 Background & Objectives: Effects of new educational programs on health and physical fitness promotion is an important issue which needs regular evaluations. Physical fitness has many advantages such as cardio-respiratory health promotion, prevention of some diseases and improvement of quality of life. On the other hand, it has been shown that there is significant relationship between waterpipe smoking and cancer, cardiovascular as well as pulmonary diseases. The aim of this study was to evaluate the relationship between addiction to waterpipe smoking and cardio-respiratory fitness and body composition of physical education students in Islamic Azad University, Ardabil Branch.

 Methods: One hundred and eighty-one physical education students participated in this study. All subjects were selected by cluster sampling method. Cardio-Respiratory fitness (using Cooper test), Body Mass Index (BMI), Fat percent (using 2-point Lohman equation), addiction to waterpipe smoking, smoke exposure and awareness of waterpipe effects on athletic performance (using questionnaire) were evaluated.

 Results: The body composition of the most students was not suitable (50.3% extra fat), but the cardio-respiratory fitness of male students was better than that of female students.

 Furthermore, In spite of decrease in waterpipe smoking in comparison to last year (13.3% versus 35.6%), many non-smoking students are exposed to waterpipe smoke (21.0%) and some of them (48.1%) had little information about the harmful effects of waterpipe smoking on athletic performance.

 Conclusion: According to results of this study improvement in cardio-respiratory fitness and body composition of physical education students and enhancement of their information about side-effects of waterpipe smoking should be emphasized

  Background & Objectives : Several studies have been conducted to explore anti-HIV drugs. Discovery and study of novel anti-HIV-1 compounds need live viruses and has serious biosafety concerns. In this research we reported a novel and safe system for assaying the cytopathic effects of HIV by using single cycle replicable (SCR) HIV-1 virions.

  Methods: To produce the SCR HIV-1 virions, pMD2G, pmzNL4-3 and pSPAX2 plasmids were co-transfected into HEK293T cells. Different amount of SCR virions were used to infect target cells (MT-2). Within the infected cells, the number of formed syncytia was counted under the light microscopy. The lethal effects of the SCR HIV virions were measured using XTT proliferation assay.

  Results: Formation of syncytia among SCR HIV infected cells was detectable 24 hours after infection. Highest amount of syncytia was seen 72 hours after infection. Increase in the amount of virions caused increasing of syncytia and the cytopathic effects of SCR HIV-1. Infection with more than 1600ng P24 SCR HIV decreased the syncytium formation and viability of all cells. The calculated IC50 (50 percent inhibitory capacity) for nevirapine and BMS806 using this method was 50nM and 30nM, respectively.

  Conclusion: SCR HIV-1 virions are replicable only for one cycle. Using these virions can improve the safety of HIV researches. Herein, we optimized the assaying of HIV induced cytopathic effects by using SCR HIV-1 (NL4-3) virions. The accuracy of this method was accepted by quantifying the anti-HIV-1 effects of nevirapine and BMS806 by (SCR) HIV-1 virions.

  Background & Objectives: Visual impairment included mild visual loss to total blindness that depends on the definitions different results achieved in various studies in all over the world. These kinds of studies will be helpful for social and health problems because some of the causes of blindness are preventable and curable at early stages.

  Methods: This study is a cross-sectional study. In this study, 300 patients older than 40 years with CF visual acuity or less had been surveyed, and information related to the patients recorded in questionnaires. The patients diagnosed by expert physician and recorded data were analyzedby descriptive statistical methods.

  Results: 57% of patients were male and 43% were female, and 41% were urban and 59% rural. The most common cause of visual impairment regarding to the definitions in this study was cataract (57%) and primary glaucoma (16%), uveitis (61%), corneal disease (6%), ARMD (4.33%), diabetic retinopathy (4%) and refraction disorder (myopia) were respectively after cataract and central retinal artery obstruction with 0.66% had the less prevalence. At all, retinal disease with 15% of prevalence was in third place of the major causes of visual impairment. Cataract was the cause of 43.9% of visual impairment in men and 74.4% in women. Glaucoma (24.6%) was the second cause in men and third common cause of visual impairment in women with 4.7% and comparing with men has lower prevalence.

