The synthetic process of an iron-polysaccharide complex drug substance was improved to make it more suitable for industrial scale production. The complex was synthesized by reacting FeCl3 and syrup in basic solution followed by separation and purification by ethanol precipitation and low speed centrifugation. Process conditions were optimized using response surface methodology (RSM) based on th...

A series of six novel heterocyclic chalcone analogues 4(a-f) has been synthesized by condensing 2-acetyl-5-chlorothiophene with benzaldehyde derivatives in methanol at room temperature using a catalytic amount of sodium hydroxide. The newly synthesized compounds are characterized by IR, mass spectra, elemental analysis and melting point. Subsequently; the structures of these compounds were dete...

Time has placed a halo of honour round this little book first published in 1881. It gives to-day, as it gave then, all that can be done in a case of poisoning. The use of stomach tube has been encouraged even in the case of con-osive poisons. If the gullet and the stomach have perished before the arrival of the medical man the patient is going to die in any case. Doubt has been cast on the effi...

A fluorescence-quenching method is developed to assess the effect of pH on the coagulation mechanism of humic acids (HA) reacting with metal ions. A polyferric sulfate (PFS) synthesized in our laboratory is adopted as the coagulant to simplify the hydrolysis process and increase the experimental precision. The following results are discovered. When the concentration of PFS increases from 2 to 1...

BACKGROUND Iron-deficiency anemia is the most common nutritional cause of anemia in pregnancy and is often responsible for puerperal anemia. Puerperal anemia can impair postpartum maternal and neonatal well-being. OBJECTIVE To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III...

in this study, we offer a general view at the area of fuzzy modeling and fuzzymodels, identify the visible development phases and elaborate on a new and promisingdirections of system modeling by introducing a concept of granular models. granularmodels, especially granular fuzzy models constitute an important generalization of existingfuzzy models and, in contrast to the existing models, generat...
