Adsorbents from sustainable precursors are highly desirable for practical applications. In this study, carboxymethyl cellulose (CMC) and humic acid (HA) were adopted to fabricate a composite immobilized on precipitates of calcium hydroxide (PCH) and ferric hydroxide (PFH). The as-obtained adsorb...

In this study, a pH-responsive hydrogel (cl-CMC-g-pHEA), based on carboxymethyl cellulose/2-hydroxyethyl acrylate, was prepared. Its physicochemical properties and applicability as a transdermal delivery system for naringenin (NRG) were investigated. The hydrogel was synthesized via radical poly...

D-lactic acid (D-LA) is gaining increased attention as it can improve the thermostability of poly lactic acid. Acid-tolerant Saccharomyces cerevisiae is a good host for D-LA fermentation. High catalytic efficiency of D-lactate dehydrogenase (D-LDH, EC 1.1.1.28) is crucial for the production of D...

[3H]5,8-Dihydroxypsoralen was effectively and selectively converted into 5,8-dimethoxypsoralen by roots of Ruta graveolens whereas [3H]8-methoxypsoralen and [3H]5-methoxypsoralen included for comparison were converted to a much lesser extent. These results indicate that 5,8-dihydroxypsoralen is ...

Coumarins are important constituents of Radix Angelicae Dahuricae, a well-known traditional Chinese medicine possess several known bioactivities with potentials in the treatment of central nervous system diseases. By using an HPLC–MS/MS method, we analyzed the in vivo plasma and brain pharmacok...

Cnidilin is one of the major bioactive constituents of Radix Angelicae dahuricae. The present study was designed to characterize and interpret the structures of metabolites in rats after oral administration of cnidilin at a dose of 48 mg/kg body weight. Metabolite identification was accomplished...

The reaction of 5-nitro-2,1-benzisothiazole-3-diazonium hydrogensulphate with anilines, N-alkylanilines and diphenylamine gives N-substituted 3-(4-aminophenyldiazenyl)-5-nitro-2,1-benzisothiazoles 2 and isomeric 1-(5-nitro-2,1-benzisothiazol-3-yl)-3-substituted-3-phenyltriazenes 1. The predomina...

A pair of isomeric heterocyclic compounds, namely 3-amino-5-nitro-[2,1]-benzisothiazole and 2-amino-6-nitrobenzothiazole, are used as the diazonium components to couple with two N-substituted 4-aminobenzene derivatives. As a result, two pairs of isomeric aromatic heterocyclic azo dyes have been ...

A study of the photodegradation of some 3-amino-5-nitro(2,1)-benziso-thiazole-based disperse dyes on polyester fabric is reported. A good correlation between the fading rate, measured from the changes of colour parameters (P%, L) as a function of irradiation time, and the electron-impact induced...

This paper is concerned with the application of alkoxy derivatives of some alkyl esters of N-benzyl-N-phenyl-β-alanine in the synthesis of heterocyclic azo dyes derived from 3-amino-5-nitro [2,1] benzisothiazole. The structure of the alkoxy intermediates was confirmed by IR and 1H-NMR. The dyes...

The synthesis of some disperse dyes from 3-amino-5-nitro[2,1]benzisothiazole and using as coupling components the alkyl esters of N-benzyl-N-phenyl -β-alanine containing different meta or para substituents in the benzyl ring is described. IR, 1H-NMR and visible spectra of the dyes are examined ...

This paper reports some kinetic measurements of the photofading in ethanol of some aminoazobenzene and related 3-amino-5-nitro(2,1)benzisothiazole-based disperse dyes derived from, as coupling components, derivatives of N-benzyl N-phenyl-β-alanine with different substituents in the benzyl or ph...

Human DNA topoisomerases represent one of the key targets of modern chemotherapy. An emerging group of catalytic inhibitors of human DNA topoisomerase IIα comprises a new paradigm directed to circumvent the known limitations of topoisomerase II poisons such as cardiotoxicity and induction of se...

The aim of this study was to design and synthesize COX-1/COX-2 balanced inhibitors incorporating the structural motifs of anti-inflammatory ascidian metabolites. We designed a series of substituted indole analogs that incorporate the key structures of the ascidian metabolites, herdmanines C and ...

The catalytic activity of benzoic acid could be increased by introducing a hydrogen bond donor group at the ortho-position. Preliminary DFT calculation indicated that the activation of CC double bond was realized by the action of both the carboxyl group and the hydrogen bond donor. The amino gro...

The engineering design and R&D of auxiliary heating systems and their sub-systems are a key activities in the frame of the present conceptual design phase for a first of a kind DEMOnstration Fusion Power Plant in order to develop a system capable of achieving and controlling burning plasmas. In ...

ITER will be equipped with four EC (Electron Cyclotron) Upper Launchers (UL) of 8 MW microwave power each with the aim to counteract plasma instabilities during operation. These launcher antennas will be installed into four upper ports of the ITER vacuum vessel. Beside their functional purpose t...

The control of the glycemic level among diabetes/T2 patients is very important for their long term survival and avoiding further complexities including micro/macrovascular diseases as well as diabetic neuropathy. Vildagliptin (VD) is a drug that has addressed these issues successfully with the d...

In the EC-driven (8.2 GHz) steady-state plasma on QUEST, plasma current seems to flow in the open magnetic surface in the outside of the closed magnetic surface in the low-field region according to plasma current fitting method without taking equilibrium into account. In our previous work, plasm...

A relevant issue in panel data estimation is heteroscedasticity, which often occurs when the sample is large and individual units are of varying size. Furthermore, many of the available panel data sets are unbalanced in nature, because of attrition or accretion, and micro-econometric models appl...
