title: Radiation dose to patients and medical staff during endoscopic retrograde cholangiopancreatography (ERCP) procedure

description: To evaluate the radiation dose to patient at two positions (prone and left lateral) and to medical staff during ERCP procedure using dose area product (DAP) meter and thermoluminescent dosimeter (TLD). Data were recorded on 20 patients at prone position and 20 patients at left lateral position. The radiographic-fluoroscopic system manufactured by Siemens Model Polystar was used for ERCP procedure at King Chulalongkorn Memorial Hospital. Dose Area Product (DAP) manufactured by PTW Model Diamentor E, a transmission ionization chamber was attached to X-ray collimator to record the dose-area (cGy.sq.cm) in order to determine the entrance surface air kerma (ESAK, mGy) of the patients at two positions (prone and left lateral) while the Kodak Portal Pack for localization imaging was placed on the patient's couch to determine the exposed area (sq.cm) on the surface of the patient. TLD was attached at five positions, left eye, thyroid, left forearm, lower abdomen and left leg of the medical staff during ERCP procedure. The average patient skin dose from DAP was higher at left lateral position of 124.06 (23.3-229.3) mGy than 82.93 (39.76-174.74) mGy at prone position. The medical staff received the maximum dose per procedure at the left forearm of 244.02 (54.79-1628.66) μGy for patient at left lateral position and 131.09 (29.9-382.81) μGy at prone position. The average surface dose the patient received during ERCP procedure at prone and lateral positions were 82.93 and 124.06 mGy per procedure which were significantly different. The medical staff also received higher dose at left lateral position than at prone position, but they were adequately protected from the risk of working with the radiation. The relation between medical staff and patient doses was established. The highest ratio between average medical staff doses and dose-area product is the left forearm and the lowest ratio is the lower abdomen of ERCP procedure. The highest ratio is 111.66 μGy / 10 Gy.sq.cm and the lowest ratio is 7.53 μGy / 10 Gy.sq.cm. The medical staff dose can be estimated from the patient dose using DAP method. This will help the medical staff to avoid the excess dose during their work.

title: Absorption and release characteristics of curcumin in bacterial cellulose film

description: In this research, absorption and release characteristica of curcumin in bacterial cellulose (BC) film by Acetobacter xylinum was studied using the curcumin solution at 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 (mg/ml) absorbed into the wet BC films. Then the physical properties of the developed bacterial cellulose-curcumin (BCC) films such as mechanical property and equilibrium water content and the biological properties such as antifungal ability, antibacterial ability (test by Disc diffusion) and the inhibition of B16 melanoma cells (test by MTT assay) were investigated. From the study, the mechanical properties and equilibrium water content of the BCC films were found to be relatively lower than those of the BC film. Fourier tansform infrared spectroscopy analysis illustrated the interaction between BC fibrils and curcumin components. From the examination of antibacterial and antifungal properties, the BCC films with the loading of curcumin solution at concentration of 0.5 and 1.0 mg/ml displsyed antifungal activity against Aspergillus niger with no antibacterial activity against Gram-positive and Gram negative bacteria. Characterization of inhibitory effect on growth of human melanoma cells showed that the amount of curcumin absorbed in the BCC films could be released into the cell culture medium and subsequently inhibited the growth of melanoma cancer within 3 hours. Therefore, the development of the BCC film will be useful in medical applications

title: Immobilization of Candida rugosa lipase on hierarchical porous carbon monolith

description: Candida rugosa lipase is immobilized into the column packed hierarchical porous carbon monolith. The carbon monolith is synthesized from resorcinol-formaldehyde (RF) gels by sol-gel polycondensation. The surface of carbon monoliths with (C-CO[subscript 2]) and without (C-N[subscript 2]) oxygen are obtained by thermal activation and carbonization, respectively. Physical adsorption by recirculation of enzyme solution is applied as immobilization technique. The carbon bead is also used as a support to study the optimal primary conditions (pH, ionic strength and protein loading). The optimal pH and ionic strength are obtained at 7 and 20 mM, respectively as a result of more protein binding ratio. However, optimal protein loading (1 mg/ml) shows the high lipase activity, while the protein binding ratio is low therefore there is a high possibility that all lipase on the support cannot fully work. Moreover, the effects of steric impediments and the enzyme distributions on the support are also significant. The short immobilization time of lipase on hierarchical porous carbon monolith indicates that enzymes rapidly fill the pores and attach on the surface of the porous carbon which result in rapid decrease in residual activity. Moreover, at low flow rate of enzyme solution the protein binding ratio can be improved because enzyme has more time to attach not only to enzyme and support, but also to enzyme and enzyme binding, whereas the lipase activity is low since the steric impediment and low enzyme distribution. For the kinetic behaviors of immobilized enzyme in the column, it is obviously seen that immobilization of lipase on different functional group surface support can change the reaction mechanism of enzyme. In case of immobilized enzyme in C-CO[subscript 2] column show the basic general enzyme-catalyzed reaction followed by Michaelis-Menten equation while immobilized enzyme in C-N[subscript 2] column show enzyme kinetic like a sigmoidal curve which might be cause from the solubility limit of the polar substrate in hydrophobic solvent. The C-N[subscript 2] column kinetic, K'' is lower than K[subscript m] from C-CO[subscript 2] column which this result indicates that C-N[subscript 2] column is less effective than C-CO[subscript 2] column. Furthermore, oxygenated surface of C-CO[subscript 2] column can help to improve more protein binding ratio.

