Abstract: In this study, the gene expression profile of Cfs in comparison to Lfs was performed using oligonucleotide microarrays. The common- and unique-expressed genes in Cfs and the promising roles in cancer promotion and progression were determined. PN was markedly over-expressed in Cfs confirmed by real time RT-PCR and western blot analysis. Immunohistochemistry examination of a number of patients with intrahepatic CCA showed the expression of PN solely in stromal fibroblasts, but was expressed neither in cancer cells nor immune cells. Low to no expression of PN was observed in tissues of benign liver disease and hepatocellular carcinoma. CCA patients with high levels of PN had significantly shorter survival time than those with low levels (P = 0.026). Multivariate analysis revealed high levels of PN (P = 0.045) and presence of lymph node metastasis (P = 0.002) as independent poor prognostic factors. The in vitro study revealed that recombinant PN induced CCA cell proliferation and invasion. Interestingly, interference RNA against integrin α5 significantly reduced the cellular response to PN-stimulated proliferation and invasion.The gene expression profile of fibroblasts in CCA is apparently explored for the first time and has determined the genes involving in induction of this cancer progression. High PN can be used to distinguish CCA from other related liver diseases and is proposed as a prognostic factor of poor survival. Regulation of fibroblast-derived PN in CCA proliferation and invasion may be considered as an alternative therapeutic approach.Cholangiocarcinoma (CCA) originates from biliary epithelial cells and is a unique cancer in northeastern Thailand where the prevalence of a liver fluke, Opisthorchis viverrini infection is higher than elsewhere in the country. A recent study showed a strong positive correlation of CCA incidence and the prevalence of O. viverrini infection [1]. In other countries, CCA has been shown to correlate with Clonorchis sinesis [2,3], a

Abstract: Crop is commonly grown in intercrop combinations of which cereal/legumes are the most widespread in tropical countries. The availability of low light inten-sity due to shading is the critical factor in determin-ing legume yield in intercropping. The experiment searches of better soybean cultivar for intercropping. A field experiment was conducted at the experimen-tal farm of Khon Kaen University in 2005. The objec-tives of this study were to determine the influence of light regimes (30% of normal light, 50% of normal light and normal light) on the growth and yield of four soybean cultivars (early, medium and late ma-turity) under artificial shading at 35 days after seed-ing until harvest in the wet and dry seasons. The re-sults showed that grain yield was significantly (p<0.05) decreased under the low light intensity at 30% of natural light both in wet and dry season. This was mainly due to low light intensity at 30% of natural light decreasing the number of pods per plant in the dry season. For cultivars, grain yield was sig-nificantly difference (p<0.05) among cultivars both in the wet and dry seasons. The cultivar KKU 74 (me-dium maturity) gave maximum grain yield both in wet and dry season under the low light at 30% of natural light. The KKU74 cultivar is better adapted to shading environment than other cultivars. This was due to the KKU74 cultivar produced higher chlorophyll b concentration in leaves after the plant experienced to shading. This physiological character can be used for soybean breeding program in shading tolerance. Therefore, the cultivar KKU 74 had a higher potential yield advantage in intercropping systems in which low light intensity is a major limit-ing factor on grain yield.

World Journal of Orthopedics , 2012, DOI: 10.5312/wjo.v3.i1.5
Abstract: AIM: To evaluate the association between various risk factors, including sleeping position, and impingement syndrome. Impingement syndrome is the most common cause of shoulder problems. The pathogenesis of this problem is still debated these days. METHODS: This was a case control study conducted at the outpatient clinic of Songklanakarind hospital. Data regarding history, physical examination and radiographic evaluations using supraspinatous outlet views were obtained from all patients with clinically suspected impingement syndrome. The diagnoses of impingement syndrome were confirmed by a xylocaine subacromial injection test. All patients were interviewed concerning their usual sleeping position, which was categorized into supine, decubitus, prone and undetermined. Radiographs were evaluated to determine the shape of the acromion, which was divided into 3 types: flat, curved and hook. We used logistic regression analysis to determine the association between risk factors and outcome. RESULTS: The study group included 111 patients with impingement syndrome and 191 healthy volunteers as a control group. The mean age was about 50 years with a body mass index (BMI) of 24 kg/m2 in both groups. The most common shape of the acromion was flat (84.5%), followed by curved (10.7%) and hook (4.8%). We found the 4 independent risk factors affecting impingement syndrome were smoking status, occupation, acromion shape and sleeping position. Patients who currently smoked had a 6.8 times greater risk of impingement syndrome compared to non-smokers (OR 6.8, 95% CI: 1.2-39) and government officers had a 6.3 times increased risk compared to rubber tappers (OR 6.3, 95% CI: 1.3-30.3). Patients with a hook type acromion had 6.2 times the risk of flat type (OR 6.2, 95% CI: 1.1-35) and patients who slept in the decubitus position had 3.7 times the risk of those who slept in the supine position (OR 3.7, 95% CI: 1.2-11.6). No significant associations were found between age, sex, BMI, sports activity and impingement syndrome. CONCLUSION: Independent risk factors affecting impingement syndrome are current smoker, government officer, a hook-type acromion and the decubitus sleeping position.

