Pistagremic acid (PA) is a bioactive triterpenoid isolated from various parts of Pistacia integerrima plants. The aim of this research was to investigate PA for reversion of multidrug resistant (MDR) mediated by P-glycoprotein using rhodamine-123 exclusion study on a multidrug resistant human ABCB1 (ATP-binding cassette, sub-family B, member 1) gene-transfected mouse T-lymphoma cell line in vitro. Results were similar to those with verapamil as a positive control. Docking studies of PA and standard Rhodamine123 were carried out against a P-gp crystal structure which showed satisfactory results. Actually, PA cannot bind exactly where co-crystallized ligand of P-gp is already present. However, the docking study predicted that if a compound gives a lesser score then it may have some potency. The docking scores of PA and Rhodamine were similar. Therefore, we can conclude that there are certain important chemical features of PA which are responsible for the inhibiting potency of P-gp.

Background: This study assessed parental experiences with chemotherapy-induced alopecia among children with cancer treated at an Indonesian academic hospital. Materials and Methods: Fifty parents of childhood cancer patients were interviewed using semi-structured questionnaires. Results: The moment that hair fell out was the moment that parents (84%) had to admit their child had cancer. Alopecia was a traumatizing painful experience (46%). Active strategies to hide alopecia, mainly hats, were used by 66% of children, while 34% never covered their bald head. If money had not been an issue, 40% would use another strategy. Alopecia made children limit outdoor daily activities (78%) and engagement with others (60%). Significantly more children from high-educated (95%) than low-educated (60%) parents received sympathy from other people (P=0.012). Significantly more Christian (29%) than Muslim (0%) families confirmed that alopecia lowered the quality of life (P=0.046). Most parents (82%) had no prior plans about alopecia management, yet for significantly more girls (26%) than boys (0%) such plans existed (P=0.044). Parents received most information about alopecia from other parents (66%). Parents (92%) needed more alopecia education from doctors. Of all school-attending children, 53% were bullied and 47% did not want to attend school due to alopecia. Significantly more high-educated than low-educated families received pity from teachers and pupils (94% vs. 0%, P=0.004), and acceptance by pupils (81% vs. 0%, P=0.021). Conclusions: Alopecia is a severe, far-stretching side-effect of chemotherapy with physical, psychological and social consequences for children and parents. Parents should be better informed about occurrence and impact of alopecia. Extra attention is required to facilitate children's return to school. Healthcare providers should facilitate optimal supportive care through open dialogue and provision of educational m aterials for parents, children and their community.

The Indonesian population is estimated at 250 million and ranked as the world's fourth-largest. It is also one of the world's largest Muslim nations. Seventy percent of the population of Indonesia is young consumers in their 20s and 30s. In additions, Indonesian consumers have recently developed a great interest in fashion in general and Korean fashion in particular. This paper addresses issues related to young Indonesian consumers' clothing behavior in terms of clothing image, clothing style, body image, clothing and attitudes toward Korean fashion brands. The survey method was used as a primary research instrument. All measurements were adapted from the existing scales from previous studies. A total of 172 questionnaires were used for the final statistical analysis. Empirical results showed that Indonesian consumers' preferences regarding clothing image were new, casual, humorous, futuristic, soft, interesting and active. In terms of style, Indonesian consumers scored high in their preferences of casual and classic styles. With regard to body image, Indonesian consumers have significant concern for their appearance and body, but at the same time they are more satisfied with their body shape. More than half of the respondents had experience in purchasing Korean fashion products. Indonesian consumers recognized the clothing image of Korean fashion brands as new, futuristic, and hi-tech. Furthermore, they perceive the clothing style of Korean fashion brands as casual, feminine, and sexy. Korean fashion brand purchase intension was significantly influenced by recognition and preference of Korean fashion brand.

The purpose of this study was to provide basic data for development of a recipe for muslim-friendly halal Korean foods through investigation of awareness of Korean foods, taste evaluation, and menu preferences. After Korean foods' menu range and standard were set up for the survey and in-depth interviews with three halal food experts were conducted, 35 kinds of halal Korean foods were examined. The present study conducted a survey on 205 foreign Muslims living in Jeonju-si, Jeonbuk and Gimpo-si, Gyeonggi who ate Korean foods. Foreign Muslims were male workers in their 20's residing in company housing, and their monthly mean income was 1.01~2 million KRW. The majority of subjects responded that meal problems were the most difficult in everyday life. Concerning the taste of Korean foods, the response rate of 'sweet' and 'spicy' was high while 'Korean food is healthy' and 'Korean food ingredients is fresh' were high for awareness of Korean foods. 'Bulgogi' was the most preferred among the selected Korean foods, which was in line with the results of previous research. There is a need to provide information on Korean foods that can be made with food ingredients certified as halal and their recipes through various media for foreign Muslims who have limitations on in meals due to religious factors.

