Abstract
Abstract
Background: Breast cancer is the most common cancer in women. It has been proven the association of cause of this disease with changes in several genes. One of the pathways associated with breast cancer is the folate reuptake pathway. The key enzyme of this pathway is coded by the TYMS gene. MicroRNAs control the expression of genes by binding to their regulatory regions. In this study, we evaluated changes in the regulatory region of TYMS gene with demographic characteristics (including the grade of cancer and metastasis) in breast cancer patients.
Materials and Methods: In this study, the regulatory region of TYMS gene was investigated using related bioinformatics software. After collecting cancerous samples and DNA extraction from blood samples of normal and patients, change in the miRNA binding region by digestion with NlaIII enzyme was assayed.
Results: Bioinformatics studies showed that the restriction site of some of the endonuclease enzymes in the 3'-UTR of the TYMS gene is related to the binding region of miRNAs, including Hsa-miR-433-3p. The results indicated the correctness of the genomic purification process, the PCR and enzymatic digestion reaction. In this study, in the regulatory region, CC homozygote, AC heterozygote and AA mutant homozygote variant had differences with control group (OR: 1.3465, %95 CI: 0.7275 to 2.4923, p<0.05). Also, the association of AA genotypes with metastasis and high grade of the patients was confirmed statistically.
Conclusion: Studies have shown that some of polymorphisms in the key genes involved in cancer are directly related to their diagnosis and treatment process, and given the importance of timely diagnosis of cancer, the achievement of diagnostic biomarkers in breast cancer in the early stages will be important. Probably, the nucleotide change at the site of the microRNA binding site could be used as a diagnostic biomarker for degree of tumor progression.

Abstract
Background and Aim: In this study, the effect of Myrtus extracts on 25 methicillin resistant Staphylococcus aureus (MRSA) and Escherichia coli ESBL strains isolated from patients were compared by two methods.
Materials and Methods: 15 methicillin-resistant Staphylococcus aureus (MRSA) and 10 Escherichia coli ESBL isolates were used in this study. Fresh Leaves of Myrtus were collected from the herbal medicine farm. Extraction was performed using a reflux distillation. The effect of concentrations 0.195-100 micrograms per ml of Myrtus extract on clinical isolates was analyzed in disk diffusion method compared with micro broth dilution method and with MTT in 545 nm on an ELISA reader apparatus.
Findings: Inhibition zone diameter for the minimum effective concentration of 50 micrograms per milliliter in all isolates of ESBL and MRSA were as 8±1 mm and 11±1. Minimum Inhibitory Concentration (MIC) was 6.25mic/ml and Minimum Bactericidal Concentration (MBC) was determined 12.5mic/ml for E. coli ESBL. Furthermore, the amounts for MIC and MBC was determined as 12.5 and 25 mic/ml, respectively for Staphylococcus aureus.
Conclusion: The results of this study showed compliance of two methods in evaluation of drug-resistant clinical isolates. It was proved that the disk diffusion method could be determining range of effective concentration but micro broth method determines the effective concentration carefully. It is recommended that results obtained from disk diffusion not to be basis for final decisions in traditional medicine studies. Bacterial behavior in the broth and determination of the point of death greatly increases the accuracy of the results.

Abstract
Background and Aim: The aim of this study was to evaluate the success rate and complications of Ahmed Glaucoma Valve (AGV) insertion during a follow up of at least 5 years.
Materials and Methods: In this retrospective case series study, patients with 5 years of follow up after AGV insertion were enrolled. Success was defined as intraocular pressure (IOP) < 21 mm Hg (criterion A) and IOP < 16 mm Hg (criterion B), with at least 20% reduction in IOP, either with no medication (complete success) or with no more than preoperative medication (qualified success). Cumulative success was defined as sum of qualified and complete success.
Findings: This study included 40 eyes of 40 patients with mean age of 40.63± 22.91years, (range 1 to 88). Cumulative survival success rates were 90%, 73% at 1 and 5 years after surgery according to criterion A and 42%, 25% based on criterion B with the median survival time of 60 months and 22.36 months, respectively. Complications were observed in 4 eyes of 4 patients (10%) and included wound dehiscence, choroidal detachment, encapsulated bleb and lid retraction. There were not any early complications such as hypotonia or hyphema.
Conclusion: The present study was one of the largest series that reported the long-term outcome of AGV implantation in Asian patients with refractory glaucoma, and showed the wide difference of success rate between criterion A and B.

