Hong Hong ZHU,Yue Yao SUN,Jin Bao LI 한국유통과학회 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.3

The iron and steel sector is caught between two worlds: “carbon reduction” and “development.” The goal of this study is to show that optimizing asset structure to boost intangible assets, particularly brand assets, is a viable strategy to achieve low-carbon development. This study uses panel data from 38 A-share companies in China’s iron and steel industry from 2010 to 2020, as well as World Brand Lab data, to create a comprehensive impact index of enterprise value from the standpoint of an asset structure optimization, and to test the impact of intangible assets and brand equity on enterprise value. The findings show that: the asset structure of iron and steel enterprises is closely related to enterprise value, implying that iron and steel industry development necessitates a transformation of quantity control and quality improvement; the proportion of intangible assets in the asset structure of iron and steel enterprises plays a positive and critical role in enterprise value under surplus conditions. The iron and steel industry begins to shift from tangible to intangible assets; there is heterogeneity in the iron and steel industry transformation. Given certain technological levels, the share of brand assets contributes significantly to the increase in enterprise value.

Electrical properties of Mg x Zn1−x O thin films deposited by using RF magnetron co-sputtering with ZnO and Mg0.3Zn0.7O targets

Yue, Li Li,Yang, Yi Da,Kim, Hong Seung,Jang, Nak Won,Yun, Young 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol. No.

<P>We successfully deposited hexagonal wurtzite Mg (x) Zn1-x O (0 a parts per thousand currency sign x a parts per thousand currency sign 0.18) films on Si substrates by using RF magnetron co-sputtering with ZnO and Mg0.3Zn0.7O targets. The Mg content was varied by controlling the RF power of the Mg0.3Zn0.7O target while the RF power of the ZnO target was fixed at 100 W. The electrical properties of the Mg (x) Zn1-x O films were investigated by using a transmission line model (TLM) with Ti/Au electrode and Hall effect measurements. The X-ray diffraction (XRD) results demonstrate that some Zn atoms can be replaced by Mg atoms in the Mg (x) Zn1-x O films. As the Mg content was increased from 0 at.% to 18 at.%, the resistivity of Mg (x) Zn1-x O films increased and the carrier concentration decreased from 1.17 x 10(19) cm(-3) to 1.17 x 10(17) cm(-3), which indicates a decrease in the number of oxygen vacancies. Meanwhile, the Hall mobility increased to 15.3 cm(2)/Vs. The electrical properties of Mg (x) Zn1-x O films were tuned by using the Mg content.</P>

Li, Li-Ping,Cheng, Wei-Bo,Li, Hong,Li, Wen,Yang, Hui,Wen, Ding-Hou,Tang, Yue-Di Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.6

The functional significance of the proteasome activator $REG{\gamma}$ in the regulation of cell proliferation and apoptosis has been recognized. However, pathological contributions to tumor development remain to be elucidated. Both oncogenic proteins and tumor suppressors are targeted by $REG{\gamma}$ for proteasomal degradation. It has been proposed that the role of the $REG{\gamma}$ in the pathogenesis of cancer is cell- and context-specific. In this study, we aimed to explore the potential involvement of $REG{\gamma}$ in laryngeal carcinomas, comparing protein expression in tumor and adjacent tissues by immunohistochemical staining and Western blot analysis. We also characterized the correlation between the expression of $REG{\gamma}$ and the previously identified substrates p53 and p21. We showed that $REG{\gamma}$ was abnormally highly expressed in cancer tissues. Statistical analysis revealed that there was a positive relationship between the level of $REG{\gamma}$ and the expression of p53 and p21. Our study suggests that $REG{\gamma}$ overexpression can facilitate the growth of laryngeal cancer cells.

