Oyster mushrooms are popular and physiologically beneficial to human health. This study was conducted to investigate the effect of dietary supplementation of oyster mushrooms such as Pleurotus ostreatus, P. pulmonarius, and P. citrinopileatus on high cholesterol fed rats. Five-week old female Sprague-Dawley albino rats were divided into three groups of 8 rats each. Feeding a diet containing a 5% fruiting body powder of Pleurotus species to high cholesterol fed rats reduced plasma total cholesterol (TG), triglyceride (TG), low-density lipoprotein (LDL). Feeding each oyster mushroom also significantly reduced body weight in high cholesterol fed rats. However, it had no adverse effects on plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, total protein or enzyme profiles such as glutamate oxalate transaminase (GOT), glutamate pyruvate transaminase (GPT), and alkaline phosphatase (ALP) which are related to kidney function. Feeding each mushroom increased total lipid and cholesterol excretion in feces. A histological study of hepatic cells by conventional red O staining showed normal findings in mushroom-fed hyperlipidemic rats. These results suggested that diet supplementation of 5% fruiting body power of Pleurotus species provided health benefits by acting on the atherogenic lipid profile in high cholesterol fed rats.

Ochratoxin A, which is frequently detected in cereals and infant diets worldwidely, is a mycotoxin to damage mainly the kidney and liver. Because ochratoxin A is highly thermostable compound. it is necessary to study ways of reducing level of ochratoxin A by controling processing steps. However, food processes, including extrusion, expansion, roasting, and steam cooking, which are used in order to mitigate the contents of ochratoxin A, are known to produce polycyclic aromatic hydrocarbons, which are generated from radicals decomposed by pyrolysis. Therefore, this study analyzed the levels of 4 polycyclic aromatic hydrocarbons, benz (a) anthracene, chrysene, benzo (b) fluoranthene and benzo (a) pyrene in rice-based products made in high pressure and heating process. Rice samples were finely ground, and homogenized samples were alkaline treatement with 1 M KOH/EtOH and extracted with liquid-liquid extraction method using n-hexane. The extracted solution was pretreated with a silica cartridge. The purified solution was dried with nitrogen gas and dissolved in 1 mL of dichloromethane and injected into GC/MSD. We had overall recoveries for 4 polycyclic aromatic hydrocarbons spiked into rice samples ranging from 92.8 to 110.2%. The limit of quantitations of benz (a) anthracene, chrysene, benzo (b) fluoranthene and benzo (a) pyrene in rice-based product were 0.19 ng/g, 0.38 ng/g, 0.51 ng/g, and 0.31 ng/g, respectively. However, these 4 polycyclic aromatic hydrocarbons in all processed rice samples were not detected.

In order to perform the biological investigation of coffee extract containing different molecules, it would be necessary to develop in vitro experimental system rather than animal experiment. Although the animal experiment treated via oral intake or intravenous injection may disclose the whole systemic effect, the in vitro cell culture experiment would be more convenient to analyze direct cellular effect of coffee extract than animal experiment. Therefore, this study was aimed to develop a dialysis method for the crude coffee extract to perform the biological investigation using murine macrophage cell line, RAW 264.7. First of all, the RAW 264.7 cells treated with dialyzed coffee extract were observed, and subsequently their protein extracts were analyzed by gel filtration chromatography, thin layer chromatography, and immunoprecipitation high performance liquid chromatography (IP-HPLC). Resultantly, it was found that the low dose (20μg/mL) of dialyzed coffee extract, about 5 cups of ordinary coffee drinking for human adult, enhanced the growth of RAW 264.7 cells by increased expression of β-actin and Ki-67, and also induced the anti-inflammatory effect by decreased expression of NFkB, TNFα, and LC3 contrast to the high dose (40μg/mL) of dialyzed coffee extract. The low dose of dialyzed coffee extract produced almost no harmful effect on RAW cell culture for 12 hours, rather than it produced stimulatory effect on RAW cells by increasing the cell number and enhancing the protein expression of β-actin, Ki-67. Therefore, it was thought that the low dose of dialyzed coffee extract is applicable to cell culture experiment without difficult purification procedures of coffee elements. In addition, as the contrast cellular effect between the low and high dose of coffee extract was found in this study, it was also presumed that the low dose of coffee extract may play an important role in the inflammatory reaction of murine macrophages.

