Textile-to-textile recycling is strongly constrained by upstream pre-processing, where post-consumer clothing must be identified, separated, and prepared under high variability in materials, appearance, and contamination. This paper presents a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-guided systematic literature review of intelligent and automated technologies for textile recycling pre-processing covering the interval between 2015 to 2025. After screening and quality assessment, 21 primary studies published between 2020 and 2025 were included. The literature is synthesized across three task families: (i) identificationof fiber/material, composition, or color; (ii) sorting, considered only when explicit separation strategies are defined to operationalize identification outcomes into routing actions or output streams; and (iii) contaminant detection and/or removal, targeting non-recyclable items. Results show that identification dominates the field (19/21 studies), supported by Red–Green–Blue (RGB) and red–green–blue plus depth (RGB-D) imaging and material-signature sensing, including near-infrared (NIR) spectroscopy, hyperspectral imaging (HSI), and Raman spectroscopy. In contrast, sorting as a defined separation stage is less frequent (4/21), and contaminant-related automation remains sparse (3/21). Most studies are validated in laboratory conditions, with limited semi-industrial evidence, highlighting a persistent perception-to-action gap. Overall, the review indicates that robust separation strategies, representative datasets, and end-to-end system integration remain key bottlenecks for scalable automated textile recycling pre-processing.

Background: Adolescence is a sensitive developmental period marked by heightened emotional reactivity and increasing demands on emotion recognition and regulation. Although alexithymia has been associated with less adaptive and avoidant coping tendencies in adolescents, most prior research has relied on descriptive or bivariate approaches, leaving the underlying processes and model-based pathways insufficiently clarified. In particular, the explanatory role of difficulties in emotion regulation in the association between alexithymia and coping strategies remains underexplored. This study aimed to address this gap by examining whether difficulties in emotion regulation mediate the relationship between alexithymia and coping strategies in adolescents. Methods: In this cross-sectional study, 1415 adolescents (13–17 years) from public high schools in Central Anatolia, Türkiye, completed the Toronto Alexithymia Scale (TAS-20), the Difficulties in Emotion Regulation Scale (DERS-16), and the Coping Strategies Indicator (CSI). Pearson correlations were calculated. Mediation analyses were conducted using PROCESS Macro (Model 4) with 5000 bootstrap samples, adjusting for age, gender, academic achievement, and family type. Results: Alexithymia was moderately associated with emotion regulation difficulties (r = 0.49, p < 0.001). Mediation analyses revealed significant indirect effects for seeking social support (B = −0.068, 95% CI [−0.087, −0.051]) and problem solving (B = −0.067, 95% CI [−0.086, −0.049]), with direct effects remaining significant, indicating inconsistent (competitive) mediation patterns. For avoidance coping, the indirect effect was significant (B = −0.072, 95% CI [−0.090, −0.055]), whereas the direct effect became non-significant, consistent with an indirect-only mediation pattern. Correlations involving coping outcomes were small in magnitude. According to Cohen’s criteria, the association between alexithymia and emotion regulation difficulties was moderate in magnitude, whereas correlations involving coping outcomes were small. Conclusions: Difficulties in emotion regulation emerged as a statistical mediator within the proposed model, demonstrating systematic associations between alexithymia and distinct coping patterns in adolescents. These findings underscore the relevance of emotion regulation–focused prevention and intervention efforts in school settings. By examining multiple coping outcomes simultaneously within a covariate-adjusted mediation framework in a large community adolescent sample, this study offers an integrative, model-based perspective on how alexithymic traits are linked to coping through regulatory difficulties.

