Jie Wang,Yuan Su,Mauricio A. Elzo,Xian-Bo Jia,Shi-Yi Chen,Song-Jia Lai 한국축산식품학회 2016 한국축산식품학회지 Vol.36 No.1

The objective of this study was to compare carcass composition and meat quality traits in the longissimus dorsi and biceps femoris muscles in the Hyla, Champagne and Tianfu Black rabbit breeds. Tianfu Black rabbits had the heaviest head, skin, thoracic viscera and commercial carcass percentage (p<0.05). In addition, Tianfu Black had the highest pH0 h value, followed by the Champagne and Hyla breeds (p<0.01) in the longissimus dorsi and biceps femoris muscles. Tianfu Black had a higher a* (0 h and 24 h) than the other two breeds in both longissimus dorsi and biceps femoris muscles (p<0.05). The Hyla, Champagne, and Tianfu Black breeds showed a similar pattern of differences for meat quality traits (pH, L*, a* and b*) measured in fresh meat (0 h) and meat stored for 24 h. Hyla had the highest IMF values of the three breeds (p<0.01). The lower intramuscular fat of Tianfu Black and Champagne rabbits gives them an advantage over Hyla rabbits among most consumers seeking lean rabbit meat.

Jie-Peng Jia,Quan Shao,Ying-Kai Wang,Bo Qian,Wen Zhang,Tao Hu,Ji-Jun Zhang 한국고분자학회 2021 Macromolecular Research Vol.29 No.11

With the reaction between bib ligands, 5-substituted isophthalic acid and Cd(II) ions, we produced two coordination polymers in success, that is, [Cd(5-meo-ip) (bib)0.5]n (2) and [Cd(5-me-ip)(bib)(H2O)]n·n(H2O) (1) (bib is 1,4-bis(imidazoly)butane, 5-meo-H2ip is 5-methoxyisophthalic acid, and 5-me-H2ip is 5-methylisophthalic acid). The luminescent performances and thermal stability of the two compounds were also explored. Their anti-pancreatic cancer activity combined with biliary stent placement and 125I particles was evaluated and the specific mechanism was explored as well. Firstly, after the model construction and compound treatment, the weight and volume of the tumor tissue was measured. Next, the apoptosis level of the cancer cells were evaluated with Annexin V-FITC/PI apoptosis assay.

Jie Jia,Xiaobo Feng,Weihua Xu,Shu-Hua Yang,Qing Zhang,Xianzhe Liu,Yong Feng,Zhipeng Dai 생화학분자생물학회 2014 Experimental and molecular medicine Vol.46 No.-

MicroRNAs (miRNAs) have recently been recognized to have a role in human orthopedic disorders. The objective of our study was to explore the expression profile and biological function of miRNA-17-5p (miR-17-5p), which is well known to be related to cancer cell proliferation and invasion, in osteoblastic differentiation and in cell proliferation. The expression levels of miR-17- 5p in the femoral head mesenchymal stem cells of 20 patients with non-traumatic osteonecrosis (ON) and 10 patients with osteoarthritis (OA) were examined by quantitative reverse transcription-PCR (qRT–PCR). Furthermore, the interaction between miR-17-5p and SMAD7 was observed. We found that in non-traumatic ON samples the level of mature miR-17-5p wassignificantly lower than that of OA samples (P¼0.0002). By targeting SMAD7, miR-17-5p promoted nuclear translocation of b-catenin, enhanced expression of COL1A1 and finally facilitated the proliferation and differentiation of HMSC-bm cells. We also demonstrated that restoring expression of SMAD7 in HMSC-bm cells partially reversed the function of miR-17-5p. Together, our data suggested a theory that dysfunction of a network containing miR-17-5p, SMAD7 and b-catenin could contribute to ON pathogenesis. The present study prompts the potential clinical value of miR-17-5p in non-traumatic ON.

Switching Picture Added Scalable Video Coding and its Application for Video Streaming Adaptive to Dynamic Network Bandwidth

Jia, Jie,Choi, Hae-Chul,Kim, Hae-Kwang The Korean Institute of Broadcast and Media Engine 2008 방송공학회논문지 Vol.13 No.1

Transmission of video over Internet or wireless network requires coded stream capable of adapting to dynamic network conditions instantly. To meet this requirement, various scalable video coding schemes have been developed, among which the Scalable Video Coding (SVC) extension of the H.264/AVC is the most recent one. In comparison with the scalable profiles of previous video coding standards, the SVC achieves significant improvement on coding efficiency performance. For adapting to dynamic network bandwidth, the SVC employs inter-layer switching between different temporal, spatial or/and fidelity layers, which is currently supported with instantaneous decoding refresh (IDR) access unit. However, for real-time adaptability, the SVC has to frequently employ the IDR picture, which dramatically decreases the coding efficiency. Therefore, an extension of SP picture from the AVC to the SVC for an efficient inter-layer switching is investigated and presented in this paper. Simulations regarding the adaptability to dynamic network bandwidth are implemented. Results of experiment show that the SP picture added SVC provides an average 1.2 dB PSNR enhancement over the current SVC while providing similar adaptive functionality.

