Introduction: Prostate cancer is the most common type of malignant cancer among men and is known as one of the leading causes of cancer mortality in men. The complexity of diagnostic procedures such as mass biopsy has made new diagnostic strategies for prostate cancer, such as MRI imaging, a research priority in recent years. Methods: In this applied-descriptive study, a four steps method for diagnosing prostate cancer through MR image is presented. In the first step, the destructive effect of noise on the input images by using two-dimensional wavelet transform and histogram equalization is reduced. In the second step, the black hole optimization algorithm is used for segmentation of the input image based on the multilevel threshold technique. By doing this, the suspicious areas are identified in the image and in the third step, the features of each target area are extracted. In the fourth step, a combination of three learning algorithms, including: artificial neural network, decision and support vector machine is used to diagnose prostate cancer. Results: The effectiveness of the proposed method in diagnosing prostate cancer has been evaluated from various aspects and its performance has been compared with other learning models. Based on the results, the proposed method can diagnose prostate cancer through MRI images with an average accuracy of 99%. Discussion & Conclusion: The proposed method uses a combination of image processing, optimization and machine learning techniques to achieve this goal. Compared with other models, this proposed method was of the highest accuracy.

Introduction: The Corona Virus Anxiety Scale (CAS) is a widely used tool with high diagnostic power in the field of corona anxiety diagnosis, but so far no research in Iran has examined the internal structure of this scale, so research in this field seems necessary. Method: The present study is a descriptive-analytical study that was conducted in 2021. The statistical population of this study was all adults living in Isfahan, of whom 409 (342 females and 67 males) responded to the Corona Anxiety Scale by available sampling method. According to the existing conditions, the scale was prepared online and published in cyberspace, and those who were interested completed the scale. In order to analyze the data, exploratory factor analysis, confirmatory factor analysis and AMOS and SPSS software were used. Results: The results of exploratory analysis confirmed the single-factor nature of this scale. The results of confirmatory factor analysis showed that this scale has good construct validity and fit model. This scale also had a high internal consistency (Cronbach's affinity coefficient = 0.859) Conclusion: The Coronavirus Anxiety Scale has a good validity in the Iranian population and can be used to assess coronavirus anxiety in this population.

Background and Objectives Empathy plays a social role in interpersonal relationships, including interactions between doctors and patients. This study aims to investigate the level of empathy in students Ahvaz Jundishapur University of Medical Sciences (AJUMS) and its relationship with age, sex, and religiosity. Subjects and Methods In this cross-sectional descriptive study, participants were 361 AJUMS students, who were selected using a convenience sampling method in 2020. Jefferson scale of empathy and Glock & Stark religiosity scale were used to collect data. Data were analyzed using an independent t-test, Pearson correlation test, and linear regression. Results The mean total empathy score of students was 106.42±14.82, and their mean total religiosity score was 57.04±14.19. A statistically significant relationship was observed only between empathy and the emotions dimension of religiosity (r=0.125, P=0.018). No significant relationship was observed between empathy and the total score of religiosity and its other dimensions. The mean empathy score in female students was significantly higher than in male students (109.15 vs. 103.02, P˂0.001). Regression analysis results showed that the emotions dimension of religiosity, age, and sex were able to predict the level of empathy in students. Conclusion The empathy in AJUMS students is at a relatively favorable level, and has a positive significant correlation with the emotions dimension of religiosity in them. It is recommended to develop plans to strengthen the empathy of medical students and include an educational course in their curriculum so that they be able to improve the mental and spiritual health of patients.

Background: Due to the fact that in the Iranian health information seeking literature, a questionnaire to examine the factors affecting the online health information seeking behavior of students and their health beliefs, was not found, the present study designed a questionnaire for this purpose, and approved its validity and reliability using exploratory and confirmatory factors analysis. Materials and Methods: The statistical population of the present study consisted of all students studying in all educational levels in public and private universities of Ahvaz during year 2019, the total number of which was 46054 people. According to Cochran's formula, 600 students were selected for the research sample. The instrument used in the present study was a questionnaire. The questionnaire was a combination of 36-item questionnaire base on Mo, Sheen and Cohen and Deng, Liu and Hinz research questionnaires. The validity of the questionnaire was assessed by three methods: the use of scientific articles, factor analysis and its reliability calculated by use of Cronbach's alpha coefficient. Data analysis was performed using SPSS and LISREL software. Results: By performing explanatory factor analysis, the variables affecting online search for health information were categorized and renamed into ten factors: Trust in quality and efficiency, Useful intention, Self-efficacy, Cognitive values, Perceived severity, Perceived anxiety, Perceived sensitivity, Perceived barriers, Individual health beliefs, and Social values. Then these factors were investigated using confirmatory factor analysis. Conclusion: Examination of the standardized coefficients in the obtained structural model showed that almost all factor loads have the desired value.

