The aim of this study is to explore the correlations between fasciology and yin yang doctrine. Professor Yuan developed fasciology by three-dimensional reconstruction of connective tissue (fascia) in the trunk and limbs of the human body and tracing back to tissue origins in light of biological evolution and developmental biology. Fasciology states that the human body can be divided into two systems: the supporting-storing system and the functional system. This article elaborates on the roles of the two systems and their mutual relationship. The two systems are used to analyze the yin,the yang, and their relationship. The two systems are promoted but also restricted in different contexts. The supporting-storing system is formed by undifferentiated connective tissue and provides undifferentiated cells and nutrients for differentiated cells of the functional system. Thus, the supporting-storing system could be classified as quiet, similar to yin. The functional system continuously maintains the various functional activities of the human body. Thus, the functional system could be classified as active, similar to yang. In interpreting the yin yang doctrine from the point of view of fasciology, yin can be compared with the supporting-storing system and yang can be compared with the functional system.

Purpose: The aim of this study was to investigate effects of adipose-derived mesenchymal stem cells (AMSCs) on radioresistance of breast cancer cells. Materials and Methods: MTT assays were used to detect any influence of AMSC supernatants on proliferation of breast cancer cells; cell migration assays were used to determine the effect of breast cancer cells on the recruitment of AMSCs; the cell survival fraction post-irradiation was assessed by clonogenic survival assay; ${\gamma}$-H2AX foci number post-irradiation was determined via fluorescence microscopy; and expression of IGF-1R was detected by Western blotting. Results: AMSC supernatants promoted proliferation and radioresistance of breast cancer cells. Breast cancer cells could recruit AMSCs, especially after irradiation. IGF-1 derived from AMSCs might be responsible for the radioresistance of breast cancer cells. Conclusions: Our results suggest that AMSCs in the tumor microenvironment may affect the outcome of radiotherapy for breast cancer in vitro.

Chein-Hui-Yang,Chih-Neng Yang,Ying-Chieh Lee 한양대학교 세라믹연구소 2017 Journal of Ceramic Processing Research Vol.18 No.9

To improve the surface roughness of alumina substrates, the AlN precursor mixtures were coated on the alumina substrates. AlN precursor mixtures were coated on Al2O3 substrates using a sol-gel method. The AlN precursor mixtures were preparedusing urea, aluminum nitrate, sucrose and a surfactant. The effects of calcination temperature and soaking time on the phase evolution, microstructure, mechanical properties and surface roughness of the coating layer were investigated. The phase evolution, microstructure and constitution of the coating layer after calcination were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and electron spectroscopy for chemical analysis (ESCA). It was found that Al-N-O and Al2O3 phases can coexist at 1300 o C after soaking for ≤ 60 min in N2/H2 atmosphere. The adhesive strength ofcoating layer significantly increased with increasing calcination temperature. The surface roughness of Al2O3 substrates can be improved using AlN sol gel at 1300 oC. However, the surface roughness was obviously increased at 1500 o C.

Hui-Bo He,Hua-Ying Li,Jun Yang,Xian-Yin Zhang,Qi-Bin Yue,Xue Jiang,류성기 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.18 No.10

TiN coated and uncoated tools were used to conduct the dry cutting temperatures for AISI 304 stainless steel. Effects of cutting variables on cutting temperatures were investigated using single factor experiment method. The optimal cutting parameters of cutting temperatures were obtained through orthogonal experiment method. The forming process and temperature distribution of chips were analyzed using finite element method (FEM). The results show that cutting temperature generally increases with the increase of cutting speed and feed rate. When depth of cut increases at the range of 0.8-1.5 mm, the cutting temperature increases firstly and decreases subsequently. And the cutting temperature of TiN coated tool is lower than that of uncoated tool. The optimal parameters of cutting temperature are obtained by orthogonal experiment, which is A1B1C3. The highest temperature appears on the second deformation zone by the simulation.

