A simple, sensitive and specific stability indicating high performance liquid chromatographic (HPLC) method for the estimation of Desloratadine was developed and validated. Desloratadine was separated and quantitated on Inertsil ODS-3 V column (250 mm length, 4.6 mm id, 5 μm particle size) usin...
Analytical results are not complete unless they are expressed with their measurement uncertainty. Overall uncertainty may be control by controlling the most significant sources of uncertainty. The aim of this work was to establish a procedure to estimate measurement uncertainty of a validated UV...
We report the first multicomponent crystal of desloratadine, an important anti-histamine drug, with a pharmaceutically acceptable coformer of benzoic acid. The single crystal structure analysis revealed that this novel multicomponent crystal is categorized as salt due to the proton transfer from...
The lutetium diborate–dinitrate Lu2B2O5(NO3)2·2H2O was discovered through a hydrothermal synthesis from Lu(NO3)3·H2O and H3BO3. The compound crystallizes in the space group P1̅ (no. 2) with the lattice parameters a=789.52(5), b=988.62(6), c=1460.33(8) pm, α=90.83(1), β=101.75(1), and γ=110...
This work investigated the effect of dysprosium (Dy) ions on the structural, microstructural and magnetic properties of nickel nanospinelferrite, NiFe2O4. The nanoparticles (NPs) of NiDyxFe2–xO4 (0.0 ≤ x ≤ 0.1) were prepared via the hydrothermal method. The formation of cubic phase of Ni nano...
The separation of lanthanide (Ln(III)) elements from various waste materials is a significant issue facing developed countries. However, the chemical behaviour of Ln(III) are very similar and complex, and it is an important to understand clearly to optimize the separation processes under various...
Novel white light emitting dysprosium oxalate nanocrystals were prepared via microwave assisted co-precipitation method and the photoluminescence characteristics were elucidated on the basis of crystal structure. X-ray powder diffraction and transmission electron microscopy analyses were employe...
An efficient unprecedented Pd-catalyzed rapid 2-fluoroethoxylation of bromo-chalcones has been unveiled. The oxygen nucleophiles (fluoroalcohols) experience the rapid CO bond forming reaction for the first time, albeit the alcohols are known to be a weak nucleophile and have greater competing β...
A new series of Schiff and Mannich bases derivatives (6) of 4-[(4-amino-5-sulfanyl-4H-1,2,4-triazol-3-yl)methyl]-2H-1,4-benzothiazin-3(4H)-one (4), derived from (3-oxo-2,3-dihydro-4H-1,4-benzothiazin-4-yl)acetic acid (3) were synthesized. The structures of all newly synthesized compounds were el...
Gadolinium oxide (Gd2O3) nanoparticles with paramagnetic properties and biocompatible surfaces are promising materials for bioimaging applications. We synthesized in situ pegylated Gd2O3 (Gd2O3@PEG) nanoparticles by liquid phase pulsed laser ablation (PLAL) of a gadolinium target in a polyethyle...
In this work, an emulsion nanofluid membrane (ENM) was applied to effectively extract gadolinium. Simultaneous emulsification of nanoparticles and surfactant was performed to stabilize the ENM. Multi-walled carbon nanotubes (MWCNTs) nanofluid was employed as liquid membrane. The ENM composed of ...
Characterization of the compound formed in the reaction between the ligand di-n-butyldithiophosphoric acid (DBDTP) and gadolinium(III) ion, and a prediction of the possible molecular structure of the synthesized compound, using molecular modelling have been carried out. Ultraviolet spectra of th...
This work evaluates the performance of emulsion liquid membrane (ELM) for the extraction of gadolinium(III) from acidic solution. The ELM was made up of di-(2-ethylhexyl) phosphoric acid (D2EHPA) as carrier, Span 80 (sorbitol monooleate) as emulsifying agent, commercial kerosene as organic dilue...
Three new gadolinium(III) complexes of formula [Gd4(bta)3(H2O)16]n·12nH2O (1), [Gd4(bta)3(H2O)12]n·18nH2O (2) and [Gd2(H2bta)(bta)(H2O)2]n·4nH2O (3) (H4bta = 1,2,4,5-benzenetetracarboxylic acid) have been synthesized and their structures determined by X-ray diffraction. 1 and 3 are three-dime...
A simple and new procedure for the determination of trace amounts of lead(II), cobalt(II), manganese(II) and copper(II) is described, that combines atomic absorption spectrometry–gadolinium hydroxide coprecipitation. One milliliter of 1% gadolinium(III) solution was added to each sample; the pH...
This paper describes a method to fabricate gadolinium hydroxide (Gd(OH)3) nanoparticles. An opaque solution was prepared by adding basic anion exchange resin (BAER) to a Gd(NO3)3 aqueous solution at room temperature and aging the solution for 12–24 h; the solution became basic because of the ex...
Fibromyalgia (FM) is a chronic, painful, heterogeneous, and common disorder carrying a substantial socio-economical burden. It lacks effective cures and its aetiology is still unknown. There exists evidence for central and peripheral neurological contribution to the symptoms but grasping the rea...
Evidence indicates that a large portion of the facilitative glucose transporter isoform GLUT1 in certain animal cells is kept inactive and activated in response to acute metabolic stresses. A reversible interaction of a certain inhibitor molecule with GLUT1 protein has been implicated in this pr...
The effects of four chromatographically purified ionophore antibiotics (purity > 98.5% were studied on rumen fermentation using a semi-continuous system (Rusitec). The microbial population of the fermenters originated from the rumen of sheep fed a basal ration of hay without added antibiotic. Ea...
Four adult sheep fitted with rumen, simple duodenal and ileal cannulas, were continuously fed 980 g of a roughage-based diet supplemented (R2) or not (R1) with abierixin (22 ppm). Digesta flow at duodenum and ileum were measured using Yb as digestive marker. Cr-EDTA solution was infused to estim...
