Background/Objectives: Glypican-1 (GPC1) is a heparan sulfate proteoglycan that plays a critical role in regulating various signaling pathways and tumor development. Overexpression of GPC1 promotes tumor cell proliferation and invasiveness, and is associated with poor clinical outcomes. Therefore, anti-GPC1 monoclonal antibodies (mAbs) have been developed in various modalities for tumor therapy. Methods: We developed novel anti-GPC1 mAbs using a flow cytometry-based high-throughput screening approach, the Cell-Based Immunization and Screening (CBIS) method. Results: A clone G₁Mab-28 (IgG₁, κ) reacted with GPC1-overexpressed Chinese hamster ovary-K1 (CHO/GPC1), but not parental CHO-K1, in flow cytometry. Furthermore, G₁Mab-28 recognizes the endogenous GPC1-expressing human esophageal squamous cell carcinoma KYSE770 cell line. Furthermore, G₁Mab-28 specifically recognized only CHO/GPC1, but not the other GPC family-overexpressed CHO-K1. The dissociation constant values of G₁Mab-28 for CHO/GPC1 and KYSE770 were determined to be 3.3 × 10⁻⁸ M and 4.6 × 10⁻⁹ M, respectively. Moreover, G₁Mab-28 is suitable for Western blotting and immunohistochemistry. Conclusions: G₁Mab-28, established by the CBIS method, is versatile for basic research and is expected to contribute to antibody-based tumor therapy. Full article

Introduction: Distress during pediatric magnetic resonance imaging (MRI) neuroimaging can compromise scan quality and negatively impact children’s experiences. This review aimed to systematically synthesize biomarkers and psychological factors associated with distress in children, adolescents, and young adults undergoing neuroimaging. Methods: This systematic review was conducted according to PRISMA and AMSTAR-2 guidelines and preregistered in OSF. A systematic search was performed in six electronic databases, including observational articles published between 2000 and 2025 that assessed distress during MRI and functional MRI (fMRI). Data extraction and risk of bias assessment (QUIPS tool) were performed independently by two reviewers. Results: Ten studies (n = 558) examining distress during neuroimaging were included in this review. Distress was assessed through subjective self- and parent-reports, objective physiological measures, and qualitative interviews. Overall, distress levels were low to moderate; most participants tolerated scans well, though younger age, male sex, parental anxiety, procedure length, and chronic illness were associated with greater discomfort. Noise, immobility, and boredom emerged as the most frequent triggers, while strategies such as distraction, age-appropriate information, and reducing waiting times were perceived as helpful. Among participants with cancer, scan-related anxiety was closely linked to fear of recurrence and perceived stress. Risk of bias across studies was moderate to high, particularly in domains of attrition and statistical reporting. Conclusions: Distress during scanning is driven by anticipatory and parental anxiety, procedure length, and chronic illness. Biomarkers (e.g., cortisol, blood pressure) showed inconsistent links with subjective distress, highlighting the need for integrated measures. Full article

As natural nanoscale intercellular messengers, exosomes exhibit considerable potential in modulating inflammation, angiogenesis, immunoregulation, and tissue remodeling, making them attractive candidates for regenerative medicine. However, their clinical translation remains limited by rapid systemic clearance, nonspecific biodistribution, insufficient lesion retention, and functional attenuation in hostile pathological microenvironments. In this review, we propose that biomaterial engineering should evolve from providing passive exosome carriers to constructing active regulatory platforms capable of precise spatiotemporal control. We summarize engineering strategies along two complementary dimensions. In the temporal dimension, biomaterials can enable sustained, sequential, or microenvironment-responsive release to match the dynamic phases of tissue repair. In the spatial dimension, biomaterials can improve local retention, tissue anchoring, structural guidance, endogenous cell recruitment, and lesion-specific delivery. Using cutaneous wound healing, osteochondral regeneration, myocardial repair, and neural regeneration as representative examples, we further analyze these strategies through a “clinical challenge–engineering strategy–biological mechanism” framework, with particular attention to how engineered systems influence key signaling pathways such as PI3K/Akt, Wnt/β-catenin, NF-κB, and PTEN/PI3K/Akt/mTOR. We also discuss translational barriers, including exosome heterogeneity, safety concerns inherited from parental cells, large-scale GMP-compliant manufacturing, product standardization, storage stability, and regulatory classification of exosome–biomaterial hybrids. Finally, we highlight emerging directions, including multi-mechanism combinational systems, closed-loop responsive platforms, and artificial intelligence-assisted design for personalized exosome therapeutics. This review provides a design-oriented framework to accelerate the bench-to-bedside development of biomaterial-enabled precision exosome therapy. Full article

