Monitoring system has become one of the most important means for perimeter intrusion prevention. But most of existing monitoring systems are passive surveillance. In this paper, we propose a method to implement active perimeter intrusion detection by identifying human targets in video images captured by monitoring system. In order to enhance the robustness of detecting postures of human targets, this paper introduces Fourier Descriptor (FD) and Histogram of Oriented Gradients (HOG) to realize an effective detection of human bodies with multiple postures captured by fixed cameras. The experiment results confirm that the proposed algorithm has higher recognition rate for detecting human targets with walking, climbing, and jumping postures, and sufficiently meets the requirements of perimeter intrusion detection.

Insect odorant binding proteins (OBPs) paly an important role in the recognition and transmission signals. One odorant binding protein gene, TcasOBP7G, was significantly up-regulated after exposure to eucalyptol. Never theless, the causal role of TcasOBP7G in Tribolium castaneum is still unclear. Here, TcasOBP7G was cloned and characterized from T. castaneum, aligning with the typical characteristic of Minus-C OBPs. The analysis of gene expression profile showed that TcasOBP7G is highly expressed at late larval and adult stage, with particularly high expression levels in ovary and testis of adults, suggesting that TcasOBP7G might be associated with reproduction of T. castaneum. Furthermore, RNAi of TcasOBP7G led to a decrease in spawning, while the development of gonads was normal, suggesting that TcasOBP7G may medicate the reproduction of T. castaneum. Additionally, the mRNA level of TcasOBP7G was significantly increased after exposure to eucalyptol, and knockdown of TcasOBP7G resulted in an increased susceptibility of T. castaneum to eucalyptol, indicating that TcasOBP7G is associated with the tolerance of T. castaneum to eucalyptol. Altogether, these results indicate that TcasOBP7G is required for both reproduction and defense against phytochemical in T. castaneum. This study will provide a theoretical basis for the development of novel control strategies based on the olfaction of insects.

Zhang, Rui,Kang, Kyoung Ah,Piao, Mei Jing,Lee, Kyoung Hwa,Jang, Hye Suk,Park, Min Jeong,Kim, Bum Joon,Kim, Jin Sook,Kim, Young Sup,Ryu, Shi Yong,Hyun, Jin Won Taylor Francis 2007 Journal of toxicology and environmental health. Pa Vol.70 No.13

<P> The antioxidant properties of rhapontigenin and rhaponticin isolated from Rheum undulatum were investigated. Rhapontigenin was found to scavenge intracellular reactive oxygen species (ROS), the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, and hydrogen peroxide (H2O2). The radical scavenging effect of rhapontigenin was more effective than rhaponticin. Rhapontigenin protected against H2O2-induced membrane lipid peroxidation and cellular DNA damage, which are the main targets of oxidative stress-induced cellular damage. The radical scavenging activity of rhapontigenin protected Chinese hamster lung fibroblast (V79-4) cells exposed to H2O2 by inhibiting apoptosis. Rhapontigenin inhibited cell damage induced by serum starvation and was also found to increase the activity of catalase and its protein expression. Further, rhapontigenin increased phosphorylation of extracellular signal-regulated kinase (ERK) and inhibited the activity of activator protein 1 (AP-1), a redox-sensitive transcription factor. In summary, these results suggest that rhapontigenin protects V79-4 cells against oxidative damage by enhancing the cellular antioxidant activity and modulating cellular signal pathways.</P>

Zhang, Zhen-Yong,Jin, Xue-Ying,Wu, Rong,Wu, Li-Na,Xing, Rui,Yang, Shu-Juan,Xie, Yao Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.3

