the effect of phenylen di-isothiocyanate (jonit) in the mass treatment of various intestinal helminthiases was evaluated among the inhabitants of a village in dezful, southwest iran. stool samples collected and examined from 17 persons showed infection rates of 80% for ancylostoma duodenale, 57.3% for ascaris, 46.7% for trichostronylus spp. and 22.8% for h. nana.seventy- one persons (41 childre...

Deoxygenation of sickle cells is known to increase cation permeabilities (Na+, K+, and Ca2+). The possible mechanisms involved in the increased uptake of Ca2+ were investigated: activation of Ca2+ channels, involvement of the anion channel, and the formation of endocytic vacuoles. The Ca2+ channel blocker nifedipine reduced the deoxy-stimulated Ca2+ uptake by about 30% to 40%. The anion channel...

Immobilization of enzymes on mesoporous silicas (MS) allows for good reusability. MS with two-dimensional hexagonal pores in diameter up to 14.13 nm were synthesized using Pluronic P123 as template and 1,3,5-triisopropylbenzene as a swelling agent in acetate buffer. The surface of MS was modified by the silanization reagents 3-aminopropyltriethoxysilane. Lignin peroxidase (LiP) was successfully...

Ein Ethylenglykol-dekorierter [6]Cyclo-meta-phenylen(CMP)-Makrozyklus wurde hergestellt und als Untereinheit für den Aufbau eines vierfachen AuI2−Aryl-Metallazyklus mit einer quadratischen Überstruktur genutzt. Die Ecken bestehen aus dinuklearen Gold(I)-Komplexen, von denen bisher nur dreieckige Metallazyklen bekannt waren. Das Zusammenspiel flexibler Konformation des [6]CMP-Makrozyklus der sta...

The extensive pharmacological applications of the pyrazole-based compounds stimulated us to synthesize highly functionalized, pyrazolylmalonyl diisothiocyanate derivative (2) via treating 2-((1,3-diphenyl-1H-pyrazol-4-yl)methylene)malonyl dichloride (1) with ammonium thiocyanate in acetonitrile at room temperature. 2 was subsequently conducted a double molar ratio different nitrogen nucleophile...
