    The most useful part of natural aloe vera is aloe-gel (AG) and aloe-emodin(AE). AE has various pharmacological effects including, antiviral, antimicrobial and laxative activities, while AG has mainly been used as an anti- inflammable agent. Some medical activities are related to their redox activity. This paper presents a simple strategy to carry out of AG and AE based on screen printed carbon electrode (SPCE). The electrochemistry of AG and AE was investigated at pH 7.05 by cyclic voltammetry and differential pulse voltammetry. The redox mechanism is discussed. Results showed that the available working potential range for the study was the potential window between 0.60 V to -0.40 V and the peak currents of the cathodic peak increased linearly with the square root of scan rate. The peak potentials of the cathodic peaks shifted negatively as pH increased from 3.05 to 9.07. The appearance of other cathodic and anodic peak in fresh aloe vera sample indicates that the fresh aloe vera consists of several redox active species. It is concluded that a low cost, easy and convenient detection of aloe emodin was successfully achieved with this electrochemical system.

    This research was designed to assess the development of English ability in agricultural students in an agricultural machinery course. The participants were second year students in the Crop Production major of the Agricultural Technology Faculty, Rajamangala University of Technology Thanyaburi, Thailand in the academic year 2/2014. This research ran from January to April 2015. There were forty five students studying agricultural machinery. At the first meeting of the class, they were each given a one-hour pre-test to assess their ability in English. There were 100 questions and pictures. The questions and pictures of the pre-test and the post-test were the same and both tests were administered by the same researcher. The questions were recommended by three lecturers who are experts in agricultural machinery, research and English. For every question, there was a picture with the Thai name of that picture. Students then had to write the name in English. The questions covered topics such as tillage, planting, crop protection and fertilizing, as well as harvesting and processing equipment. The questions were divided into three parts: multiple choice, check list and essay. This class met twice a week for two hours each class. At the final meeting, participants were given a post-test to assess any changes. After that, the lecturer shared the answers with the students. The statistics applied in this research were frequency, percentage and mean. There were forty five students made up of sixteen males and twenty nine females. The all student average mean of the pre-test was 20.36 and the post-test was 81.6. The all student average improvement was 61.24. The average improvement for the males was 62.06 and for the females was 60.79. There was a significant difference between pre-test and post- test at a .05 level of significance.

    This study aimed to evaluate the short-term effects of the court-type traditional Thai massage (CTTM) on pressure pain threshold and pain intensity to treat patients suffering from chronic tension-type headaches (CTTHs) comparing with amitriptyline taking. A randomized controlled trial was conducted. Sixty patients diagnosed with CTTH were evenly divided into the treatment and control group. The treatment group received a 45-minute course of court-type traditional Thai massage the control group was prescribed to take 25 mg of amitriptyline once a day before bedtime lasted. The results were evaluated in short-term day 1 after intervention, The measurement consisted of Visual Analog Scale (VAS), Tissue hardness and pressure pain threshold (PPT). The results demonstrated that there was a significant decrease in pain intensity for the CTTM group at different assessment while a significant difference occurred between-group comparison (P<0.05). Moreover, the PPT of the CTTM group was significantly increased (P<0.05). It can therefore be concluded from the findings that CTTM seems to be an effective therapy for stress-related variables and increased the PPT as well as reducing pain intensity for the CTTHs.

    Integral equation has been one of the essential tools for various areas of applied mathematics. The Fredholm integral equations can be derived from boundary value problems. In this paper, we are concerned with the application of the Adomian Decomposition Method by using MATLAB program for the Fredholm integral equation of the second kind. The new computational algorithm is applied directly without using any transformation, linearization, discretization or taking some restrictive assumptions. An exact solution of the illustrative example was successfully fund using the proposed method, and the results are compared with the results of the existing methods. The Adomain Decomposition will be obtained easily without linearizing the problem by implementing the Adomain Decomposition Method by using MATLAB program rather than the standard methods for the exact solutions. The concern will be on the determination of the solution y(x) of the Fredholm integral equations of the second kind. The results indicated that the method is very effective and simple.

