1Two-photon-excited near-infrared emissive carbon dotsas multifunctional agents for fluorescence imaging andphotothermal therapy显示文摘C dots (CDs) have shown great potential in bioimaging and phototherapy.However, it is challenging to manipulate their fluorescent properties andtherapeutic efficacy to satisfy the requirements for clinic applications. In thisstudy, we prepared S, Se-codoped CDs via a hydrothermal method anddemonstrated that the doping resulted in excitation wavelength-independentnear-infrared (NIR) emissions of the CDs, with peaks at 731 and 820 nm.Significantly, the CDs exhibited a photothermal conversion efficiency of -58.2%,which is the highest reported value for C nanostructures and is comparable tothat of Au nanostructures. Moreover, the CDs had a large two-photon absorptioncross section (-30,045 GM), which allowed NIR emissions and the photothermalconversion of the CDs through the two-photon excitation (TPE) mechanism. Invitro and in vivo tests suggested that CDs can function as new multi functionalphototheranostic agents for the TPE fluorescence imaging and photothermaltheraov of cancer cells.Minhuan Lan Shaojing Zhao Zhenyu Zhang Li Yan Liang Guo Guangle Niu Jinfeng Zhang Junfang Zhao Hongyan Zhang Pengfei Wang Guangyu Zhu Chun-Sing Lee Wenjun Zhang 2017Nano Research2017,10,9:9
2On the number of rotation symmetric Boolean functions显示文摘Rotation symmetric Boolean functions (RSBFs) have been used as components of different cryptosystems. This class of functions are invariant under circular translation of indices. In this paper, we investigated balanced RSBFs and 1st order correlation immune RSBFs. Based on constructive techniques, we give an accurate enumeration formula for n-variable balanced RSBFs when n is a power of a prime. Furthermore, an original and efficient method to enumerate all n-variable (n prime) 1st order correlationimmune functions is presented. The exact number of 1st order correlation immune RSBFs with 11 variables is 6925047156550478825225250374129764511077684773805520800 and the number of 13 variables has 189 digits. Then for more variables, we also provide a significant lower bound on the number of 1st order correlation immune RSBFs.FU ShaoJing LI Chao QU LongJiang 2010Science China(Information Sciences)2010,53,3:8
3Immunocytological evidence for the presence of vertebrate FSH and LH-like substances in the brain and thoracic ganglion of the swimming crab,Portunus trituberculatus显示文摘调查在游泳螃蟹刺激荷尔蒙(FSH ) 和 luteinizing (LH ) 的滤泡的分发, Portunus trituberculatus,在它的繁殖规定机制的理解的帮助。这研究与免疫在大脑和胸的中心团检测了脊椎动物象 FSH 一样和象 LH 一样物质的地点细胞化学的技术。他们的免疫反应在不成熟的时期和 spawning 以后时期期间很弱或否定,当它在成熟时期是更强壮的时。象 FSH 一样免疫的本地化反应房间类似于象 LH 一样房间的。这些免疫反应房间在 protocerebrum 的前面的中部的房间簇主要被观察,更强壮的免疫染色。仅仅在有一些向内 deutocerebrum 的嗅觉的脑叶的房间簇和 tritocerebrum 的以后的房间簇。Immunoreactive 房间位于都,三在胸的中心团中轧了神经胶质。这些结果显示类似于脊椎动物 FSH 和 LH 的物质在 P 存在。trituberculatus,和他们的表示与卵巢的发展阶段有某关联,因此,他们可能从事卵巢发展和排卵。Huiyang Huang Haihui Ye Shaojing Li Guizhong Wang 2008Progress in Natural Science:Materials International2008,18,11:4
4Impacts of CO_2-driven seawater acidification on survival,egg production rate and hatching success of four marine copepods显示文摘Ecological experiments were conducted to examine the effects of seawater containing elevated par- tial pressure of carbon dioxide (p CO2 800 × 10 -6 , 2 000 × 10 -6 , 5 000 × 10 -6 and 10 000 × 10 -6 ) on the survival and reproduction of female Acartia pacifica, Acartia spinicauda, Calanus sinicus and Centropages tenuiremis, which are the dominant copepods in the southern coastal waters of China. The results show that the effects of elevated p CO2 on the survival rates of copepods were species-specific. C. sinicus, which was a macro-copepod, had a higher survival rate (62.01%-71.96%) than the other three species (5.00%-26.67%) during the eight day exposure. The egg production rates of C. sinicus, A. spinicauda and C. tenuiremis were significantly inhibited by the increased p CO2 and the exposure time duration. There were significantly negative impacts on the egg hatching success of A. spinicauda and C. tenuiremis in the p CO2 2 000 × 10 -6 and 10 000 × 10 -6 groups, and, in addition, the exposure time had noticeably impacts on these rates too. This study indicates that the reproductive performances of copepods were sensitive to elevated p CO2 , and that the response of different copepod species to acidified seawater was different. Furthermore, the synergistic effects of seawater acidification and climate change or other pollutant stresses on organisms should be given more attention.ZHANG Dajuan LI Shaojing WANG Guizhong GUO Donghui 2011Acta Oceanologica Sinica2011,30,6:4
