SAHA syndrome is characterized by the tetrad: seborrhea, acne, hirsutism, and androgenetic alopecia. No previous study has examined the prevalence of glucose abnormalities in ovarian SAHA and explored whether it may be an independent risk factor for glucose abnormalities. In a prospective controlled study, we investigated the spectrum of glucose abnormalities in ovarian SAHA and explored whether it is associated with a more insulin-resistant profile. In all, 316 patients with a diagnosis of polycystic ovary syndrome (PCOS) (56 with SAHA) and 102 age-matched healthy women were examined and underwent a 2-hour oral glucose tolerance test. Serum glucose homeostasis parameters, hormones, and adipokines were determined. SAHA prevalence was 17.7% in patients with PCOS and predominance of the severe PCOS phenotype. Ovarian SAHA was independently associated with a more insulin-resistant profile (higher homeostatic model assessment of insulin resistance score, lower quantitative insulin sensitivity check index [QUICKI] and MATSUDA indices, and relative hypoadiponectinemia), and represented an independent risk factor for glucose abnormalities regardless of anthropometric features, age, and PCOS phenotype. There was no performance of skin biopsies. The prompt recognition of SAHA syndrome in women with PCOS permits an earlier diagnosis and surveillance of metabolic abnormalities, especially in Mediterranean PCOS population exhibiting a lower prevalence of glucose abnormalities.

With the completion of the human genome project, novel sequencing and genotyping technologies had been utilized to detect mutations. Such mutations have continually been produced at exponential rate by researchers in various communities. Based on the population's mutation spectra, occurrences of Mendelian diseases are different across ethnic groups. A proportion of Mendelian diseases can be observed in some countries at higher rates than others. Recognizing the importance of mutation effects in Thailand, we established a National and Ethnic Mutation Database (NEMDB) for Thai people. This database, named Thailand Mutation and Variation database (ThaiMUT), offers a web-based access to genetic mutation and variation information in Thai population. This NEMDB initiative is an important informatics tool for both research and clinical purposes to retrieve and deposit human variation data. The mutation data cataloged in ThaiMUT database were derived from journal articles available in PubMed and local publications. In addition to collected mutation data, ThaiMUT also records genetic polymorphisms located in drug related genes. ThaiMUT could then provide useful information for clinical mutation screening services for Mendelian diseases and pharmacogenomic researches. ThaiMUT can be publicly accessed from http://gi.biotec.or.th/thaimut.

Nonhuman primate models are needed for evaluations of proposed strategies targeting residual virus that persists in HIV-1-infected individuals receiving suppressive combination antiretroviral therapy (cART). However, relevant nonhuman primate (NHP) models of cART-mediated suppression have proven challenging to develop. We used a novel three-class, six-drug cART regimen to achieve durable 4.0- to 5.5-log reductions in plasma viremia levels and declines in cell-associated viral RNA and DNA in blood and tissues of simian immunodeficiency virus SIVmac239-infected Indian-origin rhesus macaques, then evaluated the impact of treatment with the histone deacetylase inhibitor (HDACi) suberoylanilide hydroxamic acid (SAHA; Vorinostat) on the residual virus pool. Ex vivo SAHA treatment of CD4+ T cells obtained from cART-suppressed animals increased histone acetylation and viral RNA levels in culture supernatants. cART-suppressed animals each received 84 total doses of oral SAHA. We observed SAHA dose-dependent increases in acetylated histones with evidence for sustained modulation as well as refractoriness following prolonged administration. In vivo virologic activity was demonstrated based on the ratio of viral RNA to viral DNA in peripheral blood mononuclear cells, a presumptive measure of viral transcription, which significantly increased in SAHA-treated animals. However, residual virus was readily detected at the end of treatment, suggesting that SAHA alone may be insufficient for viral eradication in the setting of suppressive cART. The effects observed were similar to emerging data for repeat-dose SAHA treatment of HIV-infected individuals on cART, demonstrating the feasibility, utility, and relevance of NHP models of cART-mediated suppression for in vivo assessments of AIDS virus functional cure/eradication approaches.

In recent years, Thai indigenous chickens have increasingly been bred as an alternative in Thailand poultry market. Due to their popularity, there is a clear need to improve the underlying quality and productivity of these chickens. Studying chicken genetic variation can improve the chicken meat quality as well as conserving rare chicken species. To begin with, a minimal set of molecular markers that can characterize the Thai indigenous chicken breeds is required. Using AFLP-PCR, 30 single nucleotide polymorphisms (SNPs) from Thai indigenous chickens were obtained by DNA sequencing. From these SNPs, we genotyped 465 chickens from 7 chicken breeds, comprising four Thai indigenous chicken breeds--Pradhuhangdum (PD), Luenghangkhao (LK), Dang (DA) and Chee (CH), one wild chicken--the red jungle fowls (RJF), and two commercial chicken breeds--the brown egg layer (BL) and commercial broiler (CB). The chicken genotypes reveal unique genetic structures of the four Thai indigenous chicken breeds. The average expected heterozygosities of PD=0.341, LK=0.357, DA=0.349 and CH=0.373, while the references RJF= 0.327, CB=0.324 and BL= 0.285. The F(ST) values among Thai indigenous chicken breeds vary from 0.051 to 0.096. The F(ST) values between the pairs of Thai indigenous chickens and RJF vary from 0.083 to 0.105 and the FST values between the Thai indigenous chickens and the two commercial chicken breeds vary from 0.116 to 0.221. A neighbour-joining tree of all individual chickens showed that the Thai indigenous chickens were clustered into four groups which were closely related to the wild RJF but far from the commercial breeds. Such commercial breeds were split into two closely groups. Using genetic admixture analysis, we observed that the Thai indigenous chicken breeds are likely to share common ancestors with the RJF, while both commercial chicken breeds share the same admixture pattern. These results indicated that the Thai indigenous chicken breeds may descend from the

Of the different hydroxamate-based histone deacetylase (HDAC) inhibitors, Suberoylanilide hydroxamic acid (SAHA) has been approved by the FDA for treatment of T-cell lymphoma. Interestingly, a structurally similar inhibitor, Trichostatin A (TSA), which has a higher in vitro inhibitory-potency against HDAC8, reportedly shows a poor efficacy in clinical settings. In order to gain the molecular insight into the above discriminatory feature, we performed transient kinetic and isothermal titration calorimetric studies for the interaction of SAHA and TSA to the recombinant form of human HDAC8. The transient kinetic data revealed that the binding of both the inhibitors to the enzyme showed the biphasic profiles, which represented an initial encounter of enzyme with the inhibitor followed by the isomerization of the transient enzyme-inhibitor complexes. The temperature-dependent transient kinetic studies with the above inhibitors revealed that the bimolecular process is primarily dominated by favorable enthalpic changes, as opposed to the isomerization step; which is solely contributed by entropic changes. The standard binding-enthalpy (ΔH0) of SAHA, deduced from the transient kinetic as well as the isothermal titration calorimetric experiments, was 2–3 kcal/mol higher as compared to TSA. The experimental data presented herein suggests that SAHA serves as a preferential (target-specific/selective) HDAC8 inhibitor as compared to TSA. Arguments are presented that the detailed kinetic and thermodynamic studies may guide in the rational design of HDAC inhibitors as therapeutic agents. PMID:24079912

Muay Thai kickboxing is a common sport that uses the foot and ankle in fighting. Muay Thai kickboxing trainees usually receive training in Thailand Foot and ankle problems in this group ofpeople who usually train barefoot remain unexplored To evaluate the prevalence of common foot and ankle problems in Muay Thai kick boxers. The present study is a cross-sectional survey of Muay Thai kick boxers practicing in northern Thailand. Interviews were conducted and foot and ankle examinations were evaluated Foot morphology was examined using a Harris mat footprint. One hundred and twenty-three Muay Thai kickbox ersinnine training gyms were included in this study. Common foot and ankle problems found in the Muay Thai kick boxers were callosity (59%), gastrocnemius contracture (57%), toe deformities (49.3%), wounds (10%) and heel pain (9%). Callosity was most commonly found on the forefoot (77.5%), on the plantar first metatarsal (55.3%) and on the big toe (33.3%). An association was found between a tight heel cord and a history of foot injury with prolonged periods of weekly training. Toe deformities such as hallux rigidus (37.6%) were also associated with prolonged periods of training (p = 0.001). No correlation was found between type of foot arch and foot and ankle problems. Plantar forefoot callosities and wounds as well as toe deformities including tight heel cords are some of the foot and ankle problems commonly found in Muay Thai kick boxers. They are associated with prolonged periods of barefoot training. The unique pattern of training and of the kicks in Muay Thai might be a path mechanism, leading to the development of foot and ankle problems.

Systemic mastocytosis (SM) is a clonal bone marrow disorder, where therapeutical options are limited. Over 90% of the patients carry the D816V point mutation in the KIT receptor that renders this receptor constitutively active. We assessed the sensitivity of primary mast cells (MC) and mast cell lines HMC1.2 (D816V mutated), ROSA (KIT WT) and ROSA (KIT D816V) cells to histone deacetylase inhibitor (HDACi) treatment. We found that of four HDACi, suberoyl anilide hydroxamic acid (SAHA) was the most effective in killing mutated MC. SAHA downregulated KIT, followed by major MC apoptosis. Primary SM patient MC cultured ex vivo were even more sensitive to SAHA than HMC1.2 cells, whereas primary MC from healthy subjects were less affected. There was a correlation between cell death and SM disease severity, where cell death was more pronounced in the case of aggressive SM, with almost 100% cell death among MC from the mast cell leukemia patient. Additionally, ROSA (KIT D816V) was more affected by HDACi than ROSA (KIT WT) cells. Using ChIP qPCR, we found that the level of active chromatin mark H3K18ac/H3 decreased significantly in the KIT region. This epigenetic silencing was seen only in the KIT region and not in control genes upstream and downstream of KIT, indicating that the downregulation of KIT is exerted by specific epigenetic silencing. In conclusion, KIT D816V mutation sensitized MC to HDACi mediated killing, and SAHA may be of value as specific treatment for SM, although the specific mechanism of action requires further investigation.

The formulation of histone deacetylase inhibitors (HDACi) is challenging due to poor water solubility and rapid elimination of drugs in vivo. This study investigated the effects of complexing iron (Fe3+) to the HDACi suberoylanilide hydroxamic acid (SAHA) and LAQ824 (LAQ) prior to their encapsulation into PEGylated liposomes, and investigated whether this technique could improve drug solubility, in vitro release and in vivo pharmacokinetic (PK) properties. METHODS. The reaction stoichiometry, binding constants and solubility were measured for Fe complexes of SAHA and LAQ. The complexes were passively encapsulated into PEGylated liposomes and characterized by size distribution, zeta-potential, encapsulation efficiency (EE), and in vitro drug release studies. PC-3 cells were used to verify the in vitro anticancer activity of the formulations. In vivo pharmacokinetic properties of liposomal LAQ-Fe (L-LAQ-Fe) was evaluated in rats. RESULTS. SAHA and LAQ form complexes with Fe at 1:1 stoichiometric ratio, with a binding constant on the order of 104 M-1. Fe complexation improved the aqueous solubility and the liposomal encapsulation efficiency of SAHA and LAQ (29-35% EE, final drug concentration > 1 mM). Liposomal encapsulated complexes (L-HDACi-Fe) exhibited sustained in vitro release properties compared to L-HDACi but cytotoxicity on PC-3 cells was comparable to free drugs. The PK of L-LAQ-Fe revealed 15-fold improvement in the plasma t1/2 (12.11 h)and 211-fold improvement in the AUC∞ (105.7 µg·h/ml) compared to free LAQ (0.79 h, 0.5 µg·h/ml). Similarly, the plasma t1/2 of Fe was determined to be 11.83 h in a separate experiment using radioactive Fe-59. The majority of Fe-59 activity was found in liver and spleen of rats and correlates with liposomal uptake by the mononuclear phagocyte system. CONCLUSIONS.

The fluidity of Thai women's gendered and sexual subjectivities.

2004-05-01

This paper reports on an ethnographic study of gender and sexuality as factors within contemporary Thai factory women's subjectivities. Competing discourses of what it means to be a woman in contemporary Thai society make women's self-presentations fluid and incoherent. Data from participant-observation and open-ended interviews suggest that the fluidity and inconsistency of women's self-presentations reflect both their negative experiences and oppression within the Thai patriarchal system, and women's strength and resistance to the normative discourses that oppress them. By naming or reinterpreting experiences and desires in their own terms, Thai factory women can redraw elements of their own lives.

Clinical application of cisplatin against cholangiocarcinoma is often associated with resistance and toxicity posing urgent demand for combination therapy. In this study, we evaluated the combined anticancer effect of cisplatin and histone deacetylase inhibitors (HDACIs), suberoylanilide hydroxamic acid (SAHA) and trichostatin A (TSA), on the cholangiocarcinoma KKU-100 and KKU-M214 cell lines. Antiproliferative activity was evaluated using MTT assay. Apoptosis induction and cell cycle arrest were analyzed by flow cytometry. Cell cycle and apoptosis regulating proteins were evaluated by western blot analysis. MTT assay showed that cisplatin, SAHA and TSA dose-dependently reduced the viability of KKU-100 and KKU-M214 cells. The combination of cisplatin and HDACIs exerted significantly more cytotoxicity than the single drugs. Combination indices below 1.0 reflect synergism between cisplatin and HDACIs, leading to positive dose reductions of cisplatin and HDACIs. Cisplatin and HDACIs alone induced G0/G1 phase arrest in KKU-100 cells, but the drug combinations increased sub-G1 percent more than either drug. However, cisplatin and HDACIs alone or in combination increased only the sub-G1 percent in KKU-M214 cells. Annexin V-FITC staining revealed that cisplatin and HDACIs combinations induced more apoptotic cell death of both KKU-100 and KKU-M214 cells than the single drug. In KKU-100 cells, growth inhibition was accompanied by upregulation of p53 and p21 and downregulation of CDK4 and Bcl-2 due to exposure to cisplatin, SAHA and TSA alone or in combination. Moreover, combination of agents exerted higher impacts on protein expression. Single agents or combination did not affect p53 expression, however, combination of cisplatin and HDACIs increased the expression of p21 in KKU-M214 cells. Taken together, cisplatin and HDACIs combination may improve the therapeutic outcome in cholangiocarcinoma patients.

Currently, dacarbazine (DTIC) is the only approved systemic treatment for metastatic malignant melanoma. However, the modest treatment effect encourages studies on novel therapeutic molecules, delivery systems and combination therapies. Full-length TRAIL, delivered from an adenoviral vector (Ad-hTRAIL), was studied in combination with DTIC or the histone deacetylase inhibitor suberoylanilide hydroxamic acid (SAHA) in human melanoma cell lines. The cytotoxic potential of the combination treatments was assessed by cell viability measurements and CalcuSyn analysis. Involvement of apoptosis was analyzed by TUNEL staining, mitochondrial membrane potential measurements, and activation and expression levels of caspases and other mediators of apoptosis. Ad-hTRAIL in combination with DTIC or SAHA resulted in additive or synergistic growth inhibition compared to each treatment used as single agent. Both combinations augmented apoptosis, which was mediated through the death receptor (DR) pathway by enhanced activation of caspase-8, and through increased loss of mitochondrial integrity. Provoked cleavage of Bid, which bridges the extrinsic and intrinsic apoptosis pathways, and downregulation of the anti-apoptotic mediators Bcl-X(L), Mcl-1 and XIAP (but not Bcl-2) were critical contributing factors. Increased levels of DR4 and DR5 were not a common underlying mechanism as DTIC did not affect the levels of either of the receptors. However, SAHA-induced expression of DR4 may have reduced the TRAIL resistance in the SKMEL-28 cell line. Administration of Ad-hTRAIL in combination with DTIC or SAHA enhances apoptosis in human melanoma cell lines, and suggests that the therapeutic potential of such treatment strategies should be further evaluated for possible clinical use.

The authors examined the relationship between socioeconomic status and smoking in Thai adults. A nationally representative sample of 7858 Thais adults (18 years and older) was surveyed during 2004 to 2005. Four demographic/socioeconomic indicators were examined in logistic models: gender, education, occupational status, and annual household income. Overall, 22.2% of the participants were smokers. Men were more likely to be smokers across all age groups and regions. Compared with nonsmokers, current smokers were less educated, more likely to be employed, but had lower household income. When stratified by gender, education and job levels were strongly associated with smoking prevalence among males. A significant relationship was found between annual household income and smoking. Those who lived under the poverty line were more likely to smoke than persons who lived above the poverty line in both genders. The present study demonstrated that socioeconomic factors, especially education level and occupational class, have a strong influence on smoking behavior in Thai adults.

We report the differences in light stable isotopes between two kinds of Thai rice (Thai jasmine and Sungyod rice). Thai jasmine rice and Sungyod rice were cultivated in the northeast and the south of Thailand. Light isotopes including 13C, 15N and 18O of Thai jasmine rice and Sungyod rice samples were carried out using isotope ratio mass spectrometry (IRMS). Thai jasmine rice (Khao Dawk Mali 105) was cultivated from Thung Kula Rong Hai area, whereas Sungyod rice was cultivated from Phathalung province. Hypothesis testing of difference of each isotope between Thai jasmine rice and Sungyod rice was also studied. The study was the feasibility test whether the light stable isotopes can be the variables to identify Thai jasmine rice and Sungyod rice. The result shows that there was difference in the isotope patterns of Thai jasmine rice and Sungyod rice. Our results may provide the useful information in term of stable isotope profiles of Thai rice.

Assess the reliability and validity of the Thai translation of the CHOICE Health Experience Questionnaire (CHEQ), which is the English-language questionnaire, developed specifically for End-stage-renal disease (ESRD) patients. The CHEQ comprised of two parts, nine general domains of SF-36 (physical function, role-physical, bodily pain, mental health, role-emotional, social function, vitality, general health, and report transition) and 16 dialysis specific domains of the CHEQ (role-physical, mental health, general health, freedom, travel restriction, cognitive function, financial function, restriction diet and fluids, recreation, work, body image, symptoms, sex, sleep, access, and quality of life). The authors translated the CHEQ questionnaire into Thai and confirmed the accuracy by back translation. Pilot study sample was 10 Thai ESRD patients. Then the CHEQ (Thai) was applied to 110 Thai ESRD patients. Twenty-three patients had chronic peritoneal dialysis patients and 87 were chronic intermittent hemodialysis patients. Statistical analysis included descriptive statistics, Mann-Whitney U test, Student's t-test, and Cronbach's alpha. Construct validity was satisfactory with the significant difference less than 0.001 between the low and high group. The reliability coefficient for the Cronbach's alpha of the total scale of the CHEQ (Thai) was 0.98. The Cronbach 's alphas were greater than 0.7 for all domains, range from 0.58 to 0.92, except the social function and quality of life domain (alpha = 0.66 and 0.575). The CHEQ (Thai) is reliable and valid for assessment of Thai ESRD patients receiving chronic dialysis. Its properties are similar to those reported in the original version.

Trees with larvicidal activity may be found in Thailand. We conducted this study to evaluate the efficacy and length of efficacy of Thai neem (Azadirachta siamensis) oil emulsion and an alginate bead of Thai neem oil formulation against early fourth stage Aedes aegypti larvae using a dipping test. The Thai neem oil emulsion had significantly greater larvicidal activity than the alginate bead formulation at 12 to 60 hours post-exposure (p < 0.01). The Thai neem oil formulation resulted in 100% mortality among the early fourth stage Aedes aegypti larvae at 48 hours, while the alginate bead formulation resulted in 98% larval mortality at 84 hours and 100% mortality at 96 hours. The mean larval mortality using the Thai neem oil emulsion dropped to < 25% by 12 days and with the alginate beads dropped to < 25% by 15 days of exposure.

Background Duffy (FY) blood group genotyping is important in transfusion medicine because Duffy alloantibodies are associated with delayed hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. In this study, FY allele frequencies in Thai blood donors were determined by in-house PCR with sequence-specific primers (PCR-SSP), and the probability of obtaining compatible blood for alloimmunized patients was assessed. Methods Five hundred blood samples from Thai blood donors of the National Blood Centre, Thai Red Cross Society, were included. Only 200 samples were tested with anti-Fya and anti-Fyb using the gel technique. All 500 samples and four samples from a Guinea family with the Fy(a-b-) phenotype were genotyped by using PCR-SSP. Additionally, the probability of obtaining antigen-negative red blood cells (RBCs) for alloimmunized patients was calculated according to the estimated FY allele frequencies. Results The FY phenotyping and genotyping results were in 100% concordance. The allele frequencies of FY*A and FY*B in 500 central Thais were 0.962 (962/1,000) and 0.038 (38/1,000), respectively. Although the Fy(a-b-) phenotype was not observed in this study, FY*BES/FY*BES was identified by PCR-SSP in the Guinea family and was confirmed by DNA sequencing. Conclusions Our results confirm the high frequency of the FY*A allele in the Thai population, similar to that of Asian populations. At least 500 Thai blood donors are needed to obtain two units of antigen-negative RBCs for the Fy(a-b+) phenotype. PMID:26354350

This study explored the lived experiences of Thai women in relation to alcohol addiction in treatment. Twelve women aged 20 to 65 years, were participated. The participants were recruited from two special hospitals and one outpatient clinic in a general hospital. Descriptive phenomenology was applied to analyze the transcripts of the individual interviews. The explored phenomenon of Thai women experiencing alcohol addiction included four essential aspects, (1) feeling inferior and worthless (2) feeling physically and emotionally hurt, (3) fearing physical deterioration and premature death, and (4) feeling superior and powerful. Through these different aspects of Thai women's lived experiences, the following essence was synthesized. The essence of the lived experience of alcohol addiction among the studied Thai women was ambivalence between feeling inferior and worthless and feeling superior and powerful when acting as a man. Drinking alcohol lessened life's difficulties and fears; for example, of violence, bodily demolition, premature death and marginalization from family and society. Thai women who experience alcohol addiction are treated with gender-related double standards when trying to undo gender traditional roles. Their marginalization from family and society deepens making them even more vulnerable to the positive side effects of alcohol drinking. Copyright © 2017. Published by Elsevier B.V.

Objective To evaluate the curricula content of Thai pharmacy schools based on the Thai pharmacy competency standards. Methods Course syllabi were collected from 11 pharmacy schools. A questionnaire was developed based on the Thai pharmacy competency standards. Course coordinators completed the questionnaire assessing the curricula content. Results The curricula for both the bachelor of science in pharmacy degree (BS Pharm) and doctor of pharmacy (PharmD) degree programs included the minimum content required by the 8 competency domains. The dominant content area in BS Pharm degree programs was product-oriented material. The content ratio of patient to product to social and administrative pharmacy in the BS Pharm degree programs was 2:3:1, respectively. However, the content ratio suggested by the Thai Pharmacy Council was 3:2:1, respectively. For the PharmD programs, the largest content area was patient-oriented material, which was in agreement with the framework suggested by the Thai Pharmacy Council. Conclusions The curricula of all Thai pharmacy schools met the competency standards; however, some patient-oriented material should be expanded and some product-oriented content deleted in order to meet the recommended content ratio.

Tone classification of syllable-segmented Thai speech based on multilayer perception

Satravaha, Nuttavudh; Klinkhachorn, Powsiri; Lass, Norman

2002-05-01

Thai is a monosyllabic tonal language that uses tone to convey lexical information about the meaning of a syllable. Thus to completely recognize a spoken Thai syllable, a speech recognition system not only has to recognize a base syllable but also must correctly identify a tone. Hence, tone classification of Thai speech is an essential part of a Thai speech recognition system. Thai has five distinctive tones (``mid,'' ``low,'' ``falling,'' ``high,'' and ``rising'') and each tone is represented by a single fundamental frequency (F0) pattern. However, several factors, including tonal coarticulation, stress, intonation, and speaker variability, affect the F0 pattern of a syllable in continuous Thai speech. In this study, an efficient method for tone classification of syllable-segmented Thai speech, which incorporates the effects of tonal coarticulation, stress, and intonation, as well as a method to perform automatic syllable segmentation, were developed. Acoustic parameters were used as the main discriminating parameters. The F0 contour of a segmented syllable was normalized by using a z-score transformation before being presented to a tone classifier. The proposed system was evaluated on 920 test utterances spoken by 8 speakers. A recognition rate of 91.36% was achieved by the proposed system.

This paper aimed to demonstrate the research and development of a rule-based expert system for skin problem consulting in the areas of acne, melasma, freckle, wrinkle, and uneven skin tone, with recommended treatments from Thai traditional medicine knowledge. The tool selected for developing the expert system is a software program written in the PHP language. MySQL database is used to work together with PHP for building database of the expert system. The system is web-based and can be reached from anywhere with Internet access. The developed expert system gave recommendations on the skin problem treatment with Thai herbal recipes and Thai herbal cosmetics based on 416 rules derived from primary and secondary sources. The system had been tested by 50 users consisting of dermatologists, Thai traditional medicine doctors, and general users. The developed system was considered good for learning and consultation. The present work showed how such a scattered body of traditional knowledge as Thai traditional medicine and herbal recipes could be collected, organised and made accessible to users and interested parties. The expert system developed herein should contribute in a meaningful way towards preserving the knowledge and helping promote the use of Thai traditional medicine as a practical alternative medicine for the treatment of illnesses.

2015-01-01

The purpose of the present study was to establish normal electroretinogram (ERG) parameters using 56 normal eyes of four dog breeds common in Thailand: poodle, Labrador retriever, Thai ridgeback, and Thai Bangkaew. Standard ERG findings were bilaterally recorded using a handheld multi-species ERG unit with an ERG-jet lens electrode for 28 dogs under preanesthesia with diazepam, anesthesia with propofol, and anesthesia maintenance with isoflurane. There were significant differences in the mean values of ERG amplitudes and implicit times among the four dog breeds (p < 0.05) except for the b-wave implicit time of the photopic 30 Hz flicker response with 3 cd.s/m2 (p = 0.610). Out of the four breeds, Thai Bangkaew had the longest implicit time (p < 0.001) of scotopic low intensity responses, b-wave of scotopic standard intensity responses (3 cd.s/m2), a-wave of the higher intensity response (10 cd.s/m2), and a-wave of the photopic single flash response (3 cd.s/m2). For the b/a ratio, only the ratio of the Cone response was significantly different among the different breeds. In this summary, normal ERG parameters for four dog breeds were reported. Data from the investigation supported the hypothesis that determination of breed-specific limits of normality for ERG responses is necessary for individual clinics and laboratories. PMID:25269713

Viral reservoirs-persistent residual virus despite combination antiretroviral therapy (cART)-remain an obstacle to cure of HIV-1 infection. Difficulty studying reservoirs in patients underscores the need for animal models that mimics HIV infected humans on cART. We studied SIV-infected Chinese-origin rhesus macaques (Ch-RM) treated with intensive combination antiretroviral therapy (cART) and 3 weeks of treatment with the histone deacetyalse inhibitor, suberoylanilide hydroxamic acid (SAHA). SIVmac251 infected Ch-RM received reverse transcriptase inhibitors PMPA and FTC and integrase inhibitor L-870812 beginning 7 weeks post infection. Integrase inhibitor L-900564 and boosted protease inhibitor treatment with Darunavir and Ritonavir were added later. cART was continued for 45 weeks, with daily SAHA administered for the last 3 weeks, followed by euthanasia/necropsy. Plasma viral RNA and cell/tissue-associated SIV gag RNA and DNA were quantified by qRT-PCR/qPCR, with flow cytometry monitoring changes in immune cell populations. Upon cART initiation, plasma viremia declined, remaining <30 SIV RNA copy Eq/ml during cART, with occasional blips. Decreased viral replication was associated with decreased immune activation and partial restoration of intestinal CD4+ T cells. SAHA was well tolerated but did not result in demonstrable treatment-associated changes in plasma or cell associated viral parameters. The ability to achieve and sustain virological suppression makes cART-suppressed, SIV-infected Ch-RM a potentially useful model to evaluate interventions targeting residual virus. However, despite intensive cART over one year, persistent viral DNA and RNA remained in tissues of all three animals. While well tolerated, three weeks of SAHA treatment did not demonstrably impact viral RNA levels in plasma or tissues; perhaps reflecting dosing, sampling and assay limitations.

Sentence similarity computation plays an increasingly important role in text mining, Web page retrieval, machine translation, speech recognition and question answering systems. Thai language as a kind of resources scarce language, it is not like Chinese language with HowNet and CiLin resources. So the Thai sentence similarity research faces some challenges. In order to solve this problem of the Thai language sentence similarity computation. This paper proposes a novel method to compute the similarity of Thai language sentence based on syntactic structure and semantic vector. This method firstly uses the Part-of-Speech (POS) dependency to calculate two sentences syntactic structure similarity, and then through the word vector to calculate two sentences semantic similarity. Finally, we combine the two methods to calculate two Thai language sentences similarity. The proposed method not only considers semantic, but also considers the sentence syntactic structure. The experiment result shows that this method in Thai language sentence similarity computation is feasible.

To explore the way Thai patients perceive and manage their diabetes. Using a focused ethnographic approach, face-to-face interviews were conducted at two public hospitals in Bangkok. All interviews (n=27) were audio-taped and transcribed verbatim. Analysis of the interview transcripts was completed thematically. The findings showed that Thai patients manage their diabetes according to their beliefs about diabetes. These beliefs are constructed using both modern and traditional knowledge. For example, some patients explained the cause of their illness as being due to biomedical factors such as genetics, and also cultural factors such as karma from either previous or current lifetimes. The analysis also revealed that some aspects of Thai life facilitate diabetes self-management while other aspects hamper good control of the illness. For example, Buddhist values of moderation contribute positively to dietary change, while, on the other hand, the importance of rice in the Thai diet can impede successful self-management strategies. The results of this research indicate that Thai culture influences diabetes perceptions and management. Culturally appropriate treatment guidelines should be established for diabetes management that give special consideration to the significance and meaning of food and to Buddhist beliefs.

The present research aims to examine the cranial index in a modern people of Thai ancestry. Ultimately, this study will help to create a databank containing a cranial index for the classifications of the people from Asia. In this study, 185 modern crania of people of supposed Thai ancestry were examined. They were collected from the Department of Anatomy at Chulalongkorn University in Bangkok, Thailand. The maximum cranial length and breadth were measured using standard anthropometric instruments based on Martin's methods. The cranial index was calculated using the equation ([maximum cranial breadth/maximum cranial length]×100). The mean cranial indices for the male and female skulls examined were 81.81±4.23 and 82.99±4.37, respectively. The most common type of skull in the modern Thai people in this study was the brachycranic type with a frequency of 42.7%, followed by the mesocranic (27.03%) and hyperbrachycranic types (25.59%). The rarest type observed in this study was the dolichocranic type (4.32%). The present study provides valuable data pertaining to the cranial index in a modern Thai population and reveals that modern Thai males and females belong to the brachycranic group. The results of this study will be of forensic anthropological importance to populations in close proximity to the location where the skulls studied here were sourced. PMID:29644107

Problems from improper shoe fitting are common, but there are limited foot data for the older Thai population. To study foot dimensions and determine proper shoe sizes for Thai elderly. Healthy older people: 108 men, 105 women, aged 60-80 years, who were independent in walking, were recruited. Thirteen foot dimensions and current shoes used were measured. Side-to-side, gender difference, and correlations of main foot measurements were analyzed. About 50% women and 34% men wore too narrow shoes, and this was found to be associated with foot pain. At the same foot length (FL), men had larger foot width (FW) and toe depth. Foot width=2.39+(0.29 x FL), r=0.50, p=0.001 for women and=2.48+(0.31 x FL), r=0.56, p=0.002 for men. Arch length=1.0+(0.7 x FL), r=0.93, p=0.001 for both genders. Toe depth had constant values in all shoe sizes of each gender. Correlations of other foot parameters were reported. These anthropometric data is essential for proper shoe fitting in order to provide foot ergonomics and prevent foot problems for older Thai people.

Comparison of Balance Performance Between Thai Classical Dancers and Non-Dancers.

Thai classical dance is a traditional dramatic art, the technique of which has many features in common with South East Asian performing art. The choreographic patterns consist of various forms of balance control together with limb movements in slow rhythm. The grace and beauty of the dancer are dependent on how well the limb movements curve and angle. The relationship of whole body proportion and balance control in various patterns of support base is also important. The purpose of this study was to compare balance abilities between Thai classical dancers and non-dancers in different balance conditions. Twenty-five Thai classical dancers and 25 non-dancers performed the modified Sensory Organization Test (mSOT) and were further challenged by adding dynamic head tilts (DHTs) in four different directions during mSOT. Mixed model ANOVA was applied to determine the equilibrium score in each balance condition and also the interaction between dancer and non-dancer groups. It was found that Thai classical dancers achieved better equilibrium scores in all mSOT conditions except the least challenging one. Moreover, additional multitask conditions (mSOT+DHT) were revealed to profoundly affect differences between dancers and controls. In conclusion, Thai classical dancers demonstrated a better ability to maintain postural stability during different challenging postural tests. This information suggests various ways of putting the practice of Thai classical dance to use in the future.

An experimental setup for studying the influence of the radial electric field on very low qa plasma on the Saha Institute of Nuclear Physics tokamak is presented. A high current, high voltage pulsed power supply, using a semiconductor controlled rectifier (SCR) as a dc switch is developed and used to bias a tungsten electrode inserted inside the plasma. The electrode's exposed length and its position inside the plasma are controlled by a double bellows assembly to optimize the electrode-exposed length. We show that using the force commutation method to turn the SCR off to get the power pulse desired has good potential for carrying out similar kinds of studies, especially in a low budget small tokamak.

Even though there have been a reported sex estimation method by using femur in Thais, the temporal change related to time and anthropological data need to be renewed. Thus the aim of this study is to re-evaluate sex estimation by femur in Thais. 97 adult male and 103 female femora were random chosen from Forensic osteology research center and 6 measurements were applied tend to. To compare with previous Thai data, mid shaft diameter to increase but femoral head and epicondylar breadth to stabilize and when tested previous discriminant function by vertical head diameter and epicondalar breadth, the accuracy of prediction was lower than previous report. From the new data, epicondalar breadth is the best variable for distinguishing male and female at 88.7 percent of accuracy, following by transverse and vertical head diameter at 86.7 percent and femoral neck diameter at 81.7 percent of accuracy. Multivariate discriminant analysis indicated transverse head diameter and epicondylar breadth performed highest rate of accuracy at 89.7 percent. The percent of accuracy of femur was close to previous reported sex estimation by talus and calcaneus in Thai population. Thus, for especially in case of lower limb remain, which absence of pelvis.

We explored how Thai female adolescents describe the meaning and context of dating violence. Twenty-four students, aged 15-17, were purposively recruited from a secondary school in Bangkok for individually audio-taped interviews. The interviews lasted 45- 70 minutes. ATLAS ti 5.2 was selected for content analysis. Five themes emerged, including characteristics of adolescent romantic relationships, influences on adolescent romantic relationships, perceptions of dating violence, cycle of dating-violence experiences, and influences on adolescents' perceptions of dating violence. The findings indicate a foundation for developing culturally sensitive programs for dating-violence prevention among Thai adolescents.

To determine the prevalence ofFacebook (FB) addiction and its related factors among Thai high school students. This cross-sectional study was performed among 972 high school students in four provinces associated with high economic prosperity in Thailand: Bangkok, Ubon Ratchathani, Chiang Mai and Songkhla, utilizing a multistage cluster sampling technique. A self-administrative questionnaire was produced composing of three parts; demographic data, a Thai version of the Bergen Facebook Addiction Scale (Thai-BFAS) and the Thai version of the General Health Questionnaire-28 items. Multivariate analysis was employed to analyze thefactors associated with FB addiction. The prevalence ofFB addiction amongst Thai adolescents was 41.8% (95% CI; 38.6, 45.2). Related factors included gender school location, sufficiency ofpersonalfinance, devices ofFB access, duration ofstaying online via FB, andFB usage during holidays. In addition, every 1-hour increase in usage enhanced the risk for FB addiction (OR = 1.12, 95% CI; 1.05, 1.19). The prevalence of FB addiction in Thai high school students was found to be higher than in many other countries. Relatedfactors should be controlled in order to reduce FB addiction and its detrimental impacts, such as behavior modification and the promotion of healthier free-time activities. Further studies are recommended to understand why FB addiction is so high in Thailand.

The voice handicap index (VHI) is one of the most utilized instruments for measuring a patient's self-assessment of voice severity. The VHI has been translated into several languages, but not in Thai. To examine the psychometric properties of a Thai translation of the voice Handicap Index (VHI) and assess the applicability in the screening diagnosis. After receiving permission from the American Speech Language Hearing Association (ASHA), the original VHI had been translated and adapted to Thai by forward and backward standard translation. Eighty-five patients with voice disorders, divided in four groups according to the etiology of the diseases (neurogenic, structural, functional, and inflammatory), and 30 asymptomatic subjects were included in the present study. Internal consistency was analyzed through Cronbach's a coefficient. For the VHI test-retest reliability analysis, the Thai VHI was completed twice by 22 patients and assessed through the intraclass correlation coefficient. For clinical validity evaluation, the VHI scores from the pathological group were compared with the control group and compared among the four different pathological groups. The cutoff point for distinguishing the normal from the patient group was assessed by ROC analysis. Effects of age and gender on VHI scores were also evaluated. The Thai VHI showed a significant high internal consistency and test-retest reliability (Cronbach's α = 0.96 and r = 0.843, respectively). Mann-Whitney U test was used to compare the control group and pathological groups and revealed significant difference in total scores and its three domains scores (p < 0.001). ROC analysis demonstrated that a VHI score of 13 should be considered the threshold for revealing the impact of quality of life in voice disorder patients. Age and gender were not affect the VHI scores in both control and patient groups. The Thai VHI has high reliability and validity. The Thai version of VHI is considered to be a self-assessment tool

This study, based on data collected in 2005 from Chai Nat province, examines the level of happiness of the Thai elderly population and its relationship to various external and internal factors. It was found that mean happiness was slightly above a feeling of "neutral." According to multiple regression analyses, external factors including economic hardship, living arrangements, functional ability, perceived social environment, and consumerism significantly influence the level of happiness. The strongest predictor of happiness is, however, the internal factor-that is, a feeling of relative poverty when compared to their neighbors. Controlling for demographic and all external factors, the respondents who do not feel poor show the highest level of happiness compared to those who feel as poor as or poorer than their neighbors. This is self-interpreted as a feeling of contentment with what one has, which has been influenced by Thai culture, which is pervaded by Buddhism.

This study describes sexual communication among Thai parents and their teens and identifies variables related to communication about sex in urban Thai families. Data were derived from 420 families whose teenage children ages 13-14 years were randomly selected using the probability proportional to size technique. Interviews were conducted with 1 parent and 1 teenage child in each family. In-depth interviews were also conducted in 30 parents and teens drawn from the same 420 families. Results showed that parents were most likely to talk with their teens about body changes and dating; however, less discussion about sex-related issues, birth control, and HIV/AIDS occurred. More daughters than sons reported frequent discussions with their parents about sex. Parents who believed their teens had been involved in sexual activity were more likely to talk about HIV/AIDS and the difficulty of teenagers having babies, instead of talking about sexual intercourse or when to start having sex. Multiple regression analysis indicated that gender of the child (female), parental religiosity, and parental perception of teen sexual activity were significant predictors of increased sexual communication in Thai families. The findings suggest a need for approaches designed to facilitate communication skills about sex-related issues among Thai parents.

The Thai Anesthesia Incidents study (THAI Study) is the first national study of anesthesia outcomes during anesthesia practice in Thailand. The authors extracted data of 25,098 pediatric cases from the THAI Study in order to examine the incidence, suspected causes, contributory factors, and suggested corrective strategies associated with anesthesia-related cardiac arrest. A multi-centered prospective descriptive study was conducted among 20 hospitals across Thailand over a year between March 1, 2003 and February 28, 2004. Data of cardiac arrests in children aged 15 years and younger were collected during anesthesia, in the recovery room and 24 hours postoperative period, and reviewed independently by at least two reviewers. Incidence of anesthesia- related cardiac arrest was 5.1 per 10,000 anesthetics, with 46% mortality rate. Infants accounted for 61% of cases. Incidences of overall cardiac arrest and anesthesia-related arrest were significantly higher in infants than older children and in children with ASA physical status 3-5 than those with ASA physical status 1-2. Most of the anesthesia-related arrests occurred in the operating room (61%) during induction or maintenance of anesthesia (84%). Respiratory-related cardiac arrest was the most common suspected cause of anesthesia-related cardiac arrest. Improving supervision, additional training, practice guidelines, efficient blood bank, equipment maintenance, and quality assurance monitoring are suggested corrective strategies to improve the quality of care in pediatric anesthesia. The incidence of anesthesia-related cardiac arrest was 5.1:10,000 anesthetics. Major risk factors were children younger than 1 year of age and ASA 3-5. The identifications of airway management and medication-related problems as the main causes of anesthesia-related cardiac arrest have important implications for preventive strategies.

The current aim is to examine the prevalence of intimate partner violence (IPV) among Thai women residing in Sweden and its association with mental health. We also investigate the potential influence of social isolation and social capital regarding the association between IPV and mental health outcome. A public health questionnaire in Thai was distributed by post to the entire population of Thai women, aged 18-64, residing in two regions in Sweden since 2006. Items included aspects related to IPV (physical/sexual/emotional), sociodemographic background, physical health, mental health (GHQ-12), social isolation, and social capital (i.e. social trust/participation). The response rate was 62.3% (n=804). Prevalence of lifetime reported IPV was 22.1%, with 20.5% by a previous partner and 6.7% by a current partner. Previous IPV exposure was significantly related to current IPV exposure, and all IPV exposure measures were significantly related to poor mental health. However, Thai women experiencing IPV by a current partner were more at risk for poor mental health than Thai women with previous or without any experience of IPV. Also, among all women exposed to IPV, those with trust in others and without exposure to social isolation seemed to have partial protection against the adverse mental health consequences associated with IPV. Most Thai women had never been exposed to IPV, and after migrating to Sweden, women had lower IPV exposure than in Thailand. However, the increased risk for poor mental health among those Thai women exposed to IPV suggests the need for supportive measures and targeted interventions to prevent further injuries and adverse health consequences. Although poor mental health in Thai women represents an obstacle for integration, the potential resilience indicated in the group with high social trust and without exposure to social isolation suggests that such aspects be included in the program designed to facilitate integration.

Due to the influence of major elements' self-absorption, scarce observable spectral lines of trace elements, and relative efficiency correction of experimental system, accurate quantitative analysis with calibration-free laser-induced breakdown spectroscopy (CF-LIBS) is in fact not easy. In order to overcome these difficulties, standard reference line (SRL) combined with one-point calibration (OPC) is used to analyze six elements in three stainless-steel and five heat-resistant steel samples. The Stark broadening and Saha - Boltzmann plot of Fe are used to calculate the electron density and the plasma temperature, respectively. In the present work, we tested the original SRL method, the SRL with the OPC method, and intercept with the OPC method. The final calculation results show that the latter two methods can effectively improve the overall accuracy of quantitative analysis and the detection limits of trace elements.

Preservatives are added to cosmetics and other consumer products to prevent microbial growth and product degradation. Many cosmetic preservatives are skin sensitizers and frequent causes of contact dermatitis. The use of preservatives may vary by country and/or region, according to legislation, and may be reflected in differences in the prevalence rates of preservative allergy worldwide. To examine the type and frequency of preservative use in cosmetics sold in Thai markets in metropolitan Bangkok, Thailand. Preservatives contained in 1000 different cosmetics sold in Thai markets were documented and analysed, based on the labelling of ingredients. Most of the cosmetic and skincare products sold in Thai markets were international brands, with only a small proportion of cosmetic products being produced in Thailand. International brand cosmetics were more likely to contain non-formaldehyde-releasing preservatives than domestically produced brands. Isothiazolinone-based preservatives, which are responsible for the current increase in the prevalence of contact allergy, were found at a significant frequency in domestically produced, leave-on cosmetic products. Preservatives in cosmetics were significantly different according to source of production and type of cosmetics. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The association of fractures with thalassaemia syndromes is well established. The aim of this study was to determine the prevalence and risk factors for fracture in Thai people with thalassaemia syndromes. A retrospective study and a patient interview were conducted in 201 Thai thalassaemia patients who attended the Division of Haematology, Department of Medicine Siriraj Hospital, Thailand. The patient interview questionnaire included sections on demographics, medical, orthopaedic and surgical history, usage of tobacco and alcohol, as well as questions that pertained to fracture. The risk factors for fracture were determined by odds ratio. The prevalence of fracture in Thai people with thalassaemia syndromes was 35.3 percent. Fracture occurred more often in beta thalassaemia patients (44.1 percent) than in alpha thalassaemia patients (16.9 percent). Upper extremity was the most common site of fracture, while falls and motor vehicle accidents were the most common causes of fracture, and cast/splint was the most common choice of treatment. 28 percent of the patients sustained multiple fractures. Among alpha thalassaemia patients, adults sustained fractures more frequently than children and adolescents. In contrast, beta thalassaemia children had a greater rate of fracture than the adults and adolescents. The risk factors for fracture in thalassaemia patients included male gender, beta thalassaemia, splenectomy, transfusion and a low body mass index. A high prevalence of fracture is observed among Thais with thalassaemia. The aetiology was found to be multifactorial.