    The purpose of this study was to investigate the effects of traditional Thai self-massage using Wilai massage stickTM in patient with upper trapezius with myofascial trigger points. Sixty patients were randomly allocated to either a massage group using Wilai massage stickTM or a medication group. Both groups were advised to have the same daily stretching exercise. Pain intensity, pressure pain threshold (PPT) and tissue hardness were assessed at baseline, and the fifth day after the last treatment session. The results showed that after 5 days of treatment, there are significant improvement in all assessment time points (p<0.05). The adjusted post-test mean values for pain intensity, PPT and tissue hardness were significantly better in the massage group than medication group (p<0.05). We conclude that traditional Thai self-massage using Wilai massage stickTM provides better results than taking medication for patients who have upper trapezius pain associated with MTrPs.

    Elderly with less nutritional status would be susceptible to get infectious disease, immune deficiencies, reduced productivity, high risk of various complications of disease, and can even cause death. Height as the one indicator of nutritional status assessment in elderly is difficult to measured due to such conditions as osteoporosis, scoliosis, kyphosis, etc. Arm span, knee height and sitting height can be used to predict the height. However, some anthropometric measurements with different positions are not effective because of discomfort. Three anthropometric measurements in one tool like a chair can overcome the problems. The study aimed to develop the anthropometric chair (Body Mass Index/BMI Meter) for elder’s nutritional status assessment with an easy, practical measurement. The study design was cross sectional using survey method toward 300 healthy older people. Upper leg length, lower leg length, pelvic width, shoulder width, elbow height, shoulder height and patellar height were measured to design the chair. The study revealed that the male elderly had higher data anthropometric than female. The mean of anthropometric data decreased with age. The validity of anthropometric chair from the sensitivity (85-100%), specificity (70-80%), Positive Predictive Value (80-90%) and Negative Predictive Value (80-100%). The anthropometric chair can be used for assessing elders nutritional status.

    We focused on the usefulness of agricultural waste, we produced artificial paper from agricultural waste such as pineapple peel and sugar cane residue. We found that water used to boil  sugar cane residue was contained sugar and we thought that this might be used as a raw material to produce other products. Xanthan gum is  a polysaccharide that is used as an additive to increase the viscosity and stability of  food product and other products. Some micro-organisms could produce xanthan gum. This project focused on the xanthan gum production by using sugar cane residue extraction as raw material, and Xanthomonas campestris TISTR 840. We found that the incubation time of Xanthomonas campestris TISTR 840 at room temperature was 48 hours. Sugar cane residue extraction with a sugar concentration of 1.5g/100 mL and pH 7, incubated with Xanthomonas campestris TISTR 840 for 144 hours at room temperature and 200 rpm shaker speed could produce xanthan gum in highest amount, 1.5% yield. Addition of KCl at 4 g per 100 mL of incubation media removed the micro-organism. We dried xanthan gum for 30 minutes at 1000 C and collected 1.5 g of xanthan gum. The produced xanthan gum was soluble in water, 95% ethanol, 5% NaOH, 8% HCl, isopropyl alcohol and glycerol.  It was stable  in 5% NaOH, 8% HCl and 2% NaCl. The produced xanthan gum was soluble in water at a concentration of 2 g/100mL and was stable at 1200C.  Infrared spectroscopy showed that both  produced and commercial xanthan gum had a similar IR spectrum. The results indicated that xanthan gum could be produced from agricultural waste.

    In the present paper comparative study of morpho-histology of ovaries of both WT (HdrR) and P53 (-/-) of medaka (Oryzias latipes) has been done. The ovaries of adult are paired and oval-rounded in shape and are situated ventrolaterally. Histologically the ovaries consist of follicles with various stages of development, such as primodial follicle, large follicle and growing follicle. Also, the ovaries can be differentiated into outer functional regions and inner non-functional regions. The histological structure of the ovary in both strains fishes represents the generalized teleostean structure with some differences in follicles count and distribution. We conclude that, the difference recorded in the present study has an impact on the maturation inside and eggs release from the ovaries.

