Infrared spectra of aqueous micellar solutions of sodium and potassium decanoates were measured as a function of external pressure up to and exceeding 50 kbar. Counterion interactions also generate an internal pressure in these micellar systems which strongly affects the features and shape of th...
Among the various side effects of supra-physiological dose of anabolic androgenic steroids that are described, renal toxicity remains the least evaluated. The present study provides evidence that long-term administration of nandrolone decanoate could lead to alterations of renal function and str...
Abuse of anabolic androgenic steroids is linked to a variety of cardiovascular complications. The aim of our study was to investigate the possible cardiovascular effects of nandrolone decanoate on young rabbits using echocardiography, histology and monitoring of telomerase activity, oxidative st...
The microcalorimetrically determined heat of dilution data are used to evaluate the enthalpy of micellization at the CMC (ΔHM) for potassium decanoate in H2O and D2O. The values for ΔHM based on a mass-action model are in good agreement with those determined graphically. That ΔHM in D2O is hi...
Haloperidol decanoate is a typical antipsychotic drug used as maintenance therapy for schizophrenia and mood disorders formulated as an ester for intramuscular injection. Cases of oral haloperidol decanoate intoxications have not been described in literature. In this report, we present for the f...
Synergistic extraction of zinc(II) with capric acid in the presence of pyridine was carried out at 25°C and at an aqueous ionic strength of 0.1 mol dm−3 (NaClO4), the total concentration of zinc, that of capric acid and that of pyridine being less than 4 × 10−3 mol dm−3, 0.15–1.5 mol dm−3 and...
Structure and transition behavior of zinc(II) stearate crystal were investigated by infrared and XAFS spectroscopies. Structure of zinc stearate at room temperature was estimated as follows. From XAFS analysis, the coordination number of the carboxylate groups around the zinc atom was evaluated ...
Partition of zinc and cadmium was carried out at 25°C in a system water and benzene containing capric acid in 0·1–2·0 M. Radiometry, flamephotometry and others have given evidence for the extractability of sodium caprate and its coextraction with the zinc family metals. Thus the following re...
A novel and multiple metal(loid)-resistant strain Comamonas testosteroni S44 with a high Zn2+ resistance level (10 mM) was isolated. To understand the molecular basis for the high zinc resistance, whole genome sequencing was performed and revealed a large number of genes encoding putative metal(...
A normal mode analysis was made for zinc caprate with using the Wilson GF matrix method. Based on the analysis and infrared spectra, structural transition behavior of zinc caprate was discussed.
Synchrotron radiation photoemission study of C 1s line of (111) In2O3 surface was carried out under HV (high vacuum) doses of oxygen, carbon monoxide and water. Gas interaction with the surface was activated by heating of In2O3 monocrystalline film at temperatures of 160 or 250 °C. The study of...
In a cw differential absorption experiment, we examined infrared transitions of excitons in Cu2O. We find a clear transition which is assigned to induced 1s para→2p para absorption. Line shape and intensity of induced absorption are analysed as a function of temperature and excitation conditions.
This work introduces molecular basis sets considering only 1s Slater orbitals and 1s Gaussian orbitals. The main purpose is the construction of a stable atomic model, to be useful for carrying out molecular calculations; among many possibilities, a tetrahedral structure is proposed. With these t...
We present the 1s X-ray photoemission spectrum of α-Fe2O3 in comparison with its 2p photoemission spectrum. We show that in case of transition metal oxides, because the 1s core hole is not affected by core hole spin-orbit coupling and almost not affected by core-valence multiplet effects, the F...
The C 1s peak's electron binding energy position in X-ray photoelectron spectroscopy (XPS) analysis of single crystal diamond (SCD) and crystalline and polycrystalline diamond and graphite films has been extensively investigated. A key issue is the experimental identification of C 1s peaks ...
The electronic structure of mineral tetrahedrite Cu12Sb4S13 showing a metal-semiconductor transition (MST) at TMST = 85 K has been investigated by means of Cu 1s x-ray absorption spectroscopy with the partial fluorescence yield mode (PFY-XAS) and Cu 2p-1s x-ray emission spectroscopy (XES). Remar...
Lactones are useful flavor compounds and some 5-hydroxy-γ-butyrolactones also have important biological activities. In this study, a newly isolated Bacillus strain 1s-1 was identified to be capable of producing 5-hydroxy-γ-decalactone (HDL) from peanut oil by gas chromatography–mass spectrome...
The O-polysaccharide (O-antigen, OPS) of Vibrio cholerae O68 was studied using chemical analyses and 1D and 2D NMR spectroscopy. The following structure of the tetrasaccharide repeating unit of the OPS was established:where Dhpa indicates (2S,4R)-2,4-dihydroxypentanoic acid existing mainly in th...
5-Deoxy-5-phospho-d-ribonohydroxamic acid, a mimic of the 1,2-cis-enediolate high-energy intermediate species of the allose-6-phosphate isomerase reaction, was obtained by a six-step synthesis from d-erythronolactone. In contrast to the known competitive ribose-5-phosphate isomerase (Rpi) inhibi...
The biological activities of deoxy sugars (deoxy monosaccharides) have remained largely unstudied until recently. We compared the growth inhibition by all 1-deoxyketohexoses using the animal model Caenorhabditis elegans. Among the eight stereoisomers, 1-deoxy-d-allulose (1d-d-Alu) showed particu...