Abstract
Background and Aim: Low-volume, high-intensity interval training (HIT) increase skeletal muscle aerobic capacity, yet little is known about the potential mechanisms in improvement of this adaptability. The purpose of present study was to examine the effect of four weeks of HIT on peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) and vascular endothelial growth factor (VEGF) protein contents in skeletal muscle of active men.
Materials and Methods: Eight active male students voluntarily and purposefully participated in this study. One week before the experiment started; subjects were familiar with protocol of research. Needle biopsy samples vastus lateralis were obtained 48 h before training and 72 h after the final training session. HIT protocol consisted of 11-15 bouts of 1 min cycling at ∼85-90% of reserve heart rate separated by 1 min of active recovery between each, 3 sessions per week for 4 weeks. Variables were measured by ELISA. All data were analyzed using paired t-test and at the level of significance of p ≤ 0.05.
Findings: Results of study showed the four weeks of HIT lead to significant increase in PGC-1α and VEGF (p < 0.001).
Conclusion: Our findings suggest that activation of VEGF from PGC-1α pathway is part of cellular-molecular mechanisms of high-intensity interval training. So, probably angiogenesis in skeletal muscle is one of the most important factors in improving of aerobic performance, which requires more studies. |

Abstract
Background and Aim: Excessive fat accumulation is one of the most important mechanisms of type 2 diabetes and insulin resistance. Accordingly, in this study, we will examine the effect of caloric restriction on lipid coat proteins that prevent lipolysis of the adipose tissue.
Materials and Methods: In this study, 30 adult male Sprague-Dawley rats (200 ± 20 weight) were used. First, rats were divided into 2 groups (standard and high-calorie diet). After 8 weeks, the high-calorie diet group was randomly assigned to two subgroups: caloric restriction and high-fat diet. Finally, the amount of perilipin 1 and 5 genes expression evaluated by Pcr and insulin resistance evaluated by HOMA index.
Findings: The weight and insulin resistance of the high-fat diet group was significantly higher than the standard and calorie restriction group (p≤0.005). Insulin resistance was not significantly different between the caloric restriction and standard group (p = 0.394). The expression of perilipin 1 in the adipose tissue of the high-fat diet was significantly higher than the caloric restriction group (p ≤0.005). The expression of perilipin 1 gene in skeletal muscle in the high-fat diet group was significantly higher than the calorie restriction and standard diet groups (p≤0.005). The calorie restriction group had more perilipin 5 expressions than the high-fat diet and the standard group (p ≤0.005).
Conclusion: The caloric restriction may be due to the effect on lipid coat proteins and, as a result, a decrease in fat accumulation, that it can prevent insulin resistance.

Abstract
Background and Aim Oxidative stress is the main factor in the development and progression of diabetes and its related complications. There is growing evidence that antioxidants supplementation can improve oxidative stress induced in diabetes. The present investigation was conducted to study the effects of Coenzyme Q10 (CoQ10) on the Oxidative Stress Index (OSI) in diabetic rats.
Methods and Materials A total of 30 male rats were divided into five groups: saline, sesame oil (as a vehicle), CoQ10-treated (10 mg/kg/day), diabetic (induced with streptozotocin: 55 mg/kg), and CoQ10-treated diabetic (10 mg/kg/d). Then, we measured the Malondialdehyde (MDA), Total Oxidant Status (TOS), and Total Antioxidant Capacity (TAC) levels in the rats’ liver homogenate. Additionally, the OSI was calculated.
Ethical Considerations The Research Ethics Committee of Arak University of Medical Sciences approved this study (Code: IR.ARAKMU.REC.1397.119).
Results results showed a significant decrease in the level of liver MDA (P=0.022), TOS (P=0.03), and OSI (P=0.028) in the CoQ10-treated diabetic group compared to the diabetic rats. No significant change was observed in the total thiol group (P=0.25) and TAC (P=0.77) level in diabetic rats’ livers treated with CoQ10 compared to diabetic rats.

