Diamondback moth (DBM), Plutella xylostella, is an important pest of crucifers worldwide. The extensive use of diamide insecticides has led to DBM resistance in the world, and this presents a serious threat to vegetable production. In the present study, transcriptomic and proteomic analyses were combined to investigate the potential flubendiamide‐resistance mechanism in DBM. The lab‐selected (Rh) and field‐collected (Rb) flubendiamide‐resistant lines of P. xylostella with resistance ratios of 1889.92‐fold and 1250.97‐fold, respectively, were used, as well as a lab‐reared flubendiamide‐susceptible line (S). Compared with the S group, the transcriptomic analysis revealed 151 upregulated and 287 downregulated gene messengers in the Rh group and 432 upregulated and 565 downregulated gene messengers in the Rb group. The most frequently enriched pathways of differentially expressed genes (DEGs) were mainly involved in metabolic pathways. Metabolism related genes, including two P450, two ABC transporters, and three trypsins, were upregulated in the Rh line. Additionally, some P450 genes, trypsin, juvenile hormone (JH), and mucin genes were also upregulated in the Rb line. In proteomic analysis comparisons with the S group, there were 78 upregulated and 90 downregulated proteins in the Rh group and 221 upregulated and 155 downregulated proteins in the Rb group. Further analyses found that three CYP and 11 CYP proteins were over‐expressed in Rh and Rb lines, respectively. Four glutathione S‐transferase (GST) and four UGTs were over‐expressed in Rb line. So, we deduced that the detoxification metabolism may be the main mechanism of flubendiamide resistance in P. xylostella.

The therapeutic effects of endothelial progenitor cells (EPCs) on ischemic stroke have been extensively studied in recent years. However, the differences in early EPCs and endothelial outgrowth cells (EOCs) are still unclear. Clarifications of their respective properties and specific functioning characteristics contribute to better applications of EPCs in ischemic diseases. In this review, we discuss cellular origin, isolation, culture, surface markers of early EPCs and EOCs and relevant applications in neurological diseases. We conclude that EOCs possess all characteristics of true endothelial progenitors and have potent advantages in EPC-based therapies for ischemic diseases. A number of preclinical and clinical applications of EPCs in neurological diseases are under study. More studies are needed to determine the specific characteristics of EPCs and the relevant mechanisms of EPCs for neurological diseases.

Yu-Ming jing,Chun-Chih Chen,Wu-Shu Ming 한국일러스트레이션학회 2019 일러스트레이션 포럼 Vol.20 No.59

This study is conducted from a design perspective with women's fashion and uses the cheongsam dress as an example within Taiwan and mainland China to investigate Chinoiserie fashion design. First, we adopt the Evaluation Grid Method of Miryoku engineering to interview subjects about their perceived cognition of Chinoiserie women's fashion to determine the purchase charm features that affect consumers the most. These findings help provide relevant references for fashion instruction personnel in the design of creative curriculum and instruction and can also add some effective information to the database of future fashion design. As our research results show, the consumer groups in mainland China and Taiwan have different perceptions of Chinoiserie fashion, while design professionals and non-design professionals have diverse preferences regarding their perceived cognition of Chinoiserie fashion. Therefore, these results indicate that people from different backgrounds have rather significant differences in terms of sensibility for Chinoiserie fashion.

Yu-lou Tian,Fang Liu,Hong-jing Sun,Pin Lv,Yu-ming Cao,Mo Yu,Yang Yue 대한치과교정학회 2015 대한치과교정학회지 Vol.45 No.5

Objective: To assess the labial and lingual alveolar bone thickness in adults with maxillary central incisors of different inclination by cone-beam computed tomography (CBCT). Methods: Ninety maxillary central incisors from 45 patients were divided into three groups based on the maxillary central incisors to palatal plane angle; lingual-inclined, normal, and labial-inclined. Reformatted CBCT images were used to measure the labial and lingual alveolar bone thickness (ABT) at intervals corresponding to every 1/10 of the root length. The sum of labial ABT and lingual ABT at the level of the root apex was used to calculate the total ABT (TABT). The number of teeth exhibiting alveolar fenestration and dehiscence in each group was also tallied. One-way analysis of variance and Tukey’s honestly significant difference test were applied for statistical analysis. Results: The labial ABT and TABT values at the root apex in the lingual-inclined group were significantly lower than in the other groups (p < 0.05). Lingual and labial ABT values were very low at the cervical level in the lingual-inclined and normal groups. There was a higher prevalence of alveolar fenestration in the lingual-inclined group. Conclusions: Lingual-inclined maxillary central incisors have less bone support at the level of the root apex and a greater frequency of alveolar bone defects than normal maxillary central incisors. The bone plate at the marginal level is also very thin.

