Effect of copper on the adsorption of p-nitrophenol onto soils [PDF]

Environmental Pollution, 2006
The effect of copper on adsorption of p-nitrophenol on two typical Chinese soils was investigated using a batch-equilibration method. Adsorption experiments were carried out when both copper and p-nitrophenol were adsorbed simultaneously, and when copper was previously adsorbed on soils.

A Simulation Study of Inhibition Assay With Theophylline on the Enzymatic Hydrolysis of p‐Nitrophenyl Phosphate With Alkaline Phosphatase in a Continuous Mode of Electrophoretically Mediated Microanalysis

ELECTROPHORESIS, EarlyView.
Inhibition assays in in‐capillary continuous enzymatic reaction were simulated using a MATLAB matrix. The enzymatic hydrolysis of p‐nitrophenyl phosphate (S) with alkaline phosphatase (ALP) was adopted as a model enzymatic reaction, where theophylline (I) was used as a model inhibitor.

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Donkwa Enriched With Goron‐Tula (Azanza garckeana) Modulates Sexual Behavior and Activity of Enzymes Linked With Erectile Dysfunction in High‐Fat Diets/ Streptozotocin‐Induced (STZ/HFD) Diabetic Rats

Food Chemistry International, EarlyView.
(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values
