Maternal contingent responsiveness moderates temperamental risk to support adaptive infant brain and socioemotional development across the first year of life.

In the first few months of life, infants display intriguing individual differences in how they react to novel stimuli in their environment. Infant "negative reactive" tendencies have been robustly linked to resting brain activity profiles that confer risk for maladaptive socioemotional outcomes. The present study examines whether and how caregiver behavior in early infancy may interact with infant negative reactivity to alter the extent to which such tendencies predict risk-related brain activity profiles. In the present study, 51 mothers (all White; age M = 32 years, SD = 3; 70.8% monthly household income > 3,400 U.S. dollars) and their infants (39.2% female at birth) participated. We measured infant negative reactivity and maternal contingent responsiveness to infant's gaze during mother-infant interactions at age 4 months. At 10-11 months, we assessed infants' resting electroencephalographic (EEG) 6-9 Hz frontal asymmetry (a marker of risk for maladaptive regulatory behaviors and withdrawal), infant fearful withdrawal, and infant empathic behavior. We found that maternal contingent responsiveness to 4-month-old infant's gaze in naturalistic interactions moderated the relation between 4-month infant negative reactivity and 11-month resting EEG asymmetry. Results suggest that maternal contingent responsiveness alters the extent to which early reactive tendencies end up "embedded" in infant brain activity profiles. Exploratory analyses revealed that the interaction between maternal contingent responsiveness and infant reactivity predicting infant resting EEG asymmetry, in turn predicted infants' fearful withdrawal and empathic behaviors also assessed at 10-11 months. Findings demonstrate the critical buffering role of maternal contingent responsive behaviors in reducing potential maladaptive neural and socioemotional outcomes.

Toll-like receptor signaling in neurons modulates C. elegans feeding behavior in a hunger state-dependent manner

Animals face the risk of encountering pathogenic microbes while foraging for resources. Assessing the risk of nutrition vs. infection can result in the behavioral regulation of immune processes. Behavioral immunity in the nematode roundworm Caenorhabditis elegans (C. elegans) is regulated, in part, by the innate immune molecule TOL-1: a homolog of vertebrate Toll-like Receptor (TLR) proteins that influences C. elegans pathogen avoidance behaviors by promoting the development of CO2-detecting chemosensory neurons. While TOL-1′s role in pathogen avoidance is well established, its role in an opposing behavior – foraging – has not been examined. In addition to pathogenic bacteria, preferred food for C. elegans, such as Escherichia coli (E. coli), create significant and aversive environmental CO2 levels which may limit feeding behaviors in a tol-1 dependent manner. We have found that in addition to conferring antibacterial immunity, TOL-1 signals in neurons through the p38 MAPK PMK-1 to promote turning behavior and limit foraging when food is abundant and that the anorectic TOL-1/PMK-1 pathway is attenuated during starvation to promote foraging These data highlight the dynamic role of a conserved innate immune cascade in neurons during both high and low hunger states and identify mechanisms underlying the neuro-immune control of feeding strategies.

Cell migration behavior regulation by nanopillars and oxide coating

Cell migration behavior regulation by nanopillars and oxide coating

Paternal behaviour is associated with high levels of OT in plasma and the presence OTR in the mPOA/BNST in the Mongolian gerbil (Meriones unguiculatus)