title: Analysis and applications of multi-dimensional cauchy integral equation based on clifford number to scattering and radiation of electromagnetic fields

description: Integral equation methods in computational electromagnetics have been particularly attractive for researchers who need to analyse the performance of antennas in unbounded regions. These methods are formulated either from the electric field integral equation (EFIE) or from the magnetic field integral equation (MFIE). However spurious solutions can appear at some frequencies, even when the differentiation of the singular function in the kernel under the integral is approximated carefully. The problem is often avoided by using some combination of EFIE and MFIE, that is to say a combined field integral equation of CFIE. It is the purpose of this thesis to provide a particular combination of EFIE and MFIE which solves the same problem but in a different way. A new method is presented for calculating the solution of Maxwell’s equations based on the Cauchy integral and formulated in the guise of Clifford algebra. Electric and magnetic fields are embedded together as a single entity in a single Clifford number. The formulation has a geometric interpretation leading to an iterative method of solution which is easily proven as convergent and valid for both perfectly reflective and perfectly transmissive objects. The method avoids any explicit representation of current density vector on the surface of perfect electric conductors. The numerical results prove that the method can be employed to describe the behavior of scattered and radiated fields in unbounded regions of three dimensional space

title: Factors influencing quality of life among HIV-infected/AIDS patients at community hospitals in Nakhon Ratchasima province

description: The objectives of this study were to measure quality of life (QOL) among HIV-infected/AIDS patients and to examine factors influencing the QOL among HIVinfected/ AIDS patients at community hospitals in Nakhon Ratchasima province. A crosssectional descriptive was performed by using self-reporting questionnaire. All patients were outpatients who visited HIV/AIDS clinic of 24 community hospitals in Nakhon Ratchasima province. Data were collected during March 1, 2010 to March 31, 2010 from 360 HIVinfected/ AIDS patients receiving antiretroviral therapy. Their age ranged from 23-44 years old and were able to write and read Thai. The patients had received health care service from the HIV/AIDS clinic for at least three months continuously. The questionnaire had five components including Simplified Medication Adherence Questionnaire(SMAQ)(α =0.86), HIV-related symptoms questionnaire(α =0.89), Self-care behavior questionnaire(α =0.80), Social support questionnaire(α =0.84), and WHOQOL-BREF-THAI(α =0.87) which was the QOL measurement. QOL measurement was classified into four domains including physical domain, psychological domain, social relationships domain and environmental domain. Patient socio-demographics, health and treatment, self-care behavior and social support were factors that were explored the association with patients QOL by using Multiple Regression Analysis (MRA). The results showed that the total QOL score of HIV-infected/AIDS patients was moderate level. There were a significant relationship between at least one variable in patient socio-demographics, health and treatment, self-care behavior and social support with the total QOL score in this model (r=0.607,p=0.000). The variance within the predictors could explain 36.8% of variance within the total QOL score. The social support overall score had significantly largest positive correlation with total QOL score (β =0.387,p&lt;0.01). Self-care behavior overall score had significantly positive correlation with total QOL score (β =0.100,p&lt;0.05). It was also found that HIV-related symptoms score, hospital non-participated holistic care center and non-club at HIV/AIDS clinic and widowed/divorced/separated had significantly negative correlation with total QOL score (β = -0.226,-0.134,-0.097 with p&lt;0.01,p&lt;0.01,p&lt;0.05), respectively. The results presented the QOL of HIV-infected/AIDS patients receiving antiretroviral therapy at community hospitals in Nakhon Ratchasima province and its influencing factors. The results could be used for health care service development to promote supportive factors in order to improve better QOL for the patients

title: Cloning and characterization of clip domain serine proteinase, PmClipSP1, from black tiger shrimp Penaeus monodon

