The study aimed to compare the catch composition, CPUE, and CPUA of dominant commercial fishes caught by bottom trawl nets (Plan approved by the Fisheries Organization) in different depth layers of The Gulf of Oman,Sistan and Baluchistan Province. This study was carried out during 2 sampling stages in September and March 2018 (fishing seasons). Fishing operations were carried out periodically in layers of 50 meters, 50 to 100 meters, and above 100 meters by the Avash industrial trawler equipped with a bottom trawl net with a power of 2250 horsepower in 24 designated stations (4 times of net hauling per day in 6 days). Based on the calculated CPUE and CPUA results in the first stage, a significant difference was observed between the CPUE and CPUA amounts of John's snapper in the first and second depth layers, and between the CPUE and CPUA amounts of Cobia in the first and third depth layers (P<0.05). Javelin grunter (CPUE: 99.9±45 and CPUA: 2122.6±1132.2) in the first depth layer, black pomfret (CPUE: 53.6±28.7 and CPUA: 738.2±407) in the second deep layer, and longrakered trevally (CPUE: 89.9±40.2 and CPUA: 1181.6±515.7) in the third deep layer had the highest amount of CPUE and CPUA. In the second fishing stage, there was a significant difference between the amount of CPUE and CPUA of the Javelin grunter, Talang queenfish, and Cobia in the second and third depth layers (P<0.05). Javelin grunter (CPUE: 71.2±21.1 and CPUA: 1230.9±428.6) in the second depth layer and longrakered trevally (CPUE: 44.5±9.9 and CPUA: 596.2±129.3) in the third depth layer had the highest amount of CPUE and CPUA. Based on the obtained results, the highest amount of CPUE and CPUA were estimated in the first, third, and second depth layers in the first sampling stage, and in the second and third depth layers in the second sampling stage, respectively.

The intense competition in the entertainment industry force sports leagues to attract and retain their consumers by improving their brand position in their customer’s mind. Regarding the lack of reliable and standard scale for evaluating consumer brand associations for sport leagues in the literature, the aim of this study was develop a scale for measuring sports brand associations among Iranian Football League consumers. In the methodology of this study used a four-stage research design (review of research literature, Focus groups, expert review and online survey). The result of the first three steps was a structure of 18 constructs and 66 items that distributed form online survey. The research sample was selected from the focus groups of the sport management graduates (18 people) and at the survey stage from all the Iranian football fans (176 people). Then, all of the collected data were analyzed by PLS software version 3. The results of the modifying of the measurement model confirmed the scale of 18 constructs but 60 item. Finally, all of the statistical results of convergent validity, average of variance extracted, divergent validity, composite reliability and Cronbach’s alpha of constructs and items are presented in the tables of paper.

CRISPR  system (clustered regularly interspaced short palindromic repeats) and Cas portions is a part of the immune system in microorganisms. The cas genes could be involved in reducing antibiotic resistance in bacteria. The aim of the study was to investigate the frequency of cas genes of the CRISPR/Cas system in Extended Spectrum        Beta-Lactamase (ESBL) producing Escherichia coli isolated from urine culture of patients with urinary tract infection.

In this cross-sectional study, 437 positive urine culture samples were collected from Chalus hospitals. Escherichia coli strains were isolated based on standard biochemical tests and Enterobacteriaceae commercial diagnostic kit, as well as antibiotic sensitivity using disc diffusion method (Kerby Baer). Combined disk test was conducted for isolates that were resistant to at least one of the third-generation cephalosporins in the foregoing antibiotic susceptibility test. Molecular identification of cas1,cas2,cas3,cas7 and cas5 genes was performed using the PCR method.

Out of 437 urin culture samples, 106 samples (24.3%) had E.coli infection. The highest antibiotic resistance was associated with ampicillin (99%). Among the resistant isolates, thirty isolates (88.3%) were ESBL producing. cas1 gene had the highest frequency (96.2%) and other cas genes had almost the same frequency.

The results of the present study showed that a significant percentage of E. coli isolates had ESBL phenotype, which may be due to the presence of broad-spectrum beta-lactamase genes in these samples. Besides,  it was shown that there is no relationship between the presence of ESBL phenotype and the distribution of cas genes.