Working from home (WFH) has increasingly been adopted globally as a family-friendly arrangement that enables employees with greater family responsibilities to reconcile work and family demands. However, little is known about which parents take up WFH in the Chinese context. Using nationally representative pre-pandemic data from the China General Social Survey 2015, this paper examines the sociodemographic determinants of parents working from home in China, with particular attention to gendered patterns among mothers and fathers. The results show no statistically significant gender difference in the overall likelihood of WFH among parents. However, the sociodemographic determinants of WFH show different patterns among mothers and fathers. Specifically, Chinese mothers are more likely to WFH when they are engaged in non-standard employment arrangements and do not live with grandparents, whereas Chinese fathers are more likely to WFH when they are employed in the agricultural sector and hold more traditional gender role attitudes. A positive but weak association is observed between the number of children and mothers’ likelihood of WFH, while no such association is found among fathers. In addition, unlike in Western contexts, WFH uptake among Chinese parents is not found to be concentrated among more advantaged groups. Full article

Tomato landraces possess distinct flavors, colors, textures and aromas, making them suitable for traditional cuisine. Tomato landraces contain a wide range of genes, including those involved in fruit quality, that can be isolated and used in local breeding programs. In regions recognized as centers of origin, domestication and diversification, traditional farmers play an important role in the preservation of tomato landraces adapted to local conditions and agricultural practices, on the whole maintaining high genetic diversity. This work aimed to evaluate the effects of the crop cycle (C), genotype (G) and C × G interactions on the contents of soluble solids, reducing sugars, lycopene, total polyphenols, flavonoids, and vitamin C, as well as the pH and antioxidant activity, in fifteen tomato landraces (genotypes) undergoing phenotypic selection and a commercial tomato variety (control). All the varieties were grown in two crop cycles under uniform greenhouse management using a randomized block design with four repetitions. Fruit composition was analyzed with AOAC and spectrophotometric methods. Significant differences (p ≤ 0.01) were detected in the soluble solid content, pH, flavor and maturity indices, polyphenol and flavonoid contents, and antioxidant activity between C, G and C × G interactions. In contrast, titratable acidity, reducing sugars, lycopene and vitamin C did not differ between cycles. Coefficients of phenotypic and genotypic variation and broad-sense heritability (H²) ranged from 4.3 to 33.7, 2.0 to 19.0, and 3.2 to 63.5%, respectively. H² for bioactive compounds ranged from moderate to slightly high (16.3–38.8%). These findings, supported by laboratory analyses, suggest that genotypes under agronomic selection have potential as parents to enhance fruit quality in current and future breeding programs.

Background/Objectives: Hyperthermia coupled with temperature-triggered drug delivery systems, including drug-loaded thermosensitive liposomes, that exhibit increased membrane permeability at hyperthermia-relevant temperatures is a promising therapeutic strategy for cancer treatment. Our previous study revealed that nitrogen-doped carbon dots (CD) partially interact with the phospholipids of liposomes, increasing the membrane permeability of an encapsulated anticancer drug. In vitro cell experiments indicated that their presence in the culture medium, albeit at relatively high concentrations, also affect cell membrane permeability, enhancing drug internalization in cancer cells. This study aims to introduce either hydrophilic or lipophilic carbon dots into liposomes and evaluate them as thermosensitive drug delivery systems. Methods: Alkylated carbon dots (CD-C16) were synthesized and liposomal systems with either the lipophilic CD-C16 or the parent hydrophilic CD were prepared and efficiently loaded with doxorubicin (DOX). Following physicochemical characterization, their thermosensitivity was studied vs. time and temperature, while their effect on cell survival at 37 and 40 °C was evaluated against HEK293 and PC3 cells. Results: At 40 °C, for CD containing liposomes 50% DOX release is observed, whereas for CD-C16 containing liposomes 95% DOX is released within 5 min. Against PC3 cells at 40 °C, both DOX-loaded CD containing liposomes and CD-C16 containing liposomes are more potent compared to the parent drug-loaded liposomes, whereas CD-C16 containing liposomes are equally potent to free DOX. Against HEK293 cells the thermosensitive formulations at 40 °C prove even more cytotoxic, with CD-C16 containing liposomes being more potent than free DOX, but CD containing liposomes are advantageous for being less toxic than free DOX at 37 °C. Conclusions: Although work is needed to elucidate the mechanism at the molecular level, the results suggest that it is possible to adjust liposomal membrane permeability through the incorporation of carbon dots in order to optimize performance for hyperthermia-based applications.

