title: Inhibitory effect of phyllanthus emblica aqueous extract on recombinant human cytochrome P450

description: Phyllanthus emblica Linn. is a plant in family Euphorbiaceae. Several parts of P. emblica are used for antitussive, anti-inflammatory and antipyretic. Its fruits are the rich source of ascorbic acid. From the past to present, investigations regarding pharmacological effects of P. emblica are still ongoing. The aim of this study is to investigate the inhibitory effect of P. emblica aqueous extract on recombinant human cytochrome P450 such as CYP1A2, CYP2C9, CYP2D6, CYP2E1 and CYP3A4 in vitro study. IC50 of the extract on each CYP isoform was determined. The mechanism-based inhibition was investigated using the IC50 ratio. Then, the type of reversible inhibition was investigated using Lineweaver-Burk plot for determining Ki value, the inhibition constant for predicting of herb-drug interaction. The result showed that the extract exhibited inhibitory effects on CYP1A2, CYP2C9, CYP2D6, CYP2E1 and CYP3A4 with IC50 ± SE of 310.27 ± 5.07, 194.72 ± 2.94, 589.52 ± 14.32, 310.27 ± 15.06 and 325.54 ± 7.44 µg/mL, respectively. Inhibitory effect of the extract on CYP3A4 was shown to be mechanism-based with an IC50 ratio of more than 1 (1.029). Also, the extract exhibited CYP3A4 reversibly by the non-competitive type with the Ki ± SE value of 117.11 ± 1.55µg/mL. Results from this study provide preliminary data for predicting the possibility of drug interaction when this extract is co-administered with other medicines that are metabolized by CYP enzymes. Further in vivo study is needed so as to assure the safety profile before using the extract clinically without herb-drug interaction.

title: Investment risk assessment in plastic injection molding machine replacement

description: The purpose of this research is to assess investment risk in plastic injection machine replacement in a company that its production cost is increasing continuously which causes company to lose competitive advantage and profit margin. Under the given research requirements, the machine replacement analysis is conducted by comparing existing production system with new production system in various aspects consisting of economic life cycle analysis, cost of quality analysis, incremental B/C ratio analysis, feasibility study and risk assessment of new production system. The results of these analysis show that it is appropriate to replace the existing system with the new one. The payback period of the new production system is about 10 months with 747 million baht of net present value. In addition, risks that might affect the new production system are identified and evaluated. By using Pareto technique, 3 critical risks out of 14 preliminary identified risks have been determined. They are raw material price fluctuation, product price fluctuation and market recession. Then the risk team has generated 4 preventive action plans which are skill training, communication between the company and its customers as well as its raw material suppliers and cross-department meeting. Although the preventive action plans have been generated, the risk management has to be monitored and controlled continuously.

title: Method development for preconcentration and determination of mercury in water and air

description: The method for preconcentration and determination of trace mercury in water and air were developed. MCM-41 and silica gel chemically functionalized with 2-(3-(2-aminoethylthio)propylthio)ethanamine were synthesized and used as selective adsorbents for mercury. The functionalized silica gel was further applied to a fully automated sample preconcentration and cold vapor introduction, which was coupled to an atomic absorption spectrometer. The performance of the system was investigated under optimum conditions using the spiked sample containing 0.20 and 4.00 g L-1. The percentage recovery and the precision (%RSD) of the method were in the range of 85 – 106 % and 5.5 - 12 %, respectively. The accuracy of the proposed method was tested by using certified reference materials (HG95-3 and HG 95-10) and the method gave the analytical results with acceptable accuracy.An automated atmospheric mercury analyzer based on the dielectric barrier discharge (DBD) atomic emission technique was developed. Several types of radiation detector were investigated. The system was operated continuously over 7 days to test the system performance. The limit of detection was 0.12 ng L-1 and the linear range extended at least to 6.6 ng L-1, typical RSD values for determination at the single digit ng L-1 level ranged from 2.8 to 4.9 %. The system was successfully applied to determine the atmospheric mercury at fluorescence lamp recycling plant area.