Achieving reality-based valuation of innovative companies is an undeniable challenge for the founders and investors of innovation. The purpose of this study is to model a logical, innovative and scalable approach to valuing innovative companies. In this way, by selecting the Earning Before Interest and Tax (EBIT) of the studied innovative company, as a state variable and simulating its future income flows based on Arithmetic Brownian Motion (ABM) standard and using the framework of Real Option Valuation (ROV) method, the valuation model was created. The accuracy and efficiency of this model was proved by extracting the data of the fiscal years from 1392 to 1395 of Gamron Petro Industry Exchange Company and comparing the results of the model with the market value of the company in Tehran Stock Exchange. On the other hand, in order to test the effect of real interest rate on the model results, by defining three different values of real interest rate, the effect of real interest rate fluctuation on the model evaluation results was investigated. Thus, the high flexibility of the model using the method of real option valuation is fully reflected in the research results.

The current trend of rising energy consumption in the world has hit mankind with two major crises: first, environmental pollution, and second, the acceleration of finishing energy supplies. Energy storage and reduction of pollutants in the city plays a crucial role in the process of maintaining existing energy. Meanwhile, the transportation sector needs attention due to its importance and position, and can annually bring significant amounts of economic savings to the people and governments by reducing energy consumption and adverse environmental effects, and reducing travel time and unwanted delays brought up. Therefore, in the present research, the most important parameters of environmental pollutant emissions in urban transport sector were determined and system dynamics model of Tehran's urban transport was developed. Based on quantitative analysis, six scenarios, Business As Usual, Priority to the Development of Public Transport, Technical Progress, Administrative Rules and Regulations Management, Travel Demand Management and comprehensive policy are evolved. According to the results, CP scenario has the best performance, and by simultaneously implementing the scenarios, each of them will play a role in improving the situation and significantly reducing energy consumption and CO2 emissions.

Various studies in electrical energy markets show that the active participation of the demand side in the electricity market, under the title of participation in demand response programs, leads to lower electricity prices, elimination of transmission line density, increasing of network security and improving the liquidity of the market. Accordingly, and in order to get the most out of these programs, it is first necessary to provide an economic model and use it to increase the willing of clients to participate. In this study, a simulation of a economic model of demand response has been performed based on price elasticity of demand and utility function. Since the demand of electricity depends on various elements of decision, such as the price of electricity, level of participation, the value of incentives and penalties specified in the demand response plans, it has been attempted to simulate them in an economical proposal. The proposed model has been evaluated using data related to the city of Tehran. And the results of the simulation have been presented in different scenarios. The results show that time-based rate programs are not sensitive to elasticity, and in any case, changing elasticity is not a determining factor in choosing the optimal policy for market decision makers, and only by changing elasticity, technical and economic indicators can be improved. But incentive-based programs and combined programs are sensitive to elasticity, and changing elasticity, in addition to improving technical and economic indicators, is a determining factor in choosing the optimal policy for market decision makers.

This study was performed to investigate the prevalence and association of blaCTX-M, blaTEM, and blaSHV beta-lactamase genes in multiple drug resistance (MDR) uropathogenic Escherichia coli resistant and susceptible isolated from patients with urinary tract infections in Chalus, Iran.

In the cross-sectional study a total of 437 samples were obtained from December 2018 to November 2019. Identification of Uropathogenic Escherichia coli strains was performed using standard microbiological and biochemical tests. Drug susceptibility to cefepime, ceftazidime, cefotaxime, cefixime, ceftriaxone, nalidixic acid, ciprofloxacin, trimethoprim, sulfamethoxazole, gentamicin, nitrofurantoin, and ampicillin was done by Kirby-Bauer disk diffusion method. Molecular identification of blaCTX-M, blaTEM و blaSHV was conducted by PCR (polymerase chain reaction) assay. The relationship between the presence of beta-lactamase genes in MDR strains was measured. Data analysis was performed using an appropriate statistical test.

It was observed that among the 437 positive urine culture samples of the patient, there were 106 UPEC strains (24.3%). The highest level of drug resistance was recognized toward ampicillin (99%), and the highest level of drug susceptibility was against cefepime (83%), and norfloxacin (82%). Multiple drug resistance (MDR) resistance was observed in 46 (43%) isolates. The blaTEM gene was more common among MDR-positive isolates (51.5%), and the blaCTX-M gene was more seen among MDR-positive isolates (65.8%).

