The purpose of this study is to explore the effect of physical activity on the executive function of 5-6-year-old children and to provide a theoretical and empirical basis for further research on improvements in the executive function of children caused by physical activity. A total of 170 children (5-6 years old) from several kindergartens were selected via multistage stratified sampling. All the children wore 7-day accelerometers (ActiGraph GT3X) to measure their daily physical activities. Parents completed the preschool children's executive function questionnaire (BRIEF-P) to assess their daily executive function. (1) The total duration of physical activity (TPA) was 110.84 ± 22.52 min/day, the duration of low-intensity physical activity (LPA) was 36.23 ± 7.53 min/day, and the duration of medium- and high-intensity physical activity (MVPA) was 74.55 ± 16.77 min/day. A total of 82.6% of the children reached the recommended amount of MVPA. (2) After adjusting for body mass index (BMI), parents' highest educational background and parents' total monthly income, MVPA was negatively correlated with children's total executive function score ( Physical activity can improve the executive function of children aged 5-6 years to some extent. MVPA can improve children's executive function and subdomains, and there is a correlation between boys' physical activity and executive function. Show less

This study aimed to identify heterogeneous patterns of medical coping modes (MCM) and to examine the moderating role of social support in the relationship between these patterns and social disability in young and middle-aged patients after percutaneous coronary intervention (PCI). A cross-sectional study was conducted among 129 post-PCI patients from a single center in China. Participants completed the Medical Coping Modes Questionnaire (MCMQ), the Social Support Rating Scale (SSRS), and the Social Disability Screening Schedule (SDSS). Latent profile analysis (LPA) was used to identify distinct coping patterns. The moderation effect of social support was tested using the Johnson-Neyman technique. Two distinct coping profiles were identified via LPA: "Adaptive Copers" (55.1%), characterized by higher confrontation and lower avoidance/resignation, and "Maladaptive Copers" (44.9%), showing the opposite pattern. A counterintuitive finding emerged, with the Maladaptive Copers reporting significantly lower social disability scores. Furthermore, beyond this profile differentiation, social support demonstrated a significant U-shaped moderating effect in the coping-disability relationship. Its moderating role was statistically significant only at very low (<39.884) and very high (>52.924) levels of support. This study reveals two key findings: first, post-PCI patients are heterogeneous in coping, comprising adaptive and maladaptive subgroups; second, the impact of these coping styles on social disability is non-linearly moderated by social support. Clinicians should assess both coping profiles and social support levels to tailor interventions effectively. Show less

Older adults' physical and sensory function and self-perceived health state are associated with their daily health behavior, such as moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), sedentary behavior (SEB), and sleep duration (SD), though most studies examine these independently, overlooking 24-hour interactions. This study aims to investigate the relationships between physical and sensory function (vision, hearing, activity limitations), self-perceived health and the pattern of 24-hour activity behaviors via compositional data analysis. A secondary data analysis was conducted on data from the Survey of Health, Ageing and Retirement in Europe. Compositional data analysis was employed to account for the inherently interdependent nature of these behaviors. Linear regression models were implemented, designating activity behaviors as the dependent variable and sensory/physical function as the independent variable. The results indicated that vision and hearing showed weaker and nonsignificant associations with activity behaviors. Activity limitations significantly influence health behavior patterns, with no limitations associated with more time in MVPA and less time in SEB and SD. Self-perceived health is significantly positively associated with more MVPA, while inversely associated with SEB and SD. This study revealed that older adults with limitations in their daily activities showed the most sedentary daily activity pattern. Future research should develop targeted interventions to improve activity behaviors in this population. Show less

