conclusions adsorption of antibodies to bap might interfere with bacterial adhesion to the surface. these antibodies were found to be potent biofilm inhibitors. results injection of bap subunit resulted in high titers of antibody. immunized mice serum had significant (p< 0.001) inhibitory effect on biofilm formation. in vitro inhibition of biofilm formation by a. baumannii was studied at 1:50 c...
background: acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. in this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influence of low iron concentration on expression of the biofilm-associated protein gene (bap) in development of biofilm...
acinetobacter baumannii به عنوان یک باکتری بیماریزای بیمارستانی که دارای مقاومت به بسیاری از انواع آنتی بیوتیک ها می باشد، به حساب می آید. از این رو، یک روش تشخیصی سریع، حساس، اختصاصی و به صرفه، برای شناسایی آن ضروری به نظر می رسد.وجود این میکروارگانیزم هنوز با استفاده از روش های سنتی کشت مشخص می شود و شناسایی آن نیز از طریق روش های بیوشیمیایی. روش سنتی ذکر شده، زمان بر بوده و برای اعلام نتیجه،...
We employed the suppressive subtractive hybridization to identify 41 up- and downregulated transcripts in Jurkat cells after benzo[a]pyrene (BaP) treatment. Among the 21 downregulated transcripts, we found that BaP suppresses the Keap1 transcript by 7.5-fold. Subsequent analyses revealed that BaP significantly suppresses the Keap1 message and protein levels to about 40 and 60%, respectively, of...
objective: acinetobacter baumannii (a. baumannii) is a major hospital pathogen with a high capacity to resist most common anti-microbial agents. a. baumannii is the etiologic agent for various illnesses including pneumonia, meningitis, and bloodstream infections. biofilm associated proteins (bap) are specific cell surface proteins essential for the formation of biofilm and play a main role in i...
The biofilm matrix, composed of exopolysaccharides, proteins, nucleic acids and lipids, plays a well-known role as a defence structure, protecting bacteria from the host immune system and antimicrobial therapy. However, little is known about its responsibility in the interaction of biofilm cells with host tissues. Staphylococcus aureus, a leading cause of biofilm-associated chronic infections, ...

lentiviral vectors are among the promising viral based-vectors in gene therapy applications, but the efficiency of their targeting needs to be improved. (strept)avidin-biotin adaptor system is a novel approach to modify the lentiviral envelope for better targeting properties. herein, we describe utilization of this adaptor system by designing a candidate envelope protein-bearing biotin acceptor...
The cytochrome P450 (CYP1A1) enzyme metabolically activates many polycyclic aromatic hydrocarbons, including benzo[a]pyrene (BaP), to DNA- and protein-binding intermediates that are associated with toxicity, mutagenesis, and carcinogenesis. As a result, it is widely accepted that CYP1A1 potentiates the toxicity of this class of chemicals. In distinct contrast, we show here that CYP1A1 inducibil...
Previous studies in this laboratory have demonstrated that transcriptional deregulation of c-Ha-ras expression is associated with the induction and maintenance of proliferative vascular smooth muscle cell (SMC) phenotypes by benzo[a]pyrene (BaP). We examined previously undescribed cis-acting elements within the proximal 5' regulatory region of c-Ha-ras (-550 to +220) for their ability to influe...