5Chemical induction of settlement and metamorphosis in two Babylonia (Gastropoda) larvae显示文摘By exposure to 12 x 10 3 mol/dm3 K+ for 24 h, more than 90% of planktonic larvae of Babylonia formosae and B. areolata were effectively induced to metamorphose completely. 15 x 10 - 3 mol/dm3 K+ exerted toxic effect on larval B. areolata over a 24-h period, but produced better results of induction by 12 h exposure. Metamorphosed juveniles induced by increased by K’ could move and feed normally. Percent metamorphosis increased with average shell height for K + -induced larvae. L-DOPA, epinephrine and norepinephrine ranging from 5. 5 x 10 -- 6 to 5. 5 x 10 - 5 mol/dm3 had no inductive activity to metamorphosis in larval B. areolata, whereas the rate of metamorphosis induced by dopamine at a concentration of 10--4 mol/dm3 was approximately half less than that by 12 x 10 3 mol/dm3 K+. TEA (a K+ -channel blocker) did not inhibit metamorphosis in the two Babylonia larvae by induction of K+. Based on the results of K+ -induced experiments, it is preliminarily suggested that shell height of larvae achieving metamorphic competence was in the range of 860. 2 - 1 009. 8μm for B. formosae, and 849. 6- 956. 0 um for B. areolata. In addition, planktonic larvae of the two Babylonia had delayed metamorphosis.Ke Caihuan Li Shaojing Li Fuxue Zheng Zhon Liu Weibin (1.

6Settlement and metamorphosis of Styela canopus Savigny larvae in response to some neurotransmitters and thyroxin显示文摘The larvae of ascidian Styela canopus Savigny were treated with epinephrine, norepinephrine, L-DOPA, GABA and thyroxin to test the ability of these compounds to induce or inhibit larval settlement and metamorphosis. The results showed that epinephrine, norepinephrine and L-DOPA at the concentration of 1μmol/dm 3 induced larval settlement and metamorphosis in S. canopus, with short exposure (1 h) to 1 μmol/dm 3 of L-DOPA inducing rapid settlement. In contrast, GABA at the concentrations of 0.1 ~100.0 μmol/dm 3 significantly inhibited the settlement and metamorphosis of S. canopus larvae. In addition, thyroxin at 1~50 μg/dm 3 had no effect on larval settlement and metamorphosis in S. canopus. These results suggest the importance of neurotransmitters in the settlement and metamorphosis of S. canopus larvae.FENG Danqing HUANG Ying KE Caihuan ZHOU Shiqiang LI Shaojing 2006Acta Oceanologica Sinica2006,25,3:3
7Occurrence of gonadtropins like substance in the thoracic ganglion mass of the mud crab, Scylla paramamosain (Crustacea: Decapoda: Brachyura)显示文摘The identification and localization of vertebrate follicle stimulating hormone (FSH) and luteinizing hormone (LH) in crustaceans may further elucidate the regulation mechanisms in arthropod repro-duction. Using immunocytochemical staining techniques, this study has localized vertebrate FSH-like and LH-like substances in neurons in the subesophageal and thoracic ganglia from the thoracic ganglion mass (TGM) of Scylla paramamosain (Crustacea: Decapoda: Brachyura). Enzyme-linked immunosorbent assay (ELISA) has shown that the concentrations of both FSH-and LH-like sub-stances increased markedly in the TGM during the vitellogenic stage compared with that in the previtellogenic stage. These results indicate that substances resembling the vertebrate FSH and LH are present in S. paramamosain, and they may be involved in the development of the ovary as well as in ovulation.YE Haihui HUANG Huiyang WANG Guizhong LI Shaojing 2009Acta Oceanologica Sinica2009,28,5:3
