2A study of electron-shuttle mechanism in Klebsiella pneumoniae based-microbial fuel cells显示文摘In microbial fuel cell (MFC), the rate of electron transfer to anode electrode is a key intrinsic limiting factor on the power output of MFCs. Using Klebsiella pneumoniae (K. pneumoniae) strain L17 as biocatalyst, we studied the mechanism of electron shuttle via self-producing mediator in a cubic air-chamber MFC. To eliminate the influence of biofilm mechanism, the anode electrode was coated with microfiltration membrane (0.22 μm). Data showed that the microfiltration membrane coated and uncoated MFCs achieved the maximum voltage outputs of 316.2 and 426.2 mV after 270 and 120 h, respectively. When the medium was replaced in MFCs that had the highest power generation, the power output dropped by 62.1% and 8.8%, and required 120 and 48 h to resume the original level in the coated and uncoated MFCs, respectively. The results suggested an electron-shuttle mechanism rather than biofilm mechanism was responsible for electricity generation in the membrane coated MFC. Cyclic voltammetric measurements demonstrated the presence of an electrochemical active compound produced by K. pneumoniae strain L17, which was identified to be 2,6-di-tert-butyl-p-benzoquinon (2,6-DTBBQ) by GC-MS. 2,6-DTBBQ, as a recyclable electron shuttle, could transfer electrons between K. pneumoniae L17 and the anode electrode.DENG LiFang LI FangBai ZHOU ShunGui HUANG DeYin NI JinRen 2010Chinese Science Bulletin2010,55,1:9

4A New Species of the Genus Thermophis(Serpentes: Colubridae) from Shangri-La, Northern Yunnan, China, with a Proposal for an Eclectic Rule for Species Delimitation显示文摘The hot-spring snakes, Thermophis, were previously known only from the Tibet Autonomous Region and Western Sichuan, China. During the past two years, three adult hot-spring snakes(2 females, 1 male) were sampled in Shangri-La, northern Yunnan, China, thus expanding their known distribution region towards the southeast. This site is the southeastern-most corner of the Tibetan Plateau and the southernmost tip of the Hengduan Mountains(Mts.). Phylogenetic analysis of mitochondrial(mt) and nuclear(n) DNA segments suggested that the three specimens belong to the genus of Thermophis. Morphologically, the new species is more similar to T. zhaoermii. However, it is distinguished from T. zhaoermii in the number of maxillary teeth(15), distance between the two eyes/head width, rostral width/height, mental width/height, in one character limited to female: head width/length, and in four characters restricted to male: occurrence of the reduction from 10 to 8(8 to 6, 6 to 4) scales in each dorsal row on the tail. There are differences in morphology, genetics(mt DNA, n DNA), and geography between the putative new species and T. zhaoermii, the new species meets our proposed eclectic and feasible 'four-differences' rule.Lifang PENG Changhu LU Song HUANG Peng GUO Yaping ZHANG 2014Asian Herpetological Research2014,5,4:4
5Spatial Analysis of Commuting Mode Choice in Guangzhou, China显示文摘Metropolitan cities in China are commonly confronted with unresolved traffic congestion issues, primarily due to rapidly increasing traffic demand. Group disparity between commuting mode choice and its spatial distribution on road networks has enabled us to examine the factors that give rise to the discrepancies and the fundamental spatial causes of traffic congestion. In recent years, micro-perspective, individual, and behavior-based spatial analysis have mushroomed and been facilitated with effective tools such as temporal geographic information systems (T-GIS). It is difficult to study the interrelations between transport and space on the basis of commuting mode choice since the mode choice data are invisible in a specific space such as a particular road network. Therefore, in the field of transport, the classical origin destination (OD) four-stage model (FSM) is usually employed to calculate data when studying commuting mode choice. Based on the relative principles of T-GIS and the platform of ArcGIS, this paper considers Guangzhou as a case study and develops a spatio-temporal tool to examine the daily activities of residents. Meanwhile, the traffic volume distribution in rush hours, which was analyzed according to commuting modes and how they were reflected in the road network, was scrutinized with data extracted from travel diaries. Moreover, efforts were made to explain the relationship between traffic demand and urban spatial structure. Based on the investigation, this research indicates that traffic volumes in divergent groups and on the road networks is driven by: 1) the socio-economic characteristics of travelers; 2) a jobs-housing imbalance under suburbanization; 3) differences in the spatial supply of transport modes; 4) the remains of the Danwei (work unit) system and market development in China; and 5) the transition of urban spatial structure and other factors.ZHOU Suhong DENG Lifang HUANG Meiyu 2013Chinese Geographical Science2013,23,3:4