  Conclussion: In this study cataract and glaucoma were the main causes of visual impairment, same as global studies, respectively. In this study prevalence of glaucoma in men was more than the prevalence in women and appears to be related to the fact that women are more sensitive to their health status comparing with men and they go to ophthalmologists sooner than men. With knowing that glaucoma will be controllable with appropriate treatments at the early stage and irreversible visual loss will be prevented.

  Background & Objectives: Giardia duodenalis is the most common intestinal parasite with cosmopolitan distribution. This parasite has been found in the intestine of humans and other mammalian hosts including cats, dogs, cattle, sheep, deer, pigs and muskrats. It is postulated that animals maybe reservoir for human infection and viceversa. In present study, the possible genetic similarity between cat and humans Giardia and its probable zoonosis were investigated.

  Methods: Direct examination and formalin-ether concentration techniques were performed on stray and semi stray cat fecal specimens. Gradient sucrose method was applied for collection and purification of cysts and DNA extraction was performed by phenol-chloroform and CTAB (Cetyl trimethyl ammonium bromid ( methods. DNA of cysts could hardly be extracted after repeated freezing and thawing. Polymerase chain reaction (PCR) was performed for DNA amplification. In this study triosephosphate isomerase (tpi) gene was selected as a molecular marker. Two sets of primers (PM 290 and PM 924) were considered. Two restriction enzymes RsaI and AvaI were also used to determine restriction fragment length polymorphism (RFLP) for PCR fragments amplified by both primer sets.

  Results: Ten samples were positive for Giardia cysts which were examined for molecular investigation. Four cat isolates were amplified by PM 290. PCR-RFLP patterns were found to be similar to human isolates AC≠AF 069556 (subgroup of AC≠U 57897) with possibility of cross-transmission.

  Conclusion: Therefore the similarity of genomic characters of isolates of cat and human Giardia implies possibility of zoonosis and transmission of these protozoa from cat to human and vice versa.

  Background & Objectives: Coronary bifurcation lesions are important, complex lesions with different therapeutic strategies. In this study, patients with Coronary bifurcation lesions were treated and clinical results in these patients were followed during the nine-month period.

  Methods: This descriptive analytical study was performed between January 2007 to December 2008 at Tabriz Shahid Madani Cardiovascular Center. We have studied 96 patients (83 male and 13 female). Patients on the basis of one or two stents were placed in one group and the other groups were divided based on the use of Drug Eluting Stent and Bare Metal Stent. After diagnostic angiography if coronary bifurcation lesions were present based on Medina classification, appropriate angioplasty treatment was carried out. In a situations including chest pain, electrocardiographic changes or the objective evidence of ischemia and indication of angiography, appropriate diagnostic tests during follow up period were done. Clinical outcomes including acute coronary events were recorded. And result analyzed using SPSS version 16 . Chi-square ، Fisher and T tests were used to compare the relationship between variables.

  Results: In this study 86.5% was male and 13.5% female. The mean age of these patients was 56±9.9 years old. The most prevalent risk factor was HTN with 41.7% incidence and 55.2% of patient had chronic stable angina and 26% of them had history of acute myocardial infarction, 7.2% with history of PCI and 5.2% with history Of CABGS. Most prevalent site of bifurcation was ALD/diagonal with 65.5% incidence. The most prevalent complication was mild bleeding from puncture site with 10.4% and 5.2% of patients had mild hematoma. Among patients with two stents versus one stent presence of AMI presentation with CSA, ST Elevation in ECG was statistically significant. Also involvement of SB (side branch) lesions lengths at SB, kissing ballooning after implantation of two stents were statistically significant. Among patients with DES versus BMS usage of stent in RCA, LAD, lesion lengths at PMB (proximal main branch), DMP (distal main branch) and SB, procedure time, radiation dose, fluoroscopy time were statistically significant. Among two groups MACE (major acute coronary event) in two stents patient between 1-3 month and total MACE at first 6 month were statistically significant

  Conclusion: The age of patients treated with CBL was low, also more usage of BMS and stenting of BFLs with two BMS had weak results in this study but surprisingly total results of BMS and DES did not have significant difference after 9 months follow up between two groups.