Abstract
Background and Aim recombinant DNA technique is a powerful and appropriate method for the production of protein biopolymers with specificity in amino acid sequence and spatial chemistry. Elastin-Like Polypeptide (ELP) is a biocompatible, biodegradable and non-immunological biopolymer used in various biotechnology studies. The ELP tag is a cheap, fast and non-chromatographic technique for purifying target proteins. In this study, pET expression vector was designed for the combination of ELP gene sequences and target recombinant protein in order to produce recombinant fusion protein with the ELP tag.
Methods & Materials MOD gene was transformed to E. coli-BL21 (DE3) cells after designing and synthesis among the XbaI and XhoI restriction sites in the pET-32a (+) vector of the clone. Then, colonies were isolated based on plasmid size and examined by cutting using restriction enzymes. The final recombinant colonies was verified using polymerase chain reaction method and DNA sequencing.
Ethical Considerations The Research Ethics Committee of Arak University of Medical Sciences approved all ethical considerations ofworking on laboratory animals (Code: 92-146-11).
Results Replacing the MOD sequence in the pET-32a vector (+) eliminated the components expressing the fusion tags (Thioredoxin, Histidine, and S-tag), the identification site of protease enzyme (tobacco etch virus), and multiple cloning site. In addition, it added specific restriction enzyme identification sequences of ELP gene and target gene. As a result, in the optimized pET-MODvector, 466 nucleotides reduced in size and the secondary structure was improved.
Conclusion Considering the improvement of spatial structure and reduction of pET-MOD vector size, as well as the possibility of the fusion of recombinant protein with the ELP tag, it is possible to use this vector for ELPyation of the target protein.

Abstract
Background and Aim: recent years, increase in extended-spectrum β-lactamases (ESBLs) producing Escherichia coli has led to limitations of treatment options. This study aimed to find the frequency of blaTEM and blaPER genes among ESBL producing urinary isolates of E. coli and detect their resistance pattern.
Methods & Materials: From January 2016 to February 2017, 972 urine samples from patients suspected of having urinary tract infections in three main hospitals and laboratories in Karaj were collected. Bacterial identification, antimicrobial susceptibility and ESBL production were performed according to the standard guidelines. Polymerase chain reaction was used for the detection of TEM and PER -lactamases.
Ethical Considerations: This study was approved by the Research Ethics Committee of Islamic Azad University of Tehran Medical Branch (Code: IR.IAU.TMU.REC.1396.274).
Results: Out of 972 samples, 500 cases were culture-positive for E. coli. Thirty-six percent (n =180) of the isolates were determined as ESBL-producer. Among ESBL positive isolates, the most susceptibility was observed in amikacin and imipenem (80 and 60% respectively). Resistance to trimethoprim/sulfamethoxazole,ciprofloxacin, tetracycline and gentamicin was 92.7%, 78.9%, 66.1% and 57.8%, respectively. All ESBL producers exhibited multidrug resistance. Among the ESBL-positive isolates, blaTEM gene was detected in 44.72% (n=85) of the isolates, but the blaPER gene was not found in any of the isolates.
Conclusion: The prevalence of multidrug resistant ESBLs producing uropatogenic E. coli is high. Continues monitoring of ESBL producers and their resistance patterns can help to reduce the spread of such resistant strains in the community.