title: Microstructural and dielectric properties of calcium copper titanate thin films prepared by a sol-gel method

description: The high dielectric perovskite CaCu3Ti4O12(CCTO) has recently attracted much attention. We have successfully prepared CCTO thin films by a sol-gel spin coating technique. We synthesized CCTO films on different types of substrates in order to study the effect of substrate types on the microstructure and dielectric properties of the films. The CCTO film grown on LaAlO3 tended to be an epitaxial film. The CCTO films deposited both on LaAlO3 and NdGaO3 substrates showed {200} preferred orientation with the lattice constant of 7.391 Å and 7.390 Å, respectively. However, the films grown on Si were polycrystalline with the lattice constant of 7.380 Å. The Field Emission Scanning Electron Microscopy results indicated that the grain size of the films grown on Si, LaAlO3 and NdGaO3 were 58, 40 and 44 nm, respectively. For the Fe doped CCTO film, the characteristic peaks of CCTO were preserved as long as the concentration of the Fe-doped did not exceed 6% by weight. The existing of Fe in our films present Fe3+ oxidation state which were confirmed by X-ray Absorption Spectroscopy result. The dielectric constant of the CCTO film grown on Al2O3 and NGO substrates decrease with the increasing of frequency 40 kHz up to 1 MHz. The dielectric constant is high about 1044-1020 with low dielectric loss about 0.0263-0.0134 for the film deposited on NGO substrate. Moreover, the dielectric constant of the film deposited on NGO can be tuned with tunability of 2.6% by applying an electric field of 105 V/m

title: Modification of QuEChERS method for determination of morphine and codeine in urine

description: One way of proving persons taking heroin is the detection of trace amounts of morphine and codeine in the defendant’s urine. The test may be complicated, by being time consuming and requiring a large amount of samples. The samples must be enriched enough for the test. A QuEChERS (Quick Easy Cheap Effective Rugged and Safe) method is literally introduced for use in the test process. It has been successfully modified for the urine tested samples by using an alumina-N sorbent as the dispersive solid-phase extraction to reduce matrix interferences and to achieve the enrichment. The treated sample was detected by a High Performance Thin Layer Chromatography (HPTLC) and Gas chromatographymass spectrometry (GCMS). The proposed procedure required 5 mL and 1 mL of a urine sample, respectively. It was found that the limit of morphine and codeine detection by HPTLC were 100 ng/mL and 300 ng/mL, respectively, and by GCMS were 39.1 ng/mL and 40.6 ng/mL, respectively. This method is quick, easy, cheap, effective, rugged, safe, and applicable in a routine work. Especially for the HPTLC method, with the QuEChERS, is cheaper than other methods. This proposed method solves the problem of a limited amount of samples. The remaining sample can be used for further confirmation procedures as required by Thai legislation.

title: Molecular analysis of Phyllanthus spp. in Thailand based on rapd and dna sequencing

description: The genus Phyllanthus (Euphorbiaceae) is distributed in tropical and subtropical regions, and its members are widely used as medicinal plants in many countries. Plants in this genus are important source of natural products and bioactive compounds. The medicinal effects of Phyllanthus are diverse including antipyretic, analgesic, anti-inflammatory, antihepatotoxic and antiviral activity. In this study the genetic variation of twenty-three Phyllanthus species existing in Thailand were analyzed. Random amplified polymorphic DNA (RAPD) markers were used to discriminate between Phyllanthus species. Nine out of eighty arbitrary primers were screened for DNA polymorphism. Primer OPS-01, OPS-03, OPS-07, OPS-08, OPS-12, OPS-19, OPD-02, OPD-04, and OPD-07 produced unique DNA fingerprints that individuated the twelve Phyllanthus species. In this study, we also analyzed the nucleotide sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA. Furthermore, a simple protocol to discriminate three important medicinal Phyllanthus species, P. amarus, P. debilis, and P. urinaria, was developed using a Polymerase Chain Reaction- Restriction Fragment Length Polymorphism (PCR-RFLP) method based on ITS sequences and successfully applied to the crude drug samples obtained in Thai markets.