Wu, Jing-Jing,Wang, Xin-Hua,Li, Ling,Li, Xin,Zhang, Lei,Sun, Zhen-Chang,Fu, Xiao-Rui,Ma, Wang,Chang, Yu,Zhang, Xu-Dong,Han, Li-Juan,Zhang, Ming-Zhi Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

Purpose: We developed and evaluated a regimen including fotemustine, teniposide and dexamethasone (FTD) for treating patients with central nervous system (CNS) lymphoma based on pharmacokinetic properties of individual agents and in combination. Patients and Methods: In a comparison study, 8 patients with primary CNS lymphoma (PCNSL) and 8 with secondary CNS lymphoma (SCNSL) were treated with FTD (comprising fotemustine 100 mg/m2, 1h infusion, day 1; teniposide 60 mg/m2, >0.5 h infusion, on day 2, 3, 4; dexamethasone 40 mg, 1h infusion, on day 1, 2, 3, 4 and 5; and methotrexate 12 mg, cytosine arabinoside 50 mg plus dexamethasone 5 mg intrathecally, on day 2 and 7). Cycles were repeated every 3 weeks. After response assessment, patients received whole brain radiotherapy. Results: Of the 8 PCNSL patients, 4 (50%) achieved CR and 3 (38%) PR, an overall response rate of 88%. Four patients (50%) were in continuing remission at the end of this study after a median follow-up of 30 months (range 10 to 56 months). Of the 8 SCNSL patients the overall response rate was 63% (CR+PR: 38%+25%). All responses were achievable with predictable toxicity mainly reflecting reversible myelosuppression. Conclusion: This study suggests that FTD could be an effective treatment for CNS lymphoma, and is worthy of further evaluation.

Theoretical and Experimental Investigations of the Optical Properties of Ge2Sb2Te5 for Multi-State Optical Data Storage

Jing Li,Song-You Wang,Ming Xu,Shen-Jin Wei,Song Wu,Fei Pei,Liang-Yao Chen,Yu Jia 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.4

Ge2Sb2Te5 (GST) is widely used as an excellent data recording material based on its fast and reversible amorphous-to-crystalline phase transformation that is accompanied by changes in the optical reflectivity and the electrical conductivity. It was demonstrated that GST can be transformed reversibly between the amorphous and the cubic phases, and, under certain conditions, it can be transformed between the cubic and the hexagonal phases as well. Thus, if we can take advantage of the differences in the optical and the electrical properties among the amorphous, the cubic, and the hexagonal states, we could use GST as a multi-state storage material, and its storage density would be improved remarkably. In this study, we investigate the electronic and the optical properties of crystalline GST by using both ab-initio and experimental analyses. The results show that the cubic GST is semi-conductive while the hexagonal GST may exhibit much higher conductivity. The reflectivity contrast of the two crystalline states is above 8 % in the range from 400 nm to 700 nm, indicating a potential for applications of GST in multi-state optical data storage.

Experimental Studies of Low-Field Landau Quantization in Two-Dimensional Electron Systems in GaAs/AlGaAs Heterostructures

Jing-Han Chen,Chi-Te Liang,Chun-Feng Huang,Da-Ren Hang,David A. Ritchie,J. C. Hsiao,Jyun-Ying Lin,Michelle Y. Simmons,Ming-Gu Lin,S. H. Lo,Tsai-Yu Huang 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.3

By applying a magnetic field perpendicular to GaAs/AlGaAs two-dimensional electron systems (2DESs), we study the low-field Landau quantization when the thermal damping is reduced with decreasing temperature. Magneto-oscillations following the Shubnikov-de Haas (SdH) formula are observed even when their amplitudes are so large that the deviation to such a formula is expected. Our experimental results show the importance of the positive magneto-resistance to the extension of the SdH formula under the damping induced by the disorder.

