The red ginseng is known to have effects on antioxidativity and cytotoxicity. Nanoscale active substances have various advantages such as improved bioavailability and permeation ability into the cell. However, few studies conducted with the nanoparticles of red ginseng due to its low yield rate and difficulty of manufacturing the product in pilot scale. This study, therefore, investigated the size effects of ultra-fine powder of red ginseng on antioxidativity and cytotoxicity. Red ginseng powder (6, 8, or 158 μm) prepared using a pilot scale was provided by a local company. Antioxidativity was measured by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assays, and cytotoxicity was tested by methylthiazolyl tetrazolium (MTT) assay. The results of DPPH and ABTS radical electron donating ability IC50 of red ginseng were ranged from 2.27 to 3.34 mg/ml and 2.94 to 3.09 mg/ml, respectively, which were not significantly different between all samples. However, the results of cytotoxicity clearly showed a pattern of decreased toxicity in 6 and 8 μm power compared to 158 μm powder. Unexpectedly, particle sizes of red ginseng did not significantly affect antioxidativity. It is believed that these were related to the process of pilot scale production. These phenomena are also believed to be caused by aggregation of low size power particle that increases water holding capacity. From our result, it is concluded that this range of particle size of red ginseng affected the reduction of cytotoxicity.

The sweetpotato whitefly Bemisia tabaci (Gennadius) is a serious pest and vector of various virus causing economic losses in a variety of vegetables in Bangladesh as well as worldwide. In the present study, the mtCOI sequence of B. tabaci was analysed using 70 samples collected from different host plants at 12 districts of Bangladesh. Phylogenetic analysis was shown genetic divergence of our samples was 0.12 – 13.97%. There was three independent clusters such as Asia I, Asia II-1 and Asia II-5 genetic groups. Sequence diversity among three groups was 13.97%, 15.07% and 9.67%. Geographic diversity, for example, Asia I distributed in Central and Northern parts, Asia II-5 Central and Southern parts but Asia II-1 were present everywhere in Bangladesh. There was no B and Q aggressive biotypes in Bangladesh. Most Asia I and II was distributed in southeastern countries including Thailand, Vietnam, Pakistan, China and India. Our results provide understanding of genetic diversity of B. tabaci in southeast area.

United States litigation against China in the WTO will be ground zero for the new Trump administration’s aggressive trade policy. Five important facts must be highlighted to better understand the likely actions of the Trump administration. First, heightened judicial advocacy within the WTO will be consistent with both the Bush and Obama administrations’ aggressive use of the WTO’s dispute settlement system. Second, international judicial activism is squarely within the context of unfolding historical changes in international relations. Third, China hawks in the Trump administration will be competing with a number of countervailing forces in the White House, throughout the administration, and in the federal courts. Fourth, the US Congress has the exclusive authority to regulate global trade. However, much of this exclusive authority has been delegated to the president. Fifth, Trump considers trade as a zero-sum transaction, with a focus on the bottom line, to the exclusion of all else.

This study investigated the changes in appetite and behavior of cattle and pigs after foot-and-mouth disease (FMD) vaccination. This study involved ten calves and ten pigs, each divided into two groups of five animals. One group of each animal was vaccinated with an FMD vaccine (FMD-V), and the other group was used as a non-treated control (CON). Each animal’s appetite and behavior were observed before vaccination and for seven days post-vaccination. In the FMD-V groups, appetite and behavior scores during the seven days post-vaccination were significantly decreased compared to those in the CON groups. The only exception was the seventh day post-vaccination in the swine behavior scores.

