Background: Tuberculosis (TB) with more than 10 million new cases per year and one of the top 10 causes of death worldwide, is still one of the most important global health problems. Also, multi drug-resistant tuberculosis (MDR) is a serious danger to public health. Understanding of the epidemiological pattern of mycobacterium tuberculosis (MTB), Estimates of recent transmission and recurrence of infection, it is possible with molecular typing methods. The present study was performed aiming to track and determine the type of Mycobacterium tuberculosis infection, as well as its relationship with demographic factors, using PGRS-RFLP. Materials and Methods: In this study, 90 samples collected from TB patients from the North West provinces of Iran, Molecular typing by Characterization highly abundant polymorphic GC-rich-repetitive sequence. Investigated Demographic factors associated with the transmission of the disease. Results: All isolates were grouped into 44 clusters 28types (33.3%) of the subspecies were in unique stains and 66.7% (from 56 patients) had clustered isolates. The largest cluster contained 8 isolates (9.52%) was the West provinces of Iran. Conclusion: Genetic variation of Mycobacterium tuberculosis is high in this region. The rate of recent transmission based on clustering was unexpected (The global average is 30%-40%). The recent transmission was more dynamic in the west than northwest Iran. Clustering based on PGRS-RFLP can demonstrate the high correlation between molecular and classic information. In addition, the significant relationship between vaccination record and clustering highlights the necessity to conduct more extensive studies.

Background: Molecular methods are nowadays used to diagnose diseases, produce vaccines, drugs and recombinant proteins. Therefore, one of the important steps in these procedures is selecting the appropriate vector for cloning and expression of the target genes. Because the expression of synthetic polygenes or so-called chimeric antigens with high molecular weight requires special conditions, the aim of this study was to evaluate the importance of vector type for expression of such antigens. Materials and Methods: The 1250bp sequence consisting of epitopes from eight important antigens of Leishmania infantum parasite was designed and synthesized by Biomatic Company (Cambridge, Canada). The sequence was cloned separately in two expression vectors pET25b and pET32a and then transformed into E.coli BL21 (DE3) and expressed under similar appropriate conditions. Bacterial lysates were analyzed by SDS PAGE and evaluated by Western blotting. Results: of SDS- PAGE and Western blot analysis showed that intact recombinant protein production by pET25b vector was not successful. However, the recombinant protein resulted from the expression of the aforementioned poly-epitope in pET32a vector was successfully produced and confirmed. Conclusion: According to the successful expression confirmation of the poly-epitopic sequence within the pET32a vector and furthermore the failure to obtain protein in the pET25b vector showed that in the case of some specific mosaic sequences expression, protein isolation will be difficult because of low solubility. So, the expression vector choose should be made more carefully.

Background: Giardia is one of the infectious agents that can be transmitted by surface water and cause a disease. We designed and fabricated a magnetic system to separate the giardia cysts from water. Materials and Methods: In this study, giardia cysts were concentrated by sucrose floatation method. The cysts were mixed with physiological saline and their concentration was adjusted to 100,000 cysts per cubic millimeter using Neubauer slide. The isolated cysts were passed through the magnetic field generated by the 200-msT magnets. The cysts were attracted to the magnet and removed from the suspension. The cysts were exposed to magnetic field for one week in order to evaluate the effect of magnetic field on their survival, which was reported as 0.1% using eosin staining under a light microscope. Results: The results showed that magnetic field can relatively absorb giardia cysts from water, the survival rate of the cysts did not change significantly in different days (P≥0.05). Conclusion: The designed magnetic system can be reinforced to isolate giardia cysts, which is economical and has no chemical effects on water.

The quintuple helix innovation model has been introduced by E.G. Carayannis and F.J. Campbell. The natural environments of society and the economy are major drivers of this innovation model. The third generation university (the convergence of government, industry and university), the fourth generation universities (the convergence of government, industry, university and civil society) and the fifth generation university (the convergence of government, industry, university, civil society and bio-environment) perform within Triple Helix, Quadruple Helix and Quintuple Helix models, respectively. According to the viewpoints of Carayannis and Campbell, the cardinal characteristics of the fifth generation university could be conceptualized as a knowledge-based innovation system which is sensitive to natural environment of society, produces knowledge within the mode 3 knowledge production framework, supports co-evolution and co-existence of different knowledge paradigms, shapes co-opetitive ecosystem for knowledge management and promotes knowledge democracy.

