The sensilla type, number and distribution in male and female adults of Carabus elysii Thomson, 1856 (Coleoptera: Carabidae) were studied using scanning electron microscopy. The results showed that there are seven categories and 12 types of sensilla in C. elysii adults: three types of S.Ch, three types of S.T, two types of S.B and one each of B.B, S.Co, S.Ca and S.Cam. There is no difference between male and female in the types of sensilla. Apart from the significant difference in the number and distribution of S.B.2, S.Co and S.Ca between male dorsal and ventral surfaces, there are no significant differences between male and female antennae. In general, the number of sensilla in females is larger than that in males. The results provide a basic reference for future ultrastructure, electrophysiological, and comparative behavioral studies of Carabus species.

최근 몇 년 회귀 주류와의 융합 교육 정책 하에 대만의 특수 교육 학교는 예전과 다른 큰 변화에 직면해 있다. 완전 융합 이념의 실시 또 심신장애학생을 주류교육으로 회귀해야 한다는 것을 제창함으로, 특수교육학교는 인원이 감소하게 됐다. 특수교육 학교는 신입생 모집이 부족한 상황에서 학교 교사들의 관점이 교장의 지도에 대해 보는 관점이 어떻게 다른가? 그에 대한 요구도 다른가? 본 연구는 두 인자 변의 수 분석이 대만 지능 장애와 감각 장애 종류의 특수 교육 학교 교장전형 리더십에 대한 연구이다. 실험 대상자는 8개 지능 장애종류 특수교육 학교와 5개 감각 장애종류 특수 교육 학교의 259명의 교사이고 그들이 특수교육학교 교장 리더에 대한 건의를 제출했다. In recent years, the domestic special education schools have faced with huge changes under the mainstream and inclusive education policies for the implementation of the full-inclusive and the mainstream education for the students with impairment. That causes the special education schools to reduce classes. Under this situation, what are the teachers?fdifferent views about the principal? What are their needs? The study was undertaken through two-way ANOVA to explore principals?ftransformational leadership between the schools for the mentally retarded and for the sensory impaired. 259 teachers were selected from 8 schools for the mentally retarded and 5 sensory impairment special education schools. Based upon the findings, the implications for practice were proposed.

The 55-km-long Hong Kong–Zhuhai–Macao Bridge (HZMB) is the world’s longest sea-crossing bridge, connecting Hong Kong with Zhuhai and Macao at the mouth of the Pearl River Estuary in China, comprising 22.9-km-long steel bridges. HZMB is the leading steel bridge in China, with top-level manufacturing and installation technology. This paper outlines the steel bridge construction experiences of HZMB to provide comparisons for the construction of other long sea-crossing steel bridges at home or abroad. The main considerations of construction constraints, scheme selection, structural and aesthetic design of HZMB are presented, and the following points related to new strategies in the steel bridge construction of HZMB are elaborated: (1) construction quality assurance, (2) automatic manufacturing technology, (3) large segment off shore installation, (4) eco-friendly paint (content limitation of volatile organic compounds) and new multifunctional inspection gantry, and (5) Guss Mastic Asphalt steel deck pavement system. The successful implementation of those strategies shows that the steel bridge construction of HZMB promotes improvement in the overall construction and management level of the Chinese bridge industry. The advanced experience of HZMB has opened up broad prospects for the design and construction of off shore bridge engineering in China.

Fang, Yuan,Li, Bin,Wang, Fang,Liu, Baoping,Wu, Zhiyi,Su, Ting,Qiu, Wen,Xie, Guanlin The Korean Society of Plant Pathology 2009 Plant Pathology Journal Vol.25 No.4
An unreported disease of apricot was observed in orchards in Zhejiang province, China. Symptoms started as water soaked lesions on the fruit surface. Later, water-soaked areas developed and spread to the entire fruit, resulting in soft rot of the whole fruit. The causal organism isolated from symptomatic fruits was identified as Burkholderia cepacia based on its biochemical and physiological characteristics and confirmed by the cellular fatty acid composition and Biolog data as well as 16S rRNA gene sequence analysis. The bacterial isolates caused similar symptoms when inoculated onto fruits of apricot. In addition, European plum, Japanese plum, nectarine and kiwifruit were susceptible to the B. cepacia pathogen. However, the B. cepacia pathogen failed to cause any visible symptoms when it was inoculated onto 16 other fruits. This is the first report of a bacterial disease of apricot caused by B. cepacia in China.

The over-expression of CHI3L1 has been identified in various types of malignancies, however the role of CHI3L1 in ovarian cancer is still unknown. We evaluated the feasibility of using CHI3L1 expression as a prognostic biomarker for patients with epithelial ovarian carcinoma. The possible biological functions of CHI3L1 in ovarian cancer were also elucidated. The expression levels of CHI3L1 in cancerous tissues were higher than those in normal tissues. The expression levels of CHI3L1 were also higher in the patients with a serous histological type, advanced stage, and chemo-resistance. The patients with a high CHI3L1 expression had significantly shorter progression-free survival and overall survival in Kaplan-Meier survival analysis. The patients with a high CHI3L1 expression also had a significant risk of recurrence and death in multivariate Cox regression analysis. In vitro studies showed that CHI3L1 up-regulated the expression of anti-apoptotic Mcl-1 protein and hampered paclitaxel-induced apoptosis of ovarian cancer cells. CHI3L1 shows potential as a prognostic biomarker for epithelial ovarian carcinoma. In addition, it may also promote chemo-resistance via inhibiting drug-induced apoptosis by up-regulating Mcl-1.

