Abstract
Background and Aim: Cervical Cancer (CC) is the third most common malignancy in the women, the main cause of which is human papillomavirus (HPV). Both E6 and E7 oncogenes of the virus play an important role in its tumorigenesis. Today, methods available for screening CC are not capable of detecting the disease at an early stage. Therefore, it is important to identify new biomarkers for early detection of this cancer. For this purpose, in the present study, miRNAs targeting the two oncogenes E6 and E7 of human papillomavirus (types 16 and 18) were studied in CC by bioinformatics.
Methods & Materials: First, using the NCBI database, the E6 and E7 gene sequences were obtained for both human papillomavirus types 16 and 18. Then, using the miRBase and RNA22 bioinformatics databases, the most appropriate targeting miRNAs for these genes were selected.
Ethical Considerations: This study was approved by Ethics Committee of Arak University of Medical Sciences.
Results: Based on the P obtained from bioinformatics databases, miRNA including miR-92a-5p (P=7.51e-2), miR-195-3p (P=2.24e-1), miR-34a-5p (P=2.73e-1) and miR-155-5p (P=4.95e-2) were introduced for the two genes E6 and E7.
Conclusion: Results from bioinformatics studies revealed that of the four miRNAs identified, miR-155-5p and miR-92a-5p are probably the targeting miRNAs specific for the E6 and E7 genes, respectively. Therefore, it seems that these miRNAs can be a suitable candidate for in vitro studies in CC patients.

Abstract
Background and Aim: One of the problems of children with Autism Spectrum Disorder (ASD) is behavioral excesses resistance to many educational and rehabilitation programs. Parent-mediated behavioral interventions seem to be effective in overcoming these problems. However, these methods are not well-introduced. The purpose of this study is to systematically review these studies and their primary and secondary outcomes, and finally analyze the components.
Methods & Materials: This study was a systematic review. The search included SID, Magiran, Medline, PubMed, Springer, Science Direct, Online Library, and PsycINFO. We reviewed The articles published between 2000 and 2017 about parent-mediated behavioral interventions on behavioral excesses in autistic children.
Ethical Considerations: This study with ethical code IR.SBU.ICBS.97/1013 was approved by the Biological Research Department of Shahid Beheshti University.
Results: The findings of 9 studies indicated positive effects of parent-mediated behavioral intervention on behavioral excesses, including repetitive behaviors, irritability (including tantrums, aggression, and self-injurious behaviors), echolalia, and destructive behaviors (preliminary results). Also, these interventions improved the adaptive behaviors in autistic children, and parental functions such as self-efficacy, parental style, psychological problems (secondary results). Components of the therapeutic program included the type of consequence-based interventions (such as response interruption and redirection), antecedent-based interventions A (visual cue and daily schedules), antecedent-based interventions B (such as enriching environment with play). Three articles had medium certainty of the evidence, and 6 had high certainty of evidence.
Conclusion: The results of this study indicated the positive effect of parent-mediated behavioral intervention on behavioral excesses in children with ASD. Future studies should emphasize the comprehensiveness of all the effective components in the parent-mediated behavioral intervention and the feasibility of the intervention in various contexts. It is suggested that parent-mediated interventions be implemented on behavioral excesses in children with ASD in Iran.

Abstract
Background and Aim: Ankle injuries are among the most common musculoskeletal injuries in sports, accounting for 10% to 15% of all injuries. Since controlling pain and inflammation in ankle sprains is one of the main goals of treatment, we decided to compare the therapeutic effects of Cheleh daghi Herbal ointment with a common therapeutic gel such as piroxicam.
Methods & Materials: This study was performed as a double-blinded clinical trial for 6 months from January 2019 to August 2019. After referral, all patients completed the consent form, and the patient's details and study variables were recorded by the evaluator in the research form. To measure joint inflammation, we measured the ankle with a meter tape in the ankle area (cm) and recorded. A goniometer was also used to measure the degree of ankle movements. The symptoms of ankle ecchymosis were also checked by physical examination and observation and recorded in the checklist. Statistical analysis was performed in SPSS V. 18 using statistical tests (the Mann-Whitney U test, the Chi-square, and the independent t-test).
Ethical Considerations: The Research Ethics Committee of Arak University of Medical Sciences approved the study (Code: IR.ARAKMU.REC.1396.55) and registered by the Clinical Trial (Code: IRCT2017071720258N53).
Results: The Mean±SD age in the control group was 34.2±8.6 years, and in the case group was 35.4±8.9 years. There was no statistically significant difference according to the Mann-Whitney U test (P<0.05). Also, the Mean±SD height in the control group was 1.7±0.12 m and in the case group was 1.72±0.11 m. The results also showed a statistically significant difference between the two groups studied before and after the intervention regarding the mean indicators of pain, swelling, and inflammation around the joints (P<0.05).
Conclusion: The results of our study showed that Cheleh daghi Herbal ointment for 3 weeks could be more effective in reducing local pain and inflammation than piroxicam gel treatment.