Sonchus oleraceus L., a member of the Asteraceae family native to Eurasia, is a herbaceous plant whose young stems and leaves are consumed globally as a medicinal and edible wild vegetable; it is rich in flavonoids and exhibits various pharmacological activities, including anti-inflammatory and anti-tumor effects. This study optimized the extraction process of flavonoids from Xinjiang S. oleraceus using response surface methodology and evaluated the anti-inflammatory activity of luteoloside in vitro. Based on single-factor experiments and Box–Behnken design, the effects of ethanol concentration, extraction time, solid-to-liquid ratio, and extraction temperature on flavonoid yield were investigated. The optimal extraction conditions were determined as ethanol concentration 62%, extraction time 30 min, solid-to-liquid ratio 1:91 g/mL, and extraction temperature 64 °C, with a flavonoid yield of 21.64 mg/g. After purification via polyamide column chromatography, the luteoloside content was determined by HPLC to be 44.06 μg/g. Cytotoxicity assays revealed that a luteoloside concentration of 100 μmol/L reduced the viability of Oryctolagus cuniculus colon epithelial cells to approximately 80%. ELISA results demonstrated that luteoloside significantly inhibited the release of pro-inflammatory factors, including TNF-α, while promoting the expression of the anti-inflammatory factor IL-10. These findings indicate that luteoloside effectively alleviates LPS-induced cellular inflammation. Full article

Background/Objectives: The mediating role of the diverse range of screen-based sedentary behaviors (SBs) remains understudied, particularly at younger ages. The present study examined the direct and indirect effects of parental BMI and education on ultra-processed food (UPF) consumption among preschoolers, testing the potential mediating role of screen time. Methods: The cross-sectional study sample comprised 919 kindergarten children (484 boys, 52.7%), with ages ranging from 2.2 to 6.8 years (mean: 4.7 ± 1.0 years). Screen-based sedentary behaviors (television viewing, smartphone use, tablet use, computer use, and playing electronic games) were measured by proxy-report fulfilled by parents, separately for weekdays and weekends. UPF consumption (drinks/yogurts, packaged/fast foods, and sweet/salty snacks) was assessed via 24 h recall scales. Path analysis mediation models tested direct effects of maternal/paternal BMI and education on UPF intake, and indirect effects through screen time, controlling for child age and sex. Results: Lower parental education and higher parental BMI were associated with increased mobile device use and UPF consumption (r = 0.10–0.28). Screen-based sedentary behaviors mediated the association between maternal BMI and UPF pathways (15–90% of total effects), particularly for sweet and salty snacks (50–90%). Parental education effects were also mediated by screen time (9–23% indirect effects), with paternal education showing stronger protection against packaged/fast foods. Conclusions: Mobile devices and watching television partially mediate intergenerational transmission of obesogenic dietary patterns from parental BMI/education to preschoolers’ UPF consumption. Findings of the current study support family-centered interventions targeting screen-time limits and UPF exposure, mainly at the weekends, to prevent early obesity trajectories. Full article

Background and Clinical Significance: Mucopolysaccharidosis type VI is a rare lysosomal storage disorder due to arylsulfatase B enzyme deficiency, leading to progressive multisystem disease and complex airway. Acute respiratory infections can precipitate airway embarrassment. A structured treatment guideline is currently lacking. We present a 7-year-old MPS VI male with respiratory distress, highlighting the challenges in management. Case Presentation: Case review focusing on clinical presentation, imaging findings, and multidisciplinary decision-making during acute deterioration. A child diagnosed with MPS VI at the age of 3.5 years old, due to low arylsulfatase B enzyme activity and homozygous for c.275C>A p.(Thr92Lys) variant in the ARSB gene. At 7 years of age, he showed the signs of dyspnoea, increased respiratory effort with bilateral crepitations, and noisy breathing. Initial management included facemask oxygen, nebulised adrenaline, corticosteroids, and bronchodilators. Computer tomography scan of the neck and chest showed a complex upper airway, multiple tracheal narrowing, tortuosity, and an extra loop of truncus brachiocephalicus from the arch of the aorta. Potential interventions carried substantial risks due to abnormal airway and multisystem disease. Following extensive multidisciplinary discussion after careful consideration of the significant risks associated with invasive airway interventions, a shared decision was reached with the family to adopt a comfort-focused palliative care approach. Despite the best supportive care, the child unfortunately passed away after 3 months. The family was involved in every decision process and was fully supported. Conclusions: MPS VI is associated with complex airways and multisystem disease. Multidisciplinary decision-making with family is critical to safe and appropriate care. The rarity of the disease, lack of guidelines, complex airways, and multiple comorbidities make management challenging. Full article

