| 2 | Replacement of Dietary Fish Oil with Vegetable Oils Improves the Growth and Flesh Quality of Large Yellow Croaker(Larmichthys crocea)显示文摘We investigated the effect of the replacement of dietary fish oil with vegetable oils on the growth and flesh quality of large yellow croaker(Larmichthys crocea). The basal diet(FO) was formulated to contain 66.5% fish meal and 6.4% menhaden fish oil; whereas the other 3 experimental diets were formulated by replacing the fish oil with 50% soybean oil(SO50), 100% soybean oil(SO100) and 100% palm oil(PO100), respectively. The 4 diets were randomly assigned to 4 floating sea cages(3.0 m × 3.0 m × 3.0 m), and each was stocked with 250 fish individuals with an initial average weight of 245.29 g ± 7.45 g. The fish were fed to apparent satiation twice a day at 5:00 and 17:00, respectively, for 12 weeks. Experimental analysis showed that the specific growth rate of fish fed SO50 or PO100 were significantly higher than that of fish fed FO or SO100(P<0.05), and crude lipid contents of ventral muscle and viscera were significantly lower in fish fed FO than in those fed the other 3 diets(P<0.05). No significant differences in condition factor, viscerosomatic index, hepatosomatic index, gutted yield and colorimetric values of fish among the dietary treatments were observed(P>0.05). Compared to FO diet, SO50, SO100 and PO100 diets led to substantial decreases in the liquid loss and water loss from fresh fillets(1 d, 4℃)(P<0.05). Similarly, thiobarbituric acid reactive substance(TBARS) values of fillets under different storage conditions(1 d, 4℃; 7 d, 4℃; 4 weeks,-20℃; 8 weeks,-20℃) decreased significantly after partial or complete replacement of fish oil with vegetable oils. These findings indicated that the growth performance and selected flesh quality properties(liquid holding capacity and TBARS value) of large yellow croaker were substantially improved by replacing dietary fish oil with vegetable oils. | DUAN Qingyuan MAI Kangsen SHENTU Jikang AI Qinghui ZHONG Huiying JIANG Yujian ZHANG Lu ZHANG Chunxiao GUO Sitong | 2014 | Journal of Ocean University of China2014，13，3： | 11 |
| 3 | Effects of Dietary Corn Gluten Meal on Growth Performance and Protein Metabolism in Relation to IGF-I and TOR Gene Expression of Juvenile Cobia (Rachycentron canadum)显示文摘A growth experiment was conducted on cobia(Rachycentron canadum,initial weight 108.2 g ± 3.0 g) to investigate the effects of dietary corn gluten meal(CGM) levels on the fish growth,whole body composition and protein metabolism in relation to specific gene expression.Five isonitrogenous(crude protein 45%) and isoenergetic(gross energy 20 kJ g 1) practical diets were formulated by replacing 0%(the control),17.5%,35.0%,52.5%,and 70.0% of fish meal(FM) protein with CGM protein.No significant differences were observed in the survival,feed intake(FI),specific growth rate(SGR),feed efficiency(FE) and protein productive value(PPV) among fish fed diets with 0%,17.5%,35.0%,and 52.5% of CGM protein.However,these indices were significantly lower in fish fed the diet with 70.0% of CGM protein than those in fish fed the control diet(P < 0.05).The whole-body crude protein and lipid contents were significantly lower while the whole-body moisture content was significantly higher in fish fed the diet with 70.0% of CGM protein compared with the control group(P < 0.05).When 70.0% of FM protein was replaced by CGM,plasma total protein and cholesterol contents were significantly lower than those in the control group(P < 0.05).Fish fed the diet with 70.0% of CGM protein had significantly lower hepatic insulin-like growth factor I(IGF-I) expression levels than those in the control group(P < 0.05).However,no significant differences were observed in hepatic target of rapamycin(TOR),dorsal muscle IGF-I and TOR expression levels among dietary treatments.Results of the present study indicated that 52.5% of FM protein could be replaced by CGM in the diets without significant influences on the growth,feed utilization and protein metabolism of juvenile cobia.The present results might be useful for developing cost effective and sustainable cobia dietary formulations. | LUO Yiwen AI Qinghui MAI Kangsen ZHANG Wenbing XU Wei ZHANG Yanjiao LIUFU Zhiguo | 2013 | Journal of Ocean University of China2013，12，3： | 10 |
