title: Clinical efficacy of biocellulose wound dressing containing silk sericin and polyhexamethylene biguanide for split-thickness skin graft donor sites

description: A biocellulose wound dressing composed of silk sericin as an accelerative wound healing component and polyhexamethylene biguanide (PHMB) as an antimicrobial agent which showed effective and safe wound treatment. A prospective, single-blinded, randomized controlled matched-pair study was designed to evaluate the safety and the clinical efficacy of the biocellulose wound dressing containing silk sericin and PHMB compared with Bactigras® in healthy volunteers (phase I clinical study) and in split-thickness skin graft (STSG) donor site wound treatment (phase II clinical study). There were 105 healthy volunteers in phase I clinical study. The results showed that the erythema and melanin levels of skin covered with both dressings were not significantly different. In the phase II clinical study, 21 patients with 32 STSG donor site wounds were included in the study. The wound healing time was not significantly different between dressings. The melanin levels, erythema levels, and TEWL levels of the group treated with the biocellulose wound dressing were significantly lower than the control group. No signs of infection and adverse effect were observed in wounds covered with either dressing. The pain scores of wounds covered with the biocellulose wound dressing were significantly lower than Bactigras® at days 1 to 5. In conclusion, the biocellulose wound dressing containing silk sericin and PHMB exhibits safety and many benefits including high scar quality, pain reduction, infection protection without adverse events. It is appropriate for use as an alternative treatment for STSG donor site wounds.

title: Bioactive compounds from dendrobium infundibulum

description: Phytochemical study of the methanol extract from Dendrobium infundibulum (Orchidaceae) led to isolation of nine pure compounds including two new compounds (dendroinfundin A and dendroinfundin B) and seven known compounds (ephemeranthol A, moscatilin, aloifol I, batatasin III, 3,3'-dihydroxy-4,5-dimethoxybibenzyl, 3,4'-dihydroxy-3',4,5-trimethoxybibenzyl and dendrosinen B). Their structures were determined from their spectroscopic data. All compounds were then examined for their lipase and alpha-glucosidase inhibitory activities. Dendrosinen B (IC50 = 295.0±37.9 µM) showed moderate inhibitory activity against lipase when compared with orlistat (IC50 = 31.4±0.6 nM). Strong anti alpha-glucosidase agents were batatasin III (IC50 = 148.8±8.4 µM) and dendrosinen B (IC50 = 213.9±2.4 µM), which were more potent than acarbose (IC50 = 809.1±22.2 µM).

title: Development and Dynamics of the Informal Workers in Thailand: A Case Study of Informal Workers Network

description: This thesis aims to analyze the informal worker movement that is associated with a labor NGO named HomeNet Thailand, which helped mobilize informal workers and strengthen their skills and knowledge. The core analysis of thesis follows Resource Mobilization Theory and Political Process Theory to analyze the informal workers' developments, conditions, and limitations. This thesis explores the Informal workers' situation during Yingluck Shinawatra's civilian government (2011-2014) and Prayut Chan-o-cha's miliatry government (2014-Present). The thesis consists of 5 parts. Firstly, an introduction elaborates the research methodology of Archival Research and Interview methods. Secondly, a literature review and theoretical framework show the limitations of prior research and connectivity between this research and the analytical frameworks. Thirdly, it studies HomeNet and its informal worker groups’ origins, development, sytematization and mobilization via Resource Mobilization Theory. Fourthly, it analyzes HomeNet informal workers’ political engagement under two different regimes, focusing on the dynamics and limitations within the group via Political Process Theory. Lastly, the conclusion elaborates how the relationship between the movement’s resource mobilization and external political structures can determine the movement’s success and failure. The thesis argues that with the pre-existing network and attempts to draw popularity by Yingluck’s government from having civilians participated in politics led the informal sector to their further developments. While on the other hands, the military government – if not interest in informal sector – could halt the development progress of the sector.

title: Singaporean Malays' Perspectives of Income Inequality and its Impact on their Opportunities in Singapore’s Education System

description: Studies on the profile of income inequality revealed that Singaporean Malays continuously occupied the lowest income strata and fared relatively poorer in their academic performance compared to other races. In a highly competitive meritocratic education system that rewards relative merit, yet neglects how unequal backgrounds provided unfair starting points for some, such low-income Malay households may appear to be systemically disadvantaged by income inequality and their access to better education. Under these circumstances, income inequality is further perpetuated. Through the use of focus group discussions and in-depth interviews, my proposed research will seek to understand how Singaporean Malays perceive such income inequality and its adverse impact on their education. In addition, this paper offers insights on what their perceptions could mean. It is hoped that these insights will complement the findings from other academics and point the way to how best engage the Malay community, to improve their lives and help them meet their aspirations despite the inherent challenges they may face and to assure them that they have an equal stake in Singapore's future.

