Elena Tchekneva, Mayme L. Lawrence, and Barbara Meyrick. Cell-specific differences in ET-1 system in adjacent layers of main pulmonary artery. A new source of ET-1. Am J Physiol Lung Cell Mol Physiol 278: L813–L821, 2000.— Endothelin-1 (ET-1) is a potent vasoconstrictor that causes sustained constriction of the pulmonary artery and modulates normal vascular tone. Endothelial cells were thought ...

Programmed current chronopotentiometry, specifically current reversal and current decrease, is applied to electrode reactions characterized by a chemical reaction coupled between two charge-transfer reactions, the ECE mechanism. The equations for the transition times are derived and solved. Current-reversal results on systems following the ECE mechanism, p-nitrosophenol, p-nitrophenol, and o-ni...

The idea of engineering cooling systems and generators based on thermal transformations and energy conversion in solids has been exciting scientific minds already for several decades. In recent years, a possibility of coolers production based on the electrocaloric effect (ECE) began to become of special interest [1]. This interest is related to the substantial progress made in investigations of...

Research suggests that approximately one third of threeand four-year-olds living in lowand middle-income countries are failing to meet basic benchmarks in cognitive or socialemotional development (McCoy et al., 2016). In response to this large need, stakeholders from multiple public and private sectors are increasingly investing in programs targeting children in the first years of their life (E...

Reliable and real-time information on soil and crop properties is important for the development of management practices in accordance with the requirements of a specific soil and crop within individual field units. This is particularly the case in salt-affected agricultural landscape where managing the spatial variability of soil salinity is essential to minimize salinization and maximize crop ...
