background: recently, the use of t7 rna polymerase instead of other viral and cellular promoters is increasing due to high efficacy of transcription in the cell cytoplasm by this polymerase. in order to translate the transcripts produced by t7 rna polymerase in mammalian cell lines, it is necessary to include internal ribosome entry site (ires) sequences. in addition, if sequence of poly a sign...

a 25-year-old female presented to the infertility opd with complaints of secondary infertility and pain lower abdomen with watery discharge for the past five days. she had history of undergoing hysterosalpingography in a private hospital ten days back. the interventions included drainage of pyometra, endometrial biopsy for routine and afb smear/ culture,  confirmation of diagnosis by m rna-base...

Background: In gene therapy, the use of RNA molecules as therapeutic agents has shown advantages over plasmid DNA, including higher levels of safety. However, transient nature of RNA has been a major obstacle in application of RNA in gene therapy. Methods: Here, we used the internal ribosomal entry site of encephalomyocarditis virus and the 3’ non-translated region of Poliovirus to design an en...