6Color-tunable ultralong organic phosphorescence materials for visual UV-light detection显示文摘Ultralong organic phosphorescence(UOP)materials have roused considerable attention in the field of photonics and optoelectronics owing to the feature of long-lived emission lifetimes.However,to develop UOP materials with color-tunability is still a formidable challenge.Here,we report a class of UOP materials containing carbonyl,amino or amide groups,exhibiting colortunable persistent luminescence ranging from blue(458 nm)to yellow-green(508 nm)under different UV wavelength excitation.Taken theoretical and experimental results together,we conclude that the excitation dependent color-tunable UOP emission is ascribed to multiple emission centers from single molecular and aggregated states in crystal.Given color-tunable UOP feature,these materials are used to successfully realize visual UV-light detection.This finding not only provides a strategy to design new organic phosphorescent molecules with colorful emission,but also extends the scope of the applications of purely organic phosphorescent materials.Lifang Bian Huili Ma Wenpeng Ye Anqi Lv He Wang Wenyong Jia Long Gu Huifang Shi Zhongfu An Wei Huang 2020Science China Chemistry2020,63,10:3
7Cytosolic delivery of the immunological adjuvant PolyⅠ:C and cytotoxic drug crystals via a carrier-free strategy significantly amplifies immune response显示文摘Co-delivery of chemotherapeutics and immunostimulant or chemoimmunotherapy is an emerging strategy in cancer therapy.The precise control of the targeting and release of agents is critical in this methodology.This article proposes the asynchronous release of the chemotherapeutic agents and immunostimulants to realize the synergistic effect between chemotherapy and immunotherapy.To obtain a proof-of-concept,a co-delivery system was prepared via a drug-delivering-drug(DDD)strategy for cytosolic co-delivery of Poly I:C,a synthetic ds RNA analog to activate RIG-I signaling,and PTX,a commonly used chemotherapeutics,in which pure PTX nanorods were sequentially coated with Poly I:C and mannuronic acid via stimulating the RIG-I signaling axis.The co-delivery system with a diameter of 200 nm enables profound immunogenicity of cancer cells,exhibiting increased secretion of cytokines and chemokines,pronounced immune response in vivo,and significant inhibition of tumor growth.Also,we found that intracellularly sustained release of cytotoxic agents could elicit the immunogenicity of cancer cells.Overall,the intracellular asynchronous release of chemotherapeutics and immunomodulators is a promising strategy to promote the immunogenicity of cancer cells and augment the antitumor immune response.Xiaoqing Du Yuqi Hou Jia Huang Yan Pang Chenlu Ruan Wei Wu Chenjie Xu Hongwei Zhang Lifang Yin Wei He 2021Acta Pharmaceutica Sinica B2021,11,10:3
8A New Species of the Genus Sinomicrurus Slowinski,Boundy and Lawson,2001 (Squamata:Elapidae) from Hainan Province,China显示文摘A new species of the coral snake genus Sinomicrurus is described based on four specimens from southern Hainan Island(three specimens from Tianchi,Jianfengling National Nature Reserve,one specimen from Diaoluoshan National Nature Reserve),Hainan Province,China.Morphologically,the new species is rather similar to Sinomicrurus kelloggi.However,it is distinct from S.kelloggi by the pattern on the head,the head length,head length/width,the number of infralabial scales,number of bands on dorsal body,and number of blotches on the belly.Lifang PENG Lijun WANG Li DING Yiwu ZHU Jian LUO Diancheng YANG Ruyi HUANG Shunqing LU Song HUANG 2018Asian Herpetological Research2018,9,2:3
