    Abstract Cerebral organoids, self-organizing structures with increased cellular diversity and longevity, have addressed shortcomings in mimicking human brain complexity and architecture. However, imaging intact organoids poses challenges due to size, cellular density, and light-scattering properties. Traditional one-photon microscopy faces limitations in resolution and contrast, especially for deep regions. Here, we first discuss the fundamentals of multiphoton microscopy (MPM) as a promising alternative, leveraging non-linear fluorophore excitation and longer wavelengths for improved imaging of live cerebral organoids. Then, we review recent applications of MPM in studying morphogenesis and differentiation, emphasizing its potential for overcoming limitations associated with other imaging techniques. Furthermore, our paper underscores the crucial role of cerebral organoids in providing insights into human-specific neurodevelopmental processes and neurological disorders, addressing the scarcity of human brain tissue for translational neuroscience. Ultimately, we envision using multimodal multiphoton microscopy for longitudinal imaging of intact cerebral organoids, propelling advancements in our understanding of neurodevelopment and related disorders.

    Abstract This paper presents a plugin that adds a representation of homogeneous and heterogeneous, optically thick, translucent materials on the Blender 3D modeling tool. The working principle of this plugin is based on a combination of Genetic Algorithm (GA) and Singular Value Decomposition (SVD)-based subsurface scattering method (GenSSS). The proposed plugin has been implemented using Mitsuba renderer, which is an open source rendering software. The proposed plugin has been validated on measured subsurface scattering data. It's shown that the proposed plugin visualizes homogeneous and heterogeneous subsurface scattering effects, accurately, compactly and computationally efficiently.

    Abstract Introduction: Measuring and understanding perceived occupational stress is crucial for understanding workers' experiences of stress in the workplace and its potential implications on mental health outcomes and job performance. However, there is a scarcity of brief measures containing relevant items focused solely on occupational stress, suitable for integration with risk assessment tools for work-related stress. This study aimed to validate the Perceived Occupational Stress (POS) scale in Turkish and examined its measurement invariance across Turkish and Italian samples.
    Methods: The participants included 350 Turkish teachers (55.7% male) and 160 Italian workers (60.6% female).
    Results: The results showed a single-factor structure explaining 69.61% of the total variance for the POS. The internal consistency was found to be high in both samples. The results also indicated that the factor structure of the POS was equivalent across the two groups, supporting measurement invariance.
    Conclusion: Overall, the POS demonstrated solid measurement properties, including validated factor structure, internal reliability, and measurement invariance.

    Abstract There is a scarcity of research on smoking in adolescents within a clinical (outpatient) sample, and there is no existing knowledge on the relationship between cyberbullying and smoking in this population. The primary aim of this study is to determine the prevalence of smoking among adolescents in a clinical sample. Additionally, it aims to examine the potential associations between smoking status and factors such as socioeconomic characteristics, psychiatric diagnoses, and cyberbullying levels. A cross-sectional study was performed on 200 adolescents who visited a tertiary child and adolescent psychiatry outpatient clinic. Participants were assessed using the DSM-5 based psychiatric evaluation, the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version-DSM-5 Turkish Adaptation (K-SADS-PL-DSM-5-T), the Revised Cyber Bullying Inventory-II, and the Fagerström Test for Nicotine Dependence. The study found that 21% of the sample consisted of regular smokers, with a higher prevalence observed among older adolescents. The prevalence of depression and disruptive behavior disorders was significantly greater in the smoking group compared to other groups (p:0.043,

    Abstract Background: One of the clinical responsibilities and goals of hospitals is to provide patients with comfort and security. The present study aims to assess patients' sense of security among patients in Iranian hospitals.
    Methods: The present research employed a cross-sectional design. The sample consisted of 830 patients visiting public, private, and social security hospitals in Mazandaran in the North of Iran. The required data were collected using a questionnaire developed by the researcher of this study.This questionnaire consisted of 4 dimensions:nursing, medical, advanced facilities and patient rights. The participants were selected using a proportional stratified random sampling method. Exploratory factor analysis, confirmatory factor analysis, descriptive statistics, and ANOVA were used for data analysis using SPSS version 22.
    Results: The mean scores of patients' sense of security in social security, private, and public hospitals were 4.16 ± 0.89, 3.78 ± 0.67, and 3.60 ± 0.89, respectively. Medical factors with a mean and standard deviation of 3.92 ± 0.76, advanced facilities and equipment with 3.89 ± 0.89, nursing factors with 3.87 ± 0.73, and patient rights with 3.71 ± 0.90 were the highest to the lowest scores, respectively. The results showed that the type of hospital significantly affected the mean dimensions of security (p < 0.05).
    Conclusions: The study revealed variations in the sense of securityacross the sampled hospitals. Particularly, the sense of security attributed to the patient rights factors was lower than other factors. Therefore, to enhance the sense of security for patients, it is recommended to focus on staff training and fostering a culturethat emphasizes obtaining informed consent, demonstrating respect for the patient, and introducing the medical team to the patient before initiating any treatment.

    Abstract Background: Positive childhood experiences positively influence one's adult life, while the absence of such positive experiences can potentially yield mental health problems throughout the lifespan.
    Objective: This study aimed to investigate the role of positive childhood experiences on depression and anxiety levels.
    Participants and setting: 3090 (2059 women) young adults participated in this research. They ranged in age between 18 and 68 years (M = 28.78, SD = 9.44) and completed the self-report measures including the Positive Childhood Experiences Scale, Beck Depression and Anxiety Scales and Personal Information Forms.
    Method: A cross-sectional research design was used to collect the data through social media platforms. We conducted a regression analysis to examine how positive childhood experiences contribute to depression and anxiety.
    Results: The results of correlation analysis indicated that positive childhood experiences were significantly negatively related to depression and anxiety. Regression analysis revealed that positive childhood experiences explained a significant amount of variance in the prediction of depression (10 %) and anxiety (8 %) after controlling for demographic factors.
    Conclusions: The results suggest that the frequency of positive experiences lived during childhood might significantly reduce anxiety and depression, and positive childhood experiences might positively affect them.