title: Who Governs the Wasteland? Bangkok’s Informal Recycling Sector in Urban Waste Management

description: Amidst rapid population growth and urbanization, municipalities confront many challenges posed by waste generation, and its subsequent collection and disposal. In light of these challenges, an integrated solid waste management has emerged as an alternative and more holistic approach to tackling waste challenges, including a more serious consideration of power dynamics and relationships between different actors and interests. Integrated solid waste management in developing countries further reveals an active informal sector and various practices of informality in resource recovery and recycling. Yet, it remains unclear if solid waste management systems can further integrate the informal sector in such a way that will promote co-benefits in the form of more economic efficiency, less environmental pollution and higher recycling rates, and greater livelihood and social equity, particularly for those employed in the informal sector. This thesis examines the politics of urban governance and development through the case of solid waste management in the Bangkok Metropolitan Area, Thailand. It employs a discourse analysis to discern the power relations embedded within the discourses around informality, particularly in terms of who benefits and loses within the city’s solid waste management system and practices. This study primarily draws its data from 17 in-depth, unstructured interviews with waste actors in Bangkok from national and local governments, private companies, international organizations, NGOs, academics, media, and the informal recycling sector. The central finding from this study shows how informal practices and waste actors operate under a liberal economic logic in which waste is principally redefined from a problem into a resource and in which the informal sector plays a critical role in rendering waste into an economically valuable good.

title: TREADING WATER: AN ETHNOGRAPHY OF THE PLIGHT AND CAPABILITIES OF AFGHAN REFUGEES IN INDONESIA

description: ACCORDING TO THE 2016 UNHCR STATISTICS, THERE ARE OVER 14,000 REFUGEES TRAPPED IN INDEFINITE TRANSIT IN INDONESIA, WITH FAINT HOPE OF EVER BEING RESETTLED TO ANY THIRD COUNTRY. THE WEST JAVA TOWN OF CISARUA ALONE HOSTS NEARLY 5,000 REFUGEES FROM THE ETHNIC HAZARA MINORITY GROUP FROM AFGHANISTAN. IN THEIR INTRACTABLE LIMBO, A GROUP OF THESE HAZARAS HAVE SET UP A NUMBER OF REFUGEE RUN LEARNING CENTRES AND COMMUNITY INITIATIVES, CREATING FOR THEMSELVES MEANING AND PURPOSE DURING THEIR UNBOUNDED TRANSIT. THIS TOWN AND POPULATION REPRESENT A UNIQUE CASE STUDY IN REFUGEE RESILIENCE, TRANSFORMATION, AND EMPOWERMENT IN LIGHT OF A DEEPENING GLOBAL REFUGEE CRISIS. USING A CAPABILITIES FRAMEWORK AND SOCIAL CAPITAL THEORY, THIS THESIS EXAMINES THE EMERGENCE OF THESE REFUGEE RUN INSTITUTIONS, AND THE IMPACT THAT INVOLVEMENT WITH THESE INSTITUTIONS HAS ON REFUGEES IN PERPETUAL TRANSIT. THE RESEARCH EMPLOYS ETHNOGRAPHIC, QUALITATIVE METHODS IN ORDER TO SHARE THE STORIES AND EXPERIENCES OF SOME OF THE MOST VULNERABLE AND FORGOTTEN MEMBERS OF SOCIETY IN THEIR JOURNEY TO EMPOWERMENT. THE ANALYSIS OF THIS STUDY CONCLUDED THAT THE SOCIAL CAPITAL BUILT THROUGH INVOLVEMENT WITH REFUGEE RUN INITIATIVES IS THE CONVERSION FACTOR THAT CHANGES LIVES; COMMUNITY ITSELF IS THE TRANSFORMATIVE ELEMENT. THROUGH THIS TRANSFORMATION, REFUGEES HAVE CREATED FOR THEMSELVES MEANING AND PURPOSE DURING THEIR INDEFINITE TRANSIT, AND LAID PATHWAYS FOR A SUCCESSFUL FUTURE.