| 4 | Effects of Dietary Stachyose on Growth Performance, Digestive Enzyme Activities and Intestinal Morphology of Juvenile Turbot(Scophthalmus maximus L)显示文摘A 12-week feeding trial was conducted to evaluate the effects of dietary stachyose on the growth performance, digestive enzymes activities and intestinal structures of juvenile turbot(Scophthalmus maximus L). Five isonitrogenous(49.58% crude protein) and isolipidic(10.50% crude lipid) diets were formulated to contain 0(Control), 0.625%(S-0.625), 1.25%(S-1.25), 2.5%(S-2.5) and 5%(S-5) stachyose, respectively. With the increase of stachyose level, the growth performance and feed utilization of turbot, such as the specific growth rate, final mean body weight, weight gain rate and feed efficiency, increased significantly(P < 0.05) and then stabilized. The feed intake of fish fed S-5 was significantly higher(P < 0.05) than that of fish in other groups. The activities of trypsin, intestinal caseinolytic, stomach and intestinal amylase were significantly influenced by stachyose(P < 0.05). The highest values of trypsin and intestinal caseinolytic activities were observed in group S-1.25, while the highest activity of stomach amylase and the lowest activity of intestine amylase were observed in group S-5. No lesion or damage was found on the distal intestine structures of fish from all treatments, while the height of simple folds in the distal intestine was significantly increased(P< 0.05) when 1.25% or 2.5% stachyose was added in the diets. These results indicated that moderate level of stachyose(1.25%) improves the growth performance, feed utilization, digestive enzyme activities and the distal intestine structures of juvenile turbot. | HU Haibin ZHANG Yanjiao MAI Kangsen AI Qinghui XU Wei ZHANG Wenbing LI Yanxian LIU Jintao | 2015 | Journal of Ocean University of China2015，14，5： | 10 |
| 5 | Effects of Dietary Soy Isoflavones on Feed Intake,Growth Performance and Digestibility in Juvenile Japanese Flounder(Paralichthys olivaceus)显示文摘An 8-week feeding trial was conducted to investigate the effects of dietary soy isoflavones on feeding intake,growth performance,and digestion of juvenile Japanese flounder(Paralichthys olivaceus).Four isonitrogenous(49% crude protein) and isoenergetic(20.1 MJ kg-1) diets were formulated to contain four graded levels of soy isoflavones,namely,0,1,4 and 8 g soy isoflavones in 1 kg of diet.Each diet was randomly fed to triplicate tanks of fish(Initial average weight:2.58 g ± 0.01 g),and each tank was stocked with 35 fish.No significant difference was observed among diets with levels of 0,1 and 4 g kg-1 soy isoflavones in feed intake,weight gain,feed efficiency ratio(FER),proximate composition of fish whole body and apparent digestibility coefficients(ADC) of nutrients and energy(P>0.05).However,high dietary soy isoflavones level(8 g kg-1) significantly depressed weight gain,FER,whole-body crude lipid content of fish and ADC of nutrients(P<0.05).These results indicate that high level of dietary soy isoflavones(above 4 g kg-1) significantly depresses growth responses and FER of Japanese flounder.However,as the content of soy isoflavones in soybean meal is around 1 to 3 g kg-1,the adverse effects might be neglected when soybean products are used as a fish feed ingredient. | MAI Kangsen ZHANG Yanjiao CHEN Wei XU Wei AI Qinghui ZHANG Wenbing | 2012 | Journal of Ocean University of China2012，11，4： | 9 |
| 6 | Effects of Brown Fish Meal Replacement with Fermented Soybean Meal on Growth Performance, Feed Efficiency and Enzyme Activities of Chinese Soft-shelled Turtle, Pelodiscus sinensis显示文摘A 120-day feeding experiment was conducted to investigate the effects of partial replacement of brown fish meal (BFM) by fermented soybean meal (FSBM) in diets of Chinese soft-shelled turtle (Pelodiscus sinensis). The turtles (initial mean body weight, (115.52 ± 1.05) g) were fed with three experimental diets, in which 0%, 4.72% and 9.44% BFM protein was replaced by 0%, 3% and 6% FSBM, respectively. Results showed that the feeding rate (FR), specific growth rate (SGR) and feed efficiency ratio (FER) of turtles fed with the diet containing 3% FSBM were not significantly different from the control group (0% FSBM) (P > 0.05). However, FR, SGR and FER of turtles fed with the diet containing 6% FSBM were significantly lower than those of the control group (P < 0.05). No significant differences were observed in the activities of serum glutamic-oxalacetic transaminase and glutamicpyruvic