Schizophrenia has an estimated population prevalence of 1%, but the etiology of this devastating psychiatric condition remains largely uncharacterized. A pronounced genetic component underlies schizophrenia, with heritability estimates ranging from 60% to 80%. Until now, genome-wide association studies have successfully identified 287 distinct genetic loci associated with schizophrenia, but these primarily involve common variants that have minimal individual risk. The recent advent of exome sequencing and genome sequencing has identified ultra-rare sequence variants associated with schizophrenia in familial cases as well as in large cohorts. These studies have implicated multiple gene variants that individually have a large effect size in contributing to schizophrenia. A comparison indicates that these genes exhibit high expression levels in the central nervous system and their protein products participate in many converging pathways encompassing synaptic transmission, glutamatergic neurotransmission, chromatin modification processes, transcriptional regulation, and ubiquitin–proteasome degradation. Although model systems have been established for some genes, most remain to be further studied to identify how gene dysfunction correlates with disease. Full article

Background/Objective: Older patients with end-stage renal disease who receive dialysis often discontinue treatment before the end of their lives. However, the trajectory of family caregiving in this specific context remains under-researched. This study explored the experiences of family members caring for older patients with end-stage kidney disease (ESKD), from the introduction of dialysis to end-of-life care. Methods: This qualitative descriptive study included three family members caring for older patients with end-stage renal disease who were undergoing dialysis in Japan. Data were collected through semi-structured, one-on-one interviews and analyzed using inductive qualitative content analysis within a qualitative descriptive design. Results: The results identified seven categories regarding the family’s experience from dialysis initiation to end-of-life care: Key findings, particularly regarding the terminal phase, included ‘shock of dialysis treatment discontinuation’, ‘last moments shared with the patient’, ‘nostalgic memories of the patient over time, and ‘reflections on end-of-life care for the patient.’ Families described a process wherein the sudden need for proxy decision-making, often without prior discussion, was linked to feelings of regret. Conclusions: The findings describe the continuous experiences of family caregivers in the Japanese context. These exploratory insights suggest that the absence of early Advance Care Planning may contribute to caregiver distress during the withdrawal phase. The results highlight the need for culturally sensitive renal supportive care that fosters communication and understanding of patients’ wishes to mitigate the ethical burdens on families.

Detection of brown spot needle blight (BSNB) disease caused by the fungal pathogen Lecanosticta acicola (Thum.) Syd. has increased significantly at commercial loblolly pine (Pinus taeda L.) plantations across the southeastern United States in recent years. Historically, it has been a serious problem in longleaf pine (Pinus palustris Mill) during the grass stage of seedlings, when the environment is more conducive to fungal infection. However, since 2016, confirmed cases of the disease on loblolly pines have increased in several states, including AL, AR, FL, GA, LA, MS, SC, TN, and TX. We investigated the distribution pattern of confirmed cases of BSNB on loblolly pine between 2016 and 2023, identified site-specific factors, and evaluated the historical standardized precipitation index (SPI) value record over the past four decades. Our results showed that extended periods of above-normal SPI values are associated with BSNB spatial distribution patterns, particularly where the disease has been widely reported in AL, AR, LA, and MS. We observed significant reduction in tree height and dbh in severely infected versus healthy trees at the six study sites evaluated in 2023. Excessive rainfall and prolonged water saturation associated with historical 5-Year SPI values suggest that vulnerable loblolly pine seedlings (depending on genetic family) are more likely to be predisposed to L. acicola infection due to persistent stress from reduced soil nutrient flux and other physiological processes of the host. Understanding the effect of precipitation patterns on cases of BSNB is an important step toward preventing or minimizing the future impact of the disease on commercial plantations in the Southeast.

