Abstract: Background: Men who have sex with men (MSM) are highly vulnerable to HIV infection, but this population can be particularly difficult to reach in Thailand. This study aimed to estimate the number of MSM in Chiang Mai Thailand, in order to plan HIV control and prevention. Methods: The total of 348 potential MSM were identified at eight contact locations, including two public parks, two bars, two massage parlors and two pubs in Chiang Mai. Trained 16 research enumerators and 16 enumerators were trained to extend a recruitment of brooches to MSM. The MSMs were captured one week apart. A record was kept of when, where and by whom the invitation was extended and received, and of refusals. The total estimate of MSM was derived from capture-recapture calculation. Results: The total MSM in Chiang Mai Thailand estimated by capture and recapture method was 733 (95%CI = 480 - 948) or the estimate was 7.3% (95%CI = 7.1% - 14.1%). Conclusions: Capture and recapture method can be used to enumerate and provide accurate and reliable estimates of the MSM population in any area, provided that certain conditions are controlled. MSM who are engaged in personal community represent a sizeable population who urgently need to be targeted by HIV and STDs prevention strategies.

World Journal of AIDS (WJA) , 2017, DOI: 10.4236/wja.2017.72009
Abstract: The study was conducted to explore factors associated with condom use of young Thai men conscripts. Methods: A cross-sectional study was conducted. Participants were 159 conscripts in second year who served in the Royal Thai Army by lottery method. Demographic data, sexual history including condom use, HIV and STDs and knowledge were collected using a self-administered questionnaire. Logistic regression was used to analyze the data. Results: Condom use at the last sex was 41.18% of the conscripts aged 20 - 27 years and secondary school education completed of 74.2%. 25.78% had experience with drugs used but injection was rare (6.9%). Age at the first sex was reported lowest at 11 years, 9.4% reported first sex with men and 21.38% were married. The participants have sexual history (last six months) with female only of 83.2%, male only of 4.1% and both of 14.6%. Among these only 12.6% reported every time of condom use and 19.5% never used condom. Older age, higher education, drinking alcohol, drugs use and higher knowledge were associated with condom use with statistical significance. Conclusions: Condom use among male Thai conscripts was low. Education and a condom use program are urgently needed to prevent future spread of HIV and STDs.

BMC Medical Education , 2009, DOI: 10.1186/1472-6920-9-12
Abstract: The CAL package was developed using computer software, "Xerte" and "Flash Macromedia". The effectiveness of the CAL package was evaluated in 32 childcare students in the UK, who were randomised to watch the CAL package or to read the information leaflet containing the same information (n = 16 in each group). Retention performance, level of enjoyment, and level of confidence to identify a child with autism, after the interventions, were evaluated. The data obtained from two studied groups was analysed using unpaired Student's t-test, 95% confidence interval, and effect size.Students who watched the CAL package had superior retention performance percentage scores (p = 0.02, 95% CI = 0.83–12.19, effect size = 0.8) and level of enjoyment (p = 0.04, 95% CI = 0.03–2.75, effect size = 0.7) compared with students who read the information leaflet. However, there was no significant difference in level of confidence to identify a child with autism (p = 0.39, 95% CI = -1.80–0.72, effect size = -0.3).The CAL package developed was an effective method of educating people who work with children about autism.Autism is a common neurodevelopmental disorder in children. Clinical features of autism consist of three main impairments, known as the "triad of impairment": impairment in social interaction, impairment in communication and impairment in imagination. Recent research documented that prevalence for all autistic spectrum disorders (ASD) varied from 52 to 67 per 10,000, depending on geography and research methodology [1-4]. Although, there are many standard diagnostic instruments utilised to help to diagnose autism [5-7], the diagnosis of autism remains difficult, especially before the age of 3 [8]. Clinical manifestations are sometimes less obvious and not compatible with the diagnostic instruments. Consequently, the diagnosis of autism may be delayed and that may affect the outcome of children with autism. The early detection of autism can lead to early interventions which may we