Methyl ester derived from coconut oil is very interesting to study since it contains free-fatty acid with chemical structure of medium carbon chain ($C_{12}-C_{14}$), so the methyl ester obtained from its part can be a biodiesel and another partially into biokerosene. The use of heterogeneous catalysts in the production of methyl ester requires severe conditions (high pressure and high temperature), while at low temperature and atmospheric conditions, yield of methyl ester is relatively very low. By using microwave irradiation trans-esterification reaction with heterogeneous catalysts, it is expected to be much faster and can give higher yields. Therefore, we studied the production of methyl ester from coconut oil using CaO catalyst assisted by microwave. Our aim was to find a kinetic model of methyl ester production through a transesterification process from coconut oil assisted by microwave using heterogeneous CaO catalyst. The experimental apparatus consisted of a batch reactor placed in a microwave oven equipped with a condenser, stirrer and temperature controllers. Batch process was conducted at atmospheric pressure with a variation of CaO catalyst concentration (0.5; 1.0; 1.5; 2.0, 2.5%) and microwave power (100, 264 and 400 W). In general, the production process of methyl esters by heterogeneous catalyst will obtain three layers, wherein the first layer is the product of methyl ester, the second layer is glycerol and the third layer is the catalyst. The experimental results show that the yield of methyl ester increases along with the increase of microwave power, catalyst concentration and reaction time. Kinetic model of methyl ester production can be represented by the following equation: $-r_{TG}=1.7{\cdot}10^6{_e}{\frac{-43.86}{RT}}C_{TG}$.

Purpose - Based on complexity theory, this study develops a configurational model to predict the profitability of Halal cosmetics firms in the Indonesian and Malaysian markets. The proposed research model involves two level configurations-industry context and selling strategies-to predict high and low scores of a firm's profitability. The industry context configuration model comprises industry stability, product homogeneity, price sensitivity, and switching cost. Selling strategies include customer-focused, competitor-focused, and margin-focused approaches. Design/methodology - This is the first empirical study that calculates causal models using a combination of industry context and selling strategy factors to predict profitability. Data obtained from the marketing managers of cosmetics firms are used to test the proposed configurational model using fuzzy-set qualitative comparative analysis (fsQCA). It contributes to the current knowledge of business marketing by identifying the factors necessary to achieve profitability using analysis of condition (ANC). Findings - The results revealed that unique and distinct models explain the conditions for high and low profitability in the Indonesian and Malaysian halal cosmetic markets. While customer-focused selling strategy is necessary to attain a higher profit in both the markets, margin-focused selling strategy appears to be an essential factor only in Malaysia. Complexity of the interactions of selling strategies with industry factors and differences between across two study markets confirmed that complexity theory can support the research configurational model. The theoretical and practical implications are also illustrated. Originality/value - Despite the rapid growth of the global halal industry, there is little knowledge about the halal cosmetic market. This study contributes to the current literature of the halal market by performing a set of asymmetric analytical approaches using a complex theoretical model. It also deepens our understating of how the Korean firms can approach the Muslim consumer's needs to generate more beneficial turnover/revenue.

Background: Profound anesthesia with adequate duration is required in periodontal flap surgery, which involves the manipulation of both hard and soft tissues. The anterior middle superior alveolar (AMSA) injection may be an alternative to multiple injections required for this purpose in the maxilla. The present study aimed to assess the effectiveness of AMSA injection using computer-controlled local anesthetic delivery (CCLAD) system to anesthetize buccal hard tissue (BHT), buccal soft tissue (BST), palatal hard tissue (PHT), and palatal soft tissue (PST) around the maxillary teeth. Methods: Thirty-five patients who were indicated for open flap debridement in a whole maxillary quadrant were given AMSA injection using the CCLAD. The effectiveness of anesthesia was evaluated using subjective and objective parameters around each tooth. Supraperiosteal infiltrations were administered to complete the surgery wherever the AMSA injection was ineffective. Results: The AMSA injection was more effective on the palatal tissues than on the buccal tissues, as 94.14% of PST and 87.89% of PHT sites were anesthetized compared to 49.22% and 43.75% of BHT and BST sites, respectively. There was no significant difference in the frequency of anesthesia around the anterior and posterior teeth. The PHT was significantly more anesthetized (P = 0.003) in males than in females. Conclusions: The AMSA injection using CCLAD is highly effective on palatal tissues and could be used as a first-line anesthesia for periodontal flap surgery. However, its effect on buccal tissues is less predictable, with supraperiosteal infiltration often required to supplement the AMSA injection.

In the Iranian epic $K{\bar{u}}shn{\bar{a}}ma$, there is a rather interesting story that recounts how the inhabitants of $B.s{\bar{i}}l\bar{a}$ cross-breed their domesticated horses with a magical horse living in the sea in order to obtain fine-bred ones. What is even more interesting is that similar accounts are also seen in many of other classical Perso-Arabic works and Chinese sources. The regions that such events took place in mainly spread over Central Asia and western China while in $K{\bar{u}}shn{\bar{a}}ma$, the story happens in $B.s{\bar{i}}l\bar{a}$, a legendary kingdom with its historical prototype being Silla. By sorting out certain records of how ancient people sought fine horses by cross-breeding domesticated horses with wild horses that inhabited mountains and waters within Chinese sources and classical Muslim works, and comparing these accounts with similar plot lines as depicted in $K{\bar{u}}shn{\bar{a}}ma$, this paper attempts to elucidate that the story in $K{\bar{u}}shn{\bar{a}}ma$ is a result of flourishing land and maritime exchanges between East Asia and West Asia during ancient and medieval times, rather than a purely literary fiction. It was not only influenced by the horse culture that thrived over the Eurasian Steppe, but the story is also coincidentally in accordance with the fact that the nomadic zone which lies within the central Eurasian continent extends as far as the Korean Peninsula in northeast Asia.