This study aimed to assess the prognostic significance of serum lipoprotein(a) [Lp(a)] levels regarding overall survival (OS) and progression-free survival (PFS) among patients diagnosed with pancreatic cancer (PC). A retrospective cohort of 364 pathologically confirmed PC patients treated at the Affiliated Hospital of Qingdao University between January 2019 and December 2022 was analyzed. The optimal cutoff for Lp(a) was identified using X-tile software, allowing categorization into high and low Lp(a) groups. To minimize selection bias, propensity score matching (PSM) was utilized. Survival outcomes were compared using Kaplan-Meier curves and log-rank tests. Cox proportional hazards models were applied to identify independent prognostic variables affecting OS and PFS. Patients with high Lp(a) had significantly shorter OS and PFS both before and after PSM (post-PSM OS: 12.28 vs. 27.67 months, P = 0.003; PFS: 7.00 vs. 11.30 months, P = 0.002). Multivariate Cox analysis confirmed high Lp(a) as an independent predictor of poor OS [HR = 2.11 (1.17-3.81), P = 0.013] and PFS [HR = 2.14 (1.20-3.83), P = 0.010]. In the surgical subgroup (n = 215), high Lp(a) was also associated with worse OS (16.43 vs. 35.47 months, P = 0.02) and PFS (8.40 vs. 11.77 months, P = 0.036). Multivariate analysis in this subgroup showed that high Lp(a) remained an independent risk factor for OS [HR = 2.82 (1.36-5.87), P = 0.006] and PFS [HR = 2.01 (1.06-3.86), P = 0.034]. Elevated serum Lp(a) is an independent predictor of reduced OS and PFS in patients with pancreatic cancer. In contrast to conventional lipid profiles, the genetic stability of Lp(a) makes it a reliable baseline prognostic marker. Show less

Amyloid transthyretin (ATTR) amyloidosis is a rare, life-threatening disease frequently manifesting with cardiomyopathy (ATTR-CM), polyneuropathy (ATTR-PN) or both (ATTR-mixed). We retrospectively analysed US electronic health records and claims data to provide up-to-date estimates of ATTR amyloidosis epidemiology (overall and by phenotype). Data were extracted from the Clarivate Real-World Data repository (2016-2023). Given the lack of established coding for ATTR amyloidosis, we used different combinations of diagnostic codes to obtain narrow and broad estimates of incident and prevalent cases in the USA in 2022. Temporal trends (2019-2022) were also assessed. Using narrow definitions, the 2022 estimated incidence of ATTR amyloidosis overall, ATTR-CM, ATTR-PN and ATTR-mixed was 16.6, 12.7, 3.5 and 1.9 cases per million people, respectively; the corresponding prevalence estimates were 59.8, 41.1, 15.1 and 9.8 cases per million people. Estimates were consistently lower with the narrow (vs broad) definitions. Over time, the incidence and prevalence of ATTR amyloidosis overall increased, driven by ATTR-CM cases. No major changes were reported for the other phenotypes. This study provides comprehensive and up-to-date epidemiological data for ATTR amyloidosis in the USA. Our findings corroborate the need for appropriate differential diagnostic coding and standardised criteria. Show less

The objective of this study was to explore the longitudinal relationship between the volume and intensity of physical activity (PA) and their combined risk for cognitive impairment (CI). The study included 10,174 participants from the 2011-2018 CHARLS cohort. Pennsylvania and CI were assessed using self-reported questionnaires. Statistical analyses were performed using the Cox regression model. After adjusting for all covariates, the risk of CI was 14% lower in subjects with physical activity volume (PAV) ≥600 Metabolic Equivalent of Task (MET)-min/week compared to those with insufficient PA (HR: 0.86). The risk was reduced by 38% for subjects with PAV of 1800-2999 MET-min/week (HR: 0.62). Regarding the intensity of PA, the risk of CI was reduced by 25% for a proportion of 0.25-0.5 of (moderate to vigorous PA) MVPA to PAV (HR: 0.75) compared to a proportion of 0-0.25. Regardless of PAV, the risk of CI was lowest when the proportion of moderate to vigorous PA(MVPA) to PAV was 0.25-0.5, and 0.5-0.75 for the proportion of light-intensity physical activity (LPA) to PAV. The PAV 1800-2999 MET-min/week and maintaining a proportion of LPA to PAV of 0.5-0.75, or a proportion of MVPA to PAV of 0.25-0.5, are more effective in reducing the risk of CI. Policy implications should prioritize tailored physical activity strategies for individuals over 65, emphasizing low-intensity activities, safe high-intensity training, and the development of accessible urban facilities, in line with WHO guidelines.