Based on the present study results, the blaTEM gene was the dominant gene between beta-lactamase genes. Moreover, we found that the blaCTX-M gene's presence could be playing a role in MDR development.

The purpose of this study was to investigate the effect of green marketing activities on the purchase intention of customers through brand image. This study was applied in terms of purpose and correlational in terms of strategy. The statistical population consisted of all customers of Majid sports store in Tehran. 172 customers of these stores were selected by simple random sampling. Data were collected using green marketing (with α=0.75, CR=0.83) and the brand image (with α=0.83, CR=0.88) questionnaires of Juwaheer, Pudaruth & Noyaux (2012) and the purchase intention questionnaire (with α=0.83, CR=0.90) of Ko, Hwang and Kim (2013). The content validity, convergent, and divergent of the questionnaires were also confirmed by the experts, the calculation of the mean extracted variance and the cross-factor loadings, respectively. The structural equation modeling was performed using partial least squares method and Smart PLS software. The results showed that green marketing has a positive and significant effect on brand image and purchase intention of customers. Also, brand image significantly affects purchase intention of customers. Furthermore, brand image plays a significant mediator role in the relationship between green marketing and purchase intention of customers. Finally, the calculated indices showed the goodness of fit of the model. In general, it can be concluded that green marketing due to environmentally-friendly activities, can create a positive image of the corporate and its products in the minds of customers and persuade them to purchase.

Prostate cancer is the fifth most common cancer in the world and the second leading cause of cancer death among men. The ELAC2 gene (HPC2 locus) on chromosome 17p11 has been identified as hereditary tumor suppressor genes in prostate cancer. Some evidence showed that ELAC2 Ser217Leu and Ala541Thr polymorphisms were associated with prostate cancer risk. The aim of this study was to investigate the ELAC2 Ser217Leu and Ala541Thr polymorphisms in the patients with prostate cancer.

In this study, blood samples were collected from 64 persons of a family, which suspected to of having prostate cancer. The genomic DNA was extracted using Commercialthe commercial DNA extraction kit. ELAC2 Ser217Leu and Ala541Thr target regions were PCR amplified with specific primers. PCR products were then sequenced to determine mutations. The final analysis was performed using Rest 2009 software. AlsoFurthermore, SPSS software version 16 and Kolmogorov-Smirnov statistical test were used to evaluate the normality of the data and T test was used to evaluate the expression of ELAC2 gene and its relationship with T and N factors.

The results of gene sequencing for Ser217Leu mutation showed that 18.75% were mutant homozygote (Leu/Leu), 40.62% were heterozygote (Leu/Ser) and 40.62% were normal homozygote (Ser/Ser). In addition, for Ala541Thr, the Ala/Thr heterozygosity and Ala/Ala normal homozygosity were determined in 18.75% and 81.25%, respectively. There was not observed any mutant homozygosity (Thr/Thr) in these samples.

The results of this study showed that Ser217Leu and Ala541Thr polymorphisms were associated with prostate cancer and might be used as susceptibility markers of prostate cancer. In addition, PCR and gene sequencing are very useful for screening the mutations of prostate cancer in clinical trials and diagnosis.

Non-syndromic hearing loss is a genetically heterogeneous disorder. Mutation in GJB2 gene is a major cause of non-syndromic hearing loss in many countries. The aim of this study was to evaluate GJB2 mutations in 31 individuals with non-syndromic hearing loss in Guilan province.

In this descriptive cross-sectional study, blood samples were collected from 31 individuals with non-syndromic hearing loss in Rasht and Bandar Anzali cities. After DNA isolation, GJB2 gene was amplified by PCR method and underwent sequencing.

In this study, three mutations were determined in 18 individuals with hearing loss. 35delG mutation had the highest frequency (48.38%) in individuals with hearing loss as homozygote (in 14 individuals) and heterozygote (in 2 individuals). A patient with heterozygosity in V153I mutation and a patient with compound heterozygosity in 35delG/G200R mutation were determined. 