Abstract
Background and Aim: The adherence of diabetic patients to the recommended treatment regimens is among the major challenges in diabetes control. Dietary adherence is low in pregnant women with gestational diabetes. Non-compliance can reduce the beneficial effects of treatment, symptoms, and signs, increase complications, or even cause death. Therefore, further research on the determinants of follow-up behaviors is essential.
Methods & Materials: This was a descriptive-analytical study. In total, 260 women with gestational diabetes treated with diet referring to healthcare centers, and Imam Reza (AS), Ghaem, and Umm Al-Banin Hospitals in Mashhad City, Iran participated in this research. The study subjects were selected using convenience, multistage, class, and cluster sampling methods. The required data were collected using a demographic and pregnancy profile questionnaire and a researcher-made questionnaire of adherence to the treatment regimen. The obtained data were analyzed by inferential statists and regression tests in SPSS v. 16.
Ethical Considerations: This study was registered with ethics code of IR.MUMS.NURSE.REC.1397.091 in the ethics committee of Mashhad University of Medical Sciences.
Results: The regression analysis results indicated that dietary adherence, blood glucose monitoring, and exercise adherence scores presented a significant and positive effect on the total treatment adherence score (P<0.001). Furthermore, education (P=0.044), unwanted (P=0.006), or unplanned pregnancy (P=0.21) provided a positive and significant effect on the overall score of treatment adherence. Women with a history of diabetes in first-degree relatives (P=0.010) and those with a history of miscarriage (P=0.021) obtained higher scores of total treatment adherence.
Conclusion: According to the present study findings, some demographic and pregnancy characteristics can affect the rate of adherence to the treatment regimen in women with gestational diabetes. Healthcare providers need to pay attention to the impact of these factors in improving adherence to patients’ treatment regimens.

Abstract
Background and Aim: The protein encoded by the SGO1 gene is a member of the shugoshin family of proteins and protects the centromere during mitosis. lncRNAs are non-coding RNA with 200 nucleotides lengths, i.e., involved in regulating gene expression. The current study aimed to evaluate the expression of SGO1 and SGO1-AS1 in different stages of disease progression; we also compared their expression pattern in tumor tissues with healthy tissues in colorectal cancer patients.
Methods & Materials: In total, 40 tissue samples of patients with colorectal cancer were reported according to the examination and criteria with the approval of a pathologist. Besides, 40 normal tissues were sampled from a completely healthy part of the intestine of the same patients. After RNA extraction and cDNA synthesis, the Real-time RT-PCR technique was used to evaluate the expression of the desired genes in the study groups. ROC curve analysis was also used to determine the ability of each selected gene to diagnose the disease.
Ethical Considerations: This study was approved by the Ethics Committee of Shahrekord Azad University (Code: IR.IAU.SHKREC.1398.020).
Results The obtained data suggested that SGO1 significantly decreased in the colorectal cancer tumor samples (P<0.001) and SGO1-AS1 LncRNA significantly increased expression, compared to adjacent healthy tissues. Additionally, in the age group of below 60 years, compared to the age group of over 60 years, SGO1 expression increased and SGO1-AS1 expression decreased. Based on the AUC obtained from the ROC diagram, it was found that the SGO1 gene with AUC=0.8041 and SGO1-AS1 with AUC=0.6364 could significantly distinguish a healthy population from patients with colorectal cancer.
Conclusion: According to the collected results, SGO1 -AS1 and SGO1 were significantly reduced and increased in tumor tissue, respectively; however, only the SGO1 gene was introduced as a good marker for diagnosing colorectal cancer.

