BACKGROUND The main barriers to non-viral gene delivery include cellular and nuclear membranes. As such, the aim of this study was to develop a type of vector that can target cells through receptor-mediated pathways and by using nuclear localization signal (NLS) to increase the nuclear uptake of genetic materials. METHODS A dexamethasone (Dexa)-conjugated lipid was synthesized as the material...

We examined the validity of percent body fat (%Fat) estimation by two-compartment (2-Comp) hydrostatic weighing (Siri 2-Comp), 3-Comp dual-energy X-ray absorptiometry (DEXA 3-Comp), 3-Comp hydrostatic weighing corrected for the total body water (Siri 3-Comp), and anthropometric methods in young and older individuals (n = 78). A 4-Comp model of body composition served as the criterion measure of...

Introduction The cyclic appropriate care program of the National Health Care Institute aims at enhancing quality in Netherlands. A full cycle consists four phases: (i) screening each ICD-10 chapter and selecting a trajectory, (ii) in-depth analysis trajectory formulating actions for improvement, (iii) implementation, (iv) evaluation. Collaboration with between relevant parties from field is key...

Tumor necrosis factor alpha (TNF alpha) stimulates granulocyte-macrophage colony-stimulating factor (GM-CSF) production in human fibroblasts and other mesenchymal cells. However, relatively little is known about agents that downregulate cytokine production in these cells. In the present report we show that dexamethasone (Dexa), a synthetic glucocorticoid, markedly reduced GM-CSF production in T...

Obesity is defined as an abnormal or excessive fat accumulation that may impair health. Dual-energy X-ray absorptiometry (DEXA) has been suggested as the gold standard to define obesity, but because its use is complex and expensive, anthropometric measures such as body mass index (BMI) or the waist-to-height ratio (WtHr) have been used as alternatives. The aim of this study was to review the pu...

BACKGROUND CONTEXT Osteoporosis and osteomalacia are significant risk factors for fracture and spine instrumentation failure. Low-energy fractures are becoming increasingly more common because of an increase in life expectancy and age of the population. Decreased bone density is an independent risk factor for instrumentation failure in spinal fusion operations. PURPOSE To assess the awareness...
