This Application Note describes the development of a method for the separation of four stereoisomers, which were derived from a compound with two steric centers. The method was developed using an Agilent 1260 Infinity Analytical Supercritical Fluid Chromatography (SFC) System with Agilent ChemStation Method Scouting Wizard software. The developed method was used to compare the ratio of stereois...

Effects of acute inhibition of glucose-6-phosphatase activity by the chlorogenic acid derivative S4048 on hepatic carbohydrate fluxes were examined in isolated rat hepatocytes and in vivo in rats. Fluxes were calculated using tracer dilution techniques and mass isotopomer distribution analysis in plasma glucose and urinary paracetamol-glucuronide after infusion of [U-(13)C]glucose, [2-(13)C]gly...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
برای آگاهی از وضع نوسانات سطح آب زیرزمینی در مناطق خشک و نیمه خشک، لازم است پیش بینی دقیقی از نوسانات انجام شود. سری های زمانی به عنوان مدل خطّی جهت تولید داده های سطح آب مصنوعی و پیش بینی آینده سطح ایستابی آبخوان کاربرد دارد. به کمک نرم افزار 17 minitab و با استفاده از داده های ماهانه 20 سال (1390-1370) عمق سطح آب زیرزمینی 25 حلقه چاه پیزومتریک دشت، مدل های سری زمانی هریک از چاه ها انتخاب گردید...
This Application Note used hen egg white lysozyme as a model protein for purifi cation and biophysical characterization of PEGylated proteins. PEGylation to the N-terminus of lysozyme in a site-specifi c manner was achieved using PEG-propionaldehyde derivatives with a molecular weight of Mw 20,000. A semi-preparative RP-HPLC method for the purifi cation of PEGylated lysozyme was developed using...
BACKGROUND To perform a comprehensive study on the relationship between vitamin D metabolism and the response to interferon-α-based therapy of chronic hepatitis C. METHODOLOGY/PRINCIPAL FINDINGS Associations between a functionally relevant polymorphism in the gene encoding the vitamin D 1α-hydroxylase (CYP27B1-1260 rs10877012) and the response to treatment with pegylated interferon-α (PEG-IFN...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