9Distribution characteristics and its controlling factor of lacustrine high-quality source rocks in the Bozhong sag,Bohai Bay Basin显示文摘Distribution of Paleogene lacustrine high-quality source rocks in the Bozhong sag in Bohai Bay Basin is analyzed through data of geochemistry,geology and well logging,and its differences under the control of climate and tectonics is also well discussed.Distribution characteristics of the high-quality source rocks developed in the saline environment controlled by the climate are quite different from that developed in the rapid subsidence environment controlled by tectonics.The high-quality source rocks in Member 1 of Shahejie Formation developed in the saline environment account for 81.9%of total subsag area,and are distributed widely and extensively.The high-quality source rocks in Member 3 of Shahejie Formation and Member 3 of Dongying Formation is developed in the tectonic subsidence environment,and horizontally,the subsag subsidence rates has a positive correlation with the area proportion of the high-quality source rocks in the sag;vertically,the reduction-oxidation interface of the lake controls the enrichment of highquality source rocks.Controlled by the saline environment and rapid subsidence environment,the highquality source rocks in the Bozhong sag and adjacent areas have three types of development condition:the saline water,the tectonic subsidence,and joint control of the saline water and the tectonic subsidence.The humid climate and low subsidence rate are not favorable for development of high-quality source rocks.Hefeng Sun Lifang Liu Xue Jiang Shengbing Huang Mingyang Geng Shaoping Chen Nan Li Pu Shen 2019Petroleum Research2019,4,3:3
10A New Species of the Genus Achalinus from Huangshan, Anhui, China(Squamata: Xenodermidae)显示文摘A new species of the genus Achalinus is described based on five specimens collected from the villages of Huangjialing and Fuxi, Huangshan, Anhui, China. It can be morphologically differentia ted from all the other species in Achalinus except for A. spinalis and A. werneri by the presence of a dotted black streak in the middle of the subcaudal. It can be distinguished from A. spinalis in that its two anterior temporals are in contact with eye, and A. werneri by its light brown flanks. The phylogenetic rela tionship of Achalinus was reconstructed using the mitochondrial locus of cytochrome coxidase subunit 1(CO1). The five new specimens form a monophyletic clade with strong support. The uncorrected p-dista nces between the new species and other representatives of Achalinus range from 13.6% to 21.7%. The recognition of the new species increases the number of described Achalinus species to 14.Ruyi HUANG Lifang PENG Lei YU Tianqi HUANG Ke JIANG Li DING Jinkang CHANG Diancheng YANG Yuhao XU Song HUANG 2021Asian Herpetological Research2021,12,2:3
11Association of chromosome 7 aneuploidy measured by fluorescence in situ hybridization assay with muscular invasion in bladder cancer显示文摘Background:The preoperative prediction of muscular invasion status is important for adequately treating bladder cancer(BC)but nevertheless,there are some existing dilemmas in the current preoperative diagnostic accuracy of BC with muscular invasion.Here,we investigated the potential association between the fluorescence in situ hybridization(FISH)assay and muscular invasion among patients with BC.A cytogenetic-clinical nomogram for the individualized preoperative differentiation of muscle-invasive BC(MIBC)from non-muscle-invasive BC(NMIBC)is also proposed.Methods:All eligible BC patients were preoperatively tested using a FISH assay,which included 4 sites(chromosome-specific centromeric probe[CSP]3,7,and 17,and gene locus-specific probe[GLP]-p16 locus).The correlation between the FISH assay and BC muscular invasion was evaluated using the Chi-square tests.In the training set,univariate and multivariate logistic regression analyses were used to develop a cytogenetic-clinical nomogram for preoperative muscular invasion prediction.Then,we assessed the performance of the nomogram in the training set with respect to its discriminatory accuracy and calibration for predicting muscular invasion,and clinica usefulness,which were then validated in the validation set.Moreover,model comparison was set to evaluate the discrimination and clinical usefulness between the nomogram and the individual variables incorporated in the nomogram.Results:Muscular invasion was more prevalent in BC patients with positive CSP3,CSP7 and CSP17 status(OR[95%CI],2.724[1.555 to 4.774],P<0.001;3.406[1.912 to 6.068],P<0.001 and 2.483[1.436 to 4.292],P=0.001,respectively).Radiologydetermined tumor size,radiology-determined clinical tumor stage and CSP7 status were identified as independent risk factors of BC muscular invasion by the multivariate regression analysis in the training set.Then,a cytogenetic-clinical nomogram incorporating these three independent risk factors was constructed and was observed to have satisfactory discrimination in the training(AUC 0.784;95%CI:0.715 to 0.853)and validation(AUC 