Double-shelled Au/Ag hollow nanoboxes with precisely controlled interior nanogaps (1 to 16 nm) were synthesized for gap-tunable surface-enhanced Raman scattering (SERS). The double-shelled nanoboxes were prepared via a two-step galvanic replacement reaction approach using Ag nanocubes as the templates, while 4-aminothiolphenol (4-ATP) as SERS probe molecules were loaded between the two shells. ...

Background: In intensive care units, sepsis is a common diagnosis. Serum lactate rise has been established as an essential measure for predicting the outcome of sepsis. Higher anion gap(AG) associated with increased risk death in critically ill individuals. We measured blood levels and AG looked at how these predicted in-hospital outcomes (death or discharge).This st...

1-(2-Hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazole (metronidazole, MET) is a medication that is used to treat infections by a variety of anaerobic organisms, but there are relatively few reports of the structures of metal compounds that exhibit coordination of metronidazole. We have demonstrated that MET reacts with AgBF4 to give [Ag(MET)2]BF4·CH3OH, in which the Ag(I) cation is coordinated by...

Linear regression analyses identified a significant correlation of plasma D-lactate concentration with acidosis (bicarbonate, r ϭ Ϫ0.575, P Ͻ 0.001) and high anion gap (r ϭ 0.593, P Ͻ 0.001) (Fig. 1). The contribution of D-lactate to acidosis and anion gap was comparable to that of ␤-hydroxybutyrate. The contribution of D-lactate and ␤-hydroxybutyrate to the high anion gap found in DKA was stat...

The title compound, {[Pr(C(2)H(6)OS)(8)](2)[Mo(6)Ag(6)S(24)]}(n), contains polymeric Mo(6)S(24)Ag(6) (2-) anions and [Pr(Me(2)SO)(8)](3+) cations, forming a one-dimensional polymeric Mo/S/Ag cluster. The anion assumes the conformation of a zigzag chain. The trivalent cations are arrayed amongst the anionic chains and are well separated from each other. Each Mo and Ag atom is coordinated by four...

Background: With Stewart approach, pH depends on strong ion difference (SIDe), PaCO2 and non volatile weak acids (Atot). This approach might detect complex acid-base disorders undetected by conventional approach. We designed this study to describe acid-base disorders with both Stewart and conventional approaches and to compare the diagnostic performance in patients with chronic respiratory fail...

The title compound, {(C(13)H(22)N(4))[Ag(2)I(4)]}(n), was prepared by reaction of 1,3-bis-(N-ethyl-imidazolium-1-yl)propane iodide with silver (I) oxide. In the 3,3'-diethyl-1,1'-(propane-1,3-di-yl)di(1H-imidazol-3-ium) cation, the dihedral angle between the imidazole rings is 49.3 (1)°. In the [Ag(2)I(4)](2-) anion, each Ag(I) atom is bonded to three iodide anions, the two Ag(I) atoms and two ...

The serum anion gap, calculated from the electrolytes measured in the chemical laboratory, is defined as the sum of serum chloride and bicarbonate concentrations subtracted from the serum sodium concentration. This entity is used in the detection and analysis of acid-base disorders, assessment of quality control in the chemical laboratory, and detection of such disorders as multiple myeloma, br...

In the title compound, {(C(7)H(11)N(2))[Ag(2)(C(10)H(3)O(8))]}(n), the polymeric anion consists of two Ag(I) atoms and a Hbtc(3-) ligand (H(4)btc = benzene-1,2,4,5-tetra-carboxylic acid). Each Ag(I) atom is coordinated by four O atoms from three different Hbtc(3-) ligands. The two Ag(I) atoms are bridged by two bidentate carboxyl-ate groups into an Ag(2)O(4) cyclic unit, with an Ag⋯Ag distance ...

Previous studies have demonstrated that phenobarbital treatment impairs the biliary excretion of acetaminophen glucuronide (AG), although the transport system(s) responsible for AG excretion into bile has not been identified. Initial studies in rat canalicular liver plasma membrane vesicles indicated that AG uptake was stimulated modestly by ATP, but not by membrane potential, HCO(3)(-), or pH ...