Abstract: One hundred twenty one isolates of Bacillus thuringiensis were isolated from 91 soil samples collected in the national park and wildlife sanctuary in Krabi province. All isolates of B.thuringiensis were tested for their insecticidal activity against Spodoptera litura, S. exigua and Plutella xylostella larvae. Seven isolates of B. thuringiensis named JCPT7, JCPT16, JCPT18, JCPT64, JCPT68, JCPT74 and JCPT89 exhibited toxic activities against the insects, more than 90% mortality. The detection of cry gene of these isolates was done by a method based on polymerase chain reaction (PCR). The PCR result indicated that cry1Ab, cry1Ac, cry1C, cry1D, cry1I, cry9A, cry9B and cry2A were on chromosomal DNA and cry1Aa, cry1Ab, cry1Ac, cry1C, cry1D, cry1I and cry2A were on plasmid DNA. This study has introduced the promising B. thuringiensis isolates collected from soil samples which could be developed as an effective biocontrol agent for Lepidopterous pest.

Abstract: Introduction: There is scarce of data in terms of health-related quality of life for hip fracture patients in Thailand due to the following: (i) lack of epidemiological aspects of hip fracture (eg. the relative incidence of osteoporosis, falls fractures and repeat fractures) in particular subgroups, (ii) lack of health status and quality of life aspects of both illness itself and the availability of different treatment options especially for elderly people. (iii) a substantial variation in terms of outcomes of care for patients and service for hip fractures. Objective: Hip fracture is a major healthcare burden in Thailand. This study explores quality of life for hip fracture patients from perspective of (i) Reliability of patient-reported outcomes (ii) Some clinical and demographic characteristics related to patient-reported outcomes Method: Pre-hospital discharge 201 hip fracture patients were screened and follow-up over one year. Mail survey by a self-rated Medical Outcomes Study, a 36-item Short-Form Health Survey (Thai) dispatched for follow-up, other clinical and demographic characteristics were collected through direct interviews from patients or caregivers during recruitment with simultaneous crosschecking from medical records. A descriptive cross-sectional analysis was performed.Result: Mails responder represented by 59.2% (N=119), with 36.1% (N=43) and 63.8% (N=76) for patient and caregiver rated outcomes. Mean(SD), [95% CI] score for physical, mental and global health of patient and care-giver rated outcomes of 36.2(10.6)[32.9-39.4], 54.5(10.0)[51.4-57.5],43.9(9.3)[41.0-46.7], and 34.6(12.3)[31.7-37.4], 52.5(12.3)[49.6-55.3],42.7(11.1)[40.1-45.2] were not statistically difference with p-value at 0.630,0.330 and 0.788 respectively. Respecting Cronbach’s alpha reliability coefficient by patients versus caregivers rated of the MOS SF-36 were 0.90 vs 0.91, 0.78 vs 0.84 and 0.90 vs 0.92. The presence of comorbidity significantly explains differences for quality of life outcomes in all health dimensions. Conclusion: Health-related quality of life assessment with MOS SF-36 one year after hospital discharge for hip fractures patients was reliable. These results provided useful information related to post-treatment health-related quality of life outcomes. The shortcoming and limitation in terms of recall and report bias could be anticipated. The authors provided further justification for strength and weakness of implications for post-discharge health-related quality of life mail survey and future research aspects suggested.

Advances in Materials Science and Engineering , 2013, DOI: 10.1155/2013/918380
Abstract: Dimensional and surface quality for plate production control is facing difficult engineering challenges. One of these challenges is that plates in large-scale mass production contain geometric uneven surfaces. There is a traditional measurement method used to assess the tile plate dimensions and surface quality based on standard specifications: ISO-10545-2: 1995, EOS-3168-2: 2007, and TIS 2398-2: 2008. A proposed measurement method of the dimensions and surface quality for ceramic oblong large-scale tile plate has been developed compared to the traditional method. The strategy of new method is based on CMM straightness measurement strategy instead of the centre point in the traditional method. Expanded uncertainties budgets in the measurements of each method have been estimated in detail. The capability of accurate estimations of real actual results for centre of curvature (CC), centre of edge (CE), warpage (W), and edge crack defects parameters has been achieved according to standards. Moreover, the obtained results not only showed better accurate new method but also improved the quality of plate products significantly. 1. Introduction Advanced metrology techniques are became used in various fields of science and production engineering applications. There are two new basic approaches, the contact techniques and noncontact measuring techniques. These techniques include scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray transmittance photoelectron spectroscopy (XPS), atomic force microscopes (AFM), computed tomography (CT), laser interferometric method, and coordinate measuring machines (CMM) use in dimensional metrology [1]. Three different methods such as AFM, stylus Talysurf system, and noncontact laser system were applied for measuring the surface roughness parameters of ceramic tiles and metallic surfaces in 1996 [2]. That work concludes: the noncontact laser method produced relatively high values of the surface roughness parameters other than stylus method regardless of the measurement accuracy, because the stylus tip size and its wear play a part in the measurement. While, with the wonderful progress in material science and CNC-CMM software, it has become very easy there small tip size, high scratch resistant and reduce tip touching force which reduces the risk of damage during measurement. Recently, the coordinate dimensional metrology became the key to global quality assurance systems of industrial engineering products. CNC-CMM machine is a computer-numerical-controlled device equipped with ruby touch probe for

