박지원 등이 창조한 건륭황제의 형상은 '객관화'됨으로써 동시대와 후세의 조선인들이 건륭황제를 묘사하는 데 있어서 원초적인 경험을 제공해주는 '기본 텍스트'로 작용하여 왔고 앞으로도 장기간에 걸쳐 건륭황제와 그 가족을 해석하는 기틀로 작용하게 될 것이다. 박지원이 묘사한 건륭황제는 조선조시기라는 역사적인 배경에서 이루어진 것인 동시에 박지원은 또한 조선조시기라는 역사적인 배경을 이루는 한 요소이기도 하다. 다시 말하면 사회집단의 상상력과 텍스트 사이의 관계는 전자가 후자를 제약하는 단선적인 영향관계가 아니라 양자가 서로 영향주는 관계, 일종의 교호적인 대화과정에 처해 있으며 부단한 대화과정에서 끊임없이 새로운 의의가 생성되고 새로운 형상이 탄생하게 되는 것이다. The objective image of Emperor Qianlong created by Pak Chi-Won is regarded as the pre-interpretation of the emperor. Such an image not only made the foundation for those Koreans in the same and following periods but also constrained the followers' interpretation of Qianlong and his family for a long time. Though the interpretation of Qianlong by Pak Chi-Won was constrained in the context of Li Dynasty, his interpretation also contributed to the creation of the context. It means the relation between virtual world of the community and text is not that the former one influences and constrains the later one but they interact with each other. They have an iterative dialogue relation. In such iterative dialogues new meanings and new images are continuously created.

( Guang Ze Jin ),( Liang Liu ),( Zhi Li Liu ),( Ji Hong Kim ) 한국임학회 2010 한국산림과학회지 Vol.99 No.5

On the basis of vegetation data in the 9.12 ha (380 m×240 m) permanent sample plot of the spruce-fir valley forest in Liangshui National Reserve of Xiaoxing`an Mountains, the study was conducted to evaluate spatial distribution pattern and spatial association by using point pattern analysis for living and dead trees of Larix gmelini by DBH size class. The number of L. gmelini were counted as 59 living stems/ha (6.42 m2/ha of basal area) and 34 dead stems/ha (2.86 m2/ha of basal area). The distributional curve of diameter class exhibited bimodal shape. The analysis of spatial distribution patterns of all living larch stems noted the clumped distribution on the whole. The size of larch aggregates of dead stems was decreased as diameter class was increased. The distribution of dead stems became gradually randomized with decreased clumped size as the scale increased. Living stems and dead stems of the larch had positive spatial association at most of scales, illustrating that the occurrence of mortality of the larch tree was closely related to the distribution pattern of living larch trees.

Purpose: The molecular links between metabolism and inflammation that drive different inflammatory phenotypes in asthma are poorly understood. We aimed to identify the metabolic signatures and underlying molecular pathways of different inflammatory asthma phenotypes. Methods: In the discovery set (n = 119), untargeted ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS) was applied to characterize the induced sputum metabolic profiles of asthmatic patients with different inflammatory phenotypes using orthogonal partial least-squares discriminant analysis (OPLS-DA), and pathway topology enrichment analysis. In the validation set (n = 114), differential metabolites were selected to perform targeted quantification. Correlations between targeted metabolites and clinical indices in asthmatic patients were analyzed. Logistic and negative binomial regression models were established to assess the association between metabolites and severe asthma exacerbations. Results: Seventy-seven differential metabolites were identified in the discovery set. Pathway topology analysis uncovered that histidine metabolism, glycerophospholipid metabolism, nicotinate and nicotinamide metabolism, linoleic acid metabolism as well as phenylalanine, tyrosine and tryptophan biosynthesis were involved in the pathogenesis of different asthma phenotypes. In the validation set, 24 targeted quantification metabolites were significantly expressed between asthma inflammatory phenotypes. Finally, adenosine 5′-monophosphate (adjusted relative risk [adj RR] = 1.000; 95% confidence interval [CI] = 1.000–1.000; P = 0.050), allantoin (adj RR = 1.000; 95% CI = 1.000–1.000; P = 0.043) and nicotinamide (adj RR = 1.001; 95% CI = 1.000–1.002; P = 0.021) were demonstrated to predict severe asthma exacerbation rates. Conclusions: Different inflammatory asthma phenotypes have specific metabolic profiles in induced sputum. The potential metabolic signatures may identify therapeutic targets in different inflammatory asthma phenotypes.

Application of rare earth as mordant for the dyeing of ramie fabrics with natural dyes

Guang Hong Zheng,Hong Bin Fu,Guang Ping Liu 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.11

Selecting appropriate metallic compounds as mordants is essential for dyeing with natural dyes. This paper presents the application of rare earth compounds as mordant for the dyeing of ramie fabrics with four kinds of natural dyes. The influences of pre-mordanting, simultaneous mordanting, and post-mordanting on the dyeing effect were explored. The post-mordanting was proved to give rise to the highest dye uptake. The effects of dyeing conditions including dyeing temperature and time, dyeing bath pH and the concentration of rare earth on the dye uptake were investigated systematically. The fabrics dyed with natural dyes in presence of rare earth as mordant exhibited high color shade stability in the baths with pH varying from being acidic to neutral and alkaline. Employing rare earth as mordant apparently raised the color fastness to washing, rubbing and light of the ramie fabrics dyed with the natural extracts. In comparison with the commonly used metallic salts, using rare earth chlorides as mordants can greatly reduce the ionic concentration employed in natural dyeing. This study proved that rare earth would be a kind or promising environmentally friendly mordant in natural dyeing.

