        Description of Ornithinimicrobium cryptoxanthini sp. nov., a Novel Actinomycete Producing β-cryptoxanthin Isolated from the Tongtian River Sediments

        Huang Yuyuan,Jiao Yifan,Zhang Sihui,Tao Yuanmeihui,Zhang Suping,Jin Dong,Pu Ji,Liu Liyun,Yang Jing,Lu Shan 한국미생물학회 2023 The journal of microbiology Vol.61 No.4

        Two novel Gram-stain-positive, aerobic, non-motile, and yellow-pigmented, irregular rod-shaped bacteria (JY.X269 and JY.X270T) were isolated from the near-surface sediments of river in Qinghai Province, P. R. China (32°37′13″N, 96°05′37″E) in July 2019. Both strains were shown to grow at 15–35 °C and pH 7.0–10.0, and in the presence of 0–6.0% (w/v) NaCl. The 16S rRNA gene sequence analysis showed that the isolates were closely related to Ornithinimicrobium cavernae CFH 30183 T (98.6–98.8% 16S rRNA gene sequence similarity), O. ciconiae H23M54T (98.5–98.6%) and O. murale 01-Gi-040T (98.3–98.5%). The phylogenetic and phylogenomic trees based on the 16S rRNA gene and 537 core gene sequences, respectively, revealed that the two strains formed a distinct cluster with the above three species. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between our two isolates (JY.X269 and JY.X270T) and other Ornithinimicrobium species were within the ranges of 19.0–23.9% and 70.8–80.4%, respectively, all below the respective recommended 70.0% and 95–96% cutoff point. Furthermore, the major cellular fatty acids (> 10.0%) of strains JY.X269 and JY.X270T were iso-C15:0, iso-C16:0, and summed feature 9. Strain JY.X270T contained MK-8(H4) and ornithine as the predominant menaquinone and diagnostic diamino acid component within the cell wall teichoic acids. β-cryptoxanthin ( C40H56O) can be extracted from strain JY.X270T, and its content is 6.3 μg/ml. Based on results from the phylogenetic, chemotaxonomic, and phenotypic analyses, the two strains could be classified as a novel species of the genus Ornithinimicrobium, for which the name Ornithinimicrobium cryptoxanthini sp. nov. is proposed (type strain JY.X270T = CGMCC 1.19147T = JCM 34882T).

        Adsorption Kinetics and Thermodynamics of Water-Insoluble Crosslinked β-Cyclodextrin Polymer for Phenol in Aqueous Solution

        Hui Huang,Yifan Fan,Junwei Wang,Haoqi Gao,Shiying Tao 한국고분자학회 2013 Macromolecular Research Vol.21 No.7

        A water-insoluble β-cyclodextrin (β-CD) polymer was synthesized by reacting β-CD with hexamethylene diisocyanate, and its adsorption kinetics and thermodynamics for phenol from aqueous solution was investigated. The kinetics of adsorption followed the pseudo-second-order model and the adsorption isotherms could be well fitted by the Freundlich adsorption equation. The values of thermodynamic parameters demonstrated that the adsorption was a physisorption in a spontaneous and exothermic process.

        Changpingibacter yushuensis gen. nov., sp. nov., isolated from fluvial sediment in Qinghai Tibet Plateau of China

        Jiao Yifan,Zhang Sihui,Yang Jing,Lai Xin-He,Dong Kui,Cheng Yanpeng,Xu Mingchao,Zhu Wentao,Lu Shan,Jin Dong,Pu Ji,Huang Ying,Liu Liyun,Wang Suping,Xu Jianguo 한국미생물학회 2022 The journal of microbiology Vol.60 No.2

