TL;DR: Bioprosthetic glutaraldehyde-treated mitral valves can be implanted into the mitral position in pigs and function after 6 months and were comparable to results obtained in sheep models and human demonstrating the suitability of the porcine model.

TL;DR: Changes in the DPTI/SPTI ratio showed that the improvement in left ventricular performance was at the expense of myocardial oxygen balance, which caused a greater incidence ofMyocardial underperfusion, particularly in patients with cardiac failure.

TL;DR: This paper argued that the differences of operating in one's home country versus abroad are the major difficulties faced by foreign firms, and subsequently the differences between foreign countries are only marginal, and argued that international expansion is a discontinuous process characterized by an initial "big step" and no relationship between time to expansion and the cultural distance of the target country will exist.

TL;DR: In this paper, the authors review the debate and offer new perspectives on how to extend existing theories by accounting for four specific aspects of the home country institutional environments of emerging economies: breadth, depth, timing, and duration of exposure to institutional development.

TL;DR: In this article, a number of concrete suggestions for areas in which international business research may benefit from Levinthal's work and vice versa are provided, as well as some concrete examples of areas where the IB field could benefit from his work.
