(PRA) and plasma concentration of arginin vasopressin (AVP) in this group. No responses to albumin infusion were noted in six of 15 patients (group B). These patients had high ANF and low PRA, suggesting a relative volume overload. It is well known that patients with liver cirrhosis do not represent a homogeneous group.5 There are at least two mechanisms leading to sodium and water retention an...

INTRODUCTION Although recently a matter of epidemiologic controversy, sodium overload and its interaction with genetic factors predispose to hypertension and related target organ complications. METHODS In 131 (66 male) treated hypertensives, we measured peripheral and central arterial pressures and pulse wave augmentation indexes (AIx(P), AIx(C1), AIx(C2)), pulse wave velocity (PWV), daily ur...

a new cesium ion selective pvc membrane based on parent calix [4] arene was developed for potentiometric determination of cesium in environmental samples. the electrode based on p-5,11,17,23tetra(tertbutyl) 25,26,27,28-tetrahydroxy calix[4]arene(thc) as ionophor ,dibutyl phthalate (dbp)as plasticizer ,sodium tetra phenyl borate(natpb)and oleic acid as lipophilic salt and additive showed the bes...

effects of sodium salt solutions on physicochemical and sensory characteristics of refrigerated persian sturgeon (acipenser persicus) fillets during 12 days of storage were investigated. fillets were dipped in solutions (2.5% w/v) of sodium acetate (sa), sodium lactate (sl), sodium citrate (sc) and distilled water (as control) for 10 minutes and then packaged. an assessment of tbars, ffa, ph, h...

Titrimetric estimation of calcium with disodium ethylene diamine tetra-acetate (E.D.T.A., sodium edetate), as performed on serum (Baron and Bell, 1957), cannot be applied directly to most other biological specimens because of their high concentration of phosphate. A high ratio of phosphate to calcium in the material titrated causes a drawnout and inaccurate endpoint. A rapid procedure for calci...

This study aimed to analyzing the effect of chronic sodium overload upon carotid and femoral injury, and its relation to vascular angiotensin modulation. Male C57Bl6 mice were divided in: control (cont), receiving 1% NaCl solution for 2 weeks (salt-2) or 12 weeks (salt-12). Two-weeks before the end of the study, a 2mm catheter was implanted around the left femoral and carotid arteries to induce...

The title compound, C9H10N4O, was obtained unintentionally by hydrolysis of 4-amino-1-benzyl-5-methyl-sulfanyl-1,2,4-triazolium tetra-fluoro-borate in the presence of sodium azide. In the crystal, alternating layers of polar amino-triazolinone and apolar benzene moieties are observed. N-H⋯O hydrogen bonds between the amino and carbonyl groups form infinite chains along [010]. These infinite cha...

The structure of triclinic disodium hafnium disilicate, Na2HfSi2O7, has been determined by laboratory powder X-ray diffraction and refined by the Rietveld refinement. The structure is a framework made of alternate layers of HfO6 octa-hedra and SiO4 tetra-hedra linked by common O atoms. Sodium atoms are located in the voids of the framework, aligned into tunnels along the [010] direction. Na2HfS...

In the title compound, [FePdCl(C5H5)(C8H11N)(C18H15Sb)], obtained by reaction of diphen-yl(N,N-di-methyl-amino-methyl-ferrocen-yl)stibine with sodium tetra-chlorido-palladate(II) in acetone, the Pd(II) atom is coordinated in a slightly distorted square-planar geometry by a C atom of the ferrocenyl ring, and by N, Cl and Sb atoms. The Sb and N atoms are trans to each other.

The title compound sodium dysprosium(III) bis-[tungs-tate(VI)], NaDy(WO(4))(2), has been synthesized under high temperature solution growth (HTSG) conditions in air. The compound crystallizes with the scheelite structure and is composed of isolated WO(4) tetra-hedra ( symmetry) with one set of bond lengths and distorted [(Na/Dy)O(8)] dodeca-hedra ( symmetry; occupancy ratio Na:Dy = 1:1) with tw...
