Background
In the 21st century, the deadly viral disease rabies continues to claim victims. After entering the cell, the rabies virus (RABV) utilizes growth and transcription factors or certain cell proteins to evade the immune system. Focal adhesion kinase (FAK) is an essential intracellular kinase that positively interacts with the rabies phosphoprotein, which is not only a multifunctional protein with transcription and replication activity but also an interferon (IFN) antagonist, benefiting the RABV. It has been proven that heat shock protein 90 (Hsp90), a crucial cellular chaperone, along with cell division cycle 37 (Cdc37), a co-chaperone of Hsp90 that can function independently, are involved in the maturation, stabilization, and activation of the RABV. When the RABV infects the cell, it exploits FAK, Hsp90, and Cdc37 for its survival and replication.
ObjectivesThis study aims to eliminate the positive effects of FAK, Hsp90, and Cdc37 on the RABV to increase the survival time of RABV-infected cells.
MethodsWe investigated the effect of FAK inhibition with PF-573,228 and the prevention of Hsp90 or Cdc37 protein expression with shRNAs on the rabies P protein in infected cells. Techniques used in our research included MTT assay, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), and Western blot analysis.
ResultsThe results showed a robust decrease in P protein and the titer of the RABV in cells treated with PF-573,228 or transfected with Hsp90 and Cdc37 ShRNAs. However, this did not lead to the complete elimination of P protein expression, indicating that FAK, Hsp90, and Cdc37 are not the only factors the RABV uses for reproduction and survival.
ConclusionsAccording to our results, FAK has the most significant association with rabies P protein during replication, followed by Hsp90 and Cdc37, respectively.

Introduction
Self-harm is a serious health concern, and is relatively common among adolescents. The quality-of-service delivery to self-harming patients is related to the knowledge and attitude of nurses.
ObjectiveThis study aimed to determine the knowledge and attitude of emergency department (ED) nurses from northern Iran regarding the care of self-harming adolescents and find the related factors.
Materials and MethodsThis analytical cross-sectional study was conducted on 208 ED nurses with over 6 months of work experience in the ED of hospitals in Rasht, Iran. They were selected using a census sampling method. The data collection tool was a three-part questionnaire including a sociodemographic form, the attitudes towards deliberate self-harm questionnaire (ADSHQ), and Letho et al.’s knowledge scale. The collected data were analyzed using the Kolmogorov-Smirnov test, Shapiro-Wilks test, Mann-Whitney U test, multiple linear regression analysis, and the Spearman correlation test.
ResultsThe mean age of the nurses was 34.8±7.8 years, and the majority of them were female (90.9%) with a bachelor’s degree (88.5%). The mean total score of knowledge was 0.67±0.12. Nurses’ attitudes were mostly positive, and the total ADSHQ score was 3.59±0.28. The ADSHQ score was significantly different based on nurses’ age (P=0.03) and experience in caring for self-harming adolescents (P=0.033). The ADSHQ score had a positive correlation with the knowledge score (r=0.252, P=0.001). The knowledge score was significantly different based on marital status (P=0.042) and experience in caring for self-harming adolescents (P=0.016). The significant factors for the ADSHQ score in the multiple regression model were the risk factors domain of the knowledge (β=0.334, 95%CI; 1.527%, 3.367%, P=0.001), age (β=0.184, 95% CI; 0.061%, 0.323%, P=0.004) and experience in caring for self-harming adolescents (β=2.4, 95% CI; 0.340%, 4.595%, P=0.023).
ConclusionNurses’ knowledge in caring of the intentional self-harm adolescents was moderate and their attitude towards these adolescents was positive. In the EDs, it is recommended that nurses with experience dealing with self-harming adolescents be employed. Also, retraining programs should be provided to ED nurses to improve their knowledge and positive attitudes towards caring for self-harming adolescents, focusing on increasing empathy and perceived confidence.