8A Single-cell Transcriptome Atlas of Cashmere Goat Hair Follicle Morphogenesis显示文摘Cashmere,also known as soft gold,is produced from the secondary hair follicles(SHFs)of cashmere goats.The number of SHFs determines the yield and quality of cashmere;therefore,it is of interest to investigate the transcriptional profiles present during cashmere goat hair follicle development.However,mechanisms underlying this development process remain largely unexplored,and studies regarding hair follicle development mostly use a murine research model.In this study,to provide a comprehensive understanding of cellular heterogeneity and cell fate decisions,single-cell RNA sequencing was performed on 19,705 single cells of the dorsal skin from cashmere goat fetuses at induction(embryonic day 60;E60),organogenesis(E90),and cytodifferentiation(E120)stages.For the first time,unsupervised clustering analysis identified 16 cell clusters,and their corresponding cell types were also characterized.Based on lineage inference,a detailed molecular landscape was revealed along the dermal and epidermal cell lineage developmental pathways.Notably,our current data also confirmed the heterogeneity of dermal papillae from different hair follicle types,which was further validated by immunofluorescence analysis.The current study identifies different biomarkers during cashmere goat hair follicle development and has implications for cashmere goat breeding in the future.Wei Ge Weidong Zhang Yuelang Zhang Yujie Zheng Fang Li Shanhe Wang Jinwang Liu Shaojing Tan Zihui Yan Lu Wang Wei Shen Lei Qu Xin Wang 2021Genomics, Proteomics & Bioinformatics2021,19,3:3
9A preliminary study of the variation of phytoplankton absorption coefficients in the northern South China Sea显示文摘The temporal and spatial variabilities of phytoplankton absorption coefficients (a ph (λ)) and their relationships with physical processes in the northern South China Sea were examined, based on in situ data collected from two cruise surveys during May 14 to 25, 2001 and November 2 to 21, 2002. Significant changes in the surface water in a ph values and B/R ratios (a ph (440)/a ph (675)) were observed in May, which were caused by a phytoplankton bloom on the inner shelf stimulated by a large river plume due to heavy precipitation. This is consistent with the observed one order of magnitude elevation of chlorophyll a and a shift from a pico/nano dominated phytoplankton community to one dominated by micro-algae. Enhanced vertical mixing due to strengthened northeast monsoon in November has been observed to result in higher surface a ph (675) (0.002–0.006 m-1 higher) and less pronounced subsurface maximum on the outer shelf/slope in November as compared with that in May. Measurements of a ph and B/R ratios from three transects in November revealed a highest surface a ph (675) immediately outside the mouth of the Zhujiang (Pearl) River Estuary, whereas lower a ph (675) and higher B/R ratios were featured in the outer shelf/slope waters, demonstrating the respective influence of the Zhujiang River plume and the oligotrophic water of the South China Sea. The difference in spectral shapes of phytoplankton absorption (measured by B/R ratios and bathochromic shifts) on these three transects infers that picoprocaryotes are the major component of the phytoplankton community on the outer shelf/slope rather than on the inner shelf. A regional tuning of the phytoplankton absorption spectral model (Carder et al., 1999) was attempted, demonstrating a greater spatial variation than temporal variation in the lead parameter a 0 (λ). It was thus implicated that region-based parameterization of ocean color remote sensing algorithms in the northern South China Sea was mandatory.WU Jingyu HONG Huasheng SHANG Shaoling DAI Minhan LEE Zhongping LI Shaojing 2009Acta Oceanologica Sinica2009,28,5:2
10Effects of biogenic amines on the testicular development in mud crabs Scylla serrata显示文摘The regulation of three biogenic amines over the reproductive neuroendocrine activity of the male Scylla serrata was investigated by in vivo injection and in vitro incubation. The testicular index, the ratio of the mature sections in testes, and the ratio of Type B cells in androgenic gland were taken as the quantitative indexes. The in vivo injections indicated that: 5-HT can significantly promote the testicular development and the secretion of the androgenic gland in S. serrata; DA can inhibit the testicular development, but no influence on the secretion of the androgenic gland was found; no significant difference was observed between the OA-injected group and the concurrent control group. In vitro incubations showed that: 5-HT can stimulate the secretion of the brain and the thoracic