Problematic smartphone use (PSU) has become a growing concern among young populations, raising significant issues for their physical and psychological well-being. Guided by Compensatory Internet Use Theory and the Interaction of Person-Affect-Cognition-Execution (I-PACE) model, this study examined the associations between different forms of childhood trauma and PSU. Participants were 2717 college students (661 males, 22.49%; Mage = 19.81 years). Two chain mediation models were tested, and latent profile analysis (LPA) was employed to capture individual differences from a person-centred perspective. LPA revealed three distinct trauma profiles: low childhood trauma, moderate childhood abuse, and high childhood abuse. Across both variable-centred and person-centred ap-proaches, rumination and social anxiety were identified as mediators linking childhood trauma to PSU. These findings advance understanding of the pathways through which childhood trauma contributes to PSU in college students. By integrating variable- and person-centred approaches, the study highlights the importance of cognitive-emotional mechanisms and provides implications for targeted prevention and intervention strategies.

This study aims to identify heterogeneous subgroups of first-year residents experiencing transition shock using latent profile analysis (LPA) and to explore the predictive effects of various dimensions of professional identity on different transition shock types. A multi-center, cross-sectional design was employed. From September 2023 to August 2024, a total of 766 first-year residents were selected via cluster sampling from four national-level training bases in Hubei Province, China, for a cross-sectional survey. The survey was conducted using the revised Transition Shock Scale (Cronbach's A total of 574 valid questionnaires were returned. Latent profile analysis identified three latent classes: a low psychological-sociocultural shock group (13.41%, Transition shock among first-year residents exhibits significant heterogeneity. These findings provide evidence for developing targeted intervention strategies. Higher levels of professional cognition, commitment, and expectation are associated with lower levels of transition shock. However, a strong sense of professional values is associated with higher transition shock, a relationship potentially mediated by an idealism-reality gap. It is recommended that tiered competency-building interventions should be implemented for the high physical-knowledge/skill shock group, and a dual-track support system should be designed for Master of Medicine degree candidates.

Nutritional care is essential in the treatment of critical patients, and the nutritional care competence among ICU nurses is a crucial skill in clinical practice of nutritional care for critically ill patients. Although previous studies have investigated the nutritional care competence of nursing staff, the investigation and heterogeneity analysis of nutritional care competence among ICU nurses in China are lacking. To investigate the current status of nutritional care competence among ICU nurses through latent profile analysis, identify potential subgroups and their population characteristics, and explore the factors that influence the potential subgroups. A cross-sectional and multi-center study of 561 ICU nurses in Anhui province was selected by convenience sampling method and surveyed with general information questionnaire and nutritional care competence scale for clinical nurses. Latent profile analysis (LPA) was used to identify potential subgroups among the nurses based on their competence in nutritional care. Logistic regression analysis was used to explore the factors associated with membership in different latent profiles. The nutritional care competence among ICU nurses in Anhui Province was at an intermediate level and was categorized into three potential groups through latent profile analysis: low nutritional care competence group (31.73%), medium nutritional care competence group (48.84%), and high nutritional care competence group (19.43%). The results of logistic regression analyses showed that number of night shifts per month, job satisfaction, received regular nutritional care supervision, attended nutrition-related training, and received nutrition course education were the influencing factors of potential categories among ICU nurses’ nutritional care competence ( The nutritional care competence categorical characteristics among ICU nurses exhibit individual heterogeneity and could be categorized into three potential profiles. Nursing administrators should promptly identify and carry out targeted interventions according to the characteristics of nurses in different profiles to improve the overall quality of nutritional care.

