title: Biologic responses of rice field crab Esanthelphusa nani (Naiyanetr, 1984) to herbicides in paddy fields, Nan province

description: Nowadays, herbicides have been widely used with increasing intensity in Nan Province. Since herbicides may pose adverse effects on non-target organism, it is crucial to monitor herbicide contamination and potential health hazards to animal living in agricultural area. Environmental screening with chromatographic techniques showed that detectable level of atrazine was found in water of the herbicide utilization area. In addition, a rice field crab Esanthelphusa nani was selected as a sentinel species for herbicide contamination and related biologic responses. Crabs were collected from two study sites: a reference site where no herbicides were used and a contaminated site where herbicides were used routinely. Crabs were subjected to analyses for herbicide contamination, changes in detoxifying enzyme activity, lipid peroxidation and morphometric and gravimetric analyses. Herbicide residue analysis showed that detectable levels of atrazine, glyphosate and paraquat was found in the crab tissue, with significant site-related difference in level of atrazine. Activities of hepatopancreas glutathione S-transferase (GST), a crucial detoxifying enzyme, of both male and female crabs were significantly elevated in the contaminated site compared to the reference site crabs. Although level of lipid peroxidation, an indicative of cell damage, was not significantly different between sites, it strongly correlated with levels of GST and atrazine in the crab. Relative body weight of male crabs in the contaminated site was significantly lower than those from the reference site. Sexually dimorphic traits of the crab including abdominal area and major claw size of male crabs from the contaminated site were also significantly smaller compared to those of the reference site animals. Correlation analysis indicated that atrazine in crab tissue was associated with decreased major claw size as well as increased hepatopancreas GST activity and LPO levels of crabs in the contaminated area. The results of this sentinel study could be used for assessing a potential impact of herbicide contamination on non-target organisms in agricultural environment.

title: Development of amperometric technique to detect antioxidant capacity in serum

description: A simple and rapid amperometric method using screen-print carbon paste electrode (SCPE) and bias potential at 0.15V, was developed to determine the antioxidant capacity in serum. The 2,2’-azobis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) was used as a free radical generator. ABTS•+ (ABTS cation radical) was generated from the reaction between ABTS and potassium persulfate (K2S2O8) at a molar ratio of 1: 0.25. The radical was stable at least 3 days when stored at 4⁰C in the dark. The developed method was used to determine antioxidant capacity in human serum. The reaction of ABTS•+ with antioxidant sample was measured, having Trolox as the standard antioxidant. After reaction between ABTS•+ and antioxidant sample, the residual ABTS•+ was measured for 100 seconds. The relationship between Trolox concentration and current signal was linear at the concentration range of 0-100 M. SCPE could be used at least thirty times with %RSD of 4.9%. This developed method was successfully used for determining antioxidant capacity of Thai normal subjects and patients. The average antioxidant capacity in sera of normal subjects and patients were determined to be 1486±66 and 1354±85 M TE, respectively. Moreover, the method could also be used for measuring antioxidant capacity of the spiked serum with -tocopherol.

title: Prediction of water quality for Bangkok canals using data mining techniques

description: Water is usually subject to contamination caused by human activities. The main problems being studied are two folds, 1) derivation of an appropriate model that can achieve accurate classification of water, and 2) construction of an efficient model in predicting the amount of Dissolved Oxygen (DO) that affects water quality of Bangkok's canals based on 13 water quality parameters. These parameters are collected from the data obtained from the Department of Drainage and Sewerage, Bangkok Metropolitan Administration during 2003-2011. This research proposes two prediction models. The Classification and Regression Tree (CART) model is established to classify water quality in Bangkok’s canals. The second model is set up to cluster water quality parameters and integrated the clusters to predict DO with the help of an ANN model. Result comparisons by correlation coefficient (R), mean absolute error (MAE), and mean square error (MSE) between the proposed technique and other techniques show higher accuracy than the comparative techniques. Contributions of this work can be applied to better water quality planning and effective treatment.

title: Detection of aberrant SHP-1 promoter 2 methylation, an implication in advanced non-small cell lung cancer