Membrane curvature is a fundamental biophysical property of cellular membranes that underlies essential processes such as vesicle formation, organelle shaping, intracellular trafficking, and membrane scission. While traditionally studied in the context of cell biology and membrane dynamics, membrane curvature is now emerging as a critical, albeit underrecognized, regulator of oncogenic transformation and tumor progression. Curvature not only governs the mechanical properties of the membrane but also influences the spatial localization and activation of key signaling proteins, including Ras family GTPases, whose oncogenic functions are closely dependent on membrane topology. Cancer is frequently associated with disruptions in the regulation of membrane curvature as a result of aberrant lipid metabolism, overexpression of curvature-modulating proteins, and cytoskeletal remodeling. These changes facilitate the hallmarks of malignancy such as uncontrolled proliferation, enhanced motility, immune evasion, metabolic rewiring, and therapy resistance. Notably, recent evidence reveals that curvature acts as a spatial cue for Ras activation, particularly during epithelial-to-mesenchymal transition (EMT), where curvature-driven Ras relocalization amplifies growth factor signaling and promotes metastasis. This review provides a comprehensive overview of the molecular determinants that generate and sense membrane curvature from lipid shape and membrane asymmetry, BAR domain proteins, and actin dynamics, and explores how these mechanisms are hijacked in cancer. We describe the feedback between membrane architecture and oncogenic pathways such as Ras/MAPK and PI3K/AKT, emphasizing the role of curvature in shaping signal transduction platforms. It should be noted that “curvature-driven signaling” is defined as signaling regulation that arises from membrane-geometry-dependent localization, clustering, or activation of signaling proteins, while “curvature-sensitive platforms” refer to membrane subdomains whose specific curvature selectively recruits and stabilizes signaling complexes. Furthermore, we examine how these biophysical alterations impact vesicular trafficking, organelle morphology, and secretion, all of which are co-opted to support tumor development. From a translational standpoint, we assess emerging therapeutic strategies designed to target curvature-regulating factors and leverage membrane topology for precision drug delivery. Innovations in nanomedicine, super-resolution imaging, and curvature-sensing biosensors are also discussed as tools for both diagnostics and therapeutic monitoring. By integrating advances in membrane biophysics, cancer signaling, and bioengineering, this review highlights membrane curvature as a central and actionable dimension of cancer biology. Full article

Mixograph properties represent important quantitative traits that are controlled by multiple genes and influenced by environmental factors. In this study, we conducted quantitative trait locus (QTL) mapping for key Mixograph paraments using a recombinant inbred line (RIL) population derived from a cross between Yangxiaomai and Zhongyou 9507. Based on a high-density genetic map, six stable QTLs were identified on chromosomes 1A, 1B, and 1D across four environments, with individual phenotypic variation explained, ranging from 2.26 to 28.70%. Among these, QTh.ahau-1A, QMt/QPa.ahau-1B, and QTw.ahau-1D.1 are potentially novel loci. Furthermore, four functional Kompetitive Allele-Specific PCR (KASP) markers were developed based on tightly linked SNPs and validated in 110 advanced breeding lines, confirming their significant association with the target traits and utility for marker-assisted selection (MAS). Additionally, six candidate genes were predicted, which encoded proteins such as a hydroxyproline-rich glycoprotein, a CCCH-type zinc finger protein, protease, kinase, a phosphoglucan water dikinase, and a TRP-like family protein. Collectively, these findings provide valuable genetic loci, functional molecular markers, and candidate gene resources for improving wheat processing quality through MAS-based breeding. Full article

