Abstract
Background: Despite advances in surgical techniques and risk management practices in recent years, wound dehiscence following abdominal laparotomy has still high prevalence. The purpose of this study is to evaluate the effect of retention sutures on wound dehiscence of emergent abdominal laparotomy.
Materials and Methods: In this randomized clinical trial study, 160 patients scheduled for emergency laparotomy for peritonitis or trauma were enrolled. Half of the patients randomly underwent retention suture and the other half underwent routine sutures. Finally, the amount of surgical wound dehiscence and complications were assessed.
Results: Three patients (3.7%) in retention group and 11 patients (13.7%) in the control group developed wound dehiscence which there was a significant difference between them (p=0.025). It was determined by multivariate logistic regression that wound dehiscence is correlated with hemodynamic status, type of trauma and injury to the abdominal organs, and sex. The incidence of wound dehiscence, early hemodynamic instability, penetrating abdominal trauma and damage to the intestines were higher in males.
Conclusion: In general, it seems that the preventive use of retention sutures in patients with multiple risk factors for postoperative wound dehiscence can be useful.

Abstract
Background: Operating room personnel are subject to occupational hazards which could lead to an increase in free radicals and develop various diseases. The aim of the present study was to determine the effect of consuming green tea on the improvement of the blood oxidative biomarkers in operating room personnel who are exposed to anesthetic gases.
Materials and Methods: This study was a before-after clinical trial which was conducted on 24 operating room personnel. They were invited to consume 4 cups of a green tea beverage, prepared from 3 g of green tea leaves in 300 mL of boiled water (at 80˚ C), daily for 8 weeks. Then, Myeloperoxidase (MPO), DNA damage, Glutathione Peroxidase (GPx), and Superoxide Dismutase (SOD) in the plasma were measured in order to evaluate the level of oxidative stress biomarkers before and after consuming green tea.
Results: Green tea consumption by operating room personnel brought about a significant increase in glutathione peroxidase and superoxide dismutase and a considerable decrease in myeloperoxidase and DNA damage.
Conclusion: According to the results of this study, green tea consumption as an antioxidant supplement by operating room personnel, who are regularly exposed to anesthetic gases, can minimize oxidative stress and DNA damage considerably. Thus, it is advisable for operating room personnel to consume green tea as a natural antioxidant supplement.

Abstract
Background: Ulcerative colitis (UC) is a chronic disease that specifically affects the mucosa of the rectum and colon. The pathogenesis of UC is not well defined, but it is proposed that genetic and environmental factors result in an aberrant immune response to a subset of commensal enteric bacteria.The aim of this study was to investigate whether miR-34b/c rs4938723 T/C polymorphism is associated with UC risk.
Materials and Methods: Blood samples were collected from 50 patients diagnosed with UC and 100 healthy control subjects. Genomic DNA was extracted from peripheral blood. Genetic variation of miR34b/c was determined by tetra-primers ARMS-PCR (amplification refractory mutation system-polymerase chain reaction). All statistical analyses were conducted using the MedCalc version 12.1.
Results: There was a significant difference in genotype and allele distributions between cases and controls. It was observed that the CT heterozygotes had a 2.29-fold increase in risk of UC (OR=2.29, 95%CI=1.08-4.82, p=0.02).
Conclusion: It is suggested that the miR34b/c (rs4938723 T>C) polymorphism may be associated with the risk of UC. However, larger studies with more patients and controls are needed to confirm this result.

Abstract
Background and Aim: Human papillomavirus (HPV) infection is a prevalent, life-threatening disease and cause of cancer among women. Therefore, in recent years, developing novel anti-HPV agents is highly regarded. The study was planned to bioinformatic screening for E1 and E2 potential inhibitors of HPV serotypes including 16,18,31,33 and 45 types from medicinal plants.
Materials and Methods: This is a descriptive-analytic study. In the first step, three-dimension structure of phytochemicals were retrieved from PubChem database and then the cell cytotoxicity and mutagenesis potential of them were evaluated. In the next step, the amino acid sequences of two key proteins of mentioned types of HPV including E1 and E2 were obtained from Uniprot database. Furthermore, the conserved and variable regions of the protein sequences were predicted using multiple sequence alignment method. Finally, the three-dimension structure of mentioned proteins was determined by homology modeling method and potential interactions of the phytochemicals with the proteins were investigated using molecular docking method through Autodock 4.2.6 software.
Findings: The results demonstrated that ursolic acid has no cytotoxicity and mutagenesis potential with appropriate physicochemical properties. Results also showed that mentioned compound had strong interaction with both E1 and E2 of all studied serotypes. Furthermore, the evaluation of ursolic acid and E1 and E2 interactions showed that amino acid is involved in conserved regions of mentioned serotypes.
Conclusion: Based on the obtained results of present study ursolic acid could be good candidate for more in vitro and in vivo studies of its anti HPV activity.