Robotic technology is transforming healthcare by delivering more precision, convenience, and efficiency, as seen in applications like blood collection robots. However, the full potential of such innovations hinges critically on patient acceptance. To systematically understand the drivers of intention to use, the concept of technological readiness-an individual's stable propensity to embrace new technologies-provides a valuable lens. Nevertheless, the demographic profile of technological readiness and its specific relationship with the intention to use nursing robots remain underexplored. This study aimed to identify profiles of technology readiness among patients, analyze the factors influencing these profiles, and investigate the relationship between different profiles and the intention to use blood collection robots. In this study, data on technology readiness and intention to use were collected from 331 patients between December 2024 and February 2025 through a cross-sectional survey. Latent profile analysis (LPA) was employed to assess population heterogeneity in patients' technology readiness, whereas logistic regression analysis was applied to identify factors associated with the intention to use blood collection robots. Potential profiling revealed three distinct technology readiness populations: conservative avoiders (47.7%), ambivalent adopters (18.5%), and active adopters (33.8%). The results of the three-profile classification are related to the intention to use blood collection robots. The results clearly show that the intention to use the blood collection robot by patients belonging to conservative avoiders (profile 1) was weaker and statistically significant than both active adopters (profile 3) and ambivalent adopters (profile 2). While profile 2 has a high intention to use, it also has a high level of insecurity and discomfort. Interestingly, the group of patients with low education levels is more likely to be attributed to active adopters. The results of the multiple regression analysis on patients' intention to use revealed significant differences in education level, experience with robots, and potential profiles. This study reveals the complex psychological characteristics of patient groups when encountering new technologies and their potential relationship with intention to use nursing robots. This suggests that clinical practice should account for patient heterogeneity from standardized procedures to a patient-centered approach. Targeted measures should be proposed to enhance the efficiency of technology implementation and improve patient experience. Show less

The association between exercise behaviors-including physical activity (PA), light-intensity PA (LPA), moderate-to-vigorous-intensity PA (MVPA), sedentary behavior (SB), and sleep-and muscle quality remains unclear. This study aimed to examine the association between 24-h movement behaviors and muscle quality, as assessed by bioelectrical impedance spectroscopy (BIS). A total of 294 participants were enrolled in the cross-sectional study. LPA, MVPA, and SB were objectively measured using a tri-axial accelerometer. Sleep duration was assessed through a validated self-reported questionnaire. Muscle quality, based on electrical properties, was evaluated using a BIS device including parameters such as phase angle, intracellular-to-extracellular water ratio, membrane capacitance, characteristic frequency. Associations between 24-h movement behaviors and muscle quality derived from electrical properties were examined using compositional multiple linear regression. Additionally, hypothetical time reallocations among different movement behaviors in relation to muscle quality were evaluated using compositional isotemporal substitution. The same analyses were also conducted among participants classified as non-regular exercisers. Longer durations of MVPA were significantly associated with better indicators of muscle quality. Theoretical time reallocation analyses suggested that 30 min from SB, LPA, or sleep to MVPA was associated with approximately 0.5-3.8% higher values of BIS-derived muscle quality indices. This association remained consistent among non-regular exercisers. These cross-sectional findings indicate that greater daily MVPA is associated with a more favorable BIS-derived muscle-quality profile. MVPA is a key component of daily movement that contributes to the maintenance and potential improvement of muscle quality, as evaluated through electrical properties measured using BIS in both regular and non-regular exercisers.

Pyoderma gangrenosum (PG) is a rare, noninfectious, truly nongangrenous, autoinflammatory condition marked by neutrophilic dermatosis. It is characterized by the rapid onset of painful, full-thickness, ulcerative skin lesions with distinctive violaceous and undermined borders. PG is commonly associated with autoimmune and hematologic disorders, namely, inflammatory bowel disease (IBD) and monoclonal gammopathy of undetermined significance (MGUS). However, it has less commonly been reported in association with lymphoplasmacytic lymphoma (LPL) and rarely with its subtype, Waldenström macroglobulinemia (WM). This case unfolds the story of a 72-year-old female patient with a complex medical and primarily cutaneous oncological history, who initially developed painful lesions on her shins suspected to be PG with a superimposed infection. During extensive infectious, rheumatologic, and oncologic workup revealing an IgM monoclonal gammopathy and antibiotic-resistant infections, her condition quickly deteriorated with altered mental status and eventual cardiopulmonary arrest 2 months after the initial PG diagnosis. This case highlights the importance of close follow-up after PG identification for unusual underlying malignancies and suggests that even an indolent malignancy like WM can contribute to aggressive clinical decline in this setting.