description: Backgroung: Under physiological conditions, leukocytes contribute to the majority of circulatng DNA in plasma. Therefore, detection of SHP-1 promoter-2 (SHP1P2) methylaton to represent epithlial tumor-derived circulatng nucleic acid may serve as a potential plasma biomarker for epithelial-derved cancer. Furthermore the fraction of caner cel-derived and inflammatory cell-derved nucleic acid was still enigmatic. Total amount of circulating nucleic acid was increased in cancer patient and it was correlated with prognostic outcome in various types of cancer. These might be the effect of tumor-derved nucleic acid, correlated with tumor burden; however the interaction of cancer and immune cell was not negligent. Materials and method: A dual hybridization probe and real-time quantitative PCR-based assay was used to determine the level of SHP1P2 methylation in plasma. Blood samples were prospectively collected from 58 advanced NSCLC patients and 52 healthy control. Clinicopathological data and outcome of treatment were included in the anaysis. Results: The levels of SHP1P2 methylation in plasma from controls were mostly undetectable. In contrast to the NSCLC patients. SHP1P2 methylation was significantly higher than tha of controls. Pretreatment level of the SHP1P2 methylation was significant associated wth the survival. Patients who had SHP1P2 methylaton &lt; 0.7m ml-1 had better progression-free survival (5.2 vs. 2.6 months, p = 0.009) and overal survival (12.6 vs. 7.6 months, p = 0.01). SHP1P2 methylaton was the only independent predictive factor of survival by multvarate analysis. Moreover circulating DNA evel was also correlated with survival outcome however less specific than SHP1P2 methylation. The follow-up level correlated well with reponse of treatment. This influenced by the impact of tumor-derived and inflammatory cell-derived nucleic acid. Conclusion: Measurement plasma SHP1P2 methyation may serve as a potential non-invasive biomarker for the diagnosis and prognosis assessment in lung cancer patients adding to circulatng DNA level. This classification may serve as a biomarker for risk-adaptive treatment

title: Effects of phyllanthin and hypophyllanthin on vascular tension of isolated rat aorta

description: The purpose of this study was to investigate the modulating effects of phyllanthin and hypophyllanthin on vascular tension, using in the in vitro model of isolated rat aorta. The results indicated that both phyllanthin and hypophyllanthin (1-100 µM) significantly relaxed the sustained contraction induced by phenylephrine (PE) in a concentration-dependent manner. In addition, endothelial removal had no significant influence on the vasorelaxation responses of the aortic rings toward these two compounds. In endothelium-denuded rings, vasorelaxant inhibitors [atropine (1 µM), BaCl2 (10 µM), glybenclamide (10 µM), indomethacin (10 µM), L-NAME (100 µM), methylene blue (10 µM), propranolol (10 µM), 4-aminopyridine (100 µM) and TEA (10 µM)] did not inhibit the vasorelaxation responses induced by either phyllanthin or hypophyllanthin (100 µM). The data also demonstrated that the two lignans were able to induce aortic contraction which could be suppressed by either tyramine or prazosin. In addition, both compounds inhibited the PE- and KCl-mediated contraction of aortic muscle in concentration-dependent manner. Furthermore, these two compounds (100 µM) also significantly inhibited the Ca2+- induced contraction of aortic muscles that were depleted of Ca2+. However, only phyllanthin (100 µM), but not hypophyllanthin was able to inhibit the Ca2+- mediated contraction in high K+ - Ca2+- free condition. Both compounds (100 µM) significantly inhibited PE-induced contraction in Ca2+- free condition, but could not affect caffeine-induced contraction. Taken together, phyllanthin and hypophyllanthin could modulate the vascular tension via the endothelium-independent mechanisms. The modulating effect of the test compounds were likely involved with the inhibition of Ca2+ influx as well as with the inhibition of PE-mediated Ca2+ release from sarcoplasmic reticulum.

title: Mandarin speakers’ difficulties with spatial prepositions in English and their conceptualization of spatial relations

description: Previous studies claim that it is difficult for learners of English to master English prepositions. Even though pedagogical descriptions have already included fundamental uses, there are still instances showing that learners choose prepositions differently from native speakers of English. This learning gap should refer to the different systems of conceptualization by the two groups of language users. The objectives of the present study are threefold: 1) to investigate the difficulties which Mandarin Chinese learners of English encounter when choosing the spatial prepositions in English, 2) to modify the existing semantic networks for the spatial relations in English and compare them with the constructed semantic networks for Mandarin Chinese localizers, and 3) to explain the learning difficulties (in No.1) cognitively by relating them to comparisons of the semantic networks for the spatial relations in both languages (in No. 2). To fulfill the objectives, the Test of Spatial Relations (TSR) which contained sixty multiple-choice test items, were created to examine the difficulties that a sample of Mandarin Chinese learners of English encountered. A total of 73 valid test copies were collected for analyses. The semantic networks for the Mandarin Chinese localizers were created based on Sinica Corpus, and the analyses adopted Principled Polysemy developed by Tyler and Evans (2003). The TSR results confirm and define learning difficulties. The comparisons of the semantic networks in English and Mandarin Chinese suggest similarities and differences. The discussions of the TSR results and the semantic networks lead to cognitive descriptions based on contrastive analysis. The TSR results suggest that Mandarin Chinese Learners of English especially have difficulties with indicating verticality including above, at, below, in, on, over, and under, especially when they are metaphorically used. The comparisons between the semantic networks for the spatial prepositions in English and Mandarin Chinese localizers reveal that there are more differences than similarities. The analysis of the relationships between the test items and the semantic networks shows that the similarities in the spatial-physical senses are more likely to enhance ease of learning while it is more possible that the differences in the spatial-functional senses make MLEs especially confused.