Abstract: Visual inspection is a crucial process in industrial quality control. Visual inspection primarily relies on the inspector s performance which can be influenced by many factors. The purpose of this study is to identify, the most suitable search pattern and training pattern for visual inspection of a 3D simulation model. The program was set to create a 3D task to measure the visual inspection search patterns. The sampling group was screened for performance and efficiency, 48 students were selected for the experiment and were divided into two groups a systematic rotation pattern group and a free rotation pattern group, respectively. The results showed that the search pattern that produced the best performance from the inspector for visual inspection of a 3D simulation model was systematic horizontal search with systematic rotation.

Abstract: The new composite of compressed fiberboards with free urea-formaldehyde production from durian fiber composite with latex binder were investigated. The objective of this study is to evaluate the quality of compressed fiberboards bond with durian fiber and latex binder. In this experiment, compressed fiberboards were produced from durian fiber with latex (3:1), silica (30%), azadirachtin (40%) and Alkyl Ketene Dimmer (AKD, 4%) composites. The influence of AKD in reducing water absorption was investigated by varying ratio 0, 2, 3, 4 and 5% while varying titanium dioxide to lacquer ratio from 0, 0.2, 0.3 and 0.4% was studied to improve the mechanical property. Their composite materials were carried out from hot compression molding and examined the mechanical properties following JIS A5905-1994 and ASTM standard. The properties of the resulting mixed latex-fiber-silica azadirachtin and AKD were evaluated and compared with MDF. The new compressed fiberboards showed the good application material for energy conservation, environmental friendly and commercial market.

Abstract: biochar can improve soil structure and water retention, enhance nutrient availability and retention, ameliorate acidity, and reduce heavy metal toxicity to plant roots. in this study, a basin experiment was conducted to investigate the effects of quail litter biochar (qlb) on the availability of cd to physic nut (jatropha curcas l.) plants. qlb was applied to the soil in which four new physic nut varieties (takfa, doi saket, lao, and rayong) in factorial combinations at four levels (0, 5, 10, and 15 g kg-1 soil) to soil that contained 60.8 mg cd kg-1. after transplanting plant height and canopy radius were measured every 2-mo and the number of leaves and branches at 6-mo, while yield components and cd residues were measured at 8-mo intervals. the contaminated soil was analyzed for chemical characteristics, nutrients, and cd residue after the plant harvest. the addition of qlb to soil caused a significant increase in the soil's growth potential and physic nut yield components (p < 0.05), a significant decrease in the cd residue in the plant (p < 0.05), and a significant increase in the chemical characteristics, nutrients, and cd residue in soil (p < 0.05). in conclusion, qlb application can significantly decrease the bioavailability of cd to physic nut plants, increase plant growth potential and yield, and has potential to remediate cd-contaminated soil. however, qlb levels higher than 15 g kg-1 soil mixture were not advisable because qlb is alkaline in nature, and this can affect soil ph.

Abstract: This study purposes to find a practical method to increase the number of sugar-palm (Tao) trees and restore thecommunity forest in northern Thailand. The experiments dealt with three aspects of sugar-palm seedlings. These were: 1) tofind the most efficient method of propagation, 2) to search for the best way for separation and transplantation, and 3) to findthe best growth promoter. This project was conducted from October 2005 to June 2007 at San Charoen Village, Pha ThongCommunity, Tha Wang Pha District, Nan Province. The results were as follows: Firstly, trimming both ends of 36-month-oldsugar-palm seeds provided the shortest period of germination. As a side benefit, it was easier to peel the seeds out of thefruit. Secondly, the most efficient way of separating seedlings was transplanting them immediately with their one leaf cuttwo-thirds off. Spraying with water every two hours during the first week guaranteed 82 percent of survival of the seedlings.Lastly, 15-15-15, 13-13-21 and 46-0-0 fertilizer formulations promoted the growth of one- to three-year sugar-palm seedlings.These seedlings produced more new green emerging leaves than the unfertilized plant. However, when economics areconsidered, the non-fertilizer application gave a better net benefit than the three fertilizer formulations. Therefore, we recommendthat the sugar-palm be planted in community forests in northern Thailand using plenty of water, with a propertillage practice, and without costly fertilizer. We also imply that farmers will be more confident in restoring their sugar-palmforests using this technique because they have an active role in the research project.
