Соотношение терминов и понятий Римского права и гражданского законодательства Российской Федерации
Authors: Хромов М.А.
Published: March 2024

Статья посвящена актуальным вопросам гражданского права России. Рассматриваются проблемы влияния норм римского права на современное гражданское право России. Римское право является образцом для законотворческой деятельности в современных условиях, многие его институты и положения являются основой современного законодательства. Использование римских норм в решении современных правовых споров придает юридическим решениям оригинальность и основывается на ценностях и принципах, разработанных и опробованных в течение многих столетий римской юриспруденцией. Автор отмечает, что Русское право в отличии от западноевропейского, заимствовало лишь идеи, вырабатывая на этой базе собственные юридические конструкции. Именно это позволяет говорить об оригинальности российского права. Делается вывод, что исследования в этой области могут быть направлены на более детальное изучение конкретных элементов римского права и их влияния на современное гражданское законодательство.

Published: March 2024

Background: Acute Lymphoid Leukemia (ALL) is the leading childhood cancer with a high mortality and morbidity. Studies have suggested an association of epigenetic transformations with prognosis, recurrence and immunophenotypes of ALL. SOCS1 and SOCS3 are tumor suppressors inhibiting JAK/STAT signaling pathway and the resultant aberrant cell proliferation.
Method: We aimed to assess the association between methylation status and ALL, using bone marrow and peripheral blood samples. 18 patients with ALL and 13 children with no malignancies were included. Using Bisulfite conversion, quantitative multiplex methylation-specific PCR and 2^(-∆∆Ct) formula, the methylated DNA in the promoters of SOCS1 and SOCS3 were measured.
Results: ALL patients had higher mean methylation in SOCS1 promoter and lower mean methylation in SOCS3 promoter, compared to the control group. However, neither of these mean differences were statistically significant.
Conclusion: This finding can set the foundation for further large-sample studies with the use of healthy children as a control group to strengthen the hypothetical association of the methylation status of SOCS1 and SOCS3 with ALL.

Background: Diabetes is a common disease that leads to chronic complications such as neuropathy, nephropathy, vascular diseases, and retinopathy. Diabetic retinopathy is an eye condition that can cause vision loss and blindness in diabetic patients. The aim of this study is to describe the prevalence of diabetic retinopathy in diabetic patients.
Method: In this descriptive-cross-sectional study, 550 patients with diabetes referring to the diabetes centers in Mashhad Parsian Diabetes Center, Iran were enrolled. All patients were assessed for the presence of diabetic retinopathy by direct or indirect ophthalmoscopy. A standardized protocol was used to grade diabetic retinopathy. Two groups of diabetic patients with and without retinopathy were compared in terms of body mass index (BMI), gender, disease duration and type of diabetes, history of blood pressure, history of blood lipids, hemoglobin AIC and albumin.
Results: The prevalence of diabetic retinopathy among 550 diabetic patients was 23.4% (129 patients). Age, duration of diabetic disease, history of high blood pressure, history of high blood lipids, type 2 diabetes and urine albumin were significantly different between the diabetic patients with and without retinopathy, while no significant difference was observed between the two groups in terms of gender, BMI, smoking, and hemoglobin A1C level.
Conclusion: Due to the high prevalence of DR in diabetic patients, it is recommended that retinal examination should always be considered in the evaluation of diabetic patients.

The Effectiveness of Transcranial Direct Current Stimulation (tDCS) and Omega-3 on Food Craving, Executive Functions, Weight, and Depressive Symptoms in Patients with Depression and Overweight: A Randomized Controlled Trial
Authors: Tabasi Mahla , Mostafavi Seyed-Ali , Oreyzi Hamidreza , Mohammadi Mohammad Reza , Khaleghi Ali
Published: March 2024