Background: Recycling is one of the most important measures to manage the municipal solid waste. In order to design a training program, it is necessary to identify the factors that influence behavior. Therefore, the present study aimed to investigate the predictive factors of recycling behavior among residents of Bushehr city based on the extended theory of planned behavior. Materials and Methods: In this cross-sectional study, 582 people were selected through convenience sampling method. A questionnaire with items on demographic characteristics, extended theory of planned behavior, and recycling behavior was used for data collection. The collected data were analyzed by SPSS software version 20. Results: In this study, 221 participants (38%) adhered to recycling behavior. There was a significant relationship between knowledge of waste collection program (P<0.001), receiving recycling incentive packages (p=0.003), and recycling waste disposal vehicles (p= 0/001) with recycling behavior. Past behavior (OR=0.229, P<0.001), and descriptive norms (OR=1.187, P=0.003) were predictive of recycling behavior. Conclusion: The results of the present study indicate that regular refuse collection vehicles, providing environmental facilities including incentive packages, and informing citizens about the schedule of refuse collection vehicles can lead to recycling behavior. Also, friends, relatives, and family are role models for other members by establishing norms and are effective in promoting recycling behavior. Having a positive experience of a behavior is necessary for its maintenance.

Background: Olfaction plays an important role in human life and promotes quality of life through under-standing various odors. Nasal polyps are among the common causes of olfactory impairment. There are many different treatment options for polyps most notably the diagnosis and elimination of underlying causes. Some polyps do not respond to medication therapy or they relapse, and therefore require surgery. The present study aimed to determine olfactory function in patients with sinus and nasal polyposis before and after endoscopy. Materials and Methods: In this cross-sectional study, patients admitted to, Vali e Asr Hospital of Birjand in 2015 for endoscopic nasal polypectomy were included. Evaluation of olfactory quality was performed prior to and four weeks after the surgery. Olfactory function was evaluated by a semi-structured questionnaire on the quality of olfactory, taste and appetite combined with the Quick Odor Detection test. Data was analyzed in SPSS 23 software using descriptive statistics of frequency, perentage, mean and stand-ard deviation, and analytical statistics of McNemar’s and Wilcoxon tests. P value of <0.05 was considered significant. Results: Thirty-six patients were enrolled. All patients underwent endoscopic polypectomy. Their mean age was 39.14±11.69 years. Most of them were male (n=21, 58.3%). History of nasal polyps, asthma, allergic rhinitis and aspirin sensitivity was positive in 27.8%, 11.1%, 47.2% and 27.8% of patients. Nasal polyps were unilateral in 58.3% of patients and bilateral in 41.7% of patients. There was a significant improvement in olfactory quality after surgery (p<0.001). The sense of smell was present in 75% or the patients before and in 100% of them after the surgery, and the difference was statistically significant (p=0.004). Conclusion: Olfactory dysfunction in patients with polyps is remarkably prevalent. Overall, the results of this study show polypectomy significantly improved patients’ sense and quality of smell.
背景:嗅觉在人类生活中扮演着重要的角色，通过对各种气味的了解来提高生活质量。鼻息肉是嗅觉障碍的常见原因之一。息肉有许多不同的治疗选择，最显著的是诊断和消除潜在的原因。有些息肉对药物治疗无效或复发，因此需要手术治疗。本研究旨在确定鼻窦和鼻息肉患者在内镜检查前后的嗅觉功能。材料与方法:本横断面研究纳入2015年在Birjand Vali e Asr医院行内镜下鼻息肉切除术的患者。嗅觉质量评估在手术前和手术后四周进行。嗅觉功能评估采用半结构化的嗅觉、味觉和食欲质量问卷，并结合快速气味检测测试。采用SPSS 23软件进行数据分析，采用频率、百分比、均值、标准差描述性统计及McNemar检验和Wilcoxon检验的分析统计。P值<0.05。结果:36例患者入组。所有患者均行内镜下息肉切除术。平均年龄39.14±11.69岁。以男性居多(n=21, 58.3%)。鼻息肉史、哮喘史、变应性鼻炎史和阿司匹林敏感性史分别为27.8%、11.1%、47.2%和27.8%。单侧鼻息肉占58.3%，双侧鼻息肉占41.7%。术后嗅觉质量有显著改善(p<0.001)。术前75%的患者嗅觉正常，术后100%嗅觉正常，差异有统计学意义(p=0.004)。结论:嗅觉功能障碍在息肉患者中非常普遍。总体而言，本研究结果显示息肉切除术显著改善了患者的感觉和嗅觉质量。

