title: Development and validation of a disease-specific health-related quality of life measure for thai adolescients with systemic lupus erythematosus

description: Objectives:To develop a Quality of Life Measure for Adolescent with Lupus (QoLMEAL), a disease-specific QOL instrument, for individual patient evaluation in Thai adolescents aged 10-18 years with SLE. Methods: The items were generated after an extensive review of the existing childhood SLE and HRQOL literature and HRQOL measures as well as the expert panel discussion. The revision of items comprising QoLMEAL was performed after the pre-testing in 30 adolescents and parents. QoLMEAL has parallel adolescent and parent reports with a 5-scale for responses. Field-testing proceeds at four collaborating medical centers in Bangkok. Assigned physicians assessed SLE activity and damage. Results: 128 adolescents with SLE and 123 parents participated. A total of 66 items and 8 domains covering physical health, daily activity, family, treatment, emotional health, social, schooling, and finance were identified. QoLMEAL has acceptable content, convergent, and discriminant validity. A Cronbach’s coefficient alpha of QoLMEAL is 0.94. Moderate correlation was found between adolescent and parent reports (r=0.62, P &lt; 0.01). Physical health, daily activity, and treatment domains have small correlation with lupus activity or no correlation with damage indices. Conclusion: The QoLMEAL is a validated SLE-specific HRQOL instrument with 66 items across 8 domains for use in SLE adolescents in Thailand.

title: Effects of dental radiation on the expression of apoptotic-related gene in primary human bone cells

description: Exposure to 1 milligray ionizing radiation could induce DNA lesions probably leading to cell death through apoptotic process. Thus, performing dental radiography in a milligray range might be dangerous to human bone cells. The purpose of this study was to investigate the effects of dental radiation on the expression of apoptotic-related gene in primary human bone cells. Human bone cells were grown in 15% DMEM and irradiated with 0, 1, 2 doses of a periapical radiograph. The cytotoxicity of irradiation was investigated by MTT assay after 24 hours. The level of apoptotic-related gene expression (Bcl-2, Bax, Bad, Bcl-XL, Caspase-3) was analyzed by RT-PCR assay, four hours post irradiation No cytotoxicity was observed at 24 hours after dental irradiation. Interestingly, most of the results demonstrated a decrease of apoptotic-related gene expression at 4 hours after dental irradiation. Only Bax and Caspase-3 were significantly decreased compared to the control. In conclusion, dental radiation affects apoptotic-related gene expression. Therefore, prescribing dental radiograph should be highly selective and the principle of ALARA (As Low As Reasonably Achievable) should be followed.

title: Effects of promoters on biomas gasification using nickel

description: This research studied the preparation of Ni catalyst on dolomite support. The performance of an addition of catalyst was evaluated on the steam gasification of coconut shell and palm shell to produce syngas. The effects of parameters, such as calcination temperature, reaction temperature, steam per carbon (S/C) ratio, oxygen flow rate, and types of promoters, were investigated with the purpose of optimizing the gaseous products. The experimental works showed that Ni/Dolomite catalyst efficiently enhanced the refoming reaction and tar cracking. Futhermore, it was found that gaseous products were highly produced at temperature of 800 degrees celsius and (S/C) ratio of 0.95 At this condition, small amount of tar was found. Carbon conversion to gaseous products of coconut shell and palm shell were 81.25% and 78%, respectively. The effects of the types of promoters, such as Platinum, Cobolt, and Iron, on biomass gasification were also evaluated. The areas of interest were the effects of preparation methods which were impregnation and coprecipitation. It was found that catalyst preparation by impregnation method gave superior performance. The conclusion can be drawn from experiments that platinum promoter enhanced refoming reaction, iron promoted water gas shift reaction, and cobolt promoter favored methanation reaction. The addition of metal reduced cafbon deposition on Ni/Dolomite.