Abstract
Background and Aim: The COVID-19 pandemic is capable of severely affecting the mental health of health care workers, who are at the forefront of this crisis; while the official staff of health organizations is facing the same danger. Therefore, monitoring awareness and other mental health issues to understand the mediating factors and awareness of appropriate interventions is a necessary priority. Therefore, the purpose of this study was to compare the level of knowledge, attitude, and practice of medical and administrative staff in facing the COVID-19 virus.
Methods & Materials: This cross-sectional descriptive study was performed on 160 medical and administrative staff of Jahrom hospitals in 2020. Demographic information questionnaire and researcher-made questionnaire of knowledge, attitude and practice of medical personnel about coronavirus (Covid 19) were used to collect information. Data were analyzed using SPSS software version 21 and descriptive and inferential statistical tests.
Results: 65% of subjects were women and the rest were men. In most of the answers given to each item in both groups, the medical and administrative staff’s answers were close to each other. In the case of the statement "I am more likely to get a corona", 54.4% of the medical staff chose the strongly agreed option, while this percentage is 16.5% for the administrative staff. This indicates that the medical staff is very afraid of getting COVID-19. According to the results, the mean knowledge scores of the medical staff (with an average of 94.35) were significantly higher than the administrative staff (with an average of 87.75) (t=5.96, p<0.001). But the performance of administrative staff (with an average of 93.14) is significantly higher than medical staff (with an average of 87.17) (t=-2.710, p=0.007). No significant difference was observed between the mean scores of the attitude scores of both groups (p=0.438).
Conclusion: The results of this study showed that the level of awareness in the face of corona virus in the administrative staff is significantly lower than the medical staff, but the administrative staff has a better performance in facing of the corona virus than the medical staff. It seems that educational measures are necessary to increase the awareness of these people.

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 & Aim: This study aimed at comparing efficacy of cognitive behavioral therapy, Zolpidem 10 mg, and waiting list group on illness perception and sleep efficiency in individuals with chronic insomnia disorder.
Materials & Methods: Participants included 74 (female = 43) individuals with chronic insomnia disorder who were recruited from 2018 December to 2020 February by purposive sampling (inclusive & exclusive criteria). Then, patients randomly allocated to one of the three conditions, including cognitive behavioral therapy (N=25), pharmacotherapy (Zolpidem 10 mg.; N=29), and the waiting list (N=20). All patients were assessed three times at pretreatment, post-treatment, and 3-month follow-up by the Persian version of Brief Illness Perception Questionnaire and Sleep Efficiency Index. The data were analyzed by mixed analysis of variance with Bonferroni post-hoc test and repeated measure analysis of variance.
Ethical Considerations: All stages of the research have been carried after taking supervising and approving of Kharazmi University's ethics in research committee.
Findings: The patients who received cognitive behavioral therapy compared to patients in waiting list group, obtained significantly lower scores in illness perception and sleep efficiency during post-treatment and 3-month follow-up. Efficacy of pharmacotherapy only observed during post-treatment but there were no significant differences between pharmacotherapy and waiting list patients during 3-month follow-up.
Conclusion: Cognitive behavioral therapy for insomnia reduced significantly illness perceptions and sleep efficiency during 3 months. All the treatment gains remain stable even 3 months later treatment ends. In addition, not receiving any treatment in waiting list and gradually discontinued the treatment in pharmacotherapy group leads to decreasing of sleep efficiency and increasing of illness perception.

Abstract
Background and Aim: Genetic and environmental factors are known to be related to the development of childhood Eczema. We aimed to assess the ecological factors associated with the prevalence of Eczema among children using the ISAAC questionnaire.
Methods & Materials: A total of 1600 primary school girls and boys were selected and examined by multistage random sampling in this cross-sectional study. Data were collected and completed using the International ISAAC Questionnaire, including demographic questions and risk factors through interviews with parents, especially the student’s mother. The data were analyzed in SPSS v. 19 software using the Chi-square test and multiple logistic regression.
Ethical Considerations: This study was approved by the Ethics Committee of Zahedan University of Medical Sciences (Code: REC.1397.481).
Results: The prevalence of current Eczema was 10.4% (95%CI: 8.9-11.9). Co-morbidity with Asthma and Rhinitis was 82.8% and 74.5%, respectively. In multiple logistic regression models, history of allergies in family members (OR: 2.35, 95%CI: 1.53-3.59), father snoring (OR: 3.00, CI95%: 1.98-4.55), Keeping any animal in (OR: 1.6, 95%CI: 1.002-2.58), family size (OR: 0.85, 95%CI: 0.68-0.95), exposure to tobacco smoke at home (OR: 2.84, 95%CI: 1.18-6.81), showed a significant relationship with the occurrence of students’ Eczema.
Conclusion: Exposure to tobacco smoke at home, keeping any animal at home are effective factors in the prevalence of Eczema in children. By eliminating these factors, the prevalence of this disease can be reduced. However, the mothers have the most crucial role in screening and early diagnosis of Eczema in school children regarding determinants in this study. According to the results of this study, it is suggested that parents’ education, especially mothers, be emphasized by paying attention to these favorable factors.

