The present paper investigates a detailed study on the optical properties of PVA/Ag nanocomposite films. In this interest , PVA/Ag nanocomposites with different ways of study ,the first prepared film by reduction 0.2M of Ag+ ions in 2 gm of PVA and study the transmission , absorption coefficient, refractive index, extinction coefficient, reflection, real & imaginary part of the dielectric const...

The dinuclear title complex, [Ag2(C6H7N2S)2(C18H15P)2], comprises two inversion-related [Ag(C6H7N2S)(C18H15P)] units. The pyrimidine-thiol-ate anion acts both as a bridging and a chelating ligand. The Ag(I) ions are linked via two μ2-S donor atoms, which generate a strictly planar Ag2S2 core with an Ag⋯Ag separation of 2.9569 (4) Å. The Ag(I) ion presents a distorted tetra-hedral coordination g...

The asymmetric unit of the title compound, (C(14)H(20)N(4))[Ag(CN)(2)](2), contains one-half of a centrosymmetric 2,2'-(p-phenyl-ene)bis-(1,4,5,6-tetra-hydro-pyrimidinium) (H(2)btb) cation and one [Ag(CN)(2)](-) anion. In the anions, the Ag(I) atoms adopt near linear coordination modes with the two attached cyanide groups [C-Ag-C = 173.3 (2)°]. In the crystal structure, each H(2)btb cation link...

In the title compound, {[Ag(C(12)H(11)N(3)O)]NO(3)·H(2)O}(n), the Ag atom is coordinated by two N atoms from the heterocyclic ligand, giving a linear polycationic chain. Two long Ag⋯O(nitrate) inter-actions [2.667 (3) and 2.840 (3) Å] result in a three-dimensional network. The water mol-ecule consolidates the network structure by forming hydrogen bonds, one to the polycationic chain and one to ...

Because the anion gap is useful in classifying acid-base disorders, quantitative information on this variable should be readily available. Three populations were studied and means and central 90% ranges were determined for the anion gap, calculated as sodium-(chloride + bicarbonate). In 1047 hospitalized patients the mean was 12 mEq/liter, 86 faster volunteers had a mean of 13 mEq/liter with a ...

Renal tubular acidosis (RTA) is a non-uremic defects of urinary acidification. It is characterized by a normal anion gap hyperchloremic metabolic acidosis; plasma potassium may be normal, low or highdepending on the type of RTA. These syndromes differ from uremic acidosis which is associated with a high anion gap, decreased glomerular filtration with enhanced proton secretion by the remaining n...

BackgroundAlthough previous studies have reported that many biomarkers can determine the prognosis of patients with acute myocardial infarction (AMI), serum anion gap (AG) has not been well studied. We aimed to investigate association between AG and mortality in AMI.MethodsAdult first admitted ICU diagnosed AMI from 2008 2019 MIMIC-IV database were included. Patients divided into survival non-s...

The reaction of 2-acetylpyridine with silver(I) tetra-fluorido-borate leads to the discrete title complex, [Ag(C(7)H(7)NO)(2)]BF(4), in the cation of which the Ag atom is coordinated by two 2-acetylpyridine ligands, each of which is N,O-bidentate, albeit with stronger bonding to the N atoms [Ag-N = 2.2018 (15) and 2.2088 (14) Å; Ag-O = 2.5380 (13) and 2.5454 (13) Å]. The four-coordinate Ag atom...

Organic anion template-controlled reactions of benzenepolycarboxylic acids with silver(I) salts resulted in two coordination polymers with distinct structural features based on the argentophilic interaction, one exhibiting a honeycomb layer formed by the fusion of macrocyclic Ag(16) rings and the other furnishing the first example of a Ag(∞) tubular motif.

BACKGROUND In vitro data suggest that lower extracellular pH activates the immune system. We conducted a population-based study of the relation between serum acid-base status and inflammation. METHODS We examined the serum anion gap and serum levels of bicarbonate and inflammatory biomarkers in 4525 healthy adults who participated in the National Health and Nutrition Examination Survey during...