title: The development of a form-focused web-based instruction to enhance the English grammatical and writing competence of Thai undergraduate sports science students

description: The study objectives were (1) to investigate the needs of Thai undergraduate sports science students and their stakeholders to enhance the students’ English grammatical competence and writing ability, (2) to develop the form-focused web-based instruction, (3) to find out the effects of the form-focused web-based instruction on the sports science students’ English grammatical competence and writing ability, and (4) to investigate the attitudes of sports science students toward the instruction. The study was descriptive and experimental research including three phases: needs analysis, course design, and evaluation of the effectiveness of the form-focused web-based instruction. The study was conducted with 83 undergraduate sports science students at Mahidol University in the 2011 academic year. During the experiment, students were assigned to do grammatical exercises on the web-based course, practice writing on the weblog, and discuss on Facebook regarding their problems in grammar and writing. Based on the gain scores of the pre-test and post-test, grammatical exercises, and writing assignments, the students had improvement in grammatical competence and writing ability. There were statistically significant differences of the mean scores of the pre-test and post-test (t = 6.07, p =.000), weblog writing assignments (F = 10.355, p = .000), and grammatical exercises: cloze tests (F = 33.142, p = .000) and the error recognition tests (F = 52.66, p = .000). The students also had positive attitudes toward the instruction. Therefore, such instruction was worth developing for and implementing with sports science students.

title: Expression profile of notch receptors in tfh cells and the effect of inhibition of notch signaling on the effector functions of tfh cells

description: Follicular helper T (Tfh) cells, a newly characterized effector T helper cell subset, are mainly found in B cell follicles of secondary lymphoid organs. Tfh cells are effector cells which provide help for antibodies production and for B cell differentiation. Tfh subset can be distinguished from other helper T cell subsets by the use of CXCR5 and ICOS expression. Notch signaling pathway is a well conserved pathway operating in various organisms and functioning in controlling many cellular processes. Previous study on gene expression in Tfh cells by microarray analysis showed that these cells expressed Notch signaling related genes. However, the expression profiles of Notch receptors and the effect of inhibition of Notch signaling on the effector functions in Tfh cells have not been studied. In this study, we investigated the expression profiles of Notch receptors and its target genes in Tfh cells isolated from human tonsils. Expression of Notch1-4 and two Notch target genes were investigated by quantitative RT-PCR. Notch1-3, DTX1 and Hes1 were expressed in Tfh cells but the expression of Notch4 was not detectable. More importantly, Notch1, Notch3 and Hes1, are found to be expressed significantly higher than the control non-Tfh population. Next, we investigated the effect of inhibition of Notch signaling on Tfh cells function using gamma secretase inhibitor (GSI). Expressions of Bcl-6, one of essential genes regulating Tfh functions were significant lower in GSI treated cells than the control. We next investigated the ability of Tfh cells subset to induce IgG secretion of B cells. We found no difference in IgG production between GSI treated Tfh and the control group. Taken together, these results strongly suggested that Notch signaling is involved in effector function of human Tfh.

title: Capacity building model for local governmental agencies on sustainable tourism development adapting to climate change

description: The lack of proper water resource management and water shortage likely caused by climate change would affect sustainable tourism development in Thailand. Local governmental agencies (LGAs) are the main body having directly role and responsibility to deal with such problem. Capacity building of the LGAs to handle water resource management and its shortage and its impacts would be beneficial not only to tourism but also to the community. The study on capacity building model for local governmental agencies on sustainable tourism development adapting to climate change was carried out at Koh Chang, Trat province, Thailand. The objectives of the study are to study the impacts of climate change on water resources affecting tourism businesses, to assess the capacity of the LGAs in addressing such the impacts, and to develop the conceptual model of capacity building for the LGAs in adapting to climate change impacts on water resources affecting sustainable tourism development on the island. Climate data between 1970 and 2009 were analyzed. Other relevant data were collected through questionnaire, interview and in-depth discussion with twenty four stakeholders in four villages of Koh Chang, namely Ban Klong Nonsri, Ban Klong Praw, Ban Bang Bao, and Ban Salak Petch. The study results found that the island has significantly increased in rainfall producing large amounts of water during rainy season (May-October) but there still has water shortage particularly during the peak period of tourism (November-February). This problem is caused by the mismatch between the time period of tourism season and rainy season. It also found that changing in rainfall and temperature patterns reduced availability of water supply. Additionally, there is no a large reservoir to storage water from short and steep water tributaries. This study also found the incapability of the LGAs in managing water resources and its shortage that of the most concern. Therefore, the conceptual model of capacity building for the LGAs is proposed by taking initial consideration on capacity building policy through approaches of human resource development and education, technology need assessment, and water management system. The LGAs need to enhance their knowledge and skills on climate change adaptation and water resource management and relevant technology. The linkages of appropriate technologies for an effective water management system are also required. The enabling capacity of the LGAs would finally sustain the development of tourism and community on Koh Chang. Therefore, it would recommend that the LGAs’ short term and long term implementing plans on capacity building on water resource management should be consistently developed. The capacity building of other stakeholders such as local community should be further studied. Furthermore, the model of capacity building of the LGAs’ on proper water management needs to be further technical study.