Abstract
Background and Aim: Acquisition skill in sentence producing is one of the criteria for speech development. By developing and increasing the age, we are witnessing the emergence of compound sentences in speech. Clinical treatments for language disorders in Iran are mostly based on the experiences of Speech Language Therapists or in accordance with English language norms. We need to examine how the length of utterance and compound sentences develop in Persian. The study aimed to report the development of compound sentences and Mean Length of Utterance (MLU) for a Persian-speaking child from 15 to 34 months.
Methods & Materials: In this longitudinal case report, based on Developmental-Descriptive model, MLU and emergence of simple compound sentences of a Persian speaking girl sampled and described from 15 to 34 months by daily scripting. R software version 4.0.2 was used for data analysis. Correlation of age with linguistic variables through Pearson correlation coefficient was evaluated.
Ethical Considerations: In this paper, the principles of publication ethics were considered.
Results: At the age of 21 months and 13 days, the child uttered her first simple two-word sentence, and at the age of 26 months and 29 days, she used a four-word compound sentence. With the emergence of compound sentences, the increase in the MLU has gained considerable speed. In a few days, we see the addition of a unit to the length of the sentence (word). There was a significant relationship between the MLU and age (r=0.925, P=0.001), Mean length of sentence and number of words in Persian speaking child (r=0.910, P=0.002) and total number of words and age (r=0.928, P<0.001).
Conclusion: Although several longitudinal studies have been conducted on the development of MLU and number of words in other languages, similar studies are rare in Persian. It is important to conduct studies of this type in order to make cross-linguistic comparisons and to study the linguistic universality and language specificity. By increasing age, we see an increase in the number of words in a child's vocabulary, the emergence of compound sentences, and an increase MLU. At 27 to 28 months, there is a dramatic change in the development expressive language as the compound sentences appear. It seems that emergence of compound sentences in the language output, also plays a significant role in increasing the MLU and can be considered in clinical language assessments.

Abstract
Background and Aim PBK is a mitogen-activated protein kinase (MAPKK) among MEK1/2 and MEK7 and can phosphorylate P38, JNK, and ERK in many cellular functions. The E2F transcription factor family also belongs to a class of cellular regulators acting as oncogenes and tumor suppressors. This study aims to investigate the expression of PBK and E2F7 in the early stages of colorectal cancer (CRC) compared to advanced stages based on the experimental and TCGA (The Cancer Genome Atlas) database.
Methods & Materials A total of 32 tissue samples of patients with CRC with the approval of a pathobiologist were collected according to the examination and criteria reported from different stages. After RNA extraction and cDNA synthesis, the RT-qPCR technique was used to evaluate the expression of the desired genes in the study groups. A receiver operating characteristic (ROC) curve analysis was also used to determine the ability of each of the selected genes to differentiate the two populations: stage I+II and stage III+IV.
Ethical Considerations In all stages of this research, codes of ethics of research and publication were observed.
Results In this study, it was shown that the expression of PBK and E2F7 significantly increased in stage I+II samples compared to stage III+IV. These data were confirmed by laboratory results and information extracted from the TCGA database. Also, based on the area under curve obtained from the ROC curves, these two genes are significantly distinguishable between stage I+II and III+IV populations in CRC.
Conclusion According to the results of this study, PBK and E2F7 genes are good markers in the diagnosis of CRC.