ganglia, thus accelerating that of the androgenic gland; however, neither OA nor DA showed any significant influence on the secretion of the brain and the thoracic ganglionic mass. As to the optic ganglia, the three biogenic amines hardly have any effect on its secretion. It is the first time to report the regulation of biogenic amines over the reproductive neuroendocrine of male crustaceans through vitro experiments. Results corroborate that 5-HT activates the brain and the thoracic ganglia to secret GSH first, then promote the testicular development through the activity of the androgenic gland.YE Haihui HUANG Huiyang LI Shaojing WANG Guizhong LI Qifu 2006Acta Oceanologica Sinica2006,25,2:2
11The Existence of a Class of Balanced Multi-output Rotation Symmetric Boolean Functions显示文摘A new characterization of balanced rotation symmetric(n, m)-functions is presented. Based on the characterization, the nonexistence of balanced rotation symmetric(p^r, m)-functions is determined, where p is an odd prime and m ≥ 2. And there exist balanced rotation symmetric(2~r, m)-functions for 2 ≤ m ≤ 2~r-r. With the help of these results, we also prove that there exist rotation symmetric resilient(2~r, m)-functions for 2 ≤ m ≤ 2~r-r-1.DU Jiao FU Shaojing QU Longjiang LI Chao PANG Shanqi 2018Chinese Journal of Electronics2018,27,5:2
12Immunorecognition of estrogen and androgen receptors in the brain and thoracic ganglion mass of mud crab,Scylla paramamosain显示文摘The brain and the thoracic ganglion of a crustacean can synthesize and secrete gonad-stimulating hormone(GSH)which stimulates the maturation of gonad.In the previous experiments,sex steroid hormones(estradiol,testosterone,progesterone,etc.)have been detected from the crustacean.However,the feedback regulation of sex steroid hormones on the brain and the thoracic ganglion of the crustacean has not been reported so far.In the present experiment,monoclonal antibodies were applied to investigate the immuno-recognition of estrogen receptor(ER)and androgen receptor(AR)in the brain and the thoracic ganglion mass of Scylla paramamosain.The results showed that the distribution of the immunopositive substances of ER and AR was extremely similar.They distributed in the protocerebrum,deutocerebrum and tritocerebrum of the brain,and mainly in protocerebrum.In the thoracic ganglion mass,immuno-positive substances distributed in the subesophageal ganglion,thoracic ganglion and abdominal ganglion,and mostly in subesophageal ganglion.Immunopositive substances of ER and AR mostly existed in the cytoplasm of neurons.The present study will provide mor-phological evidence for the origin and the evolution of ER and AR.In addition,the immunoreactivities of ER and AR suggested that the estrogen and androgen may be involved in the feedback regulation of crustacean neuroendocrine.Haihui Ye Huiyang Huang Shaojing Li Guizhong Wang 2008Progress in Natural Science:Materials International2008,18,6:2
13Aequorea taiwanensis n. sp. (Hydrozoa,Leptomedusae) and mtCOI sequence analysis for the genus Aequorea显示文摘Aequorea taiwanensis,a new hydrozoan species from the Taiwan Strait was described using morphological and molecular characteristics.Both morphological and mitochondrial cytochrome oxidase subunit I(mtCOI) data supported A.taiwanensis n.sp.as a valid species.Sequence divergence and genetic distance of A.taiwanensis n.sp.,A.papillata and A.conica were analysed based on the mtCOI gene sequences.The mtCOI sequences from these three species of the genus Aequorea showed high variation frequency,with sequence divergences ranging from 9.10% to 11.9%,and pairwise genetic distances ranging from 0.097 to 0.130.MtCOI sequence analysis provided diagnostic molecular systematic characteristics for accurate identification and discrimination of the species of Aequorea or their populations,and will be used to resolve evolutionary relationships among them.It was suggested that 10%-20% pairwise mtCOI sequence differences indicated the species-level divergence among congeneric species in the Hydromedusae.ZHENG Lianming LIN Yuanshao LI Shaojing CAO Wenqing XU Zhenzu HUANG Jiaqi 2009Acta Oceanologica Sinica2009,28,1:2