Vinca alkaloids from plant Vinca minor have been investigated for their effects of tyrosinase inhibition, stimulation of ROS generation and increasement of cell migration activity. The methanolic crude extract and the water-soluble fraction exhibited IC50 value of 3.1 mg/mL and 2.1 mg/mL. Vinca minor extract treatment significantly increased ROS levels in HaCaT cells, in a concentration-dependent manner. Treatments of Vinca minor extract led to increase wound closure when compared with non-treatment. Low dose (0.1% or 0.3%) of extracts have not significantly affected, compared with that in controls. By contrast, 0.5% extract have dramatic effect on wound healing activity of keratinocytes. Effects of Vinca minor extract in a filter-based cell mobility assay appear similar to that of wound closure assay, which suggests that the Vinca minor extract have wound healing effects on skin.

This study aimed to reveal the designer’s creative process in the development of clothing designs. The researcher has taken roles both as a design practitioner and an observer. The full process of design development was concurrently documented while working to solve a specific problem. This included noting down the concept, keywords, and detailed scratch ideas, as well as refining the design by collecting sketches and taking photos. Integrated data from the captured design process were analyzed based on Lamb and Kallal’s apparel design framework, which included problem identification, construction of preliminary ideas, design refinement, prototype development, and evaluation. The functional, expressive, and aesthetic (FEA) criteria of the entire process were thus assessed. Additionally, five professional apparel reviewers evaluated the design project based on FEA criteria. The results showed the processes for identifying targets and intentions, extracting the main elements from sources, developing the major visual concepts, and making final adjustments. Ultimately, this study revealed how a designer manages each stage of the creative design process. Sharing such detailed observations of the design process can help refine the knowledge involved in each stage of the creative process, and provide guidance for instructors in design education.

We present analyses of 1250 variable sources identied in a 20 square degree eld toward NGC 2784 by the KMTNet Supernova Program. We categorize the variable sources into three groups based on their B-band variability. The rst group consists of 31 high variability sources with their B- band RMS variability greater than 0.3 magnitudes. The second group of medium variability contains 265 sources with RMS variability between 0.05 and 0.3 magnitudes. The remaining 951 sources belong to the third group of low variability with an RMS variability smaller than 0.05 magnitudes. Of the entire 1250 sources, 4 clearly show periods of variability greater than 100 days, while the rest have periods shorter than 51 days or no reliable periods. The majority of the sources show either rather irregular variability or short periods faster than 2 days. Most of the sources with reliable period determination between 2 and 51 days belong to the low-variability group, although a few belong to the medium-variability group. All the variable sources with periods longer than 35 days appear to be very red with B􀀀V > 1.5 and V 􀀀I > 2.1 magnitudes. We classify candidates of 51 Cepheids, 17 semi-regular variables, 3 Mira types, 2 RV(B) Tauri stars, 26 eclipsing binary systems and 1 active galactic nucleus. The majority of long-term variables in our sample belong to either Mira or semi-regular types, indicating that long-term variability may be more prominent in post-main sequence phases of late-type stars. The depth of the eclipsing dips of the 26 candidates for eclipsing binaries is equivalent to 0.61 as the average relative size of the two stars in the binary system. Our results illustrate the power of the KMTNet Supernova Program for future studies of variable objects.

Arsenic (As) is a toxic element that easily taken up by plants root. Several toxic forms of As disrupt plant metabolism by a series of cellular alterations. In this study, we applied annealing control primer (ACP)-based reverse transcriptase PCR (polymerase chain reaction) technique to identify differentially expressed genes (DEGs) in alfalfa roots in response to As stress. Two-week-old alfalfa seedlings were exposed to As treatment for 6 hours. DEGs were screened from As treated samples using the ACP-based technique. A total of six DEGs including heat shock protein, HSP 23, plastocyanin-like domain protein162, thioredoxin H-type 1 protein, protein MKS1, and NAD(P)H dehydrogenase B2 were identified in alfalfa roots under As stress. These genes have putative functions in abiotic stress homeostasis, antioxidant activity, and plant defense. These identified genes would be useful to increase As tolerance in alfalfa plants.