Genetics increasingly comes to the front with early-onset cardiovascular disease (CVD) since researchers investigate the complex interplay of hereditary factors that promote an early manifestation of the disease. CVD is one of the most general causes of morbidity and mortality worldwide, presenting unique challenges when it arises in younger populations many times due to genetic predispositions. The various etiologies in the pathogenesis of early-onset CVD involve genetic factors, including the monogenic disorders of familial hypercholesterolemia (FH) and hypertrophic cardiomyopathy (HCM) of these diseases showing the simple Mendelian patterns of inheritance. These may be mediated through gene variations, including Low-Density Lipoprotein Receptor (LDLR), Apolipoprotein B (APOB), Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9), and Myosin Heavy Chain 7 (MYH7). Disrupted lipid metabolism, myocardial function, or vascular integrity due to mutations could lead to adverse clinical consequences. Moreover, polygenic risk score (PRS) has now become helpful in identifying individuals who are at elevated risk due to the cumulative effect of several genetic variants. Knowledge about gene-environment interactions, epigenetic influences, and complex regulatory networks contributes to understanding the importance of genetic contributions to early-onset CVD. However, the genetic variation is population-specific and underlines the need for research inclusive of diverse genetic backgrounds in developing more inclusive and effective predictive models. Whole genome and exome sequencing have revolutionized early detection, making personalized treatment plans possible, including targeted therapeutic interventions like PCSK9 inhibitors. On the other hand, such scientific progress also provides a lot of ethical challenges, such as utilizing personal data, informed consent, and equal access to genetic services. This review summarizes the genetic basis underlying early-onset CVD, with detailed discussions of monogenic and polygenic contributions, important genetic pathways, and emerging advances in genetic testing and personalized medicine approaches. By highlighting the integration of genetic insights with preventive and therapeutic strategies, this review aims to bring into focus the use of genetic insight in the betterment of outcomes in patients and inform future research in cardiovascular genetics.

Senescence, a state of permanent cell cycle arrest, is a complex cellular phenomenon closely affiliated with age-related diseases and pathological fibrosis. Cellular senescence is now recognized as a significant contributor to organ fibrosis, largely driven by transforming growth factor beta (TGF-β) signaling, such as in metabolic dysfunction-associated steatohepatitis (MASH), idiopathic pulmonary fibrosis (IPF), chronic kidney disease (CKD), and myocardial fibrosis, which can lead to heart failure, cystic fibrosis, and fibrosis in pancreatic tumors, to name a few. MASH is a progressive inflammatory and fibrotic liver condition that has reached pandemic proportions, now considered the largest non-viral contributor to the need for liver transplantation. We previously studied Oxy210, an anti-fibrotic and anti-inflammatory, orally bioavailable, oxysterol-based drug candidate for MASH, using APOE*3-Leiden.CETP mice, a humanized hyperlipidemic mouse model that closely recapitulates the hallmarks of human MASH. In this model, treatment of mice with Oxy210 for 16 weeks caused significant amelioration of the disease, evidenced by reduced hepatic inflammation, lipid deposition, and fibrosis, atherosclerosis and adipose tissue inflammation. Here we demonstrate increased hepatic expression of senescence-associated genes and senescence-associated secretory phenotype (SASP), correlated with the expression of pro-fibrotic and pro-inflammatorygenes in these mice during the development of MASH that are significantly inhibited by Oxy210. Using the HepG2 human hepatocyte cell line, we demonstrate the induced expression of senescent-associated genes and SASP by TGF-β and inhibition by Oxy210. These findings further support the potential therapeutic effects of Oxy210 mediated in part through inhibition of senescence-driven hepatic fibrosis and inflammation in MASH and perhaps in other senescence-associated fibrotic diseases.