The exhibition of paternal behaviour has been associated with high peripheral concentrations of oxytocin (OT) and levels of oxytocin receptors (OTRs) in the paraventricular and supraoptic nuclei of the hypothalamus. The presence of OTRs in the medial preoptic area (mPOA), bed nucleus of the stria terminalis (BNST), medial amygdala (MeA), and olfactory bulb (OB) has not been studied extensively in the paternal context, although these nuclei are essential in the regulation of paternal behaviour. The aim of this study was to determine whether there is an association between paternal response of sexually inexperienced males of the Mongolian gerbils (Meriones unguiculatus) and OT concentrations in plasma, as well as the presence of OTRs in the mPOA, BNST, MeA, and OB. We used sexually inexperienced gerbils: ten paternal (PAT) males and 10 males aggressive with pups (AGG). PAT males and AGG males were subjected to paternal behaviour tests. Then, blood samples were taken to quantify OT concentrations. The brains were dissected for OTR immunohistochemistry analyses. PAT males had significantly higher plasma levels of OT and numbers of cells with OTR immunoreactivity (ir) in the mPOA/BNST. These results indicated an association between paternal behaviour and peripheral concentrations of OT, as well as the presence of OTRs in the mPOA and BNST. This suggests that OT and OTRs could participate in the regulation of paternal behaviour in the Mongolian gerbil.

Exercise as a Therapeutic Strategy for Obesity: Central and Peripheral Mechanisms

Obesity is a complex, multifactorial condition involving excessive fat accumulation due to an imbalance between energy intake and expenditure, with its global prevalence steadily rising. This condition significantly increases the risk of chronic diseases, including sarcopenia, type 2 diabetes, and cardiovascular diseases, highlighting the need for effective interventions. Exercise has emerged as a potent non-pharmacological approach to combat obesity, targeting both central and peripheral mechanisms that regulate metabolism, energy expenditure, and neurological functions. In the central nervous system, exercise influences appetite, mood, and cognitive functions by modulating the reward system and regulating appetite-controlling hormones to manage energy intake. Concurrently, exercise promotes thermogenesis in adipose tissue and regulates endocrine path-ways and key metabolic organs, such as skeletal muscle and the liver, to enhance fat oxidation and support energy balance. Despite advances in understanding exercise’s role in obesity, the precise interaction between the neurobiological and peripheral metabolic pathways remains underexplored, particularly in public health strategies. A better understanding of these interactions could inform more comprehensive obesity management approaches by addressing both central nervous system influences on behavior and peripheral metabolic regulation. This review synthesizes recent insights into these roles, highlighting potential therapeutic strategies targeting both systems for more effective obesity interventions.

A four-factor model of executive function: Predicting physical and academic outcomes from cognitive assessments in adolescents

Impulsivity and cognitive function are essential for understanding behavioral regulation, particularly in relation to health-risk behaviors like substance use, physical activity, and academic performance. This study examined the factor structure underlying executive function in adolescents using the UPPS-P Impulsive Behavior Scale and NIH Toolbox Cognition Battery. We explored how parental monitoring moderates, and peer network health and perceived stress mediate, relationships between cognitive function and outcomes such as BMI, physical activity, and academic performance. Exploratory factor analysis (EFA) on 2228 observations identified a four-factor model (BIC = −97.92, RMSEA = 0.040, TLI = 0.936), validated by confirmatory factor analysis (CFA) (CFI = 0.961, RMSEA = 0.055). Structural equation modeling (SEM) on 5902 observations showed that parental monitoring moderated Factor 1 (adaptive impulsivity) in relation to physical activity and academic performance, while peer network health mediated Factor 2 (emotional impulsivity) effects on BMI and physical activity. This model underscores the influence of peer relationships, parental involvement, and stress on cognitive, health, and academic outcomes, suggesting that interventions enhancing peer support, reducing stress, and promoting healthy behaviors may improve adolescent well-being.

A profile approach to physical activity levels: what’s intensity got to do with reasons and motives for exercise?

