In this study, we developed and optimized a self-microemulsifying drug delivery system (SMEDDS) formulation for improving the dissolution and oral absorption of atorvastatin calcium (ATV), a poorly water-soluble drug. Solubility and emulsification tests were performed to select a suitable combination of oil, surfactant, and cosurfactant. A D-optimal mixture(More)
Bifidobacterium bifidum MIMBb75 is a recently identified probiotic. However, its distribution along the intestine and impact on resident microbiota is unknown. Herein, we established a quantitative real-time polymerase chain reaction assay targeting the B. bifidum-specific BopA region for the quantification of B. bifidum in feces and used this assay to(More)
A novel supersaturable self-emulsifying drug delivery system (S-SEDDS) was formulated to improve the oral absorption of dutasteride (DTS), a 5α-reductase inhibitor that is poorly water-soluble. A supersaturable system was prepared by employing Soluplus(®) (polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer) as a precipitation(More)
Calcium deposition may occur in walls of blood vessels and other conduits, within solid organs and tumors, and in the lumen of nearly every hollow structure. Occasionally, calculi seen in one radiograph may present in a different location on subsequent films. These “rolling stones” can make medical management difficult, and an understanding of the forces(More)