  Background & Objectives : Nowadays, coronary artery disease is the most common cause of death in developed countries and in the whole world. According to the WHO reports, it will be the main cause of death in 2020. Myocardial infarction is the most common diagnosis among hospitalized patients in industrialized countries. This disease causes more mortality and morbidity than others. Coronary artery bypass grafting surgery (CABGS) is one of the common treatments for ischemic heart disease but it may have some complications. In this study we wanted to evaluate the incidence of CABGS complications in Imam Khomeini Hospital of Ardabil in the first month after CABG.

  Methods: This study was a cross sectional analytic descriptive type and performed on all of the patients underwent CABGS in Imam Khomeini Hospital during 2011-2012. All of the data from patients (like demographic, past medical history, physical exam findings, paraclinical findings and CABGS complications) were inserted in special forms after gathering, and analyzed by SPSS v.16.

  Results: In this study, 211 patients were studied. About 145 (68.72%) of them were male and 66 (31.28%) were female. Seventy patient (33.17%) were more than 70 years old. About 33.22% of patients had a history of cigarette smoking and 9.95% were opioid abused. The 34.12% of patients had hypertension (HTN) history, 40.28% diabetes mellitus (DM), 17.06% history of hyperlipidemia and 63.98% had a history of the previous MI. Chest pain was the most common complication among the patients (93.36%). According to our study the prevalence rate of post CABGS complications were: bleeding after surgery 13.27%, postoperative myocardial infection 8.05%, neurological disorders 12.32%, renal complications 2.36%, respiratory symptoms 11.37% and 34.59% for cardiovascular complications. Also the total mortality was 5 (2.36%) persons. The data analysis showed that there was a significant relationship between sex with survival status, local infection and neurological disorders, and also there was a significant relationship between age with post CABGS survival, bleeding after surgery and renal complications. There was also a significant relationship between DM and post CABGS survival, local infections and respiratory complications and between HTN and local infections.

  Conclusion: According to the results of this study, the most common post CABGS complications were cardiovascular complications, especially arrhythmias.

Background & objectives: Most of coronary angiography patients have not enough information about undergoing procedure . This lack of knowledge makes anxiety in patients and thereby changes their vital signs. There is no study regarding the effective education of patients based on their native language. This study was done to investigate the effect of video education in native language on vital signs caused by anxiety of patients undergoing coronary angiography.

Methods: This quasi experimental study was done in 2013 on 160 patients undergoing angiography in Imam Khomeini Hospital in Ardabil. Participants were divided into two groups randomly (80 in each group): case (native video education) and control groups. The sheets of hemodynamic variables were completed in determined time intervals for data collection. ANOVA with repeated measures and Chi square were used to analyze the data in SPSS13 software. P-value<0.05 was considered statistically significant.

Results: The results of repeated measures ANOVA showed significant improvement in vital sign variables except for temperature in both groups over the time (p<0.05). And there was significant difference in the mean vital sign variables in determined time intervals (p<0.05).

Conclusion: Video education in native language decreases the vital signs in coronary angiography patients. Therefore the video education especially in native language is recommended for improving vital signs before invasive procedures.

Background & objectives:  The use of supplements such as L-carnitine, optimum nutritional support and early feeding after surgery in cancer patients can be important in the prevention of cancer complications. The aim of this study was to determine the effects of early L-carnitine-rich feeding on complications of esophageal cancer surgery and duration of hospitalization.
Methods: In a clinical trial, 50 patients with esophageal cancer under surgery in two equal groups were randomly selected. Nutritional information was obtained using food record questionnaire. Basic blood samples and 24-hour urine samples were taken in order to measure the hematological parameters (like blood cell count, hemoglobin, hematocrit and blood urea) and nitrogen balance, respectively from two groups at the beginning and end of the study. Then, the intervention group received 3 g L-carnitine daily in 3 doses on the first day after the complementary operation, with a routine hospital diet at each meal, and the control group received a routine hospital diet for ten days. Data were analyzed using independent t-test, paired t-test and chi-square test.
Results: The results showed that changes in the mean BUN and nitrogen balance were significantly different after intervention between the study groups (p<0.05). Patients with early L-carnitine-rich feeding had less hospitalization time in hospital wards and were discharged earlier (p<0.05).
Conclusion:  The results of this study showed that early L-carnitine-rich feeding after surgery has probably a positive effect on the duration of hospital stay in patients with esophageal cancer.