BackgroundDespite the well-known benefits of physical activity (PA), non-communicable disease and premature mortality rates among adults continue to rise. The relationship between adults’ goals and exercise-specific motivation on the type of PA intensity one engages remains unclear. The purpose of this study was to identify physical activity (PA) profiles based on frequency and intensity (i.e., levels of PA) in an adult sample. A secondary purpose was to examine how the PA profiles differ on the reasons people have for exercising and behavioral regulation.MethodsA Cross-sectional survey was conducted with 1,169 (46.8 ± 16.7 years) participants solicited from a hospital-affiliated wellness center, social media promotions, and a research volunteer registry. The International PA Questionnaire (IPAQ) was used to determine frequency, intensity, and time spent engaging in PA. Additionally, the Reasons to Exercise (REX-2) scale, the Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3), and demographics were assessed. K-cluster analyses were performed to identify profiles based on PA levels using the IPAQ guidelines. Multivariate analysis of variance (MANOVA) was used to assess profile differences.ResultsFive distinct PA clusters were derived, and defined as: a Low, Walking, Moderate Intensity, High Intensity, and Sitting cluster (p < .001). These clusters differed significantly (p < .001) from each other with respect to motivation, the reasons adults have for exercise, and PA levels.ConclusionThe results from this study support the important role of psychological factors such as motivation and reasons for exercise on behavioral outcomes (i.e., physical activity). For future research investigating adults PA- related behaviors, whether it be on adults starting a new exercise program or for PA maintenance, it may be beneficial to develop programs that encourage participants to reflect on the reasons they identify as important for exercising, and how such reasons contribute to their overall PA engagement behaviors.

Cell-microsphere based Living Microhybrids for Osteogenesis Regulating to Boosting Biomineralization

Abstract Biomineralization-based cell-material living composites ex vivo showed great potential for living materials construction and cell regulation. However, cells in scaffolds with unconnected pores usually induce confined nutrient transfer and cell-cell communications, affecting the transformation of osteoblasts into osteocytes and the mineralization process. Herein, the osteoblast-materials living hybrids were constructed with porous PLLA microspheres using a rational design, in which cell-based living materials presented an improved osteoblast differentiation and mineralization model using rationally designed cell-microsphere composites. The results indicated that the microfluidic-based technique provided an efficient and highly controllable approach for producing on-demand PLLA microspheres with tiny pores (&amp;lt; 5 μm), medium pores (5-15 μm), and large pores (&amp;gt; 15 μm), as well as further drug delivery. Furthermore, the simvastatin (SIM)-loaded porous PLLA microsphere with ε-polylysine (ε-PL) modification was used for osteoblast (MC3T3-E1) implantation, achieving the cell-material living microhybrids, and the results demonstrated the ε-PL surface modification and simvastatin could improve osteoblast behavior regulation, including cell adhesion, proliferation, as well as the antibacterial effects. Both in vitro and in vivo results significantly demonstrated further cell proliferation, differentiation, and cascade mineralization regulation. Then, the qPCR or histological staining of typical markers, including collagen type I (Col I), alkaline phosphatase (ALP), runt-related transcription factor 2 (Runx2) and bone morphogenetic protein 2 (BMP2), as well as the calcium mineral deposition staining in situ, reconfirmed the transformation of osteoblasts into osteocytes. These achievements revealed a promising boost in osteogenesis towards mineralization at the microtissue level by cell-microsphere integration, suggesting an alternative strategy for materials-based ex vivo tissue construction and cell regulation, further demonstrating excellent application prospects in the field of biomineralization-based tissue regeneration.

Autonomic response and attachment style in disruptive mood dysregulation disorder.

Disruptive mood dysregulation disorder (DMDD) is characterised by severe emotion regulation difficulties, particularly anger and irritability, in children. Despite the impact of attachment on emotional and behavioural regulation, the link between attachment style and DMDD is under-researched. This study investigated whether attachment style and parasympathetic regulation differentiate the response profiles to frustrating conditions between children diagnosed with DMDD and controls. Participants were assessed at schools in Johannesburg, Gauteng, South Africa. Thirty participants were divided into two matched groups (n DMDD = 15; n Control = 15) and assessed. Respiratory sinus arrhythmia (RSA) and heart period were measured during an Affective Posner Task, inducing frustration. Attachment style was assessed using the Attachment Style Classification Questionnaire for children. Parents of children with DMDD completed a social interaction problems questionnaire. The DMDD group showed a higher prevalence of avoidant attachment style (p = 0.013) compared to controls. Both groups displayed adaptive vagal withdrawal and recovery during the task (p = 0.005; p = 0.021). Controls had significantly higher heart period throughout the assessment (game 1: p = 0.006; game 2: p = 0.013; game 3: p = 0.007). In the DMDD group, lower vagal tone during frustration correlated with more social interaction problems (p = 0.049). The study demonstrates a potential link between attachment style and altered physiological state in children with DMDD. The findings provide insight into possible atypical vagal regulation of the heart and avoidant attachment styles in DMDD, highlighting potential therapeutic and intervention targets.