transaminase among dietary treatments (P > 0.05). However, the uric acid concentration in turtles fed with the diet containing 3% or 6% FSBM was significantly lower than that in the control group (P < 0.05). There were no significant differences in the activities of lysozyme, alkaline phosphatase and total superoxide dismutase among dietary treatments (P > 0.05). The results suggested that FSBM could replace 4.72% BFM protein in turtle diets without exerting adverse effects on turtle growth, feed utilization and measured immune parameters. | ZOU Yurong AI Qinghui MAI Kangsen ZHANG Wenbing ZHANG Yanjiao XU Wei | 2012 | Journal of Ocean University of China2012，11，2： | 7 |
| 7 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (http://gffzzc750bc0108fa4044s6pq5ncn0fcvw6fx5.ffgz.tsg.suse.edu.cn/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018，11，11： | 7 |
| 8 | Low-latency deep-reinforcement learning algorithm for ultrafast fiber lasers显示文摘The application of machine learning to the field of ultrafast photonics is becoming more and more extensive.In this paper,for the automatic mode-locked operation in a saturable absorber-based ultrafast fiber laser(UFL),a deep-reinforcement learning algorithm with low latency is proposed and implemented.The algorithm contains two actor neural networks providing strategies to modify the intracavity lasing polarization state and two critic neural networks evaluating the effect of the actor networks.With this algorithm,a stable fundamental modelocked(FML)state of the UFL is demonstrated.To guarantee its effectiveness and robustness,two experiments are put forward.As for effectiveness,one experiment verifies the performance of the trained network model by applying it to recover the mode-locked state with environmental vibrations,which mimics the condition that the UFL loses the mode-locked state quickly.As for robustness,the other experiment,at first,builds a database with UFL at different temperatures.It then trains the model and tests its performance.The results show that the average mode-locked recovery time of the trained network model is 1.948 s.As far as we know,it is 62.8%of the fastest average mode-locked recovery time in the existing work.At different temperatures,the trained network model can also recover the mode-locked state of the UFL in a short time.Remote algorithm training and automatic mode-locked control are proved in this work,laying the foundation for long-distance maintenance and centralized control of UFLs. | QIUQUAN YAN QINGHUI DENG JUN ZHANG YING ZHU KE YIN TENG LI DAN WU TIAN JIANG | 2021 | Photonics Research2021，9，8： | 7 |
| 9 | Protective Effect of Holothurian Intestine Against Indomethacin Induced Gastric Mucosal Damage in Rats显示文摘Our study aimed to investigate the protective effects of Holothurian intestines(HI) on NSAIDs-induced gastric mucosal damage and the possible mechanism. At first, 60 male Wistar rats were induced of gastric lesions with indomethacin(IDM, 30 mg kg^(-1)). The rats were pretreated for 15 consecutive days with saline, sucralfate, or HI(0.4g kg^(-1) d-1, 0.8 g kg^(-1) d^(-1) and 1.6 g kg^(-1) d^(-1)) prior to IDM treatment, followed by evaluations of macroscopic damage and microscopic features; and investigation of the levels of inflammatory cytokines, oxidative stress parameters, gastric mucosal prostaglandin E2(PGE2) and total hexosamine in tissues. The expression of COX-1 and COX-2 m RNA in the gastric tissue were determined by quantitative polymerase chain reaction(q PCR). Pathological gastric ulcer indexes, levels of pro-inflammatory cytokines(IL-1β, IL-17, TNF-α) and lipid peroxidation were significantly decreased in HI-treated groups, whereas the levels of protective factors(TGF-β, GSH, SOD activity and PGE2) were significantly elevated especially in the group with HI 1.61 g kg^(-1) d^(-1)(P < 0.05). Furthermore, the expression of COX-2 mRNA decreased significantly in HI groups(P < 0.05). The study investigates that holothurian intestines may act as a kind of marine medicine which have protective effect on IDM-induced gastric ulcer, which could be a dietary preventive agent for the prevention of gastric damage. | LI Xiaoyu QIAO Xuejing ZHANG Cuiping GAO Hua NIU Qinghui WU Tong ZHANG Qi TIAN Zibin | 2017 | Journal of Ocean University of China2017，16，3： | 4 |
