A novel dialysis adapter has been developed for USP apparatus 4 for in vitro release testing of dispersed system dosage forms. This USP apparatus 4 method was optimized and compared with currently used dialysis and reverse dialysis sac methods. Optimization studies for the USP apparatus 4 method showed that release from solution, suspension and liposome formulations was not flow rate limited an...

INTRODUCTION The aim of this in vitro study was to evaluate the amount of apically extruded bacteria associated with several root canal preparation systems. METHODS Forty-four extracted human mandibular premolar root canals were contaminated with an Enterococcus faecalis suspension. After incubation at 37°C for 24 hours, the root canals were instrumented using the Twisted File (SybronEndo, Or...

Corn and soyabean micronutrient-fortified-blended foods (FBF) are commonly used for food aid. Sorghum and cowpeas have been suggested as alternative commodities because they are drought tolerant, can be grown in many localities, and are not genetically modified. Change in formulation of blends may improve protein quality, vitamin A and Fe availability of FBF. The primary objective of this study...

We present the design and experimental analysis of a dielectrophoretic trap composed of four microfabricated gold posts excited in a quadrupolar fashion. Using quantitative modeling tools, we have designed these extruded traps to attain strong holding against flow while being constrained by a set of system parameters. The extruded geometry consists of cylindrical electrodes in a trapezoidal arr...

Seventy-two crossbred pigs weighing an average of 41.5 kg were assigned on the basis of sex, weight and litter to one of four dietary treatments in a factorial (4 treatments × 2 sexes) arrangement. The control diet was based on barley and soybean meal while the experimental treatments consisted of diets in which a portion of the dietary protein was supplied by 20% of a 50:50 blend of extruded (...

A case of an extruded cervical intervertebral disc at C7-D1 level with intradiscal hematoma in a 68-year-old male patient is presented. MR imaging showed a posterolateral extradural hemorrhagic lesion at C7-D1 level. It was suggestive of an epidural hematoma or a bleed within a neoplasm. A posterior approach was adopted and an extruded intervertebral disc with intradiscal hematoma was found and...

In the present study, 1.1 volume percent of nano size copper was incorporated into pure tin using hybrid microwave sintering assisted powder metallurgy route. Microwave sintered samples were extruded both at room temperature and at 230 °C. Microstructural characterization studies were conducted on the extruded samples to investigate the distribution characteristics of secondary phase and grain ...