        Two facultatively anaerobic, short rod-shaped, non-motile, Gram-stain-positive, unknown bacterial strains (JY-X040T and JY-X174) were isolated from fluvial sediments of Tongtian River in Yushu Tibetan Autonomous Prefecture, Qinghai province, China. Cells formed translucent, gray, round and convex colonies, with a diameter of less than 0.5 mm after 5 days of incubation at 30°C on brain heart infusion-5% sheep blood agar. The 16S rRNA gene sequence similarity between strain JY-X040T and Fudania jinshanensis 313T is 93.87%. In the four phylogenetic trees constructed based on the 16S rRNA gene and 423 core genes, the two isolates form an independent branch, phylogenetically closest to F. jinshanensis 313T, but could not be classified as a member of the genus Fudania or any other genus of the family Arcanobacteriaceae. The DNA G + C content of strain JY-X040T was 57.8%. Calculation results of average nucleotide identity, digital DNADNA hybridization value and amino acid identity between strain JY-X040T and F. jinshanensis 313T are 69.9%, 22.9%, and 64.1%. The major cellular fatty acids were C16:0 (23%) and C18:1ω9c (22%). The cell-wall peptidoglycan type was A5α (L-Lys-L-Ala-L-Lys-D-Glu). The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and four unidentified components. The whole-cell sugars contained rhamnose and ribose. MK-10(H4) was the sole respiratory quinone. The minimum inhibitory concentration of streptomycin was 32 μg/ml. All physiological, biochemical, chemotaxonomic and genomic characteristics support that strains JY-X040T and JY-X174 represent members of a novel species in a new genus, Changpingibacter yushuensis gen. nov., sp. nov. The type strain is JY-X040T (GDMCC 1.1996T = KCTC 49514T).

      • Hierarchical fault propagation of command and control system

        Tingyu Zhang,Hong-Zhong Huang,Yifan Li,Sizhe Huang,Yahua Li 국제구조공학회 2022 Smart Structures and Systems, An International Jou Vol.29 No.6

        A complex system is comprised of numerous entities containing physical components, devices and hardware, events or phenomena, and subsystems, there are intricate interactions among these entities. To reasonably identify the critical fault propagation paths, a system fault propagation model is essential based on the system failure mechanism and failure data. To establish an appropriate mathematical model for the complex system, these entities and their complicated relations must be represented objectively and reasonably based on the structure. Taking a command and control system as an example, this paper proposes a hierarchical fault propagation analysis method, analyzes and determines the edge betweenness ranking model and the importance degree of each sub-system.

        Cell-Penetrating Peptide-Modified PLGA Nanoparticles for Enhanced Nose-to-Brain Macromolecular Delivery

        Lu Yan,Huiyuan Wang,Yifan Jiang,Jinhua Liu,Zhao Wang,Yongxin Yang,Shengwu Huang,Yongzhuo Huang 한국고분자학회 2013 Macromolecular Research Vol.21 No.4

        Macromolecular drugs become an essential part in neuroprotective treatment. However, the nature of ineffective delivery crossing the blood brain barrier (BBB) renders those macromolecules undruggable for clinical practice. Recently, brain target via intranasal delivery have provided a promising solution to circumventing the BBB. Despite the direct route from nose to brain (i.e. olfactory pathway), there still are big challenges for large compounds like proteins to overcome the multiple delivery barriers such as nasal mucosa penetration, intracellular transport along the olfactory neuron, and diffusion across the heterogeneous brain compartments. Herein presented is an intranasal strategy mediated by cell-penetrating peptide modified poly(lactic-co-glycolic acid) (PLGA) nanoparticles for the delivery of insulin to the brain, a potent therapeutic against Alzheimer’s disease. The results revealed that the cell-penetrating peptide can potentially deliver insulin into brain via the nasal route, showing a total brain delivery efficiency of 6%. It could serve as a potential treatment for neurodegenerative diseases.

