We have developed a new methodology for forward analysis of retrogressive hydration (rehydration) reactions by an improved thermodynamic forward modeling technique based on a differential thermodynamic approach (Gibbs’ method). Based on natural observations and theoretical considerations, the progress of a rehydration reaction is modeled by incorporating a change in the effective bulk compositi...

The molecular geometry of complex of adenine with 8 water molecules was calculated with Hartree-Fock (HF). The standard 6-31G(d) basis set has been employed. The existence of C-H…O Hydrogen bonds between the water molecules and the hydrophobic part of nucleobase is stablished. We optimized structures and computed interaction energies of all complexes of adenine with water molecules step by step...

The application of stable isotopes in speleothem records requires an understanding of the extent to which speleothem calcite isotopic compositions refl ect the compositions of the cave waters from which they precipitate. To test for equilibrium precipitation, modern speleothem calcite was grown on glass plates, so that the carbon and oxygen isotope composition of the calcite and the water from ...

Continental flood basalts (CFB) are considered as potential CO2 storage sites because of their high reactivity and abundant divalent metal ions that can potentially trap carbon for geological timescales. Moreover, laterally extensive CFB are found in many place in the world within reasonable distances from major CO2 point emission sources.Based on the mineral and glass composition of the Columb...

Thermal behavior of the Shahreza dolomite ore is investigated in this paper. The hydration of the calcined dolomite was studied as a function of the calcination temperature. The DTA results exhibit three endothermic peaks at 800, 900 and 1050 °C, corresponding to decomposition of MgCO3 and CaCO3, both are present in dolomite and free calcite, respectively. The results also indicated that the de...

Aim. The efficacy of the short hydration regimen was reported in chemotherapy containing intermediate- to high-dose cisplatin, and the use of outpatient chemotherapy containing cisplatin with short hydration has been widespread in recent years. Methods. We compared patients with gastric cancer, lung cancer, and urothelial cancer who received outpatient chemotherapy containing cisplatin (≥60 mg/...

PURPOSE To assess the hydration status and level of hydration knowledge of youths at summer sports camps. METHODS Sixty-seven active youths, 57 males (mean +/- SD, 12 +/- 2 y, 136 +/- 16 cm, 50.6 +/- 21.1 kg) and 10 females (13 +/- 2 y, 153 +/- 8 cm, 45.2 +/- 9.0 kg) participated in 4 d of sports camp. Hydration status was assessed before the first practice (AM) and after the second practice ...

The Fox-1 RNA recognition motif (RRM) domain is an important member of the RRM protein family. We report a 1.8 Å X-ray structure of the free Fox-1 containing six distinct monomers. We use this and the nuclear magnetic resonance (NMR) structure of the Fox-1 protein/RNA complex for molecular dynamics (MD) analyses of the structured hydration. The individual monomers of the X-ray structure show di...

In this study, the achene mucilage content of six Turkish endemic Tripleurospermum taxa, namely T. baytopianum E. Hossain, conoclinium (Boiss. & Bal.) Hayek, fissurale (Sosn.) hygrophilum (Bornm.) Bornm., rosellum Orph.) Hayek var. album Hossain and ziganaense Inceer Hayirlioglu-Ayaz was determined by micro-staining reactions. Within examined cells on surface are capable forming a musil...

Contrast-induced nephropathy (CIN) is a complex syndrome of acute kidney injury that follows exposure to intravascular contrast media. Although a series of preventive measures have been developed, CIN remains a major challenge encountered in elderly patients by interventional cardiologists. No data are currently available concerning the potential effects of the combined use of hydration and alp...
