Hepatocyte growth factor (scatter factor) is an angiogenic growth factor that binds to its cellular transmembrane receptor, c-met. Both HGF and c-met are expressed by vascular smooth muscle and endothelial cells, where HGF may exert autocrine and paracrine effects. We have found that human aortic smooth muscle cells (HASMCs) and human umbilical vein(More)
BACKGROUND Physician empathy is both theoretically and empirically critical to patient health, but research indicates that empathy declines throughout medical school and is lower than ideal among physicians. In this paper, we synthesize the published literature regarding interventions that were quantitatively evaluated to detect changes in empathy among(More)
Minorities are underenrolled in clinical research trials, and one-third of trials are underenrolled overall. The role of payment has not been studied at the national level as an explanation for enrollment patterns. Our objective was to examine the distribution of self-reported previous research participation across different sociodemographic groups; to(More)
The system considered in this paper is a mobile wireless network, commonly known as an ad hoc network. Mobile nodes in this dynamic topology function both as processors and routers to provide communication between nodes which are not within wireless transmission range. We present a token based mutual exclusion algorithm designed for an ad hoc distributed(More)
The problem addressed is the reconfiguration of a system of hexagonal metamorphic robots from an initial arbitrary shape configuration I, to a straight chain goal configuration, G. This is the first time a fully distributed deterministic algorithm has been written to achieve the parallel reconfiguration of a system of homogeneous modules from an initial(More)
This paper presents an algorithm that deterministically plans the simultaneous, collision-free movement of n hexagonal metamorphic robots (modules) over any contiguous surface composed of modules in a hexagonal grid. A planning stage algorithm identifies narrow passages between surface cells where moving modules will come into contact. After identifying all(More)
OBJECTIVE Timely, high quality communication with families is essential to family-centered decision-making. Quality communication is represented by widespread documentation of prognostic, goals-of-care conversations (PGOCC) in the pediatric intensive care unit (PICU) and should occur without variation by patient characteristics. METHODS Cohort included(More)
PURPOSE Physician participation in philanthropy is important to marshal resources that allow hospitals to pursue their missions, but little is known about how physicians participate and their attitudes toward participation. METHODS To characterize philanthropic roles physicians play and their attitudes about participation and its ethical acceptability,(More)
