Iran, one of the countries with a relatively high number of positive cases, has an inevitable role to play in controlling the pandemic by implementing effective policies and countermeasures to interrupt the viral transmission chain. Epidemic restrictions implemented following an Iranian presidential mandate were especially effective following the Nowruz holidays—the solar New Year celebration in the Persian-speaking culture. These restrictions started flattening the incidence curve of the epidemic in Iran two weeks after implementation, from 10 April 2020. Supplying sufficient face masks, disinfectants, sanitizers, and medical equipment to all government-run and non-for-profit hospitals were included in the presidential mandate. We believe that continuing this policy strictly will be required for further controlling the pandemic throughout the country. \u0000*Corresponding Author: Amin Talebi Bezmin Abadi; Email: amin.talebi@modares.ac.ir \u0000Please cite this article as: Talebi Bezmin Abadi A, Rahimi F.

Anbari, Faranak Rezaei","doi":"10.22037/AMLS.V6.32905","DOIUrl":"https://doi.org/10.22037/AMLS.V6.32905","url":null,"abstract":"Background and Aim: Microbiological culture of dialysis water is a routine safety measure. In, Khorramabad laboratories perform these cultures on Muller Hinton Agar (MHA) at 35–378C for 48 h, not on the Reasoner’s 2A agar (R2A agar) at 17–238oC for 7 days recommended by international standards, the objective of the present study was the comparison of the efficiency of R2A and MHA media in the counting of heterotrophic bacteria in the samples of water collected in dialysis centers from 2 hospitals in Khorramabad, from September to November 2019. \u0000Methods: A total of 165 samples of treated water in dialysis centers were collected aseptically and then transported in ice‑packs to the Department of Medical Microbiology of the Lorestan University of Medical Sciences and the pour plate technique was carried out for the enumerating of heterotrophic bacteria. Finally, bacterial colonies were counted after incubation at 34±2oC for 48 hours on MHA and 25oC for 1 week on R2A. \u0000Results: Results showed heterotrophic bacterial counts in R2A were greater than those in MHA in 89% of the samples, so enumeration of heterotrophic bacteria should be carried out in R2A agar associated with longer incubation times, because of the greater sensitivity. The proportion of water samples yielding colony counts ≥200 CFU/mL by R2A -7d was significantly different from the proportion by MHA-48h (p<0.001). \u0000Conclusion: The results proposed using R2A agar combined with relative low culture temperature (20-25°C), and an extended incubation time (7-10 days) is more efficient. However, as the spectrum of bacterial contamination is not similar for dialysis centers and countries, many studies using different media and culture parameters are required to confirm this. \u0000*Corresponding Author: Faranak Rezaei; Email: Rezaei.f@lums.ac.ir \u0000Please cite this article as: Pouladi I, Delfani S, Hadian B, Soroush S, Anbari K, Rezaei F.

Hence, the evaluation of sperm production after chemotherapy has been the subject of several studies today. \u0000Methods: Adult male albino mice weighing 20±2 g were randomly divided into 5 groups (n = 4);control, cyclophosphamide (12 mg/kg/day), cyclophosphamide and vitamin E (200 mg/kg/day), cyclophosphamide and retinoic acid (500 µL/72h), cyclophosphamide and retinoic acid (250 µL/72h) and vitamin E (100 mg/day).

