Cardiological research greatly rely on the use of cultured primary cardiomyocytes (CMs). The prime methodology to assess CM network electrophysiology is based on the use of extracellular recordings by substrate-integrated planar Micro-Electrode Arrays (MEAs). Whereas this methodology permits simultaneous, long-term monitoring of the CM electrical activity,(More)
Using cultured Aplysia neurons we recently reported on the development of a novel approach in which an extracellular, non-invasive multi-electrode-array system provides multisite, attenuated, intracellular recordings of subthreshold synaptic potentials, and action potentials (APs), the so called "IN-CELL" recording configuration (to differentiate it from(More)
PURPOSE To investigate the use of topical ocular anti-glaucoma medications by glaucomatous patients with obstructive pulmonary disease and their effect on related hospitalizations and emergency room visits. PARTICIPANTS We followed the electronic medical records of all the members in a district of the largest health maintenance organization in Israel (the(More)
Understanding how newly engineered micro- and nanoscale materials and systems that interact with cells impact cell physiology is crucial for the development and ultimate adoption of such technologies. Reports regarding the genotoxic impact of forces applied to cells in such systems that can both directly or indirectly damage DNA emphasize the need for(More)
Calcium ions are of key importance in a large number of cellular functions. In the past decade a large variety of cells have been found to show localized increases in the intracellular calcium concentration named calcium sparks. In this brief review, the methodology of detecting calcium sparks by confocal microscopy is summarized. Some of the properties of(More)
Bioinstrumentation engineers have long been creating platforms to study cell health and disease. It becomes necessary to ensure that such cell-probing tools do not themselves harm cells through complex stressors resulting from their design or operational conditions. Here, we present multiplexed cell-based sensors to simultaneously quantify stress induced by(More)