This work aimed to investigate tissue responses and biodegradation, both in vitro and in vivo, of four types of Bombyx mori Thai silk fibroin based-scaffolds. Thai silk fibroin (SF), conjugated gelatin/Thai silk fibroin (CGSF), hydroxyapatite/Thai silk fibroin (SF4), and hydroxyapatite/conjugated gelatin/Thai silk fibroin (CGSF4) scaffolds were fabricated using salt-porogen leaching, dehydrothermal/chemical crosslinking and an alternate soaking technique for mineralization. In vitro biodegradation in collagenase showed that CGSF scaffolds had the slowest biodegradability, due to the double crosslinking by dehydrothermal and chemical treatments. The hydroxyapatite deposited from alternate soaking separated from the surface of the protein scaffolds when immersed in collagenase. From in vivo biodegradation studies, all scaffolds could still be observed after 12 weeks of implantation in subcutaneous tissue of Wistar rats and also following ISO10993-6: Biological evaluation of medical devices. At 2 and 4 weeks of implantation the four types of Thai silk fibroin based-scaffolds were classified as "non-irritant" to "slight-irritant", compared to Gelfoam(®) (control samples). These natural Thai silk fibroin-based scaffolds may provide suitable biomaterials for clinical applications.

To investigate the effects of Thai dancing on median neurodynamic response during 4-hour computer use. Twenty-four healthy participants aged 20-30 years performed 5 minutes of Thai dancing including Prom See Na, Yoong Fon Hang, Sod Soy Mala, Lor Keaw and Cha Nee Rai Mai during a 10-minute break of 4-hour computer use. All participants were assessed for nerve tension by elbow range of motion ofupper limb neurodynamic test 1 (ULNT1) and components of quick test. The discomfort was measured by visual analogue discomfort scale (VADS). These measurements were assessed before and after computer work. The statistical analyses employed paired t-test for continuous outcome and Friedman's test. The median nerve tension (indicated by elbow range of motion) was significantly reduced at before and after work, when 5 minutes of Thai dancing was introduced during the break. While components of the quick test emphasized that Thai dance immediately helped reduce the median nerve tension. The VADS in eight body areas increased over the period of 4 hours, but decreased after performing Thai dancing (p<0.05). Thai dancing helped relieve median nerve tension and body discomfort. It may be recommended as an exercise during break for computer users who continuously work to prevent WMSDs.

The disaster caused by the tsunami of 26 December 2004 was one of the worst that medical systems have faced. The aim of this study was to learn about the medical response of the Thai hospitals to this disaster and to establish guidelines that will help hospitals prepare for future disasters. The Israeli Defense Forces (IDF) Home Front Command (HFC) Medical Department sent a research delegation to Thai hospitals to study: (1) pre-event hospital preparedness; (2) patient evacuation and triage; (3) personnel and equipment reinforcement; (4) modes used for alarm and recruitment of hospital personnel; (5) internal reorganization of hospitals; and (6) admission, discharge, and secondary transfer (forward management) of patients. Thai hospitals were prepared for and drilled for a general mass casualty incident (MCI) involving up to 50 casualties. However, a control system to measure the success of these drills was not identified, and Thai hospitals were not prepared to deal with the unique aspects of a tsunami or to receive thousands of victims. Modes of operation differed between provinces. In Phang Nga and Krabi, many patients were treated in the field. In Phuket, most patients were evacuated early to secondary (district) and tertiary (provincial) hospitals. Hospitals recalled staff rapidly and organized the emergency department for patient triage, treatment, and transfer if needed. Although preparedness was deficient, hospital systems performed well. Disaster management should focus on field-based first aid and triage, and rapid evacuation to secondary hospitals. Additionally, disaster management should reinforce and rely on the existing and well-trusted medical system.

2017-01-01

Living in a care home is a source of stigma in Thai culture, although there is currently no measurement tool in the Thai language specifically designed to assess internalized stigma in care home residents. The Thai Version of Internalized Stigma of Living in a Care Home (TIS-LCH) scale was developed and tested for its psychometric properties among Thai older residents. The Thai version of Internalized Stigma of Mental Health Illness (ISMI) Scale was revised into the TIS-LCH by replacing the word of "mental health illness" to "living in a care home." Content validity of the TIS-LCH was determined through expert review (n = 6), and reliability testing was undertaken with older care home residents (n = 128). The TIS-LCH showed good internal consistency, with a Cronbach's alpha of .87. Test-retest reliability coefficient of TIS-LCH was excellent for the full scale (ICC = .90). The Thai version of IS-LCH (TIS-LCH) is a valid and reliable measurement tool for assessing internalized stigma in Thai care home residents. The IS-LCH will be a useful research tool to assess internalized stigma in older adults living in care settings. Understanding stigma will help health and social care professionals to plan interventions aimed at reducing or preventing negative emotional reactions and negative behavioural responses toward stigma, which are known to be associated with mental illness and particularly depression among this population.

2015-01-01

In this study, a mechanical model was developed, aiming to provide standardized and programmable traditional Thai massage (TTM) therapy to patients. The TTM was modeled and integrated into a mechanical hand (MH) system, and a prototype massage chair was built and tested for user satisfaction. Three fundamental principles of Thai massage were integrated: pull, press, and pin. Based on these principles, the mechanics of Thai massage was studied and a mathematical model was developed to describe the dynamics and conditions for the design and prototyping of an MH. On average, it was found that users were satisfied with the treatment and felt that the treatment was similar to that performed by human hands. According to the interview results, users indicated that they were likely to utilize the MH as an alternative to traditional massage. Therefore, integrated TTM with an MH may help healthcare providers deliver standardized, programmable massage therapy to patients as opposed to variable, inconsistent human massage.

Cultural or ethnic factors may play an important role in subjects' pain reports. The aim of the study was to compare the prevalence of orofacial pain symptoms between Finnish and Thai populations. The Finnish study population comprised the Northern Finland Birth Cohort 1966, of which 5696 subjects participated in the present study. The Thai sample consisted of 1501 randomly selected people living in 10 different districts in Bangkok. Data on orofacial pain was collected based on questionnaires. After adjusting for age, gender and education, the logistic regression analysis showed that Thai subjects had an increased risk for reporting oral pain (OR = 4.5, 95% CI = 3.7-5.4), tooth pain (OR = 2.0, 95% CI = 1.8-2.4) and pain in the face (OR = 1.5, 95% CI = 1.2-1.7). It can be concluded that Thai people report more orofacial pain symptoms than Finnish subjects. Cross-cultural factors exist in the background of reporting pain symptoms in the oral and facial area.

To assess the socioeconomic-related inequality in dental care utilization among Thai elderly and to determine factors associated with the observed inequality after the country achieved universal coverage. The data were taken from the nationally representative Thailand Health & Welfare Survey 2007. Data of 10,096 Thai elderly (aged over 60 years) were selected. Descriptive analyses of the features of dental care utilization among Thai elderly were carried out, in addition to the concentration index (Cindex ) being used to quantify the extent of socioeconomic-related inequality in dental care utilization. Logistic regression was used to determine factors associated with inequality in dental care. Socioeconomic-related inequality in dental care utilization among Thai elderly was shown. Also, utilization was more concentrated among wealthier older adults, as shown by the positive value of Cindex (equals 0.244). The poor elderly, however, were more likely to utilize dental care at public facilities, particularly primary care facilities. Multivariate analysis showed that certain demographic, socioeconomic and geographic characteristics were particularly associated with poor-rich differences in dental care utilization among Thai elderly. Although socioeconomic-related inequality in dental care utilization among Thai elderly exists, the pro-poor utilization at public facilities, particularly primary care facilities, substantiates the concerted effort to reducing inequality in dental care utilization for Thai elderly. © 2012 Japan Geriatrics Society.

The purpose of this study is to explain Thai foreign-policy behavior toward the Arab-Israeli conflict during the Arab oil embargo of 1973-1974 in the wake of the October 1973 War. The major hypothesis is that Thai foreign policy behavior shifted from a neutral to a pro-Arab position after the Arab oil embargo. This shift was motivated by Thai oil-import dependence on OAPEC (Organization of Arab Petroleum Exporting Countries). Oil has assumed an economic as well as a political dimension. Therefore, its political influence over the oil-dependent states cannot be dismissed. Thai foreign-policy behavior in the Arab-Israeli conflict is analyzed throughmore » the use of the dependence approach, which contends that external reliance is a potent factor for explaining behavior of actors. Thailand's foreign-policy stand is first delineated through the use of documents containing policy statements by Thai delegates to the United Nations. It was found that although Thai public policy statements were never bluntly anti-Israel, they moved from between neutrality before the oil crisis to a pro-Arab position after the oil crisis of 1973-1974. This shift of Thailand's foreign policy behavior position was then measured against its UN voting records. Results of the voting analysis indicated that the shifting of Thai foreign policy behavior during the October war was motivated by Thailand's oil-import dependence.« less

Active aging is central to enhancing the quality of life for older adults, but its conceptualization is not often made explicit for Asian elderly people. Little is known about active aging in older Thai adults, and there has been no development of scales to measure the expression of active aging attributes. The aim of this study was to develop a culturally relevant composite scale of active aging for Thai adults (AAS-Thai) and to evaluate its reliability and validity. EIGHT STEPS OF SCALE DEVELOPMENT WERE FOLLOWED: 1) using focus groups and in-depth interviews, 2) gathering input from existing studies, 3) developing preliminary quantitative measures, 4) reviewing for content validity by an expert panel, 5) conducting cognitive interviews, 6) pilot testing, 7) performing a nationwide survey, and 8) testing psychometric properties. In a nationwide survey, 500 subjects were randomly recruited using a stratified sampling technique. Statistical analyses included exploratory factor analysis, item analysis, and measures of internal consistency, concurrent validity, and test-retest reliability. Principal component factor analysis with varimax rotation resulted in a final 36-item scale consisting of seven factors of active aging: 1) being self-reliant, 2) being actively engaged with society, 3) developing spiritual wisdom, 4) building up financial security, 5) maintaining a healthy lifestyle, 6) engaging in active learning, and 7) strengthening family ties to ensure care in later life. These factors explained 69% of the total variance. Cronbach's alpha coefficient for the overall AAS-Thai was 0.95 and varied between 0.81 and 0.91 for the seven subscales. Concurrent validity and test-retest reliability were confirmed. The AAS-Thai demonstrated acceptable overall validity and reliability for measuring the multidimensional attributes of active aging in a Thai context. This newly developed instrument is ready for use as a screening tool to assess active aging levels among older

Taste perception is influenced by several factors. However, the relation between taste perception and food culture is unclear. This study compared taste thresholds between populations with different food culture, i.e. Thai and Japanese. A matched case-control study was conducted in 168 adults (84 for each; aged between 50 and 90 years). The age, sex, systemic disease, medication, smoking, xerostomia, and oral hygiene of both groups were not different. Recognition thresholds (RTs) of sweet, salty, sour, bitter, and umami were measured using filter paper disc (FPD). Detection taste thresholds were measured using electrogustometry. Spicy preference was measured by calibrated questionnaires. Higher RTs of all tastes and higher detection taste thresholds were found in Thai as compared to those of Japanese (P < 0.0001). Separate analyses of healthy and unhealthy persons confirmed the significant differences between 2 countries. The average thresholds for sweet, salty, sour, and bitter in Thai and Japanese were 4 and 2, respectively. The average threshold for umami in Thai and Japanese was 5 and 3, respectively. Moreover, Thai population had stronger preference for spicy food (P < 0.0001) with 70% mild- or moderate and 10% strong lovers, compared to over 90% non- or mild-spicy lovers in Japanese. In addition, 70% of Thai consumed spicy food weekly, whilst 80% of Japanese consumed it monthly. Our findings suggested that population with stronger spicy preference such as Thai had much poorer taste sensitivity and perception than that with milder preference like Japanese. Extensive international survey is needed to conclude the influence of food culture on taste perception. © The Author(s) 2017. Published by Oxford University Press. All rights reserved.

A strong inverse relationship of functional limitation and socioeconomic status has been established in western ageing society. Functional limitation can be related to chronic diseases, disuse, cognitive decline, and ageing. Among chronic diseases in the Thai population, cerebrovascular diseases, diabetes, and arthritis are common. These factors are known to contribute to disability and poor quality of life in the elder population. Neuropsychiatric problems, cognitive decline, dementia, and cultural issues in elderly people also can alter the quality of life of the elderly. The Dementia and Disability Project in Thai Elderly (DDP) aims at comprehensively assessing community dwelling Thai elderly to understand the relationship between disability and motor function, neuropsychiatric symptoms, cognitive function, and chronic diseases. The DDP is the first study to look at the prevalence and etiology of dementia and of mild cognitive impairment (MCI) in Thai elders and to explore the relationship of cognition, disability, small vessel diseases and cortical degeneration with neuroimaging in Thai elderly people. 1998 Thai elders were screened in 2004-2006 and diagnosed as having MCI or dementia. 223 elders with MCI or dementia and cognitively normal elderly had brain magnetic resonance imaging (MRI) or at baseline. 319 elders from the 3 groups had blood tests to investigate the risks and possible etiologies of dementia including genotyping at baseline. The mean age of elders in this study is 69.51(SD=6.71, min=60, max=95) years. 689(34.9%) are men and 1284(65.1%) are women. Mean body weight was 58.36(SD=11.20) kgs. The regression model reveals that performance on gait and balance and serum triglyceride predicts activity of daily living performance (adjusted r2 = 0.280, f=2.644, p=0.003). The majority of abnormal gait in Thai elders was lower level gait disturbance. Only 1.5% (29/1952) had highest level gait disorders. 39.5% of 1964 subjects were free of chronic diseases

Among the people living in the five deep Southern Thai provinces, Thai-Malay Muslims (MUS) constitute the majority, while the remaining are Thai Buddhists (BUD). Cultural, linguistic and religious differences between these two populations have been previously reported. However, their biological relationship has never been investigated. In this study, we aimed to reveal the genetic structure and genetic affinity between MUS and BUD by analyzing 15 autosomal short tandem repeats. Both distance and model-based clustering methods showed significant genetic homogeneity between these two populations, suggesting a common biological ancestry. After Islamization in this region during the fourteenth century AD, gradual albeit nonstatistically significant genetic changes occurred within these two populations. Cultural barriers possibly influenced these genetic changes. MUS have closer admixture to Malaysian-Malay Muslims than BUD countrywide. Admixture proportions also support certain degree of genetic dissimilarity between the two studied populations, as shown by the unequal genetic contribution from Malaysian-Malay Muslims. Cultural transformation and recent minor genetic admixture are the likely processes that shaped the genetic structure of both MUS and BUD.

Exercise has been shown to be effective in cardiovascular endurance in the elderly. We studied the effect of Thai dancing on physical performance of Thai elderly. This was an open-labeled, randomized intervention study. The Thai dancing group exercised for 40 minutes three times a week for 6 weeks. Physical performance ability was the primary outcome, including a 6-minute walk test (6MWT), five-times sit-to-stand (FTSST), and a sit-and-reach test measured before and after 6 weeks of intervention. There were 42 subjects enrolled in the study, and 38 female subjects completed (20 in Thai dance group, 18 controls), with an average age of 65.8 ± 5.1 years. The Thai dance group had significantly better physical performance in all measurements at the end of the study. The 6MWT was longer (416.7 ± 58.7 versus 345.7 ± 55.1 m; P = 0.011), FTSST was quicker (10.2 ± 1.5 versus 14.4 ± 3.3 seconds; P < 0.001), and flexibility was higher (14.9 ± 3.5 versus 11.1 ± 5.7 cm; P = 0.002) in the Thai dance group than the control group. Thai dance can improve physical performance in recently aged (elderly) female adults.

The main purpose of this work was to identify a set of AIMs that stratify the genetic structure and diversity of the Thai population from a high-throughput autosomal genome-wide association study. In this study, more than one million SNPs from the International HapMap database and the Thai depression genome-wide association study have been examined to identify ancestry informative markers (AIMs) that distinguish between Thai populations. An efficient strategy is proposed to identify and characterize such SNPs and to test high-resolution SNP data from international HapMap populations. The best AIMs are identified to stratify the population and to infer genetic ancestry structure. A total of 124 AIMs were clearly clustered geographically across the continent, whereas only 89 AIMs stratified the Thai population from East Asian populations. Finally, a set of 273 AIMs was able to distinguish northern from southern Thai subpopulations. These markers will be of particular value in identifying the ethnic origins in regions where matching by self-reports is unavailable or unreliable, which usually occurs in real forensic cases.

To develop a model of healthy aging from the perspective of Thais, a grounded theory approach, including in-depth interviews and focus groups, was used. A purposive sample of 39 community-dwelling adults aged 40-85 years old was interviewed. The Thai healthy aging model composed of three themes: normality, nature, and dharma. In Thai, they are called tham-ma-da, tham-ma-chat, and tham-ma, or "Thai 3Ts". The theme of normality encompasses subthemes of staying physically active by being involved in plenty of physical activities, and being mentally active with creative and thoughtful hobbies and work. The theme of nature encompasses subthemes of living simply and being careful with money. The theme of dharma encompasses subthemes of enjoyment through helping family and participating in community activities, staying away from stress and worries by talking openly and honestly with someone, making merit, and helping other people without expecting anything in return. A greater understanding of healthy aging is a benefit for older adults and healthcare providers in an intervention-design process. Research can contribute valuable information to shape policy for healthy aging as well. © 2013 Wiley Publishing Asia Pty Ltd.

To develop a Thai version of the Kujala score and show the evaluation of the validity and reliability of the score. The Thai version of the Kujala score was developed using the forward-backward translation protocol. The 49 PFPS patients answered the Thai version of questionnaires including the Kujala score, Short Form-36 (SF-36) and International Knee Documentation Committee (IKDC) Subjective Knee Form. The validity between the scores has been tested. The reliability was assessed using test-retest reliability and internal consistency. The Thai version of the Kujala score showed a good correlation with Thai IKDC Subjective Knee Form (Pearson's correlation coefficient; r = 0.74: p < 0.01) and moderate correlation with the Thai SF-36 subscales of physical component summary, total score and role physical (r = 0.586, 0.571 and 0.524, respectively: p < 0.01). The test-retest reliability was excellent with an intra-class correlation coefficient of 0.908 (p < 0.001; 95% CI [0.842-0.947]). The internal consistency was strong with Cronbach's alpha of 0.952 (p < 0.001). No floor and ceiling effects were observed. The Thai version of the Kujala score has shown good validity and reliability. This score can be effectively used for evaluating Thai patients with patellofemoral pain syndrome. Implications for Rehabilitation The Kujala score is a self-administered questionnaire for patients with patellofemoral pain syndrome (PFPS). The validity and reliability of the Thai version of Kujala are compatible with other versions (Turkish, Chinese and Persian version). The Thai version of Kujala has been shown to have validity and reliability in Thai PFPS patients and can be used for clinical evaluation and also in the research work.

"Quality of life" has become a main focus of interest in medicine. The Pictorial Thai Quality of Life (PTQL) was developed in order to measure the Thai mental illness both in a clinical setting and community. The purpose of this study was to develop the Pictorial Thai Quality of Life (PTQL), having adequate and sufficient construct validity, discriminant power, concurrent validity, and reliability. To develop the Pictorial Thai Quality of Life Test, two samples groups were used in the present study: (1) pilot study samples: 30 samples and (2) survey samples were 672 samples consisting of normal, and psychiatric patients. The developing tests items were collected from a review of the literature in which all the items were based on the WHO definition of Quality of Life. Then, experts judgment by the Delphi technique was used in the first stage. After that a pilot study was used to evaluate the testing administration, and wording of the tests items. The final stage was collected data from the survey samples. The results of the present study showed that the final test was composed 25 items. The construct validity of this test consists of six domains: Physical, Cognitive, Affective, Social Function, Economic and Self-Esteem. All the PTQL items have sufficient discriminant power It was found to be statistically significant different at the. 001 level between those people with mental disorders and normal people. There was a high level of concurrent validity association with WHOQOL-BREF, Pearson correlation coefficient and Area under ROC curve were 0.92 and 0.97 respectively.

To describe the experience of postpartum care among Thai women in Melbourne, Australia. Ethnographic interviews and participant observation with women in relation to postpartum care and practices. Melbourne Metropolitan Area, Victoria, Australia. 26 Thai born women who gave birth in Australia. The Thai women had varying views about the length of time they should spend in hospital and the care they received. Ten of the twelve women who had had a caesarean birth stayed in hospital for six or more days, consistent with the hospital practice. However, most of those who had had a vaginal delivery opted to go home earlier than the standard hospital practice of four days stay. This was because they were unhappy about specific hospital practices, the hospital environment, or because there are several Thai confinement customs, which, traditionally, a new mother must observe in order to maintain good health and avoid future ill health and which they were not able to follow in hospital. Nevertheless, most women were satisfied with their postpartum care. Most women were aware of the Thai cultural beliefs and practices. However, they showed varying ways of coping with the hospital environment in relation to their varying social situations. Thai women are diverse in their needs, perceptions and experience of postpartum care. Therefore, it is appropriate neither to stereotype all Thai women as requiring to follow traditional confinement practices nor to require them to adjust to standard hospital practices. Rather an environment of caring concern whereby each woman's individual needs can be solicited, understood and, where possible, attended to as required. The challenge is in achieving this.

To assess the construct validity of the Thai EuroQoL (EQ-5D) among an occupational population in Thailand. Data were derived from a large cohort study among employees of the Electricity Generating Authority of Thailand. In 2008 and 2009, 4,850 participants completed the Thai EQ-5D and Short-Form 36 version 2 (SF-36v2). Thai preferences weights were used to convert EQ-5D health states into EQ-5D index scores. Construct validity of the Thai EQ-5D was examined by specifying and testing hypotheses about the relationships between the EQ-5D, SF-36v2, and participants' demographic and medical characteristics. Construct validity of the Thai EQ-5D was supported by expected relationships with SF-36v2 scale and summary scores. For example, SF-36v2 scores on the mental health scale were much lower for participants who reported having problems on the EQ-5D anxiety/depression dimension compared to those reporting no problems (mean norm-based SF-36v2 scores: 52.9 vs. 41.8, p < 0.001). Additionally, reporting a problem in a given EQ-5D dimension was generally associated with lower SF-36v2 summary scores. The EQ-5D index score distinguished between groups of participants in the expected manner, on the basis of sex, age, education and self-reported health, thus providing evidence of known-groups validity. The study demonstrated good construct validity of the Thai EQ-5D in a large occupational population in Thailand.

Ethnic and racial differences in infant skin have not been well characterized. The purpose of this study was to establish whether there are ethnic differences and similarities in the stratum corneum (SC) functions of Thai and Chinese infants. Healthy infants 6 to 24 months of age (N = 60; 30 Thai, 30 Chinese) who resided in Bangkok, Thailand, were enrolled. Transepidermal water loss (TEWL) and SC hydration (capacitance) on the thigh, buttock, and upper arm were measured. Ceramide content was determined in the SC on the upper arm. SC hydration was not remarkably different between the two ethnicities at any site measured, but TEWL was significantly higher in Chinese infants than in Thai infants at all sites. Hydration of the SC was not significantly correlated with age in either ethnicity. TEWL had significant but weak correlations with age on the thigh and upper arm in Thai infants. Ceramide content was significantly higher in Chinese SC than in Thai SC. No relationship between ceramide content and TEWL or hydration was observed in either ethnicity. The significant differences in TEWL and ceramide contents between Chinese and Thai infant skin could prove useful in designing skin care and diapering products that are best suited for each ethnicity. © 2017 Wiley Periodicals, Inc.

Synthesis of Polysyllabic Sequences of Thai Tones Using a Generative Model of Fundamental Frequency Contours

NASA Astrophysics Data System (ADS)

Seresangtakul, Pusadee; Takara, Tomio

In this paper, the distinctive tones of Thai in running speech are studied. We present rules to synthesize F0 contours of Thai tones in running speech by using the generative model of F0 contours. Along with our method, the pitch contours of Thai polysyllabic words, both disyllabic and trisyllabic words, were analyzed. The coarticulation effect of Thai tones in running speech were found. Based on the analysis of the polysyllabic words using this model, rules are derived and applied to synthesize Thai polysyllabic tone sequences. We performed listening tests to evaluate intelligibility of the rules for Thai tones generation. The average intelligibility scores became 98.8%, and 96.6% for disyllabic and trisyllabic words, respectively. From these result, the rule of the tones' generation was shown to be effective. Furthermore, we constructed the connecting rules to synthesize suprasegmental F0 contours using the trisyllable training rules' parameters. The parameters of the first, the third, and the second syllables were selected and assigned to the initial, the ending, and the remaining syllables in a sentence, respectively. Even such a simple rule, the synthesized phrases/senetences were completely identified in listening tests. The MOSs (Mean Opinion Score) was 3.50 while the original and analysis/synthesis samples were 4.82 and 3.59, respectively.

This predictive correlational study was designed to test a comprehensive model of depression for Thai adolescents. This sample included 800 high school students in Chiang Mai, Thailand. Data were collected using self-reported measures of depression, negative automatic thoughts, effective social problem solving, ineffective social problem solving, rumination, parental care, parental overprotection, and negative life events. Structural equation modeling revealed that negative automatic thoughts, effective and ineffective social problem solving mediated the effects of rumination, negative life events, and parental care and overprotection on adolescent depression. These findings provide new knowledge about identified factors and the mechanisms of their influence on depression among Thai adolescents, which are appropriate for targeting preventive interventions. © 2012 Wiley Periodicals, Inc.

In this qualitative study, we provide an in-depth understanding of the views of healthy aging among Thai elderly and explore the ways that contribute to healthy aging. Data were collected using focus groups and in-depth interviews in four selected provinces of Thailand, and were analyzed using content analysis. The results revealed that Thai elderly described being healthy as the result of multiple components involving physical, mental, and social well-being. Healthy aging was viewed as an absence of serious diseases, having functional independence, a positive psycho-emotional outlook, and making a social contribution. The factors considered to contribute to healthy aging included activities promoting physical and psychological health, as well as active engagement in social activities. Understanding how the elderly define healthy aging and identifying the most important components and factors that contribute to being healthy provides insight into possible policy implications and interventions to promote health and well-being among Thai elderly. © 2012 Wiley Publishing Asia Pty Ltd.

The impact of climate change is estimated to be particularly severe in Thailand. Overall, the country faces an increase in surface temperatures, severe storms and floods, and a possible increase in the number of mass disasters in the region. It is extremely important that forensic scientists have access to sex estimation methods developed for use on a Thai population. The goal of this project is to evaluate the accuracy of sex estimation discriminant functions, created using contemporary Mexican and Greek populations, when applied to a contemporary Thai sample. The length of the glenoid cavity (LGC) and breadth of the glenoid cavity (BGC) were measured. The sample included 191 individuals (95 males and 96 females) with age ranges from 19 to 96years old. Overall, when the Mexican and Greek discriminant functions were applied to the Thai sample they showed higher accuracy rates for sexing female scapulae (83% to 99%) than for sexing male scapulae (53% to 92%). Size comparisons were made to Chilean, Mexican, Guatemalan, White American, and Greek populations. Overall, in males and females of the Thai sample, the scapulae were smaller than in the Chilean, Mexican, White American, and Greek populations. However, the male and female Thai scapulae were larger than in the Guatemalan sample. Population-specific discriminant functions were created for the Thai population with an overall sex classification accuracy rate of 83% to 88%.

In total 462 participants were recruited - 310 medical students from Chiang Mai University and 152 psychiatric patients, and they completed the Thai version of the MSPSS, the State Trait Anxiety Inventory (STAI), the Rosenberg Self-Esteem Scale (RSES) and the Thai Depression Inventory (TDI). Test-retest reliability was conducted over a four week period. Factor analysis produced three-factor solutions for both patient (PG) and student groups (SG), and overall the model demonstrated adequate fit indices. The mean total score and the sub-scale score for the SG were statistically higher than those in the PG, except for 'Significant Others'. The internal consistency of the scale was good, with a Cronbach's alpha of 0.91 for the SG and 0.87 for the PG. After a four week retest for reliability exercise, the intra-class correlation coefficient (ICC) was found to be 0.84. The Thai-MSPSS was found to have a negative correlation with the STAI and the TDI, but was positively correlated with the RSES. The Thai MSPSS is a reliable and valid instrument to use.

This study aims to investigate the elemental compositions in 93 Thai rice samples using instrumental neutron activation analysis (INAA) and to identify rice according to their types and rice cultivars using statistical analysis. As, Mg, Cl, Al, Br, Mn, K, Rb and Zn in Thai jasmine rice and Sung Yod rice samples were successfully determined by INAA. The accuracy and precision of the INAA method were verified by SRM 1568a Rice Flour. All elements were found to be in a good agreement with the certified values. The precisions in term of %RSD were lower than 7%. The LODs were obtained in range of 0.01 to 29 mg kg-1. The concentration of 9 elements distributed in Thai rice samples was evaluated and used as chemical indicators to identify the type of rice samples. The result found that Mg, Cl, As, Br, Mn, K, Rb, and Zn concentrations in Thai jasmine rice samples are significantly different but there was no evidence that Al is significantly different from concentration in Sung Yod rice samples at 95% confidence interval. Our results may provide preliminary information for discrimination of rice samples and may be useful database of Thai rice.

The main purpose of this work was to identify a set of AIMs that stratify the genetic structure and diversity of the Thai population from a high-throughput autosomal genome-wide association study. In this study, more than one million SNPs from the international HapMap database and the Thai depression genome-wide association study have been examined to identify ancestry informative markers (AIMs) that distinguish between Thai populations. An efficient strategy is proposed to identify and characterize such SNPs and to test high-resolution SNP data from international HapMap populations. The best AIMs are identified to stratify the population and to infer genetic ancestry structure. A total of 124 AIMs were clearly clustered geographically across the continent, whereas only 89 AIMs stratified the Thai population from East Asian populations. Finally, a set of 273 AIMs was able to distinguish northern from southern Thai subpopulations. These markers will be of particular value in identifying the ethnic origins in regions where matching by self-reports is unavailable or unreliable, which usually occurs in real forensic cases.

Background Peripheral neuropathy is the most common complications of diabetic patients and leads to loss of plantar cutaneous sensation, movement perception, and body balance. Thai foot massage is an alternative therapy to improve balance. Therefore, the purpose of this study was to investigate the effects of Thai foot massage on balance performance in diabetic patients with peripheral neuropathy. Material/Methods Sixty patients with type-2 diabetes were recruited and randomly assigned into either the Thai foot massage or control groups. The Thai foot massage group received a modified Thai traditional foot massage for 30 min, 3 days per week for 2 weeks. We measured timed up and go (TUG), one leg stance: OLS), the range of motion (ROM) of the foot, and foot sensation (SWMT) before treatment, after the first single session, and after the 2-week treatment. Results After the single treatment session, only the Thai foot massage group showed a significant improvement in TUG. After the 2-week treatment, both Thai foot massage and control groups showed a significant improvement of TUG and OLS (P<0.05); however, when comparing between 2 groups, the Thai foot massage group showed better improvement in TUG than the control group (p<0.05). The Thai foot massage group also showed significant improvements in ROM and SWMT after the 2-week treatment. Conclusions The results of this study suggest that Thai foot massage is a viable alternative treatment for balance performance, ROM of the foot, and the foot sensation in diabetic patients with peripheral neuropathy.

Cervical cancer is the most common cancer in women, and ranks seventh of all cancers worldwide, with 529000 cases in 2008 and more than 85% cases occur in developing countries. One way to treat this cancer is through the inhibition of HDAC enzymes which play a strategic role in the regulation of gene expression. Suberoyl Anilide Hydroxamic Acid (SAHA) or Vorinostat is a drug which commercially available to treat the cancer, but still has some side effects. This research present in silico SAHA modification in Zinc Binding Group (ZBG) by organoselenium compound to get ligands which less side effect. From molecular docking simulation, and interaction analysis, there are five best ligands, namely CC27, HA27, HB28, IB25, and KA7. These five ligands have better binding affinity than the standards, and also have interaction with Zn2+ cofactor of inhibited HDAC enzymes. This research is expected to produce more potent HDAC inhibitor as novel drug for cervical cancer treatment.

Reflection of Confucianism, Hinduism, and Buddhism on gender relations and gender specific occupation in Thai society.

Shrestha, M; Weber, K E

It is posited that present-day Thai society is the product of different settlement patterns among Chinese Confucian followers and those ascribing to matrilocal practices. Chinese settled in urban areas and maintained Confucian dogma that barred women from high ranking positions and dictated a women's role of subservience to men. Matrilocal systems proliferated in rural areas. The village kinship system was egalitarian, until a class-state society was instituted and patriarchal systems dominated. At that time, women's status was reduced. Massive Chinese immigration occurred during the mid-19th century until World War II. Some Indians also migrated during this time period. The dominant use of the Thai language forced the Chinese to assimilate into Thai culture. Thai Buddhist practices were open and similar enough to Confucian ideology that religious assimilation also occurred. A small group of Chinese immigrants retained their ties to Chinese customs. The pattern of foreigners' involvement in the Thai economy was promoted by official policy. In the last several decades Thai policy shifted to an increasingly Thai-influenced economy. Other influences on gender patterns and Thai culture were the Hinduism of Indians who settled in Central Siam, the Mon aristocracy, and Brahmin cults. After the Khmers took over control of this region, the Indian caste system and the Hindu belief in Manu were integrated into Khmer culture. Women were considered the weaker and inferior sex and dependent upon men. The kings of Siam followed Brahmin rituals after the 15th century. Buddhism and the "sangha" became the central Thai religious institution. Even today Buddhist monks are given 3 months time off with pay for time spent as a monk, while maternity leave for women is limited to 45 days. The status of women is traced during the Sukothai period (1250-1350), the Ayudhaya period (1350-1767), and the Ratanakosin period (since 1782). Present occupational patterns reflect women's dominance in

Since anesthesia, unlike medical or surgical specialties, does not constitute treatment, The Royal College of Anesthesiologists of Thailand host the Thai Anesthesia Incidents Study (THAI Study) of anesthetic outcomes to determine factors related to anesthesia related adverse events. A prospective descriptive study of occurrence screening was conducted in 20 hospitals comprised of 7 university, 4 general and 4 district hospitals across Thailand. Anesthesia personnels were required to fill up patient-related, surgical-related, anesthesia-related variables and adverse outcomes on a strutured data entry form. The data included preanesthetic evaluation intraoperative period and 24 hr postoperative period. Adverse events specific form was recorded when adverse events occurred. All data were keyed in data management unit with double entry technique and descriptive statistics was used in the first phase of this study. A total of 163403 consecutive cases were recorded in one year. The mean (S.D.) of age, weight and height of patients were 38.6(2.3) yrs, 53.9(17.7) kgs and 153.4(22.7) cm respectively. There were more female (52.9%) than male (47. 1%) patients with ASA PS 1, 2, 3, 4, 5 = 50.8%, 36.3%, 10.7%, 2.0%, 0.2% respectively. Hypertension (11.6%), anemia (7.7%) and diabetes melitus (6.8%) were the three most common abnormalities in preanesthetic history taking. Mallampati score of 111870 patients grade 1, 2, 3, 4 were 54.0%, 39.7%, 5.6%, 0.7% and laryngoscopic grade 1, 2, 3, 4 of 74888 patients were 81.0%, 15.5%, 3.0% and 0.5% respectively. The first phase of THAI study epidemiological project can represent both the anesthesia and surgical profiles in Thailand. The collected data available should be useful for the improvement of the quality of anesthesia, guidelines for clinical practices, medical education and for further research.

Cardiopulmonary monitoring (CPM) is rapidly progressing but data regarding CPM in Thai ICUs was unavailable. The objective of this study was to describe the situation, and gaps of CPM in Thai ICUs. Data were retrieved from the ICU-RESOURCE I study database survey CPM was divided into two aspects of device and measurement methods. These were categorized by device availability grading (AG), device availability per bed (DPB) and numeric frequency grading scale (FGS). Device availability was compared between academic and non-academic ICUs. Gap analysis of DPB and FGS was performed. Statistical significant difference was defined as p-value < 0.05. One hundred and fifty-five ICUs across Thailand participated in this study. Academic ICUs had significantly more devices available in new equipment with p < 0.05 (Vigilio, PiCCO, NICOM, esophageal pressure monitoring, transcutaneous PO2, electrical impedance tomography of lung) as well as measurement methods (stroke volume variation [SVV], pulse pressure variation [PPC], central venous oxygen saturation [ScvO2], lung mechanics). Most of new and higher technological devices had low density and few were available in all of Thai ICUs. However, in gap analysis, although these new devices and measurement techniques were available in ICUs, they were not frequently utilized. New technology devices of CPM had more availability in ACAD than in non-ACAD ICUs. Formal continuous training in new measurement methods should be established for reducing the availability and utilization gap (Thai Clinical Trial Registry: TCTR-201200005).

A single-wavelength spectral-imaging-based Thai jasmine rice breed identification is demonstrated. Our nondestructive identification approach relies on a combination of fluorescent imaging and simple image processing techniques. Especially, we apply simple image thresholding, blob filtering, and image subtracting processes to either a 545 or a 575nm image in order to identify our desired Thai jasmine rice breed from others. Other key advantages include no waste product and fast identification time. In our demonstration, UVC light is used as our exciting light, a liquid crystal tunable optical filter is used as our wavelength seclector, and a digital camera with 640activepixels×480activepixels is used to capture the desired spectral image. Eight Thai rice breeds having similar size and shape are tested. Our experimental proof of concept shows that by suitably applying image thresholding, blob filtering, and image subtracting processes to the selected fluorescent image, the Thai jasmine rice breed can be identified with measured false acceptance rates of <22.9% and <25.7% for spectral images at 545 and 575nm wavelengths, respectively. A measured fast identification time is 25ms, showing high potential for real-time applications.

To validate the Thai language version of the Psoriasis Epidemiology Screening Tool (PEST) and the Early Arthritis for Psoriatic Patients Questionnaire (EARP), as well as also to develop a new tool for screening psoriatic arthritis (PsA) among psoriasis (Ps) patients. This was a cross-sectional study. Ps patients visiting the psoriasis clinic at Siriraj Hospital were recruited. They completed the EARP and PEST. Full musculoskeletal history, examination, and radiography were evaluated. PsA was diagnosed by a rheumatologist's evaluation and fulfillment of the classification criteria for psoriatic arthritis. Receiver operator characteristic (ROC) curves, sensitivity, and specificity were used to evaluate the performances of the tools. The Siriraj Psoriatic Arthritis Screening Tool (SiPAT) contained questions most relevant to peripheral arthritis, axial inflammation, and enthesitis, selected from multivariate analysis. Of a total of 159 patients, the prevalence of PsA was 78.6 %. The ROC curve analyses of Thai EARP, PEST, and SiPAT were 0.90 (95 % CI 0.84, 0.96), 0.85 (0.78, 0.92), and 0.89 (0.83, 0.95), respectively. The sensitivities of SiPAT, Thai EARP, and PEST were 91.0, 83.0, and 72.0 %, respectively, while the specificities were 69.0, 79.3, and 89.7 %, respectively. All screening questionnaires showed good diagnostic performances. SiPAT could be considered as a screening tool with its desirable properties: higher sensitivity and taking less time. Thai PEST and EARP could possibly be sequentially administered for people with a positive test from SiPAT to reduce the number of false positives.

There is considerable ethno-linguistic and genetic variation among human populations in Asia, although tracing the origins of this diversity is complicated by migration events. Thailand is at the center of Mainland Southeast Asia (MSEA), a region within Asia that has not been extensively studied. Genetic substructure may exist in the Thai population, since waves of migration from southern China throughout its recent history may have contributed to substantial gene flow. Autosomal SNP data were collated for 438,503 markers from 992 Thai individuals. Using the available self-reported regional origin, four Thai subpopulations genetically distinct from each other and from other Asian populations were resolved by Neighbor-Joining analysis using a 41,569 marker subset. Using an independent Principal Components-based unsupervised clustering approach, four major MSEA subpopulations were resolved in which regional bias was apparent. A major ancestry component was common to these MSEA subpopulations and distinguishes them from other Asian subpopulations. On the other hand, these MSEA subpopulations were admixed with other ancestries, in particular one shared with Chinese. Subpopulation clustering using only Thai individuals and the complete marker set resolved four subpopulations, which are distributed differently across Thailand. A Sino-Thai subpopulation was concentrated in the Central region of Thailand, although this constituted a minority in an otherwise diverse region. Among the most highly differentiated markers which distinguish the Thai subpopulations, several map to regions known to affect phenotypic traits such as skin pigmentation and susceptibility to common diseases. The subpopulation patterns elucidated have important implications for evolutionary and medical genetics. The subpopulation structure within Thailand may reflect the contributions of different migrants throughout the history of MSEA. The information will also be important for genetic association

Research on happiness has been of interest in many parts of the world. Here we provide evidence from developing countries; this is the first analysis of happiness among a cohort of Thai distance learning adults residing throughout the country (n = 60,569 in 2009). To measure happiness, we tested use of the short format Thai Mental Health Indicators (TMHI), correlating each domain with two direct measures of happiness and life satisfaction. Several TMHI domains correlated strongly with happiness. We found the mental state and the social support domains moderately or strongly correlated with happiness by either measure (correlation coefficients 0.24-0.56). The other two TMHI domains (mental capacity and mental quality) were not correlated with happiness. Analysis of socio-demographic attributes and happiness revealed little effect of age and sex but marital status (divorced or widowed), low household income, and no paid work all had strong adverse effects. Our findings provide Thai benchmarks for measuring happiness and associated socio-demographic attributes. We also provide evidence that the TMHI can measure happiness in the Thai population. Furthermore, the results among Thai cohort members can be monitored over time and could be useful for comparison with other Southeast Asian countries.

To analyze the clinical course, outcome, contributing factors and factors minimizing the incidents of perioperative myocardial ischemia or infarction (PMI) from Thai AIMS study. The present study was a prospective multicenter study. Data was collected from 51 hospitals in Thailand during a six-month period. The participating anesthesia provider completed the standardized incident report form of the Thai AIMS as soon as they found the PMI incident. Each incident was reviewed by three peer reviewers for clinical courses, contributing factors, outcome and minimizing factors of PMI. From the Thai AIMS incident report, the authors found 25 suspected PMI cases which was 0.9% of the 2,669 incidents reported in the present study. Most of the PMI occurred in elective cases (84%) and orthopedic procedures (56%). The majority of PMI was reported from the patients undergoing general anesthesia (72%). Suspected PMI occurred mostly during operations (56%). New ST-T segment change was detected in 92% of these patients. The most common immediate outcome of PMI was major physiological change (88%). The most common management effect of PMI was unplanned ICU admission (64%); the others were prolonged ventilatory support (12%) and prolonged hospital stay (16%). Four patients (16%) died after the suspected PMI. Most of the events occurred spontaneously and were unpreventable (80%). Patient factors (100%), anesthesia factors (72%), surgical factors (32%) and system factors (8%) were all judged as a precipitating factor for PMI. Human factors were the most common contributing factors which included poor preoperative evaluation, inexperience and improper decision. The three most common factors minimizing the adverse incidents included prior experienced, high awareness and experienced assistance. The recommended corrective strategies were guideline practice, quality assurance activity, improvement of supervision and additional training. Perioperative myocardial ischemia/infarction was

HOOS was developed as an extension of the Western Ontario and McMaster Universities' Osteoarthritis Index questionnaire for measuring symptoms and functional limitations related to the hip(s) of patients with osteoarthritis. To determine the validity and reliability of the Thai version of the Hip disability and Osteoarthritis Outcome Score (HOOS) vis-à-vis hip osteoarthritis, the original HOOS was translated into a Thai version of HOOS, according to international recommendations. Patients with hip osteoarthritis (n = 57; 25 males) were asked to complete the Thai version of HOOS twice: once then again after a 3-week interval. The test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Internal consistencies were analyzed using Cronbach's alpha, while the construct validity was tested by comparing the Thai HOOS with the Thai modified SF-36 and calculating the Spearman's rank correlation coefficients. The Thai HOOS produced good reliability (i.e., the ICC was greater than 0.9 in all five subscales). All of the Cronbach's alpha showed that the Thai HOOS had high internal consistency (Cronbach's alpha greater than 0.8), especially for the pain and ADL subscales (0.89 and 0.90, respectively). The Spearman's rank correlation for all five subscales of the Thai HOOS had moderate correlation with the Bodily Pain subscale of the Thai SF-36. The pain subscale of the Thai HOOS had a high correlation with the Vitality and Social Function subscales of the Thai SF-36 (r = 0.55 and 0.54)-with which the symptom subscale had a moderate correlation. The Thai version of HOOS had excellent internal consistency, excellent test-retest reliability, and good construct validity. It can be used as a reliable tool for assessing quality of life for patients with hip osteoarthritis in Thailand.