Background: Heavy metals enter the environment through industrial activities and contaminate natural ecosystems. Identification of heavy metal-resistant bacteria plays an important role in environmental pollution and ultimately cleansing it. Therefore, the aim of the present study was to isolate the resistant genes of Pseudomonas aeruginosa and the effects of nanoparticles on gene expression using real-time PCR. Materials and Methods In this descriptive cross-sectional study, 60 isolates of P. aeruginosa were studied. Frequency of czr gene was determined by PCR. Also, the effects of iron nanoparticles on czr gene expression were evaluated by real-time PCR after RNA extraction. Results: In this study, 25 isolates were carriers of czr gene. Also, iron nanoparticles could reduce the expression of the heavy metal resistance gene in P. aeruginosa in vitro. Conclusion: This study showed that the resistance of different species of P. aeruginosa to the heavy metal cadmium is different.

Background: Cardiac catheterization and angiography are diagnostic and therapeutic imaging modalities that produce the highest X-ray radiation, which might impose lifelong risks to patients. This study aimed to evaluate radiation burden among children and adolescents with congenital heart diseases, who underwent cardiac catheterization and angiography. Then the results were compared with other imaging modalities. Materials and Methods: In this prospective study, children and adolescents with congenital heart diseases were consecutively evaluated from April 2017 till November 2017. This research was designed in Namazi and Faghihi teaching hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. In addition to the basic data and total radiation time, effective dose and dose area product were assessed for each patient. Results: We enrolled 148 consecutive patients under 18 years old, who underwent 36 diagnostic and 112 interventional cardiac catheterizations. Effective dose was 50.23 mGy in the diagnostic catheterizations, and 48.39 mGy in the interventional angiographies. Also the dose area product was 427/28 mGy.cm 2 in the diagnostic catheterizations, and 476.62 mGy.cm 2 in the interventional angiography. The most time-consuming cine fluoroscopy pertained to ventricular septal defect closure and (11.67 seconds) and the most effective dose and dose area product pertained to the same procedure, as well (68,514 mGy and 623,843 mGy.cm 2 respectively). Conclusion: Effective dose and dose area product in cardiac catheterization were desirable, and some previous studies revealed that carcinogenic effect of X-ray radiation is more prominent when effective dose is more than 70-100 mGy. Thus the effective dose might not cause hazardous outcomes if other x ray modalities are not frequently requested for them in future.

Background: The birth of a child with authistic spectrum disorder is a challenge to the family, especially to mothers. The purpose of this research was to compare the effectiveness of acceptance commitment therapy and coping strategies in decreasing anxiety and despair in mothers of children with autism. Materials and Methods: This qausi-experimental multigroup pre-test, post-test design with a control group enrolled 30 mothers of children with autism who were being treated in teaching-treatment centers of Booshehr city using convenience sampling. They were randomly classified into three groups. The experimental groups participated in eight sessions of 90 minutes in 8 weeks, while the control group did not receive any interventions. Beck Anxiety Inventory and Beck Hopelessness Scale were used to collect research data. The collected data were analyzed by multivariate analysis of covariance and Tukey post hoc test. Results: Results showed that acceptance commitment therapy and training coping strategies significantly decreased anxiety and despair in mothers in the experimental groups compared to those in the control group (p<0.01), but the decrease was not significant in the follow-up stage. Tukey's test showed acceptance commitment therapy was significantly more effective for anxiety than training coping strategies in the post-test (p<0.01). Conclusion: Our findings showed that both treatments were effective in decreasing anxiety and despair. Hence, therapists can use these two therapeutic and training approaches, especially acceptance commitment therapy, which is a new wave of cognitive – behavioral therapy.
