Disruption of the extensor mechanism as a result of patellar tendon or quadriceps tendon rupture is an uncommon but devastating complication after total knee arthroplasty. Treating a disrupted extensor mechanism can be challenging, particularly in patients who are morbidly obese, due to an increased risk of postoperative complications. Therefore, despite the debilitating nature of extensor mech...

The effective delivery of wraparound depends upon the availability of a wide range of community-based services. This study seeks to determine the impact of proximity to resources on the effectiveness of a wraparound program for stabilizing foster care placements among a sample of youth. We present a methodology for deriving proximity scores for individual clients using Geographic Information Sy...

Under increasingly stringent environmental regulations, inadequate green input levels from manufacturers may lead to substandard emissions and production shutdown, which further results in the disruption risk of supply chain. This work investigates a chain (GSC) consisting one environmentally regulated manufacturer capital-constrained retailer who faces stochastic market demand. The needs make ...

A rabbit model was used to compare the effect on the blood-brain barrier of the intracarotid injection of two new contrast media: iohexol, a nonionic monomer, and iodixanol, a nonionic dimer. It was hypothesized that the low osmolality of iodixanol (272 mOsm/kg at 300 mgl/ml) would cause less disruption of the blood-brain barrier than the relatively higher osmolality of iohexol (690 mOsm/kg at ...

There are many techniques to knock out directed genes in bacteria, some of which have been described in Salmonella species. In this study, a combination of SOEing PCR method and the λ Red disruption system were used to disrupt phoP gene in wild type and standard strains of Salmonella typhimurium. Three standards PCR and one fusion PCR reactions were performed to construct a linear DNA including...

*(Unfeasible is defined as autograft is no longer available because of prior use or insufficient tissue or the candidate is unacceptable because of any of the following reasons obesity, over 65 years of age, morbidity preventing harvesting at autograft donor site (infection, fracture), excessive risk of anatomic disruption from harvesting, osteoporosis, concurrent medical conditions and co-morb...