Pain management is a core nursing function, and it plays a key role in postoperative care. It is important to understand the cultural context of nursing practices and how this affects effective pain management. The aim of this study was to describe the professional and cultural framework within which pain management is practiced on a Thai surgical ward. Spradley's ethnographic methodology was used. Data were collected through 98.5 hours of field observations and interviews at a surgical ward in Thailand. Three themes were constructed that describe the way Thai nurses practiced pain management: (i) complex communications system to address pain and to respond to it, (ii) the essence of Thai-ness, and (iii) a passive approach to pain management. The results indicate that, in the response to discomfort and pain, better pain management will result if there is a shift from functional to patient-centered care. The nursing culture needs to be further researched and discussed, in order to set priorities in line with the goals of national and international organizations for improving postoperative care and promoting patient comfort.

Analysis of the influence of the heat transfer phenomena on the late phase of the ThAI Iod-12 test

Iodine is one of the major contributors to the source term during a severe accident in a Nuclear Power Plant for its volatility and high radiological consequences. Therefore, large efforts have been made to describe the Iodine behaviour during an accident, especially in the containment system. Due to the lack of experimental data, in the last years many attempts were carried out to fill the gaps on the knowledge of Iodine behaviour. In this framework, two tests (ThAI Iod-11 and Iod-12) were carried out inside a multi-compartment steel vessel. A quite complex transient characterizes these two tests; therefore they are also suitable for thermal- hydraulic benchmarks. The two tests were originally released for a benchmark exercise during the SARNET2 EU Project. At the end of this benchmark a report covering the main findings was issued, stating that the common codes employed in SA studies were able to simulate the tests but with large discrepancies. The present work is then related to the application of the new versions of ASTEC and MELCOR codes with the aim of carry out a new code-to-code comparison vs. ThAI Iod-12 experimental data, focusing on the influence of the heat exchanges with the outer environment, which seems to be one of the most challenging issues to cope with.

The number of Thai tourists visiting India is increasing each year. Most studies investigating health problems among international travellers to India have focused on travellers from Europe or North America, and the applicability of these studies to Asian travellers is unknown. This cross-sectional study used data collected from Thai tourists who had recently completed a trip to India. A questionnaire on demographic data, travel characteristics, pre-travel health preparation, and health problems during the trip to India was administered. All participants were also invited to answer a follow-up questionnaire 15 days after their arrival. The study included 1,304 Thai tourists returning from India between October 2014 and March 2015. Sixty-two percent were female. Overall median age was 49 years, and the median length of stay was 10.6 days. Most were package tourists, and 52% (675) reported health problems during their trip. Common health problems were cough, runny nose, and sore throat (31.1%), followed by musculoskeletal problems (21.7%), fever (12.7%), diarrhea (9.8%) and skin problems (6.6%). Other reported problems were related to the eyes/ears (2.1%), animal exposure (1.9%) and accidents (0.8%). We found that several factors may be associated with the incidence of health problems among these tourists, including travelling style and travel health preparation. In the follow-up questionnaire, 16.8% of the participants reported new or additional symptoms that developed after their return to Thailand. Respiratory symptoms were still the most common health problems during this 15-day period. Over half (52%) of Thai tourists experienced health problems during their trip to India. The most common health problem was not travellers' diarrhoea, as would be expected from published studies. Rather, respiratory and musculoskeletal problems were common symptoms. This information will be useful in pre-travel assessment and care. Our findings may indicate that health risks among

To develop a scale for measuring refractive error quality of life (QOL) for Thai adults. The full survey comprised 424 respondents from 5 medical centers in Bangkok and from 3 medical centers in Chiangmai, Songkla and KhonKaen provinces. Participants were emmetropes and persons with refractive correction with visual acuity of 20/30 or better An item reduction process was employed by combining 3 methods-expert opinion, impact method and item-total correlation methods. The classical reliability testing and the validity testing including convergent, discriminative and construct validity was performed. The developed questionnaire comprised 87 items in 6 dimensions: 1) quality of vision, 2) visual function, 3) social function, 4) psychological function, 5) symptoms and 6) refractive correction problems. It is the 5-level Likert scale type. The Cronbach's Alpha coefficients of its dimensions ranged from 0.756 to 0. 979. All validity testing were shown to be valid. The construct validity was validated by the confirmatory factor analysis. A short version questionnaire comprised 48 items with good reliability and validity was also developed. This is the first validated instrument for measuring refractive error quality of life for Thai adults that was developed with strong research methodology and large sample size.

Superstitious Beliefs and Problem Gambling Among Thai Lottery Gamblers: The Mediation Effects of Number Search and Gambling Intensity.

Pravichai, Sunisa; Ariyabuddhiphongs, Vanchai

2015-12-01

Thai lottery gamblers won prizes after betting on numbers they obtained from newspaper stories. We hypothesized that Thai lottery gamblers' superstitious beliefs were related to their problem gambling through the mediation of number search and gambling intensity. In a study among 380 Thai lottery gamblers, superstitious beliefs were operationally defined as the beliefs in events or objects that seemed to reveal numbers, number search as an attempt to identify numbers to bet, gambling intensity as the frequency and amounts of lottery gambling, and problem gambling as the symptoms of problems relating to lottery gambling. Results support the hypotheses. There is a statistically significant indirect relationship between Thai lottery gamblers' superstitious beliefs and their problem gambling through the mediation of number search and gambling intensity. Thai lottery gamblers need to be reminded that their superstitious beliefs and number search are precursors of their problem gambling.

Local Thai and imported Malaysian beef in southern Thailand area carry several Shiga toxin-producing Escherichia coli (STEC) serotypes. STEC O104 is an important pathogen capable of causing outbreaks with considerable morbidity and mortality. This study investigated the presence of E. coli O104 from local Thai and imported Malaysian beef obtained from markets in Hat Yai City, Songkhla Province during August 2015 - February 2016. Thirty-one E. coli O104 strains were isolated from 12 beef samples (16% and 23% Thai and imported Malaysian, respectively). Thirty strains possessed aggA (coding for a major component of AAF/I fimbriae), a gene associated with enteroaggregative E. coli (EAEC) pathotype, and all strains carried fimH (encoding Type 1 fimbriae). Thirty strains belonged to phylogenetic group B1 and one strain (from Malaysian beef) to group A. Agglutination of yeast cells was observed among 29 E. coli O104 strains. Investigation of stx2 phage occupancy loci demonstrated that sbcB was occupied in 12 strains. Antimicrobial susceptibility assay revealed that 7 strains were resistant to at least one antimicrobial agent and two were multi-drug resistant. One strain carried extended spectrum β-lactamase gene blaCTX-M and three carried blaTEM. PFGE-generated DNA profiling showed identical DNA pattern between that of one EAEC O104 strain from Thai beef and another from Malaysian beef, indicating that these two strains originated from the same clone. This is the first report in Thailand describing the presence of EAEC O104 from both Thai and imported Malaysian beef and their transfer between both countries. Thorough surveillance of this pathogen in fresh meats and vegetables should help to prevent any possible outbreak of E. coli O104.

Self-administered questionnaires have become an important aspect for clinical outcome assessment of foot and ankle-related problems. The Foot and Ankle Ability Measure (FAAM) subjective form is a region-specific questionnaire that is widely used and has sufficient validity and reliability from previous studies. Translate the original English version of FAAM into a Thai version and evaluate the validity and reliability of Thai FAAM in patients with foot and ankle-related problems. The FAAM subjective form was translated into Thai using forward-backward translation protocol. Afterward, reliability and validity were tested. Following responses from 60 consecutive patients on two questionnaires, the Thai FAAM subjective form and the short form (SF)-36, were used. The validity was tested by correlating the scores from both questionnaires. The reliability was adopted by measuring the test-retest reliability and internal consistency. Thai FAAM score including activity of daily life (ADL) and Sport subscale demonstrated the sufficient correlations with physical functioning (PF) and physical composite score (PCS) domains of the SF-36 (statistically significant with p < 0.001 level and ≥ 0.5 values). The result of reliability revealed highly intra-class correlation coefficient as 0.8 and 0.77, respectively from test-retest study. The internal consistency was strong (Cronbach alpha = 0.94 and 0.88, respectively). The Thai version of FAAM subjective form retained the characteristics of the original version and has proved a reliable evaluation instrument for patients with foot and ankle-related problems.

Forensic Applicability of Femur Subtrochanteric Shape to Ancestry Assessment in Thai and White American Males.

Tallman, Sean D; Winburn, Allysha P

2015-09-01

Ancestry assessment from the postcranial skeleton presents a significant challenge to forensic anthropologists. However, metric dimensions of the femur subtrochanteric region are believed to distinguish between individuals of Asian and non-Asian descent. This study tests the discriminatory power of subtrochanteric shape using modern samples of 128 Thai and 77 White American males. Results indicate that the samples' platymeric index distributions are significantly different (p≤0.001), with the Thai platymeric index range generally lower and the White American range generally higher. While the application of ancestry assessment methods developed from Native American subtrochanteric data results in low correct classification rates for the Thai sample (50.8-57.8%), adapting these methods to the current samples leads to better classification. The Thai data may be more useful in forensic analysis than previously published subtrochanteric data derived from Native American samples. Adapting methods to include appropriate geographic and contemporaneous populations increases the accuracy of femur subtrochanteric ancestry methods. © 2015 American Academy of Forensic Sciences.

This study was conducted to determine and compare the kinematics of knee strike in MuayThai between dominant and non-dominant lower limb. Ten MuayThai beginners (mean age = 20 ± 1 years old) with less than one week experiences in MuayThai training were recruited and were asked to perform three trials of knee strikes for each leg (dominant and non-dominant). Joint angles and angular velocity of the movement were assessed for each trial. Repeated measure multivariate analyses of variances (MANOVA) were performed to compare the kinematics data between the dominant and non-dominant lower limb. Results showed no significant differences existed in all the joint kinematics examined between dominant and non-dominant lower limb. As the conclusion, MuayThai beginners demonstrated no differences of joint kinematics during knee strike between dominant and non-dominant lower limb.

Discovery of Predicate-Oriented Relations among Named Entities Extracted from Thai Texts

NASA Astrophysics Data System (ADS)

Tongtep, Nattapong; Theeramunkong, Thanaruk

Extracting named entities (NEs) and their relations is more difficult in Thai than in other languages due to several Thai specific characteristics, including no explicit boundaries for words, phrases and sentences; few case markers and modifier clues; high ambiguity in compound words and serial verbs; and flexible word orders. Unlike most previous works which focused on NE relations of specific actions, such as work_for, live_in, located_in, and kill, this paper proposes more general types of NE relations, called predicate-oriented relation (PoR), where an extracted action part (verb) is used as a core component to associate related named entities extracted from Thai Texts. Lacking a practical parser for the Thai language, we present three types of surface features, i.e. punctuation marks (such as token spaces), entity types and the number of entities and then apply five alternative commonly used learning schemes to investigate their performance on predicate-oriented relation extraction. The experimental results show that our approach achieves the F-measure of 97.76%, 99.19%, 95.00% and 93.50% on four different types of predicate-oriented relation (action-location, location-action, action-person and person-action) in crime-related news documents using a data set of 1,736 entity pairs. The effects of NE extraction techniques, feature sets and class unbalance on the performance of relation extraction are explored.

Objective. To determine the clinical effects of Thai herbal compress. Methods. International and Thai databases were searched from inception through September 2014. Comparative clinical studies investigating herbal compress for any indications were included. Outcomes of interest included level of pain, difficulties in performing activities, and time from delivery to milk secretion. Mean changes of the outcomes from baseline were compared between herbal compress and comparators by calculating mean difference. Results. A total of 13 studies which involved 778 patients were selected from 369 articles identified. The overall effects of Thai herbal compress on reducing osteoarthritis (OA) and muscle pain were not different from those of nonsteroidal anti-inflammatory drugs, knee exercise, and hot compress. However, the reduction of OA pain in the herbal compress group tended to be higher than that of any comparators (weighted mean difference 0.419; 95% CI −0.004, 0.842) with moderate heterogeneity (I 2 = 58.3%, P = 0.048). When compared with usual care, herbal compress provided significantly less time from delivery to milk secretion in postpartum mothers (mean difference −394.425 minutes; 95% CI −620.084, −168.766). Conclusion. Thai herbal compress may be considered as an alternative for osteoarthritis and muscle pain and could also be used as a treatment of choice to induce lactation. PMID:25861373

"Tian Op", a traditional Thai scented candle, is used for the smoking and flavoring of sweets, cakes, and other desserts for the purpose of adding a unique aroma to the final product. Gas chromatography-olfactometry, aroma extract dilution analysis, and GC-MS were applied to identify the potent odorants in two types of traditional Thai desserts ("num dok mai" and "gleep lum duan") prepared using a Tian Op smoking process. On the basis of the results of AEDA and calculated odor-activity values, the predominant odorants in the Tian Op flavored desserts were vinyl ketones (C(5)-C(9)), n-aldehydes (C(5)-C(11)), (E)-2-unsaturated aldehydes (C(8)-C(11)), and omega-1-unsaturated aldehydes (C(8) and C(9)). Sensory studies of model mixtures confirmed the importance of n-aldehydes, omega-1-unsaturated aldehydes, and guaiacol as predominant odorants; however, the results showed that vinyl ketones and (E)-2-unsaturated aldehydes, despite having high odor-activity values, may be of only minor importance in the typical aroma profiles of traditional Tian Op smoked desserts.

(Re)placing health and health care: mapping the competing discourses and practices of 'traditional' and 'modern' Thai medicine.

PubMed

Del Casino, Vincent J

2004-03-01

In the wake of the AIDS crisis, 'traditional' Thai medicine has received new attention as a means by which people living with HIV and AIDS (PLWHA) can receive some level of care. The revitalization of Thai medicine, however, is complicated by the competing organizational politics and social dynamics that regulate discourses and practices of health and health care in Thailand. This paper examines how Thai medicine is being (re)placed in the context of competing health-care systems and practices. Specifically, this analysis focuses on the complex interrelationships between 'traditional,' holistic medicine and 'modern,' allopathic medicine in a Thai context; and investigates the role of 'Thai medicine' (phaet phaen thai) and 'village medicine' (phaet pheun baan) as part of governmental and non-governmental efforts to provide health care to PLWHA in Chiang Mai, Thailand. The provision of such health care, however, takes place within the context of a struggle over 'local knowledge' and 'global change' and the ways in which places are organized in relation to the available treatment regimens for HIV/AIDS care. What this paper suggests is that the meanings of health and health care are inextricably linked to the complex, contested nature of social relations as they flow in, and are reworked through, particular places.

Mechanical loadings by active exercise or passive low amplitude vibration have been demonstrated to enhance bone mass or delay bone loss. Traditional Thai massage can be anabolic to bone due to the application of physical loading on the body in a rhythmic fashion. To explore the skeletal effect of Thai traditional massage by examining the changes in biochemical markers of bone turnover immediately after the massage. Subjects consisted of 30 healthy females aged 20-40 years. Each subject received Thai traditional massage for 2 hours by a single masseuse. Bone mineral density (BMD) at baseline was measured by dual-energy X-ray absorptiometry (DEXA). C-terminal telopeptide of type 1 collagen (CTx-I) and total procollagen type 1 amino-terminal propeptide (P1NP) were determined by electrochemiluminescence immunoassay. There was a 4.8% increase in serum P1NP concentrations after massage (median 43.4 ng/ml vs. 41.3 ng/ml, p < 0.05). Serum CTx-I also decreased after massage (median 2-hour vs. baseline 0.29 ng/ml vs. 0.31 ng/ml, p < 0.05). There was a nearly significant negative correlation between the percentage change in serum P1NP and BMD at the total femur (r = -0.37, p = 0.056) whereas the statistically significant correlation disappeared between percentage change in bone turnover and the other sites of BMD. Thai traditional massage induces acute changes in bone formation and resorption markers. Study on the more prolonged effects of Thai traditional massage is warranted to explore its implication in the enhancement of bone health.

Among the stress instruments that measure the degree to which life events are perceived as stressful, the Perceived Stress Scale (PSS) is widely used. The goal of this study was to examine the psychometric properties of a Thai version of the PSS-10 (T-PSS-10) with a clinical and non-clinical sample. Internal consistency, test-retest reliability, concurrent validity, and the factorial structure of the scale were tested. A total sample of 479 adult participants was recruited for the study: 368 medical students and 111 patients from two hospitals in Northern Thailand. The T-PSS-10 was used along with the Thai version of State Trait Anxiety Inventory (STAI), the Thai Version of the Rosenberg Self-Esteem Scale (RSES), and the Thai Depression Inventory (TDI). Exploratory Factor Analysis (EFA) yielded 2 factors with eigenvalues of 5.05 and 1.60, accounting for 66 percent of variance. Factor 1 consisted of 6 items representing "stress"; whereas Factor 2 consisted of 4 items representing "control". The item loadings ranged from 0.547 to 0.881. Investigation of the fit indices associated with Maximum Likelihood (ML) estimation revealed that the two-factor solution was adequate [chi2 = 35.035 (df = 26, N = 368, p < 0.111)]; Goodness-of-Fit Index (GFI) = 0.981; Root Mean Square Residual (RMR) = 0.022; Standardized Root Mean square Residual (SRMR) = 0.037, Comparative Fit Index (CFI) = 0.989; Normed Fit Index (NFI) = 0.96, Non-Normed Fit Index (NNFI) = 0.981, Root Mean Square Error of Approximation (RMSEA) = 0.031. It was found that the T-PSS-10 had a significant positive correlation with the STAI (r = 0.60, p < 0.0001), and the TDI (r = 0.55, p < 0.0001); and was significantly negatively correlated with the RSES (r = -0.46, p < 0.0001, N = 368). The overall Cronbach's alpha was 0.85. The ICC was 0.82 (95% CI, 0.72 and 0.88) at 4 week-retest reliability. The Thai version of the PSS-10 demonstrated excellent goodness-of-fit for the two factor solution model, as well as good

2014-02-01

This study explored the health needs, familial and social problems of Thai migrants in a local community in Brisbane, Australia. Five focus groups with Thai migrants were conducted. The qualitative data were examined using thematic content analysis that is specifically designed for focus group analysis. Four themes were identified: (1) positive experiences in Australia, (2) physical health problems, (3) mental health problems, and (4) familial and social health problems. This study revealed key health needs related to chronic disease and mental health, major barriers to health service use, such as language skills, and facilitating factors, such as the Thai Temple. We concluded that because the health needs, familial and social problems of Thai migrants were complex and culture bound, the development of health and community services for Thai migrants needs to take account of the ways in which Thai culture both negatively impacts health and offer positive solutions to problems.

Graphic symbols are a vital part of most augmentative and alternative communication systems. Communication fluency of graphic symbol user depends on how well the relationship between symbols and its referents are learnt. The first aim of this study is to survey the perception of the selected graphic symbols across seven age groups of participants with different educational background. Sixty-five individuals identified themselves as Thai and ranged in age from 10 to 50 years participated in the investigation used 64 graphic symbols. The last aim of this study is to demonstrate the analysis of multimeaning graphic symbols, which will be used in Thai Picture-based communication system. The twenty graphic symbols with 9-14 meanings are analyzed in both syntactic and semantic aspects. The meanings are divided into five categories: noun, verb/adjective, size, color and shape. Respect to the first aim, the results suggest that the participants under investigation with different sexes, age groups, as well as various educational levels perceive the features or inherent characteristics of such graphic symbols similarly. The results of the analysis of multimeaning of graphic symbols indicate that the foundation of Minspeak, polysemy and redundancy of the words illustrates the inherit meanings of the real-life objects, and it also conveys that the Thai graphic symbols are influenced by numerous factors in Thai circumstance such as ability, motivation, experience, worldview and culture.

Objectives To explore individual determinants of workplace injury among Thai workers. Design Cross-sectional analysis of a large national cohort. Setting Thailand. Participants Thai Cohort Study participants who responded to the 2009 follow-up survey were included if they reported doing paid work or being self-employed (n=51 751). Outcome measures Self-reported injury incidence over the past 12 months was calculated. Multivariate logistic regression models were used to test associations between individual determinants and self-reported workplace injury. Results Workplace injuries were reported by 1317 study participants (2.5%); the incidence was 34 (95% CI 32 to 36)/1000 worker-years for men, and 18 (17–20) for women. Among men working ≥41 h and earning <10 000 Baht, the injury rate was four times higher compared with men working <11 h and earning ≥20 001 Baht; differences in injury rates were less pronounced in women. Multivariate modelling showed that working ≥49 h/week (23%) and working for ≤10 000 Bath/month (37%) were associated with workplace injury. The increase in injury risk with increased working hours did not exceed the risk expected from increased exposure. Conclusions Reductions in occupational injury rates could be achieved by limiting working hours to 48/week. Particularly for Thai low wage earners and those with longer workdays, there is a need for effective injury preventive programmes. PMID:23869104

The reliability of the Rosenberg Self-Esteem Scale compared with the Self-Esteem Visual Analog Scale was ther tested between February and March 2008 on 270 volunteers, including 135 patients with psychiatric illness and 135 normal volunteers. The authors analyzed the internal consistency and factor structure of the Rosenberg Self-Esteem Scale-Thai version and the correlation between it and the Visual Analog Scale. The Cronbach's Alpha for the Rosenberg Self-Esteem scale-Thai version was 0.849 and the Pearson's correlation between it and the Self-Esteem Visual Analog Scale 0.618 (p = 0.01). Two factors, viz, the positively and negatively framea items, from the Rosenberg Self-Esteem Scale-Thai version accounted for 44.04% and 12.10% of the variance, respectively. The Rosenberg Self-Esteem Scale-Thai version has acceptable reliability. The Self-Esteem Visual Analog Scale provides an effective measure of self-esteem.

Unexpected Outcomes of Thai Cassava Trade: A Case of Global Complexity and Local Unsustainability

Tracing the Thai cassava (Manihot esculenta) trade network, between 1960 and 2000, offers a compelling example of global complexity at work. The emergence of Thailand’s dominance of world export markets caught the world by surprise. The opening up of a European market for cassava was supposed to be met by Brazilian and Indonesian producers. Instead, Thailand took over the market by 1975. Several factors facilitated this emergence including: entrepreneurial diasporic networks of Thai-Chinese traders, local political economy conditions in both Europe and Thailand, and ecological conditions in Thailand. These same factors also shaped the subsequent timing of the closing of the European market, the emergence of a new industry association, the creation of new cassava products, and the expansion to other markets. Furthermore, the dynamic nature of cassava market yielded equivocal outcomes for both Europe and Thai farmers. PMID:25328444

Body mass index (BMI) cut-off values (>25 and >30) that predict diabetes risk have been well validated in Caucasian populations but less so in Asian populations. We aimed to determine the BMI threshold associated with increased type 2 diabetes (T2DM) risk and to calculate the proportion of T2DM cases attributable to overweight and obesity in the Thai population. Participants were those from the Thai Cohort Study who were diabetes-free in 2005 and were followed-up in 2009 and 2013 (n = 39,021). We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the BMI-T2DM association. We modelled non-linear associations using restricted cubic splines. We estimated population attributable fractions (PAF) and the number of T2DM incident cases attributed to overweight and obesity. We also calculated the impact of reducing the prevalence of overweight and obesity on T2DM incidence in the Thai population. Non-linear modelling indicated that the points of inflection where the BMI-T2DM association became statistically significant compared to a reference of 20.00 kg/m 2 were 21.60 (OR = 1.27, 95% CI 1.00-1.61) and 20.03 (OR = 1.02, 95% CI 1.02-1.03) for men and women, respectively. Approximately two-thirds of T2DM cases in Thai adults could be attributed to overweight and obesity. Annually, if prevalent obesity was 5% lower, ~13,000 cases of T2DM might be prevented in the Thai population. A BMI cut-point of 22 kg/m 2 , one point lower than the current 23 kg/m 2 , would be justified for defining T2DM risk in Thai adults. Lowering obesity prevalence would greatly reduce T2DM incidence.

Frailty is a clinical state of increased vulnerability from aging-associated decline. We aimed to determine if a Thai Frailty Index predicted all-cause mortality in community-dwelling older Thais when accounting for age, gender and socioeconomic status. Data of 8195 subjects aged 60 years and over from the Fourth Thai National Health Examination Survey were used to create the Thai Frailty Index by calculating the ratio of accumulated deficits using a cut-off point of 0.25 to define frailty. The associations were explored using Cox proportional hazard models. The mean age of participants was 69.2 years (SD 6.8). The prevalence of frailty was 22.1%. The Thai Frailty Index significantly predicted mortality (hazard ratio = 2.34, 95% CI 2.10-2.61, p < 0.001). The association between frailty and mortality was stronger in males (hazard ratio = 2.71, 95% CI 2.33-3.16). Higher wealth status had a protective effect among non-frail older adults but not among frail ones. In community-dwelling older Thai adults, the Thai Frailty Index demonstrated a high prevalence of frailty and predicted mortality. Frail older Thai adults did not earn the protective effect of reducing mortality with higher socioeconomic status. Maintaining health rather than accumulating wealth may be better for a longer healthier life for older people in middle income countries. Copyright © 2018. Published by Elsevier B.V.

2018-01-01

Pedagogical Content Knowledge (PCK) was accepted by worldwide Educators that it is a ubiquitous word in the preparation of teachers in the past decade. This study uses Pedagogical Content Knowledge (PCK) framework as a lens for classifying the guidelines and expectations for categorizing expertise teachers. Therefore, the paper tries to clarify the relationship between competencies of Thai expertise teacher and PCK elements. To promote skillful Thai teachers by offering them academic titles, the Office of the Teacher Civil Service and Education Personal Commission were developed to provide guidelines and expectations for categorizing expertise teachers (OTEPC, 2009). This article focuses on the guideline criteria which are three areas of consideration. The first area of consideration is teacher's disciplines including virtues and professional conducts. The second area of consideration is teacher's knowledge and teaching ability. The last area of consider is teacher's performance. It seemed that the OTEPC guideline pay too much attention on the first area. However, there are some issues of PCK appearing on the OTEPC teacher competency. The paper will discuss some suggestions of fill up PCK in the OTEPC guideline. The paper may have implication for Thailand teacher education.

Possible Impacts of Nanoparticles on Children of Thai Construction Industry

Musikaphan, W.; Kitisriworaphan, T.

A possible impact of nanoparticles on human health becomes a concerned issue especially among children who probably lack of self protection. For Thai construction workers, their pre-school children are more likely to expose such the fine particles due to they have to spend their lives in construction site. This study points out the health problems related to nanoparticles exposition among pre-school children of Thai construction workers. The finding indicated that children who reside and play in construction site are more likely to expose to chemical particles and left behind toxic materials during pre and post construction process than others. Thus, urgent policy is strongly recommended for this vulnerable group since all children are very important as the main source of the national productivity in the future, especially in the aging society.

‘For me… it’s a miracle’: injecting beauty among kathoeis in a provincial Thai city

2014-01-01

Background The Thai term kathoei refers to non-gender-normative females, males and intersexual individuals at different stages of the transitional spectrum with recognized social and cultural roles in society. Nevertheless, kathoeis are only tolerated in Thai society. Many kathoeis seek social acceptance through beauty and turn to the off-label injection of various ‘beauty drugs’. Methods The first author conducted an ethnographic study of injection parties at a wedding studio in a Central Thai provincial city between April and September 2011. Data were gathered through participant observation, focus group discussions and narrative interviews with six participants. All data were collected and analyzed in Thai, and later translated. Findings While injection parties provide opportunities for kathoeis to socialize, bond, and share experiential knowledge on chemically-assisted transformation, they also reproduce ideologies of gender, beauty and sexuality that reinforce the notion that if a kathoei is to maintain her beauty, she must use medicines more frequently and in higher doses. Conclusion Injection parties among Thai kathoeis feature drug use that is entirely reasonable in terms of their own lay knowledge. Empowering kathoeis, by providing accessible information on chemicals and health in a way that reflects the complexity and diversity of their practices, would be one way to reduce health risks. Society must give more long-term options to kathoeis to build their sense of self, based on things besides being beautiful. PMID:25047007

Data regarding sexual maturation in Thai boys are limited to only one 1999 study done in Bangkok which found that the ages of onset of Tanner 2 testicular enlargement and pubic hair were 10.8 and 12.4 years, respectively. To determine the age of onset of pubertal maturation and the physical growth of Thai boys at Hat Yai municipality, southern Thailand, in the year 2012. A cross-sectional study was conducted in 1320 healthy boys, aged 6-19 years, during June 2011 to March 2012. Testicular volume and pubic hair development were assessed according to the Tanner staging method. Probit analysis was used to calculate the median age of different stages of testicular enlargement and pubic hair development. The median ages of boys having Tanner 2 testicular enlargement and Tanner 2 pubic hair were 10.6 [95% confidence interval (CI), 10.4-10.7] and 12.0 (95% CI, 11.8-12.2) years, respectively. The youngest ages of boys who had Tanner 2 testicular enlargement and Tanner 2 pubic hair were 8.2 and 9.7 years, respectively. The final height was attained at age 18 years at 170.3 cm, 3.3 cm greater than the 167.0 cm final height of Hat Yai boys studied in 1994. The age of onset of puberty in Hat Yai schoolboys in 2012 was 0.2 years earlier than that of Bangkok schoolboys in 1999. The final adult height of Thai boys increased 3 cm during the two decades.

The purpose of this study was to investigate the psychometric properties of the modified Thai Spiritual Well-Being Scale in patients with advanced cancer. This cross-sectional study was employed to investigate psychometric properties. Some 196 participants from three tertiary hospitals in Bangkok and suburban Thailand were asked to complete a Personal Information Questionnaire (PIQ), The Memorial Symptom Assessment Scale (MSAS), and the Spiritual Well-Being Scale (SWBS). Validity was determined by known-group, concurrent, and constructs validity. Reliability was estimated using internal consistency by Cronbach's α coefficients. Three factors were extracted: so-called existential well-being, religious well-being, and peacefulness accounted for 71.44% of total variance. The Cronbach's α coefficients for total SWB, EWB, RWB, and peacefulness were 0.96, 0.94, and 0.93, respectively. These findings indicate that the Thai SWBS is a valid and reliable instrument, and it presented one more factor than the original version.

The HLA-B∗15:02 allele has been reported to have a strong association with carbamazepine-induced Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) in Thai patients. The HLA-B alleles associated with carbamazepine-induced maculopapular exanthema (MPE) and the drug reaction with eosinophilia and systemic symptoms (DRESS) among the Thai population have never been reported. The aim of the present study was to carry out an analysis of the involvement of HLA-B alleles in carbamazepine-induced cutaneous adverse drug reactions (cADRs) in the Thai population. A case-control study was performed by genotyping the HLA-B alleles of Thai carbamazepine-induced hypersensitivity reaction patients (17 MPE, 16 SJS/TEN, and 5 DRESS) and 271 carbamazepine-tolerant controls. We also recruited 470 healthy Thai candidate subjects who had not taken carbamazepine. HLA-B∗15:02 showed a significant association with carbamazepine-induced MPE (P = 0.0022, odds ratio (OR) (95% confidence interval [CI]) = 7.27 (2.04–25.97)) and carbamazepine-induced SJS/TEN (P = 4.46 × 10−13; OR (95% CI) = 70.91(19.67–255.65)) when compared with carbamazepine-tolerant controls. Carbamazepine-induced SJS/TEN also showed an association with HLA-B∗15:21 allele (P = 0.013; OR (95% CI) = 9.54 (1.61–56.57)) when compared with carbamazepine-tolerant controls. HLA-B∗58:01 allele was significantly related to carbamazepine-induced MPE (P = 0.007; OR (95% CI) = 4.73 (1.53–14.66)) and DRESS (P = 0.0315; OR (95% CI) = 7.55 (1.20–47.58)) when compared with carbamazepine-tolerant controls. These alleles may serve as markers to predict carbamazepine-induced cADRs in the Thai population. PMID:29546073

This study examined the relationship between dietary intake, body weight, and body mass index (BMI) in adult Thais as a function of smoking status. A cross-sectional, nationally representative survey using health and dietary questionnaires and anthropometric measurements were used. Participants were 7858 Thai adults aged 18 years and older recruited from 17 provinces in Thailand. Results demonstrated that smoking is associated with lower weights and BMI. However, when smokers were stratified by smoking intensity, there was no dose-response relationship between smoking and body weight. There is no conclusive explanation for weight differences across smoking groups in this sample, and the results of the present study did not clearly support any of the purported mechanisms for the differences in body weight or BMI. In addition, because the substantial negative health consequences of smoking are far stronger than those associated with modest weight differences, smoking cannot be viewed as an appropriate weight management strategy. © 2011 APJPH.

ETHONOPHARMACOLOGICAL RELEVANCES: Traditional medicines have long been used by the Thai people. Several medicinal recipes prepared from a mixture of plants are often used by traditional medicinal practitioners for the treatment of many diseases including cancer. The recipes collected from the Thai medicinal text books were recorded in MANOSROI II database. Anticancer recipes were searched and selected by a computer program using the recipe indication keywords including Ma-reng and San which means cancer in Thai, from the database for anticancer activity investigation. To investigate anti-cancer activities of the Thai medicinal plant recipes selected from the "MANOSROI II" database. Anti-proliferative and apoptotic activities of extracts from 121 recipes selected from 56,137 recipes in the Thai medicinal plant recipe "MANOSROI II" database were investigated in two cancer cell lines including human mouth epidermal carcinoma (KB) and human colon adenocarcinoma (HT-29) cell lines using sulforhodamine B (SRB) assay and acridine orange (AO) and ethidium bromide (EB) staining technique, respectively. In the SRB assay, recipes NE028 and, S003 gave the highest anti-proliferation activity on KB and HT29 with the IC(50) values of 2.48±0.24 and 6.92±0.49μg/ml, respectively. In the AO/EB staining assay, recipes S016 and NE028 exhibited the highest apoptotic induction in KB and HT-29 cell lines, respectively. This study has demonstrated that the three Thai medicinal plant recipes selected from "MANOSROI II" database (NE028, S003 and S016) gave active anti-cancer activities according to the NCI classification which can be further developed for anti-cancer treatment.

Streptococcus mutans, known to be a pathogen of dental caries as well as bacteremia and infective endocarditis, is classified into four serotypes, c, e, f and k, based on the structures of serotype-specific polysaccharides. Serotype k was recently designated using blood isolates from Japanese subjects and such strains are considered to be virulent in the bloodstream. The purpose of the present study was to analyse the serotype distribution of strains isolated from Thai subjects and determine whether serotype k strains were present. A total of 250 S. mutans strains were isolated from 50 Thai subjects, and serotypes of all strains were determined. Then, molecular and biological analyses were carried out for serotype k strains. Immunodiffusion and polymerase chain reaction analyses showed that serotype c was the most prevalent (70%), followed by serotypes e (22.8%), f (4.4%) and k (2.8%), which indicated that serotype k S. mutans strains occurred in Thai individuals at a similar rate to that previously reported for Japanese and Finnish populations. Molecular analyses of the seven serotype k strains showed extremely low expression of rgpE, which is related to glucose side-chain formation in serotype-specific rhamnose-glucose polymers, similar to previous reports for those other populations. In addition, analysis of the biological properties of the seven serotype k strains demonstrated low levels of sucrose-dependent adhesion, cellular hydrophobicity, dextran-binding activity and phagocytosis susceptibility by human polymorphonuclear leukocytes, which are characteristics similar to those of serotype k strains previously isolated in Japan. Our results indicate the possibility of a worldwide prevalence of serotype k strains with properties in common with those of previously reported strains.

'The family is only one part …': understanding the role of family in young Thai women's sexual decision making.

2014-01-01

This study aims to understand young Thai women's perspectives about family influences on their sexual decisions with the goal of informing the future development of HIV programmes and interventions for young Thai women in urban areas. Eight focus groups were conducted with 40 young single women aged 18-25 years, recruited through a peer network of key informants from four sites across Bangkok: universities, government offices, slums and garment factories. Predetermined topics relating to family, sexual decisions and HIV were discussed with 4-5 participants in each group. Qualitative thematic and framework-analysis techniques were used to explore participants' narratives. Findings suggest that young Thai women's sexual decisions are complex and take place under a wide range of personal, familial and social influences. Parents were perceived as a barrier to parent-child communication about sex and HIV. Young women regarded mothers as more supportive and receptive than fathers when discussing sensitive topics. Young Thai women described a tension between having a strong sense of self and modern sexual norms versus traditionally conservative relational orientations. Future HIV interventions could benefit by developing strategies to consider barriers to parent-child communication, strengthening family relationships and addressing the coexistence of conflicting sexual norms in the Thai context.

Statement of the Thai Grassroots Women's Forum on the occasion of the Fourth World Conference on Women in Beijing, China.

PubMed

1995-06-01

In order to insure the participation of Thai women in the Fourth World Conference on Women, the Thai Grassroots Women's Forum was established in 1994. In seeking ways to improve women's status, the Women's Forum holds as its central position the statement that "Women must have the rights and opportunities to participate in all levels of decision-making processes." The policy implications of this statement affect many aspects of women's lives. In terms of health care, women must be given appropriate information about reproductive health, control over their own bodies must be guaranteed, and the Thai government must develop an occupational health service. All violence against women must be eradicated as a human rights violation, and victimized women must receive help and protection. Women laborers must be included in the labor policy-making process, and the Thai government must ratify International Labor Organization Conventions on workers' organizations, night-time work, rights to collective bargaining, and occupational health and safety. Governments should enact measures to protect women labor migrants, including those who work in the sex industry. The Thai government must support women's groups and provide opportunities for women to participate in government committees at every level. The composition of the Tambol (sub-district) Council should be equally divided between men and women. Finally, the Thai government must terminate any development plan which threatens the environment and must give communities the right to manage their natural resources and environment.

The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1215 participants, 487 (40.1%) were lowland Thai and 728 (59.9%) were from ethnic minorities. Overall, 17.9% of respondents reported "ever had sex." Lowland Thai adolescents were more likely to have ever had sex compared with ethnic minority adolescents (AOR, 1.61; CI, 1.06-2.45; P< 0.01). A higher proportion of lowland Thai respondents reported having ≥ 2 lifetime sexual partners (51.9% vs. 33.3%, P = 0.003), or currently having a boy/girlfriend (59.9% vs. 45.3%, P< 0.001) compared to ethnic minority adolescents. Consistent condom use was low in both groups (22.6%). The common significant factors associated with "ever had sex" in both groups were "ever drunk alcohol in the past year" and "currently having a boy/girlfriend." Specifically, for lowland Thai youth, being around the age of 17 or 18 years and "ever used methamphetamine in the past year" were associated with increased odds of "ever had sex". For ethnic minority adolescents, being female and belonging to religions other than Buddhism were associated with decreased odds of "ever had sex". A substantially higher proportion of lowland Thai engage in risky sexual behaviors when compared to ethnic minorities. However, both groups remained vulnerable to HIV and other sexually transmitted infections. To minimize sexual risks, education program and school-based interventions are warranted to increase awareness of young people about risky behaviors and to promote essential life skills.

Thai Massage, and Thai Herbal Compress versus Oral Ibuprofen in Symptomatic Treatment of Osteoarthritis of the Knee: A Randomized Controlled Trial

PubMed Central

2014-01-01

The aim of this study was to verify the clinical responses to Thai massage (TM) and Thai herbal compression (THC) for treating osteoarthritis (OA) of the knee in comparison to oral ibuprofen. This study was a randomized, evaluator-blind, controlled trial. Sixty patients with OA of the knee were randomly assigned to receive either a one-hour session of TM or THC (three times weekly) or oral ibuprofen (three times daily). The duration of treatment was three weeks. The clinical assessments included visual analog scale assessing pain and stiffness, Lequesne's functional index, time for climbing up ten steps, and physician's and patient's overall opinions on improvement. In a within-group comparison, each treatment modality caused a significant improvement of all variables determined for outcome assessments. In an among group comparison, all modalities provided nearly comparable clinical efficacy after a three-week symptomatic treatment of OA of the knee, in which a trend toward greatest improvement was likely to be found in THC group. In conclusion, TM and THC generally provided comparable clinical efficacy to oral ibuprofen after three weeks of treatment and could be considered as complementary and alternative treatments for OA of the knee.

Body mass index (BMI) cut-offs associated with increased risk of diabetes and cardiovascular disease differ between European and Asian populations, and among Asian populations. Within-population and ethnic variability in body shape has likewise been linked with variability in cardiovascular risk in western settings. To explore differences between Thai and White UK adults in body shape and its associations with height, age and BMI. Data on weight and body shape by 3-D photonic scanning from National Sizing Surveys of UK (3542 men, 4130 women) and Thai (5889 men, 6499 women) adults aged 16-90 years, using a common protocol and methodology, were analysed. Thai adults in both sexes had significantly smaller body girths than UK adults after adjusting for age and height. Matching for BMI, and adjusting for height and age, Thais in both sexes tended to have similar or greater limb girths, but significantly smaller torso girths (especially waist and hip) than UK individuals. These results were replicated within narrow BMI bands at ∼20 and ∼25 kg m(-2). Shape-age associations also differed between the populations. Young Thai adults have a significantly slighter physique than White UK adults, with a less central distribution of body weight. However these differences reduce with age, especially in males. The 3-D photonic scanning provides detailed digital anthropometric data capable of monitoring between- and within-individual shape variability. The technology merits further application to investigate whether variability in body shape is more sensitive to metabolic risk than BMI within and between-populations.

The basic medium formulation was composed of 10 g/L glucose, 3 g/L yeast extract, 0.1 g/L K2HPO4, 0.01 g/L NaCl, 0.01 g/L MgSO4 and 0.01 g/L CaCl2 with initial pH 5.5. The cultures were cultivated on 200 rpm shaking bath at 50 °C for 120 hr. It was found that P. rhodozyma TISTR 5370 grew optimally when cultivated in a mixture of coconut water and Thai rice vermicelli sewage (ratio of 1:3), with growth of 3.23 g dry biomass/L and specific astaxanthin production of 680 μg/g dry cell respectively. When fan palm sugar was added to increase reducing sugar from 10 to 15, 20 and 25 g/L, it was demonstrated that the 15 g/L formulation produced highest both dry cell weight (9.66 g/L) and astaxanthin (810 μg/g dry cell weight). Furthermore, when 0.5, 1.0 and 1.5 g/L citric acid was added as supplement, it was found that 1.0-g/L citric acid formulation gave the best result: 10.30 g/L dried cell weight and 930 μg/g dry cell weight astaxanthin. This study provides a promising alternative method of sewage reduction and valorization of wastewater from Thai traditional rice vermicelli plant.

To study the performance according to the assigned roles of infection control nurses (ICNs) in Royal Thai Army hospitals. Interviewing ICNs in 6 hospitals. During April and May 2002, 11 ICNs in 6 hospitals were interviewed. Two hospitals had been accredited and 4 were applying for hospital accreditation. Full-time ICNs were identified in 5 and part-time in 6. The ICNs were graduated with bachelor and master degrees in 5 and 6 respectively. Two ICNs graduated with master degree in IC. All could perform their roles in administration, education, surveillance, personnel health, consultation and quality improvement. Only 7 ICNs had experience in outbreak investigation. None were principle investigators in research except for their master degrees. The main problem was the absence of ICNs posts in all except 1 hospital. Infection control nurses in Royal Thai Army hospitals in the present study could perform their roles according to assignment except involvement in outbreak investigation in some and in research as the principle investigators in all.