Background/Objectives: Excess consumption of energy-dense foods (EDF; ultra-processed snacks, sweets, and sugar-sweetened beverages) among preschool-aged children is a public health concern, particularly in low-income families. Caregiver parenting style, psychological stress, and food-parenting practices (FPP) may shape children’s EDF consumption, yet little is known about how these factors operate in real time. This exploratory pilot study examined (1) associations between baseline characteristics and EDF feeding episodes across 1 week and (2) whether caregivers’ momentary stress during EDF episodes related to FPP used. Methods: In total, 22 caregivers of Head Start children (ages 3–5) completed baseline measures and 7 days of ecological momentary assessment (up to seven prompts/day). At each prompt, caregivers reported child EDF consumption in the past hour; if confirmed, they reported FPP used and rated momentary stress. Aim 1 used Poisson regression to model caregiver-level EDF episode counts. Aim 2 tested momentary stress–practice associations during EDF episodes using GEE, with within-person and between-person stress modeled separately. Results: Authoritarian parenting was associated with a higher weekly rate of EDF episodes (RR = 1.43, 95% CI 1.23–1.66, p < 0.001); authoritative parenting trended lower (RR = 0.90, p = 0.065). Higher baseline stress was associated with more EDF episodes (RR = 1.25, p = 0.001). Momentarily, elevated stress above a caregiver’s own average increased odds of using food as a reward (OR = 1.08 per +10 points, p = 0.011), while higher average momentary stress was associated with co-eating (OR = 1.59, p = 0.042). Domain-level FPP composites showed no association with momentary stress. Conclusions: Authoritarian parenting and higher caregiver stress were associated with increased EDF feeding, and momentary stress was linked to reward-based feeding during those episodes. These hypothesis-generating findings suggest potential behavioral targets for just-in-time adaptive intervention, pending replication in adequately powered studies. Full article

Despite broad agreement on sensorimotor foundations of cognition, existing integrative models are not user-friendly to those who most need them—parents, caregivers, teachers, and clinical practitioners. This review addresses that gap by proposing Meaning-Events (M-Es) as sensorimotor–cognitive coordination units that structure meaning from infancy through adulthood. Drawing on joint attention research, embodied cognition, and dynamic skill theory, this integrative model demonstrates how sensorimotor processes—gaze coordination, affective timing/synchrony, bodily orientation, eye–hand coordination, and goal-directed action—organize cognitive structures of increasingly abstract meaning-making. Meaning-Events are shown as the smallest analyzable units that integrate sensorimotor experience with cognition, providing (1) developmental continuity for embodied action giving rise to coherent thought, purpose, and identity; (2) reciprocal perspectives informing impacts of dyadic behavioral interactions; and (3) an analytical and synthetic tool providing visible, measurable differentiation and integration of behaviors over time. Integration of Fischer’s dynamic skill theory with Erikson’s psychosocial theory illustrates applications in clinical and educational contexts. Rather than viewing sensorimotor experience as an early precursor superseded by symbolic cognition, the Meaning-Event model positions these sensorimotor–cognitive coordination units as constitutive of meaning at all developmental levels.

