Human extracellular superoxide dismutase(hEC-SOD) is a secreted tetrameric protein involved in the protection of a human body from oxygen free radicals. Its thr
Some new derivatives of 3-ethoxycarbonyl-6-bromo-5-hydroxyindoles were designed and prepared, their antiviral activity were determined in cell culture with viru
Four geometric mer-isomers in the [Co(2,3-tri)(cmen)Cl]2+ system have been synthesized and well separated (2,3-tri = N-(3-aminoethyl)-1,3-propanediamine; cmen =
The column wicking technique was applied to estimate the surface free energy of cellulose, the importance of which is to obtain a real effective capillary radiu
The critical behaviors of a mixed spin-1/2 and spin-sB Ising system with a transverse crystal field are studied by use of the effective-field theory with correl
IntroductionHerbicide safeners are the compounds which can protect crops from being injured by herbicides and enhance the tolerance of crops to herbicides. They
This paper is motivated by S. Park [10] in which the injective cover of left R[x]module M[x-1] of inverse polynomials over a left R-module M was discussed. The
A series of novel 9-fluoro-10-(4-methylpiperazin-1-yl)-3-substituted-8-oxo-8H-[1,2,4] triazolo[3,4-b]thiadiazino[6,5,4-ij]quinoline-7-carboxylic acids was prepa
A new picrotoxane type sesquiterpene named dendrodensiflorol has been isolated from the stems of Dendrobium densiflorum. Its structure was identified on the bas
Promising high strangeness dibaryons are studied by the extended quark delocalization and color screening model. It is shown that besides H particle and di-Ω,