The purpose of a cross-sectional study was to investigate factors influencing the quality of life among Thai workers in textile dyeing factories. Samples included 205 Thai workers from five textile dyeing factories located in the suburban area of Bangkok in Thailand. Data were collected with a self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from 0.70–0.91. The results revealed that the overall quality of life among workers was most likely between good and moderate levels, and the percentage-mean score was 74.77. The seven factors associated with the overall quality of life were co-worker relationships, safety at work in the dimension of accident prevention, job characteristics, supervisory relationships, welfares, marital status, and physical environment. Furthermore, co-worker relationships, accident prevention, and marital status were three considerable predictors accounted for 23% of the variance in the overall quality of life among workers in textile dyeing factories.

Healthy ageing is a concept that concerns older persons' quality of life and is a key factor in promoting well-being. The older population in Thailand is growing. Isan (a region of north-eastern Thailand) has been reported as having one of the most rapidly increasing older populations in the country. In order to care for and promote the health of older people, healthcare providers should understand how healthy ageing is perceived by this target group. Although healthy ageing has been studied in different contexts as well as perspectives, no studies have previously focused on older persons' experiences of healthy ageing from a lifeworld perspective in Isan-Thai. Therefore, the aim of this study is to describe older persons' qualitatively different conceptions of healthy ageing in Isan-Thai culture. A phenomenographic approach with an epistemological base in lifeworld theory was used to disclose the various ways to conceptualize healthy ageing. Individual, qualitative interviews were conducted with 17 people aged 60 and above who live in Isan-Thai. The findings of this study revealed three categories of descriptions: "being independent in dependence," "being at peace," and "being a valuable person." This study also found family members, friends, healthcare providers, and religion important to healthy ageing in the Isan-Thai culture. Understanding how older people conceptualize healthy ageing is valuable for healthcare providers. They can apply these findings regarding healthy ageing in their fieldwork when caring for older people.

Highly added sugar diets have been associated with various health problems such as dental caries, dyslipidemia, obesity and poor quality of life. Unfortunately, sugar consumption, especially sucrose, has increased continuously worldwide. The purpose of the study was to examine sources of sugar consumption and amount of added sucrose consumed in Thai undergraduate students. This study was carried out at Khon Kaen University, Thailand, between the years 2004-2005. A complete 3-day record of items and amounts of sweet consumption were obtained from 202 individuals--38 male and 164 female students. Added sucrose content of each sweetened food and drinks referred to in the record was determined by an enzymatic method. Mean intakes of sucrose were calculated from the sucrose content. The average of sucrose consumption in all subjects was 69+/-38 g/day, ranged from 4 to 182 g/day or 17 teaspoons of added sucrose per day. This amount accounted for 13.8% of total daily energy intake. There was a record of 337 kinds of sweetened foods and drinks found. The major source of added sucrose consumption was sweetened beverage, which was consumed 118 g/day averagely, or 60% of daily sugar consumption. Intake of sucrose per day in both male and female was not statistically difference, neither among different BMI groups. Intake of added sugar in the students was higher than the recommendation of the World Health Organization. These data would be helpful in a health promotion campaign aimed at a reduction of sugar consumption in Thai undergraduate students.

Thai traditional medicine (TTM) is widely practiced in Thailand and continues to gain importance in cancer management, but little is known about the TTM practitioners' emic concepts and practice. With this study we firstly aim to document the practice of cancer treatment and prevention by TTM practitioners and, secondly, to evaluate how such traditional concepts and practices are correlated with biomedical ones. This in turn can form the basis for developing novel strategies for designing pharmacological experiments and longer term strategies to develop TTM practice. Semi-structured interviews with 33 TTM practitioners were performed in five provinces in different regions of Thailand. The following information were recorded; basic information of informants, descriptions of cancer (mareng in Thai), causes, diagnosis, treatment, and prevention. Plants used in the treatment and prevention of mareng were also collected. Using an in depth ethnographic approach four representative case studies to assist in a better understanding of the characteristics of mareng, its diagnosis, treatment, and prevention are reported here. Five characteristics of mareng - waste accumulation (khong sia), chronic illnesses (krasai), inflammation (kan aksep), bad blood (luead) and lymph (namlueang), and the imbalance of four basic elements (dhātu si) - have been identified. Explanatory models of cancer in TTM were linked with biomedical concepts and relevant pharmacological actions. Traditional uses and available scientific evidence of medicinal plants mentioned in the case studies for the treatment or prevention of mareng are presented and discussed. Here for the first time five main characteristics of cancer based on Thai traditional medical concepts are analysed. Our findings are relevant not only for the planning of clinical studies or pharmacological experiment in the search for novel compounds for cancer treatment and prevention, but also for the integration of Thai traditional

To investigate the relationship between Facebook addiction and mental health among high school students. This cross-sectional analytic study was performed among 972 high school students from four provinces associated with high economic prosperity in Thailand: Bangkok, ChiangMai, Ubon Ratchathani and Songkhla, utilizing a multistage cluster sampling technique. Facebook addiction was assessed using the Thai version of the Bergen-Facebook Addiction Scale (Thai-BFAS), while a Thai version ofthe General Health Questionnaire (Thai GHQ-28) was used for mental health evaluation. The relationship between Facebook addiction and mental health was analyzed through multiple logistic regressions. The prevalence of Facebook addiction and abnormal mental health were 41.9% (95% CI; 38.6, 45.2), and 21.9% (95% CI; 19.2, 24.8), respectively. After adjustment for confounding factors (sufficiency of household income, school location, level of education, GPAX learning deficits and attention deficit hyperactivity disorder), the individuals identified as having Facebook addiction were discovered to be at a high risk of developing abnormal general mental health (ORadj = 1.7, 95% CI: 1.1, 2.4), somatic symptoms (OR = 1.2, 95% CI: 0.9, 1.7), anxiety and insomnia (ORadj = 1.3, 95% CI: 0.9, 1.8), social dysfunction (OR = 1.5, 95% CI: 1.1, 2.1) and severe depression (ORadj = 1.5, 95% CI: 1.0, 2.2). Moreover; there were pronounced trends of increasing risk according to the level of Facebook addiction (Ptrend < 0.05). It was found that Facebook addiction among high school students could be associated with abnormal, general mental health status, somatic symptoms, anxiety & insomnia, social dysfunction, and severe depression. Therefore, it is essential that the relevant authorities educate young people about the mental health impacts linked with Facebook addictive usage and impose appropriate public health policies by screening Facebook addiction and mental health issues in risk groups.

Clinical measurement. Currently there are no self-report questionnaires in Thai to evaluate disability levels in patients suffering from upper extremity musculoskeletal disorders. To translate and cross-cultural adaptation the disabilities of the arm, shoulder and hand (DASH) questionnaire to Thai version and to evaluate content validity, construct validity and internal consistency of the questionnaire. The DASH-TH was produced by following cross-cultural adaptation guidelines stated by the Institute for Work and Health (IWH). Forty Thai patients with arm, shoulder or hand problems participated in field testing of the questionnaire. Content validity was determined by obtaining the item-objective congruence (IOC) value for each questionnaire item. Correlation between the DASH-TH score and numeric rating scale was used to assess construct validity. Internal consistency of DASH-TH was measured using Cronbach's alpha coefficient. Forty patients (14 males, 26 females) with arm, shoulder or hand problems enrolled in the present study. The average age of patients was 44.8 years. The index of item-objective congruence (IOC) of each item ranged from 0.7 to 1.0. The Cronbach's alpha coefficient of the questionnaire was 0.938. There was no correlation between DASH-TH score and numeric rating scale. The DASH-TH has high content validity and internal consistency. N/A. Copyright © 2014 Hanley & Belfus.

We investigated influenza interspecies transmission in two commercial swine farms in Thailand. Sera from swine-exposed workers (n=78), age-matched non-swine-exposed healthy people (n=60) and swine populations in both farms (n=85) were studied. Hemagglutination-inhibition (HI) assay was performed on Thai swine H1 viruses (swH1N1 and swH1N2) isolated from both farms. Thai human H1N1 (huH1N1) and pandemic H1N1 2009 (pH1N1) were also used as test antigens. The hemagglutinin (HA) 1 genes of swH1N1 and swH1N2 viruses were sequenced and shown to be genetically distinct from the Thai huH1N1 and pH1N1 viruses. Evidence of pig-to-human influenza virus transmission was found in farm workers with increased odds of elevated antibody titers to both swH1N1 (OR 42.63, 95% CI, 14.65-124) and swH1N2 (OR 58, 95% CI, 13.12-256.3) viruses. No evidence of human-to-pig influenza virus transmission was detected in this study. Copyright © 2010 Elsevier B.V. All rights reserved.

Within the context of Rosenbaum's theory of learned resourcefulness, this correlational study examined the relationships among family functioning, self-esteem, and resourceful coping in Thai adolescents with asthma. A convenience sample of 132 Thai adolescents (aged 12-17 years) with asthma was recruited from the outpatient asthma clinics of four hospitals in Bangkok. Self-administered questionnaires included an assessment of demographic information and asthma status, the revised Family APGAR, the Rosenberg Self-Esteem Scale, and the Children's Self-Control Scale. Hierarchical multiple regression analysis was used to examine the relationships among variables. Effective family functioning had a significant positive effect on self-esteem (beta = .27, p < .01) and resourceful coping (beta = .30, p < .01), controlling for gender and age. However, self-esteem was not significantly correlated with resourceful coping (beta = .15, p = .08). The findings suggest that nursing interventions should take into account the role of family functioning in promoting self-esteem and resourceful coping in Thai adolescents with asthma. Recommendations for future research include replication of the study with a larger sample of adolescents with asthma and with adolescents with other chronic illnesses.

To develop a conceptual framework of adherence to treatment among Thai people living with tuberculosis, a grounded theory approach was used. A purposive sample of 20 Thai people living with tuberculosis, aged from 23 to 85 years, was interviewed. From the participants' perspective, a core category of social belonging was highlighted, with three categories of conditions connected: personal barriers, personal resilience, and social facilitation. Personal barriers encompassed fear of stigma, concealing the illness, and lack of knowledge and motivation to complete the treatment regime. Personal resilience encompassed positive thinking and self-awareness. Social facilitation encompassed the ease of access to health services, continuity in the health service's ability to choose a directly-observed therapy observer, and social support. This study contributes a deeper understanding of the perspective of Thai people living with tuberculosis with regards to adherence to tuberculosis treatment. It might improve how local healthcare workers provide tuberculosis care, and inspire them to tailor care to people living with tuberculosis in a local community to increase personal resilience and reduce stigma. © 2017 John Wiley & Sons Australia, Ltd.

Cross-sectional observational study to investigate psychometric properties of an adapted Thai version of the refined Scoliosis Research Society-22 (SRS-22) questionnaire. To evaluate the reliability and validity of the adapted Thai version of the refined SRS-22 questionnaire. The SRS-22 questionnaire is a valid instrument for assessing the health-related quality of life for patients with adolescent idiopathic scoliosis. Recently, the questionnaire has been translated and validated in many languages for non-English-speaking countries. Translation/retranslation of the English version of the SRS-22 was conducted, and the cross-cultural adaptation process was performed. The Thai version SRS-22 and previously validated Thai version Short-Form survey version 2.0 (SF-36V2) questionnaires were administered to 77 patients with adolescent idiopathic scoliosis who had surgical treatment. Fifty-eight patients (52 adolescent girls) had filled out the first set of questionnaires. Thirty patients of the first-time responders completed the second set of questionnaires. The mean age at the time of operation was 14.6 years and the mean age at the time of the final follow-up was 18.7 years. The mean preoperative scoliosis curve magnitude was 55.4° (range, 30°-95°) and postoperative curve magnitude was 20.1° (range, 0°-60°). Internal consistency was determined with Cronbach α coefficient. Intraclass correlation coefficient was used for test-retest reliability. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36V2 questionnaire, using the Pearson correlation coefficient. The mean overall Cronbach α coefficient of the adapted Thai version SRS-22 was 0.76. The 2 of corresponding domains (mental health = 0.80 and self-image = 0.83) had satisfactory internal consistency and the remaining domains (pain = 0.78; function/activity = 0.74; and satisfaction = 0.76) were good. The intraclass correlation coefficient for 5 domains was ranged from

An internship program between Vietnamese student teachers from Cantho University and Thai graduate students from Srinakharinwirot University has occurred in June 2016. There were six Vietnamese student teachers and four Thai graduate students participated in this program with the help of science teachers from two schools in Sa Kaeo and Chachoengsao Provinces of Thailand. To explore Vietnamese and Thai students' life experiences and their perceptions in science and Mathematics teaching, reflective journals were used to record their progress as team teaching in primary and lower secondary classrooms in the form of the online format via social media in English language. The data were collected from 54 reflective journals from their eight days experiences at the schools. The data were analyzed qualitatively using Van Manen's level of reflectivity which composed of three levels; 1) Technical Rationality (TR), 2) Practical Action (PA) and 3) Critical Reflection (CR). The results explicitly revealed that the three levels of reflectivity have appeared in the reflective journals. Besides, Vietnamese and Thai students have learned more from each other and can exchange their educational experiences and culture. Certainly, this was the first time for them to teach science and mathematics in English to Thai students. Moreover, they have shared their impressions toward schools, teachers and also students in the schools in their reflective journal as well.

To study the extent of Internet addiction (IA) and its association with depression in Thai medical students. A cross-sectional study was conducted at Faculty of Medicine, Ramathibodi Hospital. Participants were first- to fifth-year medical students who agreed to participate in this study. Demographic characteristics and stress-related factors were derived from self-rated questionnaires. Depression was assessed using the Thai version of Patient Health Questionnaire (PHQ-9). A total score of five or greater derived from the Thai version of Young Diagnostic Questionnaire for Internet Addiction was classified as "possible IA". Then chi-square test and logistic regression were used to evaluate the associations between possible IA, depression and associated factors. From 705 participants, 24.4% had possible IA and 28.8% had depression. There was statistically significant association between possible IA and depression (odds ratio (OR) 1.92, 95% confidence interval (CI): 1.34-2.77, P-value <0.001). Logistic regression analysis illustrated that the odds of depression in possible IA group was 1.58 times of the group of normal Internet use (95% CI: 1.04-2.38, P-value = 0.031). Academic problems were found to be a significant predictor of both possible IA and depression. IA was likely to be a common psychiatric problem among Thai medical students. The research has also shown that possible IA was associated with depression and academic problems. We suggest that surveillance of IA should be considered in medical schools.

Although, the effect of Ramadan fasting on the risks for Cardiovascular Disease (CVD) has been reported in several studies, the results were inconsistent. In addition, the effect of Ramadan fasting on biochemical parameters in Thai subjects has not been evaluated. The aim of this study was to investigate the effect of Ramadan fasting on anthropometry, blood pressure, Fasting Blood Glucose (FBG), lipid profiles, and body composition in healthy Thai subjects. A total of 65 healthy subjects (21 men and 44 women) aged between 19-24 years were randomly recruited. Anthropometry, blood pressure, FBG, Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein-Cholesterol (HDL-C), Low Density Lipoprotein-Cholesterol (LDL-C), and body composition were measured before Ramadan, end of Ramadan and after one month of Ramadan. There were no changes in anthropometry, blood pressure, lipid profiles and body composition in both genders before Ramadan, end of Ramadan and after one month of Ramadan. Nevertheless, FBG levels were significantly increased after one month of Ramadan compared with baseline (5.09±0.50 versus 4.83±0.38 mmol/L, p=0.016, respectively) in women. The Ramadan fasting did not affect the lipid, anthropometric and body composition in healthy Thai subjects. However, the increased FBG levels after one month of Ramadan were observed in women. To improve the favourable biochemical parameters after Ramadan fasting, the lifestyle modifications such as, increased intake of healthy diets and increased physical activity should be recommended.

Boxing is often believed to be a frequent cause for parkinsonism caused by chronic repetitive head injury, with Muhammad Ali frequently cited as an example. The purpose of this study is to determine the prevalence of Parkinson's disease (PD) in retired Thai traditional boxers. Two standardized screening questionnaires were sent to all registered Thai traditional boxers. Subjects who screened positive for parkinsonism were invited for clinical examinations by two independent neurologists. Among 704 boxers (70%) who completed the questionnaires, 8 boxers (1.14%) had parkinsonism: 5 with PD, 1 with progressive supranuclear palsy and 2 with vascular parkinsonism. Boxers with PD were found to have an older mean age than those without PD (P = 0.003). The analysis of probable risk factors disclosed an association between the number of professional bouts (>100 times) and PD (P = 0.01). The crude prevalence of PD in Thai boxers was 0.71% (95% CI: 0.09-1.33), with a significant increase with age. The prevalence rate of PD in those aged 50 and above was 0.17% (95% CI: 0.15-0.20), age-adjusted to the USA 1970 census, which is comparable to that of the general populations. The analysis determined that the number of professional bouts is a risk factor among these boxers, supporting the notion that repetitive head trauma may pose an additional risk to certain individuals who are already susceptible to PD. © 2010 Movement Disorder Society.

Renin-angiotensin-aldosterone system (RAS) blockers are commonly used for cardiovascular diseases. Currently, little information exists for the Asian population on angioedema, a rare yet serious adverse event. This study aimed to describe characteristics of RAS blockers-associated angioedema (RASBA) in Thai patients. A retrospective study using the national pharmacovigilance database of Thailand was undertaken. Cases indicating the presence of angioedema with RAS blockers uses from 1984-2011 were identified. Patient demographics, co-morbidities, concomitant drugs, information for the RAS blockers and angioedema were obtained as well as causality assessment and quality of reports. A total of 895 cases were identified. Mean age was 59.9+12.8 years and 66.5% being female. Most angioedema events (48.6%) occurred during the first week of treatment. Angiotensin converting enzyme inhibitors (87.7%) were the most commonly implicated agents followed by angiotensin receptor blockers (10.5%), aldosterone antagonist (2.1%) and direct renin inhibitor (0.2%). Out of the 895 cases incorporated in this study, 165 (18.4%) were classified as serious events and resulted in hospitalization. The overall case fatality rate was 0.4%. Respiratory disturbance occurred in 46 cases (5.1%). Patients with respiratory complications tended to be younger (53.4+13.9 vs 60.3+12.7 years old; p=0.002) and with higher frequency of allergy history (26.1% vs 14.7%; p=0.032) compared to those without respiratory complications. Based on multivariate logistic regression, the adjusted OR for history of allergy was 2.23 (95%CI: 1.04 - 4.78, p = 0.041). RASBA in Thai population occurred mostly in elderly female patients and often led to hospitalization. Since large number of patients is regularly exposed to RAS-blockers, a nationwide attempt to raise awareness of clinicians when prescribing RAS-blockers is prudent.

The prevalence of unexpected antibodies in the Northeastern-Thai population was studied. Sera were collected from 25,673 blood donors including 18,209 males and 7,464 females. The sera were screened for unexpected antibodies by saline and enzyme techniques. The sera which gave a positive antibody screening test were identified for specificity of antibody. The result demonstrated that 3,928 from 25,673 samples (15.30%) were positive for the antibody screening test and only 3,883 samples could be identified for specificity of antibody. The most common unexpected antibodies were anti-P1, anti-lewis and anti-P1 + anti-lewis with the frequency of 70.8, 18.6 and 10.1 per cent, respectively. The prevalence of anti-P1 in this study was higher than that reported in Central Thailand and Southeast Asia which may due to the high prevalence of liver fluke infection in the Northeastern-Thai population.

Examine intakes of energy and macronutrients, and identify their food sources, in Thai preschool children. Data from the Thai National Health Examination Survey (NHES) IV were used. Mothers/caregivers were interviewed regarding their children's 24-hour-dietary intake. Dietary data were analyzed for energy and macronutrients, and their food sources were investigated. Due to skewed data, Mann-Whitney U test was used to compare energy and macronutrient intake between sexes and age groups. Among 256 preschool children, more than 90% had protein intakes higher than the recommended level. Only 12.7 to 29.0% met the recommended intake for energy. Amounts of carbohydrate and fat consumed varied from below to above the Dietary Reference Intake (DRI) recommendation. Intakes of carbohydrate in boys and fat in girls were statistically different between age groups (p < 0.05). Fifty to 60% of energy came from dairy products, grains and starchy products. The major carbohydrate contributors were grains and starchy products. Dairy products were the main source of protein. Important food sources of fat were dairy products for one- to three-year-old children and fat and oils for four- to five-year-old children. Thai preschool children have inappropriate intakes of energy and macronutrients. Dairy products and grains and/or starchy products were the main sources of energy, carbohydrate, and protein. Dietary fat sources varied by age group.

This study explored the extent to which Malaysian and Thai smokers believe "light" and menthol cigarettes are less harmful than "regular" cigarettes and the correlates of these beliefs. The study used data from wave 1 of the International Tobacco Control Southeast Asia Survey. 2006 adult smokers (95.3% male) from Malaysia and 2000 adult smokers (94.5% male) from Thailand were interviewed face to face in 2005. 29% of Malaysian respondents reported currently smoking light cigarettes and 14% menthols, with 19% agreeing that lights are less harmful and 16% agreeing that menthols are less harmful. 38% of Thai respondents reported currently smoking light cigarettes and 19% menthols, with 46% agreeing that lights are less harmful and 35% agreeing that menthols are less harmful. Malaysian smokers reporting current use of light or menthol cigarettes were more likely to believe that they are less harmful. Reported use of lights did not relate to beliefs for Thai respondents. The belief that light and/or menthol cigarettes are less harmful was strongly related to the belief that they have smoother smoke. The experience of smoother smoke is likely to produce some level of belief in reduced harm, regardless of how brands are labelled and whether or not Federal Trade Commission FTC/International Organisation for Standardisation tar, nicotine and carbon monoxide yield figures are used.

This paper is a report of a study of how Thai Buddhist people with type 2 diabetes practice self-management. The importance of diabetes self-management is recognized in the literature. However, research on self-care management in Thailand, in particular concerning Buddhist people with type 2 diabetes, is scarce. A descriptive qualitative study was conducted. Purposive convenience sampling was used, and thirty men and women with diabetes, aged 28-79 years, participated. Data were collected from June to August 2009 and analysed by use of manifest and latent content analysis. Five themes of self-management among Thai Buddhist people with type 2 diabetes were identified: cultural influence on disease control, Buddhism and Thai culture, struggle for disease control, family support and economy a high priority. Even though the Buddhist people with diabetes had certain self-management capabilities, many had poor control of their blood sugar levels and needed assistance. Reference to Buddhist moderation can be an effective means of helping the people with diabetes better manage their disease and change their lifestyles. In addition to cultural and religious traditions, family, economy and social environment should be taken into account both in the care and in interventions aimed at helping people with diabetes cope and empowering them to control their disease. © 2011 Blackwell Publishing Ltd.

To investigate emergent literacy skills, including phonological awareness when presented with an initial phoneme-matching task and letter knowledge when presented with a letter-naming task in Thai preschoolers, and to identify key factors associated with those skills. Four hundred twelve typically developing children in their final kindergarten year were enrolled in this study. Their emergent reading skills were measured by initial phoneme-matching and letter-naming tasks. Determinant variables, such as parents' education and teachers' perception, were collected by self-report questionnaires. The mean score of the initial phoneme-matching task was 4.5 (45% of a total of 10 scores). The mean score of the letter-naming task without a picture representing the target letter name was 30.2 (68.6% of a total of 44 scores), which increased to 38.8 (88.2% of a total of 44 scores) in the letter-naming task when a picture representing the target letter name was provided. Both initial phoneme-matching and letter-naming abilities were associated with the mother's education and household income. Letter-naming ability was also influenced by home reading activities and gender. This was a preliminary study into emergent literacy skills of Thai preschoolers. The findings supported the importance of focusing on phonological awareness and phonics, especially in the socioeconomic disadvantaged group.

Thai silk fibroin and gelatin are attractive biomaterials for tissue engineering and controlled release applications due to their biocompatibility, biodegradability, and bioactive properties. The development of electrospun fiber mats from silk fibroin and gelatin were reported previously. However, burst drug release from such fiber mats remained the problem. In this study, the formation of beads on the fibers aiming to be used for the sustained release of drug was of our interest. The beaded fiber mats were fabricated using electrospinning technique by controlling the solution concentration, weight blending ratio of Thai silk fibroin/gelatin blend, and applied voltage. It was found that the optimal conditions including the solution concentration and the weight blending ratio of Thai silk fibroin/gelatin at 8-10% (w/v) and 70/30, respectively, with the applied voltage at 18 kV provided the fibers with homogeneous formation of beads. Then, the beaded fiber mats obtained were crosslinked by the reaction of carbodiimide hydrochloride (EDC)/N-hydroxysuccinimide (NHS). Methylene blue as a model active compound was loaded on the fiber mats. The release test of methylene blue from the beaded fiber mats was carried out in comparison to that of the smooth fiber mats without beads. It was found that the beaded fiber mats could prolong the release of methylene blue, comparing to the smooth fiber mats without beads. This was possibly due to the beaded fiber mats that would absorb and retain higher amount of methylene blue than the fiber mats without beads. Thai silk fibroin/gelatin beaded fiber mats were established as an effective carrier for the controlled release applications. Copyright © 2013 Elsevier B.V. All rights reserved.

To report the magnitude of the problem and to evaluate the outcome of maternal illicit drug use in Thai parturients. Retrospective case-control study. Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University. The subjects were 44,640 parturients who had deliveries at Siriraj Hospital from January 1998 to December 2001 and were divided into two groups. The study group consisted of 66 parturients with a history of illicit drug use and the control group consisted of 44,574 parturients without a history of illicit drug use. Medical records of 66 parturients with a history of illicit drug use were reviewed. Obstetric statistics of the department were retrieved from the computerized database in the Division of Obstetric and Gynecologic Registry. The data were analyzed using descriptive statistics. Characteristics of parturients, pregnancy outcome, type and incidence of illicit drug. Within the study period, 66 cases of maternal illicit drug use were identifiable during the intrapartum period; 65 cases used amphetamine or derivatives and 1 case used an opioid derivative. The number had risen from 1 case in 1998 to 58 cases in 2001. Mean age of the patients was 23.30 +/- 6.04 years. Compared to the control group which included 44,574 parturients, the patients had a lower incidence of antenatal care (ANC rate = 21.21% vs 94.35%; RR = 0.23, 95% CI = 0.14-0.26), a higher incidence of HIV infection (10% vs 2%; RR = 6.09, 95% CI = 2.83-13.12), a higher incidence of birth before arrival (BBA rate = 9.09% vs 1.06%; RR = 8.59, 95% CI = 3.98-18.51), and a lower cesarean section rate (10.60% vs 26.36%; RR = 0.40, 95% CI = 0.20-0.81). There were no serious intrapartum, immediate postpartum and neonatal complication. Fetal outcome included a higher incidence of low birth weight infants (22.73% vs 10.23%; RR = 2.22, 95% CI = 1.42-3.46) and a smaller head circumference than the normal range of Thai fetal biometry (31.85 +/- 1.47 cm).

The CFD code CFX4.4 was used to simulate an experiment in the ThAI facility, which was designed for investigation of thermal-hydraulic processes during a severe accident inside a Light Water Reactor containment. In the considered experiment, air was initially present in the vessel, and helium and steam were injected during different phases of the experiment at various mass flow rates and at different locations. The main purpose of the simulation was to reproduce the non-homogeneous temperature and species concentration distributions in the ThAI experimental facility. A three-dimensional model of the ThAI vessel for the CFX4.4 code was developed. The flowmore » in the simulation domain was modeled as single-phase. Steam condensation on vessel walls was modeled as a sink of mass and energy using a correlation that was originally developed for an integral approach. A simple model of bulk phase change was also introduced. The calculated time-dependent variables together with temperature and concentration distributions at the end of experiment phases are compared to experimental results. (authors)« less

In case of species of natural and aromatic plant originated from the northern Thailand, sensory characteristics, especially odours, have unique identifiers of herbs. The instruments sensory analysis have performed by several of differential of sensing, so call `electronic nose', to be a significantly and rapidly for chemometrics. The signal responses of the low cost electronic nose were evaluated by principal component analysis (PCA). The aims of this paper evaluated various of Thai-herbs grown in Northern of Thailand as data preprocessing tools of the Low-cost electronic nose (enNU-PYO1). The essential oil groups of Thai herbs such as Garlic, Lemongrass, Shallot (potato onion), Onion, Zanthoxylum limonella (Dennst.) Alston (Thai name is Makaen), and Kaffir lime leaf were compared volatilized from selected fresh herbs. Principal component analysis of the original sensor responses did clearly distinguish either all samples. In all cases more than 97% for cross-validated group were classified correctly. The results demonstrated that it was possible to develop in a model to construct a low-cost electronic nose to provide measurement of odoriferous herbs.

Universities in Thailand are preparing for Thailand's integration into the ASEAN Economic Community (AEC) by increasing the number of tests in English language. English language is not the native language of Thailand Differences in English language proficiency may affect scores among test-takers, even when subject knowledge among test-takers is comparable and may falsely represent the knowledge level of the test-taker. To study the impact of English language multiple choice test questions on test scores of medical students. The final examination of fourth-year medical students completing internal medicine rotation contains 120 multiple choice questions (MCQ). The languages used on the test are Thai and English at a ratio of 3:1. Individual scores of tests taken in both languages were collected and the effect of English language on MCQ was analyzed Individual MCQ scores were then compared with individual student English language proficiency and student grade point average (GPA). Two hundred ninety five fourth-year medical students were enrolled. The mean percentage of MCQ scores in Thai and English were significantly different (65.0 ± 8.4 and 56.5 ± 12.4, respectively, p < 0.001). The correlation between MCQ scores in Thai and English was fair (Spearman's correlation coefficient = 0.41, p < 0.001). Of 295 students, only 73 (24.7%) students scored higher when being tested in English than in Thai language. Students were classified into six grade categories (A, B+, B, C+, C, and D+), which cumulatively measured total internal medicine rotation performance score plus final examination score. MCQ scores from Thai language examination were more closely correlated with total course grades than were the scores from English language examination (Spearman's correlation coefficient = 0.73 (p < 0.001) and 0.53 (p < 0.001), respectively). The gap difference between MCQ scores in both languages was higher in borderline students than in the excellent student group (11.2 ± 11

Youth substance abuse is widely recognized as a major public health issue in Thailand. This study explores family and community risk and protective factors relevant to alcohol and illegal drug misuse in 1,778 Thai teenagers. Strong family attachment and a family history of antisocial behaviors were strongly associated with nearly all forms of substance abuse, with adjusted odds ratios ranging from 5.05 to 8.45. Community disorganization was strongly associated with self-reported substance use, although involvement in prosocial activities acted as a protective factor. The findings suggest that interventions that promote family cohesion and encourage community involvement may have considerable benefits in reducing substance abuse in Thai adolescents.

Due to increasing globalization and Internet communication, the number of international marriages has increased. In Sweden, 75% of the Thai population are women, among whom 80% are partnered with Swedish or other Scandinavian men. Previous studies have indicated that lack of autonomy, social isolation, and stigma are important risk factors for poor mental health for foreign-born women as well as for women in international marriages. To explore what characterizes the processes, choices, challenges and relational conditions that Thai women, partnered with Swedish or Danish men, experience during their first years in Sweden. A qualitative study using a Constructivist Grounded Theory approach based on fourteen individual interviews with Thai women partnered with Swedish or Danish men and residing in Sweden. The core category 'possibilities to maintain a strong self in Sweden' is linked to five categories characterizing the process that the women go through over time. The subcategories illustrate different paths taken even if there were possibilities to change paths along the way. The women had, for different reasons, reached a turning point that made them leave Thailand. In Sweden, they started in dependency and struggled in different ways to adjust to relational norms and handle prejudice. Toward the end of the timeline, differing ways of recognizing life choices depended on access to social networks and partners' attitudes. Our study showed the crucial role of economical, emotional and social support from partners and networks for Thai women's possibilities to maintain a strong self and good health after migration. This implies a need for supporting Thai women to be more independent by providing access to language education, employment and community involvement. The current requirement for becoming a permanent resident should also be reviewed not to jeopardize women international marriages possibilities' to leave unhealthy relationships.

This study investigated the presence of antinuclear antibody (ANA) in older Thais compared with middle-age and younger participants. Antinuclear antibody represents the first step in the diagnostic testing for lupus erythematosus (LE) and other autoimmune diseases. Due to the lack of reference ANA levels in older, middle-age and younger Thais healthy participants, this study will be useful for determining the proper diagnostic and treatment criteria. There were 28 older (60-76 years), 17 middle-age (41-59 years) and 13 younger (24-40 years) participants in this study. Immunofluorescence was performed to analyse the ANA staining pattern and titre levels in the participants' blood samples. The presence of serum ANA was found in 18 of 28 cases (64.3%), four of 17 (23.5%) and one of 13 cases (7.7%) of the older, middle-age and younger participants, respectively. The difference in the number of serum ANA-positive participants between the older, middle-age and younger groups was statistically significant (p < 0.05). Interestingly, the ANA positive in older participants presented more than one staining pattern. The speckled pattern was the most commonly detected ANA staining pattern in the older group, being found in 12 cases followed by cytoplasmic pattern (10 cases), homogeneous pattern (nine cases) and nucleolar pattern (five cases). In the middle-age group, the speckled pattern was found in four cases, whereas one younger participant presented a nucleolar pattern. Serum ANA positive was significantly higher in the older group compared with the middle-age and younger groups. There were variations of the serum ANA staining patterns in the older group. © 2016 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

Nineteen young Thai women were purposively selected from networks of nongovernmental organizations involving children and youths in Bangkok. Our grounded theory findings indicated that these young women used the basic social process they called "waiting for the right time" in order to maintain heterosexual abstinence. Waiting for the right time involved one overarching condition, honoring parental love, and included three overlapping properties: learning rules, planning life path, and ways of preserving virginity. The findings provide information that may lead to the development of culturally competent interventions for middle-class Thai youths to remain healthy and avoid pregnancy.

Introduction Although, the effect of Ramadan fasting on the risks for Cardiovascular Disease (CVD) has been reported in several studies, the results were inconsistent. In addition, the effect of Ramadan fasting on biochemical parameters in Thai subjects has not been evaluated. Aim The aim of this study was to investigate the effect of Ramadan fasting on anthropometry, blood pressure, Fasting Blood Glucose (FBG), lipid profiles, and body composition in healthy Thai subjects. Materials and Methods A total of 65 healthy subjects (21 men and 44 women) aged between 19-24 years were randomly recruited. Anthropometry, blood pressure, FBG, Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein-Cholesterol (HDL-C), Low Density Lipoprotein-Cholesterol (LDL-C), and body composition were measured before Ramadan, end of Ramadan and after one month of Ramadan. Results There were no changes in anthropometry, blood pressure, lipid profiles and body composition in both genders before Ramadan, end of Ramadan and after one month of Ramadan. Nevertheless, FBG levels were significantly increased after one month of Ramadan compared with baseline (5.09±0.50 versus 4.83±0.38 mmol/L, p=0.016, respectively) in women. Conclusion The Ramadan fasting did not affect the lipid, anthropometric and body composition in healthy Thai subjects. However, the increased FBG levels after one month of Ramadan were observed in women. To improve the favourable biochemical parameters after Ramadan fasting, the lifestyle modifications such as, increased intake of healthy diets and increased physical activity should be recommended.

Thailand is one of the most common countries of origin among immigrants in Sweden and Thai immigrants comprise the immigrant group most frequently diagnosed with HIV. Little is known about their healthcare-seeking behaviour and views on HIV prevention. This study explored Thai women's healthcare-seeking behaviour in relation to sexual and reproductive health and their views on HIV prevention. Nineteen in-depth interviews were conducted with Thai-born women in the Stockholm area. Three themes were identified: (1) poor access to healthcare in Sweden, preferring to seek care in Thailand; (2) partners playing a key role in women's access to healthcare; (3) no perceived risk of HIV, but a positive attitude towards prevention. Despite expressing sexual and reproductive healthcare needs, most women had not sought this type of care, except for the cervical cancer screening programme to which they had been invited. Identified barriers for poor access to healthcare were lack of knowledge about the healthcare system and language difficulties. To achieve 'healthcare on equal terms', programmes and interventions must meet Thai women's healthcare needs and consider what factors influence their care-seeking behaviour. Integrating HIV prevention and contraceptive counselling into the cervical screening programme might be one way to improve access.

The efficiency and productivity of aquaculture strongly depends on the development of advanced technology for water quality management system. The most important factor for the success of intensive aquaculture system is controlling the water quality of fish rearing media. This paper reports the design of fine bubbles (FBs) generator and performance evaluation of the system to improve water quality in thai catfish media (10 g/ind) with density (16.66 ind./L). The FBs generator was designed to control the size distribution of bubble by controlling its air flow rate entry to the mixing chamber of the generator. The performance of the system was evaluated based on the produced debit, dissolved oxygen rate and ammonia content in the catfish medium. The size distribution was observed by using a high speed camera image followed by processing using ImageJ. freeware application. The results show that air flow rate 0.05 L/min and 0.1 L/min received average bubble size of 29 µm and 31 µm respectively. The generator produced bubbles with capacity of 6 L/min and dissolved oxygen rate 0.2 ppm/min/L. The obtained DO growth was 0.455 ppm/second/L while the average decay rate was 0.20 ppm/second/L. (0.011/0.005 fold). In contrast, the recieved DO growth rate is faster compared to the DO consumption rate of the Thai catfish. This results indicated that the potential application of FBs enhanced the density of thai catfish seed rearing. In addition, ammonia can be reduced at 0.0358 ppm/hour/L and it is also observed that the inhibition of bacterial growth of air FBs is postive to Aeromonas hydrophila bacteria compared to the negative control. It is concluded that as-developed FBs system can be potentially applied for intensive thai catfish culture and expected to improve the feeding efficiency rate.

To find reliability of parental or caregiver's report and testing of the Thai Speech and Language Test for Children Aged 0-4 Years Old. Five investigators assessed speech and language abilities from video both contexts: parental or caregivers' report and test forms of Thai Speech and Language Test for Children Aged 0-4 Years Old. Twenty-five normal and 30 children with delayed development or risk for delayed speech and language skills were assessed at age intervals of 3, 6, 9, 12, 15, 18, 24, 30, 36 and 48 months. Reliability of parental or caregivers' testing and reporting was at a moderate level (0.41-0.60). Inter-rater reliability among investigators was excellent (0.86-1.00). The parental or caregivers' report form of the Thai Speech and Language test for Children aged 0-4 years old was an indicator for success at a moderate level. Trained professionals could use both forms of this test as reliable tools at an excellent level.

The purpose of this paper is to explore effective mechanisms towards environmental awareness enhancement of the Thai public company. The environmental awareness has been strongly mentioned in the international agenda such as Agenda 21 to achieve sustainable development and be implemented at the global communities in all sectors. Thailand’s environmental awareness has been set up as the national policy and continuously promoted in the business sectors. The selected study area is one of Thai industrial public companies mainly utilizing natural resources for its business. Data collection was conducted by using questionnaires with a stratified sampling method comprising of 28 managerial and 134 operational levels. Descriptive statistics were be used for data analysis presented in terms of percentage. The study found that the effective mechanisms towards environmental awareness enhancement include employees’ participation in environmental friendly field trip, environmental knowledge provided by the company, supply chain involvement, law enforcement, and international environmental standard applied by the company. This study would recommend that public participation should be involved in order to make the mechanisms effectively.

Cross-border mobility and social networks: Laotians seeking medical treatment along the Thai border.

Bochaton, Audrey

2015-01-01

Drawing upon research conducted on cross-border patients living in Laos and seeking care in Thailand, this paper examines the important role played by social networks in patients' decision-making and on the itineraries they choose to seek treatment on the Thai side of the border. Due to the vastly contrasting situations between the two countries in terms of healthcare supply, and considering Laotians' increasing demand for high quality healthcare, a number of them have managed to satisfy their needs by combining cross-border treatment with the use of the healthcare facilities provided by their own country. This study consisted first of household surveys conducted in five border areas (2006-2007) in Laos in order to quantify and map out cross-border healthcare-related travel patterns. Afterwards, interviews were conducted with cross-border patients (55), Laotian and Thai medical doctors (6), Thai social workers (5), and officials working in public institutions (12). While socioeconomic and spatial factors partly explain cross-border mobility, patients' social networks significantly influence treatment itineraries throughout the decision-making process, including logistical and financial considerations. The social networks existing at different geographical levels (neighbourhood, regional and global) are therefore a powerful analytical tool not only for understanding the emergence of these cross-border movements but also for justifying them in an authoritarian political environment such as Lao PDR's.

To survey the knowledge and attitudes towards Down syndrome screening in the final year of training of Thai obstetrics and gynaecology residents. A self-administered structured questionnaire of knowledge and attitudes towards Down syndrome screening was developed One hundred thirty six residents were asked to respond to the questionnaire on their last day of the Thai board examination in the year 2006 and 2007. The data was analyzed using SPSS for windows version 15.0. Eighty-two completed questionnaires surveys were returned (60% response rate). The mean total score of knowledge of Down syndrome and its screening test was 81%. Eighty percent of respondents (65/82) had positive attitudes towards counseling for screening Down syndrome for all pregnant women. Fifty-four percent (44/82) had negative attitudes towards Down syndrome screening for all pregnant women. Sixty percent (49/82) favored nuchal translucency measurement by ultrasonography for screening in the first trimester Training institutes, age, sex, and the counseling experience of residents did not affect the attitudes. The final-year Thai Obstetrics and Gynaecology residents had good knowledge and positive attitudes towards Down syndrome screening. More than half of the residents had negative attitudes towards the screening of all pregnant women. Educational programs and training are needed to address these deficiencies before screening programs are widely implemented.

Objective This study explored the extent to which Malaysian and Thai smokers believe “light” and menthol cigarettes are less harmful than “regular” cigarettes and the correlates of these beliefs. Methods The study used data from wave 1 of the International Tobacco Control Southeast Asia Survey. 2006 adult smokers (95.3% male) from Malaysia and 2000 adult smokers (94.5% male) from Thailand were interviewed face to face in 2005. Results 29% of Malaysian respondents reported currently smoking light cigarettes and 14% menthols, with 19% agreeing that lights are less harmful and 16% agreeing that menthols are less harmful. 38% of Thai respondents reported currently smoking light cigarettes and 19% menthols, with 46% agreeing that lights are less harmful and 35% agreeing that menthols are less harmful. Malaysian smokers reporting current use of light or menthol cigarettes were more likely to believe that they are less harmful. Reported use of lights did not relate to beliefs for Thai respondents. The belief that light and/or menthol cigarettes are less harmful was strongly related to the belief that they have smoother smoke. Conclusions The experience of smoother smoke is likely to produce some level of belief in reduced harm, regardless of how brands are labelled and whether or not Federal Trade Commission FTC/International Organisation for Standardisation tar, nicotine and carbon monoxide yield figures are used.

Health-related quality of life (HRQOL) is increasingly being considered in the management of patients with various conditions. HRQOL instruments can be broadly classified as generic or disease-specific measures. Several generic HRQOL instruments in different languages have been developed for paediatric populations including the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0) Generic Core Scale. This tool and a condition-specific tool, PedsQL 3.0 Cerebral Palsy (CP) Module, are widely used in children with CP. No psychometric properties have been reported for Thai PedsQL 4.0. Therefore, this study aimed to explore the psychometric properties of the Thai version of the PedsQL 4.0 Generic Core Scales and compare these with the values for the Thai PedsQL 3.0 CP Module reported previously. Thai PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 CP Module were completed, respectively, by children with CP and their parents or caregivers twice within 2-4 weeks. Respondents were 97 parents or caregivers and 54 children. Minimal missing data were found in most scales. Acceptable internal consistency was supported, except for Emotional, Social, and School Functioning. Intraclass correlation coefficients for parent-proxy report and self-report were good to excellent (0.625-0.849). The feasibility and reliability of the Thai PedsQL 4.0 Generic Core Scales were supported. The Thai PedsQL 3.0 CP Module showed higher values for the psychometric properties. Low-to-good correlations were found among the scales between the PedsQL 4.0 Generic Core Scales and the 3.0 CP Module. Both instruments could be used to measure HRQOL for children with CP, and may provide different information.