Abstract
Background and Aim Recently, a myokine called irisin has been discovered that affects glucose level, obesity, metabolism and glucose homeostasis by browning of white adipose tissue and heat production. This study aims to evaluate the effect of four weeks of ginger supplementation followed by acute eccentric and concentric training on irisin and insulin levels, insulin resistance index, and lipid profile of young women with obesity.
Methods & Materials This is a randomized clinical trial. Participants were 50 young women (BMI >30 kg/m2, age: 24.86±2.87 years, height: 159.66±4.20 cm, and weight: 87.42±4.61 kg). After measuring their maximum oxygen consumption, they were randomly divided into five groups, two groups of supplementation, two groups of placebo, and one control group. The training protocol consisted of two sessions of acute eccentric and concentric activity. The supplementation groups consumed 2 g of ginger powder daily for 4 weeks. Blood samples were collected before and immediately after each activity. Data were analyzed using dependent t-test and one-way analysis of variance (ANOVA).
Ethical Considerations This study was registered by Iranian Registry of Clinical Trials (Code: IRCT201104246178N1) and was approved by the ethics committee of Ilam University of Medical Sciences (Code: IR.MEDILAM.REC.1395.192).
Results The irisin and insulin levels between increased and the glucose level decreased significantly in the supplementation groups (P<0.05). The change in insulin resistance index was not significantly different among the study groups (P>0.05). Based on the results of one-way ANOVA, triglyceride and low-density lipoprotein levels decreased significantly (P<0.05), but the high-density lipoprotein level showed no significant difference (P<0.05). The total cholesterol level was not significantly different in terms of exercise type (P> 0.05) but was significantly different in terms of supplementation type (P<0.05).
Conclusion Long-term consumption of ginger along with regular exercise can be an effective method for lowering glucose level and causing favorable changes in irisin level, insulin resistance, and lipid profile in young women with obesity.

Abstract
Background and Aim The efflux pump in Pseudomonas aeruginosa inhibits the effect of ciprofloxacin by releasing quinolones out of the cell. It is important to find compounds to inactivate or inhibit its activity to continue using the antibiotics. The present study was done to investigate using sertraline as an efflux pump inhibitor in P. aeruginosa to reduce antibiotic resistance.
Methods & Materials P. aeruginosa strains were isolated from clinical sources and identified by routine microbiological methods. Resistance of the isolates to ciprofloxacin was evaluated by Kirby–Bauer test. Resistance breakdown was investigated by adding sertraline to the Moller Hinton agar medium and determining the zone of inhibition of ciprofloxacin. Minimum inhibitory concentration (MIC) by microplate dilution method and Minimum bactericidal concentration (MBC) by culture and MTT method were done for the isolates and ATCC 27853. The presence of the efflux pump was evaluated by the phenotypic method using sertraline and serial dilution method of the liquid medium in a microplate, on ciprofloxacin-resistant strains. The presence of the producing gene of this pump was determined by the genotyping method in resistant strains by performing PCR. The standard PAO1 strain of P. aeruginosa was used as a positive control.
Ethical Considerations This study was approved by the Ethics Committee of the Faculty of Medical Sciences of Islamic Azad University, Brojerd Branch (Code: IR.IAU.B.REC.1401.011).
Results Based on Kirby–Bauer test results, three strains were considered resistant to ciprofloxacin. MIC of drug-resistant strains was between 32 and 64 mg/ml and MBC was between 16 and 32 mg/ml. By performing electrophoresis on the PCR products, it was determined that the tested strains contained the mexA gene encoding the efflux pump. In the agar medium without sertraline, the zone of inhibition around the ciprofloxacin disc was zero, but after adding sertraline, the diameter of the halo increased to 25 mm. The minimum inhibitory concentration of ciprofloxacin in the isolates before adding 25 µg of sertraline was 128 µg/ml and after adding sertraline, it was 4 µg/ml.
Conclusion It was concluded that sertraline inhibited the efficiency of the efflux pump in resistant P. aeruginosa isolates and reduced ciprofloxacin resistance.

Abstract
Introduction: Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract. Several methods like Multiplex or real-time PCR, ELISA, and Agglutination are used to identify these bacteria. However, normally rapid, cost effective and easy diagnostic methods such as agglutination test is recommended. In Iran, positive control antiserums used in diagnostic kits work based on polyvalent agglutination and are against O and H antigens. The purpose of this research was to produce specific anti-sera against O and H antigens for using in agglutination and ELISA kits.
Methods: New Zealand white rabbits were immunized by intravenous injections of inactivated bacterial O and H antigens adjusted to a cell density equivalent to a turbidity of a McFarland number 3 standard. Serum collection was performed 7 days after the last injection. Collected Antisera were tested with positive human specimens as well as cross-reaction antibodies. Absorption method was used to obtain specific anti-sera against O and H antigens. Produced Anti-O and Anti-H antibodies were mixed with bacterial H and O antigens respectively and incubated for 1 hours in 37˚c. The Mixture was centrifuged and the supernatant was collected. Furthermore, in order to use these antisera in specific kits such as ELISA, Immunofluorescence etc., purification methods like Ammonium sulphate precipitation, tangential Flow Filtration and Chromatography were performed. This study was approved by the ethics committee of Pasteur Institute of Iran (Code: IR.PII.REC.1399.006).
Results: Results of agglutination test before and after adsorption showed cross-reaction before adsorption and no cross-reaction with H and O antigens with monospecific antisera against O and H after adsorption, respectively. Moreover, high quality and quantity of mono-specific antibody was obtained after purification.
Conclusions: Serum-based assays are recommended for the timely diagnosis of the disease since these assays are specific, sensitive, inexpensive, and rapid. Therefore, the produced antiserum in the present research can be used in primary screening of salmonella infections based on agglutination tests which are cost effective and simple. In addition, purified anti-sera can be used in the development of ELISA and Immunofluorescence assays.

