Co-methylation networks associated with cognition and structural brain development during adolescence.

Introduction: Typical adolescent neurodevelopment is marked by decreases in grey matter (GM) volume, increases in myelination, measured by fractional anisotropy (FA), and improvement in cognitive performance.

Methods: To understand how epigenetic changes, methylation (DNAm) in particular, may be involved during this phase of development, we studied cognitive assessments, DNAm from saliva, and neuroimaging data from a longitudinal cohort of normally developing adolescents, aged nine to fourteen. We extracted networks of methylation with patterns of correlated change using a weighted gene correlation network analysis (WCGNA).

Alternations of interhemispheric functional connectivity in patients with acute acquired concomitant esotropia: a resting state fMRI study using voxel-mirrored homotopic connectivity.

Purpose: To investigate the changes in cerebral hemispheric functional connections in patients with acute acquired concomitant esotropia (AACE) and their relationship with clinical manifestations, utilizing voxel-mirrored homotopic connectivity (VMHC).

Methods: A prospective, observational study was conducted involving 32 AACE patients and 31 age-, sex-, and education-matched healthy controls (HC). The resting-state functional magnetic resonance imaging (rs-fMRI) signals, binocular vision function, and psychometric scale scores were collected rs-fMRI data and structural image data were analyzed for VMHC, and a two-sample -test was used to analyze the differences in VMHC between groups.

Aspirin-based PROTACs as COX-2 degraders for anti-inflammation.

Cyclooxygenase-2 (COX-2) is a key enzyme in the biosynthesis of prostaglandins and plays a special role in the process of inflammatory response. COX-2 is a target of non-steroidal anti-inflammatory drugs (NSAIDs), which can effectively relieve inflammation, pain and fever responses by inhibiting COX-2. Despite the significant study progress of inhibitors targeting COX-2, the development of COX-2 degraders remains insufficient.

Hijacking the hyaluronan assisted iron endocytosis to promote the ferroptosis in anticancer photodynamic therapy.

Photodynamic therapy (PDT) eradicates tumor cells by the light-stimulated reactive oxygen species, which also induces lipid peroxidation (LPO) and subsequently ferroptosis, an iron-depended cell death. Ferroptosis has a tremendous therapeutic potential in cancer treatment, however, the ferroptosis efficiency is largely limited by the available iron in cells. Through hijacking the CD44-mediated iron endocytosis of hyaluronan (HA), here PDT with enhanced ferroptosis was realized by a HA@Ce6 nanogel self-assembled from HA, a photosensitizer Chlorin e6 (Ce6) and Fe as cross-linkers.

Based on apatite textures and geochemistry characteristics, the apatites were categorized into two distinct groups.

Brain networks and intelligence: A graph neural network based approach to resting state fMRI data.

Resting-state functional magnetic resonance imaging (rsfMRI) is a powerful tool for investigating the relationship between brain function and cognitive processes as it allows for the functional organization of the brain to be captured without relying on a specific task or stimuli. In this paper, we present a novel modeling architecture called BrainRGIN for predicting intelligence (fluid, crystallized and total intelligence) using graph neural networks on rsfMRI derived static functional network connectivity matrices. Extending from the existing graph convolution networks, our approach incorporates a clustering-based embedding and graph isomorphism network in the graph convolutional layer to reflect the nature of the brain sub-network organization and efficient network expression, in combination with TopK pooling and attention-based readout functions.

Networks extracted from nonlinear fMRI connectivity exhibit unique spatial variation and enhanced sensitivity to differences between individuals with schizophrenia and controls.

Schizophrenia is a chronic brain disorder associated with widespread alterations in functional brain connectivity. Although data-driven approaches such as independent component analysis are often used to study how schizophrenia impacts linearly connected networks, alterations within the underlying nonlinear functional connectivity structure remain largely unknown. Here we report the analysis of networks from explicitly nonlinear functional magnetic resonance imaging connectivity in a case-control dataset.

Visualization of Protein-Protein Interaction In Situ Using Hybridization-Enhanced Proximity Ligation Assay.

Adolescent brain maturation associated with environmental factors: a multivariate analysis.