This study investigated the brain functional characteristics of patients with neuropathic pain (NP) following spinal cord injury (SCI) using functional near-infrared spectroscopy (fNIRS). A total of 35 subjects were enrolled, including 10 able-bodied controls, 12 patients with SCI and NP (SCI-NP), and 13 patients with SCI (without NP). fNIRS was used to detected blood oxygen signals during motor tasks and resting-state (RS) functional connectivity (FC) in the subjects. We also performed Pearson correlation analyses of pain scores (NPS) and the Pittsburgh Sleep Quality Index (PSQI) in patients with SCI-NP. Statistical analyses were performed using Shapiro-Wilk test for normality; paired During the task state, patients with SCI-NP activated bilateral primary somatosensory cortex (S1, L/R Patients with SCI-NP exhibit significant abnormal cerebral cortical excitation and reduced FC.

Using growth curves to evaluate proliferative and scratch assays to determine migrative capacities of the cells, in normal fibroblasts as well as in osteosarcoma-derived cells, we demonstrate that the modified Spry4 Show less

There is a lack of comprehensive understanding concerning the variations in cardiometabolic parameters due to the interactions between dietary habits and Lipoprotein lipase (LPL) gene polymorphisms. This study aimed to investigate how primary dietary patterns relate to the Rs320 variant of the LPL gene and their impact on the cardiometabolic profile in a group of Iranian adults. This cross-sectional study involved 387 adults in Yazd, Iran, ranging in age from 20 to 70. Following an assessment of the inclusion and exclusion criteria, participants in the Yazd Health Study (YaHS) enrollment phase were chosen. In the present study, the major dietary patterns were identified using factor analysis method. The polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) method was used to identify rs320 variant on LPL gene. General linear models (GLM) were applied to evaluate how dietary patterns interact with rs320 polymorphism to influence cardiometabolic markers. Three major dietary patterns were identified: western, healthy, and traditional. The allele distributions of rs320 were 66.5% for T and 33.5% for G. The prevalences of the genotypes were 57.90% ( The online version contains supplementary material available at 10.1038/s41598-025-27399-7. Show less

Ankylosing spondylitis (AS) is a chronic and progressive inflammatory arthritis involving disorders of both the immune and skeletal systems. Multiple osteochondromas (MO) is a rare skeletal disorder with a variety of clinical manifestations characterized by multiple benign exostoses. Here, we investigate a Chinese family with HLA-B27-negative AS complicated with MO. Whole-exome sequencing (WES) and Sanger sequencing were used to screen and identify the pathogenic gene. In vitro functional analysis was performed, and a pathogenesis-associated interleukin (IL)-17 receptor C (IL17RC) mutation was analyzed to investigate its effect on phenotypes. WES was used to identify a known missense mutation, NM₀₀₀₁₂₇.3:c.1019 G > A(p.Arg340His), in the pathogenic gene EXT1 that is causal for MO. Moreover, a missense mutation, NM₁₅₃₄₆₁.3:c.1067 C > T(p.Thr356Met), in the IL17RC gene was identified as potentially responsible for AS or spondyloarthritis symptoms in this family. In vitro over-expression of mutant IL17RC decreased its expression and increased the expression of IL17RA, consistent with the expression of these two genes in patients. Mechanistically, mutant IL17RC enhanced the activation of the NF-κB pathway. This study increases our understanding of the pathogenesis and progression of these diseases. Our findings broaden the risk factors in non-HLA-B genes associated with the NF-κB pathway in AS. Show less