Hearts and minds: a community-based systems diagram exploring mental health following a cardiac event

Abstract Background/Introduction Following an acute cardiac event, individuals commonly face multiple emotional and mental health challenges. For many people, this change in their mental health will resolve over time. However, one in five will go on to develop major depressive disorder. The development of major depressive disorder is a complex co-morbidity that, if left unchecked, can increase the risk of subsequent cardiac events and mortality. Systems thinking methodology offers a novel approach to investigating factors that contribute to mental health following a cardiovascular event. Purpose This project aims to (1) unravel the complex system influencing mental health after a cardiac event and (2) pinpoint priorities for supporting individuals' mental well-being following a cardiac event. Methods Group model building workshops using Deakin University’s purpose-built STICKE software were conducted over Zoom to explore the interrelationships contributing to mental health following a cardiovascular event. Twelve participants, including consumers (n = 3) and healthcare professionals (n = 9) from across Australia, engaged in two 1.5-hour workshops. Guided by the prompt "Reflect on factors influencing a person’s mental health post-cardiac event", participants worked together to construct a systems diagram. This facilitated exploration, visual mapping, and identification of factors and priority areas influencing mental health post-cardiac event. The diagram was then analysed using the theoretical domains framework. Results The STICKE diagram developed demonstrates the interplay of various factors impacting mental health across the cardiac healthcare journey at both patient and system levels (see Figure 1). Using the theoretical domains framework, eight domains were identified: knowledge, skills of healthcare professionals, environmental context, personal context, emotional response to event and recovery, social influences, behavioural regulation, and beliefs about individual capacity. Knowledge (including health literacy and staff training), environmental context (addressing gaps in care and navigating the system), and social influences (such as social isolation) were domains that were consistently raised in the workshop (see Figure 2). Stakeholders also identified the following key priority areas: highlighting the need for additional support for staff and intervention to increase health literacy and knowledge around mental health. Conclusion(s) Supporting mental health post-cardiac events is a multifaceted challenge requiring a comprehensive community-level intervention, particularly in the initial weeks post-hospitalisation. The insights gained from this study will inform the co-design of an intervention aimed at increasing health literacy and knowledge around mental health following a cardiovascular event.

Association between infant feeding behavior and maternal choice of breastfeeding type

Abstract Introduction Feeding in infants is a fundamental process influenced by the mother-child relationship during the early months of life. The regulation of feeding behavior, and hunger and satiety cues may be interpreted by the mother, potentially relating to the type of feeding chosen. Objectives To determine the association between infant feeding behavior and the type of breastfeeding chosen by the mother. Methods A cross-sectional and prospective study was conducted, including mothers with children aged between 6 and 18 months. Those with medical contraindications for immediate postpartum breastfeeding or with suspension of exclusive breastfeeding during the first 6 months of life due to medical prescription were excluded. The Baby Eating Behavior Questionnaire was used to evaluate the baby’s enjoyment of food, appetite response, eating speed, and satiety response. Results 108 mothers were included, with 87% in agreement with exclusive breastfeeding (EBF), 43.3% using breastfeeding as the primary feeding method, and only 33.3% practicing EBF during the first 6 months. Food response (FR) scored 19.6 (±4.3), enjoyment of food (EF) 17.6 (±2.1), satiety response (SR) 7.1 (±2.0), eating speed (ES) 8.8 (±2.3), and appetite (AP) 4.2 (±0.7). Comparing FR, EF, SR, ES, and AP scores between those who practiced EBF and those who did not showed p &amp;gt; 0.05. sociodemographic characteristics, perinatal factors, stance on EBF, number of hours per day with the child, feeding location, poor technique, breastfeeding pain and lack of medical guidance, all showed p &amp;gt; 0.05 when comparing between those who practiced EBF and those who did not; in contrast to perceiving that the baby wanted to breastfeed (2.5/1.0-6.2), having time to feed (3/1.2-7.2) and having no health problems (10/1.2-78.7) all with p-value &amp;lt;0.05. Conclusions The mother’s perception identifying the baby’s desire to breastfeed, having time to feed the baby and not having health problems favor exclusive breastfeeding. Key messages • Maternal perception plays an important role in deciding to give SCI, so it is the physician’s job to educate the mother so that she has additional arguments for choosing SCI. • The infant’s feeding behavior does not have a significant impact on the mother’s behavior in choosing SCI feeding.