| 10 | Proline with or without Hydroxyproline Influences Collagen Concentration and Regulates Prolyl 4-Hydroxylase α(I) Gene Expression in Juvenile Turbot(Scophthalmus maximus L.)显示文摘This study was conducted to investigate the effect of dietary proline(Pro), and Pro and hydroxyproline(Hyp) in combination on the growth performance, total Hyp and collagen concentrations of tissues, and prolyl 4-hydroxylase α(I)(P4H α(I)) gene expression in juvenile turbot feeding high plant protein diets. A diet containing 50% crude protein and 12% crude lipid was formulated as the basal and control, on which other two protein and lipid contents identical experimental diets were formulated by supplementing the basal with either 0.75% Pro(Pro-0.75) or 0.75% Pro and 0.75% Hyp(Pro+Hyp). Four groups of fish in indoor seawater recirculating systems, 35 individuals each, were fed twice a day to apparent satiation for 10 weeks. The results showed that dietary Pro and Hyp supplementation had no significant effect on growth performance and feed utilization of juvenile turbot(P > 0.05). Total Hyp and collagen concentrations in muscle were significantly increased when dietary Pro and Hyp increased(P < 0.05), and fish fed diet Pro+Hyp showed significantly higher free Hyp content in plasma than those fed other diets(P < 0.05). The expression of P4 H α(I) gene in liver and muscle was significantly up regulated in fish fed diet Pro-0.75 in comparison with control(P < 0.05); however the gene was significantly down regulated in fish fed diet Pro+Hyp in muscle in comparison with fish fed diet Pro-0.75(P < 0.05). It can be concluded that supplement of crystal L-Pro and L-Hyp to high plant protein diets did not show positive effects on growth performance of juvenile turbot, but enhanced total collagen concentrations in muscle. | ZHANG Kaikai MAI Kangsen XU Wei ZHOU Huihui LIUFU Zhiguo ZHANG Yanjiao PENG Mo AI Qinghui | 2015 | Journal of Ocean University of China2015，14，3： | 4 |
| 11 | Effect of Dietary Olaquindox on the Growth of Large Yellow Croaker(Pseudosciaena crocea R.) and the Distribution of Its Residues in Fish Tissues显示文摘Olaquindox(OLA), one of quinoxaline-N, N-dioxides, has been put under ban. However it was used as a medicinal feed additive early; it promotes the growth of livestock and prevents them from dysentery and bacterial enteritis. In this study, we evaluated the effect of dietary OLA on the growth of large yellow croaker(Pseudosciaena crocea R.) and the histological distribution of OLA and its metabolite 3-methyl-quinoxaline-2-carboxylic acid(MQCA) in fish tissues. Four diets containing 0(control), 42.5, 89.5 and 277.2 mg kg-1 OLA, respectively, were formulated and tested, 3 cages(1.0 m × 1.0 m × 1.5 m) each diet and 100 juveniles(9.75 ± 0.35 g) each cage. The fish were fed to satiation twice a day at 05:00 am and 17:00 pm for 8 weeks. The survival rate of fish fed the diet containing 42.5 and 89.5 mg kg-1 OLA was significantly higher than that of fish fed the diet containing 0 and 277.2 mg kg-1 OLA(P < 0.05), while the weight gain rate of fish fed the diet containing 42.5 and 89.5 mg kg-1 OLA was significantly higher than that of fish fed the diet without OLA(control)(P<0.05), but similar to that of fish fed the diet with 277.2 mg kg-1 OLA. Fish fed the diet with 277.2 mg kg-1 OLA had the highest content of OLA and MQCA in liver(3.44 and 0.39 mg kg-1, respectively), skin(0.46 and 0.09 mg kg-1, respectively) and muscle(0.24 and 0.06 mg kg-1, respectively). In average, fish fed the diet containing OLA had the highest content of OLA and MQCA in liver which was followed by skin and muscle(P < 0.05), whereas OLA and MQCA were not detectable in control. Our findings demonstrated that OLA and MQCA accumulated in large yellow croaker when it was fed with the diet containing OLA, thus imposing a potential safety risk to human health. | LI Huitao WANG Weifang MAI Kangsen AI Qinghui ZHANG Chunxiao ZHANG Lu | 2014 | Journal of Ocean University of China2014，13，5： | 3 |

| 13 | Method to Detect Granary Storage Weight Based on the Janssen Model显示文摘This study proposes a new model of granary storage weight detection based on the Janssen model to satisfy the strategic requirements of granary storage quantity detection in China. The model theoretically elucidates the relationship between granary storage weight and bottom/side pressure. A new layout of pressure sensors along the inner and outer rings is also proposed to obtain the pressure value. The experimental results indicate that the detection error of the proposed model is significantly lower than 1% with respect to the low-cost detection system, and this effectively satisfies the actual requirement for real-time monitoring of granary storage quantity. | ZHANG Dexian ZHANG Miao ZHANG Qinghui ZHANG Yuan LYU Lei | 2018 | Grain & Oil Science and Technology2018，1，1： | 2 |