Aim: We conducted a meta-analysis to analyze the influence of GSTM1 and GSTT1 gene polymorphisms on cervical cancer risk, and explore gene-environment interactions. Methods: Identification of relevant studies was carried out through a search of Medline and the EMbase up to Oct. 2011. All case-control studies that investigated the association between GSTM1 and GSTT1 gene polymorphisms and risk of cervical cancer were included. The pooled odds ratio (OR) was used for analyses of results and the corresponding 95% confidence intervals (CI) were estimated. Results: A total of 21 case-control studies were included in the meta-analysis of GSTM1 (2,378 cases and 2,639 controls) and GSTT1 (1,229 cases and 1,223 controls) genotypes. The overall results showed that the GSTM1 null was related to an increased risk of cervical cancer (OR=1.50, 95% CI=1.21-1.85). Subgroup analysis were performed based on smoking and ethnicity. Our results showed that smokers with null GSTM1 genotype had a moderate increased risk of cervical cancer (OR=1.85, 95% CI=1.07-3.20). For the ethnicity stratification, moderate significantly increased risk of null GSTM1 genotype was found in Chinese (OR=2.12, 95% CI=1.43-3.15) and Indian populations (OR=2.07, 95% CI=1.49-2.88), but no increased risk was noted in others. Conclusion: This meta-analysis provided strong evidence that the GSTM1 genotype is associated with the development of cervical cancer, especially in smokers, and Chinese and Indian populations. However, no association was found for GSTT1 null genotype carriers.

Zhang, Rui-Yang,Yoon, Ilkyu,Zhu, Wei-Yun,Mao, Sheng-Yong Asian Australasian Association of Animal Productio 2013 Animal Bioscience Vol.26 No.8

To evaluate lactation performance and changes in plasma and fecal lipopolysaccharide (LPS) concentrations in response to the supplementation of Saccharomyces cerevisiae fermentation product (SC), two dairy farms were selected. On each farm, 32 cows in early to mid lactation (21 to 140 DIM) were blocked by parity and days in milk (DIM), and randomly assigned to one of the two treatments within block (Control or 56 g SC/cow/d). Effect of SC on lactation performance (daily) and changes in blood and fecal LPS level were examined on d 0 and 28 of supplementation. The results showed that SC supplementation increased lactation performance of dairy cows on both farms. On Farm 1, milk production, 3.5% fat corrected milk (FCM), and yield of milk fat and protein were greater (p<0.01) for cows supplemented with SC. Supplementation of SC increased percentage milk fat (p = 0.029) from 81 to 110 DIM. There was no significant effect (p>0.05) of SC supplementation on percentage of milk protein, dry matter intake and feed efficiency. On Farm 2, cows supplemented with SC had a greater (p<0.05) milk yield, percentage of milk fat and milk protein, yield of milk fat and protein, 3.5% FCM and feed efficiency. Supplemental SC had no effect on LPS concentrations in feces (p>0.05) while it trended to reduce (p = 0.07 or 0.207) the concentration in plasma. The results indicate that supplemental SC can increase lactation performance of dairy cattle and has potential for reducing plasma LPS concentration.

Design and testing of CFRP sleeve for a high-speed permanent magnet synchronous motor with surface-mounted rotor

Yong Zhou,Lei Tian,Sheng-Hua Gao,Jing-Wei Zhang,Lin-Ke Yang,Rui-Guang Xie 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.1

A high-speed (HS) permanent magnet (PM) synchronous motor (HSPMSM) with a carbon fiber-reinforced plastic (CFRP) protective sleeve in the surface-mounted rotor was explored in this study. In view of retaining the PMs at HS operations, the high-strength CFRP sleeve was designed on the basis of a process that could be summarized as follows. First, a multi-physics analysis of the rotor was conducted. The requirements to the CFRP sleeve were obtained from electromagnetic analysis, loss analysis, heat flow coupling computational fluid dynamics analysis, structural analysis, and rotor dynamics analysis. Second, the CFRP sleeve was designed by theoretical analysis. From the results, the thickness values of the carbon fibers in the circumferential and helical directions were chosen to be 4 and 1 mm, respectively, while the helical angle of carbon fibers was chosen to be 70°. Then, a plateshaped CFRP product and a cylindrical CFRP product were fabricated to verify the strength and stiffness of the CFRP sleeve. The performance test results show that the hoop strength and elastic modulus and the axial strength and elastic modulus of the plate-shaped CFRP products at 20 °C are 1963 MPa @ 156 GPa and 550 MPa @ 36 GPa, respectively. The hoop strain and axial strain of the cylindrical CFRP product under 35 MPa are about 3000 and 1900 με, which meet the design requirements of the HSPMSM.