It appears that 35delG mutation is a common mutation in GJB2 gene in individuals with non-syndromic hearing loss in Guilan province

The purpose of this study was to provide an appropriate model for developing the brand equity of the Iranian Football League. Given this purpose, the present research is an exploratory inquiry into the orientation of a fundamental research that uses the strategy of the grounded theory with a classical (emergent) approach. To collect data, 24 in-depth interviews with participants of research conducted. Participants were selected theoretically through a judicious and targeted sampling method. Analysis of data was conducted during three stages of open, selective and theoretical coding. Ultimately the final model of research formed as a triplex model, including institutions, prerequisites and the specialty of branding the league. According to the results of the research, as long as there are major and structural prerequisites, the branding of the Premier League will not be fruitful; The interaction and interaction between the sovereign institutions, the media and the football institutions will determine the extent to which these requirements are met, among which the role of sovereign institutions is very high. Therefore, the organization of the Iranian Football League has been looking to facilitate and fulfill these requirements, in addition to focusing on the branding activities of the league, along with other football institutions, especially the Football Federation. Also, it is imperative for the league organization to prioritize objectives and determine the desirable position for the brand, and to follow a principled and scientific process in branding activities in order to benefit from the desired outcomes of a credible brand.

Tuberculosis (TB) is an old problem that is currently considered as a great challenge, mostly in developing countries. It may be a lethal disease. Thus, rapid diagnosis of Mycobacterium tuberculosis (MTB) infection plays a critical role in controlling the spread of TB, whereas conventional methods may take up to several weeks or longer to diagnose the infection. Hence, nested polymerase chain reaction (NCR) assay was applied for direct identification of the MTBDNA presence in sputum samples. The aim of the study was the development of a direct NCR method using mpt64specific primers for rapid diagnosis of MTBinfection.

To development of study, eight positive and negative sputum specimens obtainedfrom Masih Daneshvari hospitalpulmonary TB center, were studied. After smear preparation genomic DNA was extracted and mpt64was amplified using NCR method. While doing work we paying attention to PCR standardization and precautions to avoid sample contamination.

After evaluation gained appropriate results from purified genomic DNA by AGE and biophotometer, the standardized NCR products were evaluated by Agarose Gel Electrophoresis. Five of 7 positive samples were positive, and one of the negative samples was negative using our NCR assay.

Based on the results of this study, we could be successful in the NCR technique’s optimization to our system for disese detection,while it can be apply as a more rapid, accurate, inexpensive, and specific diagnostic assay for direct detection of MTBDNA.

HCV with millions of patients is one of the leading causes of liver cell cancer and liver cirrhosis. Based on the nucleotide differences, HCV has several types that play an important role in response to treatment. this study aims to develop a fast and accurate way to identify the most common genotypes of this virus in Iran based on the 5´-UTR region using probe hybridization method. In this study, 45 positive serum samples with a Titer of more than 1000U/mL, all of which were infected with genotypes 1a and 3a, were prepared from Golestan hospital. After designing and synthesizing the primers and probes, the system hybridization of the probe and the extraction of viral RNA with High Pure RNA Viral Extraction kit (Roche, Germany) the reaction optimization was performed. The results of the resulting genotyping were then compared with the initial results of the samples. The results obtained on the device showed that genotypes 1a and 3a have different melting point peaks with a difference of about 2 degrees. Also, the results of the initial genotyping, which was based on the sequence determination of the 5´-UTR region, are consistent with the results obtained in this study. Although the hybridization method of the probe developed in this study is not perfect and is not able to identify 7 types of HCV, but despite the high frequency of 1a and 3a Genotypes in Iran (about 90%) and the speed of reaction and its single-stage can be Use it for initial screening.

In this paper modelling maritimeinventory-routing problem for liquefied natural gas (LNG) under uncertainty of travel time is presented. We consider one hypothetical LNG manufacturer in Iran that sells its products in the form of long-term contracts and spots. The purpose of the study is to examine and compare the shipping costs of split and non-split delivery.The objective function is minimizing the operational costs, contract penalties, and spot fees, and the main constraints are liquefaction port constraints, ship flows, customer and contractual constraints. Considering uncertainty in the problem is one of this paper's contributions which is modeled by assuming vessels speed as a fuzzy parameter. The parameter and related constraints are defuzifided by Jimenez approach and for solving this problem a metaheuristic method is applied and effectiveness of results are compared with a commercial solver. According to the computational results split delivery policy in deterministic problem is cost effective but in the uncertain situation it is more costly comparing to non-split delivery policy, so split delivery is not recommended in maritime transportation with uncertain nature.