Abstract: In vitro transport of these three esters was observed in Caco-2 cell monolayers. The ester compounds 1, 2 and 3 at a concentration of 10 μM were hydrolyzed by porcine liver esterase.All esters transported across the Caco-2 cell without enzymatic hydrolysis. The apparent permeability coefficients Papp of compound 1 at 53 μM and 106 μM were 13.94 (0.60) × 10-6 and 14.33 (0.17) × 10-6cm/s respectively, while those of compound 2 were 9.45 (0.29) × 10-6 and 10.08 (0.32) × 10-6cm/s, respectively. Papp values of compound 3 were 7.48 (0.31) × 10-6cm/s at 53 μM and 8.60 (0.55) × 10-6cm/s at 106 μM. Papp values of the parent compound (compound D), i.e. (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-ol were 8.53 (0.83) × 10-6cm/s at 53 μM and 16.38 (0.61) × 10-6cm/s at 106 μM. The ester hydrolysis of compounds 1, 2 and 3 by porcine liver esterase was monitored by HPLC and the hydrolysis reactions were completed within 10 minutes.Using the Caco-2 cell monolayer model, the present study finds that compounds (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-yl linoleate (1), (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-yl oleate (2) and (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-yl palmitate (3) originated from Prasaplai preparation (a Thai herbal formula) may be transported through a facilitated mechanism and serve as pro-drugs to increase the compound D level in the blood.Zingiber cassumunar (Z. cassumunar, cassumunar ginger) and Nigella sativa (N. sativa, black cumin) are widely used as single herbs or as components of herbal formulae in Asian traditional medicines. One of the compounds isolated from Z. cassumunar, (E)-4-(3,4-dimethoxyphenyl)but-3-en-1-ol is named compound D [1,2]. In a carrageenan-induced rat paw edema model, compound D from a hexane extract of Z. cassumunar showed a potent inhibitory effect on edema formation [2]. Compound D also demonstrated a dose dependent uterine relaxant effect in uterus of non-pregnant rat [3].Three artificial fatty acid esters were found in the mixture of dry powders

Abstract: Background: Vitiligo or leukoderma is a chronic skin condition that causes loss of pigment due to destruction of melanocytes, resulting in irregular pale patches of skin. Vitiligo is a polygenic disease and is associated with autoimmunity with an unknown etiology. Aims: One of the candidate genes which has a strong association with several autoimmune diseases is ctla0 -4 gene located in chromosome 2q33 region. We investigated the possible association between ctla0 -4 gene polymorphism in exon 1 (A49G) and vitiligo in patients from South India and compared the distribution of this polymorphism to matched control groups. Patients and Methods: The polymorphism was detected by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method in 175 patients and 180 normal, age/ethnicity matched individuals. Consistency of genotype frequencies with the Hardy-Weinberg equilibrium was tested using a ÷2 test. Results: There was no significant difference between the genotype (P=0.93) and allele (P=0 .615) frequencies of CTLA-4 A49G polymorphism in patients and normal healthy individuals. However there was significant association of the CTLA-4 genotype ( P=0.02) and allelic frequency ( P=0.008) between the segmental and non-segmental sub groups within vitiligo. Conclusion: Our results indicate that there is no association between CTLA-4 A49G gene polymorphism and vitiligo in southern Indian population.