description: Clip domain serine proteinases (clip-SPs) are the essential components of signaling cascades in the innate immune system of invertebrates. From the Penaeus monodon EST database (http://pmonodon.biotec.or.th), a full-length cDNA of PmClipSP1 was characterized. It contains an open reading frame (ORF) of 1,101 bp encoding a predicted protein of 364 amino acids including a 25 amino acid signal peptide. The mature protein of PmClipSP1 exhibits a characteristic sequence structure of clip-SPs consisting of an N terminal clip domain and a C terminal SP domain. The mature protein and SP domain of PmClipSP1 were cloned into the pET22b(+) vector with an N terminal hexa-histidine tag fused in-frame, and expressed in Escherichia coli as 37 kDa and 28 kDa proteins, respectively. The recombinant proteins were successfully purified by Ni-NTA chromatography. Functional analysis revealed that the recombinant proteins lack a proteolytic activity and could not activate of phenoloxidase (PO) activity. Western blot analysis using the antibody raised against the SP domain of PmClipSP1 revealed that PmClipSP1 was present in hemocytes, but not in cell free plasma. Knockdown of the PmClipSP1 gene by double-stranded RNA (dsRNA) of PmClipSP1 gene, significantly reduced PmClipSP1 transcript levels, but did not significantly reduced the total PO enzyme activity, suggesting that PmClipSP1 might not involved in the proPO system. However, silencing of the PmClipSP1 gene led to a significant increase in the number of viable bacteria in the hemolymph (~2.4 fold) and in the mortality rate (59%) of shrimp systemically infected with Vibrio harveyi. These findings suggest that PmClipSP1 plays a role in the antibacterial defense mechanism of P. monodon shrimp.

title: The polyfunctionality of the word form /tôŋ/ in Thai : a cognitive linguistic study

description: The linguistic phenomenon of polyfunctionality, in which a from can perform more than one syntactic function and can denote different yet related meanings, is of particular interest from the linguistic typological, historical linguistic, and cognitive linguistic points of view. This study primarily focuses on the form /tôŋ/ in Thai, which constitutes an interesting instance of polyfunctionality as its counterparts are found to be prevalent in the Southeast Asian languages. However, it is not known how the multiple functions of /tôŋ/ are historically related as well as conceptually associated. To answer this research question, this study is thus aimed to analyze the syntax and semantics of /tôŋ/, trace the path and direction of its grammaticalization and semantic extension, and identify the mechanisms that trigger these changes. It is found that the form /tôŋ/ has two functions, the verb and auxiliary function, which can be distinguished from each other by the criteria of propositionality, distribution, control, and negation. Accordingly, the eight meaning of /tôŋ/ can be categorized into the lexical senses, which include 'coming into physical contact," "being in correspondence," "being subject to a supernatural influence," and "receiving a social obligation," and the modal meanings, which include "having an obligation to do something," "having a necessity to do something," "having a need to do something," and "having a certainly to do someting." There are six stages through which /tôŋ/ develops from its verb function to its auxiliary function, and reanalysis and analogy are mechanism responsible for this grammaticalization, though at different stages. Moreover, the semantic extension of /tôŋ/ can be broken down into three paths, and the cognitive mechanisms of metaphor and metonymy are both involved, though at different stages

title: Knowledge, Attitude, and Practice (KAP) of diabetes mellitus type II patients in multidisciplinary program at Diabetes Mellitus Clinic, Phanomphrai Hospital, Phanomphrai district, Roi-Et province, Thailand

description: The aims of this research were to describe the socio-demographic characteristics of Diabetes Mellitus Type II patients joining “Multidisciplinary Program” at Diabetes Mellitus Clinic, in Phanomphrai Hospital and to identify the level of self-care knowledge, including attitude and practice of the patients. The study also focused on the relationship between patients’ socio-demographic characteristics and the level of self-care knowledge, attitude and practice. The subjects were DM type II patients who actually joined the program for a number of 430. The study also described the factors influencing the success and the non-success of the patients in their self care through an in-depth interview with 20 subjects in 4 sample groups each of 5 persons, they were 1) nurses 2) care givers of the patients 3) successful patients for their self care 4) unsuccessful patients for their self care. Based on the result of data analysis, DM type II patients joining the program were mostly females (70.9%) with an average age of 51 years old. All of them were Buddhists. Seventy-seven point two percent of them had an educational background lower than prathomsuksa level. Furthermore, 79.8% of the subjects were married and 42.1% of them were farmers. The average patients’ household income was approximate 2,422 baht/month while their household expense was about 2,565 baht/month. Out of 38 scores on knowledge, the subjects had a mean of 22.38 scores, out of 60 scores on attitude, the subjects had a mean of 47.55 scores, and out of 69 scores on practice, the subjects had a mean of 53.88 scores. By using Chi-Square test, it found that practice had the relationship with knowledge, attitude, sex, educational level attained, occupation, field of work, frequency of blood sugar test, and duration of diabetes suffering (p &lt; .05). Factors influencing successful and unsuccessful patients in their self care practice included 1.) living near the hospital 2.) understanding the instructions and suggestions given by the program and could apply them in their daily life and 3) having a care-taker at home (for successful patients). On the other hand, the unsuccessful self-care behavior patients were influenced by 1.) living in a remote area 2.) not understanding the instructions and suggestions given thus no application on their daily living 3.) not having a care-taker at home, and 4.) having an attitude that this program could not improve their health and that there was an unequal treatment thus not motivating them to join the program
