We identified a novel population of melanocyte-like cells (also known as cardiac melanocytes) in the hearts of mice and humans that contribute to atrial arrhythmia triggers in mice. To investigate the electrical and biological properties of cardiac melanocytes we developed a procedure to isolate them from mouse hearts that we derived from those designed to isolate neonatal murine cardiomyocytes...

The resource-based view is a theory of firm performance. Its principal argument is that a firm=s distinctive competencies are the bases for sustainable competitive advantage. These distinctive competencies are explicitly knowledge based resources. How do managers protect these rent generating assets--the skill sets and organizational routines of high value workers--from dissipation? Theory sugg...

Using double silent substitution, it is possible to generate L-cone and M-cone isolating electroretinograms (ERGs) on a CRT. A major limitation of the technique is that the depth of modulation of cone classes is limited by the restricted luminance of the phosphors and their spectral overlap. To address this problem we have ported the technique to a four-color LED Ganzfeld stimulus (Diagnosis Co...
