Purpose This study aimed to investigate the effect of initial soil pH and organic anion-to-acid ratio on changes in soil pH. Materials and methods Two soils (Podosol and Tenosol) along with two carboxylic acids (malic and citric acid) and their anions (sodium malate and citrate), commonly foun...
In order to gain insight into vacuolar changes that are associated with fruit specialization regarding the accumulation of organic acids, the properties of tonoplast vesicles extracted from grape cell culture and ripe berries were compared. The two primary pumps, PPase (Pyrophosphatase) and V-A...
The ring opening polymerisation of l,l-lactide using an equimolar complex of 2-ethylhexanoic acid tin(II) salt Sn(Oct)2 and triphenylphosphine P(φ)3 as catalyst shows for the first time a reactivity providing a polymerisation propagation rate fast enough to imagine a continuous single-step reac...
Groups of 10 male and 10 female Fischer 344 rats and B6C3F 1 mice were fed diets containing either 0.0, 0.1, 0.5 or 1.5% 2-ethylhexanoic acid (EHA) for 13 wk. Additional groups of 10 male and 10 female rats or mice, were fed either 0.0 or 1.5% EHA for 13 wk followed by a 4-wk recovery (...
In order to investigate the glucuronidation of 2-ethylhexanoic acid (2-EHA), a metabolite of the plasticizer di-(2-ethylhexyl)adipate, by liver microsomes of several mammalian species including man, a gas chromatography method for the quantification of the corresponding glucuronides was develope...
Success in biological and nanomaterial applications that rely on magnetic iron oxide nanoparticles (IONPs) often depends on monodispersity, size, and aqueous stability of the synthesized particles. Here we report a simple and efficient strategy to prepare monodisperse, ultrasmall, water dispersi...
Background/Objectives: Free radicals and reactive oxygen species (ROS), which are generated by UV irradiation, may induce an irreversible growth arrest similar to senescence. Tiron, 4,5‐dihydroxy‐1,3‐benzene disulfonic acid, is a widely used antioxidant to rescue ROS‐evoked cell death. The ...
While the involvement of environmental aluminum toxicity in the advent of senile dementias is still debated, acute aluminum toxicity of iatrogenic origin is well documented. So far, the only treatment available against it has been desferrioxamine (DFO), which induces major side effects. New dr...
Rongalite® promotes cleavage of disulfides generating thiolate anions that then undergo facile ring opening of epoxides in the presence of K2CO3 to afford α-addition products 3 with good to excellent yields. The important features of this methodology are broad substrates scope, high yielding, r...
In this work, starting from precursor films of Pb10O(OH)6(CO3)6, previously obtained by chemical bath deposition technique, we report the process to obtain PbSe films through ionic exchange. For this, after chemical deposition, several pieces of the precursor films were immersed in selenium ions...
Copper nanoparticles (Cu-Nps) are one of the promising material for the advancement of nanoscience and technology. In this work, we successfully synthesized Cu-Nps using sodium hydroxymethanesulinate (Rongalite) as a novel reducing agent via solution process. Cu-Nps were achieved from chemical r...
Enthalpies of dilution of aqueous solutions of 1-butanol, butanediols, 1,2,4-butanetriol and 1,2,3,4-butanetetrol (erythritol), were measured at 298.15K, using a LKB flow microcalorimeter. Experimental data were treated according to the McMillan–Mayer theory, to obtain the enthalpic interaction...
Isomeric polymers [Cd2(mbt)4] n and [Cd(mbt)2] n (mbt = mercaptobenzothiazole) are investigated. The complex {[Cd(μ-η2-C7H4NS2)2][Cd(μ-η2-C7H4NS2) (μ-η3-C7H4NS2)]} n is formed by the reaction of Cd(NO3)2·4H2O with 2-Hmbt in the presence of H2biim in EtOH/H2O. The complex crystallizes i...
A series of benzfused heterocyclic derivatives such as amide conjugates of 2-(benzo[d]thiazol-2-ylthio)acetic acid with aromatic/aliphatic/cyclic secondary amines (5a–5o & 8a–8m); 1,2,3-triazole conjugates of 2-mercaptobenzothiazoles and amide conjugates of indole-3-glyoxalic acid with cyclic ...
The effect of a heteroaromatic thiol and disulfide, viz. MBT and BTDS, was preliminarily studied in the photopolymerization of tetraethylene and triethylene glycol dimethacrylates (TETGDM, TEGDM), initiated with type I (Irgacure 369) and type II (camphorquinone, CQ) photoinitiators and benzoyl p...
Patulin (PAT) is a mycotoxin produced by several Penicillium, Aspergillus and Byssochlamys species. Since PAT is a potent genotoxic compound, and PAT contamination is common in fruits and fruit products, the search for newer, better agents for protection against genotoxicity of PAT is required. ...
Aims: Apples and apple products are the most notably commodities contaminated with patulin (PAT), which cause detrimental effects on human health and economic problems. The primary objective of this study was to investigate the removal of PAT contamination from apple juice using 10 different in...
Patulin (PAT), a present day major contaminant of commercial apple and apple products is reported to be carcinogenic, embryotoxic, and immunotoxic. While oral and inhalation are considered to be the most prevalent routes of exposure to this toxin, exposure through skin is now being extensively i...
Quantum mechanical (QM) calculations were carried out in order to study the host-guest inclusion complexes of procaine hydrochloride (Pro-H) and butacaine hydrochloride (But-H) with α- and β-cyclodextrins (α- and β-CDs) by PM3 and AM1 methods. The systems were studied by a 1:1 (α-CD/Pro-H, ...
Capillary electrophoresis method for identification and simultaneous determination of procaine, dihydrostreptomycin and penicillin G, present in multiantibiotic veterinary preparations, was elaborated. The influence of pH (5.0-9.75) and concentration of disodium tetraborate decahydrate in runnin...