| 14 | Protective Effects of Oyster Extract Against Hepatic Tissue Injury in Alcoholic Liver Diseases显示文摘Oyster extract is an effective bioactivity component. It has abundant nutritional value and antiviral, antitumor and immune defense functions. The role of oyster extract in treating liver injury has been paid more attention. We use Wistar rats to make alcoholic liver disease model through injecting alcohol into rats' stomachs. These rats were randomly divided into five groups: model group, control group, low-dose, middle-dose and high-dose experimental group with a dose of 0.12 g kg-1, 0.40 g kg-1, and 1.20 g kg-1 alcoholic. After nine weeks, serum biomarkers(ALT, AST, TG and TCHO), malondialdehyde(MDA), glutathione(GSH), C3a, C5a, IL-17, TNF-ɑ, anti-MAA-HAS IgG, CD3+, CD4+, CD8+, NK cell activation and zinc content were assessed. The results showed that the serum biomarkers(ALT, AST, TG and TCHO), MDA content, anti-MAA-HSA IgG, serum C3a, C5a IL-17 and TNF-ɑ levels of oyster extract treatment groups were significantly decreased in comparison with model group. On the contrary, GSH showed adverse trend. Serum CD3+, CD4+ and NK cell activation were significantly increased in middle-dose group and high-dose group compared with model group, and there was decrease of CD8+ activity in high-dose group. Plasma Zn level was decreased in model group compared with that in control group. Meanwhile, Mean plasma Zn levels increased dramatically following the dose increase of a given oyster extract. | ZHANG Cuiping LI Xiaoyu JING Xue ZHANG Bo ZHANG Qi NIU Qinghui WANG Jianjun TIAN Zibin | 2014 | Journal of Ocean University of China2014，13，2： | 2 |
| 15 | Image Inpainting Based on Improved Deep Convolutional Auto-encoder Network显示文摘This paper proposes an effective image inpainting method using an improved deep convolutional auto-encoder network.By analogy with exiting methods of image inpainting based on auto-decoders,inpainting methods using the deep convolutional auto-encoder networks are significantly more effective in capturing high-level features than classical methods based on exemplar.However,the inpainted regions would appear blurry and global inconsistency.To alleviate the fuzzy problem,we improved the network model by adding skip connections between mirrored layers in encoder and decoder stacks,so that the generative process of the inpainting area can directly use the low-level features information of the processing image.For making the inpainted result look both more plausible and consistent with its surrounding contexts,the model is trained with a combination of standard pixel-wise reconstruction loss and two adversarial losses which ensures pixel-accurate and local-global contents consistency.With extensive experimental on the ImageNet and Paris Streetview datasets,we demonstrate qualitatively and quantitatively that our approach performs better than state of the art. | QIANG Zhenping HE Libo DAI Fei ZHANG Qinghui LI Junqiu | 2020 | Chinese Journal of Electronics2020，29，6： | 2 |
| 16 | SNR periodical variation of Chang'E-3 spacecraft orbiting the Moon显示文摘Chang'E-3 spacecraft was orbiting the Moon from December 6–14, 2013, and very long baseline interferometry(VLBI) observations were performed to improve the accuracy of its orbit determination. In the process of recording VLBI raw data, 2 bits quantization was implemented.Interesting phenomenon was that signal-to-noise ratio(SNR) of each VLBI station experienced periodical change and had large variation on amplitude while in the Moon's orbit, whereas SNR kept in a stable level after Chang'E-3 landed on the Moon. Influence of varying elevation angle on SNR was analyzed and compensation of 2 bits quantization harmonics to SNR calculation was investigated. Most importantly, telescope system noise temperature increase caused by the Moon was computed along the time of Chang'E-3 orbiting the Moon, and well matched SNR changing trend in terms of correlation coefficients. | he qingbao liu qinghui li peijia kawaguchi noriyuki wu yajun zheng xin zhang juan xu zhijun | 2016 | Chinese Journal of Aeronautics2016，29，2： | 2 |
