Abstract
Introduction: Seizure due to fever is the most prevalent neurological condition in children aged 6 to 60 months. A child's seizure can cause significant distress for parents, particularly the mother. Anxiety control and the well-being of the mother are crucial elements in managing child seizures.
Methods: In this clinical trial, 70 mothers with children experiencing febrile convulsions were divided into two groups: an experimental group and a control group. The division was done using an available sampling method. The mothers in the experimental group received an intervention based on Orem's self-care model, while the mothers in the control group received the usual care. Mothers' anxiety was assessed one day after the child's hospitalization and again three weeks later using the Spielberger questionnaire. The data was analyzed using descriptive statistics, Chi-square test, Fisher's test, and analysis of covariance in SPSS software version 25.
Results: The study showed that after one day of hospitalization, the anxiety score of mothers in the test group was 101.68, compared to 106.25 in the control group. Three weeks later, the test group's anxiety score decreased to 68.97, while the control group's score was 96.34. Importantly, the decrease in the test group was statistically significant compared to the control group (P = 0.000).
Conclusions: Engaging in self-care activities results in a decrease in maternal anxiety. Hence, it is recommended to employ this approach when caring for children who are hospitalized.

Abstract
Introduction: Urinary tract infection (UTI) is one of the most important and common infections in children. The aim of this study was to investigate the frequency of qnrB and qnrS genes in Escherichia coli and Klebsiella pneumoniae isolated from urinary tract infections of children in 17 Shahrivar Hospital in Rasht.
Materials and methods: In this descriptive cross-sectional study, 49 strains of Escherichia coli and Klebsiella pneumoniae were isolated from 17 Shahrivar Hospital in Rasht and identified using biochemical methods. Sensitivity and resistance of strains to antibiotics were determined by Kirby Bohr and dilution broth methods. PCR method was used to evaluate the frequency of qnrS and qnrB genes in isolates.
Results: In this study, the highest resistance was observed in piperacillin (81.5%) and cefazolin (88.9%) isolates from Escherichia coli and in Klebsiella pneumoniae (cefazolin (90.9%) and amoxicillin (95.5%) isolates from 49 Isolated, 73.4% had qnrB gene and 97.9% had qnrS gene.
Conclusion: It seems that one of the reasons for increasing multidrug resistance in hospital isolates of urinary tract infection (UTI) in Rasht is the increased transfer of plasmid genes between these isolates.

Abstract
Background and Aim: Diabetes is a type of metabolic disease and one of the most common endocrine diseases. Oxidative stress and inflammation play an important role in the development and progression of diabetes. mTOR signaling pathway play an important role in glucose homeostasis and proliferation of pancreatic beta cells. In the present study, the therapeutic effects of p-cymene on oxidative stress markers and expression of the mTOR gene in diabetic male Wistar rats were investigated.
Materials and Methods: Diabetes was induced by injecting 55 mg/kg body weight of streptozotocin. Biochemical analyses of pancreatic tissue and real-time PCR were done to investigate the effects of metformin (55 mg/kg body weight) and p-cymene (25, 50, and 100 mg/kg body weight) on the activities of catalase and glutathione peroxidase enzymes and mTOR gene expression.
Findings: Streptozotocin decreased catalase and glutathione peroxidase enzymes and decreased the expression of the mTOR gene in pancreatic tissue. Treatment with metformin or p-cymene improved the activities of catalase and glutathione peroxidase enzymes and the expression of the mTOR gene in a dose-independent manner.
Conclusion: Results indicate that p-cymene has antioxidant properties and can regulate the mTOR signaling pathway. Therefore, p-cymene may be effective for the treatment of diabetes alone or in combination with metformin.

Abstract
Introduction: In today’s world, with the expansion of electronic technologies and equipment generating electromagnetic fields, humans and other living organisms are continuously exposed to these fields. This exposure can have significant biological effects on the growth and function of living organisms. This study aimed to evaluate the effects of alternating magnetic fields with different intensities and frequencies on the growth of Escherichia coli (E. coli), a Gram-negative bacterium, and Staphylococcus aureus (S. aureus), a Gram-positive bacterium.
Methods: This study investigated the effects of alternating magnetic fields with intensities of 1 and 2 millitesla and frequencies of 50, 75, 100, and 150 Hz on the growth of Escherichia coli and Staphylococcus aureus. The standard plate counting technique was used for this purpose. Samples were incubated at 37°C for 24 hours, and the number of colonies was counted as colony-forming units per milliliter (CFU/ml).
Results: The results showed that the number of Escherichia coli colonies significantly increased under the influence of magnetic fields compared to the control group (P < 0.05). In contrast, the number of Staphylococcus aureus colonies significantly decreased after exposure to the magnetic field (P < 0.05).
Conclusions: The results of this study indicate that alternating magnetic fields can have different effects on the growth of various bacteria. According to these findings, a decrease in the number of colonies was observed in Staphylococcus aureus due to the magnetic field, while an increase in the number of colonies was observed in Escherichia coli. These findings could be used in the development of new methods for controlling bacterial growth and in biotechnological applications.