Major depressive disorder (MDD) is a complex psychological disorder with a sophisticated molecular etiology. Although its connection with fibroblast growth factor receptor 1 (FGFR1) in the hippocampus is known, the precise mechanisms underlying its pathophysiology remain unclear. Here we conduct a comprehensive analysis of the molecular profile of the hippocampus in patients with MDD. We identified a distinct overexpression of FGFR1 specifically within the dentate gyrus of patients with MDD. Through the use of optogenetic techniques for the in vivo spatiotemporal dissection of FGFR1 signaling, we uncovered a sequential FGFR1-Notch-brain-derived neurotrophic factor (BDNF) pathway within the dentate gyrus, which can ultimately induce adult hippocampal neurogenesis, significantly contributing to antidepressant effects. We discovered that the dysregulation of this axis by the protein Numb, which demonstrates an age-related increase in individuals with MDD, is closely associated with the development of depressive phenotypes. Remarkably, targeting Numb to restore this axis effectively reversed the depressive phenotype, thus offering new insights into potential therapeutic strategies. Show less

Intensive poultry farming has significantly increased the incidence of lipid metabolic disorders, severely compromising the economic benefits of poultry industry. Currently, gamma-aminobutyric acid (GABA) is primarily used to mitigate adverse effects of heat stress in poultry, while the effects and mechanisms of GABA on lipid metabolism disorders remain underexplored. Lactobacillus plantarum (L. plantarum) serves as a significant source of GABA and is widely used in the livestock industry. This study therefore examines the effects of postbiotic GABA and the GABA-producing probiotic L. plantarum 1-2-3 on abdominal adipose tissue of laying hens following corticosterone-induced stress. To this end, hens subjected to corticosterone subcutaneous injections (4 mg/kg of body weight) were respectively received GABA (100 mg/kg BW) or L. plantarum 1-2-3 (1 × 10⁹ CFU/day). Results demonstrated that both GABA and L. plantarum 1-2-3 alleviated corticosterone-induced lipid metabolism disorders and reduced adipocyte size in abdominal fat. Additionally, expression analyses of genes and proteins related to lipid metabolism (PPARγ, C/EBPα, CD36, LPL, ATGL, and HSL) further showed that GABA and L. plantarum 1-2-3 inhibited excessive deposition of abdominal lipids in laying hens by suppressing adipogenesis and lipogenesis, while promoting lipolysis. Moreover, GABA and L. plantarum 1-2-3 both mitigated lipid deposition-induced inflammation and oxidative damage by normalizing macrophage infiltration and improving antioxidative enzyme activities (GSH-Px, T-SOD, CAT). These findings demonstrate the efficacy of GABA and L. plantarum 1-2-3 in alleviating lipid metabolism disorders in the abdominal adipose tissue of laying hens, suggesting their promise as nutritional supplements for counteracting stress-induced metabolic dysfunction.

Adipogenic differentiation of adipose-derived stem cells (ADSCs) is fundamental to both adipose tissue homeostasis and clinical applications, particularly fat grafting. However, the global and stage-specific transcriptional regulatory networks underlying ADSC adipogenesis remain incompletely elucidated. In this study, we integrated bulk and single-cell RNA-seq datasets across multiple time points of ADSC adipogenesis to identify core regulators of differentiation and maturation. A total of 41 genes were consistently upregulated during early differentiation, among which eight hub genes (FABP4, FASN, FABP5, ADIPOQ, PLIN1, LPL, CIDEC, and ACSL1) formed a tightly connected protein-protein interaction (PPI) module associated with lipid metabolism, lipid droplet formation, and adipocyte maturation. Further integration of differentially expressed lncRNAs and miRNAs led to the construction of a ceRNA network involving 7 mRNAs, 9 miRNAs, and 4 lncRNAs, comprising 34 predicted lncRNA-miRNA-mRNA regulatory axes. To identify temporal transcriptional regulators, we defined five genes (TTC14, MBNL2, UBR3, ABCD2, and SORT1) as early-stage inducers of adipogenesis, and four genes (UQCR11, NDUFB4, S100A10, and PRDX3) as late-stage regulators involved in maintaining the mature phenotype. These stage-specific regulators showed distinct temporal expression patterns and were validated by qPCR. GeneMANIA network analysis further revealed that early-stage regulators were enriched in lipid transport and lipase activity regulation, while late-stage regulators were associated with mitochondrial electron transport and energy metabolism. These findings highlight the stage-dependent transcriptional landscape of ADSC adipogenesis and provide candidate regulatory targets for modulating adipocyte differentiation and stability. Show less