Doping remains a major threat to athlete health and sport integrity. Although anti-doping efforts have traditionally focused on athletes, increasing attention has turned to Athlete Support Personnel (ASP) due to their influence on athletes’ decisions, behaviors and involvement in anti-doping rule violations. This narrative review aimed to synthesize the existing literature on the role of ASP (including coaches, physicians, pharmacists, sport psychologists, nutritionists, physiotherapists, parents and other family members) in anti-doping, with particular attention to their influence on athletes’ knowledge, attitudes, behaviors, education and decision-making related to doping. Coaches, physicians, and pharmacists are among the ASP groups most frequently examined in the literature, although substantial knowledge gaps remain across all groups. Coaches shape motivational climates and ethical norms but often lack adequate understanding of anti-doping regulations and supplement risks. Physicians and pharmacists play key roles in medication management and Therapeutic Use Exemptions procedures, though incomplete regulatory knowledge may contribute to inadvertent violations. Nutritionists are central in preventing supplement-related doping, while research on sport psychologists and physiotherapists remains limited despite their preventive potential. Parents significantly shape athletes’ moral development and susceptibility to doping, acting as protective or risk factors depending on family dynamics. Overall, anti-doping education for ASP remains inconsistent. In conclusion, ASP plays an essential yet heterogeneous role in influencing doping-related behaviors. Strengthening role-specific and interdisciplinary anti-doping education, particularly within university programs and professional development, appears critical for enhancing ASP competence and promoting a sustainable culture of clean sport.

This study examines whether the association between parenting styles and adolescent adjustment reflects universal principles or culturally embedded processes, comparing adolescents from Germany (n = 395) and Spain (n = 331). Grounded in the bidimensional model of parental socialization (warmth × strictness), four styles were identified: authoritative, indulgent, authoritarian, and neglectful. Participants (Mage = 15.6 years) completed measures of parental socialization (ESPA29) and multidimensional self-concept (AF5); academic achievement was obtained from school records; and substance use was self-reported. A cross-sectional design was employed. Multivariate analyses of variance that revealed warmth was positively associated with all self-concept domains and negatively with substance use, whereas strictness showed weak or negative links. Significant Parenting Style × Country interactions emerged for academic self-concept, achievement, and substance use. In the Spanish sample, indulgent parenting exhibited a distinct pattern, particularly with respect to academic self-concept. Among German adolescents, both indulgent and authoritative styles yielded favorable outcomes, with authoritative parenting demonstrating protective effects against substance use. These findings suggest that the effectiveness of the authoritative style may not be uniform across contexts and underscore the importance of cultural factors in defining optimal parenting, supporting a contextualist model of adolescent socialization across European contexts.

In the Philippines’ agricultural setup, pre-harvest cacao (Theobroma cacao) fruits are wrapped with low-density polyethylene (LDPE) for moisture retention and damage protection. Responding to the growing concern for its waste volume and scarcity of treatment, this research explores the co-hydrothermal carbonization (co-HTC) of cacao shells (CS) and LDPE as a method to convert agricultural waste with plastic into hydrochar for potential energy applications. Thus, observations on the thermal, physicochemical, and morphological changes from feedstocks to hydrochar are carried out. Optimal conditions of 200 °C for 60 min resulted in hydrochar with 21.11 MJ/kg and appreciable thermal properties. SEM micrographs show that hydrochar had increased surface area, a good fuel characteristic, and surface flaking on oversized LDPE film, suggesting relative LDPE degradation. EDX analysis reveals C, K, Ca, and Zn metals that affect chemical pathways. FTIR analysis further supports chemical synergy by preservation of functional groups innate from both parent materials. Kinetic and thermal evolutions are also investigated to reveal the influence of pretreatment on the stability of cacao shell-dominated hydrochar and the effectivity of biomass integration to facilitate relatively easier cracking of LDPE. The findings support co-HTC as a viable technology to enhance the circular economy by valorizing LDPE and cacao shells while promoting energy recovery and solid fuel production. Full article

Speedcubing, the competitive practice of fast solving the Rubik’s Cube, has gained global popularity both as a sporting and an educational activity. Aside from its recreational value, speedcubing may contribute to broader social and developmental outcomes. This study aims to examine the potential of speedcubing as a tool for sustainable social development, concentrating on its educational, psychological, and social implications and its relationship to selected United Nations Sustainable Development Goals (SDGs). An anonymous online survey consisting of 26 items (22 used for the main analysis and 4 demographic items) was conducted among 112 participants associated with the speedcubing community, including active competitors, coaches, and parents. The questionnaire addressed accessibility, cognitive and social competencies, and perceived educational and social benefits, as well as user preferences regarding digital tools supporting learning. The results indicate that participation in speedcubing supports the development of analytical thinking, problem-solving skills, perseverance, and self-control. Respondents also emphasized its educational value, accessibility, and role in fostering fair play and social integration. These findings suggest that speedcubing may contribute to several Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being), SDG 4 (Quality Education), and SDG 11 and SDG 12 (Sustainable Cities and Communities; Responsible Consumption and Production).

