title: Effects of selected volatile oils commonly used in Thailand on physiological activities and emotions

description: Nowadays, Volatile oils have been widely used in Thailand without much supporting scientific evidence. The objective of this study is was to investigate the effects of the commonly use volatile oil in Thailand, such as lavender oil, rosemary oil, jasmine oil and citronella oil on the nervous system, i.e. central nervous system (CNS), autonomic nervous system (ANS) as well as on emotional response after inhalation. Twenty subjects were tested for each essential oil. Totally eighty subjects were participated in this study. ANS parameters, i.e. blood pressure, heart rate, respiratory rate, and skin temperature were recorded. CNS was monitored by recording of brain electrical activities. Data were collected including frequency, Fast Fourier Transform value and topographical mapping. In addition, emotional responses were evaluated by visual analog scales. The effects of oils on the nervous system and emotional responses were determined by comparing the mean values between the oil and sweet almond oil. The paired t- test was used in this study. Correlation analyses between the nervous system and emotional responses were performed by Spearman rank-order correlation coefficient. Results demonstrate that lavender odor and citronella odor decreased the function of ANS. Lavender odor increased theta and alpha waves whereas citronella odor increased both alpha and beta waves. In contrast, rosemary odor and jasmine odor activated the function of ANS. Rosemary odor decreased alpha level and increased beta wave whereas jasmine odor increased beta wave. For emotional responses, subjects felt very good after inhalation all odors. The oils caused significant increases of enthusiasm, freshness and relaxation, when compared with sweet almond oil. Correlation between emotional responses and ANS showed a positive correlation between freshness and the increase of ANS function. In contrast, emotion of good, calm, drowsy had a negative correlation with ANS function. The correlation between emotional responses and brain wave showed both a positive correlation (relaxation and alpha brain wave) and a negative correlation (beta brain wave and relaxation). In terms of freshness, the correlation has been observed in opposite direction. Results from this study are able to be scientific knowledge of the effects of volatile oil on human body and emotion.

title: Water-soluble cationic branched phenylene-ethynylene as fluorescent probes for supramolecular interaction

description: Five amphiphilic fluorophores (N⁰N⁺, N⁺, 2N⁺, 3N⁺ and 6N⁺) with phenylene-ethynylene fluorogenic units are employed as the fluorescent probes for investigation of fluorescence responses in nano-confined environments of DNAs, BSA protein, surfactants and cyclodextrins in aqueous media. 3N⁺ represents one of the most responsive probes to all analytes. For example, the strong fluorescence enhancement of 3N⁺ by γ-cyclodextrin is due to a 1:1 stable inclusion complexation (K[subscript b] = 3.0x10⁴ M⁻¹). The discovery of fluorescence enhancement of 3N⁺ via charge interaction with ssDNA chain leads to the design of selective and sensitive potassium ion fluorescence aptasensing system. Strong fluorescence response to BSA protein suggest effective self-quenching prevention probably via both hydrophobic and hydrophilic interaction (K[subscript b] = 6.7x10⁵ M⁻¹). 3N⁺ is also used as a fluorescence micellization probe to determine CMC of surfactants. In the case of 6N⁺, the fluorescence enhancement becomes apparent only for BSA protein and surfactants. The interaction with ssDNA is proven by FRET signals which are useful for DNA sequence detection.

title: Biohydrogen production by nitrogen fixing cyanobacterium anabaena siamensis TISTR 8012