14Genetic diversity and differentiation of three populations of Penaeus monodon Fabricus显示文摘Genetic diversity of two wild Penaeus monodon populations sampled from the coastal waters of Qinglan (Hainan Province of China,HN) and Malaysia (KD),and the F1 generation of a Thailand broodstock population (CP) were examined by vertical polyacrylamide gel electrophoresis. Of 21 loci encoded by ten enzymes,11 were polymorphic. The mean proportions of polymorphic loci of HN,KD and CP were 36.36%,45.45% and 50.00%,with the average heterozygosities of 0.135,0.181 and 0.191,and the effective numbers of alleles per loci were 1.300,1.330 and 1.329,respectively. The divergent indexes of HN,KD and CP were 0.023,0.124,and 0.117,respectively. The genetic distance between the two wild populations was 0.005,and the gene differentiation coefficient was also very low (0.014). The results indicated that the F1 generation population had a higher genetic diversity than the two wild populations,and that the HN population had the lowest one. There was no significant differentiation between HN and KD populations and all populations existed with a slight heterozygote excess.WANG Guizhong TAN Shuhua LI shaojing YE Haihui 2008Acta Oceanologica Sinica2008,27,1:2

16Construction of even-variable rotation symmetric Boolean functions with maximum algebraic immunity显示文摘Rotation symmetric Boolean functions(RSBFs) have been used as components of different cryptosystems.In this paper,we investigate n-variable(n even and n≥12) RSBFs to achieve maximum algebraic immunity(AI),and provide a construction of RSBFs with maximum AI and nonlinearity.These functions have higher nonlinearity than the previously known nonlinearity of RSBFs with maximum AI.We also prove that our construction provides high algebraic degree in some case.FU ShaoJing LI Chao MATSUURA Kanta QU LongJiang 2013Science China(Information Sciences)2013,56,3:2

19Green synthesis of multifunctional carbon dots for anti-cancer and anti-fungal applications显示文摘Carbon dots(CDs)have become popular nanomaterials in biomedical and agricultural fields.Herein we synthesized multifunctional CDs which showed anti-cancer and anti-fungal activities.The low cytotoxicity,stable fluorescence and high photothermal conversion efficiency enable the CDs with imagingguided photothermal therapy.The CDs also exhibited intrinsic anti-fungal activity even at a low concentration,i.e.,40 mg·L^(-1) of CDs induced 20%mortality in cucumber downy mildew.Moreover,the largeπ-conjugated nanostructure and the richness of amino and hydroxyl groups make them a powerful delivery platform for flumorph(a fungicide)with a high loading efficiency of 47.18%.Meanwhile,the heat converted from the light can accelerate the release of flumorph from CDs,and thus efficiently kill fungus.Shaojing Zhao Li Huang Yong Xie Bin Wang Feng Wang Minhuan Lan 2021Chinese Journal of Chemical Engineering2021,34,9:1
20Preliminary study of the retention mechanism of planktonic copepods in the Jiulong Estuary in China显示文摘The horizontal and vertical distribution patterns of five planktonic copepods,Calanus sinicus, Acartia pacifica, Tortanus derjugini, Acartiella sinensis and Pseudodiaptomus poplesia, predominant in the Jiulong Estuary, were investigated from May 2003 to April 2004. The results showed that the distribution of these copepods was related to the tidal period but that each species had its own specific pattern. C. sinicus showed no tidal vertical migration behavior and was thought to be a non-resident species in this estuary. Among Acartia pacifica,T. derjugini,Acartiella sinensis, more individuals occurred in the surface than in the bottom waters during flood tide, and the pattern was reversed during ebb tide. The epibenthic copepod P. poplesia usually remained in the bottom waters in the upstream part of the estuary, but it displayed strong tidally-oriented vertical migration in the middle reaches of the estuary.Taking into account the hydrographic characteristics of the Jiulong Estuary,it was hypothesized that the planktonic copepods in this estuary had more or less adopted the mechanism of vertically migrating to the surface waters during flood tide in order to make use of the inflowing tide, and then sinking to the bottom during ebb tide to avoid being carried out of the estuary by net outflow.SHANG Xu WANG Guizhong LI Shaojing GUO Donghui 2007Acta Oceanologica Sinica2007,26,4:1
