Background: Cisplatin is an antineoplastic agent used to treat many malignancies; however, the main side effect of cisplatin is nephrotoxicity. The aim of this study was to evaluate the effect of hydration therapy with and without magnesium on prevention of cisplatin-induced nephrotoxicity. Methods: This retrospective study was performed on 46 patients with malignancy who were candidate to rec...

THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: (R,R)-2,4-bis-(4-hydroxy-phen-yl)-N,N'-dimethyl-3-oxapentane-1,5-diammonium bis-(hydrogen sulfate)], C(18)H(26)N(2)O(3) (2+)·2HSO(4) (-), contains one half-cation and one hydrogen sulfate anion. The cation has crystallographically imposed twofold symmetry with the rotation axis passing through the central ether O atom. Hydrogen bonds b...

BACKGROUND Neonatal nonoliguric hyperkalemia (NOHK) is a metabolic abnormality that occurs in extremely premature neonates at approximately 24 h after birth and is mainly due to the immature functioning of the sodium (Na+)/potassium (K+) pump. Magnesium sulfate is frequently used in obstetrical practice to prevent preterm labor and to treat preeclampsia; this medication can also cause hypermagn...

Natural dye extracted from Caesalpinia sappan Linn. was applied to a cotton fabric and silk yarn by dyeing process. The dyestuff component of Caesalpinia sappan Linn. was extracted using water and ethanol. Analytical studies such as UV–VIS spectrophotometry and gravimetric analysis were performed on the extracts. Brazilein, the major dyestuff component of Caesalpinia sappan Linn. was confirmed ...

The discovery of hydrogen-rich waters preserved below the Earth's surface in Precambrian rocks worldwide expands our understanding of the habitability of the terrestrial subsurface. Many deep microbial ecosystems in these waters survive by coupling hydrogen oxidation to sulfate reduction. Hydrogen originates from water-rock reactions including serpentinization and radiolytic decomposition of wa...

Ionic liquids based on 1-alkyl-3-methylimidazolium cations and the hydrogen sulfate (or bisulfate) anion, HSO(4)(-), are much more viscous than ionic liquids with alkyl sulfates, RSO(4)(-). The structural origin of the high viscosity of HSO(4)(-) ionic liquids is unraveled from detailed comparison of the anion Raman bands in 1-ethyl-3-methylimidazolium hydrogen sulfate and 1-butyl-3-methylimida...

The cations and anions of the title salt, 3C(6)H(16)N(+)·HSO(4) (-)·SO(4) (2-), are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. The hydrogensulfate ion, with a single S-O(H) bond of 1.563 (2) Å, forms a short O-H⋯O hydrogen bond [O⋯O = 2.609 (2) Å] to the sulfate ion. The hydrogensulfate ion accepts two hydrogen bonds from two cations, whereas the sulfate ion, as ...

In this study, oxidation of some 3,5-diacyl or 3,5-diester 1,4-dihydropyridines to corresponding pyridine derivatives using sodium bromate in the presence of NH4Cl, NaHSO4 and Bu4NHSO4 under thermal conditions has been investigated. The yield and structure of formed products is similar under all conditions; however, the reaction is accelerated in the presence of Bu4NHSO4 and NaHSO4. In addition...
