With an acceptable safety profile, celecoxib combined with FOLFOX7 achieved RR and PFS in the lower range of that obtained with FOLFOX7 alone. These results indicate the lack of synergy between FOLFOX7 and celecoxib. PFS of 6 months appears lower than PFS obtained in OPTIMOX1 study with simplified LV5FU2 in maintenance therapy.

In the present work, AgNPs were prepared using a simple bio-reduction method. This is ecologically welcoming and cost-effective method. Yellow colored blooms concentrate of Argemone mexicana and Turnera ulmifolia are used as bio reducing agents in the study. The formation of silver nanoparticles was confirmed by UV-Vis spectrophotometer and characterization of the nanoparticles was done by FTIR, SEM, XRD and EDX. The Antibacterial action of silver nanoparticles was tested against Staphylococus aureus, Pseudomonas aeruginosa, Escherichia coli and Klebsiella aerogenes. The phytochemical analysis of the blooms concentrate has shown the existence of saponins, alkaloids, amino acids, phenols, tannins, terpenoids, flavonoids and cardiac glycosides. In vitro anti-oxidant action of both A. mexicana and T. ulmifolia AgNPs were studied by DPPH assay and reducing power assay.
