Background And Hypothesis: Given that fixation stability is closely linked to cognition, we investigated fixation stability in patients at different stages of schizophrenia, its relationship with cognitive impairments, and its predictive role for conversion to psychosis.

Study Design: Fixation stability was measured by bivariate contour ellipse area (BCEA), and cognition was assessed by the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery for 75 patients with first-episode schizophrenia (FES), 75 patients with clinical high-risk (CHR) syndrome, and 75 healthy controls (HCs). After a 1-year longitudinal study, CHR follow-up outcomes were classified as CHR-converters and CHR-nonconverters.

Achieving strong adhesion under wet and bleeding conditions remains a major challenge for medical adhesives. Existing strategies that utilize polymer chain penetration to overcome this have shown promise but typically rely on complex external stimuli, limiting clinical use. Here, MonoSeal is introduced, a body-fluid-triggered adhesive sponge composed of a single oxidized polysaccharide, operating via a newly proposed mechanism termed Autopenetrative Adhesion (APA).

Current approaches for bone repair predominantly target localized delivery of growth factors that are aimed at the coupling of angiogenesis and osteogenesis. However, delayed revascularization and regeneration of critical-sized bone defects are still challenging. In this study, we engineer an ossification center-like organoid (OCO) that consist of an inner-core bone morphogenetic and neurotrophic spheroid generated via MSCs-loaded 3D printing, alongside the interstitially distributed outer-shell proangiogenic neurotrophic phase.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive lung disorder marked by deteriorating dyspnea and declining pulmonary function. Despite its rising prevalence and incidence, therapeutic options remain limited. PTEN-induced kinase 1 (PINK1), known for its role in PINK1/Parkin-dependent mitophagy, contributes to the pathogenesis of various lung diseases.

Osteochondral defect regeneration is challenging due to the mismatch between cartilage and subchondral bone. We developed a functionalized scaffold replicating the natural architecture, biochemical and biomechanical environment of both tissues to promote concurrent regeneration. Our bilayered, zone-specific scaffold combines tailored materials for each tissue type: gelatin methacryloyl (GelMA), modified hyaluronic acid, and umbilical cord-derived extracellular matrix (ECM) for the cartilage layer; GelMA, placenta-derived ECM, and nano amorphous calcium phosphate for the osseous layer.

Atomic layer deposition (ALD) is notable for highly controlled syntheses of ultrathin materials through self-limiting reactions. However, ALD materials have strong bonding interactions with substrates, which have generally made substrate removal for the preparation of freestanding large-area 2D films challenging. Here, we report a strategy for the fabrication of freestanding, amorphous ultrathin films by growing on single-crystal NaCl.

Label-free surface-enhanced Raman spectroscopy (SERS) is capable of capturing rich compositional information from complex biosamples by providing vibrational spectra that are crucial for biosample identification. However, increasing complexity and subtle variations in biological media can diminish the discrimination accuracy of traditional SERS excited by a single laser wavelength. Herein, we introduce a multiwavelength SERS approach combined with machine learning (ML)-based classification to improve the discrimination accuracy of human urine specimens for bladder cancer (BCa) diagnosis.

Interactions between bacteria and cyanobacteria influence the occurrence and development of harmful cyanobacterial blooms (HCBs). Bloom-forming cyanobacteria and cyanotoxin-degrading bacteria are essential in HCBs, nonetheless, their interactions and the underlying mechanisms remain unclear. To address this gap, a typical microcystin-LR (MC-LR)-degrading bacterium and a toxic Microcystis aeruginosa strain were co-cultivated to investigate their interactions.

Although natural polymers have been widely used in constructing bone scaffolds, it still remains challenging to fabricate natural polymer-derived bone scaffolds with biomimetic mechanical properties as well as outstanding osteogenic properties for large-size and weight-bearing bone defects regeneration. Herein, an "organic-inorganic assembly" strategy is developed to construct silk fibroin (SF)-based bone scaffolds with the aforementioned merits. After secondary structure reshuffling, the 3.

Label-free surface-enhanced Raman spectroscopy (SERS) has attracted extensive attention as an emerging technique for molecular phenotyping of biological samples. However, the selective enhancement property of SERS mediated by complicated interactions between substrates and analytes is unfavorable for molecular profiling. The electrostatic force is among the most dominating interactions that can cause selective adsorption of molecules to charged substrates.

Idiopathic pulmonary fibrosis (IPF) is an irreversible, fatal interstitial lung disease lacking specific therapeutics. Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme of the nicotinamide adenine dinucleotide (NAD) salvage biosynthesis pathway and a cytokine, has been previously reported as a biomarker for lung diseases; however, the role of NAMPT in pulmonary fibrosis has not been elucidated. We identified the NAMPT level changes in pulmonary fibrosis by analyzing public RNA-Seq databases, verified in collected clinical samples and mice pulmonary fibrosis model by Western blotting, qRT-PCR, ELISA and Immunohistochemical staining.

Critical-sized bone defects often lead to non-union and full-thickness defects of the calvarium specifically still present reconstructive challenges. In this study, we show that neurotrophic supplements induce robust in vitro expansion of mesenchymal stromal cells, and in situ transplantation of neurotrophic supplements-incorporated 3D-printed hydrogel grafts promote full-thickness regeneration of critical-sized bone defects. Single-cell RNA sequencing analysis reveals that a unique atlas of in situ stem/progenitor cells is generated during the calvarial bone healing in vivo.