Cellular stress, induced by diverse factors including viral infection, reactive oxygen species (ROS), hypoxia, and toxin exposure, disrupts normal cellular function. The endoplasmic reticulum (ER) is pivotal in managing cellular stress, notably through the unfolded protein response (UPR) and ER-associated degradation (ERAD) pathways. This intricate process involves a complex interplay of transcription factors and signaling molecules. During viral infection, cells activate a multifaceted antiviral response, which is specifically modulated by both the virus type and the molecular mechanisms of the host's immune system. For instance, certain viruses like Japanese encephalitis virus (JEV) exploit multiple cellular pathways for replication and propagation. Viral infection can significantly impact cellular processes like autophagy and apoptosis, either promoting or suppressing these pathways. Thus, the cellular response to viral infection represents a dynamic interplay that can either benefit the host or be exploited by the virus for its propagation. For instance, viruses within the Flaviviridae family often preserve host cell viability during early infection to enhance replication, subsequently triggering apoptosis or other cell death mechanisms to facilitate viral dissemination. This review explores the diverse responses of infected cells to various viruses, highlighting the complex molecular strategies employed by both host and pathogen.

Introduction
During the COVID-19 epidemic, the mental status of nurses and other healthcare workers was strongly influenced by environmental conditions.
ObjectiveThis study aimed to determine the association between social support and resilience with the mediating role of self-efficacy in nurses working in public hospitals.
Materials and MethodsIn this cross-sectional study, 220 nurses working in the educational and medical centers of Rasht City, Iran, in 2021 were recruited by simple random sampling. The general self-efficacy scale, multidimensional scale of perceived social support questionnaire, and Connor and Davidson resilience scale were used to collect data. The Pearson correlation coefficient test was used to investigate the linear relationship of the variables. To evaluate the fit of the proposed model, the chi-square test, degrees of freedom, goodness of fit index, Tucker-Lewis index, comparative fit index, and root mean square error of approximation were calculated. Bootstrap test was used to investigate the role of self-efficacy in the middle of social support and resilience and to assess the direct effects of variables.
ResultsThe results showed that 201 women (91.4%) and 19 men (8.6%), with a mean age of 36±8.43 years, participated in this study. Moreover, 25.5% and 74.5% of participants worked in COVID-19 or non-COVID-19 wards, respectively. Data analysis using the Bootstrap test showed that self-efficacy mediated between social support and resilience (P=0.001). Also, the study findings have shown that the direct effects of social support on resilience are significant, with a path coefficient of 0.203 (P=0.004), so when social support increases, resilience increases, too. Also, in this research, the direct path of self-efficacy on resilience was significant with a path coefficient of 0.595 (P=0.001), so when self-efficacy increases, resilience increases, too.
ConclusionsFindings of this study have shown that nurses’ self-efficacy serves as a mediator in the relationship between social support and productivity. Empirical evidence suggests that individuals who receive greater social support exhibit heightened levels of self-efficacy.

Precise diagnosis is crucial for implementing suitable and timely treatment strategies, especially when dealing with life-threatening infections like rabies. Rapid diagnosis of rabies is crucial for preventing transmission to the patient’s immediate contacts and medical staff, thereby controlling the further spread of the virus. Conventional methods for detecting rabies are either time-consuming or necessitate expensive equipment operated by trained professionals. This paper presents a novel rapid diagnostic method for rabies. This innovative approach leverages an isothermal reaction within a single platform, offering results within an hour and eliminating the need for specialized equipment. This method uses Cas13a enzyme, buffer, three guide RNAs, and a probe to detect rabies virus RNA using a lateral flow chromatography technique in samples suspected of rabies virus. After doing the test, the results are indicated by the presence of the control (C) and test (T) lines on the strip. Preliminary evaluations demonstrate that this rapid method correlates well with established diagnostic standards, showing promising sensitivity and specificity values.

استنتاجاین مطالعه نشان داد در پاندمی کووید-19، مادران باردار و شیرده، نشانه های اضطراب بیش تری نسبت به افسردگی داشتند و نشانه های افسردگی در زنان باردار بیش تر از مادران شیرده بود. این نتایج بر اهمیت پایش سلامت روان برای بهینه کردن کیفیت مراقبت پری ناتال طی اپیدمی ها/ بحران های اجتماعی تاکید می کند.
کلید واژگان: اضطراب، افسردگی، بارداری، شیردهی، کووید-19Background and purposeThe spread of COVID-19 can cause anxiety and depression and lead to adverse outcomes in perinatal period. This study aimed to evaluate anxiety and depression symptoms and associated factors in pregnant and breast feeding women during the COVID-19 pandemic.
Materials and methodsThis cross-sectional study included 450 pregnant and breast feeding women in Rasht, Iran during the second and third wave of COVID-19 (June-November 2020). Data were collected using convenience and multi-stage sampling in a teaching hospital and six healthcare centers. Anxiety and depression were evaluated by Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9, respectively. Descriptive statistics and analytical statistics, including independent t-test, Chi-square test, and logistic regression were used to analyze the data.
ResultsGeneralized anxiety was seen in 16.9% of pregnant women and 10.7% of breast feeding women (P=0.057). Expectant mothers were 6.64 times more likely to have depressive symptoms compared with breast feeding women (ORAdj=6.64, 95% CI: 2.08-21.15). Comorbid anxiety-depressive symptoms were higher in pregnant women than breast feeding women (6.2% vs. 0.9%, P=0.002). Anxiety was found to be significantly associated with an unemployed husband, having chronic diseases, thinking about COVID-19, and high-risk individuals in the family (P<0.05). Also, there was a significant relationship between depression and pregnancy, less educated husband, and high-risk individuals in the family (P< 0.05).
ConclusionIn this study, pregnant and breast feeding women showed more anxiety symptoms than depression symptoms during COVID-19. Expectant mothers were more likely to have depressive symptoms than breast feeding women. These results emphasize the importance of mental health monitoring to improve perinatal-care quality during epidemics/social crises.