description: In this thesis,we focused to study biohydrogen production by using the cyanobacterium Anabaena siamensis TISTR 8012, a strain isolated from rice paddy field in Thailand. The phylogenetic analysis using 16S rDNA gene sequence revealed that A. siamensis TISTR 8012 is classified into a single group which possesses akinete and heterocyst differentiations when grown under N-deprivation. Optimum physical parameters to enhance growth rate of A. siamensis TISTR 8012 under N₂ fixing condition were temperature at 30 ℃, light intensity between 40-50 µE m⁻² s⁻¹ and pH 7.5. The efficiency of H₂ production depends on several factors, nitrogen compound available in medium and high salt stress could immediately decrease H₂ production in A. siamensis TISTR 8012. Optimizing key factors affecting H₂ production such as cell age, light intensity, time of light incubation and source of carbon resulted in enhanced H₂ production. The maximum H₂ production was about 32 µmolH₂ mg chl a⁻¹h⁻¹ when cells at log phase were adapted in BG11₀ medium without N-source supplemented with 0.5% fructose and incubated under continuous illumination of 200µE m⁻² s⁻¹ for 12 h under anaerobic condition. this rate was higher than that observed in the model organisms Anabaena PCC 7120, Nostoc punctiforme ATCC 29133 and Synechocystis PCC 6803. This higher production was likely caused by higher nitrogenase and bidirectional hydrogenase activities. Light and fructose were found to induce activity of nitrogenase. A study of sugar uptake by A. siamensis TISTR 8012 showed that fructose was taken up by cells more than other sugars tested. However, The production of H₂ did not increase after 12 h of light incubation which was probably due to an increased uptake hydrogenase activity, indicating that a proper adjustment of light conditions such as intensity and duration is important to minimize both the photodamage of the cells and the uptake hydrogenase activity. Nevertheless, the main obstacle for high H₂ production by A. siamensis is H₂ consumption by uptake hydrogenase under light condition. To overcome this, we created the hydrogen uptake deficient mutant by interrupting the hypS gene with antibiotic resistance cassette. We could demonstrate that the mutant strain produced about 3-folds more H₂ than wild type strain. Moreover, The ∆hupS mutant could sustain H₂ production under light exposure for long period with about 2-folds higher activity of nitrogenase when compared to wild type. Gene expression analysis by RT-PCR showed that more electrons and ATP molecules required for H₂ production in ∆hupS mutant may be obtained from the electron transport chain associated with the photosynthetic oxidation of water in PSII in vegetative cells. The results obtained from this study indicated that A. siamensis TISTR 8012 has a high potential for H₂ production leading to further development for the production of biohydrogen in an expanded scale, thus serving as a renewable and clean energy source for the future.

title: Proteomic analysis and characterization of vibrio harveyi responsive proteins in the black tiger shrimp Penaeus monodon

description: Vibriosis, caused by bacteria from the genus Vibrio, is one of the major diseases in shrimp aquaculture resulting in a high mortality and so economic losses. Here, proteomic analysis of the lymphoid organ of V. harveyi infected Penaeus monodon were performed in order to identify potential proteins responsible for the bacterial infection. A number of bacterial responsive proteins regarding antibacterial immunity and/or bacterial infection mechanism were discovered. Among the bacterial responsive proteins obtained from the proteomic screening, ATP synthase beta subunit and alpha-2-macroglobulin (A2M) exhibited considerably altered expression levels against V. harveyi infection. Hence, both of them were further characterized for their potentially necessary roles in the shrimp response to bacterial infection. Partial gene knockdown of ATP synthase beta subunit showed a high cumulative mortality of the transcript silenced shrimps and a dramatic decrease of the total circulating hemocyte numbers in the survival shrimps. We speculate that ATP synthase beta subunit is likely to serve vital roles in shrimp defense against the V. harveyi. Otherwise, the yeast two-hybrid system revealed that PmA2M’s receptor binding domain interacted with the carboxyl-terminus of transglutaminase type II, a key enzyme involved in the shrimp clotting system. In accord with this, PmA2M was found to colocalize with coagulation associated proteins on the extracellular blood clots. RNA interference-mediated knockdown of A2M transcript levels impaired the bacterial seizing ability of the shrimp clotting system, resulting in an up to 3.3-fold higher number of V. harveyi that systemically spreaded into the blood circulation at 5 min post-infection before later elimination by the immune system. A characteristic of PmA2M depleted clots in the presence of V. harveyi obviously illustrated fibrinolysis areas surrounding the bacteria. In vitro observation of V. harveyi entrapping normal shrimp clots; nevertheless, disclosed that the bacterial cells were initially immobilized firmly, but later, they can continue to proliferate and escape when the clots were digested by fibrinolytic enzymes. Additionally, V. harveyi secreted enzymes responsible for the clot lysis were further identified. The fibrinolytic activity of bacterial conditioned media was completely inhibited when adding 1,10 phenanthroline and AEBSF as well as the number of motile bacteria entrapped in the clots was significantly diminished when supplemented with AEBSF. This suggests that both metallo-proteases and serine proteases released from the bacteria are required for substantial fibrinolysis.