The coronavirus porcine epidemic diarrhea virus (PEDV) infects the cells lining the small intestine of a pig and, causes porcine epidemic diarrhea (PED). Owing to its highly infectious nature, PEDV has a substantial economic burden, which results in significant morbidity and mortality in piglets. In this study, the virucidal efficacy of a powder disinfectant containing a phosphate compound against PEDV was investigated. Virucidal efficacy was assessed as the infectivity of PEDV toward Vero cells after exposure of the virus to the disinfectant. PEDV was exposed to the disinfectant in the presence of either hard water (HW) or an organic matter suspension (OM). In the HW condition, PEDV was inactivated by 4-fold dilution of the disinfectant. In the presence of OM, the disinfectant showed virucidal activity with a 2-fold dilution. As the disinfectant possessed virucidal activity against PEDV, it should be an effective reagent for limiting the spread of animal viral diseases.

Bisphenol‒A (BPA) is a known endocrine‒disrupting chemical used extensively to manufacture plastic bottles, canned food linings, thermal receipts, and other commonly used items. BPA is capable of inducing chromosomal alterations in germ cell line, thereby produced transgenerational effects on brain function, social recognition, reproductive diseases, sperm quality, gene expression, and obesity. Here, we aimed to investigate the transgenerational effects of BPA on murine male fertility. Six-week-old male mice (F0) were gavaged with corn oil (control), two different doses of BPA (5 mg, and 50 mg·kg bw-1·day-1),andethinylestradiol(EE,0.4mg·kg bw-1·day-1), dailyfor6weeks. Treated male mice were mated with wild‒type female and sibling pairs were bred up to the third generation (F3) in a similar manner with no further BPA exposure. Testes and spermatozoa were collected from 14-week-old males of all generation (F0 to F3) to evaluate testis weight, sperm function, and fertility. We found that high concentration of BPA significantly increased testicular weight in F2. Although the sperm viability, capacitation status, and intracellular ROS levels were not affected by BPA, however, sperm count, motility, hyperactivated motility, and intracellular ATP levels were significantly altered by BPA, dose dependently. In majority of the cases the effects were prominent in F2 followed by F1 and F0, whereas the effects were diminished in F3 generation. Simultaneously, high concentration of BPA significantly decreased cleavage and blastocyst formation rate in both F1 and F2. Similar inhibitory effects on cleavage and blastocyst were also noted in F1 by low dose of BPA. Depending on these findings we conclude that BPA decreases the fertility potential of exposed males and has an adverse impact on sperm function and fertility in subsequent generations.

Processes of cryopreservation consists of three steps: dilution with the extender/cooling (Step 1), addition of cryoprotectant (Step 2), and freezing/thawing (Step 3) and spermatozoa are exposed different kind of environment and stress in each step. We categorized sperm samples as good freezablitiy (GF), damaged by cryoprotectant (DCP), and damaged by freezing (DF) and identified characteristics of each group in different step of cryopreservation. In Step 2, DCP was significantly decreased in motility, rapid speed and increased in slow speed. DF was significantly decreased in only motility whereas there were no significant difference between GF and DF and significantly higher than DCP in Step 2. Motility, rapid, medium speed of all group were significantly decreased in Step 3 and GF was significantly higer than other groups. AR pattern of all groups were significantly increased in Step 3 whereas GF was significantly lower than other groups. Additionally AR pattern of DF was significantly increased in Step 2. F pattern of DF and DCP were significantly decreased in Step 3. There no difference of B pattern in whole process. Mitochondrial activity of DCP was significantly decreased in Step 2 and mtichondrial activity of all groups were significantly decreased in Step 3. However mtichondrial activity of GF was higher than other groups. Viability result shows same significant difference with mitochondrial pattern. The present study compared with various sperm parameters in different groups which has different freezability. We defined different two types of group that damaged from different step of cryopreservation. DF and DCP is mainly damaged in Step 3 and Step 2 respectively. The results of current study suggest that various sperm parameters can be used as physical markers in freezability.

The sweetpotato whitefly Bemisia tabaci (Gennadius) is one of the most important sap sucking pests causing economic losses in a variety of vegetables in Bangladesh and as well as around the world. In the present study, the mtCOI sequence of B. tabaci was analysed using samples collected from different host plants (Potato, Brinjal, Tomato, Sweet potato, Bean) from district Gazipur, Patuakhali, Rajshahi and Nilphamari of Bangladesh. Phylogenetic analysis of our samples and relative sequences of B. tabaci in NCBI database was shown three independent clusters. Samples in Bangladesh were most similar with those of Thailand, Vietnam, Pakistan, China and India but did not show any B and Q aggressive biotypes.