The Thai National Telescope (TNT) is a Ritchey-Chretien Telescope with a clear aperture ΦM1 = 2.3 m, a focal ratio f/10 and a central obstruction Obsc = 0.3. The TNT is the main instrument of the Thai National Observatory (TNO) which is located near the summit of the Doi Inthanon, situated in the Chiang Mai Province of Thailand at altitude 2,457 meters. The median seeing on this site is approximately 0.9" and is remarkably stable on most nights, rarely exceeding 2". We decided to develop an optical setup to simulate in laboratory conditions the geometry of the TNT output beam. This, in order to carefully prepare and to improve the efficiency of the test to be performed in real conditions at the TNT focal plane level. We specified the setup to be representative of the TNT optical design, beam aperture, central obscuration, geometry of the spider, wavefront quality and PSF size under various seeing conditions. This setup comprises 2 identical Cassegrain telescopes mounted on dedicated supports with 5 degree-of-Freedom. The first application of this setup will be the preparation of the TNT optical alignment. The second application of this setup will be the development and the test of the future instruments for the TNT such as a focal reducer or a spectrograph. In this paper, we discuss the setup specifications we describe the setup optical and mechanical design and we present the performance.

Purpose This study assessed the accuracy of age estimates produced by a regression equation derived from lower third molar development in a Thai population. Materials and Methods The first part of this study relied on measurements taken from panoramic radiographs of 614 Thai patients aged from 9 to 20. The stage of lower left and right third molar development was observed in each radiograph and a modified Gat score was assigned. Linear regression on this data produced the following equation: Y=9.309+1.673 mG+0.303S (Y=age; mG=modified Gat score; S=sex). In the second part of this study, the predictive accuracy of this equation was evaluated using data from a second set of panoramic radiographs (539 Thai subjects, 9 to 24 years old). Each subject's age was estimated using the above equation and compared against age calculated from a provided date of birth. Estimated and known age data were analyzed using the Pearson correlation coefficient and descriptive statistics. Results Ages estimated from lower left and lower right third molar development stage were significantly correlated with the known ages (r=0.818, 0.808, respectively, P≤0.01). 50% of age estimates in the second part of the study fell within a range of error of ±1 year, while 75% fell within a range of error of ±2 years. The study found that the equation tends to estimate age accurately when individuals are 9 to 20 years of age. Conclusion The equation can be used for age estimation for Thai populations when the individuals are 9 to 20 years of age. PMID:27051633

Chaiwan, Sakkarin

This study was designed to determine situation and effectiveness of the safety management system currently implemented in the Royal Thai Air Force. Reviewing the ICAO's SMS and the RTAF's SMS was conducted to identify similarities and differences between the two safety management systems. Later, the researcher acquired safety statistics from the RTAF Safety Center to investigate effectiveness of its safety system. The researcher also collected data to identify other factors affecting effectiveness of the safety system during conducting in-depth interviews. Findings and Conclusions: The study shows that the Royal Thai Air Force has never applied the International Civil Aviation Organization's Safety management System to its safety system. However, the RTAF's SMS and the ICAO's SMS have been developed based on the same concepts. These concepts are from Richard H. Woods's book, Aviation safety programs: A management handbook. However, the effectiveness of the Royal Thai Air Force's safety system is in good stance. An accident rate has been decreasing regularly but there are no known factors to describe the increasing rate, according to the participants' opinion. The participants have informed that there are many issues to be resolved to improve the RTAF's safety system. Those issues are cooperation among safety center's staffs, attitude toward safety of the RTAF senior commanders, and safety standards.

Substance use and delinquency in Thai adolescents are growing public health concerns. Research has linked neighborhood characteristics to these outcomes, with explanations focused on neighborhood disorganization, social cohesion, and social control. This study examines the independent associations of these neighborhood constructs with Thai adolescents' substance use and delinquency, through peer deviance, to determine which neighborhood aspects are particularly important. Families (N=420) with adolescents aged 13-14 were randomly selected from 7 districts in Bangkok, Thailand. Structural equation modeling showed that adolescents', but not parents', perceptions of greater disorganization were related to increased rates of both minor and serious delinquency. Surprisingly, greater neighborhood cohesion was related to greater minor delinquency. Peer deviance was unrelated to neighborhood variables. Findings can inform prevention strategies for Thai adolescents, as results suggest that neighborhoods are important for adolescent behaviors regardless of culture. Further work should help communities make use of social cohesion to benefit residents.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a major swine pathogen causing economic losses in the swine industry almost worldwide. PRRSV has been divided into 2 genotypes, the European (Type 1) and North American (Type 2) genotype, respectively and displays a large degree of genetic variability, particularly at the nonstructural protein (nsp) 2 gene. This is the first study determining genetic variation of the nsp2 of Thai PRRSV isolates. The results showed that 9 out of 10 Thai PRRSV isolates were nsp2-truncated viruses that might have evolved from a virus previously introduced in the past, but not from one recently introduced.

Four Thai synthetic chicken lines (Kaen Thong, Khai Mook Esarn, Soi Nin, and Soi Pet) originated from Thai native and exotic commercial chickens were evaluated for their growth and carcass traits with the purpose of developing a Thai broiler breeding program. Insulin-like growth factor I (IGF-I) gene is known to play an important role in growth, proliferation and differentiation. Consequently, we investigated the possibility of using the IGF-I gene for marker-assisted selection in Thai synthetic chickens. We looked for variations in the IGF-I gene and studied their association with growth and carcass traits; 1046 chickens were genotyped using PCR-RFLP methods. A general linear model was used to analyze associations of the IGF-I polymorphism with growth and carcass traits. Kaen Thong, Khai Mook Esarn, and Soi Nin chickens were found to carry similar frequencies of alleles A and C (0.40-0.60), while Soi Pet chickens had high frequencies of allele C (0.75). The IGF-I gene was significantly associated with some growth traits (body weight at hatching, and at 4, 8, 12, and 14 weeks of age; average daily gain during 0-12 and 0-14 weeks of age) in all synthetic chickens. Carcass traits (the percentage of dressing and pectoralis major) were significantly different only in Khai Mook Esarn chickens. We conclude that IGF-I can be used as a marker gene for the selection of growth and carcass traits of synthetic chickens in a marker-assisted selection program.

G6PD deficiency is common in malaria endemic regions and is estimated to affect more than 400 million people worldwide. Treatment of malaria patients with the anti-malarial drug primaquine or other 8-aminoquinolines may be associated with potential haemolytic anaemia. The aim of the present study was to investigate the prevalence of G6PD variants in Thai population who resided in malaria endemic areas (western, northern, north-eastern, southern, eastern and central regions) of Thailand, as well as the Burmese population who resided in areas along the Thai-Myanmar border. The ten common G6PD variants were investigated in dried blood spot samples collected from 317 Thai (84 males, 233 females) and 183 Burmese (11 males, 172 females) populations residing in malaria endemic areas of Thailand using PCR-RFLP method. Four and seven G6PD variants were observed in samples collected from Burmese and Thai population, with prevalence of 6.6% (21/317) and 14.2% (26/183), respectively. Almost all (96.2%) of G6PD mutation samples collected from Burmese population carried G6PD Mahidol variant; only one sample (3.8%) carried G6PD Kaiping variant. For the Thai population, G6PD Mahidol (8/21: 38.1%) was the most common variant detected, followed by G6PD Viangchan (4/21: 19.0%), G6PD Chinese 4 (3/21: 14.3%), G6PD Canton (2/21: 9.5%), G6PD Union (2/21: 9.5%), G6PD Kaiping (1/21: 4.8%), and G6PD Gaohe (1/21: 4.8%). No G6PD Chinese 3, Chinese 5 and Coimbra variants were found. With this limited sample size, there appeared to be variation in G6PD mutation variants in samples obtained from Thai population in different regions particularly in the western region. Results indicate difference in the prevalence and distribution of G6PD gene variants among the Thai and Burmese populations in different malaria endemic areas. Dosage regimen of primaquine for treatment of both Plasmodium falciparum and Plasmodium vivax malaria may need to be optimized, based on endemic areas with supporting data on

Polycystic ovarian syndrome (PCOS) is a common and complex condition characterized by endocrine features and influenced by genetic and environmental factors. In Southeast Asia and Thailand, the prevalence of PCOS is unknown. The aim of this study was to estimate the prevalence of and determine factors associated with PCOS in Thai adolescents. We administered a validated questionnaire to 600 university female participants aged 17-19 years from Mahidol University in Bangkok. Of these, 548 (91.33%) responded and agreed to participate. Two-hundred and seventy-nine girls (50.91%) were identified as likely having PCOS and defined as 'probable cases'. Of those 279 participants, 248 (88.88%) were evaluated further for PCOS using the Rotterdam criteria. A complete history was taken, and a physical examination including trans-abdominal ultrasound was performed. Blood chemistry tests were performed to exclude similar conditions and to investigate potential co-morbidities. The prevalence of PCOS in Thai adolescents was found to be 5.29%. After multivariate analyses, moderate acne was the strongest risk factor for PCOS. The odd ratios (95% confidence interval) for the presence of mild acne, moderate acne, and oligo- or amenorrhea in participants with PCOS were 2.83 (1.01-7.90; p = .47), 31.69 (10.07-99.67; p < .001), and 5.89 (2.42-14.37; p < .001), respectively.

This article presents an analysis of news reports containing information or opinions about lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ) people taken from six Thai media outlets over a period of one year. The aim was to explore how LGBTIQ people are portrayed in news media narratives. LGBTIQ identities were found to be vastly underrepresented and, when represented, were often represented inaccurately, stereotypically, harmfully, or without a clear understanding of the diversity of sexual orientations, gender identities, and gender expressions. (Hetero-)sexist narratives, negative portrayals, harmful stereotypes, and discriminatory speech were also widely found, fueling a climate of stigmatization and discrimination of LGBTIQ people in Thai society. This article suggests that key stakeholders in Thai news media should be sensitized on the human rights of LGBTIQ people and on basic professional ethics in journalism.

The productivity of the new crossbred cattle Kabinburi (K) was compared to that of Thai Brahman (TB) using 756 production records from K cattle and 1,316 production records from TB cattle kept at three locations in Thailand. The data were analyzed for the effect of breeds and locations. The ambient temperature, the humidity, the Temperature-Humidity Index (THI) and the rainfall of the three locations were different. Lamphayaklang Livestock Research and Breeding Center (LP) had the highest rainfall/year followed by Nongkwang Livestock Research and Breeding Center (NK), and Prachinburi Livestock Breeding Station (PC). Kabinburi cattle had a higher bodyweight at birth as well as at 200, 400 and 600 days of age than TB cattle. Furthermore, K heifers gave birth to their first calf at a younger age and had a shorter calving interval than TB cows. Thai Brahman cattle kept at LP had significantly higher bodyweight at 400 and 600 days than the animals kept at NK, but bodyweight at birth and 600 days of age were not significantly different. Thai Brahman cattle kept at LP were younger at first calving and had a shorter calving interval than the animals kept at NK. K cattle kept at NK were heavier at birth and at 200, 400 and 600 days of age than the animals kept at PC. Furthermore, Kabinburi cows kept at NK were younger at first calving ( P < 0.01), but the calving interval was not different between the two groups kept at NK or PC.

Substance use and delinquency in Thai adolescents are growing public health concerns. Research has linked neighborhood characteristics to these outcomes, with explanations focused on neighborhood disorganization, social cohesion, and social control. This study examines the independent associations of these neighborhood constructs with Thai adolescents’ substance use and delinquency, through peer deviance, to determine which neighborhood aspects are particularly important. Families (N=420) with adolescents aged 13–14 were randomly selected from 7 districts in Bangkok, Thailand. Structural equation modeling showed that adolescents’, but not parents’, perceptions of greater disorganization were related to increased rates of both minor and serious delinquency. Surprisingly, greater neighborhood cohesion was related to greater minor delinquency. Peer deviance was unrelated to neighborhood variables. Findings can inform prevention strategies for Thai adolescents, as results suggest that neighborhoods are important for adolescent behaviors regardless of culture. Further work should help communities make use of social cohesion to benefit residents. PMID:24465060

This study sought to identify factors associated with intention to change sexual practices among heterosexual Thai males diagnosed with sexually transmitted infections (STIs). STI clinic patients (n = 247) reported their sexual behaviors and condom use during the previous 3 months. STI and HIV knowledge, motivation to change sexual practices, and behavioral skills were assessed. Then, self-reported behavior change intention, including consistent condom use, reducing number of sexual partners, not using drugs and alcohol when having sex, and refusal of condomless sex, was examined. Consistent condom use in the past 3 months by Thai males diagnosed with STIs was low across all types of sexual partners (lover 13.8%, casual partner 14.9%, and sex worker 2.5%). Risk reduction self-efficacy (p < 0.001), perceived benefits from condom use (p < 0.001), perceived barriers to condom use (p < 0.001), perceived risk for HIV (p < 0.05), and STI and HIV knowledge (p < 0.05) were significantly correlated with behavior change intention. Significant predictors of behavior change intention were risk reduction self-efficacy (p < 0.001), perceived benefits of condom use (p = 0.016), and perceived risk for HIV (p = 0.033). They explained 36% of behavior change intention variance. Intervention aimed at enhancing motivation and behavioral skills to adopt preventive behaviors should be developed to prevent recurrent STIs, including HIV infection, among heterosexual Thai males diagnosed with STIs.

This work aims to study the antioxidants capacity, Total phenolic content and antibacterial activity of Thai medicinal plant for the treatment of dermatitis-related inflammations, Capparis micracantha. Crude extract from stem of Thai medicinal plant was extracted with hexane, ethyl acetate, methanol and water. The antioxidant activities (IC50) was evaluated with 1,1-diphenyl-1-princylhydrazyl (DPPH) radical scavenging assay. Total phenolic content (TPC) was determined by using Folin-Ciocalteu method. Bacterial activities was tested with four human pathogenic bacteria; Escherichia coli, Listeria monocytogenes, Staphylococcus aureus and Stapylococcus epidermidis by using agar diffusion assay. Minimum Inhibition Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were also determined by broth dilution method. For antioxidant activity, the methanol fraction from stem extract showed the highest activity with an IC50 of 2.4 mg/ml. Water extraction was the high TPC with 10,136.9 mg GAE/g dry weight. Methanol and water extraction showed the remarkable inhibition of bacterial growth was shown against L. monocytogenes and S. aureus. In addition, ethyl acetate, methanol and water fraction from stem extract against S. epidermidis. The present finding suggests that the extract of C. micracantha could be used to discover bioactive natural products that may serve as pharmaceutical products.

In this research, the natural radioactivity concentrations and their respective annual effective dose of the naturally occurring radionuclides 226Ra, 228Ra and 40K in selected medicinal herb plants were investigated. Seven kinds of popular Thai medicinal herb plants had been studied: turmeric, ginger, safflower, moringa, gotu kola, garlic and alexandria senna. The radiological risk associated with the use of these medicinal plants was assessed. The activity concentrations of 226Ra, 228Ra and 40K were determined using the gamma-ray spectrometry technique. The radioactivity concentrations were found to range from less than 0.20 to 6.67 Bqkg-1 for 226Ra, less than 0.10 to 9.69 Bqkg-1 for 228Ra, and from 159.42 to 1216.25 Bqkg-1 for 40K. Gotu kola showed the highest activity concentrations of 226Ra and 228Ra, while ginger showed the highest activity concentration of 40K. The total annual effective dose due to ingestion of these herb plants were found to range from 0.0028 to 0.0097 mSvy-1 with an average value of 0.0060±0.0001 mSvy-1. The results conclude that the Thai medicinal herb plants samples from this research are considered safe in terms of the radiological hazard.

This report conducts a material selection of different types of steel for UBC Steel Bridge Team. I am a third-year material engineering student, so the result from this material selection can only be taken into consideration but not fully adopted. As part of my academic journey, it is possible for technical mistakes in this material selection process. The mechanic properties are the most effective category of properties, making it necessary to be justified from the steel bridge design and chosen in accordance with the objective of the team. An introduction for currently-used steel properties and the expected steel properties is provided. The examination focus on how different alloy compositions of steel changes its properties. The properties of the steel are examined in three main aspects: hardness, strength, and toughness. The results suggest that more nickel, manganese, and chromium in the steel provide better steel for the team to use. Further research is needed if a more precise material selection is required.

The objective of this study was to evaluate the effects of a 12-week Dao De Xin Xi exercise, modified short forms of Tai Chi, on balance and quality of life in Thai elderly population. Quasi-Experimental research, pretest-posttest one group design was done at Physical Medicine and Rehabilitation Department, Phramongkutklao Hospital. Thai healthy elderly women over the age of 60, requiring regular Dao De Xin Xi exercise were recruited from either patients or workers in the hospital. A 60-minute Dao De Xin Xi exercise class was set as 3 times per week for 12 weeks. At baseline and 12 weeks, participants were tested in their static balance (Single-Leg Stance Timed Test with eyes open and close), dynamic balance (Expanded Timed Up and Go (ETUG) Test). Quality of life was measured by the abbreviated Thai version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire. Fourteen females were studied with mean age of 62.8±4.3 years old. The Single-Leg Stance Timed Test with eyes open and close, Expanded Timed Up and Go (ETUG) Test improved significantly (before versus after exercises p <0.001). Significant improvement in quality of life were also found in each 4 domains, including physical health, psychological, social relationship, and environment (before versus after exercises p =0.001, 0.001, 0.004 and 0.005 respectively). No significant improvement was found only in the right Single-Leg Stance Timed Test with eyes close (p =0.091). A three times per week for 12-week Dao De Xin Xi exercise may help Thai elderly women improve both static, dynamic balance and quality of life. PMID:22980114

Sydney Sexual Health Centre (SSHC) Xpress clinic has significantly reduced the length of stay and waiting time for clients at SSHC but is currently only available to clients who can read and understand a high level of English. This reduces access for culturally and linguistically diverse (CALD) clients. This study sought to determine the acceptability of 4 proposed components of an express clinic model among CALD clients: computer-assisted self-interview (CASI), self-collection of swabs/urine specimens, not having a physical examination, and consultation with a health promotion officer rather than with a clinician. Differences in acceptability based on language group, new or return client status, sex worker status, clinic visited status, and age were analyzed. A cross-sectional, anonymous questionnaire was offered to all female Chinese, Thai, and Korean clients attending SSHC between March and November 2012. Multivariate regression and Pearson χ statistical analyses were conducted using STATA 12 software. A total of 366 questionnaires were returned from 149 Thai, 145 Chinese, and 72 Korean participants. After multivariate analysis, the only predictor of willingness to use an express model of service provision was language group: overall, 67% Thai (odds ratio, 3.74: confidence interval [CI], 2.03-6.89; P < 0.01) and 64% Korean (odds ratio, 3.58; CI, 1.77-7.25, P < 0.01) said that they would use it compared with 35% Chinese. Age, history of sex work, new or returning clients, and general or language clinic attendance did not impact on choices. Within the preference for individual components of the model, more Thai women were happy with using a health promotion officer (43.2%) than Chinese (14.1%) or Korean (8.5%) (P < 0.001); no groups were happy with forfeiting a physical examination; Thai (48.6%) and Korean (40.9%) were happier with self-swabbing than Chinese women (23.9%, P < 0.001); and more Thai were happy to use a CASI (44.2%) than Chinese (12%) or Korean (11

The extent to which family and friends contribute to psychological well-being (PWB) may be subject to cultural variability. This study examines the mechanisms by which relationships with family and friends contribute to PWB among Thai elders. Interviews were conducted with 469 men and women aged 60 and older in Nan Province, Thailand. The data were analyzed using structural equation modeling, controlling for age, gender, education, income, marital status, and health status. Family and friendship networks have a significant direct effect on family and friendship support. However, family and friendship networks do not have a significant direct effect on PWB, but rather an indirect effect via social support. Similarly, friendship support mediates the relationship between friendship networks and family support. Both family support and friendship support are significantly related to PWB but family support is the stronger predictor. Using an adapting theoretical framework developed by Berkman, Glass, Brissette, & Seeman (2000) allows researchers to map the various pathways by which relationships with family and friends may contribute to PWB among older Thai adults.

Changes in the aroma characteristics of Thai 'tom yam' seasoning powder, containing lemongrass, galangal and kaffir lime leaf, as affected by different packaging materials were assessed using quantitative descriptive analysis (QDA) and gas chromatography-mass spectrometry (GC-MS). The descriptive aroma attributes for lemongrass, galangal and kaffir lime leaf powders were developed by the QDA panel. The mixed herb and spice seasoning powder was kept in glass jars closed with different packaging materials (Nylon 6, polyethylene terephthalate (PET) and polylactic acid (PLA)) stored at 38 °C (accelerated storage condition), and evaluated by the trained QDA panel during storage for 49 days. The descriptive words for Thai 'tom yam' seasoning powder developed by the trained panelists were lemongrass, vinegary and leafy for lemongrass, galangal and kaffir lime leaf dried powder, respectively. The aroma intensities significantly (P ≤ 0.05) decreased with increased storage time. However, the intensity scores for aroma attributes were not significantly (P > 0.05) different among the packaging materials studied. The major components in Thai 'tom yam' seasoning powder, quantified by GC-MS, were estragole, bicyclo[3.1.1]heptane, β-bisabolene, benzoic acid and 2-ethylhexyl salicylate. The concentrations of major aroma compounds significantly (P ≤ 0.05) decreased with storage time. Aroma stability of Thai 'tom yam' powder can be determined by descriptive sensory evaluation and GC-MS analysis. Nylon, PET and PLA exhibited similar aroma barrier properties against key aroma compounds in Thai 'tom yam'. This information can be used for prediction of aroma loss through packaging materials during storage of Thai 'tom yam'. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

2016-01-01

Dry Thai traditional tobacco (Nicotiana Tabacum L.) production involves a unique process: (a) picking tobacco leaves, (b) curing tobacco leaves, (c) removing stems of tobacco leaves, cutting leaves and putting on a bamboo rack, (d) drying in the sun, reversing a rack, spraying a tobacco extract to adjust the tobacco's color, storing dried tobacco and packaging. These processes may lead to adverse health effects caused by dermal absorption of nicotine such as Green Tobacco Sickness (GTS). The aim of this study was to determine the correlation between GTS resulting from dry Thai traditional tobacco production and salivary cotinine levels among Thai traditional tobacco farmers in Nan Province, Thailand. A prospective cohort study was conducted with 20 tobacco farmers and 20 non-tobacco farmers in Praputtabath Sub-District and Phatow Sub-District. The participants were randomly selected and interviewed using in person questionnaires with bi-weekly follow-up for 14 weeks. During each contact, the cotinine concentration was measured by NicAlert(TM) Saliva strip tests (NCTS). Descriptive statistics and Spearman's correlation (Spearman's rho) was used to examine the relationship between the variables at both 0.01 and 0.05 significant probability levels. This study indicated that GTS from dry tobacco production has the potential to be considered a common occupational disease. This study demonstrated the usefulness of salivary cotinine level measurements by NCTS. The levels were well correlated with farmers who were employed in the dry Thai tobacco production industry. Salivary cotinine levels were also significantly correlated with the prevalence of GTS in the group of tobacco farmers at any given time within a crop season. However, the production process of dry Thai traditional tobacco is different from that evaluated in our previous studies where GTS and salivary cotinine level were correlated in workers working in humid conditions.

First sexual experience and current sexual behaviour among older Thai men and women.

PubMed

Ford, Kathleen; Chamratrithirong, Aphichat

2009-09-01

The focus of most studies of sexual behaviour has been on younger adults and adolescents, because they are perceived as having higher levels of sexual activity than older persons, and a consequently higher risk of HIV infection. Much less attention has been paid to the sexual behaviour of men and women in their forties and fifties. Using a life course framework, the objective of the present study is to examine AIDS knowledge, HIV testing and sexual risk behaviours among Thai men and women aged 40-59 years. The study also examines the influence of initial sexual experiences on later sexual behaviour. Data for the study are from the 2006 Thai National Survey of Sexual Behaviour, a national probability sample of 6048 individuals. Older Thai men and women were well informed about methods of HIV transmission, but many were unaware of antiretroviral (ARV) medications. Older adults were also less accepting of HIV positive persons than were younger adults. Fewer than half of the older adults had undergone HIV testing, with testing associated with medical checkups or undertaken before operations. Reported condom use was very low with regular partners, moderate with casual partners, and high with sex workers. While the age at first sex has not changed markedly, the type of partner has changed over time. Fewer men have their first sex with a commercial partner. In general, first sex with someone with strong ties to the respondent was related to lower levels of risk behaviour in late adulthood. Areas of concern for AIDS prevention programs include condom use with casual partners and paid partners, knowledge of ARV, and attitudes towards persons living with AIDS.

Background Men are overrepresented with regard to alcohol addiction and in terms of alcohol treatment worldwide. In Thailand, alcohol consumption continues to rise, but few of those afflicted with alcohol addiction attend alcohol treatment programs, even though there is universal care for all. No comprehensive studies have been done on men’s experiences with addiction and alcohol treatment programs in Thailand. Objective The aim of this study was to explore men’s experiences in terms of the ‘pros and cons of alcohol consumption’ in order to identify the barriers that exist for Thai men with regard to alcohol addiction and the decision to stop drinking. Design Purposive sampling was applied in the process of recruiting participants at an alcohol clinic in a hospital in Thailand. Thirteen men with alcohol addiction (aged 32–49 years) were willing to participate and were interviewed in thematic interviews. The analysis of the data was done with descriptive phenomenology. Results Through men’s descriptions, three clusters of experiences were found that were ‘mending the body’, ‘drinking as payoff and doping related to work’, and ‘alcohol becoming a best friend’ as ways of describing the development of addiction. Conclusions The results highlight the importance of addressing concepts of masculinity and related hegemonic ideas in order to decrease the influence of the barriers that exist for Thai men with alcohol addiction with regard to entering treatment and to stop drinking.

The cellular antioxidant enzymes play the important role of protecting the cells and organisms from the oxidative damage. Natural antioxidants contained in fruits have attracted considerable interest because of their presumed safety and potential nutritional value. Even though antioxidant activities of many fruits have been reported, the effects of phytochemicals contained in fruits on the induction of antioxidant enzymes in the cells have not been fully defined. In this study, we showed that extracts from Antidesma ghaesembilla , Averrhoa bilimbi , Malpighia glabra , Mangifera indica, Sandoricum koetjape , Syzygium malaccense, and Ziziphus jujuba inhibited H 2 O 2 -induced intracellular reactive oxygen species production in HEK-293 cells. Additionally, these Thai fruit extracts increased the mRNA and protein expressions of antioxidant enzymes, catalase, glutathione peroxidase-1, and manganese superoxide dismutase. The consumption of Thai fruits rich in phenolic compounds may reduce the risk of oxidative stress.

Lundberg, P C

2000-10-01

The purpose of this study was to discover and describe the meanings and expressions of cultural care of a group of Thai immigrants in Sweden. Participants included 15 key informants and 24 general informants living in and around the town of Uppsala. The conceptual framework was provided by Leininger's theory of cultural care diversity and universality. Use was made of the ethnonursing method and the Sunrise Model in the search for multiple and related dimensions that influenced the generic and professional care practices of the Thai immigrants. Four major themes were formulated. Thus, care (a) means family and kinship relationships as expressed in daily life, (b) is expressed in traditional gender roles, (c) means religious beliefs as expressed in the Buddhist worship, and (d) means support of traditional health care practices. These themes support the cultural care theory and also confirm the Sunrise Model.

Measles remains a major public health concern in Thailand despite the introduction of vaccination since 1984. Similar to other countries, Thailand has experienced numerous measles outbreaks including adult communities such as university student dormitories, prisons, refugee camps, and military recruit camps. These outbreaks raise questions on the seroprotective antibody level in Thai adults. To better understand measles susceptibility in young Thai adults, a retrospective measles seroprevalence study on repository serum specimens obtained with informed consent from young Thai men entering the Royal Thai Army (RTA) during 2007-2008 was conducted. A total of 7760 stratified randomized samples were chosen by residence province. Measles IgG titer was measured using a commercial IgG quantitative ELISA kit following the manufacturer's instructions. An antibody level ≥ 250 International Units per Liter (IU/L) was interpreted as seropositive. The overall measles seroprevalence was 78.5 % (95 % Confidence Interval: 77.6-79.4 %) with geometric mean titer of 738 IU/L (95 % Confidence Interval: 716-760 IU/L). The measles seroprevalence by province ranged from 59.6 % to 93.1 %. A trend of decreasing seroprevalence in the younger cohorts despite increasing immunization coverage was found. Lower seroprevalence than vaccination coverage was observed in the youngest age group. To achieve long term measles control and elimination, an integrated two doses vaccination strategy has been implemented in children in Thailand. This nationwide measles seroprevalence study in young adult RTA recruits found a measles seroprevalence lower than WHO's recommendation for measles outbreak prevention and elimination. These results raise concerns for measles control in Thailand. Supplementary immunization in young adults is essential especially in high-risk and densely populated communities to establish herd immunity for outbreak prevention and elimination.

Purpose This paper prospectively examined two kinds of social normative beliefs about smoking, secular versus religious norms, to determine their relative importance in influencing quitting behaviour among Muslim Malaysian and Buddhist Thai smokers. Methods Data come from 2166 Muslim Malaysian and 2463 Buddhist Thai adult smokers who participated in the first three waves of the International Tobacco Control Southeast Asia project. Respondents were followed up about 18 months later with replenishment. Respondents were asked at baseline about whether their society disapproved of smoking and whether their religion discouraged smoking and those recontacted at follow-up were asked about their quitting activity. Results Majority of both religious groups perceived that their religion discouraged smoking (78% Muslim Malaysians and 86% Buddhist Thais) but considerably more Buddhist Thais than Muslim Malaysians perceived that their society disapproved of smoking (80% versus 25%). Among Muslim Malaysians, religious, but not societal, norms had an independent effect on quit attempts. By contrast, among the Buddhist Thais, while both normative beliefs had an independent positive effect on quit attempts, the effect was greater for societal norms. The two kinds of normative beliefs, however, were unrelated to quit success among those who tried. Conclusions The findings suggest that religious norms about smoking may play a greater role than secular norms in driving behaviour change in an environment like Malaysia where tobacco control has been relatively weak until more recently but in the context of a strong tobacco control environment like Thailand, secular norms about smoking becomes the dominant force.

Lower to Middle Cretaceous red sandstones were sampled at four localities in the Lanpin-Simao fold belt of the Shan-Thai Block to describe its regional deformational features. Most of the samples revealed a characteristic remanent magnetization with unblocking temperatures around 680 °C. Primary natures of magnetization are ascertained through positive fold test. A tilt-corrected formation-mean direction for the Jingdong (24.5°N, 100.8°E) locality, which is located at a distance of 25 km from the Ailaoshan-Red River Fault, revealed northerly declination with steep inclination (Dec./Inc. = 8.3°/48.8°, α95 = 7.7°, N = 13). However, mean directions obtained from the Zhengyuan (24.0°N, 101.1°E), West Zhengyuan (24.0°N, 101.1°E) and South Mengla (21.4°N, 101.6°E) localities indicate an easterly deflection in declination; such as Dec./Inc. = 61.8°/46.1°, α95 = 8.1° (N = 7), Dec./Inc. = 324.2°/-49.4°, α95 = 6.4° (N = 4) and Dec./Inc. = 51.2°/46.4°, α95 = 5.6° (N = 13), respectively. The palaeomagnetic directions obtained from these four localities are incorporated into a palaeomagnetic database for the Shan-Thai Block. When combined with geological, geochronological and GPS data, the processes of deformation in the Shan-Thai Block is described as follows: Subsequent to its rigid block clockwise rotation of about 20° in the early stage of India-Asia collision, the Shan-Thai Block experienced a coherent but southward displacement along the Red River Fault prior to 32 Ma. This block was then subjected to a north-south compressive stresses during the 32-27 Ma period, which played a key role in shaping the structure of Chongshan-Lancang-Chiang Mai Belt. Following this some local clockwise rotational motion has occurred during the Pliocene-Quaternary time in central part of the Shan-Thai Block as a result of internal block movements along the reactivated network of faults.

This qualitative study explores the perceptions of parents and adolescents toward sexual risk-taking behaviors. In-depth interviews were conducted with 30 parents and 30 adolescents (aged 13–14 years) in Bangkok, and were analyzed by using coding and thematic analysis. The results showed that although parents generally believed that Thai teens begin to have sex at an early age and engage in sexual risk-taking behaviors, they trusted that their teens would follow parental guidance and rules and not engage in sexual activity at this age. Most of the Thai teens in the present study reported that their parents were not really aware of their sexual behaviors because of their tendency to keep their sexual stories secret for fear of being scolded, blamed, and punished. The teens also reported that they wanted their parents to listen, give them warmth and more freedom, and be more in touch with their activities. Parents expressed their need for knowledge and skills so that they could help guide their adolescent children to avoid sexual risk-taking behaviors. A family intervention specifically aimed at empowering Thai urban parents is needed. PMID:22950618

Rhineland leadership practices contrast sharply with the prevailing Anglo/US business model of short-term maximization of profitability, and are said to lead to greater corporate sustainability, at least in highly developed economies. However, the applicability of Rhineland leadership to less developed economies has not yet been demonstrated. This paper sets out to compare the business practices of a social enterprise that delivers healthcare services in Thailand and Avery's 19 sustainable leadership practices derived from Rhineland enterprises. Adopting a case study approach, multi-data collection methods included non-participant observations made during visits to the enterprise, and reference to internal and published documentation and information. Semi-structured interview sessions were held with many stakeholders, including top management, staff, patients and a former consultant. In the Thai healthcare organization studied, evidence was found for compliance with 15 of Avery's 19 sustainable leadership elements, but to varying degrees. The elements were grouped into six core sets of practices: adopting a long-term perspective, staff development, organizational culture, innovation, social responsibility, and ethical behavior. One element was found to be not applicable, and no evidence was found for conformity with Rhineland principles on the remaining three sustainable practices. The paper concludes that Avery's 19 Rhineland practices provide a useful framework for evaluating the corporate sustainability of this Thai enterprise. Healthcare enterprises in Thailand and possibly in other Asian countries that wish to sustain their organizational success could adopt Avery's 19 Sustainable Leadership Grid elements to examine their leadership practices, and adjust them to become more sustainable. The relevance of Rhineland sustainable leadership principles to enterprises in less developed economies remains to be investigated. This study attempts to uncover this unknown.

Six known genes responsible for maturity-onset diabetes of the young (MODY) were analysed to evaluate the prevalence of their mutations in Thai patients with MODY and early-onset type 2 diabetes. Fifty-one unrelated probands with early-onset type 2 diabetes, 21 of them fitted into classic MODY criteria, were analysed for nucleotide variations in promoters, exons, and exon-intron boundaries of six known MODY genes, including HNF-4alpha, GCK, HNF-1alpha, IPF-1, HNF-1beta, and NeuroD1/beta2, by the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) method followed by direct DNA sequencing. Missense mutations or mutations located in regulatory region, which were absent in 130 chromosomes of non-diabetic controls, were classified as potentially pathogenic mutations. We found that mutations of the six known MODY genes account for a small proportion of classic MODY (19%) and early-onset type 2 diabetes (10%) in Thais. Five of these mutations are novel including GCK R327H, HNF-1alpha P475L, HNF-1alphaG554fsX556, NeuroD1-1972 G > A and NeuroD1 A322N. Mutations of IPF-1 and HNF-1beta were not identified in the studied probands. Mutations of the six known MODY genes may not be a major cause of MODY and early-onset type 2 diabetes in Thais. Therefore, unidentified genes await discovery in a majority of Thai patients with MODY and early-onset type 2 diabetes.

Hemoglobin (Hb) D. Punjab [β121(GH4) Glu→Gln; HBB: C.364G>C] and β0-thalassemia 3.4 kb deletion are very rare in the Thai population. For the first time, the coinheritance of HbD-Punjab with β0-thalassemia 3.4 kb deletion was reported in a 7-year-old Thai girl. She had mild anemia (Hb 115.0 g/L and mean corpuscular hemoglobin 18.1 pg) with red blood cell microcytosis (mean corpuscular volume 52.5 fL). By capillary electrophoresis (CE), HbD-Punjab was found at a migration position of 180 s with the value of 81.9% while the level of HbA2 was 7.3%. Based on the elevated HbA2, the molecular analysis for detection of β0-thalassemia mutations was performed. The 490 bp amplified fragments from β0-thalassemia 3.4 kb deletion was observed. Thus, the coinheritance of HbD-Punjab with β0-thalassemia can be found in the Thai population. The HbA2 measured on CE is a reliable parameter for differentiating the homozygote of HbD-Punjab and compound heterozygote of HbD-Punjab and β0-thalassemia. PMID:28970692

We previously showed that a combination of image thresholding, chain coding, elliptic Fourier descriptors, and artificial neural network analysis provided a low false acceptance rate (FAR) and a false rejection rate (FRR) of 11.0% and 19.0%, respectively, in identify Thai jasmine rice from three unwanted rice varieties. In this work, we highlight that only a polynomial function fitting on the determined chain code and the neural network analysis are highly sufficient in obtaining a very low FAR of < 3.0% and a very low 0.3% FRR for the separation of Thai jasmine rice from Chainat 1 (CNT1), Prathumtani 1 (PTT1), and Hom-Pitsanulok (HPSL) rice varieties. With this proposed approach, the analytical time is tremendously suppressed from 4,250 seconds down to 2 seconds, implying extremely high potential in practical deployment.

Student-centred forms of learning have gained favour internationally over the last few decades including problem based learning, an approach now incorporated in medicine, nursing and other disciplines' education in many countries. However, it is still new in Thailand and being piloted to try to offset traditional forms of didactic, teacher-centred forms of teaching. In this qualitative study, 25 undergraduate nursing students in northern Thailand were interviewed about their experiences with problem-based learning in a health promotion subject. Content analysis was used to interrogate interview data, which revealed four categories: adapting, seeking assistance, self-development, and thinking process development. Initially participants had mixed emotions of confusion, negativity or boredom in the adaption process, but expressed satisfaction with creativity in learning, group work, and leadership development. They described increased abilities to problem solve and think critically, but struggled to develop questioning behaviours in learning. Socio-culturally in Thai education, students have great respect for teachers, but rarely question or challenge them or their learning. We conclude that problem-based learning has great potential in Thai nursing education, but educators and systems need to systematically prepare appropriate learning environments, their staff and students, to incorporate this within curricula.

2017-06-01

Consequence assessment of a hypothetical severe accident is one of the important elements of the risk assessment of a nuclear power plant. It is widely known that the meteorological conditions can significantly influence the outcomes of such assessment, since it determines the results of the calculation of the radionuclide environmental transport. This study aims to assess the impacts of the meteorological conditions to the results of the consequence assessment. The consequence assessment code, OSCAAR, of Japan Atomic Energy Agency (JAEA) is used for the assessment. The results of the consequence assessment using Thai meteorological data are compared with those using Japanese meteorological data. The Thai case has following characteristics. Low wind speed made the radionuclides concentrate at the center comparing to the Japanese case. The squalls induced the peaks in the ground concentration distribution. The evacuated land is larger than the Japanese case though the relocated land is smaller, which is attributed to the concentration of the radionuclides near the release point.

The use of herbal products continues to expand rapidly across the world and concerns regarding the safety of these products have been raised. In Thailand, Thai Vigibase, developed by the Health Product Vigilance Center (HPVC) under the Thai Food and Drug Administration, is the national database that collates reports from health product surveillance systems and programmes. Thai Vigibase can be used to identify signals of adverse events in patients receiving herbal products. The purpose of the study was to describe the characteristics of reported adverse events in patients receiving herbal products in Thailand. Thai Vigibase data from February 2000 to December 2008 involving adverse events reported in association with herbal products were used. This database includes case reports submitted through the spontaneous reporting system and intensive monitoring programmes. Under the spontaneous reporting system, adverse event reports are collected nationwide via a national network of 22 regional centres covering more than 800 public and private hospitals, and health service centres. An intensive monitoring programme was also conducted to monitor the five single herbal products listed in the Thai National List of Essential Medicines (NLEM), while another intensive monitoring programme was developed to monitor the four single herbal products that were under consideration for inclusion in the NLEM. The database contained patient demographics, adverse events associated with herbal products, and details on seriousness, causality and quality of reports. Descriptive statistics were used for data analyses. A total of 593 reports with 1868 adverse events involving 24 different products were made during the study period. The age range of individuals was 1-86 years (mean 47 years). Most case reports were obtained from the intensive monitoring programme. Of the reports, 72% involved females. The herbal products for which adverse events were frequently reported were products containing

Antiestrogenic compounds were investigated from Thai indigenous plants for galactogogues since estrogen is reported to suppress lactation in breastfeeding women. The aerial parts of the Thai medicinal plant Capparis flavicans, which has traditionally been used to promote lactation, gave the new compound capparoside A (1), along with 28 known compounds. The leaves of Vitex glabrata belong to the same genus as the chaste tree (Vitex agnus-castus), which is used traditionally to support lactation, and afforded the new compounds khainaoside A (14), khainaoside B (15), and khainaoside C (16), together with six known compounds. The isolates were tested for their biological activity using the estrogen-responsive human breast cancer cell lines MCF-7 and T47D. Syringaresinol (3) and principin (6), from C. flavicans, and khainaoside A (14) showed the most potent inhibitory effects on estrogen-enhanced cell proliferation among all compounds isolated. These results suggest that the lactation-promoting properties of C. flavicans might be related to the inhibitory effect on excess estrogen of women who experience insufficient breastfeeding and highlight the possibility of using V. glabrata leaves for their antiestrogenic properties.

This study reports the antioxidant and antibacterial activities of four fresh mango seed extracts from Thai varieties. Total phenol contents determined by the Folin-ciocalteu method revealed the highest values to be in MKE, Chok-a-nan variety (399.8 mgGAE/g extract) and MSE of Nam-dok-mai variety (377.2 mgGAE/g extract). Both extracts showed potent ABTS˙+ radical and DPPH˙ radical scavenging activities with the lower half inhibition concentration (IC50) values than those of the reference compounds; vitamin C, trolox and BHA, respectively. Their antioxidant property of MSE and MKE is strongly correlated with the total phenol contents (r=0.98 and 0.98, respectively). When combined the MSE and MKE of the Fah-lun variety showed the strongest antioxidant activity. All mango seed extracts showed interesting antibacterial activity against both gram positive and gram negative bacteria as determined by disc diffusion method. The most sensitive pathogenic strain inhibited by all extracts (especially Kaew variety) was Pseudomonas aeruginosa ATCC 27853. This work suggests potential applications for practical uses of mango seed extracts from Thai varieties, as sources of antioxidant and antibacterial agents.

