SummaryWe demonstrated previously that exposure of rats to 2-butoxyethanol (BE) was associated with morphological changes in red blood cells, hemolytic anemia, and disseminated thrombosis and infarction in different organs including the eyes. In order to elucidate the mechanism of thrombosis for...

Elastic properties of three, isomorphous, orthorhombic (mm2) molecular-ionic crystals of sodium, potassium and rubidium acid phthalates have been studied employing the Brillouin scattering technique. The values of all elastic constants: stiffnesses cαβ and compliances sαβ were determined at ...

Bicarbonate reabsorption and NHE-3 expression: Abundance and activity are increased in Henle's loop of remnant rats.

One-molal solutions of potassium carbonate and potassium bicarbonate were investigated by Raman spectroscopy from 22° to 550°C and from 1000 to 2000 bar. Experiments were performed in a special hydrothermal pressure vessel fitted with conical diamond windows. Frequencies and half-widths of the...

N-acetyl-β-D-glucosaminidase (NAG) is one of the sensitive hydrolytic lysosomal enzymes which is released after renal tubular damages. We studied gentamicin-induced nephrotoxicity by determining the NAG release in perfused rat kidney. 100 μg/ml of gentamicin caused a time-dependent increase in...

Effects of chronic hyperfiltration on proximal tubule bicarbonate transport and cell electrolytes. The compensatory response to unilateral nephrectomy (UNX) was investigated by a combination of renal clearance, microperfusion, electron microprobe, and morphological techniques. Filtration rate wa...

Imogolite is an important paracrystalline hydrous aluminosilicate with a unique nanofiber structure. The synthetic imogolite sample was used for organofunctionalization process with 2-mercaptothiazoline and 2-mercaptobenzimidazole. Due to the increment of basic centers attached to the pendant ch...

The structural investigation of hydrated borate glasses provides new insights on the influence of water on boron speciation using spectroscopic methods. In the present study three soda–lime–borate glasses (NCBx with x = 5, 15 and 25 corresponding to xNa2O, 10CaO, 90 − xB2O3 in mol%) were prepa...

In situ spinel (MgAl2O4) generation in Al2O3–MgO refractory compositions at high temperature is pointed out as one of the most important reactions to improve their thermo-mechanical performance in service. However, this transformation effectively takes place above 1200 °C. Magnesium borates ar...

The Houxianyu borate deposit in northeastern China is one of the largest boron sources of China, hosted mainly in the Paleoproterozoic meta-volcanic and sedimentary rocks (known as the Liaohe Group) that are characterized by high boron concentrations. The borate ore-body has intimate spatial rel...

The Carbohydrate Esterase family 4 contains virulence factors which modify peptidoglycan and biofilm-related exopolysaccharides. Despite the importance of this family of enzymes, a potent mechanism-based inhibition strategy has yet to emerge. Based on the postulated tridentate binding mode of th...

The dissolution behavior of binary and ternary Na–Ca-borate glasses in phosphate-containing aqueous solutions was studied by micro-Raman spectroscopy. Raman spectra collected from the solutions provided information about the types and concentrations of borate anions released from the glass as a...

This work investigates the combined influence of borate and lithium ions on the hydration of two calcium sulfoaluminate (CSA) cements containing 0 or 10 wt% gypsum. On the one hand, borates are known to retard CSA cement hydration due to the rapid precipitation of ulexite. On the other hand, lit...

In the technological process of manufacturing, distribution and recycling of nanoparticles, is easy to spread them in the air. The respiratory system is the primary target for inhaled NPs. The authors discuss the influence of the complexing compounds used in the “button up” synthesis of inorga...

Calcium sulfoaluminate (CSA) cement is one of the potential candidates for the solidification of low and intermediate level radioactive nuclear waste which comprises high borate concentrations. Borate is well known for acting as set retarder during the immobilization of radioactive waste by ceme...

Stilbene analogues with the pyridine ring, that is di-(pyridin-2/3/4-yl)vinyl)benzenes, were synthesized, purified and completely spectroscopically characterized. Upon irradiation these di-(pyridin-3/4-yl)vinyl)benzenes showed no other process but isomerization, in conditions for both intra- and...

The molecular structure of a new complex of copper (II) with (E)-9-ethyl-3-(2-(6-(4-methylpyridin-2-yl)pyridin-3-yl)vinyl)-9H-carbazole ([Cu2(emppc)2Cl2]Cl2) was optimized with B3LYP/LanL2DZ, PBE1PBE/LanL2DZ and M062X/LanL2DZ theoretical level. The ligand, (E)-9-ethyl-3-(2-(6-(4-methylpyridin-2-...

The trace element composition of olivine is becoming increasingly important in petrological studies due to the ubiquity of olivine in the Earth's upper mantle and in primitive magmatic rocks. The LA-ICP-MS method allows for the routine analysis of trace elements in olivine to sub-ppm levels...

Olivine phenocrysts in basaltic rocks carry valuable mineral-chemical information on early evolution processes in mafic magmatic systems. Fast intra-crystalline diffusion and re-equilibration weakens this potential for major cation constituents of olivine, but the relative immobility of phosphor...

Shock-induced melting textures and assemblages in the chassignite Northwest Africa (NWA) 2737 were investigated. NWA 2737 consists mainly of coarse-grained olivine (Fa19.6–20.5) and minor amounts of low-Ca pyroxene, plagioclase (now maskelynite), and chromite. Several melt inclusions formed thr...
