Skin cancer has been reported as a contemporary malignant cancer. Here, anti-cancer effects of sea cucumber extract (SCE) from Holothuria arenicola have been examined on melanoma cells and compared with imidazole carboxamide (Dacarbazine) as a chemotherapy medication against melanoma and Hodgkin's lymphoma. MTT assay and morphological analysis were performed to evaluate cytotoxic effects of H. ...
recent studies have indicated that 1, 4-dihydropyridine-3, 5-dicarboxamidederivativesshow significant anti-tubercular activity. in this research, new derivatives of 1, 4-dihydropyridine were designed and synthesized using hantzsch condensation in which dicyclohexyl and different dicyclohexylcarbamoylwere substituted at c-3 and c-5 positions of the dhp ring.in addition, 4 (5)-chloro-2-methyl-5 (...
Froth flotation has been a key chemical process extensively used in the recovery of heavy metal ions (e.g. Cu2+) from contaminated water, while often criticized by secondary pollution added collectors, and less selectivity to specific since ion removal particles is independent post-step particle flotation. To facilitate industrial operation, “smart” with foams responsively stabilized after sele...
Protonation of the highly reactive 1:1 intermediates, produced in the reaction between triphenylphosphine and acetylenic esters, by NH-acids such as azathioprine, imidazole or theophylline leads to the formation of vinyltriphenylphosphonium salts, which undergo a Michael addition reaction with a conjugate base to produce phosphorus ylides. Silica nanoparticles (silica NPs were prepared by therm...

Mechanism and regulation of high temperature and high salt tolerance polymer polymerization behavior
Abstract In this study, the molecular dynamics simulation of imidazole-modified polyacrylamide (VPAM) and (PAM) system showed that VPAM containing had better cohesion-bonding effect than PAM without imidazole. Based on imidazole-containing system, cohesion properties functional monomers mechanism in process were analyzed at high temperature salt, structure-activity relationships between chemica...
