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.

<P>Natural rubber (<I>cis</I>-1,4-polyisoprene) is an indispensable biopolymer used to manufacture diverse consumer products. Although a major source of natural rubber is the rubber tree (<I>Hevea brasiliensis</I>), lettuce (<I>Lactuca sativa</I>) is also known to synthesize natural rubber. Here, we report that an unusual <I>cis</I>-prenyltransferase-like 2 (<I>CPTL2</I>) that lacks the conserved motifs of conventional <I>cis</I>-prenyltransferase is required for natural rubber biosynthesis in lettuce. <I>CPTL2</I>, identified from the lettuce rubber particle proteome, displays homology to a human NogoB receptor and is predominantly expressed in latex. Multiple transgenic lettuces expressing <I>CPTL2-RNAi</I> constructs showed that a decrease of <I>CPTL2</I> transcripts (3–15% <I>CPTL2</I> expression relative to controls) coincided with the reduction of natural rubber as low as 5%. We also identified a conventional <I>cis</I>-prenyltransferase 3 (<I>CPT3</I>), exclusively expressed in latex. In subcellular localization studies using fluorescent proteins, cytosolic CPT3 was relocalized to endoplasmic reticulum by co-occurrence of CPTL2 in tobacco and yeast at the log phase. Furthermore, yeast two-hybrid data showed that CPTL2 and CPT3 interact. Yeast microsomes containing CPTL2/CPT3 showed enhanced synthesis of short <I>cis</I>-polyisoprenes, but natural rubber could not be synthesized <I>in vitro</I>. Intriguingly, a homologous pair CPTL1/CPT1, which displays ubiquitous expressions in lettuce, showed a potent dolichol biosynthetic activity <I>in vitro</I>. Taken together, our data suggest that CPTL2 is a scaffolding protein that tethers CPT3 on endoplasmic reticulum and is necessary for natural rubber biosynthesis <I>in planta</I>, but yeast-expressed CPTL2 and CPT3 alone could not synthesize high molecular weight natural rubber <I>in vitro</I>.</P>
A Scalable Message Authentication Scheme for JPEG2000 Codestreams
Yang Qu,Chae Duk Jung,Kyung Hyune Rhee 한국멀티미디어학회 2008 한국멀티미디어학회 학술발표논문집 Vol.2008 No.1
Most scalable authentication schemes for images proposed in literature only consider about general signature schemes which use an unkeyed one-way hash function to generate hash digest. In this paper, we propose a scalable message authentication scheme for JPEG2000 codestream utilizing a keyed hash function to provide both integrity and origin authentication. The proposed scheme adapts the Merkle hash tree-based authentication in [3], combining with a flexible packet’s secret key generation for message authentication codes. Moreover, the properties of JPEG2000 codestream structure are completely maintained in our proposed authentication scheme.

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.

We wanted to know whether K-ROD (KD) internal fixation system could ameliorate lumbar adjacent segment degeneration (LASD) diseases. From May 2010 to May 2012, 66 patients with lumbar LASD were repaired via KD system. The outcome for LASD was analyzed using visual analogue scale (VAS), Oswestry disability index (ODI) and the 36-Item Short Form Health Survey. Meanwhile, range of motion (ROM) of total lumbar and dynamic fixation segments were also examined. Twelve patients inquired the removal of KD system because of fatigue during the first year after surgery. For remaining patients, the mean VAS score for back pain was 45.2±28.7 before operation, and decreased to 22.3±14.2 after two-year surgery (p<0.01); meanwhile, the mean ODI score was decreased from 76.5±11.2% to 21.1±5.4% (p<0.01). SF-36 parameters were significantly improved compared with those acquired the removal of KD system (p<0.01). Total 45 patients restored flexion-extension ROM after surgery (p<0.01). More than 80% disc generation was improved by KD system. KD system is an effective therapeutic way for treating LASD patients. The dynamic stabilization system preserves the motion of fixation segment and provides an alternative for therapy of lumbar LASD.
Behavior of three-tube buckling-restrained brace with circumference pre-stress in core tube
Yang Li,Haiyan Qu,Shaowen Xiao,Peijun Wang,Yang You,Shuqing Hu 국제구조공학회 2019 Steel and Composite Structures, An International J Vol.30 No.2
The behavior of a new Three-Tube Buckling-Restrained Brace (TTBRB) with circumference pre-stress (σθ,pre) in core tube are investigated through a verified finite element model. The TTBRB is composed of one core tube and two restraining tubes. The core tube is in the middle to provide the axial stiffness, to carry the axial load and to dissipate the earthquake energy. The two restraining tubes are at inside and outside of the core tube, respectively, to restrain the global and local buckling of the core tube. Based on the yield criteria of fringe fiber, a design method for restraining tubes is proposed. The applicability of the proposed design equations are verified by TTBRBs with different radius-thickness ratios, with different gap widths between core tube and restraining tubs, and with different levels of σθ,pre. The outer and inner tubes will restrain the deformation of the core tube in radius direction, which causes circumference stress (σθ) in the core tube. Together with the σθ,pre in the core tube that is applied through interference fit of the three tubes, the yield strength of the core tube in the axial direction is improved from 160 MPa to 235 MPa. Effects of gap width between the core tube and restraining tubes, and σθ,pre on hysteretic behavior of TTBRBs are presented. Analysis results showed that the gap width and the σθ,pre can significantly affect the hysteretic behavior of a TTBRB.

316L stainless steel specimens were manufactured by additive/subtractive hybrid manufacturing (ASHM). The densification level, microstructure, microhardness and residual stress characterization in the different zones of the part were investigated. The density was determined by the Archimedes method, and the density measurement was divided into three regions, namely, the bottom, middle and top zones. The results show that the middle zone has a much smoother melting surface and that a relative density of nearly 100 % was achieved for the part in this study. The hardness profiles at room temperature, along the width and height directions of the cross-section of the top and bottom zones, were also studied. The residual stress was evaluated by X-ray diffraction (XRD) for the 316L SS specimen fabricated by the ASHM process, and it was compared with a specimen manufactured by the additive laser directed energy deposition (DED) process. The results show that the top and bottom zones exhibit tensile stress, and compressive stress occurs in the middle area. Moreover, the residual stress of ASHM shows a slightly smaller trend than that of the simplex DED due to the stress relaxation of the subsequent subtractive milling. These results may offer guidance for ASHM-fabricated 316L parts.