title: EXPRESSION AND CHARACTERIZATION OF α-GLUCOSIDASE FROM Weissella confusa BBK-1

description: Alpha-glucosidase [EC 3.2.1.20; α-D-glucoside glucohydrolase] is an exohydrolase which catalyzes non-reducing end of substrates to release D-glucose. In addition, alpha-glucosidase also displays a transferase activity, which bring about the formation of α-glucosylated compounds such as soluble starch and glycogen. This research aims to express and characterize α-glucosidase from Weissella confusa BBK-1 (WcAG). WcAG gene was expressed in modified pET28b vector. This gene contained an open reading frame of 1,775 bps. Optimum expression condition of WcAG was cultured in LB medium containing 1% (w/v) glucose and induced with 0.4 mM IPTG at 20°C for 20 h. The recombinant WcAG containing his-tag at the C-terminus was successfully purified by His-Trap column with the specific activity of 45.29 U/ml, purification fold of 2.93 increased with 21.65% yields of total activity. WcAG had molecular mass of 124 kDa and existed as dimer in native form. For hydrolysis activity, the optimum temperature and pH were at 50 ºC and pH 6.0, respectively. Temperature and pH stability of WcAG were in range of 4 to 40 °C, and pH 6.0-8.0 in phosphate buffer, respectively. The most suitable substrate for hydrolysis activity of WcAG was maltotriose (G3) while maltose (G2) was for transglycosylation activity. For hydrolysis activity, the order of preferable substrate was maltotriose (G3), maltotetraose (G4), maltopentaose (G5), maltohexaose (G6) and maltose (G2), respectively. For kinetic study of WcAG, the apparent Km, kcat and kcat/ Km values for G3 substrate were 2.67 mM, 14.096 s-1 and 5.279 (s·mM)-1, respectively. The apparent Km, kcat and kcat/ Km values for G2 substrate were 16.22 mM, 0.738 s-1 and 0.046 (s·mM)-1, respectively. The optimal maltooligosacharide production was obtained of incubation using 200 mM of G2 with 0.4 unit/ml of WcAG at 37 ºC for 24 h. Four products were obtained from transglycosylation activity including product I, II, III and IV. Identification of all products using HPAEC-PAD revealed that product I was isomaltose, product II was panose while product III and IV still cannot be identified.

title: Tyrosinase inhibitors from sapodilla plum Manilkara zapota L.

description: Six different parts of Manilkara zapota which consisted of barks, flowers, fruits, leaves, roots and seeds were investigated for total phenolic content, total flavonoid content, antioxidant and antityrosinase activities. Methanol crude extract of flowers showed the highest total phenolic content (368.73 ± 0.65 mg GAE/g), while methanol crude extracts of seeds and roots showed high total flavonoid content (90.21 ± 0.57 and 89.03 ± 1.00 mg QE/g, respectively). Methanol crude extract of seeds showed the strongest DPPH (IC50 282.05 ± 0.60 μg/mL) and ABTS (IC50 205.11 ± 0.89 μg/mL) radical scavenging activities and showed the highest FRAP value of 296.46 ± 0.08 mg TEAC/mg. Methanol crude extract of roots showed the highest tyrosinase inhibitory activities on both monophenolase (IC50 0.81 ± 0.92 mg/mL) and diphenolase inhibitory activities (IC50 0.55 ± 0.50 mg/mL). Total phenolic content and antioxidant radical activities showed high correlation by ABTS, DPPH and FRAP assays. Correlations between total phenolic content with antityrosinase activities and with total flavonoid content were very low. A low correlation was found between total total flavonoid content and antioxidant activities by DPPH, ABTS and FRAP assays. There were no correlation between total flavonoid content with antityrosinase activities and no correlation between antioxidant and antityrosinase activities. Moreover, bioassay-guided fractionation on tyrosinase inhibitory activity was used to isolate tyrosinase inhibitors from M. zapota barks. Separation of n-hexane and ethyl acetate crude extracts of M. zapota barks afforded seven isolated compounds; taraxerol methyl ether (I), 6-hydroxyflavanone (II), (+)-dihydrokaempferol (III), 3,4-dihydroxybenzoic acid (IV), taraxerol (V), taraxerone (VI) and lupeol acetate (VII). (+)-Dihydrokaempferol (III) displayed significant tyrosinase inhibition (IC50 32.17 ± 0.32 μM) against monophenolase activity which was more potent than kojic acid (IC50 40.21 ± 0.63 μM). Furthermore, (+)-dihydrokaempferol (III) (IC50 31.60 ± 0.73 μM) showed similar activity on diphenolase inhibitory activity when compared with kojic acid (IC50 30.07 ± 0.32 μM). Furthermore, isolated compounds I-VII were evaluated antioxidant and cytotoxic activities. (+)-Dihydrokaempferol (III) exhibited the strongest scavenging activities on DPPH (IC50 2.21 ± 0.77 μM) and ABTS (IC50 214.83 ± 0.51 μM) and showed the highest FRAP value of 6.23 ± 0.10 μM. It displayed strong cytotoxic activity against human cancer cell lines; BT474, ChaGo-K-1, HepG2, KATO-III and SW620 with IC50 values of 11.66 ± 0.42, 12.32 ± 0.73, 13.67 ± 0.38, 39.79 ± 0.38 and 41.11 ± 1.08 μM, respectively. This study indicated that M. zapota might constitute a rich source of total phenolic contents and natural antioxidants. Moreover, (+)-dihydrokaempferol (III) could be developed as a natural tyrosinase inhibitor.

