Investigating the Fluid-Solid Interaction of Acid Nonionic Nanoemulsion with Carbonate Porous Media.

The subject of rock-fluid interaction is important in cases where flow through porous media is occurring. One special case is when the fluid reacts with the porous matrix. In this case, the mass transfer and reaction rate control the dissolution pattern.

Protective effect of DCTN (trans-dehydrocrotonin) against induction of micronuclei and apoptosis by different mutagenic agents in vitro.

The use of medicinal plants to combat diseases has increased in the last years despite the little information available with regard to the possible health risks they represent. The aim of the present study was to determine in vitro the possible clastogenic, apoptotic and cytotoxic effects of the active principle of Croton cajucara, trans-dehydrocrotonin (DCTN), and determine its protective effect against three mutagenic agents using the micronucleus test (MN) and apoptosis index in CHO-K1 cells. Three DNA damage inducing agents were utilized in the clastogenicity and anticlastogenicity tests (methylmethane sulfonate (MMS), mitomycin C (MMC) and doxorubicin (DXR); a negative control (PBS) and solvent control were also included.
