The fleshy fruits of Camellia oleifera Abel are the immature fruits of C. oleifera, which are infected by Exobasidium vexans Massee and then turn to be intumescent and hollowed. They contain rich trace elements and vitamin C and are eaten directly as wild fruits in the Chinese countryside. Recent studies report that C. oleifera has anti-inflammatory and antioxidative effects. The current study, for the first time, evaluates the renal protective capacity of polysaccharides from the fleshy fruits of C. oleifera (CFFP) in streptozotocin-induced diabetic mice fed high-fat diets. The diabetic mice were orally administered CFFP for 3 months to evaluate the renoprotective function of CFFP. Our results indicated that 250 mg/kg CFFP significantly alleviated diabetes-induced renal injury by decreasing serum creatine, blood urea nitrogen levels, the kidney/body weight ratio, expression of fibronectin and collagen, as well as the secretion of tumor necrosis factor-α and interleukin-6. Additionally, 250 mg/kg CFFP could significantly ameliorate renal oxidative stress through increasing glutathione levels and lowering malondialdehyde contents. We confirmed that CFFP could exert antioxidative, anti-inflammatory, and antifibrosis activities. CFFP might be a potential therapeutic agent, and the fleshy fruits of C. oleifera might be a diet therapy for diabetic patients in the future.

Shunlong Li,Jialin Dong,Wei Lu,Hui Li,Wencheng Xu,Yao Jin 국제구조공학회 2017 Smart Structures and Systems, An International Jou Vol.20 No.6

Cable force monitoring is an essential and critical part of the safety evaluation of cable-supported bridges. A reasonable cable force monitoring scheme, particularly, sensor placement related to accurate safety assessment and budget costsaving becomes a major concern of bridge administrative authorities. This paper presents optimal sensor placement for cable force monitoring by selecting representative sensor positions, which consider the spatial correlativeness existing in the cable group. The limited sensors would be utilized for maximizing useful information from the monitored bridges. The maximum information coefficient (MIC), mutual information (MI) based kernel density estimation, as well as Pearson coefficients, were all employed to detect potential spatial correlation in the cable group. Compared with the Pearson coefficient and MIC, the mutual information is more suitable for identifying the association existing in cable group and thus, is selected to describe the spatial relevance in this study. Then, the bond energy algorithm, which collects clusters based on the relationship of surrounding elements, is used for the optimal placement of cable sensors. Several optimal placement strategies are discussed with different correlation thresholds for the cable group of Nanjing No.3 Yangtze River Bridge, verifying the effectiveness of the proposed method.

Study on thermal conductivity of periclase-hercynite bricks prepared from fused or sintered hercynite

Junhong Chen,Mingwei Yan, Yong Li,Zhijian Li,Jindong Su,Bin Li,Jialin Sun 한양대학교 세라믹연구소 2016 Journal of Ceramic Processing Research Vol.17 No.5

Periclase-hercynite bricks were prepared from fused or reaction-sintered hercynite. The microstructure of the obtained brickswas studied and their thermal conductivity in the simulated on-site condition was tested. The results show that the mutualdiffusion of Fe or Al from hercynite and Mg from periclase forms more pores in the material. Compared with the brickprepared from fused hercynite, the brick from reaction-sintered hercynite has smaller pore size. The thermal conductivitysimulation test of the two bricks at 1550 oC shows that the cold end temperature of the brick synthesized from the reactionsinteredhercynite is 40 oC lower than that of the brick from the fused hercynite. Thus, in consideration of reducing the shelltemperature of the cement rotary kilns, the reaction-sintered hercynite is more favorable for the production of periclasehercynitebricks.

Surprise, Image and Life: Take the “life lost” event in the Oriental life world as an example

Li Xiaoyun,Wang ping,Hou jialin 아시아사회과학학회 2021 Jornal of Asia Social Science Vol.5 No.3

In the face of images, people s feelings are not necessarily rich, but may also be confused. Whether it is rational or aesthetic. Because emotionally, what they bring is tiredness and boredom. They are narrow-minded and not full. The simple idea of life world is the perfect existence. Even the “life lost”event can also “transform” our spirit. Simple life, not simple life.

