Caineng Cao,Feng Jiang,Qifeng Jin,Ting Jin,Shuang Huang,Qiaoying Hu,Yuanyuan Chen,Yongfeng Piao,Yonghong Hua,Xinglai Feng,Xiaozhong Chen 대한암학회 2019 Cancer Research and Treatment Vol.51 No.1
Purpose The aim of this study is to evaluate the prognostic significance of paranasal sinus invasion for nasopharyngeal carcinoma (NPC) and its suitable position in the T classification. Materials and Methods The magnetic resonance imaging (MRI) scans of 695 patients with previously untreated, biopsy-proven, non-metastatic NPC that was treated with intensity-modulated radiotherapy (IMRT) were reviewed retrospectively. Results The incidence of paranasal sinus invasion was 39.4% (274 of 695 patients). Multivariate analysis showed that paranasal sinus invasion was an independent negative prognostic factor for local failure-free survival (LFFS) (p < 0.05). According to the eighth American Joint Committee on Cancer (AJCC) staging system, 275 patients were classified as T3 classification. Of these, 78 patients (28.4%) developed paranasal sinus invasion (T3b) and 197 (71.6%) didn’t (T3a). The estimated 5-year LFFS and overall survival (OS) rates for the patients with T3b and T3a classification were 88.6% versus 95.0% (p=0.047), and 84.5% versus 93.3% (p=0.183), respectively. The estimated 5-year LFFS and OS rates for the patients with T4 classification were 89.5% and 83.2%, which were similar with the outcomes of patients with T3b classification. Conclusion MRI-determined paranasal sinus invasion is an independent prognostic factor of NPC treated by IMRT. Paranasal sinus invasion is recommended to classify as T4 classification in the 8th AJCC staging system for NPC.

Raman scattering spectroscopy has been performed on high quality Co-doped ZnO epitaxial films, which were grown on Al2O3 (0001) by oxygen-plasma assisted molecular beam epitaxy. Raman measurements revealed two local vibration modes (LVMs) at 723 and 699 cm1 due to the substitution of Co2þ in wurtzite ZnO lattice. The LVM at 723 cm1 is found to be an elemental sensitive vibration mode for Co substitution. The LVM at 699 cm1 can be attributed to enrichment of Co2þ bound with oxygen vacancy, the cobalteoxygen vacancyecobalt complexes, in Zn1xCoxO films associated with ferromagnetism. The intensity of LVM at 699 cm1, as well as saturated magnetization, enhanced after the vacuum annealing and depressed after oxygen annealing.

In this study, Musca domestica pupae lectin (MPL) was screened for its immunomodulatory effect on macrophages. The phagocytosis of macrophages was improved significantly when they were treated with MPL: remarkable changes were observed in the morphology of the cells, the metabolic abilities of DNA and RNA were enhanced, and the production of hepatin was increased. Meanwhile, compared with the control group, not only the mRNA expressions of tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), and interferon-c (IFN-c) in macrophages, but also the productions of proteins,were strongly induced by MPL; these effects were inhibited by pyrrolidine dithiocarbamate. Further study suggested that MPL could increase the nuclear factor-jB (NF-jB) p65 level in the nucleus. Overall, these results indicate that the improving immunomodulatory activity induced by MPL is mainly due to the increasing productions of TNF-a, IL-6, and IFN-c and that the activation of macrophage by MPL is partly mediated via the NF-jB pathway.

By using ionic liquid 1-hexylpyridinium hexafluorophosphate ($HPPF_6$) based carbon ionic liquid electrode (CILE) as the substrate electrode, a $CoMoO_4$ nanorods and myoglobin (Mb) composite was casted on the surface of CILE with chitosan (CTS) as the film forming material to obtain the modified electrode (CTS/$CoMoO_4$-Mb/CILE). Spectroscopic results indicated that Mb retained its native structures without any conformational changes after mixed with $CoMoO_4$ nanorods and CTS. Electrochemical behaviors of Mb on the electrode were carefully investigated by cyclic voltammetry with a pair of well-defined redox peaks from the heme Fe(III)/Fe(II) redox center of Mb appeared, which indicated that direct electron transfer between Mb and CILE was realized. Electrochemical parameters such as the electron transfer number (n), charge transfer coefficient (${\alpha}$) and electron transfer rate constant ($k_s$) were estimated by cyclic voltammetry with the results as 1.09, 0.53 and 1.16 $s^{-1}$, respectively. The Mb modified electrode showed good electrocatalytic ability toward the reduction of trichloroacetic acid in the concentration range from 0.1 to 32.0 mmol $L^{-1}$ with the detection limit as 0.036 mmol $L^{-1}$ ($3{\sigma}$), and the reduction of $H_2O_2$ in the concentration range from 0.12 to 397.0 ${\mu}mol\;L^{-1}$ with the detection limit as 0.0426 ${\mu}mol\;L^{-1}$ ($3{\sigma}$).