Abstract
Introduction: stress is an important criterion affecting personality on a general and minor level.
Aim: The present study aimed to assess the mediating role of stress in two diagnostic criteria of personality disorder, personality functioning (criterion A) and pathological personality traits (criterion B).
Method: The research method was descriptive-correlational. The statistical population was students studying at the University of Kurdistan in the academic year 2020-2021. By the available sampling method, 313 (50.08% of women) completed online PID-5, LPFS and PSS-14 questionnaires. Data were analyzed by structural equation modelling and using AMOS software version 24 and SPSS.
Results: The result of the direct path shows the mediating role of stress on personality detachment (0.85) and antagonism (0.88) traits. However, psychoticism, negative affectivity and disinhibition traits do not play a mediating role. In general, there was a positive relationship between stress and personality functioning (0.45) and personality traits (0.27).
Conclusion: The undeniable impact of stress on both personality functioning and personality traits is apparent. Broadly speaking, stress influences the alternative model of personality disorders, encompassing criteria A and B.
Keywords: Stress, Personality traits, Level of personality functioning, AMPD, ICD-11

Abstract
Introduction: Today, disabled sports have become one of the most important categories in the world of sports. In the meantime, exercising the blind and visually impaired is essential. Therefore, the present study aimed to examine the effect of clothing weight on the range of lower limb muscle activities during the execution of archery skills in blind people.
Methods: The current research is semi-experimental and laboratory-type. The statistical sample of the present study included 30 blind boys from Ardabil City who were selected purposefully and voluntarily. The subjects were randomly divided into two groups. The shooting target was placed at a distance of 10 meters from the subject. A two-way analysis of variance and a t-test at a significance level of 0.05 were used for statistical analysis of the data.
Results: According to the obtained results, the effect of the time factor on the electrical activity of the vastus medialis muscle when releasing the bowstring was statistically significant. The impact of the group factor on the electrical activity of the tibialis anterior muscle when releasing the bowstring had a statistically significant difference. Also, the effect of the group factor when taking the bow in the rectus femoris muscle and biceps muscle had a statistically significant difference.
Conclusions: Finally, according to all the obtained results, it can be said that probably using shooting clothes by affecting the electrical activity of the muscles of the lower limbs can improve balance during shooting, which can be one of the influential reasons, and become efficient in the success of archers.

Abstract
Introduction: The present study findings aimed to investigate the effect of exercises based on the American National Academy of Sports Medicine principles (NASM) on walking kinetics in piriformis syndrome in middle-aged men.
Methods: The current research was semi-experimental and laboratory-type. The statistical sample of the present study was 30 men with piriformis syndrome. Subjects were equally and randomly placed in two intervention and control groups. The intervention group performed NASM exercises for eight weeks. Before and after the exercises, the ground reaction force variables were measured using a Bartek force plate device with a sampling rate of 1000 Hz. Kinetic data were smoothed using a fourth-order Butterworth filter with a frequency cutoff of 20 Hz. For statistical analysis, analysis of variance and paired T-test were utilized at the significance level of P < 0.05.
Results: The findings of the present study showed that the effect of time on the FxHC and FyHC components at the peak of the forces and the FyHC component at the time of reaching the peak of the ground reaction force increased in the post-test compared to the pre-test. P > 0.025;
d = 0.64 - 0.96. The effect of the time factor in the FyPO component at the peak of the ground reaction force in the post-test was less than the pre-test (P < 0.025; d = 1.64-0.96). The interaction effect of the time × group in the FxPO component at the peak of the force and the FzHC component at the time of reaching the peak of the ground reaction force had a significant difference (P < 0.048; d = 0.87-0.83).
Conclusions: The NASM exercises used in this research can have a clinical and therapeutic effect that can reduce damage to the lower limbs and improve the quality of walking in people with piriformis syndrome.

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.
