In the Corona crisis, we face a wide range of thoughts, feelings, attitudes, and behaviors on social media. This data contains valuable information for responding to the crisis by the people and administrators. The goal of this study is to identify the characteristics of messages that lead to different emotional polarities. This study aims to investigate the information posted by Twitter, Instagram, and Telegram users and news related to the COVID-19 pandemic in Iran. The data extracted from social networks are focused on the period of January 21, to April 29, 2020, which were shared in Iran and in Persian. It should be noted that the data set and their labels were published by the Cognitive Sciences and Technologies Council (CSTC) in Iran. In this work, the content of each post was pre-processed. Pre-processing was performed by removing stop words, normalizing the words, tokenizing, and stemming. The emotion labels were based on plutchik’s model and included joy, trust, fear, surprise, sadness, anticipation, anger, disgust, stress, and other emotions. In this study, clustering algorithms were used to analyze social media posts. We applied a two-stage clustering method. The proposed clustering algorithm was a combination of self-organized neural network and K-means algorithms. According to our proposed algorithm, the data were clustered through SOM at first, the results of which provided the initial cluster centers for the K-means algorithm. Implementations were built in Python version 3.7 and MATLAB R2015a. Hazm Tools was used for pre-processing data, and clustering was done in MATLAB. The Davies-Bouldin clustering evaluation was applied to find the optimal number of clusters. This measure was calculated for the number of clusters in the range of 2-50 in the two-stage clustering method. The results showed that the optimal number of clusters was ten. Analysis of the results showed that posts related to health and culture with negative polarity led to negative emotions such as fear, hatred, sadness, and anger. Messages about people's emotional and improper functioning have led to feelings of sadness, fear, and stress, and reduced hope in society. The results revealed a strong correlation between anger and disgust. Also, a positive correlation between fear, stress, and sadness was observed. In order to reduce the negative feelings and to create a sense of trust in the authorities, we suggest clarifying about the corona pandemic

Diabetes is one of the most prevalent diseases in the world with its side effects, for instance in reproductive system. Probiotics are beneficial microorganisms that have preventive and therapeutic effects. The present study aimed to evaluate the effect of probiotics Bifidobacterium lactis and Lactobacillus casei on sperm maturation in streptozotocin-induced diabetic rats.

In this experimental study, 35 male Wistar rats were divided into five groups: control, diabetic (type 1), diabetic rats treated with B.lactis and L.casei and a mixture of both probiotics. Diabetic groups were injected intraperitoneally with streptozotocin (60mg/kg). Probiotics were administered for 35 days. At the end of treatment, blood glucose levels, epididymal weight and sperm maturation were evaluated. The percentage of histone-protamine replacement was evaluated by aniline blue staining.

In the present study, blood glucose level in the diabetic group was significantly increased compared to the control group (P<0.001), however, the diabetic groups treated with Lactobacillus casei and Bifidobacterium lactis showed a significant decrease compared to the diabetic group (P<0.001).
The percentage of immature sperms was significantly increased in diabetic rats compared to the control group (P<0.001), and there was a significant increase in probiotic treatment groups compared with diabetic group (P<0.05).

Probiotics B. lactis and L. casei have a positive effect on lowering blood glucose and improving sperm maturation in diabetic rats.

Giving birth to a child with cleft lip and palate, as a crisis, can jeopardize the physical and mental health of parents, especially mothers, and affect their function.Therefore, the present study was conducted to investigate the effect of happiness program on performance in the mothers of children with cleft lip and palate.
In this semi experimental study, 64 mothers of children with cleft lip and palate referring healthcare team in Isfahan University of Medical Sciences, were enrolled by simple random sampling, and the patients’ referring and assigned to two groups of control and intervention. Then, the program of happiness training was implemented within 10 sessions of two hours each and performance Questionnaire were filled out prior to and two months after the last session. The data were analyzed by descriptive and analytical statistics consisting of paired t test, independent t test, chi-square and Mann-Whitney in SPSS 20.
Findings: Mean age of the mothers in intervention and control groups was 33.3±6.3 and 33.5±5.8 years, respectively, and Mean age of the children in intervention and control groups was 6.34±3.37 and 5.03±3.36 years. No significant differences in demographic variables between the two groups (P > 0.05). No significant differences in mean score of performance domains in the two groups before training (P > 0.05). However after 2 months a significant difference in mean score of performance domains was observed between two groups (P Given the effect of happiness program in promoting mothers performance for children with cleft lip and palate, this program can be used in healthcare centers to empower mothers and enhance performance in taking care of children.

Incidence of asthma in adolescents leads to variations in family status, roles and interaction with peers for them, which could be a source of stress and psychological tensions in them. Therefore, the present study was conducted to investigate the effect of Orem’s self-care model on perceived stress in adolescents with asthma.
In this semi-experimental study conducted from April 2013 to February 2014, 64 asthmatic adolescents referring Shariati Hospital, Isfahan were enrolled by simple random sampling and the patients were assigned to two groups of control and intervention. Then, Orem’s self-care model-based training was implemented throughout eight sessions of two hours each and the Cohen Perceived Stress Scale was administered to both groups prior to and two months after the completion of the training. The data were analyzed by descriptive and analytical statistics consisting of paired t-test, independent t-test, Chi-square and Mann-Whitney using SPSS Version 20.
Mean age of the participants was 14.15±3.12 years in the intervention group and 15.21±3.09 years in the control groups. 68.8% and 59.4% of the participants were male in the intervention and control groups, respectively. Independent t-test indicated a significant difference in the mean scores of perceived stress in the intervention (25.46±5.31) and control groups (28.90±5.27) after the training. Also, the result of paired t-test indicated a significant difference in the mean score of perceived stress between before (29.18±5.27) and after (25.46±5.31) training.
As the training based on Orem’s model had a positive effect on declining perceived stress in asthmatic adolescents, continuation of using these training interventions could contribute to ultimately achieving positive outcomes in health functions of these patients.

Acquisition of chronic diseases such as asthma leads to psychological, mental and physical complications in adolescents, and hence their self-esteem may be compromised. Therefore, the present study was conducted to assess the effect of Orem’s self-care model on self-esteem of adolescents with asthma.
This semi-experimental study enrolled 64 asthmatic adolescents referred to Shariati Hospital, Isfahan. Subjects were assigned to two groups of control and intervention consecutively. Then, the self-care training program was conducted according to Orem’s self-care model in eight two-hour sessions based on self-care needs, and self-esteem was measured in the two groups prior to and two months after the last training session. The data were collected by a questionnaire of demographic characteristics and the Coopersmith Self-Esteem Inventories (CSEI) and analyzed by SPSS version 20.
Independent t-test showed a significant difference in the mean score of self-esteem between the intervention and control groups after the training (P0.05).
Regarding the effect of Orem’s self-care model on self-esteem of adolescents with asthma, we recommend the use of this model as a care intervention in healthcare centers to promote adolescents’ health.