Objective
This study aimed to determine prevalence of anxiety and depression and associated factors in the general population of Iran during the COVID-19 pandemic.
MethodWe conducted this web-based cross-sectional study on 5328 individuals in Iran between 17th and 29th of April 2020. Data were collected using the convenience sampling method through an anonymous online questionnaire via social media like WhatsApp and Telegram. The online survey collected data on demographic variables, COVID-19-related variables, and symptoms of anxiety and depression. Anxiety and depression were assessed using the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), respectively. Simple and multiple logistic regression analyses were performed to determine independent predictors of anxiety and depression.
ResultsThe mean GAD-7 and PHQ-9 total scores were 7.17 (SD = 5.42) and 7.80 (SD = 6.68), respectively. Prevalence of anxiety, depression, and comorbid anxiety-depression were 30.1%, 33.4%, and 22.1%, respectively. According to the adjusted analysis, anxiety was significantly associated with female gender, being young and middle-aged, being unemployed or a housewife, having chronic diseases, spending considerable time thinking about COVID-19, having family members, friends, and/or relatives infected with COVID-19, and death of family members, relatives or friends due to COVID-19. Same results were also found for depression. Furthermore, depression was associated with being single, being resident in urban area, and having high risk individual in family.
ConclusionPrevalence of anxiety and depression were considerably higher in the general population of Iran during the COVID-19 pandemic. In addition, the findings suggest that more attention needs to be paid to vulnerable groups such as women, young/middle-aged adults, the unemployed, and people with chronic disease.

Background
Apoptosis is a programmed cell death in which certain cellular components are packed into small membrane vacuoles by immune cells. Different strains of rabies virus (RABV) have their own biological features, but their effects on apoptosis have been little known. The aim of current research was to evaluate Beclin 1 effect on apoptosis in the mouse infected with the street rabies virus.
Materials and MethodsExogenous Beclin1 overexpressed by the pIRES2-EGFP-Beclin1 vector in the cortex of NMRI mice. To evaluate the apoptosis, TUNEL assay was done on brain tissues of the rabid mice.
ResultsTUNEL assay data showed that small apoptotic cells were seen in the four groups that received the vector alone or with the SRABV, but no significant changes were observed. There are no signs of apoptosis in mouse normal brain cells.
ConclusionIt was previously proven that overexpression of exogenous Beclin1 could induce autophagy but this study showed that overexpression of Beclin 1 does not cause apoptosis in rabies-infected cells.

In nursing, the communication between the nurse and the child is the core of child care. Some barriers can affect the nurse-patient relationship to have proper communication skills for child care.
ObjectiveThis study aimed to examine the correlation between communication skills and early maladaptive schemas in nurses working in pediatric wards.
Materials and MethodsThis is an analytical and correlational study. The participants were 178 nurses working in a children’s hospital in Rasht City, Iran in 2016. The data collection tool was a three-part questionnaire: A demographic form, the interpersonal communication skills scale (ASMA), and the Young Schema Questionnaire-Short Form (YSQ-SF). The collected data were analyzed using descriptive statistics and the Friedman and Spearman tests.
ResultsThe majority of nurses were younger than 30 years (80.8%), had a bachelor’s degree in nursing (89.0%), were married (65.1%), had children (54.8%), were living in urban areas (95.2%), had employment status (63.3%) and less than 15 years of work experience (46.5%). The highest mean scores of ASMA (44.12±0.53) and YSQ-SF tools (2.65±1.04) were related to general communication skills and then disconnection and rejection, respectively. The results of the Spearman correlation test showed that the overall ASMA score had significant negative correlations with early maladaptive schemas of impaired autonomy and performance (r= -0.283), impaired limits (r= -0.421), other-directedness (r= -0.303), and disconnection and rejection (r= -0.302) (P=0.0001).
ConclusionNurses who have a higher level of early maladaptive schemas showed poorer communication skills. Examining maladaptive schemas in nurses may provide appropriate strategies to improve their communication skills.

