Swelling of hepatocytes and other epithelia activates volume-sensitive ion channels that facilitate fluid and electrolyte efflux to restore cell volume, but the responsible signaling pathways are incompletely defined. Previous work in model HTC rat hepatoma cells has indicated that swelling elicits ATP release, which stimulates P2 receptors and activates Cl(-) channels, and that this mechanism ...

in order to study on effect of magnetic field on germination characteristics and early growth of marigold (calendula officinalis l.) seeds an experiment was carried out in laboratory conditions in arak university of iran. seeds were magnetically exposed to magnetic field strengths, 100 or 200 mt for different periods of time; d1 (control), d2 (1 h), d3 (6 h), d4 (12h), d5 (24 h) and d6 (continu...

Groundwater resilience is defined and quantified with remote sensing from GRACETimescales of aquifer depletion are assessed as a Total Groundwater Stress ratioThe volume of usable global groundwater storage is found to be largely unknown.

Plasmonic nanoparticles influence the absorption and emission processes of nearby emitters due to local enhancements of the illuminating radiation and the photonic density of states. Here, we use the plasmon resonance of metal nanoparticles in order to enhance the stimulated depletion of excited molecules for super-resolved nanoscopy. We demonstrate stimulated emission depletion (STED) nanoscop...

agricultural activities have always been partly responsible for the emission of greenhouse gases and other environmental contaminants in the atmosphere. thus, studying on the environmental effects of agricultural activities and proposing appropriate strategies to mitigate these adverse effects can be paramount importance. in this study, in order to determine the environmental impacts of peanut ...

MDCK and JTC cells were subjected to ATP depletion by treating the cells with 10 microM antimycin A and 10 mM 2-deoxyglucose. As visualized by confocal fluorescence microscopy, E-cadherin and Na+,K(+)-ATPase were rapidly internalized following depletion of the intracellular ATP stores. The time course of internalization was similar to the depolymerization of the cortical actin network and disso...

this study aimed to evaluate the environmental consequences of kiwifruit production in guilan province of iran by the life cycle assessment (lca) methodology during growing season of 2011-2012. data were obtained from 84 kiwifruit producers using a face to face questionnaire method. for this purpose, a functional unit equal to one ton kiwifruit was assumed based on iso 14040 method. impacts of ...

BACKGROUND AND AIMS Fractal analysis allows calculation of fractal dimension, fractal abundance and lacunarity. Fractal analysis of plant roots has revealed correlations of fractal dimension with age, topology or genotypic variation, while fractal abundance has been associated with root length. Lacunarity is associated with heterogeneity of distribution, and has yet to be utilized in analysis o...

background: the dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...