Ming Qin,Wei Chen,Zhixin Lin,Lixue Wang,Lixia Ma,Jinhong Geng,Yu Zhang,Jing Zhao,Yong-Qing Zeng 대한수의학회 2021 Journal of Veterinary Science Vol.22 No.3

Background: Interferon lambda receptor 1 (IFNLR1) is a type II cytokine receptor that clings to interleukins IL-28A, IL29B, and IL-29 referred to as type III IFNs (IFN-λs). IFN-λs act through the JAK-STAT signaling pathway to exert antiviral effects related to preventing and curing an infection. Although the immune function of IFN-λs in virus invasion has been described, the molecular mechanism of IFNLR1 in that process is unclear. Objectives: The purpose of this study was to elucidate the role of IFNLR1 in the pathogenesis and treatment of porcine reproductive and respiratory syndrome virus (PRRSV). Methods: The effects of IFNLR1 on the proliferation of porcine alveolar macrophages (PAMs) during PRRSV infection were investigated using interference and overexpression methods. Results: In this study, the expressions of the IFNLR1 gene in the liver, large intestine, small intestine, kidney, and lung tissues of Dapulian pigs were significantly higher than those in Landrace pigs. It was determined that porcine IFNLR1 overexpression suppresses PRRSV replication. The qRT-PCR results revealed that overexpression of IFNLR1 upregulated antiviral and IFN-stimulated genes. IFNLR1 overexpression inhibits the proliferation of PAMs and upregulation of p-STAT1. By contrast, knockdown of IFNLR1 expression promotes PAMs proliferation. The G0/G1 phase proportion in IFNLR1-overexpressing cells increased, and the opposite change was observed in IFNLR1-underexpressing cells. After inhibition of the JAK/STAT signaling pathway, the G2/M phase proportion in the IFNLR1-overexpressing cells showed a significant increasing trend. In conclusion, overexpression of IFNLR1 induces activation of the JAK/STAT pathway, thereby inhibiting the proliferation of PAMs infected with PRRSV. Conclusion: Expression of the IFNLR1 gene has an important regulatory role in PRRSV-infected PAMs, indicating it has potential as a molecular target in developing a new strategy for the treatment of PRRSV.

Synthesis, characterization, and visible light induced photoactivity of tourmaline-N-TiO2 composite for photooxidation of ethylene

Jing-Hua Tzeng,Chih-Huang Weng,Yu-Hao Lin,Shang-Ming Huang,Li-Ting Yen,Jin Anotai,Yao-Tung Lin 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.80 No.-

A novel visible light driven tourmaline-nitrogen-doped-TiO2 composite (S-N-TiO2) was prepared using afacile impregnation and sol gel method and its photocatalytic reaction scheme with ethylene wasproposed. X-ray diffraction analysis confirmed the presence of TiO2 in the form of anatase phase. Scanning electron microscope and energy dispersive spectrometer mapping showed that the TiO2particles were deposited and dispersed on the surface of tourmaline. Under visible light irradiation, the SN-TiO2 catalyst containing 4 wt.% tourmaline has higher photocatalytic activity for the oxidation ofethylene than pure TiO2 and N-doped-TiO2 (N-TiO2). This enhanced activity could be not only attributedto the narrowed band gap in visible light driven N-TiO2, but also improved by the spontaneous electricfield of tourmaline which was applied to restrain the recombination of the electron–hole pairs. Thephotogenerated electrons from N-TiO2 were induced by electricfield to react with ethylene, and theleaving photogenerated holes also formed the reactive species. The photocatalytic activity of S-N-TiO2 ismuch affected by synthesis conditions. This novel S-N-TiO2 photocatalyst has a promising perspective inthe gas treatment for air pollution control and horticultural product industries.

Yu, Zu-Hu,Zhang, Qiang,Wang, Ya-Dong,Chen, Jing,Jiang, Zhi-Mao,Shi, Min,Guo, Xin,Qin, Jie,Cui, Guang-Hui,Cai, Zhi-Ming,Gui, Yao-Ting,Lai, Yong-Qing Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

The aim of this study was to evaluate expression of COX-1 in renal cell carcinoma (RCC) and its prognostic value. mRNA of COX-1 was detected in 42 paired RCC and adjacent normal tissues with quantitative realtime polymerase chain reaction (qRT-PCR). Expression of COX-1 was also evaluated in 196 RCC sections and 91 adjacent normal tissues with immunohistochemistry. Statistical analysis was performed to assess COX-1 expression in RCC and its prognostic significance. The results of qRT-PCR showed mRNA levels of COX-1 in RCC tissues to be significantly higher than that in adjacent normal tissues (p < 0.001). Immunohistochemical assays also revealed COX-1 to be overexpressed in RCC tissues (p < 0.001). Statistical analysis demonstrated high expression of COX-1 was correlated with tumour size (p = 0.002), pathological stage (p = 0.003), TNM stage (p = 0.003, 0.007, 0.027, respectively), and tumour recurrence (p < 0.001). Survival analysis indicated patients with high expression of COX-1 had shorter survival time (p < 0.001), and COX-1 was an independent predictor. This is the first study to reveal overexpression of COX-1 in RRC and point to use as a prognostic marker in affected patients.