title: New boronic acid/fluorescein based fluorescent and colormimetric sensors for copper and cyanide ions

description: A major aim of this research is to synthesize new sensors containing fluorescein and boronic acid moieties, F-oBOH F-mBOH, and F-pBOH, for detection of copper and cyanide ions. Initially, the complexation studies of sensors with various cations in acetonitrile, evaluated by UV-vis spectrophotometry and naked-eyes detection, were found that F-oBOH, F-mBOH, and F-pBOH showed a high selectivity toward copper(II) ion. Then, the complexation abilities of three sensors with copper(II) ion were measured by using UV-vis and fluorescence titration techniques. The log values evaluated by UV-vis titration of F-oBOH, F-mBOH, and F-pBOH were 6.67, 8.87, and 9.88, respectively; while, the log values evaluated by fluorescence titration of F-oBOH, F-mBOH, and F-pBOH were 8.02, 8.48, and 11.53, respectively. In addition, we studied all of three sensors in aqueous media and discovered that sensors were hydrolyzed by water. Therefore, we designed the new strategy to prevent the hydrolysis approach by adapting coordination nanoparticles network (F-oBOH-AMP/Gd3+ CNPs). It displayed the enhancement of fluorescent signal after adding copper ion following by cyanide ion. The log K value of F-oBOH-AMP/Gd3+ CNPs copper (II) with cyanide ion is 3.97. Additionally, the detection limit of F-oBOH-AMP/Gd3+CNPs copper(II) with cyanide anion detected by naked-eyes and fluorescence technique was 20 M and 4.03 M, respectively. Furthermore, they possess a high selectivity for cyanide ion compared to other competitive anions.

title: Organ doses in brain and body multidetector computed tomography examination

description: Computed tomography (CT) examinations are an essential part of the diagnostic procedures in radiology. Multidetector CT (MDCT) is becoming more and more widespread due to advances in technology. Evaluation of radiation risk and benefit is important in all radiation diagnostic procedures. The organ and effective doses are the important quantities to assess radiation risk, but an individual CT patient dose is not possible to be measured exactly. The objective of this study is to determine organ doses and effective doses in brain, chest and abdomen protocols by Monte Carlo method using ImPACT CT Patient Dosimetry Calculator version 1.0. The patient data was collected from 64 slices GE VCT scanner of 60 cases in each examination in adult male and female. The accuracy of dose calculation was verified with thermoluminescent dosimeters (TLDs) measurement in Alderson Rando phantom. The verification of the effective dose estimated from TLD dose measurements for chest and abdomen protocol showed a good agreement within 4.3% with the Monte Carlo simulation while the brain protocol showed the difference of 20.5%. For patient data collection, the average patient scan lengths were 13.4±0.65 cm for brain, 34.3±4.99 cm for chest and 41.4±3.13 cm for whole abdomen examinations. The high organ doses in irradiated field showed 37 mGy in brain and 43 mGy in eye lenses for brain examination, the dose ranged from 12 to 19 mGy occurred in lung, breast, esophagus, adrenal gland, thymus and heart for chest examination and the dose ranged from 16 to 22 mGy occurred in colon, stomach, bladder, liver, adrenal gland, small intestine, kidney, pancreas, spleen, ovaries, uterus and prostate for whole abdomen examination. The average effective doses were 1.6±0.07 mSv, 7.2±1.03 mSv and 9.7±0.46 mSv for brain, chest and whole abdomen examination, respectively. The effective doses were about 3 to 25% lower than the ICRP recommendation. The estimated fatal cancer risks were about 1, 4 and 5 cases for 10,000 populations in brain, chest and whole abdomen examinations, respectively. The scan length is one of the variable factors that make the high organ and effective doses in CT examination. The more series of examination is another factor to increase the CT doses. Estimated organ and effective doses provide an approximate indicator of potential detriment from radiation for radiologists and physicians to use as the parameters in evaluating the frequency of scan and suitable scan length.
