Which model should be selected to analyze the experimental data among many adsorption kinetic models?

For many years adsorption kinetics has been investigated, the development of kinetic model has been proceeded in order to obtain the particular kinetic model which better agree with the experimental data. As the result, dozens of kinetic models have been established and used individually despite there are a certain relationship between them. Students often ask which model should be selected to analyze their experimental data among different adsorption kinetic models. In order to clarify dependence relationship and similar degree between adsorption kinetic models, we calculated and compared. Calculation results were successfully compared with the correlation between them and an education method for adsorption kinetic study was proposed. This method can help graduate students of chemical engineering to understand the calculations on kinetics.</p

Differential influences of LDL cholesterol on functional outcomes after intravenous thrombolysis according to prestroke statin use

This study aimed to elucidate whether low-density lipoprotein cholesterol (LDL-C) levels differentially affect functional outcomes after intravenous thrombolysis (IVT) depending on prestroke statin use. Patients with acute ischemic stroke treated with IVT were categorized into low, intermediate, and high LDL-C groups based on LDL-C levels at admission (&lt; 100/100-130/ &gt; 130 mg/dl, respectively). Multivariable logistic regression analyses were performed to explore the relationships between LDL-C and clinical outcomes (good outcomes at 3 months, modified Rankin Scale scores 0-2). The interaction between LDL-C levels and prestroke statin use regarding functional outcomes was investigated. Among the 4711 patients (age, 67 +/- 12 years; males, 62.1%) who met the eligibility criteria, compared with the high LDL-C group, the low and intermediate LDL-C groups were not associated with good outcomes at 3 months according to the multivariable analysis. A potential interaction between the LDL-C group and prestroke statin use on good outcomes at 3 months was observed (P-interaction = 0.07). Among patients with prestroke statin use, low (aOR 1.84 [1.04- 3.26]) and intermediate (aOR 2.31 [1.20-4.47]) LDL-C groups were independently associated with a greater likelihood of having a 3-month good outcome. Our study showed that LDL-C was not associated with a 3-month good outcome, but prestroke statin use could modify the influence of LDL-C levels on functional outcomes after IVT.N