Cholecystokinin-expressing neurons of the ventromedial hypothalamic nucleus control energy homeostasis.

The hypothalamus is the primary center of the brain that regulates energy homeostasis. The ventromedial hypothalamus (VMH) plays a central role in maintaining energy balance by regulating food intake, energy expenditure, and glucose levels. However, the cellular and molecular mechanisms underlying its functions are still poorly understood. Cholecystokinin (CCK) is one of many genes expressed in this hypothalamic nucleus. Peripheral CCK regulates food intake, body weight, and glucose homeostasis. However, current research does not explain the function of CCK neurons in specific nuclei of the hypothalamus and their likely roles in network dynamics related to energy balance and food intake. This study uses genetic and pharmacological methods to examine the role of CCK-expressing neurons in the VMH (CCKVMH). Namely, using a previously generated BAC transgenic line expressing Cre recombinase under the CCK promoter, we performed targeted manipulations of CCKVMH neurons. Histological and transcriptomic database analysis revealed extensive distribution of these neurons in the VMH, with significant heterogeneity in gene expression related to energy balance, including co-expression with PACAP and somatostatin. Pharmacogenetic acute inhibition via Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) resulted in increased food intake and altered meal patterns, characterized by higher meal frequency and shorter intermeal intervals. Furthermore, diphtheria toxin-mediated ablation of CCKVMH neurons led to significant weight gain and hyperphagia over time, increasing meal size and duration. These mice also exhibited impaired glucose tolerance, indicative of disrupted glucose homeostasis. Our findings underscore the integral role of CCKVMH neurons in modulating feeding behavior, energy homeostasis, and glucose regulation. This study enhances our understanding of the neurohormonal mechanisms underlying obesity and metabolic disorders, providing potential targets for therapeutic interventions.

Stretched Vascular Endothelial Cells Polarized Neutrophils to N2 Type via TRPC1-IL13-STAT3 Axis.

VECs play a crucial role in regulating the function of neutrophils, which is essential for immune responses and inflammation. As stretch-sensitive cells, VECs sense mechanical stretch through surface mechanoreceptors, converting external mechanical stimuli into biochemical signals. This study aimed to explore the molecular mechanisms underlying the regulation of neutrophil behavior by stretched VECs. The key cytokine-inducing neutrophil N2 polarization in the conditioned medium from stretched vascular endothelial cells (CM-stretch) was validated through multifactorial matrix and flow cytometry. Additionally, the molecular mechanism underlying the response of vascular endothelial cells to stretch was systematically verified through layer-by-layer analysis using WB. IL13, not IL4, was ultimately identified as a key cytokine-inducing neutrophil N2 polarization in CM-stretch. Inhibition of the transient receptor potential channel (TRPC1) and siRNA-mediated knockdown of TRPC1 both significantly decreased IL13 production. Furthermore, neutralizing IL13 in the CM-stretch or inhibiting STAT3 phosphorylation inhibited neutrophil N2 polarization, as evidenced by reduced CD206 and VEGFA expression. These results demonstrate that stretched VECs initiate a signaling cascade that induces neutrophil N2 polarization through the TRPC1-IL13-STAT3 axis, suggesting that mechanical stretching of VECs could shift neutrophil function from a pro-inflammatory to a more regulatory and healing role.