Characterization and mechanism analysis of graphite/C-doped TiO2 composite for enhanced photocatalytic performance

Jialin Jia,Dong Li,Jiafeng Wan,Xiujuan Yu 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.33 No.-

Graphite/C-doped TiO2 composite was synthesized through a modified sol–gel reaction. DRS resultsindicated that light absorbance edge of graphite/C-doped TiO2 was clearly red-shifted to visible lightregion by doping with C. SPS results displayed that separation efficiency of photoinduced charge carriersof graphite/C-doped TiO2 were greatly increased by coupling with graphite. Moreover, the photocatalyticperformance of composite was evaluated by the degradation of methyl orange (MO). Results showedthat graphite/C-doped TiO2 exhibited higher photocatalytic activity for MO than that of pristine TiO2 andP25, which was mainly attributed to the high crystallization, large surface hydroxyl groups, intensevisible light absorption and effective separation of photoinduced charge carriers.

Effects of hydrothermal parameters on the physicochemical property and photocatalytic degradation of bisphenol A of Ti-based TiO2 nanomaterials

Dong Li,Yunzhou Chen,Jialin Jia,Haiyang He,Wei Shi,Jianghua Yu,Jun Ma 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.109 No.-

Effects of hydrothermal parameters on morphology, crystal structure, light absorption, separation efficiencyof photo-generated charge carriers, and photocatalytic removal of Bisphenol A (BPA) of Ti-basedTiO2 nanomaterials were systematically investigated. Through changing hydrothermal parameters,TiO2 nanobelts, TiO2 nanosheets and TiO2 nanowires were prepared. With increasing NaOH concentration,hydrothermal temperature, and hydrothermal time, more TiO2 with (101) crystal plane grew onTi substrate, resulting in higher crystallinity. The UV-light absorption enhanced with increasing NaOHconcentration, but decreased with improving hydrothermal temperature, hydrothermal time, and HClconcentration. Variation of UV-light absorption was mainly affected by morphology, and UV-light absorptionof TiO2 nanomaterials with different morphologies was arranged in order ofnanobelts > nanosheets > nanowires. The hydrothermal growth of TiO2 nanomaterials on Ti plate conformedto Ostwald ripening mechanism. Variation trend of photo-generated current was consistent withthat of BPA degradation, they both first increased and then decreased within investigated range. The optimalNaOH concentration, hydrothermal temperature, hydrothermal time, and HCl washing concentrationwere 1 M, 170℃, 28 h, and 0.1 M, respectively. Under this condition, Ti-based TiO2 nanosheets exhibitedthe highest BPA removal efficiency (92.7%), which was due to highly ordered nanosheet structure, goodcrystallinity, appropriate UV-light absorption and high separation efficiency of electron-hole pairs.

WU JIALIN,Li Jiaying,Zhao Zhipei 한국무역전시학회 2023 무역전시연구 Vol.18 No.1

Under the background of the information age and the post-pandemic era, the construction of smart exhibition venues has become a hot topic in the exhibition industry. Smart service, as an important direction for the construction of smart venues, has aroused scholars to make relevant discussions. However, there have been some researches on specific exhibition intelligent services, little researches on exhibition hall intelligent services from the perspective of users. In addition, there are also various subjects using intelligent services in the exhibition hall. As a component of exhibitions, the subjects using intelligent services can be divided into exhibition organizers, exhibitors, visitors, service providers, etc. Due to the diverse types of intelligent services required by various subjects, the demand for intelligent services may also vary. Therefore, research on intelligent services in exhibition halls should also vary according to the needs of each subject. Exhibitors, a bridge between organizers and visitors are playing an important role in the exhibition. The income of the organizers is closely related to the satisfaction of exhibitors, which has great significance for the future development of the exhibition. In addition, from the perspective of visitors, exhibitors are the most important element of the exhibition. As one of the important exhibition subjects, exhibitors have their own foundational and particular needs for smart services. Based on the perspective of exhibitors’ needs, this research utilizes literature survey and interview methods to define exhibitors’ demand indicators for smart services in exhibition venues, and combines the Kano model to design a two-factor questionnaire to conduct research. After collecting the data, compare it to the Kano model classification comparative table to classify the demand attributes of the demand indicators, and then prioritize all demand indicators through the Better-Worse coefficient. This study found that exhibitors’ demand for smart services in exhibition venues is mostly type of charismatic demand, and the demand for smart parking lots and mobile charging stations, cloud display, and audience behavior data is of higher priority. Therefore, this research suggests that exhibition venues and exhibition organizers should use the above-mentioned higher priority demand indicators as the core to build a smart service system for exhibition venues. This research provides new ideas for the construction of smart exhibition venues and at the same time makes up for the deficiencies of academic research in this area.