Interactive Effect of Bisphenol A (BPA) Exposure with -22G/C Polymorphism in LOX Gene on the Risk of Osteosarcoma

Jia, Jie,Tian, Qing,Liu, Yong,Shao, Zeng-Wu,Yang, Shu-Hua Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

Background: Osteosarcomas have many established risk factors, both genetic and environmental, but by themselves these explain only part of the total cancer incidence. Bisphenol A (BPA) is an environmental estrogen associated with risk of several kinds of tumour. The lysyl oxidase gene (LOX) may also contribute to risk of tumours including osteosarcomas. Here, we investigated possible interactions of BPA and a LOX polymorphism on the risk of osteosarcoma. Method: The present hospital-based case-control study included 106 cancer patients and 112 controls from a Chinese population. Internal burden of BPA exposure was assessed using high-performance liquid chromatography-mass spectrometry (HPLC-MS) method. Genotypes were determined using PCR-RFLP methods. Results: Compared with those in low BPA exposure group, subjects with BPA more than or equal to median value had significant increased risk of osteosarcoma among subjects who carried GC or CC genotypes. A significant interaction with BPA level and the -22G/C polymorphism was observed for osteosarcoma overall, osteosarcoma affecting knee and osteosarcoma affecting hip, as $P_{forinteraction}$ = 0.036 for osteosarcoma overall; $P_{forinteraction}$ = 0.024 for osteosarcoma affecting knee; and $P_{forinteraction}$ = 0.017 for osteosarcoma affecting hip. Conclusions: The results suggest that BPA exposure interacts with the -22G/C polymorphism of the LOX gene to increase the risk of osteosarcoma.

Jie Jia,Qiusi Lin,Jian Chen,Xingwei Wang 한국전자통신연구원 2013 ETRI Journal Vol.35 No.3

Due to limited spectrum resources and differences in link loads, network congestion is one of the key issues in cognitive radio wireless mesh networks. In this letter, a congestion avoidance model with power control, channel allocation, and routing under the signal-to-interference-and-noise ratio is presented. As a contribution, a nested optimization scheme combined with a genetic algorithm and linear programming solver is proposed. Extensive simulation results are presented to demonstrate the effectiveness of our algorithm.

A Predictive Block Based DC Offset for H.264/AVC Video Coding

JIA, Jie,YOON, Daeil,KIM, Hae Kwang The Institute of Electronics, Information and Comm 2010 IEICE transactions on fundamentals of electronics, Vol.93 No.5

<P>Video coding standard H.264/AVC employs transform coding to explore spatial correlation in inter picture prediction residue. This paper presents a block based DC offset to further explore the correlation in spatially neighboring blocks and provides H.264/AVC an enhanced coding efficiency performance. The proposed method applies DC offset to inter picture prediction residue, and encodes the offset compensated residual signal. The DC offset is derived from reconstructed residue in neighboring blocks. No additional bits are required for the DC offset representation. Simulation results report that the proposed method yields an average of 2.67% bit rate reduction for high resolution video over the H.264 baseline profile.</P>

An Improved Run_before Coding for H.264 CAVLC

JIA, Jie,YOON, Daeil,KIM, Hae Kwang The Institute of Electronics, Information and Comm 2010 IEICE transactions on fundamentals of electronics, Vol.93 No.2

<P>Context-based adaptive variable length coding (CAVLC) is an entropy coding scheme employed in H.264/AVC for transform coefficient compression. The CAVLC encodes levels of nonzero-valued coefficients. Then indicates their positions with run_before which is number of zeros preceding each nonzero coefficient in scan order. In H.264, the run_before is coded using lookup tables depending on number of zero-valued coefficients that have not been coded. This paper presents an improved run_before coding method which encodes run_before using tables taking both zero-valued and nonzero-valued coefficients into consideration. Simulation results report that the proposed method yields an average of 4.40% bit rate reduction for run_before coding over H.264 baseline profile with intra-only coding structure. It corresponds to 0.52% bit rate saving over total bit rate on average.</P>

Jia-Chen Yang,Jia-Yu Chen,Yin Ding,Yong-Jie Yin,Zhi-Ping Huang,Xiu-Hua Wu,Zu-Cheng Huang,Yi-Kai Li,Qing-An Zhu 대한척추신경외과학회 2024 Neurospine Vol.21 No.1

Objective: The effect on fat infiltration (FI) of paraspinal muscles in degenerative lumbar spinal diseases has been demonstrated except for spinopelvic parameters. The present study is to identify the effect of spinopelvic parameters on FI of paraspinal muscle (PSM) and psoas major muscle (PMM) in patients with degenerative lumbar spondylolisthesis. Methods: A single-center, retrospective cross-sectional study of 160 patients with degenerative lumbar spondylolisthesis (DLS) and lumbar stenosis (LSS) who had lateral full-spine x-ray and lumbar spine magnetic resonance imaging was conducted. PSM and PMM FIs were defined as the ratio of fat to its muscle cross-sectional area. The FIs were compared among patients with different pelvic tilt (PT) and pelvic incidence (PI), respectively. Results: The PSM FI correlated significantly with pelvic parameters in DLS patients, but not in LSS patients. The PSM FI in pelvic retroversion (PT > 25°) was 0.54 ± 0.13, which was significantly higher in DLS patients than in normal pelvis (0.41 ± 0.14) and pelvic anteversion (PT < 5°) (0.34 ± 0.12). The PSM FI of DLS patients with large PI ( > 60°) was 0.50 ± 0.13, which was higher than those with small ( < 45°) and normal PI (0.37 ± 0.11 and 0.36 ± 0.13). However, the PSM FI of LSS patients didn’t change significantly with PT or PI. Moreover, the PMM FI was about 0.10–0.15, which was significantly lower than the PSM FI, and changed with PT and PI in a similar way of PSM FI with much less in magnitude. Conclusion: FI of the PSMs increased with greater pelvic retroversion or larger pelvic incidence in DLS patients, but not in LSS patients.