Various methods are used to transfer the DNA/RNA sequence into cells, such as lipid-based carriers as the available and easy procedure. Transfection with cationic lipid liposome is introduced as a simple and efficient procedure for monitoring the DNA/RNA sequence through gene function analysis, including fluorescence imaging RNA and protein expression. This study aimed to investigate the transfection efficiency and cell death through GFP expression in human esophageal squamous cell carcinoma (ESCC) cell line KYSE-30 using Lipofectamine 3000 reagent. Methods: The pCDH-513b plasmid DNA was transfected into KYSE-30 cells using Lipofectamine 3000 in different concentrations of the plasmid DNA and reagent. The transfection efficiency was evaluated by fluorescence microscope and flow cytometry analysis to determine the percentage of GFP-expressing cells. Moreover, the viability and death of transfected KYSE-30 cells were evaluated using a trypan blue exclusion assay. Results: The transfection efficiency of KYSE-30 with Lipofectamine 3000 was increased with higher plasmid DNA concentration and a lower amount of Lipofectamine 3000 reagent. The Optimized concentration of 1.5 µg plasmid DNA and volume of one µl of lipofectamine 3000 reagents were identified for 95% transfection efficiency in the KYSE-30 cell line. The viability and death of transfected cells were 43% and 58% after transfection, respectively. Conclusion: The results indicated that Lipofectamine 3000 might not be suitable for transfection in KYSE-30 cells due to increased cell death. \u0000*Corresponding Author: Mohammad Reza Abbaszadegan; Email: abbaszadeganmr@mums.ac.ir \u0000Please cite this article as: Mahmoudian RA, Farshchian M, Abbaszadegan MR.

The detection of AmpC-producing Escherichia coli has a high priority in infection management. This research is aimed to investigate the resistant AmpC- generating E. coli isolates and identify their genetic variety. \u0000Methods: In this study, 230 E. coli isolates from patients having urinary tract infection symptoms were investigated in 2017-2018 to assess their susceptibility toward antimicrobial agents. AmpC genes were evaluated by PCR and molecular typing using the 10-loci MLVA method. MLVA images were examined by BioNumerics 6.6 software through the use of the UPGMA algorithms. \u0000Results: The highest frequencies of susceptibility among E. coli isolates were to meropenem 96.08%, piperacillin-tazobactam 90.43%, followed by gentamicin 66.54%, ceftazidime 50%, ciprofloxacin 48.26%, ceftriaxone 41.74%. All E. coli isolates were resistant to amoxicillin-clavulanate. Thirty-eight AmpC-generating E. coli isolates were detected. The most abundant determinant was CIT and EBC, FOX, and DHA had the next ranks, respectively. Six major clusters and a singleton were identified by MLVA. \u0000Conclusion: AmpC-generation ability is an effective feature in the resistance of E. coli isolates and its investigation is of crucial significance in infection management.

The V617F mutation in the pseudokinase domain of JAK2 protein has been detected in a majority of patients. We aimed to evaluate the frequency of this somatic missense substitution among Iranian patients with myeloproliferative neoplasms. \u0000Methods Peripheral blood samples were collected from patients with myeloproliferative neoplasms across different regions of Iran. The JAK2 V617F mutation was identified by allele-specific PCR. To confirm the PCR results, randomly selected positive and negative samples were sequenced. \u0000Results: Among 72 identified patients, 45 (62.5%) were found to harbor JAK2 V617F. The frequencies of the mutation ranged 100% for primary myelofibrosis, 75% for chronic myelogenous leukemia, 67% for polycythemia vera, 62.5% for myelodysplastic/myeloproliferative neoplasms, and 52% for essential thrombocythemia. Our findings revealed that the mutation was more common among men in comparison with women and the correlation between the mutation and gender was statistically significant (p-value<0.01). Additionally, the presence of JAK2 V617F was associated with older ages (p-value =0.009). \u0000Conclusion: The JAK2 V617F mutation was detected in 62.5% of patients with myeloproliferative neoplasms.

Studies have shown that expression of PPAR alpha improved insulin function in patients with insulin resistance. Also ApoB100 is an essential ligand for the receptors of low-density lipoproteins (LDL).

Infectoria and 5- Z. multiflora groups. All groups were fed with high fat diet for 6 weeks expect for the healthy control. Glucose tolerance test was performed to confirm insulin resistance in rats. Then groups 3, 4, and 5 were treated by fenofibrate , Q. Infectoria and Z. multiflora extracts respectively. After sacrificing the rats, their liver and fat tissues were removed.
