title: Petrogenesis of amphibolites in Amphoe Wang nam khiao area, Changwat Nakhon Ratchasima

description: Amphibolites around Ban Yup I Pun and Ban Nong Mai Daeng in Wang Nam Khiao area have sparsely exposed within an area of about 65 km². Over 40 rock samples were collected from various amphibolite exposures, for petrographic investigation, whole-rock geochemical and mineral chemistry analyses. Based on petrographic features, these rock samples can be classified as coarse-grained granular amphibolites, layered amphibolites and migmatitic amphibolites. Geochemically, these amphibolites appear to have mafic igneous origin with a signature of oceanic remnant; moreover, indication of E-MORB-type within arc affinities is also observed for their initial provenance. Chondrite-normalized rare earth element (REE) and other trace element patterns supported that amphibolites should have been derived from island arc-related E-MORB. Regarding to P-T calculations, these amphibolites clearly belong to amphibolites facies with estimated P-T of about 686+32°C and 4.2+ 1 Kbar.

title: Formulation development of multilayer sustained release tablets of sodium valproate combined with valproic acid

description: The purpose of this study was to formulate and evaluate the effect of different polymers on drug release from sodium valproate matrix tablet and develop multilayer sustained release tablets that composed of sodium valproate only and combined with valproic acid. They were prepared by direct compression method using various amount of colloidal silicon dioxide (2.5-5%w/w) as an adsorbent, talcum, dibasic calcium phosphate as excipients. The polymers used were:, ethylcellulose, HPMC E4M, HPMC K15M, xanthan gum, carrageenan, sodium alginate, Kollidon® SR and Eudragit® RSPO (5-20%w/w). Among the eight polymers, HPMC K15M led to more retardation of drug release. The concentration of HPMC K15M employed in tablet formulations affected drug release from matrix tablets. Then, HPMC K15M was also used as a rate controlling polymer in the outer layers. The drug released from multilayer formulations were sustained for 24 hours. The formulation that composed of only sodium valproate released drug from tablet faster than that composed of sodium valproate combined with valproic acid. Drug release profiles of multilayer sustained release tablets of sodium valproate and those of sodium valproate combined with valproic acid best fit to zero order release model, while the mechanism of drug release was non-fickian diffusion.

title: Development of a new analytical method for determination of Asiaticoside content in Centella Asiatica

description: Asiaticoside, an active triterpene glycoside in Centella asiatica L., has weak UV absorption due to the lack of chromophore in its structure, and this causes an ineffective asiaticoside analysis by standard UV-Vis HPLC. In this study, a simple TLC-densitometic method was developed for rapid and effective analysis of the triterpenoid glycosides in C. asiatica crude extracts and its commercial products. This new analytical method is based on the derivatization of asiaticoside structure with 2-naphthol acid reagent on a TLC silica gel plate to form a chromophore-containing compound that can be detected by UV-visible based TLC-densitometric analysis (λmax at 530nm). In practice, crude C. asiatica extracts were prepared from the plant materials under sonication with 80% (v/v) methanol. The analysis was then performed on a silica gel 60 F254 TLC plate (20x10 cm.) with chloroform/methanol/water (30:15:1.2 volume ratio) system as the mobile phase. Densitometric analysis is performed at 530 nm after post-chromatographic derivatization with 2-naphthol sulfuric acid reagent (brownish band for glycoside). This new method showed good accuracy comparable to the UV-HPLC method but is more sensitive and effective. The linear range for the analysis of asiaticoside was 100-1000 ng/band (r2≥0.99) with good precision and accuracy (1.15- 1.9 %RSD, 98-104% recovery) and the values of asiaticoside contents determined by the developed TLC method and HPLC method were well correlated in range 99-101%. The developed densitometric TLC appeared to be simple, accurate, precise and fast as eighteen chromatographic runs could be performed simultaneously per plate within 15 minutes.

title: Biodiesel production via heterogeneous base catalyst from seashells continuous fixed bed reactor

description: The present thesis was studied by formulation of heterogeneous base catalysts from waste mixed seashells for transesterification of palm oil with methanol in a fixed bed reactor. The catalysts were prepared by dissolution-precipitation method. Typically, the calcined seashells were mixed with zinc nitrate as a strength component, aluminium oxide as a supported material and hydroxyethyl cellulose (HEC) as a plasticizer in a solution of nitric acid. Effects of the formulation conditions in extrudates catalyst, including extruder type, amount of HEC and calcination temperature on the physicochemical and the catalytic properties were investigated. The properties of the catalysts were studied by X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric/ differential thermal analysis (TG/DTA), N2 adsorption-desorption measurement and CO2-pluse chemisorption analysis. The suitable condition for the catalyst preparation is the weight ratio of seashells/Al2O3 with 1:1, the amount of HEC with 3 wt.% of total solid, single screw extruder and calcination temperature of 300 °C. The extrudate catalysts attained gave the highest and stable FAME yield (95 wt.% and 24 h, respectively) attained from the transesterification under the suitable transesterification condition at methanol/oil molar ratio, 30; temperature, 65 ºC; premixing with methyl esters, 30 wt.% of catalyst extrydates and total flow rate, 2.0 mL min-1.

