in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

Clarithromycin (CLA), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. The aim of this investigation was to prepare CLA nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (SLS) and polyvinyl pyrrolidone (PVP) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. Different weight rati...

Background: The aim of this study was to develop a stable skin emulsifier from mupirocin. Materials and methods: This study was performed in the Department of Pharmacy, Tehran University of Pharmaceutical Sciences from November 2016 to September 2015. Initially, preformulation studies were performed on mupirocin powder and a standard diagram was drawn. Next, the bases of the drug-free emulsifi...

I. MOTIVATION Models of terrestrial legged locomotion are almost invariably hybrid, containing a discontinuity in the equations of motion when feet land on the ground. While some animals are bipedal, the great majority of legged locomotion on land is done with 4, 6 or more legs. Poly-pedal gaits for moderate or high-speed locomotion usually include multiple legs striking the ground that once (o...

The present work was aimed to develop and characterize rosuvastatin loaded self emulsifying drug delivery system for the effective management of hypolipidemia (RSEDDS) for improving bioavailability, to enhance solubility, to prolong residence time and to provide sufficient amount of drug to a target site in a sustained release manner. Self-emulsifying drug delivery system was prepared by simple...