title: Landslide hazard investigation in Changwat Nan

description: The Nan province in northern Thailand was selected for landslide hazard investigation because there was a series of landslides in August 23, 2006 that damaged properties and lives. The investigation is aimed to evaluate the susceptibility or hazard mapping of landslides in the Nan study area using remote-sensing interpretation and geographic information system (GIS). Landslide locations or scars were identified in the Nan study area from interpretation of aerial photographs as well as enhanced Landsat 7 ETM and IKONOS image for constructing the scar map. Then several factors affecting landslides, including elevation, slope, landuse, lineaments and lithology were identified and displayed as maps using GIS. Later, landslide assessment was done using bivariate probability method and followed by weighting analyses of involving factors. The results indicates that the open-forest areas dominated by the steep slopes, sandstones / tuffaceous rocks, proximal long faults / fractures, are prone to landslide hazard. Subsequently, degrees of landslide hazards were expressed as very low to very high hazard levels. The result is shown as a landslide hazard map with a satisfactory cross validation agreement. The outcome map also indicates that high- to very high- level hazard areas are the mountainous areas in Chalerm Prakiat, Song Khwae, Chiang Klang and Pua Districts. Several districts, such as Na Noi, Wiang Sa and Nan in the southern part of the Nan study area have much lower hazard level.

title: Long-term antiepileptic drug effect on bone destiny in Thai pre-menopausal epileptic patiens comparing with aged matched healthy controls

description: Objectives: To study whether there is significant adverse effect of long-term antiepileptic drug (AED) therapy on bone mineral density (BMD) in Thai ambulatory pre-menopausal epileptic patients in comparison with age range-matched healthy Thai pre-menopausal females. Design: cross sectional, analytical, observational study. Setting: Epilepsy Clinic at Siriraj Hospital, a tertiary care and training center Research Methodology: All pre-menopausal epileptic female patients aged 20-50 years receiving AEDs ≥ 3 years and age matched pre-menopausal healthy female were interviewed with a case record form according to inclusion and exclusion criteria as well as baseline characteristics. All eligible participants had physical exam, blood tests, urine exam and BMD measurement. Baseline characteristics and BMD of finally included patients and controls were then analyzed and compared. Results: 50 from eligible 57 epileptic patients and 51 from 63 participated controls were included. BMD at femur neck was significantly lower in patients with p=0.064, 95% CI -0.02 – 0.69. BMD at other sites, i.e. L 2-4, femur trochanter, femur total and radius 33% tended to lower in patient group. Proportion of osteopenia plus osteoporosis at L 2-4 and femur neck were significantly higher in patients, p = 0.014 and p = &lt; 0.001 respectively. There was a trend of higher osteopenia-osteoporosis in patients at femur trochanter, femur total, radius UD, and radius 33% Conclusion: The study proved that AEDs had adverse effect on BMD resulting in decreased BMD after receiving ≥ 3 years in Thai pre-menopausal epileptic female patients who had no other disorders or drugs with BMD decreasing effect.

title: Mechanical properties of polypropylene composites reinforced by organoclays and glass fibers

description: In this study, isotactic-polypropylene (iPP) composites reinforced with an organoclay were prepared by a twin-screw extruder by blending iPP with clay that modified with an amine surfactant. The use of surfactant caused the layered silicate of organoclay in iPP/organoclay nanocomposites to move further apart. After that iPP/organoclay nanocomposites were then blended with iPP that had been reinforced with glass fibers using the twin-screw extruder in various blend ratios. The iPP/glass fibers /organoclay nanocomposites were then characterized for their morphology and various properties, thermal and mechanical integrity. X-ray diffraction (XRD) analysis indicated that the silicate layers of the organoclay in the nanocomposites were more ordered than those of the original organoclay, which was confirmed by transmission electron microscopy (TEM). The iPP/organoclay nanocomposites showed greater content of β-crystalline phase, increased degree of crystallinity, and increased crystallization temperature than the iPP/glass fibers composites, which was confirmed by both XRD and differential scanning calorimetry (DSC) results. With regards to the mechanical properties, iPP/organoclay nanocomposites exhibited lower stiffness than iPP/glass fibers composites. Interestingly, the iPP/glass fibers/organoclay nanocomposites exhibited much improved stiffness than both of the iPP/organoclay nanocomposites and the iPP/glass fibers composites.