     Effects of the bio-extracts on controlling the Curvularia leaf spot pathogen (Curvularia. sp) and canker pathogen (Xanthomonas campestris citri) in lemon were assessed under laboratorial procedures at the Faculty of Agricultural Technology, Rajamangala University of Technology Thanyaburi [RMUTT], Thailand,  during June to July 2015. The bio-extracts were prepared through fermentation of sugar mixed with one part of water and one part of ground leaves and stems from 4 different species of plants, galangal, chili, basil and alata. Three categories of ingredients, a bio-based agar, four formulae [1-4] of the bio-extracts and distilled water were used to formulate testing media for this study. The growth rate and colony sizes of the pathogenic organisms were determined at 1, 3, 5, 7 and 14 days using a completely randomized design (CRD) experiment with four replications and five treatments. The results showed that Curvularia sp. growth was inhibited by all bio-extract formulae at the same degree from 3 days of exposure limiting all colony sizes to be smaller than 1.4 cm.  On the other hand, formulae 1 and 2 bio-extracts showed better inhibition to the growth of the citrus canker bacteria (Xanthomonas campestris citri) over the rest of treatments.  These results suggested that bio-extracts from some selected plants are capable to control plant diseases.

    This research was aimed to investigate the effect of cross-linked agents on the properties of keratin films. The films were prepared by mixing all solutions until homogeneous before pouring into polystyrene plates and dried in an oven at 40 oC for 3 days. The obtained films were characterized for their morphology and secondary structure using scanning electron microscope (SEM) and Fourier transform-infrared (FT-IR) spectrophotometer. The native keratin film had smooth surfaces with slight fragile throughout the film area. Considering among the cross-linked agent, the keratin film cross-linked with glutaraldehyde had the smoothest surfaces than others. In addition, the differences of cross-linked agents were affected on different morphology of the films. The secondary structure analysis found that random coil structures of films had been changed into β-sheet after blending with cross-linked agent. This reflected to increase of dense texture, strength and thermal stability of the films. The results could be suggested that the morphology, secondary structure and thermal stability of the keratin films were depended on content and type of cross-linked agents used.

    This work was aimed to study the effect of starch on silk fibroin (SF)/keratin (K) blend films properties. The SF and K solutions were mixed with starch, homogeneously stirred and poured into polystyrene culture plates. The mixture solution was then dried in an oven at 40 °C for 3 days. The films were then investigated for their morphology, secondary structure and thermal properties by using scanning electron microscope (SEM), Fourier transform-infrared (FT-IR) spectrophotometer, Thermogravimetric analysis (TGA). The results found that each film had different patterns of surfaces depending on ratio used. The structure of almost films co-existed with random coil and α-helix structures which resulted to increase the flexibility and of film. The structure of the films changed to β-sheet after blending between SF and K according to H-bond formation and increased thermal stability of the films. This result indicated that starch helped to decrease the crystalline structure of the film which increased their flexibility.

    Thailand is ranked among the top nations in the world for marine culture and freshwater aquaculture. Artificially propagation of the hybrid catfish Clarias gariepinus x C. macrocephalus started commercially in 1984 and has expanded throughout the country. Catfish processing as dried fish, pickled fish and fish sausage is an important farming industry providing income and boosting the local economy. Most of the processing waste is used as organic fertilizer. However there is a more valued use in the by-product as fishmeal. A simple fishmeal application process was developed from catfish processing waste (CPW). Both steaming and boiling cooking method were examined before pressing and drying processes. The composition of the fishmeal regarding protein, fat, ash and moisture content was evaluated. The results showed that both cooking processes, boiling and streaming, produced a feed with similar overall qualities. However boiling required less energy than streaming. All fishmeal samples had protein content of lower than 36%, and a fat content of about 15%. This preliminary investigation indicated that CPW was a suitable by-product for use as fishmeal.

