Pseudomonas aeruginosa is a nosocomial pathogen which especially causes infections among burn patients. Carbapenems are extensively used for the treatment of infections caused by multidrug-resistant P. aeruginosa isolates. The emergence of carbapenemases producing isolates is an outcome of increased utilization of carbapenems. The aim of this study was to determine the bla-IMP-1 and bla-IMP-2 genes in metallo-β-lactamase (MBL) -producing Pseudomonas aeruginosa isolated from burn patients in Isfahan.
Material and A total of 150 P. aeruginosa were isolated from burn patients hospitalized in Imam-Mousakazem hospital in Isfahan. Antimicrobial susceptibility was determined using disk diffusion method according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. Double Disk Synergy Test (DDST) was carried out for screening of MBL production in imipenem-resistant strains. PCR assays were used for detection of bla-IMP-1 and bla-IMP-2 genes among metallo-β-lactamase-producing Pseudomonas aeruginosa isolates. The purified PCR products were sequenced.
Of 150 Pseudomonas aeruginosa isolates, %100 identified as multi-drug resistant strains. The most resistance rates were seen against ciprofloxacin, tobromycin, meropenem and imipenem. All of 144 imipenem-resistant Pseudomonas aeruginosa isolates were MBL producing by DDST test. Twenty-nine (19.3%) and 8(5.3%) MBL producing Pseudomonas aeruginosa isolates harbored bla-IMP-1 and bla-IMP-2 genes respectively.
According to results of this study high level resistance to imipenem and MBl genes carriage was seen among Pseudomonas aeruginosa isolated from burn patient infections in our region.

Cystic echinococcosis or hydatid disease is a widely endemic helminthic zoonotic disease caused by infection with metacestodes the larval stage of the tapeworm Echinococcus granulosus. P-29, a 29-kDa antigen from E. granulosus, is a protoscolex specific component. The immunologic cross reactivity between P-29 and a major diagnostic antigen of E. granulosus (Ag5) indicated that P-29 might be another useful antigen of E. granulosus to be used in diagnosis or in multi epitope vaccines to prevent secondary echinococcosis. In this study, the peptide epitope regions after the identification and synthesis were evaluated in order to determine the effect of stimulating an immune response in a mouse model.
In this study, the p29 antigen epitope regions of the parasite Echinococcus granulosus detected by the IEDB Bioinformatics software and a 8 amino acids sequence were synthesized. BALB/c mice were immunized subcutaneously three times with two weeks interval. Fourteen days after last immunization spleen tissues were extracted and splenocytes were cultured in presence of antigen for 72 hours. Supernatants were collected and used for cytokine assay by Quantikine ELISA kit.
Sandwich ELISA results were analyzed and showed significant difference in IFN-γ but no significant differences observed in levels of two cytokines IL-4, IL-10, between immunized and control groups.
This study has assessed the effect of synthetic peptide EgP-29aa134-142 on the immune response and our results showed that the peptide can increase IFN-γ and therefore induce activation of innate Immunity as well as CTL and Th1 response.

The aim of this study is to compare the laryngeal view in Airtraq and Macintosh laryngoscopes.
This descriptive observational study was conducted on hospitalized patients at Shohadaye Ashayer Hospital who were candidate for elective surgery with general anesthesia. One anesthesiologist evaluated and recorded glottis view with Macintosh laryngoscopy based on cormack lehane score and another anesthesiologist who was unaware of the observations of the previous anesthesiologist evaluated and recorded glottis view with Airtraq laryngoscope.
The mean age of patients was 30.6 ± 8.89 years old. Mean BMI 22.10 ± 3.25 kg/m2 and duration of intubation was 28.3±6.92 seconds. The Airtraq laryngoscope significantly decreased the Cormack-Lehane score (P = 0.043). Cormack lehane score With the Macintosh laryngoscope was I in 187 patients (69%), II in 56 patients (21.3%), III in 20 patients (7.8%) and IV in 5 patients (1.9%) and with laryngoscope Airtraq was I in 248 cases (93.6%), II in 16 patients (5.2%) and III in 3 patients (1.1%). Improvement in view of larynx was observed in 194 cases (73.0%) with Airtraq laryngoscope and lack of improvement was seen in 73 (27.0%) cases.
Considering the high rate of improvement in observation of view of larynx with an Airtraq laryngoscope, decreasing the Cormack-Lehane score, and facilitating the tracheal intubation, Airtraq laryngoscope is a safe and useful for tracheal intubation in elective surgery with general anesthesia.

Estrogen is a steroid hormone that is in the water and cause risks for aquatic organisms, especially fish is. Estrogenic hormones naturally (caused by endocrine) or artificial (due to hormonal contraceptives such as birth control pills) to sewage and hospital to find. This study aimed to determine the amount of estrogen in the sewage and Golestan and Abuzar hospital in Ahvaz were studied.
Material and Sampling was done by tracking estrogen in the aquatic environment. 56 samples 4 months in different parts of the Golestan and Abuzar hospital wastewater treatment plant in Ahvaz were taken. Sample a little electro luminescence (ECL) were analyzed by laboratory Iranian city of Ahvaz. In this study, different forms of estrogen (estrone, 17-beta-estradiol, estriol, 17-alpha-ethinyl estradiol) has been studied as estrogen.
Mean hormone found in raw wastewater to the Golestan hospital wastewater treatment plant effluent from the treatment plant hormone 69.08 ng/l and 7.28 ng/l mean. Mean testosterone in Ahvaz Abuzar hospital treatment input 70.61 ng/l and 18.94 ng/l is refinery output. According to the results of high impact biological treatment is the removal of estrogenic compounds.
Secondary treatment of sewage is effective in reducing hormones that can do this at this stage of the biological treatment effect.

Prostate cancer is the second common cancer in men. Unluckily, as the result of the indolence of this cancer in its early stages, timely diagnosis of the disease is very difficult. Hence, in the case of this malignancy, health management and mass monitoring of the population is difficult for health organizations. Because of the incompetence of the conventional diagnostic techniques, many researches are trying to find novel biomarkers in order to develop preventive intervention, screening and targeted therapy.
Circulating Tumor Cells (CTCs) are new biomarkers originating from primary and/or metastatic tumors, and circulate in the bloodstream. Molecular properties of these new biomarkers provide valuable information about the status of the tumor and can be useful in selection of an appropriate therapy. So far lots of methods have been developed for separating CTCs, such as microfluidics technology. Despite of the recent achievements, current methods suffer from several limitations which hinder effective isolation of all subpopulation of CTCs. Thus, finding an ideal method for separating all subsets of CTSs, is still unmet. Herein, conventional diagnostic methods which are used for detection of prostate cancer are introduced and necessities of new diagnostic techniques specially, does based on CTCs are discussed. This review shows that new emerging techniques and promising biomarkers like CTCs could be effectively applied for early detection of prostate cancer and increase the chance of the successful treatment.
