متن کاملDiversity assessment and the effect of temperature and humidity on the relative abundance of medically important fly species in Fouladshahr, Isfahan, 2019
Introduction: Flies are able to mechanically transmit many pathogenic agents due to their close relationship with humans. Identification and species determination of flies for understanding of their current status and planning for their control, as well as considering the important role of flies in the ecosystem and their biological functions in biological studies, is essential. The purpose of ...

متن کاملInvestigation of Solvent Effect on CUA Codon Mutation: NMR Shielding Study
P53 is one of the gene that has important role in human cell cycle and in the human cancers too.Models of codon substitution make it possible to separate mutational biases in the DNA fromselective constraints on the protein, and offer a great advantage over amino acid models forunderstanding the evolutionary process of proteins and protein-coding DNA sequences. In thiswork, we investigated abou...
