Analysis of Implement-Criminal Policy Discourses to Control Drug Abuse

Objective: In this study, implement-criminal policy discourses to control drug abuse were analyzed. Method: The present research was descriptive-analytical and the data were collected in the form of a library research from books, dissertations and articles. Results: This study showed that due to the transfer of enforcement to various executive agents, the implement-criminal policy governing dru...

In Situ Cross-Linking of Polyanionic Polymers to Sustain the Drug Release from Theophylline Tablets

The aim of this study was to develop an extended-release tablet formulation using a new in situ cross-linking method. The effects of polyvalent cations on theophylline release from tablets made with the polyanionic polymers sodium alginate and sodium carboxymethylcellulose, were investigated. Different miliequivalents of the di and tri-valent cation, Ca2+ and Al3+, were added to tablet form...

Hyperhomocysteinemia: a million ways to lose control.

Elevated plasma levels of the amino acid homocysteine increase the risk for atherosclerosis, stroke, myocardial infarction, and possibly Alzheimer’s disease. In relation to vascular biology, many studies suggest that endothelial dysfunction contributes to the complex changes that occur within the vessel wall during hyperhomocysteinemia (HHCy). The underlying molecular mechanisms that are activa...