Objective: The most important hypothesis of this research was based on the fact that the mechanism of the effect of omega-3 on depression and obesity is formed through its accumulation in the dorsolateral prefrontal cortex (DLPFC), especially in women. Accordingly, we investigated the omega-3 intake and the concurrent stimulation of the DLPFC by tDCS and hypothesized that the synergy of these two treatments can increase the obtained effect size in patients with depression and overweight.
Method: This research was a double-blind randomized controlled trial (RCT) with a factorial design consisting of four treatment and control groups. The participants were females with depression and overweight on an outpatient basis. They received 5 ml/day omega-3 syrup (545 mg DHA, 620 mg EPA) or placebo adjunct with 12 sessions sham/tDCS stimulation administered for 3 weeks with anode-left/cathode-right protocol in the prefrontal cortex (1.5 mA, 15 minutes’ stimulation / 15-20 minutes’ rest intervals/one visit per week, 4 stimulations per visit).
Results: tDCS or omega-3 alone did not significantly improve the executive functions, depression, food cravings, and weight in the experimental groups compared to the control group (P > 0.05). However, tDCS adjunct with the omega-3 had a significant and positive effect on improving weight change (P = 0.011; df = 1; F = 1.27; Eta = 0.108) with a power of 0.73 compared to the control group. Furthermore, their interaction led to an improving trend in executive functions and a decreasing trend in food cravings which are clinically important.
Conclusion: tDCS could strengthen the omega-3 mechanisms of effect through stimulating its accumulation site in the brain (i.e., the DLPFC) and the synergistic effects of these two treatments result in weight control as well as an improvement trend in the executive functions and food craving in women.

Published: March 2024

Objective: Consequences of imprisonment include negative psychological effects, social stigma, and challenges for reintegrating into society. In this regard, this study aimed to investigate the effectiveness of Rational Emotive Behavior Therapy (REBT) on self-control and impulsivity among male prisoners.
Method: A randomized controlled clinical trial (RCT) utilizing a design the included pretest, post-test, and follow-up assessment as well as a waiting-list control group was conducted. A total of 30 male prisoners were selected using convenience sampling and randomly assigned to experimental and waiting list control groups (the intervention group (n = 15) and the control group (n = 15)). The participants in the experimental group underwent the 12-session REBT intervention over a period of six weeks. (For six weeks). All participants responded to the Self- Control Scale (SCS) and Dysfunctional Impulsivity Questionnaire (DFIQ) as dependent variables at three time points (pretest, post-test, and one-month follow-up). A repeated measures analysis of variance was used to analyze the data.
Results: The results revealed that after the implementation of the REBT intervention, the mean scores of self-control increased (P < 0.05), while the mean scores of impulsivity diminished significantly (P < 0.05). Furthermore, these changes remained relatively stable during the follow-up period (P < 0.05).
Conclusion: Based on the findings of this study, it can be inferred that REBT intervention plays a significant role in diminishing self-control deficits and mitigating impulsivity among incarcerated individuals. These results present promising implications for the utilization of REBT in lowering recidivism rates.

Published: March 2024

Objective: To understand the consequences of an invalidating environment, it is essential to have a measurement tool with appropriate statistical properties. Thus, the primary aim of this study was to render the ICES (Invalidating Childhood Environment Scale) into Persian and subsequently evaluate the psychometric attributes of this translated version.
Method: Data were collected from 1221 nonclinical participants, including 1053 females and 168 males, who were students at medical universities in Tehran, Iran. Several questionnaires, such as the ICES, CTQ (Childhood Trauma Questionnaire), DTS (Distress Tolerance Scale), BIS-11 (Barratt Impulsiveness Scale), Self-Compassion Questionnaire, Dutch Eating Behavior Questionnaire, and EAT-26 (Eating AttitudesTest) were used in the study. The data sets were investigated through SPSS and R language to evaluate the ICES' reliability and construct validity. Additionally, Item Response Theory (IRT) was employed with the Graded Response Model (GRM) to measure the psychometric properties of each item in terms of difficulty and discrimination parameters.
Results: Confirmatory factor analysis indicated that both single-factor and two-factor models fit well for both maternal and paternal versions of the ICES. The internal consistency, as assessed by Cronbach's alpha, was high and satisfactory for both maternal (0.87) and paternal (0.87) versions. Notably, the IRT analysis revealed that item 9 performed poorly in both maternal and paternal versions. Compared to the one-factor model, the two-factor model demonstrated a superior fit. Additionally, the test-retest reliability of the ICES over two months demonstrated good reliability for both maternal and paternal versions (0.98). Divergent and convergent validity analysis revealed a significant negative relationship between childhood invalidation environment and distress tolerance (r = 0.175, P < 0.01) as well as self-compassion (r = 0.142, P < 0.01), which were inversely related to the ICES. Furthermore, there was a considerably positive correlation between the invalidating environment experienced during childhood and impulsivity, as evidenced by r = 0.196 and P < 0.01.
Conclusion: This study established the favorable psychometric properties of the Persian version of the ICES, indicating that this version is reliable and valid to assess the Invalidating Childhood Environment in the Iranian population. However, further investigations are warranted to reevaluate its validity and reliability.