title: Fluoride encapsulation in calcium matrix

description: Fluoride ion (F-) is an important ingredient in a toothpaste. It protects caries by reacting with hydroxyapatite [Ca10(PO)4(OH)2] in tooth enamel to form insoluble fluorapatite [Ca10(PO)4(F)2]. Unfortunately, F- also easily interacts with calcium species in a toothpaste, and then it is deactivated. In this work, we focus on the encapsulation of F- in a shellac bead by using a simple extrusion method. To construct shellac beads, an aqueous solution of F- is injected into an ethanolic solution of shellac. The shellac beads are formed due to insolubility of shellac in water. Then, the beads are transferred into DI water for hardening a bead wall via a diffusion of ethanol in the bead wall to an aqueous phase. The bead formation mechanism is investigated using infrared spectroscopy. The process is also optimized by varying shellac concentration, shellac-dissolution time, bead-formation time, and bead-hardening time. The average size of F--encapsulated shellac beads is 2.59 ± 0.33 mm. Active F- is completely released from shellac beads after immersed in DI water for 14 days. Surprisingly, after immersed in 5 % CaCl2, the beads can encapsulate the active F- for, at least, 3 months with the percentage of active F- remaining in the beads of 71.03 ± 4.18 %. It is because CaF2 can block releasing channels of active F- on the bead surface.

title: Synthesis and properties of acrylonitrile-butadiene-styrene copolymer containing silica nanoparticles

description: The aim of this research is to develope acrylonitrile butadiene styrene composite reinforced with hydrophobic silica nanoparticles. In this study, in-situ synthesis of ABS rubber particles containing hydrophobic silica nanoparticles (HDTMS-silica) was carried out. Firstly, three of HDTMS-silicas (HDTMS-silica1, HDTMS-silica2, and HDTMS-silica3) were prepared by silanization of SiO2 nanoparticle with hexadecyltrimethoxysilane (HDTMS : SiO2 wt ratios of 1 : 1, 2 : 1, and 3 : 1) in an emulsion system. Then, HDTMS-silica/styrene and acrylonitrile mixture was fed into a polybutadiene latex reactor. Following that, graft copolymerization was carried out using persulfate initiator at temperature of 65 oC for 3.5 h. Thus obtained ABS rubber containing HDTMS-silica was melt extruded with styrene-acrylonitrile (SAN) to prepare ABS nanocomposite compound. Mechanical properties of ABS nanocomposite compounds were evaluated. It was found that all of HDTMS : SiO2 wt ratios produced hydrophobic SiO2 nanoparticles exhibiting good dispersibility in toluene test. In fact, 3 :1 HDTMS : SiO2 showed the complete hydrophobicity modification, judged by the absence of silanol absorption band. However, the optimum mechanical properties were achieved at 2 wt% loading of 2 : 1 HDTMS : SiO2. Below 2 : 1 ratio, the HDTMS ratio was not enough to obtain the fully hydrophobic surface modification. Above 2: 1 ratio, the excessive HDTMS ratio led to a decrease in SiO2 content judged by Si EDX mapping, causing a gradual decrease in its energy absorption and reinforcement performance. In case of 2 : 1 HDTMS : SiO2, optimum mechanical properties were achievable at 2 wt% HDTMS-SiO2 loading, resulting from the optimum dispersibility of HDTMS-SiO2 nanoparticles. Further increase in HDTMS-SiO2 loading resulted in a reverse effect due to agglomeration problem. Moreover, the ABS-g-MAA and ABSSi-g-MAA were successfuly prepared and then melt-mixed with PLA to obtain PLA/ABS-g-MAA and PLA/ABSSi-g-MAA blends using an internal mixer. The impact strength of the blends is dependent on the percent loading of ABS-g-MAA and ABSSi-g-MAA. The percent loading of ABS-g-MAA and ABSSi-g-MAA played and important role in control the flexibility of the blends.