Family therapy and EMDR after child abuse and neglect: moderating effects of child attachment style and PTSD symptoms on treatment outcome

ABSTRACT Background: Effective and appropriate care and treatment for children in order to decrease the psychosocial problems that arose after experiencing child abuse and neglect (CAN) is of vital importance, given the severity of symptomatology that may develop. Objective: The purpose of the present study was to examine whether attachment style and core cluster Posttraumatic Stress Disorder symptoms acted as moderators for treatment outcomes of a new integrative treatment model for trauma and attachment. In this treatment model, family therapy is combined with EMDR and obstacles for trauma processing are tackled first. Method: we included children, ages 6–12 years, with a history of CAN, who did not respond to evidence-based trauma treatment. Target treatment outcomes were problems in attachment, posttraumatic stress symptoms, behaviour, and emotion regulation. We conducted a multiple-baseline ABC Single-Case Experimental Design (SCED). We categorized 12 participants into four groups of attachment style and core cluster PTSD symptoms: (1) non-disorganized & re-experiencing; (2) non-disorganized & avoidance/hyperarousal; (3) disorganized & re-experiencing; & (4) disorganized & avoidance/hyperarousal. We compared the four groups with each other and across time, and the interaction between groups and effect over time. We conducted non-parametric permutation tests and estimated q-values for false discovery rate control. Results: Children with a disorganized attachment style had more severe symptomatology in general, except for posttraumatic stress symptoms. The treatment appeared more effective in targeting and successfully treating children with a non-disorganized attachment style, and specifically children with a non-disorganized attachment style and re-experiencing as core cluster PTSD symptoms. Conclusion: Our study underlines the complexity of treating children who developed a complicated combination of symptomatology after CAN and calls for the continuous development of innovative interventions.

Heterostructure of Hydrogen‐Bonded Organic Frameworks for White Light Emission and Information Encryption

AbstractTwo dumbbell‐shaped building blocks (TMB and TMBT), featuring methyl benzoate groups as hydrogen bond units, are selected to construct heterostructures of HOFs, aiming to achieve multiple functions including white luminescence, stimulus‐response behavior, as well as application in information encryption. TMB molecules are self‐assembled to form a flexible HOF (X‐HOF‐8) in p‐xylene, containing solvent channels and blue fluorescence. Upon removal of guests, it can transform into a nonporous crystal with gray fluorescence. In contrast, TMBT forms a guest‐free HOF (X‐HOF‐9) displaying orange fluorescence. They could form bulk heterojunction (BHJ) HOFs with energy transfer from TMB to TMBT, exhibiting composition‐dependent fluorescent color. Notably, white emission can be achieved in BHJ HOFs and can be converted to gray fluorescence upon guest removal; subsequently, white fluorescence is restored upon re‐capturing guests. Furthermore, rod‐like triblock heterojunction (THJ) HOFs can also be constructed, which exhibit regulatory behavior in response to gaining or losing guests. The unique luminescent characteristics and stimulus responsiveness of these HOFs make them an excellent platform for applications in anticounterfeit. This represents the pioneering achievement of white light emission in a BHJ HOF, as well as the groundbreaking realization of a THJ HOF with remarkable exciting response characteristics.

Controllable Regulation of CO2 Adsorption Behavior via Precise Charge Donation Modulation for Highly Selective CO2 Electroreduction to Formic Acid.