Objectives. Some changes are found in the labyrinth anatomy during postnatal development. Although the spatial orientation of semicircular canals was thought to be stable after birth, we investigated the age-related orientational changes of human semicircular canals during development. Methods. We retrospectively studied the computed tomography (CT) images of both ears of 76 subjects ranged from 1 to 70 years old. They were divided into 4 groups: group A (1–6 years), group B (7–12 years), group C (13–18 years), and group D (>18 years). The anatomical landmarks of the inner ear structures were determined from CT images. Their coordinates were imported into MATLAB software for calculating the semicircular canals orientation, angles between semicircular canal planes and the jugular bulb (JB) position. Differences between age groups were analyzed using multivariate statistics. Relationships between variables were analyzed using Pearson analysis. Results. The angle between the anterior semicircular canal plane and the coronal plane, and the angle between the horizontal semicircular canal plane and the coronal plane were smaller in group D than those in group A (P<0.05). The JB position, especially the anteroposterior position of right JB, correlated to the semicircular canals orientation (P<0.05). However, no statistically significant differences in the angles between ipsilateral canal planes among different age groups were found. Conclusion. The semicircular canals had tendencies to tilt anteriorly simultaneously as a whole with age. The JB position correlated to the spatial arrangement of semicircular canals, especially the right JB. Our calculation method helps detect developmental and pathological changes in vestibular anatomy.

Methylated Alteration of SHP1 Complements Mutation of JAK2 Tyrosine Kinase in Patients with Myeloproliferative Neoplasm

Yang, Jun-Jun,Chen, Hui,Zheng, Xiao-Qun,Li, Hai-Ying,Wu, Jian-Bo,Tang, Li-Yuan,Gao, Shen-Meng Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.6

SHP1 negatively regulates the Janus kinase 2/signal transducer and activator of transcription (JAK2/STAT) signaling pathway, which is constitutively activated in myeloproliferative neoplasms (MPNs) and leukemia. Promoter hypermethylation resulting in epigenetic inactivation of SHP1 has been reported in myelomas, leukemias and other cancers. However, whether SHP1 hypermethylation occurs in MPNs, especially in Chinese patients, has remained unclear. Here, we report that aberrant hypermethylation of SHP1 was observed in several leukemic cell lines and bone marrow mononuclear cells from MPN patients. About 51 of 118 (43.2%) MPN patients including 23 of 50 (46%) polycythaemia vera patients, 20 of 50 (40%) essential thrombocythaemia and 8 of 18 (44.4%) idiopathic myelofibrosis showed hypermethylation by methylation-specific polymerase chain reaction. However, SHP1 methylation was not measured in 20 healthy volunteers. Hypermethylation of SHP1 was found in MPN patients with both positive (34/81, 42%) and negative (17/37, 45.9%) JAK2V617F mutation. The levels of SHP1 mRNA were significantly lower in hypermethylated samples than unmethylated samples, suggesting SHP1 may be epigenetically inactivated in MPN patients. Furthermore, treatment with 5-aza-2'-deoxycytidine (AZA) in K562 cells showing hypermethylation of SHP1 led to progressive demethylation of SHP1, with consequently increased reexpression of SHP1. Meanwhile, phosphorylated JAK2 and STAT3 were progressively reduced. Finally, AZA increased the expression of SHP1 in primary MPN cells with hypermethylation of SHP1. Therefore, our data suggest that epigenetic inactivation of SHP1 contributes to the constitutive activation of JAK2/STAT signaling. Restoration of SHP1 expression by AZA may contribute to clinical treatment for MPN patients.

Thermoelectric multilayer thin films used in nanoscale energy conversion have been receiving increasing attention in both academic research and industrial applications. Thermal transport across multilayer interface plays a key role in improving thermoelectric conversion efficiency. In this study, the cross-plane thermal conductivities of nano-constructed Sb2Te3/(Cu, Ag, Au, Pt) thermoelectric multilayer thin films have been measured using time-domain thermoreflectance method. The interface morphology features of multilayer thin film samples were characterized by using scanning and transmission electron microscopes. The effects of interface microstructure on the cross-plane thermal conductivities of the multilayer thin films have been extensively examined and the thermal transfer mechanism has been explored. The results indicated that electron–phonon coupling occurred at the semiconductor/metal interface that strongly affected the cross-plane thermal conductivity. By appropriately optimizing the period thickness of the metal layer, the cross-plane thermal conductivity can be effectively reduced, thereby improving the thermoelectric conversion efficiency. This work presents both experimental and theoretical understanding of the thermal transport properties of Sb2Te3/metal multilayer thin film junctions with important implications for exploring a novel approach to improving the thermoelectric conversion efficiency.

