PURPOSE A spontaneously arising, apparently transformed, cell line has been cloned from a primary culture of human retinal pigment epithelial (RPE) cells and has been subcultured more than 200 times. The similarities of these cells to human RPE cells in vivo have been determined. METHODS The structure of the transformed cells has been determined by light(More)
The American College of Surgeons Committee on Trauma's Advanced Trauma Life Support Course is currently taught in 50 countries. The 8th edition has been revised following broad input by the International ATLS subcommittee. Graded levels of evidence were used to evaluate and approve changes to the course content. New materials related to principles of(More)
OBJECTIVES Historically, motor vehicle crash (MVC)-related mortality is higher in rural areas than in urban areas. The authors evaluated whether the difference in rural and urban MVC deaths is persisting, and whether the frequency of patients being found dead at the scene, particularly in rural areas, is increasing. METHODS Fatal Accident Reporting System(More)
In 2007, the Institute of Medicine's (IOM's) Committee on the Future of Emergency Care recommended that a multidisciplinary panel establish a model for developing evidence-based protocols for the treatment of emergency medical systems (EMS) patients. In response, the National EMS Advisory Council (NEMSAC) and the Federal Interagency Committee on EMS(More)
Retinal pigment epithelial cells, derived from human donor eyes, have been grown in culture as monolayers on membrane filters or plastic surfaces and shown to possess transferrin receptors with a monomeric molecular mass of 93,000. These receptors internalize 125I-labelled transferrin and recycle it to the surrounding medium in a similar manner to other(More)
PURPOSE Because retinal pigment epithelial cells in epiretinal membranes remodel and contract their surrounding extracellular matrix, investigations were performed to determine if these cells can produce matrix metalloproteinases and contract collagen gels in vitro in the presence of serum or cytokines. METHODS Cells were grown on collagen gels and their(More)
PURPOSE Integrins, heterodimeric cell surface glycoproteins, are involved in cell-substratum and cell-cell interactions. The role of these molecules in cytokine-mediated contraction of extracellular matrix by retinal pigment epithelial cells has been investigated in a model system that may mimic epiretinal membrane contraction during retinal detachment in(More)
Mass casualty triage is a critical skill. Although many systems exist to guide providers in making triage decisions, there is little scientific evidence available to demonstrate that any of the available systems have been validated. Furthermore, in the United States there is little consistency from one jurisdiction to the next in the application of mass(More)
Mass casualty triage is the process of prioritizing multiple victims when resources are not sufficient to treat everyone immediately. No national guideline for mass casualty triage exists in the United States. The lack of a national guideline has resulted in variability in triage processes, tags, and nomenclature. This variability has the potential to(More)