The synthesis of value-added products via CO2 electroreduction (CO2ER) is of great significance, but the development of efficient and versatile strategies for the controllable selectivity tuning is extremely challenging. Herein, the tuning of CO2ER selectivity through the modulation of CO2 adsorption behavior is proposed. Using the constructed zeolitic MOF (SNNU-339), CO2 adsorption behavior is controllably changed from *CO2 to CO2* via the precise ligand-to-metal charge donation (LTMCD) regulation. It is confirmed that the high electronegativity of the coordinate ligand directly restricts the LTMCD, reduces the charge density on the metal sites, lowers the Gibbs free energy for CO2* adsorption, and leads to the transformation of CO2 adsorption mode from *CO2 to CO2*. Owing to the modulated CO2 adsorption behavior and regulated kinetics, SNNU-339 exhibits superior HCOOH selectivity (≈330% promotion, 85.6% Faradaic efficiency) and high CO2ER activity. The wide applicability of the proposed approach sheds light on the efficient CO2ER. This study provides a competitive strategy for rational catalyst design and underscores the significance of adsorption behavior tuning in electrocatalysis.

Effectiveness of functional communication training in the regulation of self-injurious behavior in children and adolescents diagnosed with autism spectrum disorder: an empty systematic review

Background: Self-injurious behaviors are highly prevalent in individuals with autism spectrum disorder (ASD), occurring frequently in those with associated intellectual disabilities as well as in those without intellectual impairment. Single-case studies have found that functional communication training helps regulate self-injurious behaviors and repetitive behaviors, particularly in children with ASD. However, no review identifies whether there is experimental evidence to support the use of this treatment. Objective: Our review aims to determine the efficacy of functional communication training for regulating self-injurious behavior in children and adolescents diagnosed with ASD. Methods: A systematic review was conducted.PubMed, Scopus, Web of Science, and Embase were searched for single-case experimental studies and randomized clinical trials. Results: A total of 67 studies were initially identified, of which 16 remained eligible after duplicate elimination and selection based on title and abstract. However, a thorough review of each text revealed that some needed to meet the inclusion criteria or had exclusionary elements. Therefore, they did not qualify for the next stage of the process. As a result, no publications were found that provided robust evidence to support the efficacy of functional communication training in regulating self-injurious behaviors in children and adolescents diagnosed with ASD. However, four publications met the secondary objective of identifying relationships between the proposed variables and presenting variations of the proposed intervention prototype. The quality of these publications was assessed and discussed according to the transparency recommendations of the Cochrane Effective Practice and Organization of Care guideline for reporting reviews without eligible or empty studies and the PRISMA 2020 guidelines. Conclusions: There is an urgent need for more research in this area, given the harmfulness and self-injurious behaviors, in addition to their high incidence in individuals diagnosed with ASD. This study's results help identify existing knowledge gaps and suggest new directions for research in this area.

CXC chemokine receptor 4 - mediated immune modulation and tumor microenvironment heterogeneity in gastric cancer: Utilizing multi-omics approaches to identify potential therapeutic targets.

G-protein-coupled receptors (GPRs) are critical regulators of various biological behaviors, and their role in gastric cancer (GC) progression is gaining increasing attention. Among them, the immune regulatory mechanisms mediated by chemokine receptor 4 (CXCR4) remain insufficiently understood. This study aims to explore the immune regulatory functions of CXCR4 and the heterogeneity of the tumor microenvironment (TME) by examining GPR-related gene expression in GC. Through multi-omics approaches, including spatial transcriptomics and single-cell RNA sequencing, we investigated the oncogenic mechanisms of CXCR4, particularly its role in T cell immune exhaustion. In vitro experiments, including ELISA, PCR, CCK8 assays, cell scratch assays, and colony formation assays, were used to validate the role of CXCR4 in the migration and invasion of AGS and SNU-1 cell lines. CXCR4 silencing using siRNA further demonstrated its regulatory effects on these cellular processes. Our results revealed a strong correlation between elevated CXCR4 expression and increased exhaustion of regulatory T cells (Tregs) in the TME. Furthermore, heightened CXCR4 expression was linked to increased TME heterogeneity, driven by oxidative stress and activation of the NF-κB pathway, promoting immune evasion and tumor progression. Silencing CXCR4 significantly inhibited the invasive and proliferative abilities of AGS and SNU-1 cells, while also reducing the expression of pro-inflammatory cytokines IL-1β and interleukin-6, thus alleviating chronic inflammation and improving TME conditions. In conclusion, our comprehensive investigation highlights CXCR4 as a key mediator of TME dynamics and immune modulation in GC. Targeting CXCR4 presents a promising therapeutic strategy to slow tumor progression by reducing Tregs-mediated immune exhaustion and TME heterogeneity, positioning it as a novel therapeutic target in GC treatment.

