Self-cleaning Property of Polyester Fabrics Finished with 3DOM TiO2
Panida Joomjarearn,Supakit Achiwawanich,Jantip Setthayanond,Potjanart Suwanruji 한국섬유공학회 2020 Fibers and polymers Vol.21 No.9
Three-dimensionally ordered macroporous titanium dioxide (3DOM TiO2) was prepared by a sol-gel methodusing poly(methyl methacrylate) as a template. The synthesized 3DOM TiO2 was finished on poly(ethylene terephthalate)and poly(lactic acid) fabrics by a pad-dry-cure method to enhance self-cleaning properties. Discoloration of curcumin,carmoisine and methylene blue stains on finished fabrics under UVA irradiation was examined to evaluate its self-cleaningabilities. The results showed that 3DOM TiO2 on the finished fabrics could diminish the stains in a higher degree as comparedto the unfinished fabrics and fabrics finished with TiO2 nanoparticles. Dyeing properties of polyester fabrics with C.I. Disperse Red 60 were slightly affected by 3DOM TiO2. Color strength (K/S) and wash fastness of the 3DOM TiO2 finishedfabrics were a little lower than the unfinished counterparts.
Intestinal microbiota and the immune system in metabolic diseases
Panida Sittipo,Stefani Lobionda,이윤경,Craig L. Maynard 한국미생물학회 2018 The journal of microbiology Vol.56 No.3
The intestinal microbiota is comprised of millions of microorganisms that reside in the gastrointestinal tract and consistently interact with the host. Host factors such as diet and disease status affect the composition of the microbiota, while the microbiota itself produces metabolites that can further manipulate host physiology. Dysbiosis of the intestinal microbiota has been characterized in patients with certain metabolic diseases, some of which involve damage to the host intestinal epithelial barrier and alterations in the immune system. In this review, we will discuss the consequences of dietdependent bacterial dysbiosis in the gastrointestinal tract, and how the associated interaction with epithelial and immune cells impacts metabolic diseases.

The effects of methyl jasmonate (MeJA) as a protectant against chilling injury on physicochemical qualitiesof ‘Trad-see-thong’ pineapple (‘Queen’ group) fruit was investigated. The pineapple fruit were immersed in 1 mMMeJA for 5 min and then stored at 10 ± 1°C for 20 days. MeJA had no effect on respiratory rate and pulp colour,but suppressed ethylene production during cold storage. Weight loss, ion leakage (IL), internal browning (IB), andloss of pulp firmness were inhibited by MeJA. The MeJA treatment also suppressed the reduction of lightness (L*)and yellowness (b*) and the increase of total phenols (TP) that commonly occurs during cold storage, and increasedthe polyphenol oxidase (PPO) activity of pulp adjacent to the core (PAC) tissue. Certain bioactive compounds, suchas ascorbic acid (AsA) and superoxide dismutase (SOD) in PAC tissues were enhanced by MeJA. No significantdifference in peroxidase (POD) activity in both pulp and PAC tissues were detected between the treated and controlfruits. These results suggest that immersion in MeJA is an effective means to maintain quality, alleviate IB symptoms,and enhance certain bioactive compounds in ‘Queen’ pineapple fruit cv. Trad-see-thong during cold storage.

The presence of phenols in treated palm oil mill effluent (POME) is an environmental concern due to their phytotoxicity and antimicrobial activity. In this study, phenol-degrading bacteria, Methylobacterium sp. NP3 and Acinetobacter sp. PK1 were immobilized on oil palm empty fruit bunches (EFBs) for removal of phenols in the treated POME. The bacterial exopolysaccharides (EPS) were responsible for cell adhesion to the EFBs during the immobilization process. These immobilized bacteria could effectively remove up to 5,000 mg/L phenol in a carbon free mineral medium (CFMM) with a greater degradation efficiency and rate than that with suspended bacteria. To increase the efficiency of the immobilized bacteria, three approaches, namely activation, acclimation, and combined activation and acclimation were applied. The most convenient and efficient strategy was found when the immobilized bacteria were activated in a CFMM containing phenol for 24 h before biotreatment of the treated POME. These activated immobilized bacteria were able to remove about 63.4% of 33 mg/L phenols in the treated POME, while non-activated and/or acclimated immobilized bacteria could degrade only 35.0%. The activated immobilized bacteria could be effectively reused for at least ten application cycles and stored for 4 weeks at 4°C with the similar activities. In addition, the utilization of the abundant EFBs gives value-added to the palm oil mill wastes and is environmentally friendly thus making it is attractive for practical application.

