A method is described for the study of transport processes in ghosts isolated from rat adipose cells. With this procedure it was possible to follow the time course of potassium uptake, potassium release, and sodium release. The uptake of potassium was stimulated by sodium and was inhibited by ouabain at concentrations down to at least 10e6 M. In the presence of pyruvate (1 mu), potassium uptake...

introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...

In the presence of aldosterone, plasma sodium in the high physiological range stiffens endothelial cells and reduces the release of nitric oxide. We now demonstrate effects of extracellular potassium on stiffness of individual cultured bovine aortic endothelial cells by using the tip of an atomic force microscope as a mechanical nanosensor. An acute increase of potassium in the physiological ra...

The physiological status of seven leatherback turtles (Dermochelys coriacea) was assessed at two time points during ecological research capture events in the northwestern Atlantic Ocean. Data were collected as soon as possible after securing each turtle onboard the capture vessel and again immediately prior to release. Measured parameters included sea surface temperature, body temperature, morp...

Potassium (K) is one of the essential macronutrients required for plants and its availability to hampered due fixation with other ions. The Releasing Micro-organisms (KRMs) present in soil are capable converting fixed form potassium into an available K uptake. Most commonly potash releasing bacteria rhizosphere belong phylum Firmicutes, Proteobacteria Actinobacteria. These microbes produce orga...

Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...