Molecular Cloning and Functional Characterization of FOUR LIPS in Pomegranate, a Protein Involved in Regulating the Gravitropic Set-Point Angle of Adventitious Roots

Wang Zenghui,Li Jialin,Wang Chuanzeng,Feng Lijuan,Yin Yanlei 한국식물학회 2022 Journal of Plant Biology Vol.65 No.5

Self-rooted pomegranate seedlings are widely used in the horticultural industry to cut costs and time. However, these seedlings produce shallow roots that exhibit poor cold resistance. Thus, deeper adventitious roots generated through gravitropism are imperative for seedling survival, and understanding the molecular mechanisms of gravitropism can facilitate improved breeding techniques. We hypothesized that gravitropism in pomegranate is partially controlled by pomegranate FOUR LIPS (PgFLP), an R2R3-MYB protein that interacts with and controls the transcriptional expression of PgPIN10, which facilitates transmembrane auxin signaling. We studied subcellular localization of PgFLP, quantified auxin levels, and measured gravitropic set-point angle (GSA) to investigate the underlying mechanisms regulating PgPIN10 expression during the formation of GSA in pomegranate adventitious roots. We found that PgFLP was localized to the nucleus based on use of green florescent proteins, suggesting that this protein is a transcription factor. When using the tractable 35S::PgFLP, we observed stronger gravitational response in overexpression lines leading to a narrower GSA than in the wild-type Arabidopsis, and the expression of PgFLP and PgPIN10 in ‘Lanbaoshi’ (LBS; a deep-rooted cultivar) was higher than that in ‘Taishanhong’ (TSH; a shallow-rooted cultivar), which indicates that PgFLP may participate in regulating the GSA of adventitious roots via PgPIN10 in pomegranate. Taken together, our results indicate that the pomegranate R2R3-MYB transcription factor, PgFLP, plays a vital role in setting the GSA of adventitious roots in this crop species.

Zhiheng Hu,Yaoxian Chin,Jialin Liu,Jiaying Zhou,Gaoshang Li,Lingping Hu,Yaqin Hu 한국수산과학회 2022 Fisheries and Aquatic Sciences Vol.25 No.2

The Lophius litulon liver was used as raw material for the extraction of fish oil via various extraction methods. The extraction rate by water extraction, potassium hydroxide (KOH) hydrolysis and protease hydrolysis were compared and the results revealed the protease hydrolysis extraction had a higher extraction rate with good protein-lipid separation as observed by optical microscope. Furthermore, subsequent experiments determined neutrase to be the best hydrolytic enzyme in terms of extraction rate and cost. The extraction conditions of neutrase hydrolysis were optimized by single-factor experiment and response surface analysis, and the optimal extraction rate was 58.40 ± 0.25% with the following conditions: enzyme concentration 2,000 IU/g, extraction time 1.0 h, liquid-solid ratio 1.95:1, extraction temperature 40.5℃ and pH 6.5. The fatty acids composition in fish oil from optimized extraction condition was composed of 19.75% saturated fatty acids and 80.25% unsaturated fatty acids. The content of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were 8.06% and 1.19%, respectively, with the ratio (6.77:1) surpassed to the recommendation in current researches (5:1). The results in this study suggest protease treatment is an efficient method for high-quality fish oil extraction from Lophius litulon liver with a satisfactory ratio of DHA and EPA.

Double-Blind Compact E-cash from Bilinear Map

Jiyang Chen,Bin Lian,Yongjie Li,Jialin Cui,Ping Yu,Zhenyu Shu,Jili Tao 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.4

Compact E-cash is the first scheme which can withdraw 2l coins within (1) operations and then store them in ( ) bits. Because of its high efficiency, a lot of research has been carried out on its basis, but no previous research pay attention to the privacy of payees and in some cases, payees have the same privacy requirement as payers. We propose a double-blind compact E-cash scheme, which means that both the payer and the payee can keep anonymous while spending. In our scheme, the payer and the bank cannot determine whether the payees of two different transactions are the same one and connect the payee with transactions related to him, in this way, the privacy of the payee is protected. And our protocols disconnect the received coin from previous transaction, then, the coin can be transferred into an unspent coin which belongs to the payee. The proposed e-cash scheme is secure within y-DDHI and LRSW assumption.
