OBJECTIVE To compare oxygen supply options for health facilities in the Gambia and develop a decision-making algorithm for choosing oxygen delivery systems in Africa and the rest of the developing world. METHODS Oxygen cylinders and concentrators were compared in terms of functionality and cost. Interviews with key informants using locally developed and adapted WHO instruments, operational as...
OBJECTIVES To analyze the trend of dextromethorphan abuse in California and to compare these findings with national trends. DESIGN A 6-year retrospective review. SETTING California Poison Control System (CPCS), American Association of Poison Control Centers (AAPCC), and Drug Abuse Warning Network (DAWN) databases from January 1, 1999, to December 31, 2004. PARTICIPANTS All dextromethorpha...
Concentrators are used to interface and combine together low speed communication channels onto higher speed transmission links to alleviate transmission costs. They are also used to construct more powerful switching fabrics such as permutation and broadcast networks. Using an adaptive binary sorting network model, this paper constructs new concentrators and superconcentrators. Unlike the previo...
Since their introduction in 1985, oxygen concentrators have only been recommended when domiciliary oxygen is used for over 8 h day-1. Subsequent changes in the prices of oxygen merit a reappraisal of the prescribing of concentrators and cylinders when oxygen is used for less than 8 h day-1. Twenty-six patients in two health districts who used oxygen for less than 8 h day-1 completed a crossover...
PROBLEM Hypoxaemia in children with severe or very severe pneumonia is a reliable predictor of mortality, yet oxygen was not available in most paediatric wards in Malawi. APPROACH The Child Lung Health Programme in Malawi made oxygen available by supplying oxygen concentrators and essential supplies to 22 district and 3 regional hospitals' paediatric wards. Five key steps were taken to introd...
Cardiovascular progenitor cells (CPCs) are a promising cell source for cardiac regenerative therapy because of their ability for self-renewal and differentiation into various cardiovascular cell types beneficial for myocardial repair: cardiomyocytes, smooth muscle cells, and endothelial cells. Previous evaluations of exogenously derived CPCs have focused mainly on their capacity for trilineage ...
Cardiovascular progenitor cells (CPCs) expressing the ISL1-LIM-homeodomain transcription factor contribute developmentally to cardiomyocytes in all 4 chambers of the heart. Here, we show that ISL1-CPCs can be applied to myocardial regeneration following injury. We used a rapid 3D methylcellulose approach to form murine and human ISL1-CPC spheroids that engrafted after myocardial infarction in m...
Transfer of cardiac progenitor cells (CPCs) improves cardiac function in heart failure patients. However, CPC function is reduced with age, limiting their regenerative potential. Aging is associated with numerous changes in cells including accumulation of mitochondrial DNA (mtDNA) mutations, but it is unknown how this impacts CPC function. Here, we demonstrate that acquisition of mtDNA mutation...
Title of Thesis: ON ROUTING AND PERFORMANCE EVALUATION OF BUFFERED SPARSE CROSSBAR CONCENTRATORS Degree candidate: Rahul Ratan Degree and year: Master of Science, 2002 Thesis directed by: Professor A. Yavuz Oruç Department of Electrical and Computer Engineering We investigate the routing and performance of sparse crossbar packet concentrators under a buffered network model. The concentration pr...
