Zein-based nano/microparticles have been demonstrated to be promising carrier systems for both the food industry and biomedical applications. However, the fabrication of size-controlled zein particles has been a challenging issue. In this study, a modified anti-solvent precipitation method was developed, and the effects of various factors, such as mixing method, solvent/anti-solvent ratio, temp...

BACKGROUND The purpose of this study was to determine the impact of instructor feedback and video tutorials on skill acquisition during proficiency-based laparoscopic suturing training. METHODS Performance data from a prospectively maintained database were reviewed for three groups of novices (n = 34 medical students) who completed the same proficiency-based laparoscopic suturing curriculum o...

The "flipped classroom" is a learning model in which content attainment is shifted forward to outside of class, then followed by instructor-facilitated concept application activities in class. Current studies on the flipped model are limited. Our goal was to provide quantitative and controlled data about the effectiveness of this model. Using a quasi-experimental design, we compared an active n...

sex-linked mutant scute (sc), its noma1 allele, and a number of minor Tf:nes which can be shown to exist by selective breeding, form a developmental system which determines the number of bristles on the scutellum of Drosophila mlanogaster. In unselected stocks almost all flies grow four bristles when one or two + genes are present at the scute locus; that is, development is canalised at this le...

Introduction Supercontinuum (SC) has attracted considerable attentions due to its versatility in many fields such as telecommunication [1], optical metrology [2] and medical science. The SC phenomenon originates from the third-order nonlinearity of the media. In nonlinear optical fibers, both chromatic dispersion and nonlinear effects determine the SC generation characteristics. Different dispe...