Thai/Lanna region has its own folklore wisdoms including the traditional medicinal plant recipes. Thai/Lanna medicinal plant recipe database "MANOSROI III" has been developed by Prof. Dr. Jiradej Manosroi. It consists of over 200,000 recipes for all diseases including cancer. To investigate the anti-proliferative and apoptotic activities on human colon cancer cell line (HT-29) as well as the cancer cell selectivity of the methanolic extracts (MEs) and fractions of the 23 selected plants from the "MANOSROI III" database. The 23 selected plants were extracted with methanol under reflux and evaluated for their anti-proliferative activity by sulforhodamine B assay. The 5 plants (Gloriosa superba, Caesalpinia sappan, Fibraurea tinctoria, Ventilago denticulata and Psophocarpus tetragonolobus) with potent anti-proliferative activity were fractionated by liquid-liquid partition to give 4 fractions including each hexane (HF), methanol-water (MF), n-butanol (BF) and water (WF) fractions. They were tested for anti-proliferative activity and cancer cell selectivity. The ME and fractions of G. superba which showed potent anti-proliferative activity were further examined for morphological changes and apoptotic activities by acridine orange (AO)/ethidium bromide (EB) staining. The ME of G. superba root showed active with the highest anti-proliferative activity at 9.17 and 1.58 folds of cisplatin and doxorubicin, respectively. After liquid-liquid partition, HF of V. denticulata, MFs of F. tinctoria, V. denticulata and BF of P. tetragonolobus showed higher anti-proliferative activities than their MEs. The MF of G. superba indicated the highest anti-proliferative activity at 7.73 and 1.34 folds of cisplatin and doxorubicin, respectively, but only 0.86 fold of its ME. The ME and HF, MF and BF of G. superba and MF of F. tinctoria demonstrated high cancer cell selectivity. At 50 µg/ml, ME, HF, MF and BF of G. superba demonstrated higher apoptotic activities than the two standard drugs

Empirical evidence demonstrates that the Thai Universal Coverage Scheme (UCS) has improved equity of health financing and provided a relatively high level of financial risk protection. Several UCS design features contribute to these outcomes: a tax-financed scheme, a comprehensive benefit package and gradual extension of coverage to illnesses that can lead to catastrophic household costs, and capacity of the National Health Security Office (NHSO) to mobilise adequate resources. This study assesses the policy processes related to making decisions on these features. The study employs qualitative methods including reviews of relevant documents, in-depth interviews of 25 key informants, and triangulation amongst information sources. Continued political and financial commitments to the UCS, despite political rivalry, played a key role. The Thai Rak Thai (TRT)-led coalition government introduced UCS; staying in power 8 of the 11 years between 2001 and 2011 was long enough to nurture and strengthen the UCS and overcome resistance from various opponents. Prime Minister Surayud's government, replacing the ousted TRT government, introduced universal renal replacement therapy, which deepened financial risk protection.Commitment to their manifesto and fiscal capacity pushed the TRT to adopt a general tax-financed universal scheme; collecting premiums from people engaged in the informal sector was neither politically palatable nor technically feasible. The relatively stable tenure of NHSO Secretary Generals and the chairs of the Financing and the Benefit Package subcommittees provided a platform for continued deepening of financial risk protection. NHSO exerted monopsonistic purchasing power to control prices, resulting in greater patient access and better systems efficiency than might have been the case with a different design.The approach of proposing an annual per capita budget changed the conventional line-item programme budgeting system by basing negotiations between the

From our previous nutritional assessment, low potassium (K) intake among northeastern Thai males has been clearly demonstrated. This prompted us to undertake a survey of the K content of local foods. Food samples comprised of 57 animal and 142 plant products which were collected from various places in the northeast of Thailand. The dry ashing method was used to prepare the samples for K analysis using an atomic absorption spectrophotometer. Foods could be divided into 7 groups according to their K levels. Foods containing K > or = 1000 mg per 100 g fresh food were categorized in group 1. These were mainly foods in the legume group, i.e., soybean, cowpea and mungbean. While rice (polished) and rice products, the main staple, were in group 7, the lowest K group of less than 100 mg per 100 g fresh food. Comparison studies of the natural foods between those collected from the northeast and from the central regions of the country, and between the cooked foods purchased from the rural villages and from the urban areas of Khon Kaen municipality, showed that, for most food items, the K content was similar wherever it came from. However, when the K content in various parts or in different stages of growth of the same kind of plants or animals was compared, a great variation was clearly seen, for example, young tamarind leaves contained K in group 6 whereas ripe tamarind fruit contained K in group 1. According to our food consumption data, the analysis of food components of 48 meals taken during the hot season by 13 rural volunteers revealed that food items eaten with the highest frequencies and in the largest amount were those in the low K food groups, i.e., glutinous rice (group 7) and green papaya (group 6). Our results suggest that the low K intake of these northeast rural Thai people is not due to a low K content of foods in this region, but rather that their food habits and low socioeconomic status restricts consumption of those food items with higher K contents.

This study was undertaken to investigate the effects of green tea on weight reduction in obese Thais. A randomized, controlled trial involving 60 obese subjects (body mass index, BMI > 25 kg/m2) was conducted. All subjects consumed a Thai diet containing 3 meals (8373.6 kJ/day) for 12 weeks, prepared by the Nutritional Unit at Srinagarind Hospital. The diet contained 65% carbohydrates, 15% protein, and 20% fat. Body weight, BMI, body composition, resting energy expenditure, and substrate oxidation were measured at baseline, and during weeks 4, 8, and 12 of the study. Serum levels of leptin and urine VMA were measured at baseline and during the 12th week. Differences over time and between the treatments (green tea or placebo) over time were determined using two-factor ANOVA with repeated measures. In comparing the two groups, differences in weight loss were 2.70, 5.10, and 3.3 kg during the 4th, 8th, and 12th weeks of the study, respectively. At the 8th and 12th weeks of the study, body weight loss was significantly different (P < 0.05). At the 8th week, the difference in resting energy expenditure was 183.38 kJ/day (P < 0.001), the difference in the respiratory quotient was 0.02 (P < 0.05), and no significant differences existed in satiety score, food intake, or physical activity. Urine VMA was significantly different in the 12th week of the study (P < 0.05). We conclude that green tea can reduce body weight in obese Thai subjects by increasing energy expenditure and fat oxidation.

Thai and American doctors on medical ethics: religion, regulation, and moral reasoning across borders.

Grol-Prokopczyk, Hanna

2013-01-01

Recent scholarship argues that successful international medical collaboration depends crucially on improving cross-cultural understanding. To this end, this study analyzes recent writings on medical ethics by physicians in two countries actively participating in global medicine, Thailand and the United States. Articles (133; published 2004-2008) from JAMA, the New England Journal of Medicine, and the Journal of the Medical Association of Thailand are analyzed to inductively build a portrait of two discursive ethical cultures. Frameworks of moral reasoning are identified across and within the two groups, with a focus on what authority (religion, law, etc.) is invoked to define and evaluate ethical problems. How might similarities and differences in ethical paradigms reflect the countries' historical "semicolonial" relationship, shed light on debates about Eastern vs. Western bioethics, and facilitate or hinder contemporary cross-national communication? Findings demonstrate substantial overlap in Thai and American doctors' vocabulary, points of reference, and topics covered, though only Thai doctors emphasize national interests and identity. American authors display a striking homogeneity in styles of moral reasoning, embracing a secular, legalistic, deontological ethics that generally eschews discussion of religion, personal character, or national culture. Among Thai authors, there is a schism in ethical styles: while some hew closely to the secular, deontological model, others embrace a virtue ethics that liberally cites Buddhist principles and emphasizes the role of doctors' good character. These two approaches may represent opposing reactions-assimilation and resistance, respectively-to Western influence. The current findings undermine the stereotype of Western individualism versus Eastern collectivism. Implications for cross-national dialog are discussed. Copyright © 2012 Elsevier Ltd.

Celiac disease (CD) and gluten-related disorders are significant health and social issues in Western countries, and CD individuals need to exclude gluten from their diets. The adverse health impacts of CD have extended to Asian countries in which CD was not a problem previously. Thai commercial food products that do not contain wheat, rye, barley, or gluten on their labels were surveyed as to whether they were suitable for CD individuals by examining the absence of gluten or the presence of gluten <20 ppm. In Thailand, ELISA tested for gluten content in 129 commercial food products that contained neither wheat, rye, barley, nor gluten on their labels. One hundred nineteen of these 129 products included <20 ppm gluten, and 10 products contained >20 ppm gluten. Surprisingly, four products showed gluten levels >1%. In these 10 products, wheat presence was confirmed by PCR analysis. Our survey suggests that CD individuals can consume most of the examined Thai food products, and the survey showed the potential of these Thai products as new diets for CD patients so as to expand the limited food choices from different food cultures, and ultimately to improve the quality of life for all CD individuals globally. The appropriate gluten management strategies need to be implemented by Thai food manufacturers to ensure accurate labeling and to protect the safety of consumers with CD.

Mycotoxin contamination in rice is less reported, compared to that in wheat or maize, however, some Fusarium fungi occasionally infect rice in the paddy field. Fumonisins are mycotoxins mainly produced by Fusarium verticillioides, which often ruins maize. Rice adherent fungus Gibberella fujikuroi is taxonomically near to F. verticillioides, and there are sporadic reports of fumonisin contamination in rice from Asia, Europe and the United States. Therefore, there exists the potential risk of fumonisin contamination in rice as well as the need for the validated analytical method for fumonisins in rice. Although both natural and spiked reference materials are available for some Fusarium mycotoxins in matrices of wheat and maize, there are no reference materials for Fusarium mycotoxins in rice. In this study, we have developed a method for the preparation of a reference material containing fumonisins in Thai rice. A ShakeMaster grinding machine was used for the preparation of a mixed material of blank Thai rice and F. verticillioides-infected Thai rice. The homogeneity of the mixed material was confirmed by one-way analysis of variance, which led this material to serve as an in-house reference material. Using this reference material, several procedures to extract fumonisins from Thai rice were compared. Accordingly, we proved the applicability of an effective extraction procedure for the determination of fumonisins in Japanese rice.

Kamcharean, Chanwit; Wattanakasiwich, Pornrat

The objective of this study was to diagnose misconceptions of Thai and Lao students in thermodynamics by using a two-tier multiple-choice test. Two-tier multiple choice questions consist of the first tier, a content-based question and the second tier, a reasoning-based question. Data of student understanding was collected by using 10 two-tier multiple-choice questions. Thai participants were the first-year students (N = 57) taking a fundamental physics course at Chiang Mai University in 2012. Lao participants were high school students in Grade 11 (N = 57) and Grade 12 (N = 83) at Muengnern high school in Xayaboury province, Lao PDR. As results, most students answered content-tier questions correctly but chose incorrect answers for reason-tier questions. When further investigating their incorrect reasons, we found similar misconceptions as reported in previous studies such as incorrectly relating pressure with temperature when presenting with multiple variables.

This study applies the model analysis technique to explore the distribution of Thai students’ attitudes and approaches to physics problem solving and how those attitudes and approaches change as a result of different experiences in physics learning. We administered the Attitudes and Approaches to Problem Solving (AAPS) survey to over 700 Thai university students from five different levels, namely students entering science, first-year science students, and second-, third- and fourth-year physics students. We found that their inferred mental states were generally mixed. The largest gap between physics experts and all levels of the students was about the role of equations and formulas in physics problem solving, and in views towards difficult problems. Most participants of all levels believed that being able to handle the mathematics is the most important part of physics problem solving. Most students’ views did not change even though they gained experiences in physics learning.

The English version of the Systemic Lupus Erythematosus Quality of Life Questionnaire (SLEQOL) is a validated disease-specific quality of life instrument. The aim of this study was to evaluate the psychometric properties of the Thai version of the SLEQOL (SLEQOL-TH). Two independent translators translated the SLEQOL into Thai. The back translation of this version was performed by two other independent translators. The final version, SLEQOL-TH, was completed after resolving the discrepancies revealed by the back translation. One hundred and nine patients with SLE were enrolled to test the reliability, construct validity, floor and ceiling effects, and sensitivity to the changes of the SLEQOL-TH at six months. The differential item functioning (DIF) between the Thai and English versions was analyzed using the partial gamma. The internal consistency of the SLEQOL-TH was satisfactory with the overall Cronbach's alpha of 0.86. The test-retest reliability of the SLEQOL-TH was acceptable with the intra-class correlation coefficient of 0.86. Low correlations between the SLEQOL-TH and SLEDAI were observed. The total score of the SLEQOL-TH was moderately responsive to changes in quality of life, with a standardized response mean of 0.50. When comparing the SLEQOL-TH from Thai SLE patients with the original SLEQOL version obtained from Singapore SLE patients, 11 out of 40 items showed a moderate to large DIF. The SLEQOL-TH has acceptable psychometric properties and shows construct validity. In comparison with the English version of SLEQOL, there are some items that showed DIF. The applicability of the SLEQOL-TH in real-life clinical practice and clinical trials needs to be determined.

More than 11 million Thai people (38%) work in agriculture, but since most are in the informal sector, government enforcement and support are very limited. As a result, working conditions on Thai farms vary greatly, putting the health of many agricultural workers at risk. A cross-sectional study in three Thai provinces collected information on the work activities and conditions of 424 farmers representing five farm types: rice, vegetable, flower, rice/vegetable, and flower/vegetable. The agricultural workers were mainly women (60%); their average age was 53 but ranged from 18 to 87 years. More than 64% worked more than 5 days/week. Seventy-four percent of them had only primary school education. A number of the health and hazardous working conditions surveyed were significantly different by farm type. Rice farmers were found to have the highest prevalence of allergies, nasal congestion, wheezing, and acute symptoms after pesticide use, while flower farmers had the lowest prevalence of these health outcomes. Rice farmers reported the highest prevalence of hazardous working conditions including high noise levels, working on slippery surfaces, sitting or standing on a vibrating machine, spills of chemicals/pesticides, and sharp injuries. The lowest prevalence of these working conditions (except noise) was reported by flower farmers. Vegetable farmers reported the highest prevalence knee problems, while rice farmers had the lowest prevalence. Among these farmers, more than 27 different types of pesticides were reported in use during the past year, with the majority reporting use once a month. The flower/vegetable farming group reported the highest frequency of good exposure prevention practices during pesticide use. They were the most likely to report using cotton or rubber gloves or a disposable paper masks during insecticide spraying. Those farmers who only grew vegetables had the lowest frequency of good exposure prevention practices, including use of personal

There are limited data for age at menopause (AM) and menopause-related symptoms in human immunodeficiency virus (HIV)-infected Asian women. We investigated AM and menopause-related symptoms in HIV-infected Thai women. HIV-infected Thai women 40 years or older who did not receive any hormone therapy in the 8-week period preceding the study were enrolled. Participants completed the Menopause-Specific Quality of Life survey for their symptoms in the past 30 days. Menopause was defined as having the last menstrual period more than 1 year ago. Multivariate Cox proportional hazard regression analysis was used to identify factors associated with menopause. Two hundred sixty-eight HIV-infected women were enrolled; their median age was 44.6 (41.8-48.7) years, and the ratio of their Centers for Disease Control and Prevention clinical classifications (A:B:C) was 53%:34%:13%; 95% were using highly active antiretroviral therapy. The median (interquartile range [IQR]) CD4 count was 575 (437-758) cells/μL, and 93% had HIV-RNA of less than 1.7log10 copies/mL. Among the 55 women who had reached menopause, the mean (SD) AM was 47.3 (5.1) years. The mean (SD) AM in our study was earlier than the previous report of 49.5 (3.6) years in non-HIV-infected Thai women (difference, -2.2 y; 95% CI, -3.2 to -1.2, P < 0.01). Postmenopausal women had more symptoms, including night sweats (P = 0.03), change in sexual desire (P = 0.01), and avoiding intimacy (P = 0.01), compared with nonpostmenopausal women. No differences in psychosocial or physical domains between groups were found. Factors associated with menopause were Centers for Disease Control and Prevention clinical classification B or C (hazard ratio, 1.7; 95% CI, 1.0-3.03, P = 0.04), and no sexual act in the past month (hazard ratio, 4.9; 95% CI, 1.5-16.0, P = 0.01). No associations of later age of menarche, parity, marital status, educational level, income, body mass index, CD4 count, and HIV-RNA with menopause were found. AM in HIV

This study assessed the impact of the Thai-US Free Trade Agreement (FTA) on access to medicines in Thailand. We first interpreted the text of the sixth round of Thai-US negotiations in 2006 on intellectual property rights (IPR). The impact was estimated using a macroeconomic model of the impact of changes in IPR. The estimated impact is based on a comparison between the current IPR situation and the proposed changes to IPR. The FTA text involves the period of patent extension from the Trade-Related Aspects of Intellectual Property Rights Agreement (TRIPS Agreement). The provisions involve the period of patent extension, which have to do with compensation for delays in patent registration and/or drug registration, data exclusivity that would result in a delay in generic drug entry, and the enforcing role of the Thai Food and Drug Administration of patent linkages. As a worst case scenario for this single provision, a 10 year patent extension would be given to compensate for delays in patent registration and/or drug registration. The impact on access to medicine, in the year 2027, would be: 1) A 32% increase in the medicine price index, 2) spending on medicines would increase to approximately USD 11,191 million, (USD1 = THB 33.9 on September 2, 2009), and 3) the domestic industry could loss USD 3.3 million. These results suggest there would be a severe restriction on the access to medicines under the TRIPS-Plus proposal. IPR protection of pharmaceuticals per the TRIPS-Plus proposal should be excluded from FTA negotiations.

The study aimed to evaluate the reliability and validity of the Thai version of the Pediatric Quality of Life Inventory™ 4.0 Core Scales (PedsQL) as a measure of health-related quality of life (HRQOL). The PedsQL items were completed by 2,086 pupils aged 8-15 years and 1,914 parents from four schools, and 100 pediatric outpatients and 100 parents from a University Hospital. Test-retest reliability was conducted in a randomly selected of 150 pupils at a 1-month interval. Internal consistency reliability for the Total Scale score (α = 0.84 self-report, 0.88 proxy-report), Physical Health Summary score (α = 0.76 self-report, 0.79 proxy-report), and Psychosocial Health Summary score (α = 0.74 self-report, 0.85 proxy-report) exceeded the minimum reliability standard of 0.70. School children had significantly higher mean HRQOL scores compared to those with chronic health conditions for all subscales with the mean differences of 3.1-12.4 for self-report (p < 0.03) and 7.7-15.6 for proxy-report (p < 0.001). Test-retest reliability showed intraclass correlation coefficients above 0.60 in all subscales (p < 0.001). The Thai version of PedsQL had adequate reliability and validity and could be used as an outcome measure of HRQOL in Thai children aged 8-15 years.

Ultraviolet radiation from sunlight induces overproduction of reactive oxygen species (ROS) resulting in skin photoaging and hyperpigmentation disorders. Novel whitening and anti-wrinkle compounds from natural products have recently become of increasing interest. The purpose of this study was to find products that reduce ROS in 14 Thai plant extracts. To determine total phenolic and flavonoid content, antioxidant activity, anti-tyrosinase activity and anti-collagenase activity, we compared extracts of 14 Thai plants prepared using different solvents (petroleum ether, dichloromethane and ethanol). Antioxidant activities were determined by DPPH and ABTS assays. Total phenolic content of the 14 Thai plants extracts was found at the highest levels in ethanol followed by dichloromethane and petroleum ether extracts, respectively, while flavonoid content was normally found in the dichloromethane fraction. Scavenging activity ranged from 7 to 99% scavenging as assessed by DPPH and ABTS assays. The ethanol leaf extract of Ardisia elliptica Thunb. had the highest phenolic content, antioxidant activity and collagenase inhibition, while Cassia alata (L.) Roxb. extract had the richest flavonoid content. Interestingly, three plants extracts, which were the ethanolic fractions of Annona squamosa L., Ardisia elliptica Thunb. and Senna alata (L.) Roxb., had high antioxidant content and activity, and significantly inhibited both tyrosinase and collagenase. Our finding show that the ethanol fractions of Annona squamosa L., Ardisia elliptica Thunb. and Senna alata (L.) Roxb. show promise as potential ingredients for cosmetic products such as anti-wrinkle agents and skin whitening products.

Despite known health risks related to the use of powdered latex gloves (PLGs), they are still widely used in hospitals in developing countries due to the high cost of alternatives. To determine the prevalence of dermal and respiratory symptoms associated with latex glove use in nurses in Thailand and evaluate the influence of previously reported occupational risk factors in this population. A cross-sectional study in female nurses working in three Thai hospitals. Participants completed a questionnaire on demographics, occupational and personal history, use of latex products at work and dermal and respiratory symptoms attributed to occupational use of latex gloves. Of 899 nurses, 18% reported health effects attributed to the use of latex products. After adjustment for confounding, occupational risk factors associated with increased reporting of dermal symptoms included wearing more than 15 pairs of PLG per day (odds ratio (OR): 2.10, 95% confidence interval (CI): [1.32-3.34]), using chlorhexidine (OR: 2.07, 95% CI: [1.22-3.52]) and being an operating theatre nurse (OR: 2.46, 95% CI: [1.47-4.12]). Being a labour ward nurse (OR: 3.52, 95% CI: [1.26-9.85]) was the only factor associated with increased reporting of respiratory symptoms. Continuing use of PLGs in Thai nurses is associated with increased prevalence of dermal symptoms compared with data from developed countries. Measures to reduce such health effects are well established and should be considered. Additionally, replacement of chlorhexidine with an alternative detergent seems advisable.

In this study, 34 yeast isolates were obtained from koji and moromi samples of Thai soy sauce fermentation. However, the most interesting yeast strain was isolated from the enriched 2 month-old (M2) moromi sample and identified as Meyerozyma (Pichia) guilliermondii EM2Y61. This strain is a salt-tolerant yeast that could tolerate up to 20% (w/v) NaCl and produce extracellular and cell-bound glutaminases. Interestingly, its glutaminases were more active in 18% (w/v) NaCl which is a salt concentration in moromi. The extracellular glutaminase's activity was found to be much higher than that of cell-bound glutaminase. The highest specific activity and stability of the extracellular glutaminase were found in 18% (w/v) NaCl at pH4.5 and 37°C. A challenge test by adding partially-purified extracellular glutaminase from M. guilliermondii EM2Y61 into 1 month-old (M1) moromi sample showed an increased conversion of L-glutamine to L-glutamic acid. This is the first report of glutaminase producing M. guilliermondii isolated from the moromi of Thai soy sauce fermentation. The results suggested the potential application of M. guilliermondii EM2Y61 as starter yeast culture to increase l-glutamic acid during soy sauce fermentation. Copyright © 2014 Elsevier B.V.

The Magnetized Plasma Linear Experimental (MaPLE) device is a low cost laboratory plasma device at Saha Institute of Nuclear Physics fabricated in-house with the primary aim of studying basic plasma physics phenomena such as plasma instabilities, wave propagation, and their nonlinear behavior in magnetized plasma regime in a controlled manner. The machine is specially designed to be a versatile laboratory device that can provide a number of magnetic and electric scenario to facilitate such studies. A total of 36 number of 20-turn magnet coils, designed such as to allow easy handling, is capable of producing a uniform, dc magnetic field of about 0.35 T inside the plasma chamber of diameter 0.30 m. Support structure of the coils is planned in an innovative way facilitating straightforward fabrication and easy positioning of the coils. Further special feature lies in the arrangement of the spacers between the coils that can be maneuvered rather easily to create different magnetic configurations. Various methods of plasma production can be suitably utilized according to the experimental needs at either end of the vacuum vessel. In the present paper, characteristics of a steady state plasma generated by electron cyclotron resonance method using 2.45 GHz microwave power are presented. Scans using simple probe drives revealed that a uniform and long plasma column having electron density approximately 3-5x10(10) cm(-3) and temperature approximately 7-10 eV, is formed in the center of the plasma chamber which is suitable for wave launching experiments.

This study sheds light on obstacles to safe sexual health for young Thais and their need for appropriate sexual and reproductive health services. The study population was 1,745 unmarried adolescents aged 17-20 who resided or worked in Chiang Mai, the major city in northern Thailand. The study used quantitative and qualitative methods to explore the vulnerability of sexually active adolescents as well as the lack of support and care for them from parents and health providers. We found that young Thais still prefer pharmacies for self-medication and use government health care facilities as a last resort. Current health services are not suitable for young people in northern Thailand because they lack privacy and impose judgemental attitudes, especially towards sexually active adolescent females. Current programs for adolescent sexual and reproductive health focus on education and counselling and do not provide appropriate privacy or clinical care. There is a pressing need for advocacy, policy support for the development of youth-friendly sexual and reproductive health services in Thailand. PMID:23082599

2015-06-01

One-third of patients with epilepsy are resistant to anti-epileptic drugs (AEDs). Drug-resistant epilepsy is believed to be multifactorial involving both genetic and non-genetic factors. Genetic variations in the ABCB1 gene encoding the drug efflux transporter, p-glycoprotein (p-gp), may influence the interindividual variability in AED response by limiting drugs from reaching their target. Phenobarbital (PB), one of the most cost-effective and widely used AEDs in developing countries, has been reported to be transported by p-gp. This study aimed to investigate the association of a genetic variant, ABCB1 3435C>T, and non-genetic factors with phenobarbital response in Thai patients with epilepsy. One hundred and ten Thai patients with epilepsy who were treated with PB maintenance doses were enrolled in this study. Two phenotypic groups, PB-responsive epilepsy and PB-resistant epilepsy, were defined according to the International League Against Epilepsy (ILAE) criteria. Subjects were genotyped for ABCB1 3435C>T (rs1045642). Multiple logistic regression analysis was tested for the association of ABCB1 3435C>T polymorphism and non-genetic factors with PB response. Sixty-two PB-responsive epilepsy subjects and 48 PB-resistant epilepsy subjects were identified. All genotype frequencies of the ABCB1 3435C>T SNP were consistent with the Hardy-Weinberg equilibrium (P > 0·05). The ABCB1 3435C>T polymorphism and type of epilepsy were associated with response to PB. Patients with PB-resistant epilepsy had a significantly higher frequency of ABCB1 3435CC genotype and had focal epilepsy more often than patients with PB-responsive epilepsy (adjusted OR = 3·962, 95% CI = 1·075-14·610, P-value = 0·039; adjusted OR = 5·936, 95% CI = 2·272-15·513, P-value < 0·001, respectively). The model explained 25·5% of the variability in response to PB (R(2)  = 0·255). Thai patients of ABCB1 3435CC genotype and with focal epilepsy were more often PB resistant. Those two

The National Astronomical Research Institute of Thailand (NARIT) have launched the program "Advance Teacher Training Workshop" that aims to introduce both the students and astronomy teacher alike to the nature of critical thinking in science via hands on experience in astronomy projects. Students and accompanying teachers are participated in 5 days workshop in which each of them must select an individual astronomy research project. The project is then carried out on their own for the next 6 months, after which their works are presented in a conference. Progress is monitored and extra aid is delivered as needed via the use of social media. Over a hundred projects have been completed under this program. Follow up study have suggests that this workshop has shown to be quite successful at improving critical thinking skills in participants. As the program became more popular, other schools began to follow. To support the growing interest, we have also launched the "Thai Astronomical Society: student session", a highschool astronomy conference for anyone who participated or interested in astronomy related projects. Via these stages we are able to secure a permanent foothold in Thai astronomy education and inspire new generations to participate in astronomy projects.

Determination of melatonin content in traditional Thai herbal remedies used as sleeping aids

PubMed Central

2014-01-01

Background Melatonin content was screened in leaves of seven edible herbs used as sleeping aids in Thai traditional medicine. These plants are Piper nigrum L, Sesbania glandiflora (L.) Desv., Sesbania sesban (L.) Merr., Senna tora (L.) Roxb., Moringa oleifera Lam., Momordica charantia L. and Baccaurea ramiflora Lour. Dried leaves were extracted by sonication in methanol for six hours at room temperature, and then melatonin was purified by C18 solid phase extraction (SPE). Melatonin was then quantified by a validated RP-C18 HPLC method with fluorescent detection. Findings Melatonin contents in extracts of B. ramiflora, S. glandiflora, M. charantia, S. tora and S. sesban were 43.2, 26.3, 21.4, 10.5 and 8.7 ng/g of dry sample weight, respectively. The highest melatonin content was from P. nigrum extract (1092.7 ng/g of dry sample weight). Melatonin was not detected in the extract of M. oleifera. Melatonin identification was confirmed by ELISA. Conclusions Melatonin was found in six of the seven herbs in the traditional Thai sleeping recipe. One of these, P. nigrum, exhibited an encouragingly high amount of melatonin. PMID:24393215

Calibration-Free Laser-Induced Breakdown Spectroscopy (CF-LIBS) with Standard Reference Line for the Analysis of Stainless Steel.

PubMed

Fu, Hongbo; Dong, Fengzhong; Wang, Huadong; Jia, Junwei; Ni, Zhibo

2017-08-01

In this work, calibration-free laser-induced breakdown spectroscopy (CF-LIBS) is used to analyze a certified stainless steel sample. Due to self-absorption of the spectral lines from the major element Fe and the sparse lines of trace elements, it is usually not easy to construct the Boltzmann plots of all species. A standard reference line method is proposed here to solve this difficulty under the assumption of local thermodynamic equilibrium so that the same temperature value for all elements present into the plasma can be considered. Based on the concentration and rich spectral lines of Fe, the Stark broadening of Fe(I) 381.584 nm and Saha-Boltzmann plots of this element are used to calculate the electron density and the plasma temperature, respectively. In order to determine the plasma temperature accurately, which is seriously affected by self-absorption, a pre-selection procedure for eliminating those spectral lines with strong self-absorption is employed. Then, one spectral line of each element is selected to calculate its corresponding concentration. The results from the standard reference lines with and without self-absorption of Fe are compared. This method allows us to measure trace element content and effectively avoid the adverse effects due to self-absorption.

This study investigates cognitive and affective components of Japanese and Thai children's attitudes toward international political socialization. The survey results report how children feel about people from other nations, international political institutions, and their country's involvement with the world community. An important concern of the study is the assessment of how much accurate knowledge Japanese and Thai elementary school children have about other nations. This study includes information on children's feelings about, and knowledge of such problems as warfare between nations, world government, stereotypic thinking about people not belonging to one's own culture and awareness of cross-cultural diffusion between Japan, Thailand and other nations.

We measured plasma tafenoquine concentrations in Thai soldiers given a monthly regimen of tafenoquine to determine whether these concentrations adequately suppressed malarial infections on the Thai-Cambodian border. After receiving a treatment course of artesunate and doxycycline, 104 male soldiers were administered a loading dose of tafenoquine (400 mg daily for 3 days), followed by tafenoquine monthly (400 mg every 4 weeks) for 5 months. Consecutive monthly mean (+/- standard deviation) trough plasma tafenoquine concentrations were 223+/-41, 127+/-29, 157+/-51, 120+/-24, and 88+/-20 ng/mL. Only 1 soldier developed malaria during the study. At the time of malaria diagnosis, his plasma tafenoquine concentration was 40 ng/mL, which was approximately 3-fold lower than the trough concentrations of the other soldiers. Although low tafenoquine concentrations appear to be uncommon, additional investigations are needed to determine the relationship between plasma tafenoquine concentrations and suppression of malaria.

This study determines the prevalence of metabolic syndrome (MetS) according to the International Diabetes Federation (IDF) and National Cholesterol Education Program III (NCEP) criteria in Thai adults. Data from a national representative sample, InterASIA study, including a total of 5305 Thai adults 35 years and older were analyzed. Overall, the age-standardized prevalence of MetS by IDF and NCEP criteria were 24.0% (men 16.4%, women 31.6%) and 32.6% (men 28.7%, women 36.4%), respectively. The difference in prevalence of MetS between genders was much greater for the IDF compared with the NCEP definition. The age-standardized prevalence rates distributed by geographic region were relatively uniform with a lowest prevalence in the northeast. Among all possible sets of components for MetS, the most common combinations were a set of low high-density lipoprotein cholesterol, high triglyceride, and hyperglycemia in men (3.9%) and a set of abdominal obesity, low high-density lipoprotein cholesterol, and high triglycerides in women (6.7%). MetS is common in Thai adults and NCEP definition captures more cases of MetS compared with the IDF definition. Implementation of programs to prevent obesity and metabolic factors along with future periodic survey to monitor the problem is crucial.

Objectives. To study the cut-off point of Homeostatic Measurement Assessment-Insulin Resistance (HOMA-IR) as a screening test for detection of glucose intolerance in Thai women with polycystic ovary syndrome (PCOS). Study Design. Cross-sectional study. Setting. Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital. Subject. Two hundred and fifty Thai PCOS women who attended the Gynecologic Endocrinology Unit, during May 2007 to January 2009. Materials and Methods. The paitents were interviewed and examined for weight, height, waist circumference, and blood pressure. Venous blood samples were drawn twice, one at 12-hour fasting and the other at 2 hours after glucose loading. Results. The prevalence of glucose intolerance in Thai PCOS women was 20.0%. The mean of HOMA-IR was 3.53  ±  7.7. Area under an ROC curve for HOMA-IR for detecting glucose intolerance was 0.82. Using the cut-off value of HOMA-IR >2.0, there was sensitivity at 84.0%, specificity at 61.0%, positive predictive value at 35.0%, negative predictive value at 93.8%, and accuracy at 65.6%. Conclusion. HOMA-IR >2.0 was used for screening test for glucose intolerance in Thai PCOS women. If the result was positive, a specific test should be done to prove the diagnosis.

A biomechanical analysis of the roundhouse kicking technique of expert practitioners: A comparison between the martial arts disciplines of Muay Thai, Karate, and Taekwondo

PubMed Central

2017-01-01

The purpose of this study was first, to determine whether there were differences in the roundhouse kicking leg kinematics performed by highly skilled Muay Thai, Karate and Taekwondo practitioners (n = 8 per group). Next, analysis aimed to identify the kinematic determinants of effective roundhouse kicking performance. Three-dimensional (3D) lower limb kinematics were recorded using a nine camera infra-red motion capture system (500 Hz) during three maximal roundhouse kicks. Impact forces were recorded using a strain gauge (1000 Hz) attached to a kicking pad positioned at the height of each participant’s mastoid process. Results showed that linear foot velocity at impact was moderately correlated with relative impact force (r = 0.66, P = 0.001). Discipline specific analyses of the temporal data indicated that the Muay Thai group had a shorter execution time (1.02 ± 0.15 s) than Taekwondo (1.54 ± 0.52 s, P = 0.028). Analysis of lower limb kinematic data indicated that both Karate (-947 ± 94 deg/s, P = 0.010) and Taekwondo (-943 ± 106 deg/s, P = 0.011) practitioners had faster knee extension velocities than the Muay Thai group (-706 ± 200 deg/s). Conversely, the Muay Thai practitioners (1.24 ± 0.15 m/s) had greater vertical centre of mass movement than both Karate (0.78 ± 0.24 m/s, P = 0.001) and Taekwondo groups (0.93 ± 0.19 m/s, P = 0.02). Our findings show that several fundamental movement patterns were common to the roundhouse kicking techniques across the Muay Thai, Karate, and Taekwondo disciplines. Effective roundhouse kicking performance was characterized by rapid pelvic axial rotation, hip abduction, hip flexion and knee extension velocities, combined with rapid movements of the COM towards the target.

Piperaquine combined with dihydroartemisinin is one of the artemisinin derivative combination therapies, which can replace artesunate–mefloquine in treating uncomplicated falciparum malaria in Thailand. The aim of this study was to determine the in vitro sensitivity of Thai Plasmodium falciparum isolates against piperaquine and the influence of the pfmdr1 gene on in vitro response. One hundred and thirty-seven standard laboratory and adapted Thai isolates of P. falciparum were assessed for in vitro piperaquine sensitivity. Polymorphisms of the pfmdr1 gene were determined by polymerase chain reaction methods. The mean and standard deviation of the piperaquine IC50 in Thai isolates of P. falciparum were 16.7 ± 6.3 nM. The parasites exhibiting chloroquine IC50 of ≥ 100 nM were significantly less sensitive to piperaquine compared with the parasite with chloroquine IC50 of < 100 nM. No significant association between the pfmdr1 copy number and piperaquine IC50 values was found. In contrast, the parasites containing the pfmdr1 86Y allele exhibited significantly reduced piperaquine sensitivity. Before nationwide implementation of dihydroartemisinin–piperaquine as the first-line treatment in Thailand, in vitro and in vivo evaluations of this combination should be performed especially in areas where parasites containing the pfmdr1 86Y allele are predominant such as the Thai–Malaysian border.

2015-07-01

The microbial corrosion behavior of three important steels (carbon steel, stainless steel, and Corten steel) was investigated in semi petroleum medium. This work was done in modified nutrient broth (2 g nutrient broth in 1 L oily wastewater) in the presence of Pseudomonas aeruginosa and mixed culture (as a biotic media) and an abiotic medium for 2 weeks. The behavior of corrosion was analyzed by spectrophotometric and electrochemical methods and at the end was confirmed by scanning electron microscopy. The results show that the degree of corrosion of Corten steel in mixed culture, unlike carbon steel and stainless steel, is less than P. aeruginosa inoculated medium because some bacteria affect Corten steel less than other steels. According to the experiments, carbon steel had less resistance than Corten steel and stainless steel. Furthermore, biofilm inhibits separated particles of those steels to spread to the medium; in other words, particles get trapped between biofilm and steel.

Interactive laboratory class (ILC) is a two-way communication teaching method that encourages students to correlate laboratory findings with materials from lectures. In Thai medical education, active learning methods are uncommon. This paper aims to establish 1) if ILCs would effectively promote physiology learning; 2) if effectiveness would be found in both previously academically high-performing and low-performing students; and 3) the acceptability of ILCs to Thai medical students as a novel learning method. Two hundred seventy-eight second-year medical students were recruited to this study. We conducted three ILC sessions, which followed corresponding lectures. We carried out multiple-choice pre- and post-ILC assessments of knowledge and compared by repeated-measures ANOVA and unpaired t-test. Subgroup analysis was performed to compare high-performance (HighP) and low-performance (LowP) students. After the ILCs, participants self-rated their knowledge and satisfaction. Post-ILC test scores increased significantly compared with pre-ILC test scores in all three sessions. Mean scores of each post-ILC test increased significantly from pre-ILC test in both LowP and HighP groups. More students self-reported a "very high" and "high" level of knowledge after ILCs. Most students agreed that ILCs provided more discussion opportunity, motivated their learning, and made lessons more enjoyable. As an adjunct to lectures, ILCs can enhance knowledge in medical students, regardless of previous academic performance. Students perceived ILC as useful and acceptable. This study supports the active learning methods in physiology education, regardless of cultural context.

The Khon Mueang represent the major group of people present in today's northern Thailand. While linguistic and genetic data seem to support a shared ancestry between Khon Mueang and other Tai-Kadai speaking people, the possibility of an admixed origin with contribution from local Mon-Khmer population could not be ruled out. Previous studies conducted on northern Thai people did not provide a definitive answer and, in addition, have largely overlooked the distribution of paternal lineages in the area. In this work we aim to provide a comprehensive analysis of Y paternal lineages in northern Thailand and to explicitly model the origin of the Khon Mueang population. We obtained and analysed new Y chromosomal haplogroup data from more than 500 northern Thai individuals including Khon Mueang, Mon-Khmer and Tai-Kadai. We also explicitly simulated different demographic scenarios, developed to explain the Khon Mueang origin, employing an ABC simulation framework on both mitochondrial and Y microsatellites data. Our results highlighted a similar haplogroup composition of Khon Mueang and Tai-Kadai populations in northern Thailand, with shared high frequencies of haplogroups O-PK4, O-M117 and O-M111. Our ABC simulations also favoured a model in which the ancestors of modern Khon Mueang originated recently after a split from the other Tai-Kadai populations. Our different analyses concluded that the ancestors of Khon Mueang are likely to have originated from the same source of the other Tai-Kadai groups in southern China, with subsequent admixture events involving native Mon-Khmer speakers restricted to some specific populations.

Children and youth gain multiple health benefits from regular participation in physical activity (PA). However, in Thailand there is limited national data on children and youth's PA behaviors and recent reports suggest that Thai children and youth have low levels of PA. Furthermore, there is almost no data on the factors associated with inactivity to support the development of a Thai National PA Plan. The purpose of this paper is to investigate Thai children and youth's participation in PA and its correlates across sociodemographic characteristics and different PA domains. This study applied a cross-sectional study design with a multi-stage stratified cluster sampling. A national representative sample of 13,255 children and youth aged 6-17 years were used for data analysis. A previously validated questionnaire was used to assess PA prevalence. Logistic regression was conducted to examine the relationships of socio-demographic factors, and participation in different PA domains with overall PA. Only 23.4% of Thai children and youth met recommended levels of PA and there were large gender and regional differences. PA levels generally declined with age, although the level observed in the 10-13 year group was slightly higher than other year groups. A majority of children and youth engaged in a large number of different activities across PA domains. Sex, age, BMI, geographical regions, organized sports, participation in sport and recreational activities were significant predictors of meeting the global PA guidelines, whereas participation in physical education, active transport, and the number of screen time activities had no association. Girls were less likely to achieve sufficient PA levels (OR = 0.49, 95%CI; 0.45-0.54, p < 0.001), as were obese children (OR = 0.78, 95%CI; 0.64-0.94, p = 0.01), children living in the West (OR = 0.47, 95%CI; 0.38-0.59, p < 0.001), and those who did no participation in organized sports and sport/exercise activities, or

Plasma carnitine and urinary carnitine levels were measured in Thai adults living in Bangkok city and Ubol villages. The mean plasma carnitine and urinary carnitine levels expressed in micromoles per liter in Bangkok adults were higher than those in Ubol adults. Their mean plasma carnitine levels were 56.6 +/- 1.8 and 50.3 +/- 1.7 whereas urinary carnitine levels were 161 +/- 19 and 127 +/- 18 micromole/liter, respectively. The nutritional status in Ubol adults was inadequate. This was evidenced by the significant decrease in urinary creatinine excretion, serum albumin, and hematocrit levels. The dietary assessment agreed with the biochemical findings. Since rice, limiting in carnitine, was the main protein and energy source consumed by Ubol adults their inadequate carnitine status could be due to the low carnitine intake. Sex affects plasma carnitine levels in Bangkok adults and urinary carnitine excretion in both groups. This could be related to the lean body mass in which most of the body carnitine resides. This is supported by the higher urinary creatinine excretion in males and the significant positive correlation between carnitine excretion and creatinine-height index.

Acrylamide in Thai-conventional snacks was analysed by GC/MS with a linear response ranged of 5-50 µg and r² > 0.99. The limit of detection (s/n = 3) and limit of quantification (s/n = 10) were 4 and 15 µg kg⁻¹, respectively, and RSD < 2%. Acrylamide in 19 food samples ranged from <15 µg kg⁻¹ to 1.26 mg kg⁻¹ with highest concentrations in Kanom Jak. Moderate levels (150-500 µg kg⁻¹) were detected mostly in deep-fried products, especially sweet potato and taro crisps, Kanom Kai Hong, banana fritters, durian chips and spring rolls. Thai-conventional snacks possessed low concentrations (<150 µg kg⁻¹) including Khao Larm, Pa Tong Koo, sweet banana crisps and deep-fried Chinese wonton. Acrylamide was lowest (<15 µg kg⁻¹) in fish strips, rice crackers, Hoi Jor and fried fish balls. Dietary habits by 400 tourists indicate a daily intake of acrylamide <150 ng, well below a toxic dose.

This study aimed to determine Thais' knowledge of heart attack symptoms and risk factors and whether that knowledge was related to age, gender or education. Via a street-intercept survey method, a convenience sample of people aged ≥ 35 years (n = 192) was recruited. Mean age was 47 ± 9.6 years (range 35-81), and 55.2% were female. Participants identified on average 5.6 of 9 heart attack symptoms (SD 1.8) and 5.3 of 8 heart attack risk factors (SD 2.1). However, 66.7% mistakenly thought the chest discomfort would be severe, sharp and stabbing, and many subjects erroneously selected symptoms that are actually stroke symptoms. There were no gender or educational differences in knowledge of heart attack symptoms and risk factors. Older adults recognized fewer total symptoms than did younger adults. These findings could direct health-care providers to help the Thai population differentiate symptoms of heart attack from stroke. © 2010 Blackwell Publishing Asia Pty Ltd.

To study the relationship of lactose intolerance and intestinal villi morphology in Thai people. Subjects for this study were patients with functional dyspepsia who had no history of milk allergy and underwent gastroduodenoscopy. Two mucosal biopsy specimens were taken from beyond the distal end of the second part of the duodenum. The specimens were carefully orientated and were graded according to the following scheme: group I: finger shaped villi; group II: mixed finger and leaf shaped villi; group III: clubbing or blunting shaped villi. All subjects were tested for lactose malabsorption by breath hydrogen analysis after consuming 50 gram lactose. Breath hydrogen concentration was analyzed in samples collected intermittently by end-expiratory technique. A rise in breath hydrogen concentration of 20 PPM over baseline was considered evidence of lactose malabsorption. The twenty-five subjects were twenty females (80.0%) and five males (20.0%) who ranged in age from 18 to 53 years (mean 31 +/- 8.29). Sixteen subjects belonged to the finger shaped villi group (64.0%), five to the mixed finger and leaf shaped villi, group (20.0%) and four to the clubbing or blunting shaped villi group (16.0%). Results of breath hydrogen excretion test identified the prevalence of lactose intolerance in 68 per cent of the subjects: 15/16 (93.75%) of group I; 1/5 (20.0%) of group II and 1/4 (25%) of group III respectively (P<0.001). The symptom of diarrhea after lactose loading was correlated well in patients who had positive breath hydrogen analysis. As shown in this study, the lactose intolerance is not related to intestinal villi morphology. It is implied that primary lactase deficiency is more common in Thai people than secondary lactase deficiency.