title: Medical students' attitudes and behaviours regarding academic misconduct

description: Objectives: To determine attitude and self reported behavior in medical students to scenarios involving academic misconduct and the association between medical students’ attitudes and reported behaviors involving academic misconduct and gender, academic years, cumulative grade point average (GPAX), and campus. Methods: In academic year 2008, a cross-sectional study using an anonymous, self-administered questionnaire was conducted in Faculty of Medicine, Chulalongkorn University. All medical students were recruited. Completed questionnaire were collected and analyzed. Results: Of the 1217 medical students (81.5%) who completed the questionnaire, the majority of medical students felt that most behaviors in the scenarios were wrong and admitted engaging is such behaviors. Six hundred sixty three (55.0%) students responded that they should inform faculty of another students’ academic misconduct, but only 126 (10.4%) students stated that they had or would consider reporting it. Being male was the only factor that was associated with poorer attitudes. For behavior, all factors were associated with misconduct behavior. After multivariate analysis, gender (male &gt; others) were the three factors that revealed significant links to misconduct behavior. Conclusion: The majority of medical students considered academic misconduct to be wrong and would not engage in it. However, many of them admitted engaging in such behaviors. There was an association between gender and students’ attitudes, while their behaviors were associated with gender, academic year, and campus.

title: MRI-based anthropometric measurements of proximal humerus in Thai population and correlation to the shoulder prostheses

description: All anatomical data of the proximal humerus measured from the 3D reconstruction of the MRI of patient shoulders who performed MRI between Jan 2008 – Dec 2008. We used CATIA to measure all parameters and minimize the human error by using a computer to calculate a 3D model. The mean of total diameters of articular was 36.64±4.44 mm. The mean of male and female shoulders were 40.83±1.36 mm., 33.57±2.76 mm. respectively. Therefore, the difference between gender was significant. The mean articular thickness of total subjects was 15.48±2.38 mm. Consisting of the mean of male ; 16.83±2.05 mm., and the mean of female ; 14.50±2.13 mm. The difference of articular thickness between gender was also significant. The mean neck-shaft angle of all subjects was 137.71±6.43 mm. Separately, that the mean of male and female subjects were 138.80±4.86 mm., 136.92±7.32 mm. respectively. The mean medial offset of all subjects was 5.43±1.51 mm. It explained that the mean of male and female subjects were 5.29±1.81 mm., 5.53±1.26 mm. respectively. The mean posterior offset of all subjects was 1.15±0.94 mm. We considered about the mean of male and female subjects were 1.27±0.80 mm., 1.06±1.04 mm. respectively. The mean of all retroversion angles was 13.99±16.17 mm. The mean of male and female subjects were 10.21±16.16 mm., 16.76±15.82 mm. respectively. Subsequently, the difference of neck-shaft angle, medial offset, posterior offset and retroversion angle between gender were not significant. All data of this study when we compared to the previous in western population, we founded significant difference in diameter of articular, neck-shaft angle, medial offset and posterior offset. The diameter of articular and articular thickness were compared to the same parameters of the currently used shoulder prosthesis ( Zimmer, Johnson ). We recommended to use currently shoulder prosthesis in Thai male population that diameter more than 40 mm. and did not recommend to use in any Thai female population. In Thai male population, the Zimmer prosthesis was more suitable size to use because of the availability of the articular thickness with the same diameter. This finding showed that a implant component suitable for using in Western population may not be compatible for Thai population. The results of the project could provide fundamental data for the future design of shoulder prostheses suitable for the Thai population.

