Abstract
Background and Objectives: Currently, diabetes is one of the leading causes of death in the world. According to several factors diagnosis of this disease is complex and prone to human error. This study aimed to analyze the risk of having diabetes based on laboratory information, life style and, family history with the help of machine learning algorithms. When the model is trained properly, people can examine their risk of having diabetes.
Material and Methods: To classify patients, by using Python, eight different machine learning algorithms (Logistic Regression, Nearest Neighbor, Decision Tree, Random Forest, Support Vector Machine, Naive Bayesian, Neural Network and Gradient Boosting) were analysed. were evaluated by accuracy, sensitivity, specificity and ROC curve parameters.
Results: The model based on the gradient boosting algorithm showed the best performance with a prediction accuracy of %95.50.
Conclusion: In the future, this model can be used for diagnosis diabete. The basis of this study is to do more research and develop models such as other learning machine algorithms.

Abstract
Background and Objective: Human development is influenced by genetic, environmental, and social factors whose foundation is formed from infancy and childhood. Preterm birth and low birth weight are important issues that can affect the development and threaten the public health.
The aim of this study was to investigate the effect of early exercise interventions on gross motor skills of children with preterm birth aged 3 to 6 years.
Material and Methods: In this Experimental study, 30 children with average (2066 ±354g) were selected from among the preterm infants (32 to 37 weeks less than 2500 g) admitted to NICU ward. They were divided into two groups (experimental group n=15 and control group n=15 children).To evaluate the gross motor skills of children, the second version of the Peabody developmental motor scale was used. The results were analyzed by SPSS using ANCOVA test (p≤0.05).
Results: The results of this study showed that early interventions can have a positive effect on the gross motor skills of these children and the participants in the experimental group were able to obtain higher scores than the control group after participating in the training program.
Conclusion: The results showed that training interventions have a significant effect on both stability and locomotion skills.

Abstract
One of the major challenges in the field of tissue engineering is the production of scaffolding in nano-scale. The study of structural-functional connections in pathological and normal tissues with biologically active alternatives or engineered materials has been developed. Extracellular Matrix (ECM) is a suitable environment consisting of gelatin, elastin and collagen types I, II and III, etc., which are provided to cells for wound healing, embryonic development, cell growth and organogenesis, and. They also play a role in transmitting structural integrity and overall strength to tissues. In tissues, ECM manufacturers are structurally 50 to 500 nm in diameter; nanotechnology must be used to create scaffolds or ECM analogues. Recent advances in nanotechnology have led to the development of ECM-engineered analogues in various ways. To date, three self-assembly, phase separation and electrospinning techniques have been developed to activate nanofiber scaffolds. With these advances and the construction of a "biomimetic" environment, engineered tissue or scaffolding is now possible for a variety of tissues. This study will discuss the three existing methods for creating Tissue engineering scaffolds that are able to mimic new tissue, as well as the discovery of materials for use in scaffolding.

Abstract
Background: Esophageal cancer is one of the most common cancers worldwide. Because this disease is usually diagnosed in advanced stages, its treatment is challenging and the survival rate of patients is relatively low. One of the parts that is disturbed in the tumor tissue of esophageal cancer is the tight connections between cells. Claudin-4 (CLDN-4) is one of the tight junction regulatory proteins whose changes are involved in cancer formation. In this systematic review, we examine the changes in CLDN-4 and the factors that affect its level in samples and cell lines related to esophageal cancer.
Methods: Scopus, PubMed, and Web of Science databases were searched for articles that examined CLDN-4 gene and protein expression in patients with esophageal cancer or cell lines related to esophageal cancer. A number of 202 manuscripts were obtained in the beginning, and after screening and applying the inclusion and exclusion criteria, six studies remained.
Results: Six studies, including 596 patients and seven cell lines related to esophageal tissues, were included in this systematic review. The studies were related to Japan, South Korea, China, and Finland. In these studies, the level of CLDN-4 in cancer samples related to esophageal cancer and their location in esophageal tissue cells have been examined.
Conclusion: In summary, it can be concluded that the change in the level of CLDN-4 in the tumor tissues of esophageal cancer altered the tight junctions from the normal state in the normal esophageal tissues, leading to a change in normal barrier function. However, considering the conflicting results in the reports, more studies are needed to accurately interpret the role of CLDN-4 in esophageal cancer.

Abstract
Background: Mental health is significantly influenced by parenting styles, and undesirable parental authority styles can have detrimental effects on children’s mental health. Addressing mental health and its contributing factors is essential for improving individuals' personal and social lives. On the other hand, research findings on the relationship between parental authority styles and mental health have yielded conflicting results. Therefore, the present study was conducted to determine the relationship between parental authority styles and the mental health of nursing and midwifery students.
Methods: This cross-sectional, descriptive-analytical study was conducted on 435 nursing and midwifery students using a census method. The research instruments included a demographic information form, Buri’s Parental Authority Questionnaire (PAQ), and Goldberg and Hillier’s General Health Questionnaire (GHQ). Questionnaires were completed virtually via Google Docs. Data were analyzed using descriptive statistics and Pearson's correlation coefficient with SPSS software, and a significance level of P < 0.05 was considered.
Results: The mean age of the participating students was 24.71 ± 5.90 years. Most of the students surveyed were female (75.9%) and undergraduate (75.9%). The mean scores for the permissive, authoritarian, and authoritative parenting styles, and for general health, were 21.80 ± 4.64, 21.33 ± 5.64, 24.93 ± 4.92, and 19.22 ± 7.07, respectively. There was a significant and direct correlation between overall public health and the permissive parenting style (r = 0.14, p = 0.003). The correlation between the authoritative parenting style and students' mental health was inverse; however, this finding was not statistically significant (r = −0.05, p = 0.26).
Conclusion: The research results underscore the influence of parental authority styles on students' mental health. It is suggested that university counselors who provide counseling services to young adults consider the influence of parental authority styles on the diagnosis, etiology, and treatment of their mental and behavioral disorders, and take measures to assess the type of parental authority style.