Abstract
Background and Aim Chronic Lymphocytic Leukemia (CLL) is the most commonly occurring leukemia in adults, accounting for about 30-25% of total leukemia. One of the important etiological causes of this leukemia is the disruption of the Nuclear Factor Kappa B (NF-kB) signaling pathway. The two proteins of Apoptosis-Inducing Ligand (APRIL) and B-Cell Activating Factor (BAFF) play a role in the pathogenesis of this leukemia by affecting the NF-kB signaling pathway. In this study, due to the effect of miRNAs in regulating many cellular processes, the prediction of the prominent miRNAs targeting APRIL and BAFF transcripts in B-cell CLL patients was evaluated using specific and different bioinformatics programs.
Methods & Materials Afterwards retrieving the sequences of APRIL and BAFF proteins from the NCBI website, by using several programs including miRanda, TargetScan, miRWalk, DIANA and miRDB with different algorithms, the prediction of miRNAs targeting these genes was investigated.
Ethical Considerations This study was approved by the Research Ethics Committee of Arak University of Medical Sciences.
Results Based on the scoring system of bioinformatics programs, “hsa-miR-145-5p” and “hsa-miR-185-5p” were identified as miRNAs targeting APRIL gene, while “hsa-miR-424” and “hsa-miR-497”were miRNAs targeting BAFF gene. They were suggested for the practical studies in future.
Conclusion Based on the important role of APRIL and BAFF genes in the normal process of cell death and B-cell evolution, it seems that the mi-RNAs predicted by bioinformatics programs using different algorithms can be used as a diagnostic molecular biomarker to identify B-cell CLL patients.

Abstract
Background and Aim The high use of pesticides has increased the concern about its possible harm to individual and environment health. Chronic exposure to pesticides has serious effects on different body organs even before the onset of clinical symptoms. In this study, we aim to evaluate clinical and biochemical characteristics of male workers in a pesticide production factory in Guilan province, Iran.
Methods & Materials This cross-sectional study was conducted on 99 male workers exposed to pesticide and 107 people without exposure who were employed in a pesticide production factory in Guilan and selected using a convenience sampling method in 2020. Their demographical data as well as clinical characteristics such as respiratory symptoms (cough, shortness of breath, etc.), neurological symptoms (fatigue, tremors, cramps, muscle weakness, etc.), psychological symptoms (sleep disorders, anxiety, etc.) and skin symptoms (redness, itching, etc.) were collected from the occupational health records of the workers. Finally, the biochemical parameters were compared between the two groups. Statistical analysis was performed in SPSS software, version 16.
Ethical Considerations This study was approved by the Research Ethics committee of Guilan University of Medical Science, Rasht, Iran (Code: IR.GUMS.REC.1399.632). Informed consent was obtained from all participants in this study.
Results The frequency of symptoms such as headache, itchy skin, cough, and sleep disorders was higher in the exposed group (P<0.05). Based on the biochemical findings, blood urea level, creatinine level, alkaline phosphatase, and fasting blood sugar level were significantly higher in the exposed group (P<0.05). Thrombocytosis was observed in 9.09% of exposed workers, which was higher in those with more than 11 years of work experience.
Conclusion Chronic exposure to pesticide can cause thrombosis, changes in biochemical parameters, and clinical symptoms. It is recommended that biological monitoring should be conducted in exposed workers at a shorter interval.

Abstract
Introduction: Type 2 diabetes is a non-communicable disease that imposes a significant financial burden on the healthcare system each year. Numerous studies have demonstrated the involvement of inflammatory factors in the initiation and progression of this condition. The primary goal of this study is to compare the polymorphism of the interleukin 1 receptor antagonist gene among individuals with type 2 diabetes and those in the control group.
Methods: Following approval from the Ethics Committee of Gonabad University of Medical Sciences, blood samples were collected from 100 participants at Bohlool Hospital in Gonabad. These individuals were categorized into two groups: cases (individuals with type 2 diabetes) and controls (healthy individuals). DNA extraction was carried out using the salting out method. To examine the polymorphism, the specific segment was initially amplified through PCR with designated primers and then identified via gel electrophoresis. The data were analyzed using subjected to the Chi-square test at a significance level below 5%.
Results: Findings from the polymorphism analysis revealed a notable contrast in the genotype 2/1 (P = 0.001) and 2/2 (P = 0.004) within the case group when compared to the healthy participants. Specifically, individuals with genotype 2/1 exhibited a heightened risk of developing type 2 diabetes by up to 15 times.
Conclusions: Within the examined population, the polymorphism of the interleukin 1 receptor antagonist gene substantially influenced the predisposition to type 2 diabetes, amplifying the likelihood of developing this ailment. Individuals harboring allele 2 are at an increased susceptibility to type 2 diabetes.
