in the present study, theoretical chemical reactivates photo isomerization in cis-retinal as a natural photo switch in vision. dft hybrid functional, b3lyp and, post-hf method, were the theoretical methods applied utilizing g09 software. 6-31g+ (d,p) basis set employed for structural optimizations, and single point computations performed using b3lyp/6-31g+(d,p). the isomers cis molecule retinal...

En este artículo se reportan resultados experimentales de interacciones del aminoácido L-cisteína (Cis) con nanopartículas oro (AuNPs) y funcionalizadas Cis (AuNPs+Cis) cuando incorpora en la solución iones As3+. los procesos agregación evalúa el papel concentración funcionalización, además tamaño las a agente iónico interés. Los muestran una sensible dependencia nanosondas AuNPs+Cis función su...

To determine the effect of giving a combination Annona squamosa leaf extract and cisplatin on matrix metalloproteinase-9 expression inhibition cell migration in HeLa cells. The sample this study was divided into 6 groups: group 1 as control group, 2 single (Cis) 3-5 different combinations with ASL 12.5, 25 mg/mL, 50 mg/mL respectively, 75 group. This research included cytotoxicity test MTT assa...

using a time-dependent-density functional theory (td-dft), configuration interaction singles (cis) and zerner’s intermediate neglect of differential overlap (zindo) methods, we have investigated the uv-visible spectra of one new intramolecular cyclization at before and after intramolecular attack. all structures were optimized at the b3lyp/6-311++g** level while uv-visible parameters were calcul...
