immediate early step in PrE specification. We show that the fraction cells present with in this state is influenced by factors that both promote and suppress primitive PrE differentiation, however conditions that support ES cell self-renewal prevent their progression into endoderm differentiation and support an equilibrium between this state and at least one other that resembles the inner cell ...

In order to provide realistic haptic feedback, simulators must incorporate accurate computational models of the in-vivo mechanical behavior of soft tissues. Surgical simulation technology has progressed rapidly but lacks a comprehensive database of soft tissue mechanical properties with which to incorporate. Simulators are often designed purely based on what "feels about right;" quantitative em...

Fluid phospholipid bilayers partially bound to a supporting polymer cushion (tethered supported membranes) have been widely discussed as model systems for studying biomembrane structure and function. We have synthesized a new isothiocyanate-functionalized lipid from dimyristoylphosphatidylethanolamine, which closely resembles naturally occurring membrane lipids. Monolayers containing the reacti...

Controlled remodeling of the extracellular matrix (ECM) is essential for cell growth, invasion and metastasis. Matrix metalloproteinases (MMPs) are a family of secreted, zincdependent endopeptidases capable of degradation of ECM components. The expression and activity of MMPs in a variety of human cancers have been intensively studied. They play important roles at different steps of malignant t...

Background Computational cardiac modelling has been established as a valuable tool for simulating electrophysiology and electromechanics of the heart [1], with promising applications to “personalized medicine” [1]. Realistic computational models require a detailed description of left-ventricular cardiac fiber architecture. So far, nonpatient-specific fiber architectures have been obtained from ...
