Item Metadata only Effects of chloroform-methanol extraction and periodic acid oxidation on performance of the lipid associated sialic acid assay in detection of head and neck cancers(Mahidol University. Mahidol University Library and Knowledge Center, 2001) Wirawat Jalayondeja; Vipa Boonkitticharoen; Boonchu KulapaditharomPublication Metadata only Chemical degradation of epoxidized natural rubber using periodic acid: Preparation of epoxidized liquid natural rubber(2005-01-05) P. Phinyocheep; C. W. Phetphaisit; D. Derouet; I. Campistron; J. C. Brosse; Mahidol University; Universite du Maine Le Mans - LavalOxidative degradation of epoxidized natural rubber (ENR) was effectively performed in latex phase by using periodic acid at 30°C. The ENR was prepared from the epoxidation of natural rubber in latex phase using performic acid generated in situ... by the reaction of hydrogen peroxide and formic acid. The prepared ENR latex was subsequently treated with periodic acid. It was found that the higher the amount of the periodic acid employed the faster the molecular weight of the ENR decreased.

Mahidol University Library and Knowledge Center, 2023) Uraiwan Wutisilp; Phienvit Tantibhedhangkul; Sakorn Dhanamitta; Naiphinich KotchabhakdiPublication Metadata only Activation of proenzyme of acidic protease from human seminal plasma(1976-12-08) Montri Chulavatnatol; Pintip Ruenwongsa; Mahidol Universityto the proenzyme. Between pH 4.5 and 5, the rate deviated from the first-order with an initial lag period which can be abolished by adding an excess amount of the acidic protease or pepsin. The extent of the activation was complete between pH 2 and 3 and became... an initial lag period. Addition of acidic protease did not change the rate of self activation or the lag period. © 1976.Publication Metadata only Obesity and serum uric acid in secondary school-age students of srinagarindra the princess mother school, Phayao, Thailand(2018-04-01) Wanpen Suttikomin; Preeya Leelahagul; Suphawan Khamvang; Chamnong Chaimongkol; Nanticha Chaiwut; Faculty of Medicine, Ramathibodi Hospital, Mahidol University; Srinagarindra The Princess Mother Schoolstatistically significantly higher serum uric acid levels than those in girls as well as serum uric acid levels at late adolescent period in both sexes were statistically significantly higher than those at early adolescent period. Conclusion: On multivariate.... This indicated that early nutritional management and encourage obese adolescents to weight and serum uric acid reductions are important for the prevention of diet-related chronic diseases in their adult period.Publication Metadata only Comparison of 24-hour recall and 3-day food records during the complementary feeding period in Thai infants and evaluation of plasma amino acids as markers of protein intake(2021-02-01) Kulnipa Kittisakmontri; Julie Lanigan; Areeporn Sangcakul; Thipwimol Tim-Aroon; Pornchai Meemaew; Kanticha Wangaueattachon; Mary Fewtrell; Faculty of Medicine Ramathibodi Hospital, Mahidol University; UCL Great Ormond Street Institute of Child Health; Chiang Mai Universityduring the weaning period is limited, especially in lower-middle income countries. The primary aim of this study was to evaluate relative validity of a 24-h recall method (24-HR) using a 3-day food record (3-DFR). A secondary aim was to investigate... association between protein intake from 3-DFR and plasma amino acids as a potential protein biomarker. Methods A multicentre, prospective cohort study was conducted in Chiang Mai, Thailand from June 2018 to May 2019. Food consumption data were collectedItem Metadata only Logistic regression approach to determine the association of litter contamination, acid administration and feed withdrawal period on Salmonella contamination in broilers(Mahidol University. Mahidol University Library and Knowledge Center, 2004) Orawan Fakkham; Piangchan RojanavipartPublication Metadata only Effect of poly(D-lactic acid) and cooling temperature on heat resistance and antibacterial performance of stereocomplex poly(L-lactic acid)(2020-01-01) Yeiangchart Boonluksiri; Benjaphorn Prapagdee; Narongrit Sombatsompop; Faculty of Environment and Resource Studies, Mahidol University; King Mongkut s University of Technology Thonburi© 2020 Wiley Periodicals, Inc. Stereocomplex nucleated polylactic acid was prepared by the addition of poly(D-lactic acid) (PDLA) in poly(L-lactic acid) (PLLA) under various cooling temperatures by monitoring the mechanical properties and heat... resistance. Antibacterial performance against the growth of Escherichia coli on PLLA/PDLA doped with various contents of 2-hydroxypropyl-3-piperazinyl-quinoline carboxylic acid methacrylate (HPQM) was also evaluated. The results suggested that a smallPublication Metadata only Preparation and physicochemical properties of dialdehyde tapioca starch(2005-04-01) Rungtiwa Wongsagon; Sujin Shobsngob; Saiyavit Varavinit; Mahidol UniversityTapioca starch was oxidized by periodic acid (sodium metaperiodate plus hydrochloric acid) to form dialdehyde tapioca starch (DAS). The influence of periodate concentration (NalO4, 0.05 N, 0.1 N, 0.2 N and 0.3 N) on the physicochemical properties... increased linearly with the increasing of periodate concentration. X-ray diffraction patterns of DAS remained unchanged after periodate oxidation whereas the relative crystallinity decreased as periodate concentration increased.

Monique Paricharttanakul; Polkit Sangvanich; Jisnuson Svasti; Chantragan Srisomsap; Chulabhorn Research Institute; Chulalongkorn University; Chulabhorn Graduate Institute; Mahidol UniversityProteins involved during storage of Curcuma longa have not been investigated in detail. Proteins and nucleic acids are considered to be essential for the sprouting period. As numerous applications of proteomic approaches have been reported in many... to enrich the low abundance proteins in the pH range of 5.4-10 and improve the separation of those proteins in the acidic range from 3-5.4. Samples were drawn at seven-day intervals from harvest until the commencement of sprouting. The proteomic patterns
