The effect of NaCl and Na(2)SO(4) salinity on NO(3) (-) assimilation in young barley (Hordeum vulgare L. var Numar) seedlings was studied. The induction of the NO(3) (-) transporter was affected very little; the major effect of the salts was on its activity. Both Cl(-) and SO(4) (2-) salts severely inhibited uptake of NO(3) (-). When compared on the basis of osmolality of the uptake solutions, ...

Stimulus-responsive molecular gel systems, based on metal salts of a luminescent gelator, 9,10-dioxooctadecanoic acid (DODA), are reported. These salts are structurally the simplest metallo-gelators of which we are aware that exhibit controllable mechano-responsive and luminescent properties. Aggregation is more favored by the metal salts than for DODA itself. However, gelation ability differs ...

1,1,3,3-Tetra(1H-tetrazol-5-yl)propane-based energetic salts were synthesized in a simple and straightforward manner. The structures of these new salts were determined by (1)H and (13)C NMR spectroscopy, IR spectroscopy, MS, and elemental analysis. All of these compounds showed good thermal stabilities above 180 °C, as confirmed by thermogravimetric-differential thermal analysis (TG-DTA) measur...

Lanthanides are a group of 15 chemical elements which, together with their salts, have come to be used in the last decade as homoeopathic remedies. The effective introduction of lanthanides and their salts into the clinical use, as homoeopathic remedies was based on the idea of Jan Scholten, MD to relate their physicochemical properties shown in the periodic table of elements to their homoeopat...

Aryl(alkynyl)iodonium salts have been demonstrated to be valuable precursors to a diverse range of heteroaromatic ring systems including aryl[1,2-a]imidazopyridines. Successful application, using the recently described aryl(alkynyl)iodonium trifluoroacetate salts, is described, highlighting for the first time that the regioselectivity of this process is both counter-ion and concentration depend...

The binding of conjugated bile salts to pancreatic colipase and lipase has been studied by equilibrium dialysis and gel filtration. The results indicate that at physiological ionic strength and pH, conjugated bile salts bind as micelles to colipase: 12-15 moles/mole of colipase for the dihydroxy conjugates and 2-4 for the trihydroxy conjugates. No binding of bile salt takes place from monomeric...

Benzalkonium salts are widely used as disinfectants, biocides and detergents,among a variety of other applications. The cationic surface-activity of these salts determines their potential to act as a biocide on both target and non-target organisms. In this study, a quick synthesis of a complete set of the benzalkonium salts differing in the length of an alkylating chain (from C(2) to C(20)) is ...

Chrysiasis is the phenomenon of bluish to slategray skin pigmentation induced by prolonged treatment with gold salts. The most common etiology is the administration of gold salts to patients with rheumatoid arthritis. Although parental gold salt administration is now uncommon because of the availability of biologic agents and disease-modifying antirheumatic drugs, chrysiasis may still be seen b...

Bile from patients with mixed gallstones and controls without gallstones was analysed for relative concentrations of bile salts, phospholipids and cholesterol. A significant difference was found in the concentration of bile salts in normal controls and patients with cholelithiasis. The mean values for total bile salts, phospholipids and cholesterol in patients' bile were Mean + S.E. 84.34 + 15....
