The aim of the present study was to prepare, characterize and in-vitro evaluation of a Winsor-IV type microemulsion based drug delivery system incorporating celecoxib as BCS class–II model drug. Attempts were made to prepare cost effective O/W microemulsion using Tween 80, Glycerol, sunflower oil and water. The existence of microemulsion zone was investigated using phase diagrams. The systems w...

To historians and philosophers, Edinburgh is perhaps best known for being the centre of the Scottish Enlightenment. To its inhabitants, until recently, it was known as 'Auld Reekie', acknowledging its smoky atmosphere. Those of us who take an occupational history have heard the Scots words 'stour', for dust and 'reek', for smoke. Indeed, a friendly wish in Scots is 'Lang may your pipe reek'. We...

Strict positive realness (SPR) is an important concept in absolute stability theory, adaptive control, system identification, etc. This paper characterizes the strictly positive real (SPR) regions in coefficient space and presents a robust design method for SPR transfer functions. We first introduce the concepts of SPR regions and weak SPR regions and show that the SPR region associated with a ...

MOTIVATION Subtree prune and regraft (SPR) is one kind of tree rearrangements that has seen applications in solving several computational biology problems. The minimum number of rooted SPR ((r)SPR) operations needed to transform one rooted binary tree to another is called the (r)SPR distance between the two trees. Computing the (r)SPR distance has been actively studied in recent years. Currentl...

Substance P receptor (SPR), which plays a key role in pain transmission, is known to undergo rapid agonist-dependent desensitization and internalization. The present study shows that human SPR undergoes agonist-dependent phosphorylation in intact cells. Immunoprecipitation of SPR from 32Pi-labeled Chinese hamster ovary cells stably expressing human SPR (CHO-hSPR) indicates that substance P (SP)...