Abstract
Background and Aim: In addition to free radicals such as Nitric Oxide (NO), inflammation is one of the most important pathophysiological causes of peritonitis. Over thousands of years, Nigella Sativa (NS) and Silybum Marianum (SM) are two plants known for their anti-oxidant and anti-inflammatory properties. However, the effect of its compound is unclear. Thus, in this study, we evaluated the anti-inflammatory effect of NS and SM extracts and their combination on inflammatory diseases like thioglycollate peritoneal.
Methods & Materials: Alcoholic extracts of SM and NS were obtained by the soxhlet method. Male Balb/C mice were divided into 5 groups and gavage orally for 14 days with SM, NS, the mixture of extracts of these two, DMSO 30% as the control group, and dexamethasone as the positive control group. The safety profile and acute toxicity in mice were assessed. On day 10, acute peritonitis was induced by thioglycollate 3%. Finally, the total anti-oxidant power and NO concentration were measured by FRAP and Griess method, respectively, in the serum of treated mice.
Ethical Considerations: All experimental process was performed following the guidelines according to the Animal Ethics Committee of Arak University of Medical Sciences (IR.ARAKMU.REC.1397.359).
Results: Acute toxicity test showed no significant changes in weight and physical appearance of the mice. However, the extract and their mixture decreased NO level significantly (P=0.000) in serum. Also, the mixture significantly increased total anti-oxidant power (P=0.015).
Conclusion: Results showed that the SM and NS extract mixture demonstrated anti-inflammatory activity, inhibiting inflammatory mediators such as NO and increasing anti-oxidant power, thus supporting its therapeutic potential in slowing down inflammatory processes in inflammation disorders.

Abstract
Background and Aim: Tamoxifen is a group of drugs of selective estrogen receptor modulators, and is one of the drugs effective in the prevention and treatment of some cancers (such as breast cancer). In this study, the interaction of tamoxifen with DNA is investigated experimentally. Also, the electronic structure (at atomic scale) of the molecular system of tamoxifen was theoretically investigated, using atom in molecule (AIM) theory.
Methods & Materials: First, in the experimental section of this study, the interaction of Tamoxifen with DNA were investigated by UV-ViS technique and hydrodynamic method (Viscometry). In addition, the analysis of the experimental results shows the obvious effect of concentration on the mechanism of how the tamoxifen molecule binds to DNA. Then, in the theoretical part of this research, using computational biophysical chemistry methods, some properties of tamoxifen molecular system, such as electronic Density of States (DOS), boundary orbital’s energy (HOMO/LUMO), Electrostatic Potential Energy (EPS) and electronic contour maps of the electron density and its Laplacian, will be calculated.
Ethical Considerations: This article is a meta-analysis with animal sample.
Results: Result of the UV-ViS spectroscopy technique and viscometry indicated hyperchromism and hypochromism effect. In addition, the result were depend on the concentration of the drug and affected the kind of binding of Tamoxifen to DNA. the analysis of computational studies on the drug tamoxifen suggests that the mechanism of the local charge/energy distribution in the molecular system of tamoxifen plays an important role in how this drug binds to DNA.
Conclusion: Based on the experimental results of UV-ViS technique and viscometry, as well as the electronic/vibrational properties of the tamoxifen molecular system, it was defined that the Tamoxifen interacts significantly with all the binding sites of DNA.

Treatment efficacy was evaluated by echocardiography after the treatment.
Ethical Considerations: This study was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1396.265).
Results: Of the total participants 37.5% (female 25) were girls. Gestational age ranges from 29 to 36 weeks. The average birth weight was 1639±616 gr and the minimum of weight 750 gr. the mean gestational age was 30.4±4.0 weeks. After the first dose of ibuprofen, closure of PDA was observed in 32 patients (80%), PDA closed in eight patients (20%) with to repeat course ibuprofen. There was no significant relationship between the frequency of ibuprofen use with gestational age (P=0.06), birth weight (P=0.08), type of delivery (P=0.068) and multiple births (P=0.061).
Conclusion: Most LBW neonate with PDA responded to using the first course of ibuprofen. extremely, all LBW infants responded to the second course. it seems that ibuprofen is as effective as ibuprofen for PDA closure even in LBW infants.
