The chemical step in the chemoenzymatic synthesis of bioengineered heparin has been examined and optimized statistically using a response surface methodology. A four factor, two level full factorial design experiment and a three factor Box-Behnken design were carried out. The goal was to establish a method to prepare N-sulfo, N-acetyl heparosan of the desired N-acetyl content, number average mo...
BACKGROUND Amoxicillin is a commonly used antibiotic which has a short half-life in human. The frequent administration of amoxicillin is often required to keep the plasma drug level in an effective range. The short dosing interval of amoxicillin could also cause some side effects and drug resistance, and impair its therapeutic efficacy and patients' compliance. Therefore, a three-pulse release ...
BACKGROUND In this research, the removal of natural organic matter from aqueous solutions using advanced oxidation processes (UV/H2O2) was evaluated. Therefore, the response surface methodology and Box-Behnken design matrix were employed to design the experiments and to determine the optimal conditions. The effects of various parameters such as initial concentration of H2O2 (100-180 mg/L), pH (...