Purpose: The current study focused on developing Klong Kone Shrimp Paste (Mesopodopsis) products and packaging, aiming to enhance the capabilities of entrepreneurs with cultural capital in post-pandemic Samut Songkhram Province. Research design, data and methodology: This study sought to analyze product and packaging issues and examine packaging expectations for Klong Kone shrimp paste. A combination of quantitative and qualitative methods was used, including a questionnaire administered to a sample of 400 individuals who purchased community enterprise products. Descriptive analysis, involving percentage, mean, and S.D., along with qualitative analysis through phenomenological methods, such as in-depth interviews and focus groups, were conducted with community enterprise entrepreneurs, experts, and customers. Results: The findings indicate that addressing product conditions and packaging issues with Klong Kone shrimp paste can be achieved by incorporating an attached label on the community product packaging. Conclusion: This approach is necessary due to the lack of community identity reflection and unattractive design, which currently deter customers from considering the products as souvenirs. Additionally, diversifying product offerings is recommended to better align with consumer needs. In terms of packaging expectations, a majority of respondents expressed a strong preference for an attractive appearance.
Matching the Moor with the Maestro: Adaptations and Stage Productions of Othello in Thailand
Panida Boonthavevej 한국셰익스피어학회 2014 셰익스피어 비평 Vol.50 No.5
The paper discusses the cultural contexts of two adaptations of Othello in Thailand. While Damkerng Thitapiyasak’s “otHELLO: A Match of Jealousy” places its story in a contemporary setting with the contention of Thai Premier League in the forefront, Somtow Sucharitkul directs and conducts Giuseppe Verdi’s Otello by integrating Phaya Rachawangsan, the 1913 adaptation of Othello by Vajiravudh (r.1910-1925). The opera juxtaposes the aurality of the Italian libretto with the visuality of Srivijayan costumes and sets. Arguably, both stage productions of Othello are cultural phenomena in which diverse articulations of the global culture in the local scene may be deployed to question the untainted authenticity of the local and to illuminate the constructedness of the distinction between the local and the global. Furthermore, a comparative study of the two productions accentuates the process of artistic and social positioning that in effect incurs different perceptions of the play ? high culture or pop culture ? among the audience who are consumers of cultural products.

This study aimed to modify behavior regarding liver fluke and cholangiocarcinoma prevention in Chumphuang district, Nakhon Ratchasima province, Thailand through integrated learning. A total of 180 participants were included through purposive selection of high-risk scores on verbal screening. Participants attended the health education program which applied the health belief model included family based, knowledge station based, academic merit based and community based learning. Data were collected using a questionnaire composed of 4 parts: 1) personal information, 2) knowledge, 3) perceived susceptibility, severity, benefits, and barriers, 4) practice regarding liver fluke and cholangiocarcinoma prevention. The result revealed that the majority were female (79.9%), age ${\geq}60$ years old (33.2%), primary school educational level (76.1%), and agricultural occupation (70.1%). The mean scores of knowledge, perception, and practice to liver fluke and cholangiocarcinoma prevention, before participated the integrative learning were low, moderate, and low, respectively. Meanwhile, the mean score of knowledge, perceived susceptibility, severity, benefits, and barriers, and practice regarding liver fluke and cholangiocarcinoma prevention, were higher with statistical significance after participation in the integrated learning. This finding indicates that health education programs may successfully modify health behavior in the rural communities. Therefore they may useful for further work behavior modification in other epidemic areas.
Liver Fluke-Associated Biliary Tract Cancer
( Piyapan Prueksapanich ),( Panida Piyachaturawat ),( Prapimphan Aumpansub ),( Wiriyaporn Ridtitid ),( Roongruedee Chaiteerakij ),( Rungsun Rerknimitr ) 대한간학회 2018 Gut and Liver Vol.12 No.3
Cholangiocarcinoma (CCA) is an aggressive cancer arising from epithelial cells of the bile duct. Most patients with CCA have an unresectable tumor at the time of diagnosis. In Western countries, the risk of CCA increases in patients with primary sclerosing cholangitis, whereas liver fluke infection appears to be the major risk factor for CCA in Asian countries. A diagnosis of liver fluke infection often relies on stool samples, including microscopic examination, polymerase chain reaction-based assays, and fluke antigen detection. Tests of serum, saliva and urine samples are also potentially diagnostic. The presence of liver fluke along with exogenous carcinogens magnifies the risk of CCA in people living in endemic areas. The “liver fluke-cholangiocarcinoma” carcinogenesis pathways consist of mechanical damage to the bile duct epithelium, immunopathologic and cellular reactions to the liver fluke’s antigens and excretory/secretory products, liver fluke-induced changes in the biliary tract microbiome and the effects of repeated treatment for liver fluke. A vaccine and novel biomarkers are needed for the primary and secondary prevention of CCA in endemic areas. Importantly, climate change exerts an effect on vector-borne parasitic diseases, and awareness of liver fluke should be enhanced in potentially migrated habitat areas. (Gut Liver 2018;12:236- 245)
New bacterium symbiont in the bacteriome of the leafhopper Yamatotettix flavovittatus Matsumura

The leafhopper Yamatotettix flavovittatus Matsumura is the vector of the phytoplasma pathogen that causes white leaf disease in sugarcane crops. This study aimed to identify the bacterial symbionts associated with Y. flavovittatus by amplifying, cloning, and sequencing their 16S rRNA genes. Two types of bacteria were present; one is Candidatus Sulcia muelleri (Bacteroidetes), a well-known ancient primary symbiont found in a diverse range of insects in Auchenorrhyncha suborder. The other is a member of Gammaproteobacteria that differed from all other members deposited in the GenBank database and was therefore named Candidatus Yamatotia cicadellidicola. These bacteria were present throughout the leafhopper life cycle and were found in 100% of the natural host populations examined. Fluorescent in situ hybridization analysis revealed that these bacteria were co-localized in the same bacteriome and present in the full-grown oocyte. Our main finding suggests the Ca. Y. cicadellidicola is a new type of symbiont that co-occurs with Ca. S. muelleri in the leafhopper Y. flavovittatus (Deltocephalinae subfamily).