Yue, Hong Yan,Huang, Shuo,Chang, Jian,Heo, Chaejeong,Yao, Fei,Adhikari, Subash,Gunes, Fethullah,Liu, Li Chun,Lee, Tae Hoon,Oh, Eung Seok,Li, Bing,Zhang, Jian Jiao,Huy, Ta Quang,Luan, Nguyen Van,Lee, Y American Chemical Society 2014 ACS NANO Vol.8 No.2

<P>We report that vertically aligned ZnO nanowire arrays (ZnO NWAs) were fabricated on 3D graphene foam (GF) and used to selectively detect uric acid (UA), dopamine (DA), and ascorbic acid (AA) by a differential pulse voltammetry method. The optimized ZnO NWA/GF electrode provided a high surface area and high selectivity with a detection limit of 1 nM for UA and DA. The high selectivity in the oxidation potential was explained by the gap difference between the lowest unoccupied and highest occupied molecular orbitals of a biomolecule for a set of given electrodes. This method was further used to detect UA levels in the serum of patients with Parkinson’s disease (PD). The UA level was 25% lower in PD patients than in healthy individuals. This finding strongly implies that UA can be used as a biomarker for PD.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2014/ancac3.2014.8.issue-2/nn405961p/production/images/medium/nn-2013-05961p_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn405961p'>ACS Electronic Supporting Info</A></P>

ER81-shRNA Inhibits Growth of Triple-negative Human Breast Cancer Cell Line MDA-MB-231 In Vivo and in Vitro

Chen, Yue,Zou, Hong,Yang, Li-Ying,Li, Yuan,Wang, Li,Hao, Yan,Yang, Ju-Lun Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.5

The lack of effective treatment targets for triple-negative breast cancers make them unfitted for endocrine or HER2 targeted therapy, and their prognosis is poor. Transcription factor ER81, a downstream gene of the HER2, is highly expressed in breast cancer lines, breast atypical hyperplasia and primary breast cancers including triple-negative examples. However, whether and how ER81 affects breast cancer carcinogenesis have remained elusive. We here assessed influence on a triple-negative cell line. ER81-shRNA was employed to silence ER81 expression in the MDA-MB-231 cell line, and MTT, colony-forming assays, and flow cytometry were used to detect cell proliferation, colony-forming capability, cell cycle distribution, and cell apoptosis in vitro. MDA-MB-231 cells stably transfected with ER81-shRNA were inoculated into nude mice, and growth inhibition of the cells was observed in vivo. We found that ER81 mRNA and protein expression in MDA-MB-231 cells was noticeably reduced by ER81-shRNA, and that cell proliferation and clonality were decreased significantly. ER81-shRNA further increased cell apoptosis and the residence time in $G_0/G_1$ phase, while delaying tumor-formation and growth rate in nude mice. It is concluded that ER81 may play an important role in the progression of breast cancer and may be a potentially valuable target for therapy, especially for triple negative breast cancer.

Objective: To evaluate the spontaneous brain activity alterations in liver transplantation (LT) recipients using resting-state functional MRI. Materials and Methods: Twenty cirrhotic patients as transplant candidates and 25 healthy controls (HCs) were included in this study. All patients repeated the MRI study one month after LT. Amplitude of low-frequency fluctuation (ALFF) values were compared between cirrhotic patients (both pre- and post-LT) and HCs as well as between the pre- and post-LT groups. The relationship between ALFF changes and venous blood ammonia levels and neuropsychological tests were investigated using Pearson’s correlation analysis. Results: In the cirrhotic patients, decreased ALFF in the vision-related regions (left lingual gyrus and calcarine), sensorimotor-related regions (left postcentral gyrus and middle cingulate cortex), and the default-mode network (bilateral precuneus and left inferior parietal lobule) were restored, and the increased ALFF in the temporal and frontal lobe improved in the early period after LT. The ALFF decreases persisted in the right supplementary motor area, inferior parietal lobule, and calcarine. The ALFF changes in the right precuneus were negatively correlated with changes in number connection test-A scores (r = 0.507, p < 0.05). Conclusion: LT improved spontaneous brain activity and the results for associated cognition tests. However, decreased ALFF in some areas persisted, and new-onset abnormal ALFF were possible, indicating that complete cognitive function recovery may need more time.