Human adolescence marks a crucial phase of extensive brain development, highly susceptible to environmental influences. Employing brain age estimation to assess individual brain aging, we categorized individuals ( = 7,435, aged 9-10 years old) from the Adolescent Brain and Cognitive Development (ABCD) cohort into groups exhibiting either accelerated or delayed brain maturation, where the accelerated group also displayed increased cognitive performance compared to their delayed counterparts. A 4-way multi-set canonical correlation analysis integrating three modalities of brain metrics (gray matter density, brain morphological measures, and functional network connectivity) with nine environmental factors unveiled a significant 4-way canonical correlation between linked patterns of neural features, air pollution, area crime, and population density.

Associative Learning-Induced Synaptic Potentiation at the Two Major Hippocampal CA1 Inputs for Cued Memory Acquisition.

Learning-associated functional plasticity at hippocampal synapses remains largely unexplored. Here, in a single session of reward-based trace conditioning, we examine learning-induced synaptic plasticity in the dorsal CA1 hippocampus (dCA1). Local field-potential recording combined with selective optogenetic inhibition first revealed an increase of dCA1 synaptic responses to the conditioned stimulus (CS) induced during conditioning at both Schaffer collaterals to the stratum radiatum (Rad) and temporoammonic input to the lacunosum moleculare (LMol).

Citrus rhoifolin alleviated DSS-induced acute colitis by activating CEMIP/SLC7A11-mediated cystine uptake and inhibiting epithelial ferroptosis.

Purpose: Pharmacological inhibition of ferroptosis, a specific form of regulated cell death, has emerged as a promising therapeutic strategy for alleviating symptoms and enhancing endoscopic outcomes in patients suffering from ulcerative colitis. Rhoifolin, a prominent bioactive constituent abundant in the widely consumed fruit Citrus grandis (grapefruit), has garnered attention for its ability to diminish the levels of reactive oxygen species (ROS), which are key inducers of ferroptosis across diverse cellular contexts. In this study, we aimed to investigate whether rhoifolin exerts its beneficial effects on colitis by modulating the process of epithelial ferroptosis.

IGFALS suppresses hepatocellular carcinoma progression by stabilizing PPAR-γ.

IGFALS forms stable ternary complexes with insulin-like growth factors (IGF1 and IGF2) and IGF-binding proteins (IGFBP3 and IGFBP5), which prolong the half-lives of IGFs. Through immunohistochemical analysis of 90 pairs of clinical samples and bioinformatics analysis, we observed downregulation of IGFALS in hepatocellular carcinoma tissues, which was associated with poor patient prognosis. This prompted us to explore the specific molecular mechanism of action of IGFALS in the inhibition of hepatocellular carcinoma (HCC), which could be a potential new target for the treatment of HCC.

The effect of polyvinyl chloride microplastics on soil properties, greenhouse gas emission, and element cycling-related genes: Roles of soil bacterial communities and correlation analysis.

Different shapes (membranes and particles) and concentrations (1 % (w/w) and 2 % (w/w)) of polyvinyl chloride (PVC) microplastics (MPs) were investigated to determine their impact on the soil environment. The incorporation of MPs can disrupt soil macroaggregates. Compared with 1 % (w/w) MPs, 2 % MPs resulted in a significant increase in soil organic carbon content.

The variation of resistome, mobilome and pathogen in domestic and industrial wastewater treatment systems.

Wastewater treatment plants (WWTPs), including both domestic and industrial facilities, are key contributors to antibiotic resistance genes (ARGs) and human pathogens in the environment. However, the characteristics and dissemination mechanisms of ARGs in domestic (SD) and industrial (SI) wastewater treatment systems remain unclear, leading to uncertainties in risk assessment. Based on metagenomic analysis, we observed significant differences in the compositions of resistome (ARGs and metal resistance genes, MRGs), mobilome (mobile genetic elements, MGEs), and bacterial community between SD and SI.

Numerical Analysis in Double-Sided Polishing: Mechanism Exploration of Edge Roll-Off.

Understanding the mechanism of stress concentration effects on the surface of semiconductor substrate materials-silicon wafers-in Double-Sided Polishing (DSP) is particularly important for improving polishing quality. In this study, a two-dimensional finite element model is established to study the effect of contact state and stress concentration during polishing on edge roll-off (ERO) and polishing rate uniformity. The variation in this contact state is influenced by changes in wafer thickness and the gap between it and the carrier.
