.5天的胚胎中增加,而它们的增殖在第12.5天的胚胎减少,这可部分解释从11.5 d观察到的SN亚型产生的改变。此外,我们观察到在缺乏胚胎巨噬细胞的情况下神经胶质细胞祖细胞(BFABP+细胞)增殖的改变。我们的数据表明,胚胎巨噬细胞和小胶质细胞消融调控SN的发育。Angelim MKSC Maia LMSS Mouffle C Ginhoux F Low D Amancio-Dos-Santos A Makhoul J Le Corronc H Mangin JM Legendre P 聂昊(编译) 2018神经损伤与功能重建2018,13,9:2
13神经病理性疼痛的新机制:脊髓背角氯离子失衡导致5-HT下行抑制作用转变为易化作用显示文摘急性痛对机体具有保护作用。过度疼痛激活内源性镇痛系统,从而有效控制疼痛。内源性痛觉调制系统如何参与神经病理性疼痛,近年来备受关注。法国波尔多大学的研究者发现:神经损伤引起脊髓背角氯离子失衡,导致内源性5-HT系统由下行抑制转变为下行易化,进而诱导神经病理性疼痛。第一部分研究主要在正常小鼠上进行,发现RMg的5-HT能神经元投射到脊髓背角,产生内源性镇痛作用(既发挥下行抑制的作用)。刘风雨(译) Aby F Lorenzo LE Grivet Z 2022中国疼痛医学杂志2022,28,9:2
1425 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits.DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN 2019Photonics Research2019,7,4:2
15Competition between fusion-evaporation and multifragmentation in central collisions in ^(58)Ni+^(48)Ca at 25A MeV显示文摘The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the Fermi energy domain.As a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy tensor.For the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been constructed.The main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their correlations.Much emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear system.Dynamical evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport theories.Different approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMFs close to the heavy residues.Possible deviations from sequential processes were found for those IMFs in the region of masses intermediate between the mass of heavy residues and the mass of light IMFs.Further simulations are in progress.The experimental analysis will be enriched also by information obtained inspecting the IMF-IMF correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having the largest IMF multiplicity.FRANCALANZA L ABBONDANNO U AMORINI F BARLINI S BINI M BOUGAULT R BRUNO M CARDELLA G CASINI G AGOSTINO M D' De FILIPPO V De SANCTIS J GERACI E GIUSSANI A GRAMEGNA F GUIOT B KRAVCHUK V La GUIDARA E LANZALONE G Le NEINDRE N MAIOLINO C MARINI P MORELLI L OLMI A PAGANO A PAPA M PIANTELLI S PIRRONE S POLITI G POGGI G PORTO F RUSSOTTO P RIZZO F VANNINI G VANNUCCI L 2013Nuclear Science and Techniques2013,24,5:2