The purpose of this study was to investigate the effect of service experience on future attendance of spectators in stadiums, with mediator role of their satisfaction. This study was descriptive-correlative type. The population of the research was all of the Iran Football Premier League spectators in 2018-19 season. According to Kline (2011), 200 to 300 samples are favorable for structural equation modeling. Thus, 282 people were selected by the convenience sampling method from the spectators of Esteghlal and Persepolis teams of Tehran. Three questionnaires were used to collect data including of service experience questionnaire from Pine and Gilmore (1998), spectators’ satisfaction and future attendance questionnaires from Oh et al. (2007). The data analyzed by Partial Least Square method. Findings showed that service experience has a direct and significant impact on satisfaction and future attendance of spectators. Also satisfaction has a positive and significant impact on future attendance of spectators. Furthermore, the results showed that service experience has an indirect and significant impact on future attendance of spectators through the mediator role of satisfaction. In general, service experience can intensely predict the behavioral intention of spectators; hence, it seems that designing meaningful experiences for spectators can be a new approach to sport event organizers to gain more market share in the tourism and leisure market.

In this paper, we propose a numerical method to solve the elliptic stochastic partial differential equations (SPDEs) obtained by Gaussian noises using an element free Galerkin method based on stabilized interpolating moving least square shape functions. The error estimates of the method is presented. The method is tested via several problems. The numerical results show the usefulness and  accuracy of the new method.

American College Of Emergency Medicine (ACEM) guideline has a recommendation for early diagnosis of head injuries following mild trauma. In this study we examined the prediction power, sensitivity, and specificity of this clinical guideline in the need for computed tomography (CT) scan 

 This cross-sectional study was performed for 6 months on patients over 18 years old referred to the emergency department of Vali-e-Asr Hospital in Arak who met ACEM criteria for head CT scan for suspected mild trauma. Demographic characteristics, clinical symptoms, trauma mechanism, physical injuries caused by head trauma, and history of drug abuse were recorded. The consciousness level (Glasgow Coma Scale) was checked every two hours. Patients underwent treatment if there was a pathology in CT images, and those with no clear pathology were discharged after 6 hours and, followed up by phone for two weeks, and in case of any abnormality in the level of consciousness, they were re-examined by CT scanning.

This study has an ethical approval obtained from Arak University of Medical sciences (code: IR.ARAKMU.REC.1396.227).

500 patients, 335 male (67%) and 165 females (33%) with the mean age of 46.39± 2.01 years were studied; the sensitivity the ACEM guideline for predicting the need for CT scan in patients with mild head trauma were 100% with a specificity of 3.46% (for the second recommendation, the sensitivity was 100% with a specificity of 6.7%) which indicated that the test was highly sensitive to diagnosing the patients, but its specificity was low.

 The ACEM guideline had high sensitivity to predicting the need for CT in patients with mild head trauma, but had very low specificity which makes it an unacceptable criterion for rejecting or performing CT scan in these patients.

The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input variables (including total energy consumption, labor, capital stock, fossil fuel consumption and renewables consumption) and economic outputs (including GDP, Industry, value-added and services), has been used. The main empirical results of present study indicate that efficiency scores for models that consider total energy consumption and economic outputs in a comprehensive manner ((model M4) compared to simpler models that consider only aggregate energy and GDP data) are higher. In addition, assessment Malmquist index (MI) among Iranian provinces indicate that the efficiency in the Isfahan, Tehran, Bushehr, Ilam, Khorasan Razavi, Khuzestan, Qazvin, Markazi, Kohgiluyeh and Boyer Ahmad and Hormozgan provinces is improved.In addition, the results of this study can significantly help policymakers in decision-making process, for example, observations indicating that the change in the economic structure leads to efficiency improvement or the fact that the use of renewable resources should be gradually replaced the fossil fuel consumption, can lead to the adjustment of the Supportive policies from specific economic sectors or the expansion of specific energy sources.

The main purpose of the study is to analyze the effective factors on fiscal instability of oil-exporting countries at different levels of dependency on oil revenues based on the threshold panel approach. Due to the ineffectiveness of the overall balance-of-budget indicator in oil countries as the basis for analyzing the government's fiscal policy, in this study, "The ratio of Non- Oil budget deficit to Non- Oil GDP" is used to measure the financial instability indicator in 2006- 2015 period. The findings of the research, while confirming the existence of threshold effect (ratio of the oil revenues to total government revenues) in the model, show that with increasing government revenue due to cash seigniorage as well as rising inflation, financial instability increase. In addition, if the dependence on oil revenues is higher than the threshold level calculated (29%), the effect of dependency on oil revenue on the financial instability index is more than 3 times, when dependency on oil revenue will be lower than threshold level. The findings of this study confirm the necessity of planning and orientation in oil exporting countries in order to reduce the structural dependency of the state budget on oil revenues.

