Objective(s): The present study aims to evaluate the protective effect of the compounds isolated from Echinophora cinerea (E. cinerea) against oxidative stress and apoptosis induced by cisplatin (CIS) in PC12 cells. Materials and Methods: Six compounds were isolated as quercetrin-3-O-β-D-glucopyranoside (QUE), osthol (OST), verbenone-5-O-β-D-glycopyranoside (VER), Isoimperatorin (ISO), kaempfer...

The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...

Opalized white tuff (OWT) with 40 μm average particle size and 39.3 m(2)/g specific surface area has been introduced into polyisoprene rubber (NR). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PSi). The cure characteristic, apparent activation energy of cross-link (E(ac)) and reversion (E(ar)), and mechanical properties of a variety of composites ...
