Prediction of Acid Mine Drainage Generation Potential of A Copper Mine Tailings Using Gene Expression Programming-A Case Study

This work presents a quantitative predicting likely acid mine drainage (AMD) generation process throughout tailing particles resulting from the Sarcheshmeh copper mine in the south of Iran. Indeed, four predictive relationships for the remaining pyrite fraction, remaining chalcopyrite fraction, sulfate concentration, and pH have been suggested by applying the gene expression programming (GEP) a...

Physicochemical evaluation, study of stability and drug release kinetics from

Introduction: Acne is a disorder of the pilosebaceous unit of the skin and can present as non inflammatory and or inflammatory lesions. Tretinoin has been used therapeutically for over three decades. It is best known for its comedolytic effects on acne. It also inhibits comedone rupture, thus decreasing inflammatory events. Tretinoin is available in 0.01% to 0.1% as cream, gel or lotion. The ...

Bioactive secondary metabolites from acid mine waste extremophiles.

The extremophilic microbes of the Berkeley Pit Lake are a valuable source of new and interesting secondary metabolites. It is of particular interest that these acidophilic microbes produce small molecule inhibitors of pathways associated with low pH and high Eh. These same small molecules also inhibit molecular pathways induced by reactive oxygen species (ROS) and inflammation in mammalian cell...

Sustained Release of Green Tea Polyphenols from Liposomal Nanoparticles; Release Kinetics and Mathematical Modelling

Background: Green tea polyphenols (GTP) are known to have several health benefits. In spite of these benefits, its application as a therapeutic agent is limited due to some of its limitations such as stability, bioavailability, and biotransformation. To overcome these limitations, liposomal nanoparticles have been used as a carrier of the GTP. <spa...