The purpose of the present study was to replace an in vitro method consistent with medical ethics criteria instead of an in vivo method. By recognizing that the potency of the rabies vaccine depends on the amount of glycoprotein antigen content and the monoclonal antibody detect the correct folding of antigen of the rabies virus, then the glycoprotein content could be represent of vaccine potency.
MethodsIn this study, we designed an immune-capture enzyme-linked immunosorbent assay (ELISA) with three antibodies (capture, primary and secondary) to determine the existent amount of viral glycoprotein in different rabies vaccines, and compared the results at the same time with measuring potency of those vaccines using the NIH method. This applied study was conducted from September 2016 to September 2018 at the Research Laboratory of the World Health Organization Collaborating Center for reference and research on rabies at the Pasteur Institute of Iran in Tehran.
ResultsThe slope of the standard line was calculated to R2=0.98 (P=0.0013). In the humans’ vaccines, the mean lied between 5.554-7.336 (SD=0.0463-0.1039) and the coefficient of variation was 0.778-2.436 (SD=0.0041-0.2724), at the same time in the animals’ vaccines the mean were 2.293-5.993 (SD=0.0041-0.2724) and the coefficient of variation was calculated 0.182-4.546. For animal vaccines the Pearson correlation coefficient is 0.99 and for the human vaccines this coefficient was 0.95. Also, the concordance correlation coefficient for animal vaccines was 0.98 and for human vaccines is 0.95, indicating a moderate to high concordance in both animals and humans vaccines.
ConclusionThe designed Immuno-capture ELISA kit had a proper acceptance criterion, intermediate precision, good linearity and robustness for measuring the glycoprotein level of the vaccine, which was directly related to the vaccine potency.

هدف از این مطالعه، القای اتوفاژی با ژن بکلین 1 و تاثیر آن در روند نکروز رده سلولی MCDK بود.مواد و روش هادر این مطالعه، القای اتوفاژی با ژن بکلین 1 در سلول های MDCK بررسی شد. سپس درصد مرگ سلولی نکروز در این سلول ها با روش فلوسایتومتری با استفاده از کیت رنگ آمیزی آنکسین V سنجیده شد. به منظور القا کردن اتوفاژی، سازه HYPERLINK «../../../../../abstract/med/21426771/» \t «_blank»Beclin1-(-)pcDNA 3.1 با استفاده از لیپوفکتامین 3000 درون رده سلولی MDCK ترنسفکت شد.نتایجدر مطالعه حاضر مشاهده شد که بیان بالای ژن بکلین1 در سلول های MDCK به القای اتوفاژی منجر می شود، همان گونه که با رنگ آمیزی شاخص اتوفاگوزومی داخل سلولی دیده شد. درصد ساختارهای LC3 مثبت در سلول های ترنسفکت شده و نشده به ترتیب 92/9 و 15/0 درصد بود. در گروه های ترنسفکت شده و کنترل، درصد مرگ سلولی نکروز، به ترتیب 66/1 و 06/0 درصد بود.نتیجه گیریتداخل بین مسیرهای اتوفاژی و نکروز ممکن است بر سرنوشت طول عمر سلول اثر داشته باشد. استراتژی های درگیر در تعدیل کردن اتوفاژی و مرگ سلولی ممکن است بر روند درمان بیماری ها موثر باشد. بنابراین دستکاری مسیرهای مرگ سلولی ممکن است حوزه های جدیدی را در استفاده های درمانی و مداخله ای ایجاد کند.کلید واژگان: اتوفاژی، بکلین 1، نکروز، فلوسایتومتریObjectiveAutophagy (self-digestion) is a highly regulated process for the degradation of damaged proteins and intracellular components. Autophagy has multifunctional roles in the protection of cellular homeostasis. Beclin1 is a key regulator molecule in autophagosome formation. Inhibition of autophagy by destruction of the Beclin 1 allele creates sensitivity to metabolic stress. Inhibition of the autophagy under conditions of nutrient deprivation in tumors resistant to apoptosis can lead to necrosis, inflammation and increased tumor growth. This study aims to assess the effect of autophagy induction on the necrosis pathway of MDCK cells.MethodsWe evaluated induction of autophagy by the Beclin1 gene in MDCK cells and assessed the percentage of necrosis cell death by flow cytometry using an Annexin V Staining kit. In order to induce autophagy, the recombinant pcDNA3.1-Beclin 1 was transfected into the MDCK cell line using lipofectamine TM 3000.ResultsOverexpression of the Beclin1 gene in MDCK cells led to induction of autophagy as seen by intracellular autophagosomal indicator LC3-II staining. There were 9.92% positive LC3 structures in transfected cells and 0.15% in untransfected cells. In the transfected and control groups, the rate of necrosis cell death was 1.66% and 0.06%, respectively.ConclusionCrosstalk between autophagy and necrosis pathways might affect the fate of the cell life span. Strategies that involve in modulation of autophagy and cell death might lead to therapeutic interventions in diseases. Therefore manipulation of cell death pathways could create new areas in therapeutic uses and interventions.Keywords: Autophagy, Beclin 1, Necrosis, MDCK cell, Flow cytometry -