Evaluating the electric property of different crystal faces and enhancing the Raman scattering of Cu2O microcrystal by depositing Ag on the surface

Hong Gao,Junying Zhang,Min Li,Kejia Liu,Dong Guo,Yue Zhang 한국물리학회 2013 Current Applied Physics Vol.13 No.5

The surface electric property of Cu2O microcrystal affects the interaction of facets with substance in the aqueous solution, and hence plays a key role in determining the photocatalytic activity. In this paper, the capability of Cu2O microcrystals with exclusive {111}, {110} or both lattice surfaces in reducing Agþ to Ag0were investigated. Ag particles selectively deposited on {111} surfaces of Cu2O, while not on {110} surfaces. The different behaviors of the two surfaces are mainly attributed to their different electric properties:negatively-charged {111} surfaces absorb Agþ ions while positively-charged {110} surfaces repel them. Raman scattering of Cu2O {111} surfaces was enhanced by the photo-deposition of Ag particles.

( Hong-xu Yang ),( Yue Shang ),( Quan Jin ),( Yan-ling Wu ),( Jian Liu ),( Chun-ying Qiao ),( Zi-ying Zhan ),( Huan Ye ),( Ji-xing Nan ),( Li-hua Lian ) 한국응용약물학회 2020 Biomolecules & Therapeutics(구 응용약물학회지) Vol.28 No.4

In current study, we aimed to investigate whether the gentiopicroside (GPS) derived from Gentiana manshurica Kitagawa could block the progression of alcoholic hepatic steatosis to fibrosis induced by chronic ethanol intake. C57BL/6 mice were fed an ethanol- containing Lieber-DeCarli diet for 4 weeks. LX-2 human hepatic stellate cells were treated with GPS 1 h prior to transforming growth factor-β (TGF-β) stimulation, and murine hepatocyte AML12 cells were pretreated by GPS 1 h prior to ethanol treatment. GPS inhibited the expression of type I collagen (collagen I), α-smooth muscle actin (α-SMA) and tissue inhibitor of metal protease 1 in ethanol-fed mouse livers with mild fibrosis. In addition, the imbalanced lipid metabolism induced by chronic ethanol-feeding was ameliorated by GPS pretreatment, characterized by the modulation of lipid accumulation. Consistently, GPS inhibited the expression of collagen I and α-SMA in LX-2 cells stimulated by TGF-β. Inhibition of lipid synthesis and promotion of oxidation by GPS were also confirmed in ethanol-treated AML12 cells. GPS could prevent hepatic steatosis advancing to the inception of a mild fibrosis caused by chronic alcohol exposure, suggesting GPS might be a promising therapy for targeting the early stage of alcoholic liver disease.

A Demand Response Energy Management Scheme for Industrial Facilities in Smart Grid

Yue Min Ding,Seung Ho Hong,Xiao Hui Li IEEE 2014 IEEE TRANSACTIONS ON INDUSTRIAL INFORMATICS - Vol.10 No.4

<P>Demand response (DR) smart grid technology provides an opportunity for electricity consumers to actively participate in the management of power systems. Industry is one of the major consumers of electric power. In this study, we propose a DR energy management scheme for industrial facilities based on the state task network (STN) and mixed integer linear programming (MILP). The scheme divides the processing tasks in industrial facilities into nonschedulable tasks (NSTs) and schedulable tasks (STs), and takes advantage of distributed energy resources (DERs) to implement DR. Based on day-ahead hourly electricity prices, the scheme determines the scheduling of STs and DERs in order to shift the demand from peak periods (with high electricity prices) to off-peak periods (with low electricity prices), which not only improves the reliability of the electric power system, but also reduces energy costs for industrial facilities.</P>