0.743;95%CI:0.635 to 0.850)set.The decision curve analysis(DCA)indicated the clinical usefulness of our nomogram.In models comparison,using the receiver operator characteristic(ROC)analyses,the nomogram showed higher discriminatory accuracy than any variables incorporated in the nomogram alone and the DCAs also identified the nomogram as possessing the highest net benefits at wide range of threshold probabilities.Conclusion:CSP7 status was identified as an independent factor for predicting muscular invasion in BC patients and was successfully incorporated in a clinical nomogram combining the results of the FISH assay with clinical risk factors.Xiayao Diao Jinhua Cai Junjiong Zheng Jianqiu Kong Shaoxu Wu Hao Yu Hao Huang Weibin Xie Xiong Chen Chengran Huang Lifang Huang Haide Qin Jian Huang Tianxin Lin 2020Cancer Communications2020,40,4:3
12Intraspecific Polymorphism of Rice Frog,Fejervarya multistriata(Anura: Ranidae),in Lingnan,Huangshan,China显示文摘Many anuran species exhibit striking color and/or pattern polymorphisms.We sampled 599 adult rice frogs,Fejervarya multistriata,from a rice paddy in the periphery of the Lingnan Nature Reserve(Huangshan,Anhui).We recognized ten morphs based on three relatively stable and distinct morphological characters: dorsal ground color(green or gray),middorsal stripe(absence,wide,or narrow),occipital rusty spot(absence or presence).The grey individuals are more common and larger than the green individuals(frequency 88.1 vs.11.9%,respectively) and(SVL 39.4–36.6 vs.35.7–34.6 mm,respectively).There is a higher proportion of individuals with a middorsal stripe(59.7%) while absence of the occipital rusty spot is more common in the population(82.3%).We expect additional studies in different habitat types would help build our understanding of the relationship between color polymorphism and habitat,geography,and climate.Diancheng YANG Lifang PENG Jingcheng XU Song HUANG 2017Asian Herpetological Research2017,18,1:2

14All-in-One Deposition to Synergistically Manipulate Perovskite Growth for High-Performance Solar Cell显示文摘Nonradiative recombination losses originating from crystallographic distortions and issues occurring upon interface formation are detrimental for the photovoltaic performance of perovskite solar cells.Herein,we incorporated a series of carbamide molecules(urea,biuret,or triuret)consisting of both Lewis base(-NH2)and Lewis acid(-C=O)groups into the perovskite precursor to simultaneously eliminate the bulk and interface defects.Depending on the different coordination ability with perovskite component,the incorporated molecules can either modify crystallization dynamics allowing for large crystal growth at low temperature(60℃),associate with antisite or undercoordinated ions for defect passivation,or accumulate at the surface as an energy cascade layer to enhance charge transfer,respectively.Synergistic benefits of the above functions can be obtained by rationally optimizing additive combinations in an all-in-one deposition method.As a result,a champion efficiency of 21.6%with prolonged operational stability was achieved in an inverted MAPbI3 perovskite solar cell by combining biuret and triuret additives.The simplified all-in-one fabrication procedure,adaptable to different types of perovskites in terms of pure MAPbI3,mixed perovskite,and all-inorganic perovskite,provides a cost-efficient and reproducible way to obtain high-performance inverted perovskite solar cells.Yifan Lv Hui Zhang Jinpei Wang Libao Chen Lifang Bian Zhongfu An Zongyao Qian Guoqi Ren Jie Wu Frank Nuesch Wei Huang 2020Research2020,,1:2

18Regioisomerism effect(RIE) on optimizing ultralong organic phosphorescence lifetimes显示文摘Organic phosphorescence materials demonstrate potential optoelectronic applications due to their remarkably ultralong organic phosphorescence(UOP)lifetime and abundant optical characteristics prior to the fluorescence materials.For a better insight into the intrinsic relationship among regioisomeric molecules,crystalline interactions,and phosphorescence properties,three crystalline dicarbazol-9-yl pyrazine-based regioisomers with para-,meta-and ortho-convergent substitutions(p-DCzP,m-DCzP,and o-DCzP)were designed and presented gradually increased UOP lifetimes prolonging from 63.14,127.93 to 350.46 ms,respectively,due to the regioisomerism effect(RIE)which would be an effective strategy for better understanding of structure-property of UOP materials.Yanni Zhang Jianfeng Zhao Caixia Zhu Lifang Bian Huifang Shi Shiming Zhang Huili Ma Wei Huang 2019Chinese Chemical Letters2019,30,11:1