Even though Memetics, the study area of meme maps, has been well-studied in the Cognitive Neuroscience and Computer Science disciplines, there has been no research attempt on Memetics in the Tourism and Hospitality field. Seminal studies in the marketing field suggest that the concepts of destination image and meme maps are highly-related. Accordingly, the purpose of the current study is twofold: (1) to identify the overall Destination Image Meme Maps of Antalya, Turkey and their favorite tourism destination, and (2) to identify and evaluate the similarities and differences in the structures of the previously generated two categories of Destination Image Meme Maps. The data was gathered from two samples consisting of 272 Russian and 262 German travelers visiting a medium-sized city (i.e. Antalya) located in the south region of Turkey. This study adopts and enhances the knowledge of Memetics into Tourism and Hospitality research. It also provides important practical and methodological contributions.

In recent years, leading digital technology companies have shown a strong interest in enabling children to send electronic word of mouth (eWOM). Recasting children from passive to active participants in marketing communications, this shift expands children’s marketing practices from how a company influences children via traditional marketing communications to how children influence a company’s marketing practices through eWOM. This paper aims to enhance our understanding about the use of children’s eWOM in marketing communications when children’s eWOM and children’s marketing begin to intersect. The eWOM literature demonstrated the effects of eWOM on product sales without identifying the sender (King, Racherla, & Bush, 2014). The extension of the effects from aggregated sender to children needs careful study in light of children’s marketing literature which showed children have distinct characteristics in the context of traditional marketing (Cross, 2002). In this study, we examine the positive expectation of business impact that explains firms’ adoption of children’s eWOM and further investigate the normative concerns about the social influence of children’s eWOM.

This study examines consumers’ online activities according to the categories of goods and services, applying foraging theory, and explore online information structure perceived by consumers, determining the degree of information overload. Consumers are confronted by nearly unlimited amounts of information when they gather information to make purchase decisions in an online environment. Few studies have focused on the behavioral pattern of information acquisition to reduce information overload. The available studies are limited by particular conditions under a normative perspective (e.g., cognitive limitation with item specific information only and overemphasis on the quantity dimension of information structure). An improvement may be a holistic approach that allows freedom of information acquisition, and includes an ecological perspective, which emphasizes an interaction between minds and immediate environments (Todd & Gigerenzer, 2007). In other words, to provide a better explanation of information overload phenomenon, the research includes quantity information as well as quality and environmental information in the information structure. This has been overlooked in an information overload paradigm (for example, the question of whether more or less information is better) (Scheibehenne, Greifeneder, & Todd, 2010). Moreover, Xia and Monroe (2005) argued that the majority of research about information acquisition has overemphasized information searching while overlooking information browsing, although both activities occur concurrently during processes of information acquisition. The foraging theory (Stephen and Kreb, 1986), which originated from behavioral ecology, can help explain a continuum of browsing and searching behavior through utilizing the patch framework (Kim & Hantula, 2016). The patch framework provides a different perspective for information structure in terms of the amount of data as a combination of within-patch (searching) and between-patch (browsing), thereby covering the issue of the browse-search continuum to explain issues of amount for information overload. (e.g., Detlor, Sproule, & Gupta, 2003). The current study applied foraging theory into the online behavior of information acquisition and explored the information structure that consumers establish and consider in their process of information foraging across categories of goods and services (i.e., durables, nondurables, and services). This theoretical integration would proffer some clues for information structure to reduce information overloads through browsing and searching information online. The investigations consist of ordinary activities and purchase-related activities online, frequently purchased items and consideration to make purchase decisions, strategic information foraging patterns, and perceived decisional difficulty.