title: Domestic Tourist Gaze at a Post-conflict destination

description: The tourist gaze notion needs much scholarly attention to globalize. Urry (2002) himself states that tourist gaze is subject to personal experience and is highly influenced by political, religious and socio-cultural changes of the society. However, the Asian tourist gaze and domestic tourist gaze have long been missed in the tourist gaze literature. This becomes more interesting to explore in a post-conflict setting. To fill this gap in the literature, we employ TripAdvisor.com reviews. The reviews made by local tourists in English during July 2018 - December 2018 have been collected for data analysis. Thematic analysis has been employed to analyze the data.

title: Transition from domestic competition to strategic choice and its cultural effects as an ex-ante process toward international competitiveness of Thai firms: a laboratory experiments study

description: It is almost a truism that firms those strategize market-based strategies are potentially more successful than firms those do not. In the global space, non market-based strategies cannot be created or exploited easily, especially by firms from developing economies. Hence, the incentive for firms to strategize their market-based strategies instead of implementing non market-based strategies is necessary for their international success. This study adopted laboratory experiment to explore the process of strategizing incentive creation through increasing level of competition. This study answers two important claims. Firstly, more intensive policy leads to more competitive market. Secondly, more competitive market leads to more competition level of market-based strategy implementation. The experimental result supports these two claims. By confirming this ex-ante process of competitiveness creation, it serves as the confirmatory study of the argument that firms will be incentivized to create and exploit their competitive advantage by a competition in domestic market. Furthermore, the mechanism is also affected significantly by collectivism-individualism cultural dimension. This cultural effect is also confirmed by the experimental result.

title: Improved methacrylate base polymer properties in dentistry using alumina

description: The first objective of this study was to clarify the effects of silane coupling agents and different polarity solutions on bonding between poly (methylmethacrylate) (PMMA) on alumina plate with thermocyclings challenge. The second objective was to evaluate the effects of 3-methacryloxypropyltrimethoxysilane on flexural properties, fracture toughness, wear resistance and color change of alumina reinforced poly (methylmethacrylate) (PMMA) denture base. In part 1, three silane coupling agents [3-methacryloxypropyltrimethoxysilane (MPS), 3-aminopropyltriethoxysilane (APS) and N-2 (aminoethyl) 3-aminopropyltriethoxysilane (AAPS)] and 3 different polarity solutions, 70% ethanol solution, isopropanol and toluene, were selected for silanization. The shear bond strengths were statistically compared with Tukey HSD (α =0.05). The bond strengths of PMMA on the alumina before thermocyclings were greater with MPS (15.0 MPa), APS (13.8 MPa) in ethanol solution. In part 2, the 10, 30, 50 mass% of alumina filler silanized with 0, 0.1, 0.2 and 0.4 mass% of MPS was blended with heat-polymerized PMMA. PMMA without alumina filler was served as control. Bar-shaped and square-shaped specimens were prepared for flexural properties, fracture toughness and wear resistance test, respectively (n = 10). Flexural properties and fracture toughness were determined using a 3-point bending test and volume losses were measured an in-vitro 2-body wear-testing. The flexural properties, fracture toughness and volume loss were analyzed by 2-way ANOVA and Tamhane’s test (α =0.05). Flexural strength ranged from 95.1 to 115.8 MPa, fracture toughness were increase when increase amount of alumina, while volume loss ranged from 0.038 to and 0.160 mm3. In 10 mass% of alumina reinforced into PMMA, the statistic analysis showed that the 0.1 mass% of silanized group was significantly higher in flexural strength and lower in volume loss than no filler and non-silanized group. In part 3, the pink and clear PMMA silanized with 0.0, 0.1, 0.2, 0.4 mass% of MPS were evaluated the opacity and color change. The opacities value of the No filler in both of the pink and clear were significantly lower than the filler reinforced groups.

title: Dendritic polyelectrolyte fluorophores with n-aryl carbazole core

description: Novel dendritric fluorophores are designed and synthesized using N-phenyl carbazole as the core and benzoate, salicylate, or quaternaryammonium as the pheripheral groups. The synthesis relies on Sonogashira couplings between the core and ethynyl benzenes with different substituents. Upon conversion of the peripheries into carboxylate or trimethylammonium groups, water-soluble fluorophores with quantum efficiencies greater than their triphenylamine-cored analogs are obtained. This improved quantum yields results from the enhanced structural rigidity, which decreases the geometrical relaxation of the excited molecules. However, this quantum efficiency improvement approach is more apparent in the case where the molecule is lack of the internal charge transfer phenomenon. In addition, it is found that the fluorescent signal of fluorophore with salicylate group can be selectively quenched by copper (II) ion. The non-linear relationship between fluorescent intensity and concentration of copper (II) ion reveals a turn-off fluorescent switching property for the copper (II) ion at 4 micromolar and above. The fractional investigation of this fluorophore indicates that the ethynyl salicylate group attached on the phenyl ring of the core is responsible for fluorogenic response towards copper (II) ion, where as the other parts of molecule function as fluorescent signal amplification units.