Standardizing a Questionnaire of Metacognitive Resources of Human Behavior Regulation in Difficult Circumstances

Modern psychology focuses on personal resources that help to overcome difficult circumstances accompanied by anxiety and stress. However, psychological diagnosis in this sphere remains understudied. The present research was an attempt to standardize a questionnaire of metacognitive regulation of human behavior in difficult circumstances. The study involved 559 participants from Tomsk (24.8% men, average age – 22.1). The exploratory factor analysis identified four factors (45.6% variance): self-control of behavior (six items, Cronbach’s alpha, α = 0.780; composite reliability = 0.863); anxiety control (four items, α = 0.823; composite reliability = 0.866); memory efficiency (three items, α = 0.817; composite reliability = 0.832); intuitive cognition of people (four items, α = 0.709; composite reliability = 0.757). Confirmation factor analysis showed high values of the model fitness indices: RMSEA = 0.044; SRMR = 0.059; CFI = 0.991; GFI = 0.986. The scales of the new questionnaire demonstrated the required external convergent validity and were found consistent with similar constructs. The study involved the following methods: D. V. Lyusin’s Emotional Intelligence Questionnaire; Subjective Risk Intelligence Scale developed by G. Craparo et al. and adapted by T. V. Kornilova and E. M. Pavlova, E. Yu. Mandrikova’s Activity Self-Organization Questionnaire, C. D. Spielberger’s Anxiety Test adapted by V. N. Karandashev, C. D. Spielberger’s Questionnaire of Personal Anxiety adapted by Yu. L. Khanin, and the Academic Motivation Scale developed by T. O. Gordeeva, O. A. Sychev, and E. N. Osin. The following scales demonstrated a good discriminative ability associated with statistically significant gender differences: self-control of behavior (p = 0.002); anxiety control (p &lt; 0.001), and memory efficiency (p &lt; 0.001). The questionnaire proved to be an efficient tool of studying human resources related to overcoming difficult circumstances.

Wideband ratiometric measurement of tonic and phasic dopamine release in the striatum.

Reward learning, cognition, and motivation are supported by changes in neurotransmitter levels across multiple timescales. Current measurement technologies for various neuromodulators (such as dopamine and serotonin) do not bridge timescales of fluctuations, limiting the ability to define the behavioral significance, regulation, and relationship between fast (phasic) and slow (tonic) dynamics. To help resolve longstanding debates about the behavioral significance of dopamine across timescales, we developed a novel quantification strategy, augmenting extensively used carbon-fiber Fast Scan Cyclic Voltammetry (FSCV). We iteratively engineered the FSCV scan sequence to rapidly modify electrode sensitivity within a sampling window and applied ratiometric analysis for wideband dopamine measurement. This allowed us to selectively eliminate artifacts unrelated to electrochemical detection (i.e., baseline drift), overcoming previous limitations that precluded wideband dopamine detection from milliseconds to hours. We extensively characterize this approach in vitro, validate performance in vivo with simultaneous microdialysis, and deploy this technique to measure wideband dopamine changes across striatal regions under pharmacological, optogenetic, and behavioral manipulations. We demonstrate that our approach can extend to additional analytes, including serotonin and pH, providing a robust platform to assess the contributions of multi-timescale neuromodulator fluctuations to cognition, learning, and motivation.
