Cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CMs) offer a new means to study and understand the human cardiac action potential, and can give key insight into how compounds may interact with important molecular pathways to destabilize the electrical function of the heart. Important features of the action potential can be readily measured using standard experimental techniques, such as the use of voltage sensitive dyes and fluorescent genetic reporters to estimate transmembrane potentials and cytosolic calcium concentrations. Using previously introduced computational procedures, such measurements can be used to estimate the current density of major ion channels present in hiPSC-CMs, and how compounds may alter their behavior. However, due to the limitations of optical recordings, resolving the sodium current remains difficult from these data. Here we show that if these optical measurements
There is undoubtedly a consensus within the international community that ‘vaccine nationalism’ is an undesirable state of affairs. However, states are self-interested actors and in the absence of constraints imposed by international economic law this pursuit of rational self-interest is likely to result in an outcome that is unjust on a global scale. The recent proposal by India and South Africa to suspend TRIPS obligations for the duration of the COVID-19 pandemic has been rejected within the WTO. This proposal constitutes a recognition of the inadequacies surrounding the TRIPS compulsory licensing scheme. Yet, the immersion of intellectual property law within international investment law together with the proliferation of free trade agreements containing TRIPS-plus obligations would likely have made such a proposal unworkable. We argue that the fundamental problem is that the TRIPS Agreement lacks a defined concept of conscience that governs both its operation and interpretation. Such a principle exists in the common law within the field of private law. The principle, in its various doctrinal iterations, navigates the tensions between different parties while serving an underlying purpose of justice within the common law. It has much to offer international intellectual property law.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
