Item Metadata only Application of 1,10-Phenanthroline and Eosin reaction for dissolved lead analysis(Mahidol University. Mahidol University Library and Knowledge Center, 2005) Wanchai Tanglearkpipat; Aurapin Eamsiri; Patana Thavipoke; Luepol PunnakantaItem Metadata only Lead and cadmium contents in organic, hygienic and conventional chinese kales(Mahidol University. Mahidol University Library and Knowledge Center, 2005) Weeraya Karnpanit; Wenika Benjapong; Songsak Srianujata; Netnapit DhananiveskulThis study is conducted to determine and compare lead and cadmium contents in Chinese kales grown under three cultivation practices. Chinese kales were collected from a number of farms in different locations and the same location from different... seasons. Closed system digestion method and GFAAS, was used as lead and cadmium determination. The study found that the median lead and cadmium levels in the hygienic Chinese kales were significantly higher than in the organic and the conventional ChineseItem Metadata only Mass flow analysis of lead in snakeskin gourami fish (Trichogaster pectoralis regan) raising pond in Samut Songkhram province(Mahidol University. Mahidol University Library and Knowledge Center, 2009) Tinnawat Kaewsawee; Raywadee RoachanakananPublication Metadata only Development of an airborne lead analysis kit and its application(2010-11-01) Pornpimol Kongtip; Pornchulee Borisut; Witaya Yoosook; Pramuk Osiri; Piangchan Rojanavipart; Mahidol UniversityWe developed a method to analyze airborne lead concentrations in the field. It was a modification of the colorimetric method using the reaction between 4(2-pyridylazo)-resorcinol (PAR) and lead with cyanex302 in an acid medium to reduce interfering... metals. The lead concentration was detected with a photometer made in Thailand. The developed method uses an impinger containing 1% nitric acid solution as an absorbing agent to collect airborne lead at a flow rate of less than or equal to one literItem Metadata only Chemical preparation and composition analysis of strontium doped lead zirconate titanate(Mahidol University. Mahidol University Library and Knowledge Center, 1999) Chutimon Ratanapeanchai; Juwadee Shiowatana; Laddawan Pdungsap; Waret VeerasaiItem Metadata only Isolation, identification and HPLC analysis of the lead compound in Gynura procumbens extract and juice(Mahidol University. Mahidol University Library and Knowledge Center, 2003) Jutamas Saengsai; Weena JiratchariyakulPublication Metadata only Development of perovskite and phase transition in lead cobalt niobate modified lead zirconate titanate system(2008-03-01) Naratip Vittayakorn; Supamas Wirunchit; Sakda Traisak; Rattikorn Yimnirun; Gobwut Rujijanagul; Mahidol University; Chiang Mai UniversityFerroelectric lead zirconate titanate-lead cobalt niobate ceramics with the formula (1 - x)Pb(Zr1/2Ti1/2)O3-xPb(Co1/3Nb2/3)O3where x = 0.0-0.5 were fabricated using a high temperature solid-state reaction method. The formation process, the structure... and homogeneity of the obtained powders have been investigated by X-ray diffraction method as well as the simultaneous thermal analysis of both differential thermal analysis (DTA) and thermogravimetry analysis (TGA). It was observed that for the binary system (1Publication Metadata only Derived 12-lead electrocardiogram in the assessment of ST-segment deviation and cardiac rhythm(2006-01-01) Darawan Chantad; Rungroj Krittayaphong; Chulalak Komoltri; Mahidol University; Faculty of Medicine, Siriraj Hospital, Mahidol University. There was a complete agreement in the interpretation of cardiac rhythm between the 2 methods (κ = 1). Analysis of ST-segment deviation of 12-lead ECG also showed a significant correlation (correlation coefficient varied from 0.62 in lead I to 0.823 in lead a...Background: There are little data on the validation of 12-lead electrocardiogram (ECG) derived by the EASI lead system used for continuous monitoring in critical care settings. Objective: The objectives of this study were to determine the accuracyPublication Metadata only Environmental lead exposure, catalase gene, and markers of antioxidant and oxidative stress relation to hypertension: An analysis based on the EGAT study(2015-02-22) Jintana Sirivarasai; Sukhumpun Kaojarern; Suwannee Chanprasertyothin; Pachara Panpunuan; Krittaya Petchpoung; Aninthita Tatsaneeyapant; Krongtong Yoovathaworn; Thunyachai Sura; Sming Kaojarern; Piyamit Sritara; Mahidol University; Kasetsart University; Health Office© 2015 Jintana Sirivarasai et al. Lead has been linked to the development of hypertension via oxidative stress. Catalase plays an important role in the disposal of hydrogen peroxide in erythrocyte and its activity was determined by CAT gene.... The aims of this study were to investigate (1) the association between blood levels of antioxidant markers such as catalase, superoxide dismutase, glutathione, glutathione peroxidase, oxidative stress-marker (malondialdehyde), and blood lead level and (2Publication Metadata only Effect of lead on IL-8 production and cell proliferation in human oral keratinocytes(2010-06-01) Thaweboon Srosiri; Poomsawat Sopee; Thaweboon Boonyanit; Mahidol UniversityObjective: To investigate the effect of lead on the production of IL-8 and cell proliferation in normal human oral keratinocytes (NHKs). Methods: NHKs were prepared as outgrowths from normal human buccal mucosa. The cells were treated with three... concentrations of lead glutamate (4.5×10-5M, 4.5×10-6M and 4.5×10-7M). NHKs grown in glutamic acid were used as control. The amounts of IL-8 secreted in the culture supernatants were evaluated at 12 and 24 h using enzyme-linked immunospecific assay (ELISA). Cell
