The aim of present study is simultaneous and individual removal of chromium (VI) (Cr(VI)) and fluoride (F) ions with activated carbon (AC) electrode by capacitive deionization (CDI). Capacitive deionization is recently developing and worldwide attracted technique due to less energy consumption a...

Nucleation and growth mechanisms of trivalent chromium conversion coatings on 2024 aluminium alloy (AA 2024) were studied. Nucleation of 25 nm diameter nodules was observed on the ridges of the scalloped structure of degreased and desmutted AA 2024 after very short time of conversion treatment c...

A comparative study of nuclear magnetic resonance and UV–visible spectroscopy of dose-response for polymer gel dosimeters was performed. Dosimeters were prepared using N-(Isobutoxymethyl) acrylamide (NIBMA) as a new monomer via radiation induced polymerization for use in radiotherapy planning. ...

N-(Isobutoxymethyl) acrylamide (NIBMA) monomer in gelatin, named NIBMAGAT gel dosimeter, was prepared and investigated by nuclear magnetic imaging (NMR) for radiotherapy in the dose range of 0–30 Gy. NIBMA monomer polymerizes upon irradiation, increasing spin–spin relaxation rate R2. The addit...

Normoxic N-(isobutoxymethyl)acrylamide polymer gel (NIBMAGAT) dosimeters have been prepared in deionized water with acetone as a co-solvent for radiotherapy with very low levels of turbidity. The polymer gel dosimeters were irradiated in a cubic water phantom using a 6 MV X-ray radiation beam of...

Competition between sigma-participation by C$$$-Cγ and pi-resonance by ∝-aryl group could be illustrated from the decreasing of (Z)/(E) rate ratios with increasing electron releasing of aryl substituent in the solvolysis of titled substrates. Product studies gave rise to the question about the...

Electrolysis of Guareschi imides in alcohol in an undivided cell in the presence of sodium bromide as mediator results in fast and efficient cyclization with formation of a substituted 3-azabicyclo[3.1.0]hexane system in 80–98%. The fast (30 min) electrocatalytic reaction proceeds smoothly unde...

The preparation and some properties are described of two sugar derivatives containing a new functional group, namely hydroxythio(thiocarbonate) [ROC(=S)-SOH]. These derivatives were prepared by reaction of hydrogen peroxide with the O-(sodium thiolthiocarbonyl) derivative of 1,2:3,4-di-O-isoprop...

The experimental and theoretical vibrational spectra of S-S-2 methylamino-1-phenyl propan-1-ol (SSMPL). Fourier transform infrared (FTIR) and FT Raman spectra of SSMPL in the solid phase were recorded and analyzed. The molecular geometry, vibrational frequencies, infrared intensities, Raman acti...

SummaryA well documented study on the anticonvulsant properties of 4-amino-N-(2-ethylphenyl)benzamide (4-AEPB) is here provided. Initial screening in mice dosed intraperitoneally and rats dosed orally indicated that 4-AEPB is active against maximal electroshock—induced seizures (MES), but does ...

Oxidative stress is thought to play a key role both in the neurotoxin MPTP- and manganese (Mn)-induced neurotoxicity and in apoptotic cell death. In the present study, we report that Mn and the MPTP analogue 1-methyl-4-(2′-ethylphenyl)-1,2,3,6-tetrahydropyridine (2′Et-MPTP), which is metaboliz...

The electronic absorption spectra of 4-((2-ethylphenyl)diazenyl)benzene-1,3-diol and 2-((2-ethylphenyl)diazenyl)benzene-1,3,5-triol molecules in the nine different solvent variable electronic characters have been recorded. The solvent dependent maximum absorption band (π–π* transitions) shift...

Single crystal of (E)-1-(4-ethylphenyl)-3-(4-(heptyloxy)phenyl)prop-2-en-1-one (4EPC) was grown in acetonitrile via slow evaporation solution technique. The molecular structure of 4EPC was then confirmed by single crystal X-ray diffraction analysis and the crystal exhibited monoclinic with centr...

The hydrophilic ion paring strategy (HIP) is a method explored to improve the cell/tissue uptake of poorly adsorbed drugs and to optimize their physico-chemical characteristics. In this context, we here describe the synthesis of some ion pairs of two model cationic antibiotics, erythromycin (ERY...

The combined effects of erythromycin–tetracycline–sulfamethoxazole (ETS) and sulfamethoxazole–tetracycline (ST) antibiotics on the performance of anaerobic sequencing batch reactors were studied. A control reactor was fed with wastewater that was free of antibiotics, while two additional reac...

Studies have demonstrated that several chemicals are absorbed and metabolized during skin permeation. We investigated the absorption and metabolism of the pesticide butachlor. Radiolabeled butachior was measured in human (n = 5) skin and the unchanged compound and metabolites were quantified by ...

Insulin degrading enzyme (IDE) is a zinc metalloprotease that degrades small amyloid peptides such as amyloid-â and insulin. So far the dearth of IDE-specific pharmacological inhibitors impacts the understanding of its role in the physiopathology of Alzheimer's disease, amyloid-â clearance,...

In this manuscript, the synthesis and biological activity of a series of pyrazole acetic acid derivatives as CRTh2 antagonists is presented. Biological evaluation in vitro revealed that the pyrazole core showed in several cases a different structure–activity relationship (SAR) to that of relate...

A series of 3- and 4-(sulfo- and sulfonamidoalkyl)pyridine and piperidine-2-carboxylic acid derivatives as analogs of NMDA receptor antagonists was prepared. Affinity for the NMDA receptor was determined by binding assays using the specific radioligand [3H] (2SR,4RS)-4-(phosphonomethyl)piperidin...

Steroid 5α‐reductase (5αR) inhibitory potency of three N‐(dicyclohexyl)acetyl‐piperidine‐4‐(benzylidene‐4‐carboxylic acids) and their corresponding methyl esters was monitored for type 2 isoenzyme in a benign prostatic hyperplasia cell free preparation and for type 1 isoenzyme in DU145 ...
