in the present work, the interaction of three water soluble porphyrins, tetra (p-trimethyle) ammoniumphenyl porphyrin iodide (tapp) as a cationic porphyrin, tetra sodium meso-tetrakis (p-sulphonatophenyle) porphyrin (tspp) as an anionic porphyrin and manganese tetrakis (p-sulphonato phenyl)porphinato acetate (mntspp) as a metal porphyrin, with dna have been studied by isothermaltitration microc...

Abstract To protect the images and provide a more secure cipher image, DNA encoding is crucial in image encryption. Applying single, easily detectable coding rule to during has no impact on encryption model's security level. Therefore, using various rules while applying dynamic DNA-coding techniques have emerged strengthen improve of its security. This study integrates method with an model. The...

Background There has been a growing claim about the stress induced by the modern life and especially by cell phones. It may have detrimental effect on sperms. We examined the relationship of stress caused by cell phone radiation and the effect of Zinc and Alpha-tocopherol on the sperms and its chromatin in this condition. MaterialsAndMethods Fresh semen has been collected from 20 young men. Eac...

Progress in DNA-encoded chemical library synthesis and screening crucially relies on the availability of DNA-compatible reactions, which proceed with high yields excellent purity for a large number possible building blocks. In past, experimental conditions have been presented execution Suzuki Sonogashira cross-coupling reactions on-DNA. this article, our aim was to optimize comparing results pr...

DNAzymes have attracted increasing interest in developments of gene tools, therapies, and biosensors. Among them, G-quadruplexes are widely used as the key structure elements to activate catalytic competency specific cofactors, such hemin, but there is a great demand diversify using other more straightforward DNA structures fully matched duplex (FM-DNA). However, perfect base pairs limit DNAzym...