    Routine practice of TTM may last 1 - 2 hours depending on available time of clients. We doubt that 1 hour and 2 hours may yield different results. Therefore, the purpose of this study was to investigate the immediate effects of different duration of treatment of traditional Thai massage (TTM) on stress, heart rate variability (HRV) and autonomic nervous system (ANS) function. Seventeen healthy participants were randomly allocated to receive either 1 hour of TTM (1-TTM) group or 2 hour of TTM (2-TTM) group after which they were swabbed to receive the other one with a 2 – week washed out period. Stress, HRV, and ANS function were measured before and immediately after the TTM treatment. Within-groups comparison demonstrated that stress index was decreased (p<0.05) in both groups. Stress resistance, the standard deviation of the normal-to-normal intervals (SDNN) and root mean square of successive differences (RMSSD) were increased (p<0.05) in both groups. Low frequency per high frequency (LF/HF) ratio was decreased (p<0.05) in 1-TTM group. HF and ANS activity were increased (p<0.05) in 1-TTM group whereas LF and ANS balance status were not changed in both groups. However, all of them were not significant difference for between groups comparison. We concluded that a single session of either 1 or 2 hours of TTM could decrease stress and increase heart rate variability whereas only the 1-hour TTM could increase ANS function.

    The study on the effects of resistance exercise by using elastic band found that it could increase muscle strength and physical performance, but the study of the effects of flexible stick with aerobic exercise are also less. The aim of this study was to examine the effects of flexible stick on muscle strength, muscle endurance, and flexibility in healthy subjects. Twenty-five subjects (20.5 ± 1.1 years; BMI: 21.4 ± 4.1 kg/m2) were included in this study and they performed a moderate aerobic dance with resistance training exercise by using flexible stick for 40 minutes per time which included a 5-minute of warm up, a 30-minute of exercise, and a 5-minute of cool down, 3 times per weeks, for 4 weeks. Weight, back muscle strength, abdominal muscle endurance, and flexibility were measured before and after doing the exercise. This study found that there was significant increase in back muscle strength (p=0.33), abdominal muscle endurance (p=0.001), and flexibility (p=0.0001) after exercise. However, 4 weeks of exercise did not affect on body weight. We concluded that 4 weeks of aerobic exercise with flexible stick could increase back muscle strength, abdominal muscle endurance, and flexibility in healthy subjects.

    Major Depressive Disorder has been predicted asthe second leading cause of death and disability by the year 2020. Massage is the most popular complementary and alternative medical treatment for depression. It is likely to effectively reduce anxiety. This study aimed to preliminarily examine the immediate effects of Traditional Thai Massage (TTM) on heart rate, blood pressure, and anxiety on patients with depression. The study was conducted at a district hospital, and 5 Local Health Promoting Hospitals in Khon Kaen province, Thailand. A single group pre-post design was applied. Fifteen patients diagnosed with depression participated in the study. Before and immediately after the intervention, blood pressure, heart rate, and anxiety state (using the state trait anxiety inventory; STAI) were measured. The results demonstrated a significant reduction on heart rate (mean different 5.57±4.80 bpm: p=0.001), and STAI after receiving TTM (mean score different 38.47±5.51: p < 0.001). However, no significant difference was found in blood pressure (p=0.12). TTM seems to have some beneficial immediate effects on patients with depression concerning reducing heart rate, and anxiety. A further study using randomized controlled trial with larger sample size and long-term follow-up is suggested to verify the effects.