The MADS-box transcription factor (TF) family constitutes a critical class of transcriptional regulators in plants, playing pivotal roles in diverse developmental processes. MIKC-type proteins represent Type II MADS-box TFs that widely function in regulating floral organ development and reproductive growth in plants. In this study, a total of 38 MIKC-type MADS TFs were identified from the sorghum genome, distributed across nine chromosomes. Based on sequence alignments and phylogenetic analysis, these 38 SbMIKC genes (SbMIKCs) were further classified into 10 distinct subfamilies. The expression profiling of these SbMIKCs across multiple tissues revealed five major patterns, among which SbMIKC17 exhibited relatively abundant transcript levels during grain development in sorghum. Further assays confirmed that the protein encoded by SbMIKC17 localizes to the nucleus without self-transactivation activity in yeast. Integrated results from DNA affinity purification sequencing (DAP-seq), dual-luciferase assays, and yeast one-hybrid experiments demonstrate that SbMIKC17 binds to the promoter of SbAGPS1 and activates its activity, as well as enhance the promoter activities of SbBt1, SbGBSSI, SbSSIIa, and SbISA1 simultaneously. Collectively, these findings suggest that the MIKC-type MADS member of SbMIKC17 serves as a potential transcriptional regulator in starch biosynthesis in sorghum. Full article

The PRDM (PR domain-containing) family consists of transcriptional regulators characterized by a PR (PRDI-BF1 and RIZ homology) domain, a subtype of the SET domain, and a variable number of zinc finger motifs. Nineteen PRDM family members have been identified in both mice and humans, and increasing evidence supports their roles as epigenetic regulators in development and disease. PRDM proteins share a conserved structure, comprising an N-terminal PR domain with potential histone methyltransferase activity and C-terminal C2H2-type zinc fingers involved in protein–protein, protein–RNA, and protein–DNA interactions. Recent studies indicate that multiple PRDM family members are involved in the regulation of the neuro-motor system, including neural lineage specification, neuronal differentiation, motor function maintenance, and neuromuscular-related pathological processes. This review summarizes current evidence on the functions and regulatory mechanisms of PRDM family members in the neuro-motor system. Overall, PRDM family members act as important epigenetic regulators in the neuro-motor system. Clarifying their molecular mechanisms may contribute to a better understanding of neuro-motor regulation and provide a theoretical basis for future research in exercise and movement science.

The upscaling of turbines in the offshore wind industry has been unprecedented, as compared to 5–6 MW rated turbines 10 years ago. A typical 20–26 MW rated turbine in modern commercial applications (MingYang MySE 18.X-20 MW installed in 2025 and 26 MW prototype by Dongfang Electric tested in 2025) has been demonstrated. This scaling has been made possible by increasing rotor diameters (>250 m) and hub heights (>150–180 m) to achieve capacity factors of up to 55–65%, annual energy generation of more than 80 GWh/turbine, and significant decreases in levelised cost of energy (LCOE) to current values of up to 63–65 USD 2023/MWh globally averaged in 2023 (with minor variability in 2024 due to market changes and new regional areas). The paper analyses turbine upscaling over three levels of hierarchy, including turbine scale—rated capacity and physical aspect, project scale—multi-gigawatts of farms, and market scale—the global pipeline > 1500 GW level, and combines techno-economic evaluation, structural evaluation of loads, and infrastructure needs assessment. The upscaling has the advantage of reducing the number of turbines dramatically (e.g., 500 to 67 turbines in a 1 GW farm, as turbine size is increased to 15 MW) and balancing-of-plant (BoP) CAPEX (turbine-to-turbine foundations and cables) by some 20 to 30 percent per unit of capacity, and serial production learning rates of between 15 and 18% per doubling of capacity. But the problems that come with the increase in ultra-large designs are nonlinear increments in mass and load (i.e., blade-root and tower-bending moments), logistical constraints (blades > 120 m, nacelle up to 800–1000 tonnes demanding special vessels and ports), supply-chain issues (rare-earth materials, vessel shortages increase day rates by 30–50%), and technology limitations (aeroelastic compounded by numerical differences between reference 5 MW, 10 MW, and 15 MW models), it becomes evident that there is a significant increase in deflections of the tower and blades and platform surge/pitch responses with continued increases in power levels, but without a correspondingly mature infrastructure. The regional differences (mature ports of Europe vs. U.S. Jones Act restrictions vs. scale-up of vessels/manufacturing in China) lead to the necessity of optimisation depending on the context. The analysis concludes that, to the extent of mature markets with adapted logistics, continuous upscaling is an effective business strategy and can result in 5 to 12 percent further reductions in LCOE, but beyond that point, gains become marginal or even negative, as risks and costs increase. The competitiveness of the future depends on multi-scale/multi-market-based approaches—modular-based families of turbines, programmatic standardisation, vibration control innovations, and industry coordination towards supply-chain alignment and standards. Its major strength is that it transcends mere size–cost relationships and shows how nonlinear structural processes, aero-hydro-servo-elastic interactions, and bottlenecks in logistical systems are becoming more determinant of the efficiency of ultra-large turbines. The study demonstrates that upscaling turbines has LCOE benefits through the support of associated improvements in installation facility, supply-chain preparedness, and structural vibration control potential, based on the comparisons of quantitative loads, techno-economic scaling trends, and regional market differentiation.