For Internet of Things, it is more preferred to have immediate access to environment information from sensor nodes (SNs) rather than from gateway nodes (GWNs). To fulfill the goal, mutual authentication scheme between user and SNs with session key (SK) negotiation is more suitable. However, this is a challenging task due to the constrained power, computation, communication and storage resources of SNs. Though lots of authentication schemes with SK negotiation have been designed to deal with it, they are still insufficiently secure and/or efficient, and some even have serious vulnerabilities. Therefore, we design an efficient secure authentication scheme with session key negotiation (eSAS2KN) for wireless sensor networks (WSNs) utilizing fuzzy extractor technique, hash function and bitwise exclusive-or lightweight operations. In the eSAS2KN, user and SNs are mutually authenticated with anonymity, and an SK is negotiated for their direct and instant communications subsequently. To prove the security of eSAS2KN, we give detailed informal security analysis, carry out logical verification by applying BAN logic, present formal security proof by employing Real-Or-Random (ROR) model, and implement formal security verification by using AVISPA tool. Finally, computation and communication costs comparison show the eSAS2kN is more efficient and secure for practical application.

What is the Driving Force Behind the Globalisation of Karate? From a Chinese Viewpoint
Jinwen Xie,정경원,Yuanyuan Cao,Chang Liu 상명대학교 글로벌문화예술교육연구소 2023 Research in Dance and Physical Education Vol.7 No.1
Although scholars have discussed the globalisation of karate and its spread worldwide. However, the current study only discusses the spread of karate in the West through the logical reasoning of the researchers, based on scattered evidence. Thus, in this study, the authors collected 40 karate books written by Chinese people and extracted their views on it with the aim of clarifying the force responsible for the globalisation of karate from a ‘non-Western’ perspective. This study analyses their views using reflexive thematic analysis and suggests, first, the modernisation of karate was accelerated by the introduction of tournaments, and some Chinese martial artists noticed karate techniques and the rules of a contest, expecting to learn from its success. Karate became an Olympic sport in 2016, which led the Chinese to reflect on and study in depth the model of promoting the globalisation of karate. This implies that karate is recommended and actively introduced in China by the Chinese. Second, the Chinese believe that karate is a ‘one-hit kill’ (一擊必殺), implying that a single movement can kill the enemy. However, they firmly believe that the practice of karate over time not only reduces this potentially dangerous and violent nature but also promotes the health of the practitioner’s body and mind. Thus, in their perception, karate is likely to exist and function as a ‘Dao’ (道) of both the literary and martial arts.

The Role of Wheat Germ Agglutinin in the Attachment of Pseudomonas sp. WS32 to Wheat Root
Jian Zhang,Liyuan Meng,Yuanyuan Cao,Huiping Chang,Zhongyou Ma,Leni Sun,Ming Zhang,Xinyun Tang 한국미생물학회 2014 The journal of microbiology Vol.52 No.12
Wheat germ agglutinin (WGA), which is secreted on thesurface of wheat root, has been defined as a protein that reversiblyand non-enzymatically binds to specific carbohydrates. However, little attention has been paid to the functionof WGA in the attachment of bacteria to their host plants. The aim of this study was to investigate the role of WGA inthe attachment of Pseudomonas sp. WS32 to wheat roots. Wheat roots were initially treated with double-distilled water,WGA-H (WGA solution that was heated at 100°C for 15 min)and WGA, independently. Subsequently, the roots were coincubatedwith cell solutions (109 cells/ml). A dilution platemethod using a solid nutrient medium was employed to determinethe adsorption of WS32 to wheat roots. WGA waslabeled with fluorescein isothiocyanate and detected usingthe fluorescent in situ hybridization (FISH) technique. Thenumber of adsorptive WS32 cells on wheat roots was significantlyincreased when the wheat roots were pretreatedwith WGA, compared with the control treatment (p = 0.01). However, WGA-H failed to increase the amount of bacterialcells that attached to the wheat roots because of the lossof its physiological activity. The FISH assay also revealedthat more cells adhered to WGA-treated wheat roots than tocontrol or WGA-H-treated roots. The results indicated thatWGA can mediate Pseudomonas strain WS32’s adherenceto wheat seedling roots. The findings of this study provide abetter understanding of the processes involved in plant-microbe interactions.

Karate is growing rapidly in China. As of 2021, 21 provinces, cities, and autonomous regions in China have established karate associations, and there are around 300,000-400,000 karate practitioners in China. However, little research has been done on the understanding and discussion of karate among the Chinese. This paper used literature review to reveal the Chinese perspectives on karate. The “karate” was used as a keyword to search relevant newspapers and articles in the People’s Daily and CNKI databases. Besides, books about karate from the National Library of China were compiled. The results showed that since the 1980s, the debate on karate has gradually emerged in China. From the 1980s to the 1990s, the Chinese have always held the understanding that karate originated from the Chinese martial arts of the Tang Dynasty. This understanding may have been brought into China by the Chinese who had been to Japan. However, this understanding is unreliable, and many Chinese martial art researchers accept this theory uncritically. Since 2010, with the introduction of karate majors in some Chinese universities, research on karate has increased rapidly. Chinese researchers have put forward a wide range of theories on the historical origin of karate by using the documents of China and Japan, such as Theory of the Thirty-six families from Min (久米三十六姓輸入説), Theory of development from Okinawan dance and so forth.
