Background: Severe polytrauma is one of the leading causes of death and disability worldwide. Hyperferritinemia is increasingly recognized as a biomarker of critical illness, yet its prognostic significance in polytrauma remains underexplored. This multicenter study investigates the temporal dynamics of serum ferritin in polytrauma patients and its association with systemic inflammation, organ dysfunction, and mortality.

Optic nerve injury leads to axonal degeneration and the death of retinal ganglion cells, which ultimately causes vision loss. Notably, current treatments are limited. In the present study, we explored whether neurogenic differentiation factor 1 (NeuroD1 or ND1) overexpression in retinal Müller cells may repair the retina after optic nerve crush in mice.

Identification of drought-tolerant maize varieties in the context of climate change is critical. Although many studies have reported that the coordination of stomatal and hydraulic conductance of plant leaves ensures the net photosynthetic rate, it is unclear whether the arrangement of these three parameters is consistent among maize varieties differing in drought tolerance. Therefore, in this study, gas exchange parameters, hydraulic properties, and stomatal structure of leaves from eight maize varieties under full and deficit irrigation (DI) were determined.

Background And Objectives: With the widespread integration of digital media into daily life, social media addiction (SMA) has become a growing concern for university students' mental health. Based on attachment theory, this study examined how attachment anxiety and avoidance influence SMA through fear of negative evaluation (FNE) and loneliness.

Methods: A sample of 400 Chinese university students completed the 16-item short version of the Experiences in Close Relationships Scale (ECR), the 8-item Brief Fear of Negative Evaluation Scale (BFNE), the 6-item Revised UCLA Loneliness Scale-Short Form (RULS-6), and the 6-item Bergen Social Media Addiction Scale (BSMAS).

The soil-borne fungal pathogen causes devastating vascular wilt disease in numerous crops, including cotton. In this study, we reveal that , a highly conserved sarcosine oxidase gene, is significantly upregulated during host infection and plays a multifaceted role in fungal physiology and pathogenicity. Functional deletion of leads to increased fungal virulence, accompanied by enhanced microsclerotia formation, elevated carbon source utilization, and pronounced upregulation of effector genes, including over 50 predicted secreted proteins genes.

Objectives: Computed tomography (CT) provides high spatial-resolution visualization of 3D structures for various applications. Traditional analytical/iterative CT reconstruction algorithms require hundreds of angular samplings, a condition may not be met practically for physical and mechanical limitations. Sparse view CT reconstruction has been proposed using constrained optimization and machine learning methods with varying success, less so for ultra-sparse view reconstruction.

Achieving highly efficient syngas conversion to olefins on the Fe-based catalysts is promising, but remains a big challenge due to the twin coexistence of the Fischer-Tropsch to olefins (FTO) and water gas shift (WGS) reactions. Herein, we developed a strategy via regulating the microenvironment of Fe catalyst and controlling the diffusion behaviors of critical intermediates to successfully realize the syngas conversion to olefins with low CO emission. A Fe@C catalyst with Fe species encapsulated in porous carbon was fabricated and achieved high single-pass olefins yield (>30%) and low CO selectivity (around 20%) simultaneously, which has ranked the top among the ever-reported advanced oxide-zeolite, Co-based, and Fe-based catalysts.

Creating high-fidelity 3D head avatars has always been a research hotspot, but it remains a great challenge under lightweight sparse view setups. In this paper, we propose HHAvatar represented by controllable 3D Gaussians for high-fidelity head avatar with dynamic hair modeling. We first use 3D Gaussians to represent the appearance of the head, and then jointly optimize neutral 3D Gaussians and a fully learned MLP-based deformation field to capture complex expressions.

Background: Public health crises such as the COVID-19 pandemic place immense psychological and professional pressure on healthcare workers, particularly those early in their careers. While much research has focused on burnout and stress, fewer studies have examined the role of professional identity and its organizational determinants among actively employed young healthcare professionals.

Methods: This cross-sectional study surveyed 326 young healthcare workers (≤40 years old) across clinical, research, and administrative roles in a megahospital in Shanghai, China.

B cells are central drivers of central nervous system (CNS) autoimmune disorders, including multiple sclerosis (MS). Although the brain meninges normally maintain a stringently non-self-reactive B cell repertoire, how disruption of this local immune tolerance contributes to pathology remains unclear. Here, we demonstrated that autoreactive B cells at the brain border accelerated neuroinflammation by directly engaging encephalitogenic T cells.

Background: Neuroblastoma (NB) is the most common extracranial solid tumor in children, with high-risk NB (HR-NB) exhibiting dismal survival rates due to aggressive biology and therapy resistance. E2F transcription factors (E2Fs) are pivotal regulators of cell cycle progression and immune modulation, yet their prognostic and therapeutic implications in NB remain underexplored.

Methods: Using transcriptomic data from the GEO, TARGET, and E-MTAB-8248 cohorts, we identified E2F-associated molecular subtypes via consensus clustering.

Ferroptosis, an iron-dependent form of regulated cell death characterized by lipid peroxidation, plays a crucial role in acetaminophen (APAP)-induced hepatotoxicity. While 4-octyl itaconate (4-OI) demonstrates protective effects against APAP toxicity, its molecular mechanisms remain to be fully elucidated. Through an innovative integration of untargeted metabolomics and pathway analysis, we unveil a novel dual mechanism by which 4-OI prevents APAP-induced ferroptosis.

Specialized immune cells that reside in tissues orchestrate diverse biological functions by communicating with parenchymal cells. The contribution of the innate immune compartment in the meninges and the central nervous system (CNS) is well-characterized; however, whether cells of the adaptive immune system reside in the brain and are involved in maintaining homeostasis is unclear. Here we show that the subfornical organ (SFO) of the brain is a nucleus for parenchymal αβ T cells in the steady-state brain in both mice and humans.

Global change has dramatically altered the Earth's biogeochemical cycles. However, the interactive effects of multiple global change factors (GCFs) on terrestrial nitrogen (N) cycling worldwide remain unclear, limiting the ability to predict how future global change will affect the global N cycle. We conducted a meta-analysis of 108 published articles to evaluate the main and interactive effects of elevated CO, N addition, warming, and altered precipitation on soil N pools (NH , NO , and organic N) and transformation rates (N mineralization, nitrification, and denitrification) across terrestrial ecosystems.