    Fruits and vegetables are rich in vitamins, minerals and dietary fiber. However, they spoil easily and their shelf-life is very short after harvest. Especially, fruits and vegetables from organic or non-toxic agricultural fields spoiled easily as it has not contained any preservation reagent. Converted into dried powder form is easy to preserve and use as ingredients. Drying methods may affect the quality of dried fruits or vegetables. Drying with higher temperatures resulted in loss of nutrients but little studies have showed the change in dietary fiber. So, the objective of this study was to compare the effect of drying methods on dietary fiber contents in pumpkin, yardlong bean, tomato, red cabbage and guava. Natural sun drying, hot air oven drying and freeze drying were used to dry those fruit and vegetables. Then, dried fruit and vegetables were grained into a powder and analyzed for dietary fiber contents. The results show that dietary fiber contents in dried pumpkin, yardlong bean, red cabbage and guava had the same tendency, which having higher amounts of dietary fiber from natural sun dry, hot air oven dry and freeze dry, respectively. While, in tomato showed higher content in hot air oven, freeze dry and natural sun dry, respectively. According to the results, it was concluded that the condition of natural sun drying may work efficiently to get higher dietary fiber content in fruit or vegetables.

     This research investigated the effects of dietary protein ingredients from non-toxic agricultural field sources on the production quality of the Nile tilapia. The Nile tilapia (Oreochromis niloticus) is a species of freshwater fish that is of significant economic value. The experiments deployed three different dietary treatments as the tilapia feeds: pure rice bran (Treatment 1 or T1); a mixed feed of fish meal, rice bran and dried corn grains (T2); and a commercial feed (T3). The measurements of growth were taken every 14 days for a total period of 120 days, while the survival rate and the meat quality parameters with respect to color values (L*, a* and b*), texture and sensory preference were determined at the start and termination and compared. The findings revealed a significant difference in the growth weights (p£0.05), with T2 achieving the greatest weights (75.4±26.0 g). The average daily growth (ADG) and the feed conversion ratio (FCR) were also highest for the T2 group, with an average of 1.27±0.12 g/day (p£0.05) and 1.74±0.42 (p>0.05), respectively. Overall, the composition of the dietary protein ingredients from non-toxic agricultural field sources significantly influences on the meat quality and sensory preference of O. niloticus.

    The objectives of this work were to study the total phenolic contents (TPC) and antioxidant activity of methanolic extracts of six fresh Thai curry. The TPC of the fresh Thai curry were found in the range of 0.989-1.1132 mg GAE/mg of extract. Among the curry, red curry present the highest amount of TPC. Antioxidant activity of the extracts was measured by DPPH-radical-scavenging assay, lipid peroxidation inhibition and metal ion chelating assay. The Thai red curry extract exhibited the highest inhibition of lipid peroxidation of linoleic acid emulsion (81.41±0.55%), radical-scavenging activity (IC50 = 0.0476 mg/mL). In addition, the fresh of Thai red curry had the highest of metal chelating activity (76.58±0.72%). However, all of fresh Thai curry showed metal chelating similar potential activity and not significant statistical differences. These results suggest that the fresh Thai curry had interesting antioxidant activities and should be propose as potential sources of safe natural antioxidants and preservatives for curry industry.

    The free throw is the single most important shot in the game of basketball. The factors influencing the ability of the basketball free throw accuracy consisted of skill, standing balance, muscle fatigue, and concentration. Massage has been used for reducing muscle fatigue in sports which may affect standing balance, concentration, and free throw accuracy. However, there were no research studies available on these regards. The aim of this study was to determine the effects of traditional Thai massage (TTM) on standing balance, muscle fatigue, concentration, and basketball free throw accuracy. Thirty male basketball athletes were randomly allocated into either traditional Thai massage (TTM) group or Control (C) group after which they were swabbed to receive the other one with a 2-week washed out period. Standing balance, perceived muscle fatigue, concentration, and basketball free throw accuracy were measured before and the next day after receiving either 1-hour session of TTM or rest. The study found that balance and concentration were significantly increased (p<0.05) only in the TTM group. Fatigue was significantly decreased (p<0.05) in TTM group while it was significantly increased (p<0.05) in C group. Between-group comparison revealed that standing balance and fatigue were significantly different (p<0.05). However, free throw accuracy was not changed in both within- and between- groups comparison. We conclude that a 1-hour session TTM could increase standing balance, decrease muscle fatigue, and increase concentration but could not affect free throw accuracy in basketball athletes.