title: Simulation of autothermal biomass gasification using supercritical water

description: Depletion of fossil fuel and environmental concerns stimulate the use of clear and renewable energy. Biomass is regarded as a potential energy source and can be efficiently converted to a useful synthesis gas via incomplete combustion in a gasification process. However, the thermal gasification causes a formation of tar and requires high energy input when wet biomass is used. Supercritical water gasification (SCWG) is a possible way to cope with these difficulties because supercritical water behaves like many organic solvents so that organic compounds have complete miscibility with supercritical water. The objective of this study is to examine the performance of a biomass gasification process in supercritical water condition at energy self–sufficient operation, compared with a conventional gasification process. Modeling of the biomass gasification is performed using a process flowsheet simulator. Two different biomass feedstock: rice straw (low water content feedstock) and hyacinth (high water content feedstock), are considered in this study. Simulations are carried out to study effect of key operational parameters, such as gasification temperature, feedstock concentration and pressure, on the gaseous product composition and the efficiency of the gasification process under a energy self-sufficient operation, where no external heat input is required. The simulation results show that the conventional gasification is suitable process when biomass with low moisture content like rice straw is used as feedstock, whereas for biomass with high moisture content like water hyacinth, the application of the supercritical water gasification process is the appropriate option. To determine an optimal operating condition for the supercritical water gasification process, a response surface methodology (RSM) based on a central composite design (CCD) is used in this study.

title: Functional characterization of a clip domain serine proteinase PmClipSP2 from the 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 shrimp Penaeus monodon EST database (http://pmonodon.biotec.or.th), a full-length cDNA of PmClipSP2 was identified and characterized. It contains an open reading frame of 1,107 bp encoding a predicted protein of 369 amino acids including a 25 amino acid signal peptide. The predicted molecular mass of the mature protein is 40.18 kDa. PmClipSP2 exhibits a characteristic sequence structure of clip-SPs consisting of an N terminal clip domain and a C terminal SP domain. Knockdown of the PmClipSP2 gene by double-stranded RNA (dsRNA) of PmClipSP2 gene, significantly reduced the PmClipSP2 transcript level and significantly reduced the total phenoloxidase (PO) activity. Silencing of the PmClipSP2 gene led to the 100% mortality rate and high number of bacteria in hemolymph of shrimp systemically infected with Vibrio harveyi. Interestingly, injection of microbial cell wall components had lethal effect on the PmClipSP2 knockdown shrimp that showed significantly decreased in the number of hemocytes. Functional analysis revealed that the recombinant PmClipSP2 could bind to β-1,3-glucan and LPS and activates phenoloxidase (PO) activity and has a proteolytic activity. Western blot analysis using the antibody raised against the rPmClipSP2 revealed that PmClipSP2 was present in hemocytes, but not in cell free plasma. Taken together, these results suggest that PmClipSP2 directly binds to bacterial cell wall components and activates the proPO system through the proteinase cascade and it probably involves in the hemocyte homeostasis by neutralizing LPS toxicity.

title: Infectivity and cell death of microglia in response to Japanese encephalitis virus

description: Japanese encephalitis virus (JEV), an arbovirus that belongs to the family Flaviviridae, is endemic to large parts of Asia and Pacific. Even though neurons have been proposed to be the principle JEV target cells in the central nervous system, microglia are activated and secreted many mediators in response to JEV infection. Recently, autophagy, a cellular process involved in the degradation of organelles and aggregated long-lived proteins, has been reported to play a significant role in viral infection. This study aimed to determine the involvement of autophagy in response to JEV infection in human microglial (CHME-5) cells. Upon JEV infection at a multiplicity of infection of 10, a small deficit in total cell number, compared to that of mock-infected CHME-5 cells was observed. However, with the multiplicity of infection of 100, a significant reduction in total cell number was observed since day 2 post infection. Interestingly, the percentage of cell death, determined by tryptan blue dye exclusion assay, was relatively the same (less than 10%) in both levels of multiplicity of infection, indicating a slower proliferation rate in JEV-infected microglial culture with a higher multiplicity of infection. By immunocytochemistry, JEV virions were clearly detected in cytoplasm of microglial cells, with an estimated of 78% infectivity at day 2 post infection. Electron micrographs demonstrated autophagosomes with JEV virions. Besides, an increase in the expression of LC3-II in response to JEV infection was detected by indirect immunofluorescence and western blotting. In addition, inhibition of autophagy, using 3-methyladenine, led to a reduction of the JEV production suggesting autophagy mediated viral replication. Collectively, these results indicate that human microglia are susceptible to JEV and autophagy is induced during JEV infection.