Background & objectives: Asthma is one of the most common chronic diseases in the world and Iran. Despite appropriate treatment, recent researches indicate that asthmatic patients have poor asthma control. The aim of this study was to determine the correlation between educational level of asthmatic patients and asthma control indices.
Methods: This retrospective cross-sectional study was performed on 80 asthmatic patients admitted to Shahid Labbafinejad hospital. ESMAA questionnaire was used to collect data to assess the level of asthma control, according to ACT (Asthma Control Test) and 2016 GINA (the Global Initiative for Asthma) guidelines. Patient medication compliance was evaluated based on Morisky medication adherence scale (MMAS). ANOVA test (Regression and Pearson correlation) and Chi-Square test were used for analysis of quantitative and qualitative variables, respectively. The P - value less than 0.05 was considered statistically significant.
Results: Eighty asthmatic patients with an average age of 54.65 were entered to this study that of them 32 patients were at primary school level, 26 patients at high school level and 22 patients at university state. According to ACT test, 52.5% and 47.5% of patients were in control and uncontrolled state, respectively.
According to GINA classification, 30% of patients were in control, 45% in partially control and 25% in uncontrolled state. According to MMSA scale, 20% of patients were high adherent to medicine, 40% were moderate adherent and 40% were low adherent. In this study, there was no significant correlation between the asthma control in terms of ACT and patients' educational level. Also, there was no significant relationship between sex, asthma control and medication adherence. In addition, there was no significant relationship between educational level and drug adherence.
Conclusion: The results suggest that there was no relationship between asthma control indices and patient's educational level. Perhaps other factors, other than education, affect the asthma control indices and medication adherence which requires more studies.

Background & objectives: Chronic Obstructive Pulmonary Disease (COPD) is accompanied by systemic inflammations and is characterized by irreversible airflow limitations. Leptin is a cytokine with pre-inflammatory effect. However, there have been no studies on the effect of conjugated linoleic acid (CLA) on the serum leptin concentration in COPD patients. Therefore, the present study aimed to explore the effect of CLA on the serum leptin level, lung function and quality of life in COPD patients.
Methods: This interventional study was conducted on 90 COPD patients. The patients were randomly divided into two groups (supplement and placebo) with 45 patients per group. After obtaining written consent from the patients and recording their demographic characteristics, the spirometry was performed and COPD assessment test (CAT) score was calculated. Moreover, a fasting blood sample was collected from each of them in order to analyze their serum leptin concentration. After that, the patients in the supplement group were administered with 3.2 g/day of CLA for 6 weeks. The patients in another group received placebo. After the intervention, spirometry, CAT score calculation and blood sampling were repeated for all of the patients and the obtained results were analyzed.
Results: after the intervention, a significant decrease both in the serum leptin level and in CAT score as a quality life marker  was observed in the supplement group (p<0.05). Moreover, the FEV1 levels as a lung function test, increased significantly in the supplement group after the intervention (p<0.05). Although, the difference between the two groups was not significant.
Conclusion: The use of CLA supplement can improve COPD patients’ quality of life through decreasing the serum level of leptin in their blood.

Before describing the structure and mechanism of action of a protein, it must first be subject to purification procedure. Protein purification is a set of processes in which one or a small number of proteins are purified from a complex compound that may be a complete cell, tissue, or organism. Understanding the functions, structural properties, and interactions of the protein are directly related to the degree of purity of the protein of interest. In the purification process, the protein and non-protein parts are separated. The biggest challenge is when the protein must be separated from other proteins. The purification procedure of an unknown protein is usually depends on the size, physicochemical properties, binding affinity, and biological activity. The end product of the purification process is called protein isolate. The protein purification process usually involves filtration and one or more chromatographic steps. Chromatography is a useful method for acquiring very pure protein for using in very accurate experiments. Therefore, by purifying the desired molecule, it can be used in various industries, such as medicine.