Patients with colorectal cancer are usually treated with chemotherapy, which reduces the number of blood cells, especially white blood cells, and consequently increases the risk of infections. Some research studies have reported that aromatherapy massage affects the immune system and improves immune function by, for example, increasing the numbers of natural killer cells and peripheral blood lymphocytes. However, there has been no report of any study which provided good evidence as to whether aromatherapy with Thai massage could improve the immune system in patients with colorectal cancer. The objectives of this study were to determine whether the use of aromatherapy with light Thai massage in patients with colorectal cancer, who have received chemotherapy, can result in improvement of the cellular immunity and reduce the severity of the common symptoms of side effects. Sixty-six patients with colorectal cancer in Phichit Hospital, Thailand, were enrolled in a single-blind, randomised-controlled trial. The intervention consisted of three massage sessions with ginger and coconut oil over a 1-week period. The control group received standard supportive care only. Assessments were conducted at pre-assessment and at the end of one week of massage or standard care. Changes from pre-assessment to the end of treatment were measured in terms of white blood cells, neutrophils, lymphocytes, CD4 and CD8 cells and the CD4/CD8 ratio and also the severity of self-rated symptom scores. The main finding was that after adjusting for pre-assessment values the mean lymphocyte count at the post-assessment was significantly higher (P=0.04) in the treatment group than in the controls. The size of this difference suggested that aromatherapy with Thai massage could boost lymphocyte numbers by 11%. The secondary outcomes were that at the post assessment the symptom severity scores for fatigue, presenting symptom, pain and stress were significantly lower in the massage group than in the

An outbreak of Paederus dermatitis in Thai military personnel in 2007 was reported. Approximately ninety-one percent ofmilitary personnel who worked in a battalion located in Bangkok experienced Paederus dermatitis in April-May 2007. The most common clinical manifestations were blisters and erythematous rash. The most affected areas were head, neck, back and groin. "Kissing lesions" were seen in 17.3% of cases and 23.5% had multiple lesions. Compared with other reports, we found a high incidence of lesions in unexposed body parts. This disease should be recognized as a differential diagnosis especially in tropical countries. Awareness of the condition and its clinical features will aid early diagnosis and prompt treatment.

Quality of Life (QOL) and Health-related Quality of Life (HRQOL) are now considered as necessary outcome measures for children with cerebral palsy (CP). Various reliable and valid condition-specific HRQOL tools are available for these children. One of these is Pediatric Quality of Life Inventory (PedsQL) 3.0 CP module which has been widely used and was translated to many languages. As no Thai version is available, the authors have completed this translation. This study then aimed to investigate psychometric properties of the newly translated Thai PedsQL 3.0 CP module and to establish parent confidence in their ratings in the translated tool. Translation of the PedsQL 3.0 CP module was performed based on linguistic translation guidelines. Then, the psychometric properties of the Thai version were established. PedsQL 3.0 CP module was completed by children with CP and their parents or caregivers twice with 2-4 weeks. Respondents were 97 parents or caregivers and 54 children. Minimal missing data were found. Acceptable internal consistency was supported except for Movement and Balance Scale (self-report). Intraclass correlation coefficients for parent proxy and self-report were good to excellent (0.684-0.950). The feasibility, reliability and validity of the translated tool were supported.

Women with a history of gestational diabetes mellitus are at risk of developing prediabetes. Using a cross-sectional analytic design, the factors related to prediabetes among Thai women (n = 210) with a history of gestational diabetes mellitus were investigated. The main outcomes measured were two-hour plasma glucose after taking a 75 g oral glucose tolerance test at a six week postpartum visit. Data were analyzed using descriptive statistics and Pearson's correlation. The study showed that the incidence of prediabetes among postpartum Thai women was 26.67%. Factors associated with prediabetes were: (i) being over 35 years of age; (ii) three or more pregnancies; (iii) recurrent gestational diabetes mellitus; (iv) high plasma glucose before taking a 100 g glucose tolerance test and high postprandial plasma glucose during pregnancy; and (v) being overweight or obese at six weeks' postpartum. The results showed that nursing interventions need to be implemented to reduce plasma glucose and body mass index in order to prevent or reverse prediabetes. © 2013 Wiley Publishing Asia Pty Ltd.

Dyslipidemia is an abnormal amount of lipids and/or lipoproteins in the blood. It is a major risk factor of coronary heart disease and atherosclerosis. This study investigated two single nucleotide polymorphisms (SNPs) in the apolipoprotein E receptor 2 (ApoER2) gene in association with risk of dyslipidemia in the Thai patients. Four hundred blood samples including dyslipidemia patient (200) and unrelated normal control (200) were included in this study. Serum lipids were examined. DNAs were extracted and genotyped by using polymerase chain reaction (PCR) followed by high-resolution melting (HRM) analysis. The differences in genotype distribution between patient and normal control were assessed by Chi-square test of the SPSS software version 11.5. The data analysis revealed that two SNPs (rs3737984 and rs2297660) in ApoER2 gene had significant association with dyslipidemia. The rs3 737984 showed significant association at p-value = 0.001, in which A alleles informed the decreased risk of dyslipidemia [odds ratio and 95% CI of A allele, 0.42 (0.28-0.65)]. In contrast, the rs2297660 exhibited strongest association with an increase risk ofdyslipidemia [p-value = 0.001, odds ratio and 95% CI for theA allele was 2.38 (1.49-3.80)]. The rs2297660 may be used as biomarker for the risk of dyslipidemia in Thai ethnic.

The present study assessed the nutrition information displayed on ready-to-eat packaged foods and the nutritional quality of those food products in Thailand. In March 2015, the nutrition information panels and nutrition and health claims on ready-to-eat packaged foods were collected from the biggest store of each of the twelve major retailers, using protocols developed by the International Network for Food and Obesity/Non-communicable Diseases Research, Monitoring and Action Support (INFORMAS). The Thai Nutrient Profile Model was used to classify food products according to their nutritional quality as 'healthier' or 'less healthy'. In total, information from 7205 food products was collected across five broad food categories. Out of those products, 5707 (79·2 %), 2536 (35·2 %) and 1487 (20·6 %) carried a nutrition facts panel, a Guideline Daily Amount (GDA) label and health-related claims, respectively. Only 4691 (65·1 %) and 2484 (34·5 %) of the products that displayed the nutrition facts or a GDA label, respectively, followed the guidelines of the Thai Food and Drug Administration. In total, 4689 products (65·1 %) could be classified according to the Thai Nutrient Profile Model, of which 432 products (9·2 %) were classified as healthier. Moreover, among the 1487 products carrying health-related claims, 1219 (82·0 %) were classified as less healthy. Allowing less healthy food products to carry claims could mislead consumers and result in overconsumption of ready-to-eat food products. The findings suggest effective policies should be implemented to increase the relative availability of healthier ready-to-eat packaged foods, as well as to improve the provision of nutrition information on labels in Thailand.

This study aimed to identify proteolytic bacteria from Thai traditional fermented foods and investigate their allergenic reducing potentials to wheat and milk allergens. Nine bacteria were isolated from fermented foods as follows: fermented soybean seeds (Thua Nao), fermented soybean paste (Thua Nao), wheat flour dough of steamed stuffed bun (Sa La Pao), and soaked rice from Thai fermented rice-noodle (Kha Nhom Jeen) processing. Both phenotypic and genotypic identifications were used in this study. It was found that all isolates were Gram-positive rods. Seven isolates were matched and identified as Bacillus subtilis by both techniques, and the remaining 2 isolates were phenotypically and genotypically identified as B. licheniformis and B. subtilis, respectively. The concentrated crude enzyme of B. subtilis DB and SR could reduce allergenicity of gliadin by hydrolyzing the allergenic gliadin fragments detected by immunoblotting. Furthermore, the enzyme of B. subtilis DB could also reduce allergenicity of beta-lactoglobulin (beta-LG) detected by hydrolyzing the major allergenic epitope of beta-LG at Gln(35)-Ser(36) position. B. subtilis DB and SR can be applied for the production of hypoallergenic wheat flour or milk food products.

House dust mite is a major cause of allergic asthma and rhinitis in Thai population. Skin prick test (SPT) is a useful tool for the diagnosis of the IgE-mediated reactions. The imported commercial mite vaccine for SPT is available but it is relatively expensive. Aim of this study is to compare Siriraj Mite Allergen Vaccine (SMAV) with standardized commercial mite allergen vaccine by skin prick testing in normal Thai adults. A double blind, self-controlled study between the SMAV and standardized commercial mite allergen vaccine was performed by SPT in 17 normal Thai adult males and non-pregnant or non-lactating females aged 18-60 years. The study showed that 35.29 % of non atopic adults had positive SPT reaction to Dp and Df of both SMAV and standardized commercial mite allergen vaccine. Mean wheal and flare diameters from SPT of Dp and Df of SMAV showed strong correlation with standardized commercial mite allergen vaccine (r= 0.768 and 0.897 in Dp and Df respectively, p <0.001). The intraclass correlation was also excellent (0.893 and 0.775 in Dp and Df respectively). There was no significant difference in wheal and flare diameter between SMAV and standardized commercial mite allergen vaccine. No systemic or large local reaction was found in any of the study cases.

To investigate the genetic markers for osteoporosis bone mineral density by the genotyping of rs7041, rs4588 and rs1352845 in the DBP gene with either bone mineral density or serum 25-hydroxycholecalciferol, retinol and α-tocopherol, among 365 postmenopausal Thai women. The DBP genotypes were analyzed by a PCR restriction fragment-length polymorphism method. Serum 25-hydroxycholecalciferol was assessed using a commercial chemiluminescent immunoassay. Serum retinol and α-tocopherol were measured by reverse-phase high-performance liquid chromatography. After adjustment for age >50 years, elder Thai subjects with low BMI (≤25 kg/m(2)) and carrying the rs4588 CC genotype had a higher risk of radial bone mineral density osteoporosis (odds ratio: 6.29; p = 0.048). The rs1352845 genotype also had a statistical association with total hip bone mineral density; however, it disappeared after adjustment for age and BMI. No association was found in fat-soluble vitamins with bone mineral density. DBP genotypes may influence the osteoporosis bone mineral density in postmenopausal Thai women.

This study reviews the biological approach to Thai shopping mall’s interior design planning. The authors defined the principles of the mall’s design optimization in Thailand on the basis of the imitation of biological samples at constructive, art-compositional, organizational and ecological levels. The analysis of forming the shopping malls interiors and space-planning solutions is based on the imitation of eight basic levels of organization of living things: molecules, cells, tissues, organs, organisms, populations, ecosystem and biosphere. The examples of the direct and implicit application of biological analogues were demonstrated in the architecture and design of Thai shopping malls. In the study, the shopping mall is regarded as an open self-sufficient system with a high level of autonomy and a fortified structural organization that includes various functional components. On the basis of the analysis of existing Thai shopping malls, a list of the basic requirements for the design of the malls was compiled. This corresponds to the needs and desires of the modern customer and ensures the competitiveness of the establishment. The phenomenon of multisensory design approach that enhances the psychophysical comfort of the shopping mall visitors is described. Socio-cultural and geographical factors were identified which determine the development of biodesign in Thailand. The article reveals the potential for a combination of biology and design to enhance the aesthetics, ergonomics and efficiency of the shopping malls. The prospects within the development of this field and the possibility of applying the solutions in practice were explored.

Thai/Lanna medicinal plant recipes have been used for the treatment of several diseases including oral and cervical cancers. To investigate anti-proliferative activity on human cervical (HeLa) and oral (KB) cancer cell lines of medicinal plants selected from Thai/Lanna medicinal plant recipe database "MANOSROI III". Twenty-three methanolic plant crude extracts were tested for phytochemicals and anti-proliferative activity on HeLa and KB cell lines for 24 h by the sulforhodamine B (SRB) assay at the doses of 1 × 10(1)-1 × 10(-6 )mg/ml. The nine extracts with the concentrations giving 50% growth inhibition (GI50) lower than 100 µg/ml were further semi-purified by liquid/liquid partition in order to evaluate and enhance the anti-proliferative potency. All extracts contained steroids/triterpenoids, but not xanthones. The methanolic extracts of Gloriosa superba L. (Colchinaceae) root and Albizia chinensis (Osbeck) Merr. (Leguminosae-Mimosoideae) wood gave the highest anti-proliferative activity on HeLa and KB cell lines with the GI50 values of 0.91 (6.0- and 0.31-fold of cisplatin and doxorubicin) and 0.16 µg/ml (28.78- and 82.29-fold of cisplatin and doxorubicin), respectively. Hexane and methanol-water fractions of G. superba exhibited the highest anti-proliferative activity on HeLa and KB cell lines with the GI50 values of 0.15 (37- and 1.9-fold of cisplatin and doxorubicin) and 0.058 µg/ml (77.45- and 221.46-fold of cisplatin and doxorubicin), respectively. This study has demonstrated the potential of plants selected from MANOSROI III database especially G. superba and A. chinensis for further development as anti-oral and cervical cancer agents.

Thai heterosexual males between 20 and 39 years old are at increased risk for HIV infection. Consistent condom use is effective against HIV transmission, but little is known about determinants of consistent condom use for these males. The purpose of this study is to explore determinants of consistent condom use for this population. The determinants of interest are age, educational level, marital status, income, and concepts from the theory of planned behavior: attitude toward condom use, subjective norm about consistent condom use, perceived behavioral control (PBC) of consistent condom use, and intention to use condoms consistently. We used a cross-sectional descriptive research design with a convenience sample of 400 heterosexual Thai males between 20 and 39 years. Our sample had a mean age of 28.71 years (SD = 6.33). During the last three months, 39.5% reported using condoms consistently, 23% reported using condoms inconsistently, and 37.5% reported never using condoms. The results from the regression analyses revealed that marital status, income, subjective norm about consistent condom use, PBC of consistent condom use, and intention to use condoms consistently were determinants of consistent condom use. Also the effect of subjective norm about consistent condom use and PBC of consistent condom use on consistent condom use was mediated by intention to use condoms consistently. These results suggest that interventions to increase consistent condom use should focus on enhancing intention to use condoms consistently by promoting subjective norm about consistent condom use and PBC of consistent condom use.

To determine the risk of endometrial neoplasia in relation to endometrial thickness and to evaluate factors influencing endometrial thickness in reproductive-aged Thai women with polycystic ovary syndrome (PCOS). The present cross-sectional study was done at the Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand, between October 1, 2010, and January 31, 2013. We recruited women (aged ≥18 years) with PCOS diagnosed according to the revised 2003 Rotterdam criteria. Data were collected for physical examinations, pelvic ultrasonography, hormonal profiles, and carbohydrate metabolic profiles. Endometrial tissue was obtained using a disposable endometrial-suctioning device. The final analysis included 122 women. Six (4.9%) patients had endometrial neoplasia. All six women had an endometrial thickness of 7 mm or more, representing a risk of 8.7% (6/69) in this group. The endometrial thickness was significantly but weakly associated with body mass index (r=0.227, P=0.012), 2-hour blood glucose (r=0.323, P=0.001), fasting glucose to insulin ratio (r=0.185, P=0.042), homeostatic model assessment of insulin resistance (r=0.183, P=0.044), and free testosterone (r=0.236, P=0.009). No categorical risk factors for an endometrial thickness of 7 mm or more were identified. Thai women with PCOS and a thick endometrium (≥7 mm) had an 8.7% risk of endometrial neoplasia. Invasive endometrial surveillance for the prevention of endometrial cancer is recommended in these women. © 2018 International Federation of Gynecology and Obstetrics.

A Framework for Evaluating Economic Impacts of Rooftop PV Systems with or without Energy Storage on Thai Distribution Utilities and Ratepayers

Chaianong, A.; Bangviwat, A.; Menke, C.

2017-07-01

Driven by decreasing PV and energy storage prices, increasing electricity costs and policy supports from Thai government (self-consumption era), rooftop PV and energy storage systems are going to be deployed in the country rapidly that may disrupt existing business models structure of Thai distribution utilities due to revenue erosion and lost earnings opportunities. The retail rates that directly affect ratepayers (non-solar customers) are expected to increase. This paper focuses on a framework for evaluating impacts of PV with and without energy storage systems on Thai distribution utilities and ratepayers by using cost-benefit analysis (CBA). Prior to calculation of cost/benefit components, changes in energy sales need to be addressed. Government policies for the support of PV generation will also help in accelerating the rooftop PV installation. Benefit components include avoided costs due to transmission losses and deferring distribution capacity with appropriate PV penetration level, while cost components consist of losses in revenue, program costs, integration costs and unrecovered fixed costs. It is necessary for Thailand to compare total costs and total benefits of rooftop PV and energy storage systems in order to adopt policy supports and mitigation approaches, such as business model innovation and regulatory reform, effectively.

The pattern of infection in cervical lesions with respect to HPV subtype has not been systematically studied in Thai women. The aim here was to determine HPV prevalence, genotype, and infection pattern in cervical lesions and to estimate the potential efficacy of an HPV prophylactic vaccine. Formalin-fixed paraffin-embedded cervical tissue blocks of 410 Thai patients from 8 institutes in 4 regions of Thailand (northern, southern, north-eastern, and central) were studied. The samples included 169 low grade squamous intraepithelial lesions (LSILs), 121 high grade squamous intraepithelial lesions (HSILs), and 120 squamous cell carcinomas (SCCs). HPV-DNA was amplified by PCR using consensus primers GP5+ and GP6+. The HPV genotype was then determined by reverse linear blot assay that included 37 HPV-specific 5'-amino-linked oligonucleotide probes. Patterns of infection were classified as single infection (one HPV type), double infection (two HPV types), and multiple infection (three or more HPV types). The mean age of the subjects was 42 years. The prevalence of HPV infection was 88.8%. The highest HPV prevalence was found in the southern region (97.1%) and the lowest in the central region (78.6%). HPV-DNA was detected in 84.6% of LSILs, 90.1% of HSILs, and 93.3% of SCCs. A total of 20 HPV genotypes were identified. The five most common high risk HPV were HPV16 (83.2%), HPV18 (59.3%), HPV58 (9.3%), HPV52 (4.1%), and HPV45 (3.8%). In double and multiple infection patterns, the most common genotypes were HPV16/18 (27.8%) and HPV11/16/18 (54.9%). HPV6 was found only in LSIL and never in combination with other subtypes. HPV11 was most common in LSIL. There is no difference of HPV type distribution in women from 4 regions of Thailand with prominent HPV16 and HPV18 in all cases. The bivalent and quadrivalent vaccines have the potential to prevent 48.6 % and 74.5% of cervical cancers in Thai women. The potential of cancer prevention would rise to 87.6% if other frequent HR

2010-12-01

In this qualitative study we aimed to describe how older women in a crowded urban community perceive the food insecurity experience and deal with it. In-depth interviews were conducted among 30 Thai older women. Results revealed that older women perceived their food insecurity experience as a negative effect of the current economic downturn globally. They felt that they were confronting a crisis. Problems they dealt with included six issues. The women employed management strategies around food, health, money, and family. Our results suggest a need for welfare reform that facilitates management strategies aimed to meet food security.

1982-01-01

Eighty-three full-time stainless steel and 29 mild steel welders from one shipyard were examined clinically, and their lung function was measured. The stainless steel welders had used both tungsten inert-gas (low-fume concentration) and manual metal-arc (MMA) (high-fume concentration) welding methods. The individual exposure of the welders was estimated based on the time spent doing MMA welding, the amount of retained contaminants in the lungs (magnetopulmography), and urinary chromium excretion. The results suggest that there is a greater prevalence of small airway disease among shipyard mild steel MMA welders than among stainless steel welders. Among the stainless steel welders the impairment of lung function parameters was associated with the MMA welding method. The type of welding, then, is important when the health hazards of welders are studied, and welders cannot be regarded as a single, homogeneous group.

The threshold for heat stress on milk yield of Holstein crossbreds under climatic conditions in Thailand was investigated, and genetic effects of heat stress on milk yield were estimated. Data included 400,738 test-day milk yield records for the first 3 parities from 25,609 Thai crossbred Holsteins between 1990 and 2008. Mean test-day milk yield ranged from 12.6 kg for cows with <87.5% Holstein genetics to 14.4 kg for cows with ≥93.7% Holstein genetics. Daily temperature and humidity data from 26 provincial weather stations were used to calculate a temperature-humidity index (THI). Test-day milk yield varied little with THI for first parity except above a THI of 82 for cows with ≥93.7% Holstein genetics. For third parity, test-day milk yield started to decline after a THI of 74 for cows with ≥87.5% Holstein genetics and declined more rapidly after a THI of 82. A repeatability test-day model with parities as correlated traits was used to estimate heat stress parameters; fixed effects included herd-test month-test year and breed groups, days in milk, calving age, and parity; random effects included 2 additive genetic effects, regular and heat stress, and 2 permanent environment, regular and heat stress. The threshold for effect of heat stress on test-day milk yield was set to a THI of 80. All variance component estimates increased with parity; the largest increases were found for effects associated with heat stress. In particular, genetic variance associated with heat stress quadrupled from first to third parity, whereas permanent environmental variance only doubled. However, permanent environmental variance for heat stress was at least 10 times larger than genetic variance. Genetic correlations among parities for additive effects without heat stress considered ranged from 0.88 to 0.96. Genetic correlations among parities for additive effects of heat stress ranged from 0.08 to 0.22, and genetic correlations between effects regular and heat stress effects ranged

Seven plants in the top rank were selected from the “MANOSROI III” database using the two Thai keywords which meant impotence and sexual tonic. Boesenbergia rotunda (L.) Mansf. extract [EDP1-001(1)] gave the highest PDE inhibition activity of 4.36-fold sildenafil, a standard anti-impotence drug. Plumbago indica Linn. extract [EDP2-001(1)] exhibited the highest NO release stimulation activity of 666.85% which was 1.50-fold acetylcholine, a standard drug. Most selected plant extracts were nontoxic to EA.hy926 cells at 1.0 mg/mL. EDP1-001(1) exhibited the LD50 value of acute oral toxicity in male ICR mice of over 5,000 mg/kg body weight. EDP1-001(1) also indicated the improvement of sexual behaviors in the paroxetine-induced sexual dysfunction male mice with the evaluation of number of courtships (NC), mount frequency (MF), intromission frequency (IF), and ejaculatory frequency (EF) at 87.67 ± 6.17, 121.00 ± 23.50, 36.00 ± 3.21, and 13.67 ± 2.96 which were 2.63-, 1.27-, 0.53-, and 0.62-fold sildenafil-treated mice at day 14 of the treatments, respectively. The present study has not only confirmed the traditional use of Thai plants for the treatment of ED but also indicated the potential and application of the “MANOSROI III” database for Thai plant selection to be developed as ED food supplements.

To assess the concurrent and the construct validity of the Euro-D in older Thai persons. Eight local psychiatrists used the major depressive episode section of the Mini International Neuropsychiatric Interview to interview 150 consecutive psychiatric clinic attendees. A trained interviewer administered the Euro-D. We used receiver operating characteristic (ROC) analysis to assess the overall discriminability of the Euro-D scale and principal components factor analysis to assess its construct validity. The area under the ROC curve for the Euro-D with respect to major depressive episode was 0.78 [95% confidence interval (CI) 0.70-0.90] indicating moderately good discriminability. At a cut-point of 5/6 the sensitivity for major depressive episodes is 84.3%, specificity 58.6%, and kappa 0.37 (95% CI 0.22-0.52) indicating fair concordance. However, at the 3/4 cut-point recommended from European studies there is high sensitivity (94%) but poor specificity (34%). The principal components analysis suggested four factors. The first two factors conformed to affective suffering (depression, suicidality and tearfulness) and motivation (interest, concentration and enjoyment). Sleep and appetite constituted a separate factor, whereas pessimism loaded on its own factor. Among Thai psychiatric clinic attendees Euro-D is moderately valid for major depression. A much higher cut-point may be required than that which is usually advocated. The Thai version also shares two common factors as reported from most of previous studies.

Communicative practices in talking about death and dying in the context of Thai cancer care.

PubMed

2013-01-01

This article explores communicative practices surrounding how nurses, patients and family members engage when talking about death and dying, based on study conducted in a province in northern Thailand. Data were collected from three environments: a district hospital (nine cases), district public health centres (four cases), and in patients' homes (27 cases). Fourteen nurses, 40 patients and 24 family members gave written consent for participation. Direct observation and in-depth interviews were used for supplementary data collection, and 40 counselling sessions were recorded on video. The raw data were analysed using Conversation Analysis. The study found that Thai counselling is asymmetrical. Nurses initiated the topic of death by referring to the death of a third person--a dead patient--with the use of clues and via list-construction. As most Thai people are oriented to Buddhism, religious support is selected for discussing this sensitive topic, and nurses also use Buddhism and list-construction to help their clients confront uncertain futures. However, Buddhism is not brought into discussion on its own, but combined with other techniques such as the use of euphemisms or concern and care for others.

The mesotocinergic (MTergic) and dopaminergic (DAergic) systems have been documented to play pivotal roles in maternal behaviors in native Thai chickens. In native Thai chickens, plasma prolactin (PRL) concentrations are associated with maternal behaviors, which are also controlled by the DAergic system. However, the role of MT in conjunction with the roles of DA and PRL on the neuroendocrine regulation of the transition from incubating to rearing behavior has never been studied. Therefore, the aim of this study was to investigate the association of MT, DA, and PRL during the transition from incubating to rearing behavior in native Thai hens. Using an immunohistochemistry technique, the numbers of MT-immunoreactive (-ir) and tyrosine hydroxylase-ir (TH-ir, a DA marker) neurons were compared between incubating hens (INC; n = 6) and hens for which the incubated eggs were replaced with 3 newly hatched chicks for 3 days after 6, 10, and 14 days of incubation (REC; n = 6). Plasma PRL concentrations were determined by enzyme-linked immunosorbent assay. The results revealed that the numbers of MT-ir neurons within the nucleus supraopticus, pars ventralis (SOv), nucleus preopticus medialis (POM), and nucleus paraventricularis magnocellularis (PVN) increased in the REC hens when compared with those of the INC hens at 3 different time points (at days 9, 13, and 17). On the other hand, the number of TH-ir neurons in the nucleus intramedialis (nI) decreased in the REC13 and REC17 hens when compared with those of the INC hens. However, the number of TH-ir neurons in the nucleus mamillaris lateralis (ML) only decreased in the REC13 hens when compared with the INC13 hens. The decrease in the numbers of TH-ir neurons within the nI and ML is associated with the decrease in the levels of plasma PRL. This study suggests that the presence of either eggs or chicks is the key factor regulating the MTergic system within the SOv, POM, and PVN and the DAergic system within the

Biomaterials made from natural proteins and polysaccharides have become increasingly popular in the biomedical field due to their good biocompatibility and tunable biodegradability. However, the low miscibility of polysaccharides with proteins presents challenges in the creation of protein-polysaccharide composite materials. In this study, neat 1-allyl-3-methylimidazolium chloride (AMIMCl) ionic liquid was used to regenerate Thailand gold Bombyx mori silk and microcrystalline cellulose blended films. This solvent was found to not only effectively dissolve both natural polymers, but also preserve the structure and integrity of the polymers. A single glass transition temperature for each blend was found in DSC curves, indicating good miscibility between the Thai silk and cellulose molecules. The structural composition as well as the morphology and thermal stability of blend films were then determined using FTIR, SEM and TGA. It was found that by varying the ratio of Thai silk to cellulose, the thermal and physical properties of the material could be tuned. Blended films tended to be more thermally stable which could be due to the presence of hydrophobic-hydrophobic or electrostatic interactions between the silk and cellulose. These studies offered a new pathway to understand the tunable properties of protein-polysaccharide composite biomaterials with controllable physical and biological properties.

Understanding the cognitive attributions of smoking has the potential to advance youth smoking prevention efforts; however, research on this subject is limited in Asian countries. We attempted to determine the degree to which cognitive attributions of smoking differ among adolescents in 2 Asian countries, Thailand and South Korea. We surveyed 10th- to 12th-grade students in Chiang Mai, Thailand (N = 2516) and Seoul, South Korea (N = 1166). Logistic regression determined association of attributions and current smoking and differences in attributions between Thai and South Korean students. Items with the highest agreement among South Koreans were "helps me to deal with stress" and "helps relax" and among Thai were "feel like I am making my own decisions" and "keeps from being bored." Significant predictors of current smoking were different between samples. Only 1 cognitive attribution predicted current smoking in both samples ("helps me to deal with stress"). The pattern of relevant cognitive attributions of smoking for the 2 samples was distinct, suggesting that cross-cultural differences merit consideration when designing prevention and cessation programs. Health education should strive to dispel the use of smoking as a coping strategy for dealing with stressful situations and distressful feelings and teach adolescents alternative healthy strategies for dealing with stress. © 2012, American School Health Association.

Connections: Superplasticity, Damascus Steels, Laminated Steels, and Carbon Dating

NASA Astrophysics Data System (ADS)

Wadsworth, Jeffrey

2016-12-01

In this paper, a description is given of the connections that evolved from the initial development of a family of superplastic plain carbon steels that came to be known as Ultra-High Carbon Steels (UHCS). It was observed that their very high carbon contents were similar, if not identical, to those of Damascus steels. There followed a series of attempts to rediscover how the famous patterns found on Damascus steels blades were formed. At the same time, in order to improve the toughness at room temperature of the newly-developed UHCS, laminated composites were made of alternating layers of UHCS and mild steel (and subsequently other steels and other metals). This led to a study of ancient laminated composites, the motives for their manufacture, and the plausibility of some of the claims relating to the number of layers in the final blades. One apparently ancient laminated composite, recovered in 1837 from the great pyramid of Giza which was constructed in about 2750 B.C., stimulated a carbon dating study of ancient steels. The modern interest in "Bladesmithing" has connections back to many of these ancient weapons.

Objective: We aimed to investigate any association between a genetic polymorphism of the detoxification GSTP1 gene and risk of cervical cancer in northeastern Thailand. Materials and Methods: Genotyping of GSTP1 was performed for 198 squamous cell cervical cancer (SCCA) patients and 198 age-matched healthy controls with the PCR-RFLP method. Results: The respective frequencies of the G allele were 0.33 and 0.26 in the controls and cases, the difference being significant (OR = 0.69 [95% CI: 0.50-0.95, p=0.0192]). Among women infected with high-risk types of HPV, being a heterozygous carrier was associated with a reduced risk of cervical cancer (adjusted OR = 0.32 [95% CI: 0.12-0.91, p=0.031]). Similarly, a decreased risk was observed in heterozygous women with a non-smoking partner (adjusted OR = 0.27 [95% CI: 0.09-0.83, p=0.023]). Conclusions: GSTP1 polymorphism could influence susceptibility to cervical cancer among northeast Thai women; either as a independent factor or in combination with high-risk HPV infection. Dual-testing of HPV and the GSTP1 might prove an effective screening tool for cervical cancer. Creative Commons Attribution License

Background Fever in pregnancy is dangerous for both mother and foetus. In the 1980's malaria was the leading cause of death in pregnant women in refugee camps on the Thai-Burmese border. Artemisinin combination therapy has significantly reduced the incidence of malaria in the population. The remaining causes of fever in pregnancy are not well documented. Methodology Pregnant women attending antenatal care, where weekly screening for malaria is routine, were invited to have a comprehensive clinical and laboratory screen if they had fever. Women were admitted to hospital, treated and followed up weekly until delivery. A convalescent serum was collected on day 21. Delivery outcomes were recorded. Principal Findings Febrile episodes (n = 438) occurred in 5.0% (409/8,117) of pregnant women attending antenatal clinics from 7-Jan-2004 to 17-May-2006. The main cause was malaria in 55.5% (227/409). A cohort of 203 (49.6% of 409) women had detailed fever investigations and follow up. Arthropod-borne (malaria, rickettsial infections, and dengue) and zoonotic disease (leptospirosis) accounted for nearly half of all febrile illnesses, 47.3% (96/203). Coinfection was observed in 3.9% (8/203) of women, mostly malaria and rickettsia. Pyelonephritis, 19.7% (40/203), was also a common cause of fever. Once malaria, pyelonephritis and acute respiratory illness are excluded by microscopy and/or clinical findings, one-third of the remaining febrile infections will be caused by rickettsia or leptospirosis. Scrub and murine typhus were associated with poor pregnancy outcomes including stillbirth and low birth weight. One woman died (no positive laboratory tests). Conclusion/Significance Malaria remains the leading cause of fever in pregnancy on the Thai-Burmese border. Scrub and murine typhus were also important causes of fever associated with poor pregnancy outcomes. Febrile pregnant women on the Thai-Burmese border who do not have malaria, pyelonephritis or respiratory tract

Breast cancer is a major health problem among women around the world. Recent developments in screening and treatment have greatly improved the prognosis of patients with breast cancer in developed countries. However, in developing countries breast cancer mortality remains high.Breast cancer awareness is a first and important step in reducing breast cancer mortality. The development of a validated instrument to measure breast cancer awareness is crucial for the understanding and implementation of suitable health education programs to facilitate early deletion and minimize mortality. The objective of this study was to develop an instrument for the assessment of breast cancer awareness in Thai women. This methodological study was conducted in two stages: (1) literature searches and semi-structured interviews were conducted to generate items of the breast cancer awareness scale (B-CAS) which were subsequently examined for content and face validity, and (2) an exploration of the factor structure of the resulting instrument and an examination of its reliability. Data were collected using a self-administered questionnaire in Thai women aged 20-64 in August, 2015. A total of 219 women (response rate 97.4 %) participated in this validation study. The B-CAS contains five domains with 53 items on breast cancer awareness: 1) knowledge of risk factors, 2) knowledge of signs and symptoms, 3) attitude to breast cancer prevention, 4) barriers of breast screening, and 5) health behavior related to breast cancer awareness. Items with a content validity index <0.80 were excluded, and factor structure for the remaining items reflected the hypothesized five factor model. The scales based on all retained items was shown to have strongly internal consistency reliability (Cronbach's α=0.86). The B-CAS provides good psychometric properties to assess breast cancer awareness in women. It can be used to examine breast cancer awareness in Thai women and it could lead to the development and

2009-04-01

To test the construct validity of the Thai version of the job content questionnaire (TJCQ). The present descriptive study recruited 10415 participants from all occupations according to the International Standard Classification of Occupations. The instrument consisted of a 48-item of the job content questionnaire. Eight items newly developed by the authors from in-depth interviews were added. Exploratory factor analysis showed six factor models of work hazards, decision latitude, psychological demand, social support, physical demand, and job security. However, supervisor and co-worker support were not distinguished into two factors and some items distributed differently along the factors extracted. Confirmatory factor analysis supported the construct of six latent factors, although the overall fit was moderately acceptable. Cronbach's alpha coefficients higher than 0.7, supported the internal consistency of TJCQ scales except for job security (0.55). These findings suggest that TJCQ is valid and reliable for assessing job stress among Thai populations.

2016-01-01

Introduction Injury and psychological distress are public health priorities because of their high occurrence in the population. This study examines the longitudinal effects of injury characteristics on psychological distress. Methods Study participants were enrolled distance learning Thai adults (N = 42,785 at 2013 follow-up) residing nationwide. We analysed 2009 and 2013 data. Injury questions included injury prevalence, causes and levels of severity. Distress was measured using the standard Kessler-6. To assess the risk for post-injury distress, we used multinomial logistic regression investigating psychological distress in 2013 as an outcome including injury categories in both 2009 and 2013 as predictors, adjusted for sociodemographic factors. Results Overall injury was predictive of psychological distress. Both types of injury (traffic and non- traffic) associated with increasing psychological distress. Those that had experienced both types of injuries in the previous year had higher odds of developing psychological distress compared to those who experienced just one type. In 2013, adjusted psychological distress odds ratios were 1.46 [95% Confidence Interval 1.14–1.87] for traffic injury only; 1.26 [1.13–1.40] for non-traffic injury only; and 2.71 [2.19–3.35] for both traffic and non-traffic injuries. Increasing frequency of injury and increasing injury severity were also linked to elevated psychological distress among our Thai cohort members. Conclusions Our results revealed a significantly high risk of psychological distress following injury. With increasing occurrence of injury, especially traffic injuries in low and middle income countries such as Thailand, future policies should not only focus on physical care but also address psychological distress as an important consequence of injury.

This quasi-experimental study examined the effects of an empowerment-based nutrition promotion program on food consumption and serum lipid levels among hyperlipidemic Thai elderly. Fifty-six experimental subjects received the program; 48 control subjects maintained their habitual lifestyle. The statistical methods used were the t-test, Z-test, and chi2/Fisher's exact test. After the program, the consumption of high saturated fat, cholesterol, and simple sugar diets was significantly lower for the experimental group than for the control group. The percentage change of the serum total cholesterol of the experimental subjects was significantly higher than that of the control subjects. The number of experimental subjects that changed from hyperlipidemia to normolipidemia significantly increased compared to that for the control subjects. The implementation of this program was related to an improvement in food consumption and serum lipid levels among hyperlipidemic Thai elderly and, therefore, has implications for practice.

Lactose intolerance is common in Thai adults who ingest cow's milk but its incidence has not been clearly defined The authors evaluated 45 volunteers (15 males, 35 females), aged 21-31 yrs old, who drank one 240-ml box of milk daily. A Lactose tolerance test was performed using a breath-hydrogen test (BHT) after oral intake of 25 g of lactose dissolved in 250 ml of water The presence of gastrointestinal symptoms of lactose intolerance, flatulence, abdominal pain and diarrhea, were recorded Twenty-one subjects (47%) were categorized as lactose malabsorbers and intolerant, two subjects (4%) were malabsorbers but tolerant, and 22 of 45 (49%) were absorbers and tolerant. The incidence of lactose malabsorption was, thus, 51%; symptoms of intolerance were found in 21 of the 23 malabsorbers, making the incidence of lactose intolerance 47%. In the lactose malabsorbant and intolerant group, the more breath-hydrogen (H) the more symptoms observed All subjects who had a negative breath-H2 test had no symptoms. The breath-H2 test should be used as a standard method to evaluate lactose absorption and lactose tolerance. The incidence of lactose intolerance has decreased from the past and the symptoms are not so severe that the people limit the consumption of milk since it is a major source of food containing good quality of protein and calcium.

Medicinal plants involved in traditional Thai longevity formulations are potential sources of antimicrobial compounds. To evaluate the antimicrobial activities of some extracts from medicinal plants used in traditional Thai longevity formulations against some oral pathogens, including Streptococcus pyogenes, Streptococcus mitis, Streptococcus mutans, and Candida albicans. An extract that possessed the strongest antimicrobial activity was fractionated to isolate and identify the active compounds. Methanol and ethyl acetate extracts of 25 medicinal plants used as Thai longevity formulations were evaluated for their antimicrobial activity using disc diffusion (5 mg/disc) and broth microdilution (1.2-2500 µg/mL) methods. The ethyl acetate extract of Ficus foveolata Wall. (Moraceae) stems that exhibited the strongest antibacterial activity was fractionated to isolate the active compounds by an antibacterial assay-guided isolation process. The ethyl acetate extract of F. foveolata showed the strongest antibacterial activity with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 19.5-39.0 and 39.0-156.2 µg/mL, respectively. On the basis of an antibacterial assay-guided isolation, seven antibacterial compounds, including 2,6-dimethoxy-1,4-benzoquinone (1), syringaldehyde (2), sinapaldehyde (3), coniferaldehyde (4), 3β-hydroxystigmast-5-en-7-one (5), umbelliferone (6), and scopoletin (7), were purified. Among these isolated compounds, 2,6-dimethoxy-1,4-benzoquinone (1) exhibited the strongest antibacterial activities against S. pyogenes, S. mitis, and S. mutans with MIC values of 7.8, 7.8, and 15.6 µg/mL, and MBC values of 7.8, 7.8, and 31.2 µg/mL, respectively. In addition, this is the first report of these antibacterial compounds in the stems of F. foveolata.

BACKGROUND Stress can cause psychological and physiological changes. Many studies revealed that massage can decrease stress. However, traditional Thai massage has not been well researched in this regard. The purpose of this study was to investigate the immediate effects of traditional Thai massage (TTM) on salivary alpha-amylase levels (sAA), heart rate variability (HRV), autonomic nervous system (ANS) function, and plasma renin activity (PRA). MATERIAL AND METHODS Twenty-nine healthy participants were randomly allocated into either a traditional Thai massage (TTM) group or Control (C) group, after which they were switched to the other group with a 2-week wash-out period. Each of them was given a 10-minute mental arithmetic test to induce psychological stress before a 1-hour session of TTM or rest. RESULTS Within-groups comparison revealed that sAA was significantly decreased (p<0.05) in the TTM group but not in the C group. HRV and ANS function were significantly increased (p<0.05) and PRA was significantly decreased (p<0.05) in both groups. However, low frequency per high frequency ratio (LF/HF ratio) and ANS balance status were not changed. Only sAA was found to be significantly different between groups (p<0.05). CONCLUSIONS We conclude that both TTM and rest can reduce psychological stress, as indicated by decreased sAA levels, increased parasympathetic activity, decreased sympathetic activity, and decreased PRA. However, TTM may have a modest effect on stress reduction as indicated by a reduced sAA.

The Chinese highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) has caused a severe threat to the pig population in Southeast Asian countries. The purpose of this study was to investigate the efficacy of a type 2 PRRSV modified live vaccine (PrimePac™ PRRS, lineage 7) against a Thai HP-PRRSV (10PL01, lineage 8). Three-week-old PRRSV-free pigs were randomly assigned into three groups. Vaccinated challenged group (group 1, n = 16) was immunized with PrimePac™ PRRS vaccine at 3 weeks old. The unvaccinated challenged group (group 2, n = 16) was injected with PBS at 3 weeks old, and unvaccinated unchallenged group (group 3, n = 10) was served as a negative control. At 9 weeks old, all groups, except the negative control group, were challenged with the Thai HP-PRRSV. All pigs were monitored daily during 10 days post-infection (dpi) and were necropsied at 10 and 17 dpi. The results revealed that vaccinated challenged pigs showed significantly lower (p < 0.05) mean rectal temperatures, clinical respiratory scores, lung lesion scores, and levels of virus load in serum and lung tissue compared with the unvaccinated challenged pigs. Moreover, vaccinated challenged pigs exhibited PRRSV-specific serum neutralizing antibodies at the end of the experiment. Our findings indicated that the studied type 2 PRRSV vaccine provided partial protection against the Thai HP-PRRSV infection based on the body temperature, levels of viremia, and the severity of lung lesions. These results demonstrated that partial protection of PrimePac™ PRRS vaccine might be useful for controlling HP-PRRSV infection in the endemic area.

The fecal microbiotas were investigated in 13 healthy Thai subjects using polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE). Among the 186 DNA bands detected on the polyacrylamide gel, 37 bands were identified as representing 11 species: Bacteroides thetaiotaomicron, Bacteroides ovatus, Bacteroides uniformis, Bacteroides vulgatus, Clostridium colicanis, Eubacterium eligenes, E. rectale, Faecalibacterium prausnitzii, Megamonas funiformis, Prevotella copri, and Roseburia intestinalis, belonging mainly to the groups of Bacteroides, Prevotella, Clostridium, and F. prausnitzii. A dendrogram of the PCR-DGGE divided the subjects; vegetarians and non-vegetarians. The fecal microbiotas were also analyzed using a quantitative real-time PCR focused on Bacteroides, Bifidobacterium, Enterobacteriaceae, Clostrium coccoides-Eubacterium rectale, C. leptum, Lactobacillus, and Prevotella. The nonvegetarian and vegetarian subjects were found to have significant differences in the high abundance of the Bacteroides and Prevotella genera, respectively. No significant differences were found in the counts of Bifidabacterium, Enterobacteriaceae, C. coccoides-E. rectale group, C. leptum group, and Lactobacillus. Therefore, these findings on the microbiota of healthy Thais consuming different diets could provide helpful data for predicting the health of South East Asians with similar diets.

