Ferrite nanoparticles (NPs) have gained attention in biomedicine due to their many potential applications, such as targeted drug delivery, their use as contrast agents for magnetic resonance imaging and oncological treatments. The information about the risk effects of ferrite NPs in human blood ...

Marine-derived nutrients are known accumulate in seabird breeding colonies due to the deposition of nutrient-rich biological materials, thus greatly altering the functioning and dynamics of these terrestrial ecosystems. Here we present the results of a sampling survey carried out during three ye...

The operational parameters and mechanism of mineralization of C.I. Reactive Yellow 84 (RY84), one of the azo dyes, in aqueous solution were investigated using sonolytic ozonation (US/O3 oxidation). Of the pseudo-first-order degradation rate constants of TOC reduction, 9.0 × 10−4, 7.3 × 10−3 an...

Carrageenan hydrogel as a “greener” and a vegetable-based stabilizing agent has the potential for many biosyntheses of different nanoparticles by sol-gel method. Herein, we describe for the first time an economic and eco-friendly preparation of cerium oxide nanoparticles (CeO2-NPs) using carra...

The concept of coping style represents the way individual animals react to a stressful situation, both behaviourally and neurophysiologically. Over the last decades coping style has been linked to the development of research on animal personality. Based on this concept, we should find a proactiv...

Ozonation is increasingly used for color fading dyed textile nowadays. This paper studied the overall effect of color fading ozonation on the color yield of cottons dyed by Reactive Blue FL-RN (RB-RN), Reactive Red FL-2BL (RB-2BL) and Reactive Yellow FL-2RN (RY-2RN) respectively. In which, the c...

Rivers play a vital role in geochemical processes of the critical zone. As the Third Pole, the geochemical processes of the Qinghai-Tibetan Plateau are vital to global element cycles. The Yellow River source region is located in the northeastern Qinghai-Tibetan Plateau, yet there has been little...

The effects of cassigarol A, a naturally occurring polyphenol, on gastric H+,K+-ATPase and gastric acid secretion were studied. Cassigarol A inhibited H+,K+-ATPase and K-stimulated p-nitrophenyl phosphatase from hog gastric mucosa with 50% inhibition of 1.2 × 10−6 and 6.3 × 10−6 M, respectivel...

The solvent extract of the outer green shell of the pistachio nut, Pistachia vera, was found to contain a mixture of phenolic acids. From their 1H and 13C NMR spectra and accurate mass measurement, their structures were established as 6-alkyl and cis 6-alkenylsalicylic acids. The approximate com...

The diene, (ZZ)-[(8,11)-pentadecadienyl]salicylic acid, (or 2-hydroxy-6-[(ZZ)-pentadeca-8,11-dienyl]benzoic acid), has been synthesised by two routes. In the first, the key intermediate methyl or ethyl 2-hydroxy-6-(7-bromoheptyl)benzoate has been converted to methyl or ethyl 2-hydroxy-6-(10-hydr...

The reaction between 4-oxo-2-alkenals (fumaraldehyde, 4-oxo-2-hexenal, and 4-oxo-2-nonenal) and phenolic compounds (resorcinol and 2-methylresorcinol) was studied to characterize the trapping ability of phenolic compounds for these lipid oxidation products. The reaction occurred rapidly under ne...

Racemic N-trifluoroacetyl pipecolic acid has been converted into (S)-N-Boc-pipecolic acid or (S)-N-Boc-2-piperidinemethanol by DCC/DMAP-induced diastereoselective esterification with (S)-α-methyl pantolactone, followed by a saponification or a reduction reaction and N-Boc protection.

In a previous series of potent GABA uptake inhibitors published from this laboratory, we noticed that asymmetry in the substitution pattern of the bis-aromatic moiety in known GABA uptake inhibitors such as 4 [1-(4,4-diphenyl-3-butenyl)-3-piperidinecarboxylic acid] and 5 [(R)-1-(4,4-bis(3-methyl...

IntroductionCarbon-11 (C-11) N,N-dimethyl-2-(2′-amino-4′-hydroxymethyl-phenylthio)benzylamine ([11C]HOMADAM) has been reported as highly specific and selective positron emission tomography (PET) radiotracer showing fast kinetics for the human brain serotonin transporter (SERT). In our continue...

A simple and rapid method to determine acesulfame-K and aspartame simultaneously in power sweeteners, without pretreatment was proposed. This method employs linear sweep voltammetry assisted with multivariate calibration tools, in order to resolve the overlapping signals of both analytes. Multiv...

Reaction of phenyl isocyanate and diethylaluminium alkoxide, Et2AlOR (R = Me, Et, i-Pr, t-Bu and benzyl) in equimolar or 3/1 molar ratios gave mainly diethylaluminium derivatives of N-phenyl carbamate esters, in contrast to the corresponding reactions with Et2AlNMe2 or Et2AlSEt. The diethylalumi...