Hui-ying Fu,Xiao-tong Ye,Gao-yu Zhong,Zhi-yang Zhong,Fei Xiao 한국물리학회 2010 Current Applied Physics Vol.10 No.5

This paper describes the white organic light-emitting diodes (WOLEDs) made from a benzothiazole derivative, N-(4-(benzo[d]thiazol-2-yl)phenyl)-N-phenylnaphthalen-1-amine (BPNA). The bright yellowish-white emission was obtained from a non-doped triple-layer device: ITO/NPB (40 nm)/BPNA (50 nm)/Alq3 (40 nm)/LiF/Al. The Commission Internationale de L’Eclairage (CIE) coordinates of the device were (0.24, 0.36) at 10 V. The maximum brightness of the device was 9225 cd/㎡ at 14.4 V. A current efficiency of 3.08 cd/A, a power efficiency of 1.21 lm/W and an external quantum efficiency of 1.18% at a driving current density of 20 mA/㎠ were achieved. WOLED with a DCJTB-doped structure of ITO/TcTa/BPNA/BPNA: DCJTB (0.5%)/BPNA/BCP/Alq3/LiF/Al was fabricated in comparison with the non-doped device. The device emitted bright white light with the CIE coordinates of (0.33, 0.29) at 10 V and a maximum luminance of 7723 cd/㎡ at 14.8 V.

Appropriate Soil Heat Treatment Promotes Growth and Disease Suppression of Panax notoginseng by Interfering with the Bacterial Community

( Ying-bin Li ),( Zhi-ping Zhang ),( Ye Yuan ),( Hui-chuan Huang ),( Xin-yue Mei ),( Fen Du ),( Min Yang ),( Yi-xiang Liu ),( Shu-sheng Zhu ) 한국미생물 · 생명공학회 2022 Journal of microbiology and biotechnology Vol.32 No.3

In our greenhouse experiment, soil heat treatment groups (50, 80, and 121°C) significantly promoted growth and disease suppression of Panax notoginseng in consecutively cultivated soil (CCS) samples (p < 0.01), and 80°C worked better than 50°C and 121°C (p < 0.01). Furthermore, we found that heat treatment at 80°C changes the microbial diversity in CCS, and the inhibition ratios of culturable microorganisms, such as fungi and actinomycetes, were nearly 100%. However, the heat-tolerant bacterial community was preserved. The 16S rRNA gene and internal transcribed spacer (ITS) sequencing analyses indicated that the soil heat treatment had a greater effect on the Chao1 index and Shannon’s diversity index of bacteria than fungi, and the relative abundances of Firmicutes and Proteobacteria were significantly higher than without heating (80 and 121°C, p < 0.05). Soil probiotic bacteria, such as Bacillus (67%), Sporosarcina (9%), Paenibacillus (6%), Paenisporosarcina (6%), and Cohnella (4%), remained in the soil after the 80°C and 121°C heat treatments. Although steam increased the relative abundances of most of the heat-tolerant microbes before sowing, richness and diversity gradually recovered to the level of CCS, regardless of fungi or bacteria, after replanting. Thus, we added heat-tolerant microbes (such as Bacillus) after steaming, which reduced the relative abundance of pathogens, recruited antagonistic bacteria, and provided a long-term protective effect compared to the steaming and Bacillus alone (p < 0.05). Taken together, the current study provides novel insight into sustainable agriculture in a consecutively cultivated system.

Impact of the Silicon-nitride Passivation Film Thickness on the Characteristics of InAlAs/InGaAs InP-based HEMTs

Ying-Hui Zhong,Jie Yang,Xin-Jian Li,Peng Ding,Zhi Jin 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.66 No.6

In this research, the DC and RF characteristics for our own InAlAs/InGaAs InP-based highelectron-mobility transistors (HEMTs) with 0-nm, 50-nm, and 200-nm silicon-nitride (Si3N4) passivationfilms have been investigated comprehensively and systematically. With increasing Si3N4passivation film thickness, the device exhibits an apparent improvement in the output conductanceand a distinct drift of the pinch-off voltage toward a positive value. Especially, the device passivatedby using a 50-nm Si3N4 film demonstrates the highest extrinsic transconductance and channelcurrent. The appeared changes of the DC properties can be interpreted as due to the passivationinducedpositively-charged surface state increasing the sheet carrier density with the carrier mobilityand parasitic resistance of device being deteriorated by long-time high-stress-intensity ion bombardment. Additionally, the degradations of the current-gain cutoff frequency (fT ) and maximumoscillation frequency (fmax) can be attributed to the drastically-increased parasitic capacitance andresistance induced by the passivation process. This work will be of great importance in fabricatingInP HEMTs with high performances.
