introduction: neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in human. pora is a major component of the outer membrane of n. meningitidis and functions as a cationic porin. this study aimed to clone and determine the expression of pora as the first step for producing a proper antigen in a vaccine study against n. meningitidis. methods: an approximately ...

Nasopharyngeal swab collection for SARS-CoV-2 examination by RT-PCR requires Viral Transport Medium (VTM) using VTM non-activated and inactivated. This study determined the difference in CT values SARS CoV-2 inactivated VTM. is a comparative analytical with cross-sectional method 20 confirmed positive samples at RSU. Dr. Suyoto was analyzed T-Independent test (N gene) Mann-Whitney (ORF1ab SPSS ...

Background: Sperm mediated gene transfer was approved for producing transgenic animals. There are many studies which reported different success rate by this procedure. Failure in this project mostly is returned to transfection and stability of transferred genes. The other problem that may contribute in project failure may return to the testicular damages which occur at the time of transfection,...

Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (NTAD). We aimed to find a correlation between the length of this polymorphic tract and azoospermia or oligozoospermia in infertile men living in Khuzestan, Iran. MaterialsAndMethods In this case-control study during two years till 20...

background and objective: nowadays, the presence of extended-spectrum β-lactamases (esbls) producing strains in serratia genus causes the emergence of resistance to many antibiotics. so, the lack of proper diagnosis of esbls strains can lead to failure in the treatment. the objective of the present study was to investigate esbls production in serratia strains isolated from the clinical blood sa...

The present study was aimed to construct a fusion plasmid harboring the extracellular domain of the influenza A M2-protein (M2e), which was fused to the N-terminus of the truncated HSP70 (HSP70359–610) molecule as a new approach for future vaccine research against influenza A. The amplified fragments, M2e and HSP70359-610 genes, were gel-purified. The products were then single digested with Bam...