Published: March 2024

Objective: Early detection of autism spectrum disorder (ASD) can lead to earlier intervention and greater improvement of children’s quality of life and performance; hence, the use of screening tools is essential to facilitate the diagnosis process. The aim of the present study was to determine the clinical and differential validity of Social Responsiveness Scale-Second Edition (SRS-2) and Social Communication Questionnaire (SCQ) in a group of children and adolescents with autism spectrum disorder compared to a normal developmental group.
Method: The study was conducted in Roozbeh Hospital involving 52 children with ASD and 53 typically developing (TD) children, aged between 4-12 years. Their parents completed the SRS-2 and SCQ. These children were also interviewed using the Childhood Autism Rating Scale, 2nd Edition (CARS-2) and Asperger Syndrome Diagnostic Scale (ASDS). After completion, the results were analyzed using the SPSS Version 18 software and a significant level of 0.05.
Results: The average age of children in the autism group was 7.5 ± 2.7 years, while in the typically developing (TD) children group, it was 7.7 ± 2.3 years (P = 0.656). A positive correlation coefficient was observed between the CARS questionnaire score, the SRS questionnaire score, the SCQ questionnaire score, and the ASDS ‏(P < 0.01). In the SRS questionnaire, the area under the ROC curve was 0.976, and in the SCQ questionnaire it was 0.953, both of which had a good and significant diagnostic value (P < 0.001). A sensitivity of 0.942 and specificity of 0.811 for the cut-off point of 62.5 were obtained in the SRS questionnaire. Additionally, a sensitivity of 0.865 and specificity of 0.925 for the cut-off point of 15.5 were achieved in the SCQ questionnaire.
Conclusion: The SRS-2 and the SCQ are sensitive and specific tools for identifying and discriminating children with autism spectrum disorder.
Auditory Steady-State Evoked Potentials in Post Traumatic Stress Disorder: Introduction of a Potential Biomarker
Authors: Jahromi Gila Pirzad , Sotoudeh Hossein Gharaati , Mostafaie Romina , Khaleghi Ali
Published: March 2024

Objective: The lack of steady-state evoked potential (SSEP) studies on post-traumatic stress disorder (PTSD) has led to undiscovered useful information about the pathophysiology of the disorder. Thus, we explored SSEP patterns in PTSD patients during a stop-signal task to disclose possible impairments in these informative brain potentials.
Method: 25 adult patients with PTSD and 25 healthy adults participated in this research. Subjects were assessed with electroencephalography while the tone signal stimuli at 40 Hz were used to evoke SSEPs and subjects performed a stop-signal task. The amplitude and phase of SSEPs were then computed in different brain regions. The subjects were also evaluated using the Mississippi PTSD questionnaire. Appropriate statistical methods such as repeated measure ANOVA were used to compare the two groups, and the correlation between SSEPs and clinical symptoms was assessed using Pearson correlation analysis.
Results: Patients showed considerably poorer performance in the cognitive task (P < 0.01), accompanied by raised SSEP phase and amplitude in the anterior and midline regions compared to healthy controls (P < 0.05). The Mississippi total score was positively correlated with the SSEP amplitude in the midline region (r = 0.62, P < 0.05). Furthermore, based on ROC analysis, the SSEP amplitude in the midline region provided an excellent AUC value (AUC = 0.850) for distinguishing patients with PTSD from normal subjects.
Conclusion: Current findings suggest that abnormalities in the anterior and midline cortical neural networks are involved in the pathophysiology of PTSD. Importantly, midline abnormalities may provide a clinically-relevant measure for researchers wishing to assess the use of biomarkers for early diagnosis of PTSD as well as to evaluate new therapeutic and management approaches in the treatment of PTSD.