title: mRNA expression of TNF-a (Alpha), IL-10, TGF-B (Beta), IP-10 and LiplL32 in kidney and liver of hamsters infected with pathogenic leptospira

description: Leptospirosis is a worldwide zoonosis caused by spirochetes of the genus Leptospira. The spectrum of human disease caused by leptospires is extremely wide, ranging from sub-clinical infection to a severe syndrome of multi-organ infection with high mortality. Leptospirosis pathogenesis mechanisms are not clearly understood. Various enzymes and toxins have been identified and suggested to be involved in tissue damage. In addition, it has been demonstrated that immune response to Leptospira may induce pathologies in infected organs. Cytokine and chemokine induction by Leptospira or Leptospira components have been demonstrated. Various Leptospira components have been studied; however, the most widely studied components are outer membrane proteins, especially LipL32. Most studies on cytokine induction by Leptospira were done in vitro. In this study, the expression of mRNA of TNF-α, TGF-β, Il-10 and IP-10 in kidneys and livers, the commonly affected organs in Leptospirosis were investigated. Leptospira interrogans serovar Pyrogenes was intraperitoneally injected into Golden Syrian Hamsters. Kidney and liver tissues were collected at 3, 5 and 7 days after injection. RNA was extracted from tissues for RT-PCR to demonstrate cytokine/chemokine expression. The expression of LipL32 in kidneys and livers was also investigated since it has been demonstrated that this protein induced cytokine/chemokine expression. This study demonstrated that LipL32 was expressed in both kidneys and livers of infected hamsters. The level of LipL32 expression was similar in both tissues. However, the pattern of cytokine mRNA expression was different. IL-10 and IP-10 expression was induced in kidneys whereas they were undetectable in livers. TNF-α and TGF-β expression was enhanced in livers from infected hamsters. Further studies such as localization of cytokine expression in order to demonstrate the correlation with pathologies in kidneys and livers and the study of expression of other Leptospira components will provide further information not only on the immune response to Leptospira but also on pathogenesis of this infectious disease.

title: Natural rubber / nitrile rubber blends compatibilized by graft copolymer of styrene and acrylonitrile onto natural rubber

description: Natural rubber (NR) has excellent mechanical properties, but has the relatively poor oil resistance which is opposite to nitrile rubber (NBR). Thus, the direct blending of these two rubbers is expected as the solution to enhance the mechanical properties and oil resistance of the blends. However, the mechanical performance of this blends are poor due to the incompatibility caused by difference polarity between these rubbers. Therefore, the modification of NR structure via graft copolymerization of acrylonitrile (ACN) and styrene (ST) onto NR for using as the compatibilizer in NR/NBR blends was the aim of this work. The graft copolymerization was carried out by both of solution method using benzoyl peroxide (BPO) or 2,2́ azoisobutyronitrile (AIBN) as initiators and emulsion method initiated by potassium persulfate (K2S2O8) or cumene hydroperoxide /tetraethylene pentamine; CHPO/TEPA). The influence of reaction parameters: the initiator concentration, reaction temperature and nitrogen pressure was investigated. The structure of grafted copolymer on NR structure was analyzed by spectroscopic techniques. It was found that the optimum condition for preparing the graft NR was carried out by the solution graft copolymerization using wt ratio of ACN/ST 3/1 initiated by 5 parts by weight of BPO at 70°C under 2 bar of nitrogen pressure for 6 h to achieve the maximum percentage of graft copolymer as 85.0%. The graft NR product (GNR) was used as a compatibillizer for NR/NBR blends. The results indicated that the increase in the GNR content in the blends improved the mechanical properties and oil resistance of NR/NBR vulcanizates. The tensile fracture surfaces of NR/NBR blends examined by scanning electron microscope (SEM) showed the better interfacial adhesion between two rubber phases after addition of GNR in the blends.