( Rui Zhang ),( Yong Ji Piao ),( Lin Sen Cao ),( Tae Dong Cho ) 한국환경과학회 2014 한국환경과학회지 Vol.23 No.6

Based on the survey of the parks in Tai``an by questionnaire survey, on-the-spot investigation and in-depth interview, the paper analyzes the tendencies of visitors in modern landscape lighting design forms and methods from two terms: primary attributes and the preferences of artistic lighting design. To increase the safety of the parks is a pressing need for visitors. Visitors have a pressing need for increasing the safety of the parks`` lighting and artistic quality. Most visitors think the parks`` lighting has blind spots and the brightness is not enough. Visitors’ night activities in the park will be insecure. As to artistry aspects, people prefer strong artistic style of lamps and lanterns to the common, such as ethnic style and animal image; Tourists prefer to use white light and yellow light to illuminate trees, because these colors make people feel more warm and amiable. This research provides basic data for lighting design of parks.

Tenascin-C Produced by Oxidized LDL-Stimulated Macrophages Increases Foam Cell Formation through Toll-like Receptor-4

Rui Liu,Lihua Zhang,Yong He,Bo Li,Jun Liu,Yingang Ren,Wei Han,Xing Wang 한국분자세포생물학회 2012 Molecules and cells Vol.34 No.1

Atherosclerosis is a chronic inflammatory disease in which both innate and adaptive immunity are involved. Although there have been major advances in the involve-ment of toll-like receptor 4 (TLR4) and CD36 in the initiation and development of this disease, detailed mechanisms remain unknown. Here, we show that tenascin-C (TN-C) can stimulate foam cell formation and this can be inhibited by a TLR4-blocking antibody or CD36 gene silencing. Our results identify TN-C-TLR4 activation as a common molecular mechanism in oxLDL-stimulated foam cell formation and atherosclerosis. In addition, CD36 is the major scavenger receptor responsible for the TN-C-mediated foam cell formation. Taken together, we have identified that TN-C produced by oxLDL-stimulated macrophages increases foam cell formation through TLR4 and scavenger receptor CD36.

Self-curling 3D oriented scaffolds from fish scales for skeletal muscle regeneration

Shi Yong,Zhang Xiaoxuan,Liu Rui,Shao Xiaoyan,Zhao Yuanjin,Gu Zhuxiao,Jiang Qing 한국생체재료학회 2023 생체재료학회지 Vol.27 No.00

Volumetric muscle loss (VML) due to various reasons may cause motor dysfunction and tissue engineering has been proposed for muscle regeneration. However, developing three-dimensional (3D) tissue-engineered scaffolds that can mimic oriented cell growth of muscle tissues are challenging for regeneration medicine. Herein, we propose a novel self-curling 3D oriented scaffold (SCOS) composed of fish derived gelatin methacrylate (GelMA) and fish scales for repairing skeletal muscles.Fish scales of tilapia were decellularized and decalcified. Then, SCOSs were constructed by ultraviolet-coating methylated fish gelatin on the back of fish scales. C2C12 myoblasts were cultured on SCOSs, and after induction of myogenic differentiation, SCOS/C2C12 transplants were prepared for in vivo experiments.Decellularized and decalcified fish scales (DDFSs) became soft and retained the original oriented microgroove surface structure that could induce oriented cell growth. SCOSs could self-curl into 3D structures when immersing in culture medium due to different swelling properties of fish GelMA and DDFSs. Cell experiments demonstrated that SCOSs enhanced the oriented growth and myogenic differentiation of C2C12 myoblasts. By integrating SCOSs and myogenic differentiated C2C12 myoblasts, the resultant SCOS/C2C12 transplants promoted de novo muscle regeneration and functional restoration of muscle activity in the mouse model of VML.Our results suggest that SCOSs loaded with myogenic differentiated C2C12 myoblasts can promote muscle regeneration in mice with skeletal muscle injuries, indicating application prospects of such scaffolds in muscle tissue engineering and other related fields.