        IMPROVED HYBRID A-STAR ALGORITHM FOR PATH PLANNING IN AUTONOMOUS PARKING SYSTEM BASED ON MULTI-STAGE DYNAMIC OPTIMIZATION

        Meng Tianchuang,Yang Tianhong,Huang Jin,Jin Wenrui,Zhang Wei,Jia Yifan,Wan Keqian,Xiao Gang,Yang Diange,Zhong Zhihua 한국자동차공학회 2023 International journal of automotive technology Vol.24 No.2

        The recent proliferation of intelligent technologies has promoted autonomous driving. The autonomous parking system has become a popular feature in autonomous driving. Hybrid A-star algorithm is a commonly used path planning algorithm for its simplicity to deploy and the good characteristics of the generated paths in the practical engineering. To further enhance the path safety and efficiency of path planning in the autonomous parking system, this paper proposes an improved hybrid A-star algorithm through the safety-enhanced design and the efficiency-enhanced design. The safety-enhanced design integrates the Voronoi field potential into the path searching stage to take more account of path safety. The efficiency-enhanced design proposes a multi-stage dynamic optimization strategy which divides the path planning into multiple stages and performs dynamic optimization in each stage. Through simulation experiments, it is verified that the proposed improved algorithm not only generates a much safer path which stays farther from the obstacles but also significantly improves the searching efficiency in terms of time and space, merely at a finite cost of pre-processing work which can also be repeatedly utilized. We hope this paper will promote relative research on path planning in autonomous parking and serve as a reference for the practical engineering.

        Iterative self-transfer learning: A general methodology for response time-history prediction based on small dataset

        Xu Yongjia,Lu Xinzheng,Fei Yifan,Huang Yuli 한국CDE학회 2022 Journal of computational design and engineering Vol.9 No.5

        There are numerous advantages of deep neural network surrogate modeling for response time-history prediction. However, due to the high cost of refined numerical simulations and actual experiments, the lack of data has become an unavoidable bottleneck in practical applications. An iterative self-transfer learning method for training neural networks based on small datasets is proposed in this study. A new mapping-based transfer learning network, named as deep adaptation network with three branches for regression (DAN-TR), is proposed. A general iterative network training strategy is developed by coupling DAN-TR and the pseudo-label strategy, and the establishment of corresponding datasets is also discussed. Finally, a complex component is selected as a case study. The results show that the proposed method can improve the model performance by near an order of magnitude on small datasets without the need of external labeled samples, well behaved pre-trained models, additional artificial labeling, and complex physical/mathematical analysis.

        The Heterogeneity of Ovomucoid-Specific IgE Idiotype Is Associated With Egg Allergy Symptom Severity

        Li Liuxu,Zhang Bei,Li Yifan,Huang Lunhui,Li Shaoshen,Liu Dandan,Yu Yang,Li Huiqiang 대한천식알레르기학회 2023 Allergy, Asthma & Immunology Research Vol.15 No.1

        Immunoglobulin E (IgE)-mediated egg allergy presents as one of the most common food allergies. The level of specific IgE (sIgE) antibody is widely used as an important in vitro diagnostic indicator. However, sIgE antibody levels are often inconsistent with the clinical manifestations of patients. The heterogeneity of egg-specific IgE idiotypes (sIgE-IDs) may help reflect clinical egg allergy severity. Eight peptides were synthesized, corresponding to the linear epitopes of ovomucoid (OVM). The sIgE-IDs of egg-allergic patients were detected by enzyme-linked immunosorbent assay. Fresh peripheral blood was collected from patients with different heterogeneity strength of sIgE-ID, and egg extract was used as a stimulus to the basophil activation test (BAT). RBL-2H3 cells were sensitized with serum with different strength of sIgE-ID heterogeneity and the release rate of β-hexosaminidase was calculated. Among 75 patients with egg allergy, 24% had sIgE for all epitopes and 85% had sIgE for at least one epitope. Analysis of individual patients revealed differences in epitope recognition patterns among the patients, that is, heterogeneity in sIgE-ID. More importantly, the number of IgE-positive peptides had a strong correlation with allergic symptoms in egg-allergic patients (r = 0.706). BAT and RBL-2H3 cell degranulation confirmed that higher sIgE-ID heterogeneity strength was more effective in inducing effector cell responses. Our results suggest that the greater the heterogeneity strength of OVM-sIgE-ID, the more severe the allergic symptoms.