As the global cosmetics market becomes more competitive, cosmetics firms need to be more market-oriented. Consumers purchase cosmetics products not only based on product-related attributes (e.g., function) but also for non-product-related reasons such as novelty and a pursuit of variety. They are exposed and have access to a variety of choices imported from other countries, which further complicates decision-making. Globalization offers great opportunities for marketers as it may help expand the horizon of the market beyond the domestic boundary. Given that the market is becoming more competitive, it is imperative to understand what influences purchase decisions of global consumers. This study considers and examines extended susceptibility to global consumer culture (Extended SGCC) and its effect on affective commitment, which in turn influences behavioral commitment and loyalty. We consider four elements of extended SGCC: conformity to consumer trend, social prestige, quality perception, and corporate social responsibility. In addition to examining the structural relationships among the variables, we test whether country of origin (COO) moderates the proposed relationships. In order to test the model, we collected data from the purchasers of botanical cosmetics products that came from several different countries. A total of 798 users participated in the survey (425 users of domestic brands and 373 users of foreign brands). We performed several analyses related to the measurement model such as reliability analysis (Cronbach’s alphas), confirmatory factor analysis, and correlations analysis. Using SPSS 21.0 and AMOS 21.0, we estimated the structural model. The overall model fit indices include: χ2=1118.934 with df=239, p=0.000; GFI=0.884; AGFI=0.855; NFI=0.924; CFI=0.934; RMSEA=0.068; RMR=0.069. The study finds that all elements of SGCC, with the exception of social prestige, have a significant influence on affective commitment. Specifically, conformity to consumer trend is found to have a significant effect on affective commitment. This means that consumers who conform to the global trend tend to have a higher level of commitment. One implication is that cosmetics firms may want to communicate to the consumers that their products fit the lifestyle corresponding to the global trend. Contrary to our expectation, social prestige is not found significantly related to affective commitment. It seems that social prestige is not an important factor in choosing botanical cosmetics products. This is understandable because, unlike some prestige products that consumers wear or use to be associated with their image or perceived quality (e.g., car, handbag), consumers may not purchase botanical cosmetics products to upgrade their social status. As expected, quality perception has a significant positive effect on affective commitment. The study shows that quality perception has the most significant impact on affective commitment. Corporate social responsibility (CSR) is also found to have a significant impact on affective commitment. The finding suggests that companies should be or remain active in taking initiatives that advance social welfare. Our study shows that both affective and behavioral commitments are positively related to customer loyalty. Behavioral commitment, which consists of items representing purchase tendency, has a greater influence on loyalty than affective commitment. We anticipated that country of origin (COO) would moderate the proposed relationships. We find no significant moderating effect of COO. This can be interpreted that the structural relationships are upheld regardless of COO. It seems that global consumers evaluate foreign brands in the same manner as they do domestic brands. This suggests that cosmetics firms may want to be careful in differentiating their strategies based on countries as the return on investment may not be as handsome as they thought and global consumers may have more similarities than differences with respect to how they evaluate and purchase cosmetics products.

The cabbage whitefly Aleyrodes proletella L. (Hemiptera: Aleyrodidae) is a specialized insect that uses its mouthparts(stylets) to feed from the phloem of its host plants, which are found among the Brassicaceae and Asteraceae. Female whiteflies lay their eggs in circular patterns embedded in wax on the underside of the leaves. These were collected from the leaf of triangular lettuce, Crepidiastrum sonchifolium throughout the whole Chungnam province, 2013. We reared the cabbage whitefly on the egg-plant. The elongate-oval eggs are laid upright in a semicircle on the underside of Brassica leaves but didn’t in lab. Initially pale and translucent, the eggs become darker. Nymphs are scale-like and covered with wax; their color is white with two yellow spots on the abdomen. On the dorsal surface of the last abdomial segment is the vasiform orifice charactersitic of the group. The fourth instar is called the “pupa”. The pupa is thicker, immobile, and pale in color with red eyes. The adults are tiny, about 1.5 mm long, and moth-like. The head and thorax are dark. The abdomen is yellow and covered by a conspicuous white waxy layer. The forewings have a faint, dark bar. If disturbed, the adults fly readily. The duration of development of immature stages of Aleyrodes proletella decreased with increase in temperature, the mortality was higher below 16 ℃ and above 28 ℃.