| 17 | Study of magnetic and magneto-optical properties of heavily doped bismuth substitute yttrium iron garnet (Bi∶YIG) film显示文摘The magnetic and magneto-optical properties of heavily doped Bi∶YIG film were studied. The film was deposited by radio frequency magnetron sputtering method and crystallized by rapid recurrent thermal annealing (RRTA). The results show that the RRTA treated film has good properties both in microwave and optical wave band. The saturation magnetization of the film on different substrates varies from 135.7 to 138.6 kA·m-1. The coercive field of the film on GGG substrate is about 0.32 kA·m-1, while about 0.8-1.43 kA·m-1 on YAG substrate and 1.75 kA·m-1 on Al2O3 substrate. The Faraday angle is about 3-5 (°)·μm-1 when optical wavelength ranges at 450-600 nm. The transmission spectra of the Bi∶YIG films on three substrates has similar change as annealing temperature below 800 ℃. Specially, when annealing temperature is above 800 ℃ a step is observed between 550 and 650 nm wavelength for the film deposited on Al2O3 substrate.Three results are very useful in magneto-optical recording application and integrated microwave devices. | YANG Qinghui ZHANG Huaiwu LIU Yingli | 2006 | Rare Metals2006，25，z1： | 2 |
| 18 | TAT Improves in vitro Transportation of Fortilin Through Midgut and into Hemocytes of White Shrimp Litopenaeus vannamei显示文摘Fortilin is a multifunctional protein implicated in many important cellular processes. Since injection of Pm-fortilin reduces shrimp mortality caused by white spot syndrome virus (WSSV), there is potential application of fortilin in shrimp culture. In the present study, in order to improve trans-membrane transportation efficiency, the protein transduction domain of the transactivator of transcription (TAT) peptide was fused to fortilin. The Pichia pastoris yeast expression system, which is widely accepted in animal feeds, was used for production of recombinant fusion protein. Green fluorescence protein (GFP) was selected as a reporter because of its intrinsic visible fluorescence. The fortilin, TAT and GFP fusion protein were constructed. Their trans-membrane transportation efficiency and effects on immune response of shrimp were analyzed in vitro. Results showed that TAT peptide improved in vitro uptake of fortilin into the hemocytes and midgut of Litopenaeus vannamei. The phenoloxidase (PO) activity of hemocytes incubated with GFP-Fortilin or GFP-Fortilin-TAT was significantly increased compared with that in the control without expressed fortilin. The PO activity of hemocytes incubated with 200 μg mL-1 GFP-Fortilin-TAT was significantly higher than that in the group with the same concentration of GFP-Fortilin. Hemocytes incubated with GFP-Fortilin-TAT at all concentrations showed significantly higher nitric oxide synthase (NOS) activity than those in the control or in the GFP-Fortilin treatment. The present in vitro study indicated that TAT fusion protein improved the immune effect of fortilin. | ZHOU Yi ZHANG Wenbing MAI Kangsen XU Wei ZHANG Yanjiao AI Qinghui WANG Xiaojie | 2012 | Journal of Ocean University of China2012，11，2： | 1 |

| 20 | Enhanced performance of a fast GaAs-based terahertz modulator via surface passivation显示文摘Surface-modified semiconductors show enormous potential for opto-terahertz(THz)spatial modulation due to their enhanced modulation depth(MD)along with their inherent broad bandwidth.Taking full advantage of the surface modification,a performance-enhanced,all-optical,fast switchable THz modulator was achieved here based on the surface-passivated Ga As wafer.With a decreased surface recombination rate and prolonged carrier lifetime induced by passivation,S-passivated Ga As was demonstrated as a viable candidate to enhance THz modulation performance in MD,especially at low photodoping levels.Despite a degraded modulation rate owing to the longer carrier lifetime,this passivated Ga As modulator simultaneously realizes a fast modulation at a 69-MHz speed and as high an MD as ~94% in a spectral wideband of 0.2-1.2 THz.The results demonstrated a new strategy to alleviate the tradeoff between high MD and speed in contrast to bare surfaces or heterogeneous films/unusual geometry on semiconductors including Si,Ge,and GaAs. | YULIAN HE YUANSHENG WANG QINGHUI YANG HUAIWU ZHANG QIYE WEN | 2021 | Photonics Research2021，9，11： | 1 |
