Anoikis (or cell-detachment-induced apoptosis) is aspecial form of apoptosis in which cells loose contact with othercells or the extracellular matrix. In the present study, we havefound that the breast cancer stem cell line MCF-7-SC, isolatedfrom MCF-7 breast cancer cells, shows characteristics of anoikisresistance. Treatment of supercritical CO2 extract from Citrushassaku Hort ex Tanaka, locally known as Phalsak, reduced theexpression of ATP-binding cassette sub-family G member 2mRNA and induced apoptosis in MCF-7-SCs, as evidenced by anincrease of apoptotic body formation, increased cell population inthe sub-G1 phase, increase in the Bax/Bcl-2 ratio, proteolyticactivation of caspase-9 and caspase-3, and the degradation ofpoly(ADP-ribose) polymerase (PARP) protein. The effects ofsupercritical CO2 extract from Phalsak on anoikis-resistant breastcancer stem cells suggest the use of this extract as a potentialtherapeutic agent for breast cancer stem cell treatment.

This study will help researchers, developers, and managers to understand the major determinants of customer acceptance of mobile banking that can help banks to improve the rate of mobile banking adoption in developing country context. This study seeks to investigate the underlying factors of mobile banking in Vietnam and Korea. Thus, this study tries to analyze the underlying factors of the adoption of m-banking and the differences between developed country (Korea) and developing country (Vietnam) in terms of the adoption factors of mobile banking. The results indicated that environmental responsibility affect behavioral intention stronger than social responsibility. Therefore, Vietnamese companies as well as banks should incorporate CSR initiatives in their integrated marketing communication strategy in particular branding strategy to attract more customers. The results of the hypotheses testing showed the differences between Vietnam and South Korea and technology infrastructure difference between the two countries were the driving forces behind these different results. Managerial implications and the limitations of the study were also discussed.

Four rumen fistulated swamp buffaloes were randomly assigned according to a $4{\times}4$ Latin square design to investigate the effects of Eucalyptus (E. Camaldulensis) leaf meal (ELM) supplementation as a rumen enhancer on feed intake and rumen fermentation characteristics. The dietary treatments were as follows: T1 = 0 g ELM/hd/d; T2 = 40 g ELM/hd/d; T3 = 80 g ELM/hd/d; T4 = 120 g ELM/hd/d, respectively. Experimental animals were kept in individual pens and concentrate was offered at 0.3% BW while rice straw was fed ad libitum. The results revealed that voluntary feed intake and digestion coefficients of nutrients were similar among treatments. Ruminal pH, temperature and blood urea nitrogen concentrations were not affected by ELM supplementation; however, ELM supplementation resulted in lower concentration of ruminal ammonia nitrogen. Total volatile fatty acids, propionate concentration increased with the increasing level of EML (p<0.05) while the proportion of acetate was decreased (p<0.05). Methane production was linearly decreased (p<0.05) with the increasing level of ELM supplementation. Protozoa count and proteolytic bacteria population were reduced (p<0.05) while fungal zoospores and total viable bacteria, amylolytic, cellulolytic bacteria were unchanged. In addition, nitrogen utilization and microbial protein synthesis tended to increase by the dietary treatments. Based on the present findings, it is suggested that ELM could modify the rumen fermentation and is potentially used as a rumen enhancer in methane mitigation and rumen fermentation efficiency.

A series of experiments was conducted to investigate whether temperatures of 18 °C, 25 °C, 30 °C, and 35 °C and a photoperiod of 16L:8D at immature and adult stages would differentially affect the mating duration and egg production of Neoseiulus californicus females mated once. Mating duration was strictly determined by ambient temperature at the time of mating, regardless of the temperatures under which they were raised. Compared with a consistent 25 °C condition, total fecundity of females decreased when temperature conditions of 18 °C, 30 °C, and 35 °C were applied during any life stage (immature, mating, and oviposition periods) or a combination of different stages. In general, however, if mites were raised in conditions of ≤25 °C, and mated and oviposited at conditions of ≥25 °C, total egg production was relatively high. Based on these results, the adaptation of mites to thermal environments was discussed.

<P>We propose an efficient bioimaging strategy using Yb3+,Er3+,Eu3+-triplet doped YVO4 nanoparticles which were synthesized with polymer as a template. The obtained particles possess nanoscale, uniform, and flexible excitation. The effect of Eu3+ ions on the luminescence properties of YVO4:Yb3+,Er3+,Eu3+ was investigated. The upconversion mechanism of the prepared material was also discussed. The structure and optical properties of the prepared material were characterized by using X-ray diffraction (XRD), Fourier-transform IR spectroscopy (MR), scanning electron microscopy (SEM), Transmission electron microscopy (TEM) upconversion and photoluminescence spectra. The Commission International de I'Eclairage (CIE) chromaticity coordinates was investigated to confirm the performance of color luminescent emission. The prepared YVO4:Yb3+,Er3+,Eu3+ nanoparticles could be easily dispersed in water by surface modification with cysteine (Cys) and glutathione (GSH). The aqueous dispersion of the modified YVO4:Yb3+,Er3+,Eu3+ exhibits bright upconversion and downconversion luminescence and has been applied for bioimaging of HeLa cells. Our developed material with dual excitation offers a promising advance in bioimaging. (C) 2017 Elsevier B.V. All rights reserved.</P>

The purpose of this research is to investigate the mediating role of performance information use in the relationship between result-oriented culture and organizational performance. The data were collected from chief accountants and managers working in public-sector organizations in Vietnam. The analysis was based on the 197 completed questionnaires by using Partial Least Squares Structural Equation Modeling (PLSSEM). For the test research model and hypotheses, the supporting tool is SmartPLS 3 software. Research findings show that result-oriented culture is positively associated with organizational performance, and that performance information use is a mediating mechanism that explains how a result-oriented culture leads to higher performance in public organizations. The findings of this study suggest that the resultsoriented culture, not only directly improves organizational performance, but also indirectly does so by the use of performance information. This study provides evidence for theoretical understanding of the impact of result-oriented culture on the performance of public-sector organizations through performance information use, and suggests practical implications for public organizations in applying result-oriented culture to foster using performance measurement and improve organizational performance. In order to achieve good performance, publicsector organizations need to create and spread result-oriented culture and enhance the use of performance information for decision-making.
State Ownership and Firm Innovation? Evidence from an Emerging Market

The Vietnamese government has long recognized the essential importance of innovation in fostering sustainable competitive advantage and economic growth. While transitional countries have experienced limited research on SOEs and firm innovation, our research makes an initial effort to examine the impact of state ownership on innovation in Vietnam's emerging market using extensive panel data of firms listed on the Ho Chi Minh Stock Exchange from 2007 to 2016. The study integrates the institutional view, which regards that SOEs’ political and financial favoritism would connect firms to overcome constraints; and agency theory, which holds that SOEs would be less efficient in leveraging these critical resources in pursuing innovative projects. Our study demonstrates that innovation practices occur less often with the increased government involvement in a corporate structure. Our findings are attributable to the inherent problems of state-owned firms and suggest implications for managers and policymakers regarding the benefits and costs of state ownership in fostering innovation in the context of the socialist-oriented market economy of Vietnam.