title: Taxonomy of webspinners (insecta : embiidina) in western Thailand

description: Webspinners are small insects order Embiidina or Embioptera with tropical and subtropical distribution. They produce the fine silk in gland situation in the swollen foretarsi and live gregariously within silk galleries. They primarily graze on the outer bark of tree, decomposing leaf litter, mosses and lichens. The biodiversity, taxonomic position of webspinners in Thailand are poorly known. Therefore, the aims of this research were to study taxonomy, the species diversity as well as the distribution of webspinners from different habitat types in western Thailand. All specimens were identified based on morphological characters. A total of ten species and seven morphospecies from seven genera under four families of webspinners were recorded. The family Oligotomidae contained the greatest number of species (10) whereas the dominant genus found in this research was Ptilocerembia (4 species) of Notoligotomidae. There are two morphospecies of Embiidae: Oedembia sp.1 and Oedembia sp. 2, four morphospecies of Notoligotomidae: Ptilocerembia sp.1, Ptilocerembia sp.2, Ptilocerembia sp.3 and Ptilocerembia sp.4, ten species of Oligotomidae: Aposthonia borneensis, A. ceylonica, A. problita, Eosembia auripecta, E. lamunae, E. paradorni, Lobosembia mandibulata, Oligotoma humbertiana, O. nigra and O. saundersii, and one morphospecies of Teratembiidae (Oligembia sp.1). Three species of Oligotoma were recorded for the first time and three new species; Aposthonia problita, Eosembia lamunae and E. paradorni were discovered. In addition, the dichotomous and pictorial keys to families, genera and species levels and description of the webspinners from this study are presented, especially the keys to Thai webspinners based on adult females are provided for rapid observation in the field study or in the laboratory examination. Of all studied habitat characteristic types, the highest number of species (6) occurred in dry evergreen forests, mixed deciduous forests and forest parks, whereas the lowest numbers of species (1) occurred in beach forests and coniferous plantations. Three species of the Oligotoma were found only in human exploited areas, particularly in forest parks throughout the study areas, which suggested they might have been introduced to the areas. On the other hand, Eosembia lamunae, Lobosembia mandibulata, Oedembia sp.2, Oligembia sp.1 and Ptilocerembia sp.2 were found solely in natural forests. It might be expected that these species may inhabit restricted habitats having specific requirements within these forests. Moreover, the most common species, which was distributed throughout the western Thailand, was Eosembia auripecta and was able to be encountered in both human exploited areas and natural forests.

title: Comparative Study of three remineralizing products on changing the Enamel white spot lesion in vitro

description: Objective: To compare optical appearance of white spot lesion before and after intervention with three remineralizing products and determine which one has the highest potency by using computerized image analysis. Materials and methods: Ninety human tooth crowns were coated with an acid resistant varnish, leaving a small window of sound enamel parallel to the horizontal plane. Artificial white spot lesion was created by thirty minutes immersion in demineralizing solution. Samples were randomly allocated into 3 groups : group A (GC tooth mousse : Casein Phosphopeptide - Amorphous Calcium Phosphate), group B (Clinpro tooth crème : 0.21% w/w sodium fluoride anti-cavity paste with tri-calcium phosphate) and group C (Prevident : 1.1% w/v Sodium Fluoride) are subjected to 60 remin/demin cycles. Photographs of each sample before and after intervention were taken at fifteen degree angle to the enamel surface and analyzed using computerized image analysis. Data was measured in term of LI% (luminance intensity proportionality) for optical appearance measurement. Results: Paired t-test showed that LI% before and after intervention of three groups were significantly different (p&lt;0.001) at 99% confidence level. One-way ANOVA and Bonferroni statistics showed that changed LI% comparing between group A/ group C and group B/ group C were significantly different (p&lt;0.050) while group A/ group B was not significantly different (p=1.000) at 95% confidence level. Conclusion: Optical appearance of white spot lesion was decreased after applied three remineralizing products and group C (Prevident : 1.1% w/v Sodium Fluoride) represented the highest change on white spot lesion.