Caregivers without sufficient knowledge cannot perform their responsibilities very well. This situation leads to relapse and re-hospitalization. Families experience a lot of stress facing such difficult situations which results in discomfort, tensions or despair in family members. High tensions impair family function unless the family adapt to the new situation.ObjectiveThis study aimed to determine effectiveness of stress coping skills training with psycho-educational approach among caregivers` of schizophrenic patients on family function and psychological well-being.MethodsThis is an experimental study with pretest-post test design and a control group comprising of main following variables; coping skills training with a psycho-educational approach(the independent variable) and family function and psychological well-being (two dependent variables).
The study population included 220 caregivers of patients with schizophrenia who had referred to psychiatric clinic and had a history of hospitalization. Since the number of members in a psychotherapy group should be very limited, the sample size was considered 30. Sampling was performed with convenience method. Data collection tools included Ryff Psychological Well-Being and Family Assessment Device questionnaires. The psychometrics of both questionnaires had been confirmed in Iran. Ryff assesses six main components of psychological well-being. Therefore, it has 6 subscales (each subscale contains 14 items) and 84 items. The subjects specified their level of agreement, "agree "to" disagree", in a 6-point Likert scale. To obtain a score for each subscale, the score of each item on the related subscale should be summed. The total score of all 84 items equals the total psychological well-being. The subscales include self-acceptance, positive relations with others, autonomy, environmental mastery, purposeful life and personal growth.
Family Assessment Device is a questionnaire with 60 items in domains of problem-solving, relationships, roles, effective response, effective involvement, behavior control, and general functioning. They were answered in a 4-Likert scale. In order to obtain the score of each subscale, all subscale scores have to be added then divided by number of items of each subscale. Higher scores show poor functioning. In this study, the mean score was used to compare the groups.
The researcher referred to the psychiatry clinic and specified the records of patients diagnosed with schizophrenia and had the inclusion criteria; being main caregiver, educated and living in Rasht. The families were then contacted.30 patients were randomly selected whose psychological well-being and family function score had one SD below the mean of questionnaires scores. They were placed in two experimental and control groups (15 per group). During the intervention, six subjects (3 per group) withdrew due to family problems and the disease recurrence. Again in the last session, the questionnaires were completed by the subjects. The interventions were performed twice a week for 90 minutes in twelve consecutive sessions. Homogeneity of the two groups in terms of evaluated variables was approved using ANOVA. Then, the variance-covariance analysis was used to determine the effectiveness of stress coping skill straining with psyche-educational approach on variables of family function and psychological well-being.ResultsMost of the subjects (58.3%) were women with mean age of 53.9±5.87. Majority of them (79.2%) had secondary education. Analysis of data showed that the mean score of family function in the experimental group in pretest was 183.42± 13.96 and 177.08±8.23 in the control group. The mean score of the psychological well-being was 224.58±27.03 in the experimental and 228.33± 12.01in the control group. In the posttest, the mean score of family function equaled121.83±15.59 and the control group 172.58±4.25. Moreover, in the post test the mean of psychological well-being of the experimental group and the control group were 373.33±23.96 and 242.67±7.27, respectively.