Acute Respiratory Distress Syndrome is a lung disorder defined by the acute onset of hypoxemia, the commonest being abdominal sepsis.Many biomarkers have been studied for diagnostic prognostication and ARDS pharmacotherapy. The current study aim to assess the protective effects of UFH versus Enoxaparin in sepsis-induced ARDS and related metabolic sequelae. Sepsis was initiated through cecal ligation and puncture (CLP). Wistar rats were divided to: sham, CLP, CLP + unfractionated Heparin, and CLP + Enoxaparin and CLP + distilled water groups. Levels of serum Lipoxin A4 (LXA4), lipoprotein lipase (LPL), leukotriene E4 (LTE4), leukotriene B4 (LTB4), interleukin-8 (IL-8), were quantified. Furthermore, mRNA expression of receptors for advanced glycation end products (RAGE) and angiopoietin-2 (ANG-2) were assessed. Histopathological study was conducted to assess any lung injuries. Septic rats demonstrated higher levels of leukotriene E4, leukotriene B4, and interleukin-8, while treatment with unfractionated Heparin attenuated these levels but enoxaparin effectiveness on LTB-4 and IL-8 was not as significant as heparin while its was equally effective on LTE-4. Moreover, mRNA levels of RAGE and ANG-2 were enhanced in CLP rats. These elevations were mitigated by treatment with unfractionated Heparin and reduced by enoxaparin to a lesser extent. Treatment with unfractionated Heparin increased the lipoxin A4 and lipoprotein lipase levels but enoxaparin had no effect on the LPL level. Lung protective effect of unfractionated Heparin was further confirmed by histopathological observations of lung tissue samples. Our study demonstrates that UFH can modulate ARDS and metabolic dysfunction in hyperinflammatory conditions like sepsis. Show less

In this functional magnetic resonance imaging study, we investigated whether language production and understanding recruit similar phoneme-specific networks. We did so by comparing the brain's response to different phoneme categories in minimal pairs: Bilabial-initial words (eg "monkey") were contrasted to alveolar-initial words (eg "donkey") in 37 participants performing both language production and comprehension tasks. Individual-specific region-of-interest analyses showed that the same sensorimotor networks were activated across the language modalities. In motor regions, word production and comprehension elicited the same phoneme-specific topographical activity patterns, with stronger haemodynamic activations for alveolar-initial words in the tongue cortex and stronger activations for bilabial-initial words in the lip cortex. In the posterior and middle superior temporal cortex, production and comprehension likewise resulted in similar activity patterns, with enhanced activations to alveolar- compared to bilabial-initial words. These results disagree with the classical asymmetry between language production and understanding in neurobiological models of language, and instead advocate for a cortical organization where phonology is carried by similar topographical activations in motor cortex and distributed activations in temporal cortex across the language modalities.

Traumatic brain injury (TBI) represents a major cause of mortality and disability worldwide, particularly affecting young adults and elderly populations. This study investigates the neuroprotective potential of orlistat (ORL), a gastrointestinal lipase inhibitor, in a murine TBI model. Behavioral, histological, and molecular analyses demonstrated that ORL significantly attenuated TBI-induced neurological damage. Microglial depletion experiments revealed that ORL's neuroprotective effects were largely mediated through microglial modulation. In vitro and in vivo studies showed that ORL suppressed microglial activation, phagocytosis, and migration. Single-cell RNA sequencing identified upregulation of lipoprotein lipase (LPL) in a TBI-induced microglial subpopulation. Molecular docking predicted ORL-LPL binding, suggesting direct enzymatic inhibition. Transcriptomic and metabolomic analyses further revealed ORL's modulation of microglial metabolic pathways and inflammatory responses. Our findings position ORL as a promising repurposed therapeutic for TBI through its novel mechanism of targeting microglial LPL-mediated neuroinflammation. Show less
