cytomegalovirus is the most important pathogen affecting transplant recipients and causing significant morbidity and morbidity. the prevalence of cmv  infections in transplant recipient varies from country to country.  the aim of this study was to determine the prognostic value of pcr assay for cmv  detection in patients before keratoplasty.  a total of 23 patient samples enrolled in this study...

Food poisoning by staphylococcal enterotoxins (SE) is a major cause of foodborne illness, often associated with coagulase-positive staphylococci (CPS). The increase in the number methicillin-resistant Staphylococcus aureus (MRSA) strains another problem CPS. However, reports association SE and coagulase-negative (CNS) are beginning to re-emerge. In this context, aim study investigate presence e...

background: weissellicin 110 is the only bacteriocin reported in weissella cibaria up to now. this bacteriocin represents several unique features. this is the first report on the gene sequence that encodes for the bacteriocin.objectives: providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives.material...

rice plants are injured at the seedling stage in early spring in northern iran. in order to study rice response to cold stress, the expression of osdreb1a, osap37, osmyb3r-2, and osnac6 genes encoding transcription factors was observed in 14-day-old seedlings of cold-tolerant genotype pr and cold-sensitive cv. hashemi during cold stress (5°c for 24 h) using the differential display method and t...

  Objective(s): Adeno-associated virus type 2 (AAV2) vectors are widely used for both experimental and clinical gene therapy. A recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. In this study, a fast and simple method is presented to generate AAV2 vector helper plasmids encod...