Relating the standard deviation of time-error buildup, σ_t(T), at some time T after synchronization to a clock’s Allan deviation, σ_y(T), is problematic for several reasons. Notably, the stochastic integrals of various relevant noise types do not exist in closed form, and the standard deviation does not necessarily converge for the noise types of relevance for atomic clocks and crystal oscillators. Consequently, as an expedient, one often writes σ_t(T) = kσ_y(T)T, where k is a constant that depends on the noise type under consideration, as well as the statistical question of interest. Here, we consider the question of Clock Family Time-Error (CFTE) buildup and compute k for noise processes of relevance to atomic timekeeping in space. One of the interesting results of the present work is the k-value that we obtain for flicker frequency noise, which shows a dependence on the time after synchronization. Full article

The tumor suppressor protein p53, encoded by the TP53 gene, is known as the “Guardian of the Genome”, and alterations in TP53 are common to more than 50% of human cancers. p53 is a critical regulator of cellular responses to several stress conditions, such as DNA damage, oncogene activation, and nutrient starvation. p53 was traditionally described as a single transcription factor; however, now it is recognized as a complex family of isoforms generated through alternative promoter usage, alternative splicing, and alternative initiation of translation. These processes give rise to at least 12 distinct p53 isoforms in humans, including p53α (the canonical full-length isoform), p53β, p53γ, Δ40p53, Δ133p53, and Δ160p53, each with unique structural and functional properties. p53 isoforms differ in the presence or absence of specific and fundamental domains located both at N- and C-terminal ends, determining an altered DNA-binding potential, transcriptional activity, and protein–protein interactions. For instance, Δ133p53 isoforms lack part of the N-terminal domains and can exert dominant-negative effects over full-length p53α or modulate alternative transcriptional programs. Similarly, p53β and p53γ isoforms, which have a unique C-termini, influence cellular senescence. The expression patterns of p53 isoforms are tissue-specific and dynamically regulated under both physiological as well as pathological conditions. Alterations of isoform balance have been involved in tumor progression, metastasis, and therapy resistance. Importantly, specific isoforms can either enhance or limit canonical p53 tumor suppressor functions, thereby contributing to the functional diversity of the p53 network. Overall, the p53 isoform landscape adds a critical layer of complexity to p53 biology. In this review, we summarize the mechanisms underlying the production of p53 isoforms, their functions, and their expression in cancer, with the idea that a better understanding of the differential regulation and functional interplay of p53 isoforms may provide novel biomarkers and therapeutic targets in cancer.