This article examines how the discourse of “for your own good” functions as a moral framework through which parental violence is reinterpreted as care in Sinophone family cinema. Focusing on family-centered films as a key site of representation, we analyze how reconciliation is constructed not merely as a narrative resolution but as an ethical expectation. Drawing on theoretical perspectives from Michel Foucault and Louis Althusser, we develop the concept of “moralized parental violence” to describe how authority, discipline, and emotional control are legitimized through moral discourse. Through a typological analysis, identify three recurring models of reconciliation: deathbed reconciliation, retrospective understanding, and silent reconciliation. The study further explores works that resist reconciliation, arguing that such narratives suspend ethical closure and challenge normative expectations of forgiveness. By examining narrative structure, visual emphasis, and affective strategies, we demonstrate how cultural texts guide audience responses and shape moral interpretation. Rather than rejecting family values, this study reconsiders how ethics, power, and care are intertwined in cultural narratives and how the refusal of reconciliation opens a critical space for rethinking the limits of moral obligation.

The Abrolhos Magmatic Province (AMP), situated along the southeastern Brazilian passive margin, comprises a Paleocene–Eocene transitional basalt series of alkaline affinity. Despite the lack of mineral chemistry and thermobarometric estimates, it has long been linked to a classical deep-mantle plume model. This study integrates mineral chemistry, calculations of intensive parameters (P, T, H₂O), geochronology, and geochemical modeling to evaluate an alternative explanation for AMP magmatism. Whole-rock and clinopyroxene compositions from different AMP localities are consistent with parental magmas derived from fertile, pyroxenite-enriched mantle sources that melted under ambient mantle potential temperatures (~1300–1400 °C). Inverse petrological modeling using alphaMELTS and MeltPT, together with trace-element systematics, suggests low degrees of partial melting within asthenospheric domains. These results indicate that shallow (upper-mantle) processes and high mantle fertility were important controls on melt generation. New ⁴⁰Ar/³⁹Ar ages of 24.3–28.4 Ma for southern AMP rocks are also difficult to reconcile with a simple age-progressive evolution of the previously proposed plume model. Taken together, the data support ambient-temperature melting of a fertile mantle as a plausible explanation for Abrolhos magmatism and reduce the need to invoke a classical high-temperature mantle plume as the sole model. Here, we favor a tectonically controlled model, involving localized shallow mantle processes such as edge-driven convection and/or lithospheric delamination as triggers for intraplate magmatism along the South Atlantic margins.

The first female flower node (FFFN) is a crucial trait affecting earliness and yield in bitter gourd (Momordica charantia L.). To identify the genetic locus and candidate gene controlling FFFN, we performed phenotypic and genetic analyses using two parental lines, ‘M144’ (average FFFN: 6.3 ± 2.0) and ‘K55’ (average FFFN: 22.0 ± 4.5), along with their F₁ hybrid and an F₂ population consisting of 317 individuals. The results show that the low FFFN trait was incompletely dominant over the high FFFN trait. Using BSA-seq, we mapped a FFFN locus to an interval of 18.8–22.5 Mb on chromosome 4. Fine mapping with KASP markers narrowed the McFFFN4.1 to a 73.05 kb interval between markers 25QP334 and 26QP20, which contained seven predicted genes. Transcriptome analysis revealed that only Moc04g29650, which is annotated as cytochrome b-c1 complex subunit Rieske, was differentially expressed between the parents within this mapping interval. Sequence comparison identified a single SNP (C > A) in the promoter region of Moc04g29650, which was located within a putative YAB1/FIL-binding motif. Given the known role of FILAMENTOUS FLOWER (FIL) in regulating floral transition in Arabidopsis thaliana, Moc04g29650 is proposed as the most likely candidate gene for McFFFN4.1. The KASP marker 26QP20, located near Moc04g29650, showed the strongest association with FFFN in the F₂ population, with a maximum LOD score of 5.45, and thus represents a valuable tool for marker-assisted selection (MAS) breeding in bitter gourd. This study lays a foundation for cloning McFFFN4.1 and genetically improving early maturity in bitter gourd. Full article