Background and Objectives In recent years, flavonoids such as quercetin have been considered as new anticancer drugs. The mechanisms of action of quercetin include cell cycle arrest, inhabitation of cell proliferation, and induction of apoptosis. This study aims to reduce quercetin’s side effects by increasing MCF-7 breast cancer cells’ sensitivity to this drug and facilitating the cytotoxic effects of quercetin at lower concentrations. Subjects and Methods In this study, the MTT assay was used to determine the concentration that reduced the cell viability by 50% (i.e. lethal concentration 50 or LC50). Then, the expression of the DNA fragmentation factor-45 (DFF45) and some genes in the apoptosis pathway (caspase3, p53, BAX, BCL-2, AIF), the autophagy pathway (LC3, ATG5, Beclin, DRAM) and the AKT/mTOR pathway (AKT1, mTOR, and PTEN), in cells treated with siRNA, quercetin, and quercetin+siRNA using the real-time PCR. Results According to the results of MTT assay, the LC50 value for quercetin was determined 220 μM. The results indicated the initiation of cell death through autophagy pathways. The combined treatment (quercetin+siRNA) increased the mechanism of cancer cell death more than the quercetin treatment alone. Conclusion One of the regulating pathways of apoptosis is forcing the inhibitory effect of DFF45 on DFF40/CAD nuclease. Down regulation of DFF45, along with quercetin administration, can lead to induction of breast cancer cell death which can be a novel technique for the treatment of breast cancer.

Background and Objectives Despite many studies on the new Coronavirus disease 2019 (COVID-19), there is still a rate of disease mortality, which has made researchers to focus more on finding successful antiviral drugs. In this regard, small molecule inhibitors have been suggested for their higher safety, lower toxicity, and cost-effectiveness. In this study, we applied virtual screening and docking analysis to identify the prospective inhibitors of 3CL protease and ACE-2 receptors Subjects and Methods In this study, 1,600 natural compounds were assessed by virtual screening. The ligands with a high affinity to bind to active site residues of target proteins were identified using the glide docking method and then were included in the induced-fit docking analysis in Schrödinger-Maestro software. Results The found compounds such as Theaflavin and Delphinidin had a high affinity to bind to the receptors. They had higher binding energy and a potent inhibitory effect compared to common drugs such as chloroquine. Conclusion The introduced natural compounds can be used to suppress COVID-19. The results may help develop new drugs or formulations to combat COVID-19; however, clinical trials are needed to examine the potential of these small molecules alone or in combination with other medical procedures.

In this regard, small molecule inhibitors have been suggested for their higher safety, lower toxicity, and cost-effectiveness. In this study, we applied virtual screening and docking analysis to identify the prospective inhibitors of 3CL protease and ACE-2 receptors Subjects and Methods In this study, 1,600 natural compounds were assessed by virtual screening. The ligands with a high affinity to bind to active site residues of target proteins were identified using the glide docking method and then were included in the induced-fit docking analysis in Schrödinger-Maestro software. Results The found compounds such as Theaflavin and Delphinidin had a high affinity to bind to the receptors. They had higher binding energy and a potent inhibitory effect compared to common drugs such as chloroquine. Conclusion The introduced natural compounds can be used to suppress COVID-19.

Background and Objectives The use of stem cells for skin wound healing is still facing serious challenges. This study aims to determine the effectiveness of human adipose tissue-derived stem cells (ADSCs) spray in histologically improving skin wounds in male diabetic rats. Subjects and Methods In this experimental study, mesenchymal stem cells were isolated from adipose tissue and cultured and characterized by evaluating the expression of specific CD markers. Microbial contamination in samples was assessed before treatment. Then, 18 male Wistar rats were divided into control and treatment groups. Diabetes was induced by a single injection of streptozotocin. Then, wounds with a diameter of 0.8 cm were created in the back of the rats. The ADSCs were sprayed on the wound area in the treatment group. Wound healing was assessed on days 7, 14, and 21 after treatment using visual observation and histopathological examination. The data were analyzed using ANOVA. Results Wound closure was accelerated on days 7, 14 and 21 in the treatment group compared to the control group. Histological examination showed that the skin thickness, angiogenesis, and epithelialization were higher in the treatment group on days 7, 14, and 21 compared to the control group. Conclusion The spray of ADSCs on the wound area can accelerate the healing process and can be used for skin wound repair.
