High-resolution solid state 13C, 23Na and 31P NM R data have been obtained for the acid form and for several salts o f the phosphonic acids: ethane-1 ,2 -diphosphonic acid, ethane-l-hydroxy1.1-diphosphonic acid (H E D P ), and 3-am ino-l-hydroxypropane-l,l-diphosphonic acid. The data provide evidence by which sample purity and crystallinity may be examined and from which the size of the asymmet...

The administration of adrenal steroids to animals and human subjects on diets containing sodium but little or no potassium is followed by alterations in cellular composition characterized by a loss of potassium which is partially replaced by sodium and the supervention in the extracellular fluid of a metabolic alkalosis.' The experiments have been performed principally in rats where the sodium ...

ETHNOPHARMACOLOGICAL RELEVANCE This article presents the results of an anthropological and ethnobotanical study of the vegetable salts used by the Witoto Indians of the Amazon. It thoroughly documents the species used, the processing of the salts, their chemical composition and their anthropological, nutritional and medicinal relevance. MATERIALS AND METHODS Salts from 57 plant species known ...

ABSTRACT Saturated salt solutions produce environments with specific relative humidities used in several applications, such as determining water sorption isotherms of foods. However, the preparation saturated requires knowledge solubility data. Thus, objective this work was to determine 14 salts: lithium bromide (LiBr), chloride (LiCl), iodide (LiI), magnesium (MgCl2), sodium (NaI), potassium c...

debaryomyces hansenizopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by ulocladium. chartarum(pr.) simm. the ability of d. hansenii to prevent infection of u. chartarum was lost when the antagonist cells were killed by autoclaving. cell free culture filtrates of antagonist were unable to prevent disease incidence. efficacy ...

nitrate is one of the major sources of nitrogen for the growth of plants. it is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. the main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mrna in triticum aestivum plants. the pl...

The byproducts of flue gas desulfurization (BFGD) are a useful external source of Ca(2+) for the reclamation of sodic soils because they are comparatively cheap, generally available and have high gypsum content. The ion solution composition of sodic soils also plays an important role in the reclamation process. The effect of BFGD on the soluble salts composition and chemical properties of sodic...

Cellobiose lipids (CLs) are asymmetric bolaform biosurfactants, which are produced by Cryptococcus humicola JCM 10251 and have fungicidal activity. In this study, the sodium salts of CLs (CLNa) were prepared to improve aqueous solubility of the CLs, and their surface and gelation properties in aqueous solutions were examined by surface tension, rheology, and freeze-fracture transmission electro...
