In this paper, we introduce a concept of a generalized $c$-distance in ordered cone $b$-metric spaces and, by using the concept, we prove some fixed point theorems in ordered cone $b$-metric spaces. Our results generalize the corresponding results obtained by Y. J. Cho, R. Saadati, Shenghua Wang (Y. J. Cho, R. Saadati, Shenghua Wang, Common fixed point  heorems on generalized distance in ordere...

The kinetics and thermodynamics of the pH-dependent multistate species generated by trans-chalcone n-pyridinebenzopyrylium (n = 2′, 3′) were studied UV–vis spectroscopy, 1H NMR HPLC-MS, results compared with those reported for n 4′. Due to slow interconversion, conjugation these techniques has shown be a powerful tool investigate behaviour systems. involved in are mutatis mutandis same observed...

The solid-state, low-temperature linkage isomerism in a series of five square planar group 10 phosphino nitro complexes have been investigated by a combination of photocrystallographic experiments, Raman spectroscopy and computer modelling. The factors influencing the reversible solid-state interconversion between the nitro and nitrito structural isomers have also been investigated, providing i...

ACETOACETIC and f-hydroxybutyric acids are known to undergo two chief metabolic changes, interconversion and oxidative breakdown. The reversibility of the reaction, acetoacetic acid =,-hydroxybutyric acid, was demonstrated in liver brei by Dakin & Wakeman [1910, 1, 2] and in perfused liver by Friedmann & Maase [1910]. Furthermore, the interconversion of these ketoand hydroxy-acids, both in live...

We previously reported that the all-cis isomer of arachidonic acid, the most naturally occurring isoform of this fatty acid, reduced cuprous copper ion-induced conversion of xanthine dehydrogenase into its reactive oxygen species generating form, xanthine oxidase. In the present study, the effects of all-trans isomer of arachidonic acid, in comparison with cis isomer of arachidonic acid, on the...

The spin-lattice relaxation times (Tl) of carbon 13 in natural abundance were determined for proline, N-acetylprolineamide, glycylproline, cyclo(triprolyl), and a series of proline-containing peptide hormones. The data are interpreted in terms of rapid interconversion of proline between various ring-puckered forms. The nature of the puckering depends upon the type of group attached to proline. ...

Glioma stem-like cells (GSCs) are undifferentiated cells that are considered to be an origin of glioblastomas. Furthermore, they may contribute to treatment resistance and recurrence in glioblastomas. GSCs differentiate into differentiated glioma cells (non-glioma stem-like cells: non‑GSCs), and interconversion might occur between GSCs and non-GSCs. We investigated whether interferon-beta (IFN-...

In the Southern Ocean, the nitrogen (N) isotopes of organic matter and the N and oxygen (O) isotopes of nitrate (NO3 ) have been used to investigate NO3 assimilation and N cycling in the summertime period of phytoplankton growth, both today and in the past. However, recent studies indicate the significance of processes in other seasons for producing the annual cycle of N isotope changes. This s...

Theoretical and experimental results are presented to illustrate the applicability of equilibrium rate measurements by isotope exchange to the understanding of the effect of modifiers on enzymic catalysis. A table summarizes the expected theoretical patterns for a two-substrate, two-product system with random substrate addition and ternary complex interconversion. Such patterns are used as a fi...