After deregulation in electricity markets, huge amount of studies were done especially in designing new systems and energy pricing in order to improve efficiency of power systems and increase investors’ profit. Investment’s profit could be increased by better contracts and better price bidding for buying and selling energy in electricity market, as a consequence price forecasting is essential. The main goal of this paper is to predict price of electricity in Iran’s electricity market, using combined of fuzzy-neural network with Particle Swarm Optimization (PSO). In this paper, past prices, past loads, working and nonworking days, day hours and effect of seasons in 1394 have been taken into account as effective factors in forecasting mechanism. Combined model, is more precise in contrast to other methods like ARIMA,neural network, neural-fuzzy network and combination of fuzzy-neural with genetic algorithm. In following, process of price fluctuations has discussed for improving and increasing effectiveness of bidding. Results of simulation revealed that price forecasting is much more precise with price process mechanism.

After restructuring the power industry, choosing a proper auction rule has been considered as a main challenge. Uniform price auctions and discriminatory (pay-as-bid) auctions have been widely used. This paper tries to compare the costs of the Electricity market under uniform auction and pay-as-bid auction using agent based modeling. Using Roth-Erev algorithm and based on the data of Iran electricity market for 2014, cost of the electricity market has been simulated and compared under the two auction mechanisms. According to the results under pay-as-bid auction, diversion of players from their marginal costs is more likely mainly because of its settlement rules. Since Iran's electricity market is ruled under pay-as-bid auction, revision in its auction structure is recommended to the Electricity Market Regulatory Board.

V617F mutation of JAK2 gene is a point mutation of Somatic cells leading to permanent phosphorylation and protein kinase activity of the JAK2 protein. This mutation is a valuable marker in the diagnosis of myeloid neoplasms. Development of new techniques can be effective and highly sensitive for the detection of the mutation. The aim of this study is designing and executing a molecular beacon probe-based real-time PCR detect to V617F mutation. Test results were reviewed from a set of wild type and cloned JAK2 exon 12 mutated allele genes into plasmid vector and through amplification by Real-Time PCR system. The sensitivity and specificity of Molecular Beacon probes design were tested. The results showed that the Real-Time PCR system has %100 specificity and % 0.001 sensitivity. Based on the results obtained from the molecular beacon probe-based real-time PCR, it was proved that the system is able to detect normal and mutant alleles of JAK2 V617F position with high accuracy and a short time in a closed tube system.

Human T-cell lymphotropic virus type 1 (HTLV-1) is a human retrovirus that causes two distinct diseases, adult T-cell leukemia (ATL) and a progressive and degenerative myelin disorder called myelopathy associated with HTLV-1 (tropical spastic paraparesis). Similar to human immunodeficiency virus (HIV), infections caused by HTLV-1 and -2 and retroviruses are persistent and long-lasting. Less than 5% of these infections are HTLV-related illnesses, but their treatment modalities are rare and their prognosis is poor. They are often fatal. Patients with β-thalassemia major are clearly at higher risk for HTLV-1 infection due to the need for frequent blood transfusions. The current study aimed at detecting the molecular screening for HTLV-1 infection based on fluorescent probe in patients with β-thalassemia. The current experimental study was conducted on 80 blood samples collected from patients with β-thalassemia major in Shahid Rajaee Hospital of Tonekabon, Iran. After DNA extraction by the Iranian kit, molecular biological system transfer (MBST) Cinna Gen company (Tehran, Iran), TaqMan real-time polymerase chain reaction (RT-PCR) was employed to detect DNA HTLV-1 genome and a tax gene-specific integrated with the genome of patients’ lymphocyte was obtained. Results of TaqMan RT-PCR indicated that out of 80 patients with β-thalassemia major referred to Shahid Rajai’e Hospital, two (2.5%) had HTLV-1. Compared to other molecular and serologic techniques, HTLV can be applied to detect HTLV-1 in blood banks due to its sensitivity, simplicity, higher speed, and the ability to simultaneously diagnose HTLV and lower costs than that of fluorescence molecular methods