Purpose: To investigate and compare the effects of propofol and midazolam on inflammation and oxidase stress in children with congenital heart disease undergoing cardiac surgery. Materials and Methods: Thirty-two ASA class I-II children with congenital heart disease undergoing cardiac surgery were randomly divided into two groups: propofol combined with low dose fentanyl (PF group, n = 16) and midazolam combined with low dose fentanyl (MF group, n = 16). Tracheal extubation time and length of Intensive Care Unit (ICU) stay were recorded. Blood samples were taken before operation (T_0), at 2 h after release of the aorta cross-clamp (T_3) and at 24 h after operation (T_4) to measure interleukin 6 (IL-6), IL-8, superoxide dismutase (SOD) and malondialdehyde (MDA) levels. Myocardium samples were collected at 10-20 min after aorta cross-clamp (T_1) and at 10-20 min after the release of the aorta cross-clamp (T_2) to detect heme oxygenase-1 (HO-1) expression. Results: Tracheal extubation time and length of ICU stay in PF group were significantly shorter than those of the MF group (p < 0.05, respectively). After cardiopulmonary bypass, IL-6, IL-8 and MDA levels were significantly increased, and the SOD level was significantly reduced in both two groups, but PF group exhibited lower IL-6, IL-8 and MDA levels and higher SOD levels than the MF group (p < 0.05, respectively). The HO-1 expression in the PF group was significantly higher than that in MF group at the corresponding time points (p < 0.05, respectively). Conclusion: Propofol is superior to midazolam in reducing inflammation and oxidase stress and in improving post-operation recovery in children with congenital heart disease undergoing cardiac surgery.

Browning is one of the key factors that influenced the callus subculture of tree peony (Paeonia suffruticosa Andr.). Effects of medium composition and exogenous hormones: macro elements of Murashige and Skoog (MS salts) and iron salt (Fe2+), pH, agar and 6-benzylaminopurine (6-BA), 1-naphthaleneacetic acid (NAA) and kinetin (KT) on the callus browning of P. suffruticosa ‘Shan Hu Tai’ in vitro were studied in this paper. Results showed that the browning of P. suffruticosa callus were more sensitive to KT than 6-BA in different concentrations of 6-BA and KT separately with different concentrations of NAA, and reduced to the lowest (13.3%) under 0.5 mg·L-1 NAA plus 0.3 mg·L-1 KT. 1/4 × MS plus 1/4 × Fe2+ was the best basic medium in which the browning rate was only 18.2%. The browning rate of the callus was the lowest of 4.0% under pH 6.5 and the callus grew better in 7.0 g·L-1 agar than others. This study indicated that the best medium preventing P. suffruticosa callus in vitro from browning was: 1/4 × MS medium supplemented with 6.95 mg·L-1Fe2+, 0.3 mg·L-1 KT, 0.5 mg·L-1 NAA, 6.0 g·L-1 agar and 30 g·L-1 sucrose in pH 6.5.

Wen-Qing Du,Jian-An Sun,Juan-Fang Han,Wen-Shan Duan,Yang-Yang Yang,Xin Jiang 한국물리학회 2019 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.75 No.11
We investigated the head-on collision between two envelope solitary waves. Head-on collisions between two envelope solitary waves are first discussed in one-dimension (1D) granular chains. The interesting result is that no phase shift or phase delay detected after the head-on collision between two envelope solitary waves. The maximum amplitude during the head-on collision between two envelope solitary waves is also found to be less than the sum of the amplitudes of the two envelope solitary waves, but is larger than the amplitude of the either of the envelope solitary waves.
RESEARCH : Effects of repeated tuberculin skin testings on immune responses in experimental monkeys

Though many alternative methods to tuberculin skin testing (TST) have been established and evaluated in recent years, sensitivities and specificities of most methods could not meet the requirements of golden standards. In this study, we sought to identify whether repeated TSTs could affect the immune responses in experimental monkeys. Nine natural tuberculosis (TB) monkeys receiving repeated TSTs biweekly were used to demonstrate the effect on TST responsiveness. Two healthy monkeys were administrated with repeated TSTs to analyze the immune response profiling. Intrapalpebral reactions in TB infections gradually weakened or presented intermittent positive reactions. The leukocyte counts, cytokine responses, and antibody responses to all antigens except Old tuberculin (OT) and MPT64L showed no specific changes for TB in healthy monkeys. Positive antibody responses to OT and MPT64L emerged during the first half experimental period, which may cause by their cross-reactivity with mycobacterial species. Results showed that repeated TSTs had no significant effects on immune responses in healthy monkeys but a progressive reduction in TST responsiveness in TB infections.