<P>A Gram-stain-negative, rod-shaped bacterium (strain Hh36<SUP>T</SUP>) was isolated from the No. 1 glacier in Xinjiang, north-west China. Colonies of strain Hh36<SUP>T</SUP> were pink, convex and round on PYG medium plates. Strain Hh36<SUP>T</SUP> was able to grow at 4–30 °C and pH 6.0–8.0. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Hh36<SUP>T</SUP> was related to members of the genus <I>Arcticibacter</I>. The major cellular fatty acids of the novel strain were iso-C<SUB>15 : 0</SUB>, summed feature 3 (C<SUB>16 : 1</SUB>ω6<I>c</I> and/or C<SUB>16 : 1</SUB>ω7<I>c</I>) and iso-C<SUB>17 : 0</SUB> 3-OH. The G+C content of the genomic DNA was 44.0 mol%. On the basis of phenotypic characteristics and phylogenetic analysis, strain Hh36<SUP>T</SUP> is considered to represent a novel species of the genus <I>Arcticibacter</I>, for which the name <I>Arcticibacter</I> <I>pallidicorallinus</I> sp. nov. is proposed. The type strain is Hh36<SUP>T</SUP> ( = CGMCC 1.9313<SUP>T</SUP> = KCTC 32542<SUP>T</SUP>).</P>

Guang-Yu Yang,Jia-Meng Dai,Zhen-Jie Li,Jin Wang,Feng-Xian Yang,Xin Liu,Jing Li,Qian Gao,Xue-Mei Li,Yin-Ke Li,Wei-Guang Wang,Min Zhou,Qiu-Fen Hu 대한약학회 2022 Archives of Pharmacal Research Vol.45 No.8

In previous studies, several isoindolin-1-oneanalogs that exhibited signifi cant anti-tobacco mosaic virus(anti-TMV) activities were isolated from Nicotiana tabacum . Since gene-editing mutants provide a new sample for thediscovery of active metabolites, we focused on the stems ofYN-18–23 (a mutant N. tabacum for gene editing with thealkaloid metabolic pathway cultivated by Yunnan TobaccoCompany), which led to the isolation of four new ( 1–4 )and four known ( 5–8 ) isoindolin-1-ones. To the best of ourknowledge, nicindole C ( 3 ) is the fi rst subclass of isoindolin-1-one bearing a pentacyclic ketone, while nicindole D ( 4 )is the fi rst example of isoindolin-1-one bearing a methylpyridin-2-(1 H )-one moiety. Compounds 1–4 were testedfor their anti-TMV activities, and the results revealed thatcompounds 1 , 3 , and 4 exhibited high anti-TMV activities atconcentrations of 20 μM with inhibition rates of 48.6, 42.8,and 71.5%, respectively. These rates are higher than the inhibitionrate of the positive control (33.2%). The mechanisticstudy of compound 4 , which had the highest anti-TMV activityrevealed that increased potentiation of defense-related enzyme activities and downregulation of expression of theNtHsp70 protein may induce resistance in tobacco againstthe viral pathogen TMV. Molecular docking studies alsorevealed that the isoindolin-1-one substructure is fundamentalfor anti-TMV activity. The methyl-pyridin-2-(1 H )-onemoiety in compound 4 and the 2-oxopropyl groups in compounds1 and 3 at the N -2 position may increase inhibitoryactivities. This study of the structure–activity relationshipis helpful for fi nding new anti-TMV activity inhibitors. Tostudy whether the isoindolin-1-ones have broader antiviralactivities, compounds 1–4 were also tested for their antirotavirusactivities. Compound 4 exhibited high anti-rotavirusactivity with a therapeutic index (TI) value of 20.7. This TI value is close to that of the positive control (20.2).

Guang Fang Zhou,Qing Tao Liu,Bin Zhou,Ya Feng Qiu,Xiao Dong Liu,Zhi Yong Ma,Xiu Li Feng,Rui Bing Cao,Pu Yan Chen 대한수의학회 2015 Journal of Veterinary Science Vol.16 No.3

The bursa of Fabricius (BF) is the acknowledged central humoral immune organ in birds. Bursal septpeptide II (BSP-II) is animmunomodulatory bioactive peptide isolated from BF. To understand the effects of BSP-II on immune induction, gene expression profilesof hybridoma cells treated with BSP-II were evaluated. Pathway analysis showed that regulated genes were involved in cytokine-cytokinereceptor interactions, T cell receptor signaling pathway, and pathway in cancer. It was observed that BSP-II reduced tumor cells proliferationand stimulated p53 expression. These results indicate potential mechanisms underlying the effects of the humoral immune system on immuneinduction, including antitumor activities. Our study has provided a novel insight into immunotherapeutic strategies for treating human tumors.

Deep Brain Stimulation of the Subthalamic and Pedunculopontine Nucleus in a Patient with Parkinson's Disease

Liu, Huan-Guang,Zhang, Kai,Yang, An-Chao,Zhang, Jian-Guo The Korean Neurosurgical Society 2015 Journal of Korean neurosurgical society Vol.57 No.4

Deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) is a novel therapy developed to treat Parkinson's disease. We report a patient who underwent bilateral DBS of the PPN and subthalamic nucleus (STN). He suffered from freezing of gait (FOG), bradykinesia, rigidity and mild tremors. The patient underwent bilateral DBS of the PPN and STN. We compared the benefits of PPN-DBS and STN-DBS using motor and gait subscores. The PPN-DBS provided modest improvements in the gait disorder and freezing episodes, while the STN-DBS failed to improve the dominant problems. This special case suggests that PPN-DBS may have a unique role in ameliorating the locomotor symptoms and has the potential to provide improvement in FOG.