Bond characteristics of steel fiber and deformed reinforcing steel bar embedded in steel fiber reinforced self-compacting concrete (SFRSCC)

Steel fiber reinforced self-compacting concrete (SFRSCC) is a relatively new composite material which congregates the benefits of the self-compacting concrete (SCC) technology with the profits derived from the fiber addition to a brittle cementitious matrix. Steel fibers improve many of the properties of SCC elements including tensile strength, ductility, toughness, energy absorption capacity, fracture toughness and cracking. Although the available research regarding the influence of steel fibers on the properties of SFRSCC is limited, this paper investigates the bond characteristics between steel fiber and SCC firstly. Based on the available experimental results, the current analytical steel fiber pullout model (Dubey 1999) is modified by considering the different SCC properties and different fiber types (smooth, hooked) and inclination. In order to take into account the effect of fiber inclination in the pullout model, apparent shear strengths ( τ ( app)) and slip coefficient ( β) are incorporated to express the variation of pullout peak load and the augmentation of peak slip as the inclined angle increases. These variables are expressed as functions of the inclined angle ( ϕ). Furthurmore, steel-concrete composite floors, reinforced concrete floors supported by columns or walls and floors on an elastic foundations belong to the category of structural elements in which the conventional steel reinforcement can be partially replaced by the use of steel fibers. When discussing deformation capacity of structural elements or civil engineering structures manufactured using SFRSCC, one must be able to describe thoroughly both the behavior of the concrete matrix reinforced with steel fibers and the interaction between this composite matrix and discrete steel reinforcement of the conventional type. However, even though the knowledge on bond behavior is essential for evaluating the overall behavior of structural components containing reinforcement and steel fibers

Laughing is a kind of well known alternative medicine used to treat stressful persons or depressive patients to relax. The laughing program used in this study was initially designed by Thai psychiatrists. It consists of deep diaphragmatic breathing exercises, voice expression, facial expression exercises and aerobic exercises, which are expected to promote good health. To evaluate the effects of the laughing training on stress levels in Thai private office workers. Thirty-eight subjects whose age 25-60 years were recruited to enroll in this program. They were randomly divided into two groups: 20 people for the experimental group and 18 persons for the control group. The experimental subjects participated in laughing program for 3 days/week, 60 minutes/day for 8 consecutive weeks. The program took place from June to July 2013. The level of stress was assessed using the Suanprung stress test-60 (SPST-60). The data were analyzed by descriptive statistics, t-test dependent and t-test independent with p < 0.05 considered significant. After they joined the laughing program, no significant difference was found in the mean scores of the level of stress between the control and experimental groups. However, the sensitivities to the arousal events in the experimental group had a tendency to decrease. Laughing training may be used as a tool to promote better health. There was no significant difference in the stress levels after the program was ended except a decrement tendency in the sensitivities to the arousal events. For further study, duration and intensity of the course may be adjusted for a more effective training program.

Several pieces of evidence suggest that academic examinations fulfill the classical requirement of a psychological stressor. Academic examinations represent a stressful challenge to many students, but studies on examination-dependent corticosteroid response, a sensitive physiological indicator of a stress response, are inconsistent. In addition, several studies showed that music can decrease cortisol and adrenocorticotropic hormone (ACTH) levels, and other studies have found that music also may enhance a variety of cognitive functions, such as attention, learning, communication and memory. The present study investigated cortisol response in saliva of Thai adolescents taking academic examinations and analyzed the differences of the stress response between musician and control subjects. Also, we observed whether the academic examination-dependent corticosteroid response affected learning and memory in the test subjects, which comprised 30 musician and 30 control students, age ranging from 15 to 17 years. Mathematical examinations were used as the stressor. Pre- and post-academic examination saliva cortisol levels were measured including self-estimated stress levels. Results showed that the pre-academic examination saliva cortisol concentrations of the musician group are significantly lower than those of the control group, whereas there is no difference in the stress inventory scores. Interestingly, among students with grade point average (GPA) of >3.50, pre-academic examination cortisol levels are significantly lower in the musician compared with control group. This study suggests that under academic examination-induced stress condition, music training can reduce saliva cortisol level in Thai adolescents. Copyright © 2010 Elsevier Ireland Ltd.

Type 2 diabetes mellitus (T2DM) is increasingly prevalent in countries undergoing rapid development, including Thailand. We assessed T2DM incidence over an 8-year period in a nationwide cohort of Thai adults. Thai Cohort Study participants were surveyed in 2005, 2009 and 2013. The analysed cohort members were aged (15-88), did not have diabetes in 2005 and were followed up by questionnaire in 2013 (n=39 507). T2DM was ascertained using self-report, which has been validated using physician interviews. We calculated the 8-year cumulative incidence of T2DM. Multivariable logistic regression assessed associations between potential risk factors and T2DM incidence. 8-year cumulative incidence of T2DM (2005 to 2013) was 177 per 10 000 (95% CI 164 to 190). Crude and age-standardised cumulative incidences of T2DM by sex were 249 per 10 000 (95% CI 226 to 272) and 222 per 10 000 (95% CI 219 to 225) for men; and 119 per 10 000 (95% CI 105 to 133) and 96 per 10 000 (95% CI 94 to 98) for women, respectively. T2DM increased significantly for both sexes with increasing age and body mass index (BMI) (p trend <0.001 for both). Residence in an urban area as a child associated with T2DM among men and women (OR=1.4, 95% CI 1.1 to 1.7 and OR=1.4, 95% CI 1.01 to 1.79); this was no longer statistically significant after adjusting for BMI. Among men, smoking (OR=1.7, 95% CI 1.3 to 2.2) and alcohol intake (OR=1.8, 95% CI 1.1 to 3.0) were associated with T2DM. This study found that the sociodemographic and lifestyle changes that have accompanied Thailand's economic development are associated with T2DM risk in a large cohort of Thai adults. Our findings highlight the need to address these transitions to prevent a further increase in the national incidence of T2DM, particularly among Thai men.

Body image satisfaction significantly influences self-esteem in female adolescents. Increased reports of lowered satisfaction in this population have raised concerns regarding their compromised self-esteem. This research study, therefore, sought to identify a culturally significant moderator of the association between body image satisfaction and self-esteem in Thai female adolescents. Orientation toward self-compassion, found to be particularly high in Thailand, was examined. A total of 302 Thai female undergraduates from three large public and private universities in the Bangkok metropolitan area responded to a set of questionnaires, which measured demographic information, body image satisfaction, self-compassion, and self-esteem. Data were analyzed using correlation and multiple regression analyses. Self-compassion was tested as a moderator of the relationship between body image satisfaction and self-esteem. Although its effect was relatively small, self-compassion significantly moderated the positive relationship between body image satisfaction and self-esteem. The relationship became less stringent for those with high self-compassion. The cultivation of self-compassion was recommended in female adolescents. In addition to moderating the association between body image satisfaction and self-esteem, the benefits to health and well-being of generalizing this cultivation are discussed.

The present study aimed to characterize the pharmacokinetic profile of oxytetracycline long-acting formulation (OTC-LA) in Thai swamp buffaloes, Bubalus bubalis, following single intramuscular administration at two dosages of 20 and 30 mg/kg body weight (b.w.). Blood samples were collected at assigned times up to 504 h. The plasma concentrations of OTC were measured by high-performance liquid chromatography (HPLC). The concentrations of OTC in the plasma were determined up to 264 h and 432 h after i.m. administration at doses of 20 and 30 mg/kg b.w., respectively. The C max values of OTC were 12.11 ± 1.87 μg/mL and 12.27 ± 1.92 μg/mL at doses of 20 and 30 mg/kg, respectively. The AUC last values increased in a dose-dependent fashion. The half-life values were 52.00 ± 14.26 h and 66.80 ± 10.91 h at doses of 20 and 30 mg/kg b.w, respectively. Based on the pharmacokinetic data and PK-PD index (T > MIC), i.m. administration of OTC at a dose of 30 mg/kg b.w once per week might be appropriate for the treatment of susceptible bacterial infection in Thai swamp buffaloes. © 2016 John Wiley & Sons Ltd.

Imposex, specifically caused by TBT pollution, refers to the superimposition of male sexual characteristics in gastropod females. Seasonal variation of imposex intensity in Thais clavigera from both slightly and severely contaminated sites in Hong Kong waters was studied from 1988 to 1999. The male penis length showed significant difference between both sites and seasons. It was shortest during late autumn and early winter (October to December) and longest during spring and early summer (February to June). Female penis length also showed significant difference between sites. It did not change seasonally, however. The RPS (Relative Penis Size) index was the highest during autumn and early winter, and the lowest during spring and early summer. The VDS (Vas Deferens Sequence) index remained stable throughout the sampling period. This study showed that VDS index is a better indicator when we compare relative intensity of imposex. The comparison can only be meaningful provided the samples from different locations are taken during the same season.

Women with breast cancer receive different forms of treatment. Although treatment can save the lives of women, they can result in adverse physical, psychological, and social effects that can impact the women's quality of life. The objective of this study was to describe the experiences of breast cancer treatment among Thai women in southern Thailand. This study used qualitative methods (in-depth interviewing and drawings) with 20 Thai women who had been diagnosed with breast cancer. Data were analyzed using thematic analysis methods. Three themes emerged: (a) being a breast cancer patient: visible signs and adverse effects of therapy, (b) experiencing emotional chaos, and (c) experiencing social dysfunction. The women had to deal with physical body changes, emotional burden, treatment-related social stigma, and being marginalized within their own social context. Women experienced changes including social stigma after receiving breast cancer treatments. They had to manage stigma and difficulties themselves without sufficient professional support. It is important for nurses to understand such experiences so that they may support appropriate coping strategies suited to each woman. Community health nurses need to view each woman with breast cancer as a unique person and appreciate how to provide appropriate care and support based on each woman's experience with her illness and treatment.

The efficacy of arsenic trioxide (ATO) against acute promyelocytic leukemia (APL) and relapsed APL has been well documented. ATO may cause DNA damage by generating reactive oxygen intermediates. Suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, modulates gene and protein expression via histone-dependent or -independent pathways that may result in chromatin decondensation, cell cycle arrest, differentiation, and apoptosis. We investigated whether ATO and SAHA act synergistically to enhance the death of cancer cells. Our current findings showed that combined treatment with ATO and SAHA resulted in enhanced suppression of non-small-cell lung carcinoma in vitro in H1299 cells and in vivomore » in a xenograft mouse model. Flow cytometric analysis of annexin V+ cells showed that apoptotic cell death was significantly enhanced after combined treatment with ATO and SAHA. At the doses used, ATO did not interfere with cell cycle progression, but SAHA induced p21 expression and led to G1 arrest. A Comet assay demonstrated that ATO, but not SAHA, induced DNA strand breaks in H1299 cells; however, co-treatment with SAHA significantly increased ATO-induced DNA damage. Moreover, SAHA enhanced acetylation of histone H3 and sensitized genomic DNA to DNase I digestion. Our results suggest that SAHA may cause chromatin relaxation and increase cellular susceptibility to ATO-induced DNA damage. Combined administration of SAHA and ATO may be an effective approach to the treatment of lung cancer. -- Highlights: Black-Right-Pointing-Pointer ATO and SAHA are therapeutic agents with different action modes. Black-Right-Pointing-Pointer Combination of ATO and SAHA synergistically inhibits tumor cell growth. Black-Right-Pointing-Pointer SAHA loosens chromatin structure resulting in increased sensitivity to DNase I. Black-Right-Pointing-Pointer ATO-induced DNA damage and apoptosis are enhanced by co-treatment with SAHA.« less

Antiretroviral drug hypersensitivity in HIV patients is common. Publications have shown that Abacavir (ABC) patch testing is useful in confirming ABC hypersensitivity in 24-50% of cases with a 100% sensitivity of HLA-B*5701 in patch test positive cases. However, Nevirapine (NVP) patch testing has not been reported. (1) To evaluate the usefulness and safety of NVP patch testing in Thai HIV patients with NVP hypersensitivity. (2) To assess the correlation of positive patch tests with HLA-B*3505. Patients were classified into two groups: (1) study group of 20 HIV NVP hypersensitivity patients and (2) control group of 15 volunteers without NVP hypersensitivity. Both groups were patch tested with purified and commercialized form of NVP in various vehicles. Two HIV patients with NVP hypersensitivity were patch test positive. All controls tested negative. Three HIV patients were positive for HLA-B*3505 and the two patients with positive patch testing were both HLA-B*3505 positive. NVP patch testing in Thai HIV patients is safe and can be used to help confirm the association between NVP and hypersensitivity skin reactions. NVP patch test results significantly correlated with HLA-B*3505. The sensitivity of HLA-B*3505 for positive patch test was 100%. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Although medicinal herbs with fungicidal effects have been ubiquitously employed in traditional medicine, such effects of culinary herbs and spices still have to be elucidated. Therefore, it is noteworthy to determine the antifungal efficacy of some edible herbs used in Thai cuisine against sessile Candida albicans cultures, and to inquire if they can be further utilized as naturally-derived antifungals. Fourteen essential oils extracted from Thai culinary herbs and spices were tested for their antifungal activity against C. albicans using the agar disk diffusion method followed by broth micro-dilution method for the determination of minimum inhibitory concentration (MIC) and minimum fungicidal concentration. The oils with potent antifungal effects against planktonic fungi were then assessed for their effect against sessile fungus (adherent organisms and established biofilm culture). MIC of the oils against sessile C. albicans was evaluated by 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide reduction assay. All selected culinary herbs and spices, except galangal, garlic, and turmeric, exhibited inhibitory effects on planktonic yeast cells. Cinnamon bark and sweet basil leaf essential oils exhibited potent fungicidal effect on planktonic and sessile fungus. Sessile MICs were 8-16 times higher than planktonic MICs. Consequently, both cinnamon bark and sweet basil leaf herbal oils seem to be highly effective anti-Candida choices. (J Oral Sci 58, 365-371, 2016).

Mansf.), pine (Pinus pinaster), rosewood (Aniba rosaedora), Siam benzoin (Styrax tonkinensis), Thai moringa (Moringa oleifera), and ylang ylang (Cananga odorata) were tested for Aspergillus parasiticus and Aspergillus flavus in potato dextrose broth. Aflatoxin B 1 (AFB 1 ) was extracted from culture using a QuEChERS-based extraction procedure and analyzed with high performance liquid chromatography (HPLC) coupled to a fluorescence detector. EO of pine showed the greatest inhibition of growth and AFB 1 production of A. parasiticus, followed by EOs of rosewood, finger root, Siam benzoin, and ylang ylang. EO of finger root gave the best inhibitory effects on A. flavus, followed by EOs of rosewood, pine, ylang ylang, and Siam benzoin. EO of Thai moringa did not show any significant inhibition of aflatoxigenic fungi. The antiaflatoxigenic activities of EOs correlated with their antifungal activities in the dosedependent manner. Comparison of the application of the five selected EOs in peanut pods by direct and vapor exposure indicated that the AFB 1 production inhibitory effects of the five EOs by direct exposure were faster and more effective than by vapor exposure. EO of finger root showed the best inhibition of AFB 1 production of A. flavus in peanut pods by direct exposure, followed by EOs of pine, rosewood, ylang ylang, and Siam benzoin.

Steel production accounts for 25% of industrial carbon emissions. Long-term forecasts of steel demand and scrap supply are needed to develop strategies for how the steel industry could respond to industrialization and urbanization in the developing world while simultaneously reducing its environmental impact, and in particular, its carbon footprint. We developed a dynamic stock model to estimate future final demand for steel and the available scrap for 10 world regions. Based on evidence from developed countries, we assumed that per capita in-use stocks will saturate eventually. We determined the response of the entire steel cycle to stock saturation, in particular the future split between primary and secondary steel production. During the 21st century, steel demand may peak in the developed world, China, the Middle East, Latin America, and India. As China completes its industrialization, global primary steel production may peak between 2020 and 2030 and decline thereafter. We developed a capacity model to show how extensive trade of finished steel could prolong the lifetime of the Chinese steelmaking assets. Secondary steel production will more than double by 2050, and it may surpass primary production between 2050 and 2060: the late 21st century can become the steel scrap age.

As part of the Broader Impacts of the Cascadia Initiative, a seismic study of the Cascadia margin, and the Magnetotelluric Observations of Cascadia using a Huge Array (MOCHA) collaboration we have developed school- and museum/library-based networks of TC-1 educational seismometers. The TC-1 is constructed such that its 'guts' are visible through an transparent acrylic outer cylinder, thus it is an excellent demonstration of how fundamental physics constructs can be leveraged to design and operate a vertical-channel seismometer capable of recording signals from large earthquakes world-wide. TC-1 (aka 'slinky seismometer') networks therefore serve as the application for projects-based learning (PBL) physics and data science instruction in Oregon and Thai classrooms. The TC-1 acts as a simple harmonic oscillator, employing electromagnetic induction of a moving magnet within a wire coil. Movement of the lower magnet within an electrically conductive pipe dampens motion such that P-, S- and Surface wave phases can be identified. Further, jAmaSeis software can be configured to simultaneously show live signals from three TC-1s and has tools necessary to pick phases for earthquake signals and, thus, locate earthquake epicenters. Leveraging a long-standing collaboration between the Royal Thai Distance Learning Foundation and the University of Oregon, we developed five, 2-hour, two-way teacher professional development sessions that were transmitted live to Thai K-12 teachers and others starting mid-August, 2015. As an example, one session emphasized hands-on activities to analyze the effect of spring stiffness, inertial mass and initial displacement on the resonance frequency of a simple oscillator. Another pedagogical goal was to elucidate how math is important to understanding the analysis of seismic data, for example, how cross-correlation is useful for distinguishing between genuine earthquake signals and, say, a truck rolling by a TC-1 station.

Muay Thai fighters strongly rely on the use of the roundhouse kick due to its effectiveness (i.e. power) and implications on the final score. Therefore, different striking tempos at full power are used during training as a method to enhance kicking power. However, the neuromuscular responses are unknown. Thus, the goal of this study was to investigate neuromuscular responses to a single bout of shorter (every second = H1) and longer (every 3s = H3) kick striking time intervals, measured with the countermovement jump (CMJ). Nine professional Muay Thai fighters participated in this randomized, cross-over trial. CMJs were measured on force plates before and after (post 0min, post 5min, post 10min, post 20min and post 30min) two striking (1set x 20reps) conditions (H1; H3). Although no difference was observed between H1 and H3 values, neuromuscular fatigue parameters displayed different patterns over time. CMJ height decreased immediately after H3 striking (P<0.05), whereas for H1 condition CMJ height decreased from post20 as compared to baseline (P<0.05). Peak force in H3 condition was significantly lower at post10, post20 and post30 as compared to baseline. For H1, peak force values were lower than baseline only at post30. Peak power was significantly lower than baseline for both middle kick procedures. A slight but significant increase was observed at post5 for H3 condition, but decreased further post10 and remained constant during subsequent tests. In contrast, for H1 condition peak power remained unaffected after post10, whereas it decreased post20 and post30 minutes only when compared to post0. Results showed that both kick striking modes provoke comparable neuromuscular fatigue but H3 condition showed the potential to induce post activation potentiation. Muay Thai and conditioning coaches should focus on hard striking with both long and slow pacing during specific heavy bag or pad work.

In Thailand, artemisinin-based combination therapy (ACT) has been used to treat uncomplicated falciparum malaria since 1995. Unfortunately, artemisinin resistance has been reported from Thailand and other Southeast Asian countries since 2003. Malarone ® , a combination of atovaquone-proguanil (ATQ-PG), has been used to cease artemisinin pressure in some areas along Thai-Cambodia border, as part of an artemisinin resistance containment project since 2009. This study aimed to determine genotypes and phenotypes of Plasmodium falciparum isolates collected from the Thai-Cambodia border after the artemisinin resistance containment project compared with those collected before. One hundred and nine of P. falciparum isolates collected from Thai-Cambodia border from Chanthaburi and Trat provinces during 1988-2016 were used in this study. Of these, 58 isolates were collected after the containment. These parasite isolates were characterized for in vitro antimalarial sensitivities including chloroquine (CQ), quinine (QN), mefloquine (MQ), piperaquine (PPQ), artesunate (AS), dihydroartemisinin (DHA), ATQ and PG and genetic markers for drug resistance including the Kelch13 (k13), Plasmodium falciparum chloroquine resistance transporter (pfcrt), P. falciparum multidrug resistance 1 (pfmdr1) and cytochrome b (cytb) genes. Mean CQ, QN, MQ, PPQ and AS IC 50 s of the parasite isolates collected from 2009 to 2016 exhibited significantly higher than those of parasites collected before 2009. Approximately 57% exhibited in vitro MQ resistance. Approximately 94% of the isolates collected from 2009 to 2016 contained the pfmdr1 184F allele. Mutations of the k13 gene were detected in approximately 90% of the parasites collected from 2009 to 2016 which were significantly higher than the parasite isolates collected before. No ATQ-resistant genotype and phenotype of P. falciparum were found among the isolates collected after the containment project. Although the containment project had been

Data from ethnically diverse north-western Thailand with recent migrants from Myanmar (Burma) and China allow testing of hypotheses concerning between- and within-community differences in predominantly Yunnanese Chinese, Hmong and Lahu ethnic minority villages versus ethnic majority Thai villages. Topics include knowledge of HIV transmission, prevention and treatment, avoidance of people infected with HIV and constraints to use of health services. Respondents include women with one or more children under age five and their husbands/partners. Ethnicity is consistently associated with socioeconomic characteristics, knowledge of HIV transmission, prevention and treatment, avoidance of people living with HIV and AIDS, and constraints to use of services. Chinese community residents had the lowest levels of knowledge of HIV, especially with regard to mother-to-child transmission, the most intent to avoid contact with people living with HIV and AIDS, and the highest levels of constraints to using services, including ineligibility for government healthcare and limited Thai language ability. Associations of counselling with Thai language ability, and more knowledge and less avoidance of people living with HIV and AIDS, suggest that language-appropriate health education may help overcome disparities.

Exploring and understanding the live experiences of women smokers as well as the conditions and the family/social context of Thai society. A phenomenological approach was used and conducted from July 2011 to April 2012. The informants were 25 Thai women smokers in Bangkok and peripheral areas. Data were collected from focus group discussions and indepth interviews and was analyzed using Diekelmann and Love thematic analysis. The informants ranged in age from 14 to 66 years. The highest education level was a Vocational Certificate and the lowest level was a primary education (Grade 4). The youngest began smoking at 12 years. The average duration of smoking behavior was 22.3 years; the longest of smoking duration was 52 years. They smoked 2.4 packs of cigarettes per day on average, 6 packs per day at the maximum. Within a family setting, the highest number of people smoking and living in the same household was 13 persons. Five themes were identified as follows: 1) the starting point of smoking:-the family environment triggers smoking; 2) the meaning of smoking:-smoking means 'cigarettes are like friends ', 3) femininity and smoking.:-smoking is an individual right and is not illegal; 4) smoking and health:-smoking-health linkage is not an immediate issue as the informants did not suffer from any serious illness; and 5) view on/intention to stop smoking:-the permanent cessation of smoking was not possible due to the current environment in which their friends or family members still smoked, and because some also chose to reduce their stress by smoking. Family environment and peer group influenced the informants smoking behavior Children see their grandmother mother or elder sister smoke, so smoking is perceived as normal behavior among women as well. Most of them had chosen cigarette smoking as a way to relieve themselves from stressful environments.

To develop reliable and convenient methods for Miltenberger (Mi(a) ) blood group typing. To apply real-time polymerase chain reaction (qPCR) melting curve analysis to Mi(a) blood group typing. The Mi(a) blood group is the collective set of glycophorin hybrids in the MNS blood group system. Mi(a+) blood is common among East Asians and is also found in the Thai population. Incompatible Mi(a) blood transfusions pose the risk of life-threatening haemolysis; therefore, Mi(a) blood group typing is necessary in ethnicities where the Mi(a) blood group is prevalent. One hundred and forty-three blood samples from Thai blood donors were used in the study. The samples included 50 Mi(a+) samples and 93 Mi(a-) samples, which were defined by serology. The samples were typed by Mi(a) typing qPCR, and 50 Mi(a+) samples were sequenced to identify the Mi(a) subtypes. Mi(a) subtyping qPCR was performed to define GP.Mur. Both Mi(a) typing and Mi(a) subtyping were tested on a conventional PCR platform. The results of Mi(a) typing qPCR were all concordant with serology. Sequencing of the 50 Mi(a+) samples revealed 47 GP.Mur samples and 3 GP.Hop or Bun samples. Mi(a) subtyping qPCR was the supplementary test used to further define GP.Mur from other Mi(a) subtypes. Both Mi(a) typing and Mi(a) subtyping performed well using a conventional PCR platform. Mi(a) typing qPCR correctly identified Mi(a) blood groups in a Thai population with the feasibility of Mi(a) subtype discrimination, and Mi(a) subtyping qPCR was able to further define GP.Mur from other Mi(a) subtypes. © 2015 British Blood Transfusion Society.

Obesity is considered to be a risk of metabolic syndrome; however, data on the prevalence of metabolic syndrome in Thai obese children are scarce. The present study aims to determine the prevalence of metabolic syndrome in Thai obese children. A cross-sectional study was conducted on 113 obese children who were students of a public elementary school in Ongkharak district, Thailand, in 2013. Anthropometric data, blood pressure and biochemical parameters were measured. Metabolic syndrome was defined using modified 'the National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATPIII)' criteria. The prevalence of metabolic syndrome in obese children was 50.4%. Children with metabolic syndrome had significantly higher waist circumference (86.9 vs. 82.4 cm, p-value = 0.049), biceps skinfold thickness (17.2 vs. 14.9 mm, p-value = 0.017), suprailiac skinfold thickness (36.5 vs. 31.8 mm, p-value = 0.019), systolic blood pressure (119.7 vs. 112.6 mmHg, p-value = 0.007), diastolic blood pressure (73.7 vs. 69.0 mmHg, p-value = 0.022), fasting blood glucose (97.4 vs. 93.6 mg/dL, p-value = 0.009) and triglyceride levels (140.0 vs. 85.6 mg/dL, p-value < 0.001) than those without metabolic syndrome. HDL-cholesterol was significantly lower in children with metabolic syndrome than those in without metabolic syndrome (48.7 vs. 63.1 mg/dL, p-value < 0.001). Of the sample, approximately half of children with obesity had metabolic syndrome. The prevalence of metabolic syndrome appears to be on the increase. Strategies for childhood obesity and metabolic syndrome prevention are urgently needed for Thai children.

Thermomechanical processing of microalloyed powder forged steels and a cast vanadium steel

Dogan, B.; Davies, T. J.

1985-09-01

The effects of controlled rolling on transformation behavior of two powder forged (P/F) microalloyed vanadium steels and a cast microalloyed vanadium steel were investigated. Rolling was carried out in the austenitic range below the recrystallization temperature. Equiaxed grain structures were produced in specimens subjected to different reductions and different cooling rates. The ferrite grain size decreased with increasing deformation and cooling rate. Ferrite nucleated on second phase particles, deformation bands, and on elongated prior austenite grain boundaries; consequently a high fractional ferrite refinement was achieved. Deformation raised the ferrite transformation start temperature while the time to transformation from the roll finish temperature decreased. Cooling rates in the cast steel were higher than in P/F steels for all four cooling media used, and the transformation start temperatures of cast steels were lower than that of P/F steel. Intragranular ferrite nucleation, which played a vital role in grain refinement, increased with cooling rate. Fully bainitic microstructures were formed at higher cooling rates in the cast steel. In the P/F steels inclusions and incompletely closed pores served as sites for ferrite nucleation, often forming a ‘secondary’ ferrite. The rolling schedule reduced the size of large pores and particle surface inclusions and removed interconnected porosity in the P/F steels.

An increasing number of industrial applications need superstrength steels. It is known that refined grains and nanoscale precipitates can increase strength. The hardest martensitic steel reported to date is C0.8 steel, whose nanohardness can reach 11.9 GPa through incremental interstitial solid solution strengthening. Here we report a nanograined (NG) steel dispersed with nanoscale precipitates which has an extraordinarily high hardness of 19.1 GPa. The NG steel (shock-compressed Armox 500T steel) was obtained under these conditions: high strain rate of 1.2 μs−1, high temperature rise rate of 600 Kμs−1 and high pressure of 17 GPa. The mean grain size achieved was 39 nm and reinforcing precipitates were indexed in the NG steel. The strength of the NG steel is expected to be ~3950 MPa. The discovery of the NG steel offers a general pathway for designing new advanced steel materials with exceptional hardness and excellent strength. PMID:27892460

This study explored effects of family, school, and marketing communications on alcohol use and intention to drink of Thai students. We conducted a survey in which 5,184 students participated. Respondents were selected randomly from school districts throughout Thailand. In this survey we measured the exposure to, reception of, and perceptions concerning alcohol marketing communication, school absenteeism and achievement, family alcohol use, students' alcohol use, and drinking intentions. Findings indicated students' low alcohol use, moderate intention to drink, and high prevalence of family drinking. The levels of exposure and also the information receptivity to alcohol media marketing of Thai students were low. The respondents had a high level of media literacy on alcohol marketing communication. Multiple regression and focus group discussions provided support for the contention that there were significant effects of school achievement, absenteeism and media marketing communication on alcohol use (R2 = 14%) and intention to drink (R2 = 11%). Therefore, consideration of relevant school and alcohol policies, including monitoring of media marketing communication, will be needed.

Melasma is an acquired hyperpigmentary disorder commonly seen in Orientals. Recently it has been demonstrated that tretinoin (all-trans-retinoic acid) can produce significant clinical improvement of melasma. However, moderate cutaneous side effects (retinoid dermatitis) occurred in a number of patients. To investigate the efficacy of topical 0.05 per cent isotretinoin gel (Isotrex) in the treatment of melasma in Thai patients. Thirty patients with moderate to severe melasma entered a 40-week, randomized, vehicle-controlled clinical trial in which they applied either 0.05 per cent isotretinoin gel, or its vehicle base together with a broad spectrum sunscreen (SPF 28) daily to the entire face. They were evaluated clinically (using Melasma Area and Severity Index), and colorimetrically (using our Melasma Area and Melanin Index). After 40 weeks, the average MASI and MAMI scores of the isotretinoin-treated group decreased by 68.2 per cent and 47 per cent respectively, while the corresponding control scores declined 60 per cent and 34 per cent. There was no statistically significant difference between the isotretinoin and vehicle groups. When the MASI and MAMI scores of each visit were compared to their baseline data, a statistically significant reduction of the score was first noted at weeks 4 and 12 respectively. Lightening of melasma, as determined clinically (MASI score), correlated well with pigmentation measurements (MAMI score). Side effects were limited to a mild transient "retinoid dermatitis" occurring in 27 per cent of isotretinoin-treated patients. Daily use of broad spectrum sunscreen has a significant lightening effect on melasma in Thai patients. However, there was no statistically significant difference between the isotretinoin and vehicle-treated group.

The Thai/Lanna medicinal plant recipe database "MANOSROI II" contained the medicinal plant recipes of all regions in Thailand for the treatment of various diseases including anti-cancer medicinal plant recipes. To investigate anti-proliferative activity on HeLa cell lines of medicinal plant recipes selected from the Thai/Lanna medicinal plant recipe database "MANOSROI II". The forty aqueous extracts of Thai/Lanna medicinal plant recipes selected from the Thai/Lanna medicinal plant recipe database "MANOSROI II" were investigated for anti-proliferative activity on HeLa cell line by SRB assay. The apoptosis induction by caspase-3 activity and MMP-2 inhibition activity by zymography on HeLa cell line of the three selected aqueous extracts, which gave the highest anti-proliferative activity were determined. Phytochemicals and anti-oxidative activities including free radical scavenging activity, inhibition of lipid peroxidation and metal chelating inhibition activities were also investigated. Sixty percentages of the medicinal plant recipes selected from "MANOSROI II" database showed anti-proliferative activity on HeLa cell line. The recipes of N031(Albizia chinensis (Osbeck) Merr, Cassia fistula L., and Dargea volubilis Benth.ex Hook. etc.), N039 (Nymphoides indica L., Peltophorum pterocarpum (DC.), and Polyalthia debilis Finet et Gagnep etc.) and N040 (Nymphoides indica L. Kuntze, Sida rhombifolia L., and Xylinbaria minutiflora Pierre. etc.) gave higher anti-proliferative activity than the standard anti-cancer drug, cisplatin of 1.25, 1.29 and 30.18 times, respectively. The positive relationship between the anti-proliferative activity and the MMP-2 inhibition activity and metal chelating inhibition activity was observed, but no relationship between the anti-proliferative activity and apoptosis induction, free radical scavenging activity and lipid peroxidation inhibition activity. Phytochemicals found in these extracts were alkaloids, flavonoids, tannins and xanthones

The naturally occurring radioactive materials (NORMs) distributed in products, by-products and waste produced from Thai mineral industries were investigated. Samples were analysed for radioactivity concentrations of two principal NORM isotopes: (226)Ra and (228)Ra. The enrichment of NORM was found to occur during the treatment process of some minerals. The highest activity of (226)Ra (7 × 10(7) Bq kg(-1)) was in the scale from tantalum processing. The radium concentration in the discarded by-product material from metal ore dressing was also enriched by 3-10 times. Phosphogypsum, a waste produced from the production of phosphate fertilisers, contained 700 times the level of (226)Ra concentration found in phosphate ore. Hence, these residues were also sources of exposure to workers and the public, which needed to be controlled.

The composite material of 304 stainless steel reinforced Q235 carbon steel has been prepared by modified hot-rolling process. The resulted material was characterized by scanning electron microscope, three-electrode method, fault current impact method, electrochemical potentiodynamic polarization curve measurement and electrochemical impedance spectroscopy. The results showed that metallurgical bond between the stainless steel layer and carbon steel substrate has been formed. The composite material exhibited good electrical conductivity and thermal stability. The average grounding resistance of the composite material was about 13/20 of dip galvanized steel. There has no surface crack and bubbling formed after fault current impact. The composite material led to a significant decrease in the corrosion current density in soil solution, compared with that of hot dip galvanized steel and bare carbon steel. On the basis polarization curve and EIS analyses, it can be concluded that the composite material showed improved anti-corrosion property than hot-dip galvanized steel.

The CFD code CFX4.4 was used to simulate an experiment in the ThAI facility, which was designed for investigation of thermal-hydraulic processes during a severe accident inside a Light Water Reactor containment. In the considered experiment, air was initially present in the vessel, and helium and steam were injected during different phases of the experiment at various mass flow rates and at different locations. The main purpose of the proposed work was to assess the capabilities of the CFD code to reproduce the atmosphere structure with a three-dimensional model, coupled with condensation models proposed by the authors. A three-dimensional modelmore » of the ThAI vessel for the CFX4.4 code was developed. The flow in the simulation domain was modeled as single-phase. Steam condensation on vessel walls was modeled as a sink of mass and energy using a correlation that was originally developed for an integral approach. A simple model of bulk phase change was also included. Calculated time-dependent variables together with temperature and volume fraction distributions at the end of different experiment phases are compared to experimental results. (authors)« less

The metabolic syndrome is related to increased risk of developing cardiovascular disease and type 2 diabetes. Adiponectin is an adipocyte-secreted protein with insulin-sensitizing and anti-atherogenic properties. The aims of this study were to evaluate adiponectin levels and biochemical parameters in metabolic-syndrome subjects and healthy controls. The study also sought to identify links between two polymorphisms, -11377C>G (rs266729) and +45T>G (rs2241766) of the adiponectin gene, in relation to adiponectin levels and the metabolic syndrome. Three hundres and thirty-two Thai volunteers: 164 metabolic-syndrome subjects and 168 healthy control subjects were investigated. The adiponectin and HDL-C levels of the metabolic-syndrome group were significantly lower than the control group (p<0.001). Decreased concentration of adiponectin was associated with -11377C>G polymorphism (p<0.001); this polymorphism was significantly more frequent in the metabolic syndrome group than in the control group (p<0.001). However, +45T>G polymorphism of the adiponectin gene was found not to be related to adiponectin level or metabolic syndrome. Therefore, -11377C>G polymorphism was related to the metabolic syndrome susceptibility, and this polymorphism impacted on circulating adiponectin concentrations among Thais.

The purpose of this paper is to help consolidate and understand management perceptions and experiences of a targeted group (n=7) of Vice-Presidents of international Private Thai hospitals in Bangkok regarding medical tourism impacts. The method adopted uses a small-scale qualitative inquiry. Examines the on-going development and service management factors which contribute to the establishment and strengthening of relationships between international patients and hospital medical services provision. Develops a qualitative model that attempts to conceptualize the findings from a diverse range of management views into a framework of main (8) - Hospital Management; Hospital Processes; Hospital Technology; Quality Related; Communications; Personnel; Financial; and Patients; and consequent sub-themes (22). Outcomes from small-scale qualitative inquiries cannot by design be taken outside of its topical arena. This inevitably indicates that more research of this kind needs to be carried out to understand this field more effectively. The evidence suggests that Private Thai hospital management have established views about what constitutes the impact of medical tourism on hospital policies and practices when hospital staff interact with international patients. As the private health service sector in Thailand continues to grow, future research is needed to help hospitals provide appropriate service patterns and appropriate medical products/services that meet international patient needs and aspirations. Highlights the increasing importance of the international consumer in Thailand's health industry.

Fractional radiofrequency (RF) technology is often the preferable skin resurfacing treatment, especially among Asian patients. Second generation fractional RF technology has exclusive capability to produce separate biological responses (ablation, coagulation, or a combination of both) with 3 distinguished penetration depth programs. The aim of this study was to evaluate the efficacy and safety of a fractional RF handpiece such as this, on the Thai population. Fifty-five Thai patients were treated with a fractional RF handpiece. The clinical assessment included a pain score, satisfaction survey, physician assessment, a combined patient and physician's assessment of skin condition, and clinical photographic assessments. The wound healing response was evaluated according to 5-time points: immediately after applying a pulse, post 24 hours, post 7 days, post 1 month and post 8 weeks. The obtained patient satisfaction score was "very satisfied" among 74% of the patients, post 3 sessions. Positive correlation was found between patient satisfaction and the physician's assessment. The skin condition assessment showed an increase from an average of 4.2 to 7.9. All treated symptoms improved after each treatment and the clinical outcome lasted at least up to 3-5 months. No significant adverse events were recorded. The in vivo prospective study showed a dose-related response in the deepness of the coagulation injury. In addition, there was evidence for a progressive healing process beginning shortly after exposure and completed within a week. This study clinically and histologically supports the efficacy of fractional RF handpiece in question with a high safety profile. © 2017 Wiley Periodicals, Inc.

To evaluate the prevalence of vitamin supplementation in Thai children aged 1-5 years at Queen Sirikit National Institute of Child Health (QSNICH), parental knowledge of vitamins, practices, and related factors such as nutritional status in vitamin supplementation. A cross-sectional study was performed at the Well Child Clinic, QSNICH, from 1-31 May 2005. Five hundred parents of young children, aged 1-5 years were interviewed by using the questionnaire to obtain information regarding knowledge and practices of vitamin supplementation. Weight and length/height were measured and nutritional status was assessed using the Thai growth reference. The relationships among vitamin supplement, nutritional status, and other related factors were analyzed using Chi-square test. The p-value < 0.05 was considered statistically significant. Prevalence of vitamin supplementation was 76%, including vitamin C 62%, multi-vitamin (MTV) 35%, and cod-liver oil 20%. Regarding parental knowledge of vitamins, 57% of them knew the health benefits but 74% did not know the toxic effects of vitamins. The reasons for vitamin supplementation were poor feeding 63%, under-weight 23% and unhealthy status 14%. Vitamins were obtained from over-the-counter 59%, health services 40%, and friends 1%. Vitamin supplementation was significantly higher in children over 2 years of age, whose parents knew the benefits of vitamins, and in those children with malnutrition. The prevalence of vitamin supplementation was high in malnourished children, over 2 years of age whose parents had knowledge about benefits of vitamins. Parents should be warned about the dangers of high dose of vitamin consumption.

To estimate the incidence of abnormal cervical cytology by ThinPrep Pap-tests and cervical intraepithelial neoplasia (CIN) in young adult reproductive-aged Thai women. A total of 1254 women distributed in all regions of Thailand were monitored from 2002 through 2004. Women were screened for abnormal cervical cytology using the ThinPrep method every 6 months. Interpretation of cervical cytology was based on the Bethesda system, version 2001. Women who had the ThinPrep Pap results as atypical squamous cells of undetermined significance or worse underwent colposcopic examination. The ThinPrep and all cervical tissue samples obtained from diagnostic or therapeutic procedures were analyzed and reviewed by Covance Central Laboratory Service, Inc., Indianapolis, USA. The cumulative incidence of abnormal ThinPrep Pap-tests was as follows: 15.3 per 100 woman years (WY) (95% confidence interval [CI] 12.3, 18.9) at 6 months; 12.3 per 100 WY (95% CI 10.3, 14.6) at 12 months; and 11.6 per 100 WY (95% CI 10.0, 13.5) at 18 months. Of 1448.6 woman years of follow up, the incidence of CIN1 was 4.1 per 100 WY (95% CI 3.2, 5.3); CIN2 0.8 per 100 WY (95% CI 0.4, 1.4); and CIN3 0.6 per 100 WY (95% CI 0.3, 1.2). The incidence of abnormal ThinPrep Pap-test and CIN in young adult Thai women had been reported. No comparable data is available.

Vasectomy and vasectomy reversal the Thai way.

In 1972 the ratio of female sterilization acceptors to vasectomy acceptors in Thailand was 24.5:1; in 1978 the ratio was 2.8:1. Several factors are responsible for this change. First, a national family planning program to support voluntary family planning started in 1970 and lowered the population growth rate from 3.2% in 1973 to 2.1% in 1982. Second, the desired family size in Thailand is 3 and it is generally agreed that the solution is voluntary sterilization as a more cost effective fertility control method. Thirdly, misunderstandings about vasectomy were cleared up through media campaigns which cleared the way for greater acceptance. Fourth, in 1975 special clinics at big hospitals and a mobile unit were set up to perform vasectomies. Lastly, a group of nongovernment organizations has been set up, such as the Thai Association for Voluntary Sterilization, to provide the infrastructure for vasectomy campaigns. Requests for vasectomy reversals have, expectedly, increased as well, usually caused by marriage, child's death, improved finances, and psychosexual health. In a recent study of 32 cases, positive sperm reappearance after vas reanastomosis was found in 71.4% and the pregnancy rate was 52.3%.

Fasting in Ramadan has adverse effects on health of Muslims with diabetes. Key strategies to prepare the patients are to provide appropriate health education to the patients prior to Ramadan and to adjust anti-diabetic medicines during Ramadan. To study outcomes of the specific health care services that providing health education in parallel with counseling by Islamic leader The Thai Muslims with type 2 diabetes mellitus were divided into two groups. There were 62patients in experimental group that was provided with specific health care service for Thai Muslims with diabetes in which health education prior to Ramadan and adjustment ofanti-diabetic medicine applied. The other was control group with 28patients that was provided only with original health care service. The results were monitored after Ramadan by interviews, weight and waist measurements, blood pressure measurement and blood tests. Both mean systolic and diastolic blood pressure were well controlled in both groups and slightly decreased after Ramnadan. The mean diastolic blood pressure of the experimental group decreased after Ramadan (p-value = 0.041). From behavior point of view, it was found that the patients in the experimental group had consumed less sweetenedfood (p-value = 0.002). There was no incidence ofsevere hypoglycemia in either experimental or control group. The number and portion of patients with hypoglycemic symptoms in experimental group were lower than those in controlled group (p-value = 0.013). Specific health care service by providing health education prior to Ramadan and adjustment ofanti-diabetic medicine application resulted in a positive effect as the patients tended to consume less sweetenedfood to keep blood sugar level in control. Fasting could affect the patients 'health in apositive way as it helps to control blood pressure, while in parallel, adjustment of anti-diabetic medicine application helps to prevent hypoglycemia. This health care service, which can be achieved in

Late Mesozoic tectonics of the Southern-Thai Peninsula: from transpression to basins opening

The petroleum basins of the Southern Thailand Peninsula are poorly known and their final geometry is controlled by the Tertiary stress variations applied on pre-existing Paleozoic and Mesozoic basement structures. From the end of Mesozoic times, the arrival of Indian plate was accomodated by transpressionnal deformation along the Western Margin of Sunda Plate. Evidences of this strain are the motions along several regional strike Slip Faults (Sagaing, Three Pagodas, Mae Ping, Red River, Ranong and Klong Marui Faults) as well as compressional features (folds and thrusts) evidenced onshore. Due to changes in the boundary forces, these structures were reactivated during the Tertiary, leading to the opening of basins in this part of Sundaland. We present a structural analysis based on geomorphology, fieldwork and seismic interpretation of the Southern Thai Peninsula with emphasis on the deformation's style onshore from Ranong to Satun and offshore from Eastern Mergui to Songhkla. By analyzing morphostructures and drainage anomalies from Digital Elevation Model (SRTM and ASTER), we highlight a predominance of N-S structures in the Southern Thai Peninsula: both in the granitic belt and in the sedimentary cover. The Triassic-Jurassic (Indosinian) post-collision granitic belt is intensely fractured, with 2 penetrative directions: N140 and N50. On both sides, the sedimentary units appear folded at a large wavelength (~20km). On most of the studied outcrops, Triassic to Early Cretaceous series are gently tilted and weakly fractured whereas the Paleozoic ones shows intense fracturation and steep dipping beds. Moreover, all the Paleozoic stratas display a constant N-S S1 which does not appear in the Mezosoic sediments. Althought most of the post-Mesozoic sediments do not crop out due to thick vegetal cover, several Tertiary basins can be easily seen from seismic data both onshore and offshore. These data suggest that rifting started in the Eocene and was accommodated by large