Published: March 2024

With the relaxation of China’s birth policies and the dual independence gained by Chinese women in both mental and economic aspects, maternity wear, as an essential item for pregnant women, has an enormous design space and a growing consumer market, attracting increasing attention from all quarters [1]. However, due to the continuous changes in pregnant womens body shapes and the fact that most women need to continue working and socializing during the early and middle stages of pregnancy [2], maternity wear has a short wearing cycle and rapid turnover [3] leading to the current unsustainable consumption of maternity wear. This study aims to explore the impact of environmental awareness on the sustainable consumption behavior of maternity wear. Specifically, the study objective is to use Grounded Theory to analyze sustainability issues within maternity wear consumption and identify the factors and stages influencing sustainable consumption behavior through online searches for relevant reports and comments. We address 2 research questions. RQ1: How to improve the sustainability of maternity wear to reduce unsustainable consumption? RQ2: How does environmental awareness influence sustainable consumption behavior in maternity wear? This article, based on Grounded Theory, to ensure the timeliness of comments and reports, conducted sample data collection from 2019 to 2022. We conducted searches using keywords such as “sustainable maternity wear,” “ecofriendly maternity wear,” “sustainable fashion,” “maternity wear consumption,” and “postpartum clothing consumption.” We obtained a total of 1086 relevant articles and materials. After careful screening, we narrowed down our searches and organized 45 feasible textual materials for our study. Through online searches for relevant reports and comments regarding sustainable consumption of maternity wear, it identified consciousness-related influencing factors and three stages of sustainable maternity wear consumption behavior. Furthermore, it proposed reference recommendations for promoting sustainable consumption of maternity wear through management practices.

Published: March 2024

This article discusses the design of a web-based portfolio and catalog integration system as a medium for learning and promoting the work of Polymedia Broadcasting Study Program students. The systems entitled ’Nakula’ and ’Sadewa’ are designed in an integrated manner to meet the needs of the distribution and promotion process of student work. There are three main needs in managing audio-visual works in the broadcasting study program: (1) The need for a work archive system. (2) Open access to works for students as a learning medium. (3) Showcase student work so that it can be accessed on a limited basis by stakeholders or sponsors. These findings can complement the findings of previous studies which have been able to use the E-portfolio system as a promotional medium and the E-Catalog as a student learning medium. These two systems are then combined into an integrated system that can answer the three main needs for the distribution and archiving of works in the broadcasting study program. The method used in this research is the development research method (DRM). This method tries to map the problem at a locus and find a solution based on the problem found. Apart from that DRM also prioritizes the involvement of each actor in these activities so that it can maximize the role of each actor. The findings in this article are a platform called Nakula-Sadewa, which has features including a showcase of student assignments that can be accessed in full version for polymedia students so that it can be maximized as a learning medium, limited access by sponsors or external parties, work archive facilities, and writing practice for students.

Published: March 2024

The high demand for plastic use today will result in environmental damage because the plastic that is widely used cannot be broken down. This plastic waste is dangerous for the sustainability of the food chain, pollutes water and soil, causes global warming, and causes air pollution. This research synthesizes a cellulose nanofiber composite with commercial starch in a 1:1 ratio with the influence of the addition of smoke liquid from palm oil waste. This research aims to process cellulose nanocomposite fibers combined with commercial starch and use them in biodegradable plastic by testing the effect of giving smoke liquid on the development of microbial substances in environmentally friendly biodegradable plastic food packaging. So the resulting product is expected to have the potential to reduce dependence on the use of synthetic plastic. This research aims to determine the optimum concentration of liquid acid from empty oil palm fruit bunches as an antimicrobial agent in the resulting bioplastic. The addition of liquid smoke changes the bioplastic properties of FTIR and XRD the attractive strength of bioplastic. The sample with the highest concentration of liquid smoke had the greatest tensile strength (2.34 MPa). The addition of liquid smoke concentration from empty oil palm shells showed a good inhibitory area for the development of bacillus cereus (10.8 mm).
