The effect of spherical projection on spin tests for brain maps.

Statistical comparison between brain maps is a standard procedure in neuroimaging. Numerous inferential methods have been developed to account for the effect of spatial autocorrelation when evaluating map-to-map similarity. A popular method to generate surrogate maps with preserved spatial autocorrelation is the spin test.

Episode-specific cortical functional connectome reorganization and neurobiological correlates in bipolar disorder: a cross-sectional study.

Background: Bipolar disorder (BD) is a heterogeneous psychiatric condition characterized by distinct episodes: manic (BipM), depressive (BipD), mixed (mBD), and remission (rBD). Current evidence indicates alterations in brain functional connectivity in BD, yet a comprehensive understanding across all episodes remains incomplete.

Methods: Here, to investigate how different BD episodes alter brain functional organization, we calculated the sensory-association axis using diffusion map embedding on the functional connectome matrix and compared this axis between the four BD groups and neurotypical controls.

Glycosaminoglycans in hard tissue repair and regeneration: A group of re-emerging natural carbohydrates.

Bone, cartilage, and tooth, can develop hard tissue-related diseases due to tumors, inflammation, and aging. Within the realm of hard tissue engineering, scaffolds play crucial roles in mimicking the properties of natural extracellular matrix (ECM) while meeting strict requirements for mechanical and biological characteristics. As key components of the ECM, the applications of glycosaminoglycans (GAGs) in hard tissue regeneration remained limited due to their inherently weak mechanical properties and stability.

Mapping cerebral blood perfusion and its links to multi-scale brain organization across the human lifespan.

Blood perfusion delivers oxygen and nutrients to all cells, making it a fundamental feature of brain organization. How cerebral blood perfusion maps onto micro-, meso- and macro-scale brain structure and function is therefore a key question in neuroscience. Here we analyze pseudo-continuous arterial spin labeling (ASL) data from 1305 healthy individuals in the HCP Lifespan studies (5-22 and 36-100 years) to reconstruct a high-resolution normative cerebral blood perfusion map.

Multivariate Resting-State Functional Connectivity Features Linked to Transdiagnostic Psychopathology in Early Psychosis.

Background: Early psychosis (EP) is characterized by neurobiological changes, including alterations in resting-state functional connectivity (RSFC). We now understand that symptoms and neural changes may overlap across EP diagnostic categories. However, the relationship between RSFC patterns and transdiagnostic symptom dimensions remains poorly understood.

Dose-Dependent Effects of Remimazolam on Early Perioperative Neurocognitive Disorders in Elderly Colorectal Cancer Patients Undergoing Laparoscopic Surgery.

Objective: To study the effect of different doses of remimazolam on the maintenance of anesthesia and its impact on postoperative cognitive function in elderly patients undergoing laparoscopic colorectal surgery.

Methods: A total of 120 elderly patients scheduled for laparoscopic colorectal surgery under general anesthesia (both sexes included, ASA grade (II-III) were randomly assigned to experimental groups (R1-R3) and control group (P), with 30 cases per group. The experimental groups received different remimazolam maintenance doses: R1 (0.

Incretin Receptor Agonism, Fat-free Mass, and Cardiorespiratory Fitness: A Narrative Review.

Context: Individuals with obesity often exhibit low muscle quality and are at risk of reduced muscle mass and diminished cardiorespiratory fitness (CRF). Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RA) and dual GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptor agonist (GLP-1/GIPRA) promote significant loss in adipose tissue but are also associated with notable reductions in fat-free mass (FFM). It is not yet understood how these drugs affect CRF which is an independent predictor of all-cause and cardiovascular mortality.

Benchmarking methods for mapping functional connectivity in the brain.

The networked architecture of the brain promotes synchrony among neuronal populations. These communication patterns can be mapped using functional imaging, yielding functional connectivity (FC) networks. While most studies use Pearson's correlations by default, numerous pairwise interaction statistics exist in the scientific literature.

Fully automated insulin delivery systems in type 1 diabetes: A systematic review and meta-analysis.

Aims: The landscape of insulin delivery is evolving, transitioning from hybrid automated insulin delivery (AID) to more sophisticated fully AID systems. We aimed to compare the efficacy of fully AID systems with any insulin delivery method in type 1 diabetes (T1D).

Materials And Methods: Following registration in PROSPERO, CRD42024528669, PubMed, Embase, Cochrane Library and Web of Science were searched up to 26 February 2025 for randomised clinical trials comparing fully AID systems to any insulin delivery method in T1D.

Metabolic and vascular insulin resistance: partners in the pathogenesis of cardiovascular disease in diabetes.

Vascular insulin resistance has emerged as a pivotal factor in the genesis of cardiovascular disease (CVD) in people with diabetes. It forms a complex pathogenic partnership with metabolic insulin resistance to significantly amplify the CVD risk of diabetes and other affected populations. Metabolic insulin resistance (characterized by quantitatively diminished insulin action on glucose metabolism in skeletal muscle, liver, and adipose tissue) is a hallmark of diabetes, obesity, and related conditions.

The interrelationship among exercise intensity, endothelial function, and ghrelin in healthy humans.

Ghrelin circulates in acylated (AG) and deacylated (DAG) isoforms and both may impact endothelial function (EF). Although acute exercise has been shown to modulate ghrelin levels and EF, data on the impact of exercise intensity on these parameters are scarce. To investigate the effect of exercise intensity and sex on EF and ghrelin levels, nine males (age: 43.

Comprehensive profiling of anaesthetised brain dynamics across phylogeny.

The intrinsic dynamics of neuronal circuits shape information processing and cognitive function. Combining non-invasive neuroimaging with anaesthetic-induced suppression of information processing provides a unique opportunity to understand how local dynamics mediate the link between neurobiology and the organism's functional repertoire. To address this question, we compile a unique dataset of multi-scale neural activity during wakefulness and anesthesia encompassing human, macaque, marmoset, mouse and nematode.

Bilirubin Targeting WNK1 to Alleviate NLRP3-Mediated Neuroinflammation.

Bilirubin, an endogenous metabolite with many significant physiological roles, particularly anti-inflammatory properties, shows great promise as a treatment for inflammatory diseases. However, the binding targets and downstream signaling mechanisms of bilirubin remain unclear. Here, by using quantitative phosphorylation proteomics and several powerful chemical biology techniques such as the Cellular Thermal Shift Assay (CETSA), molecular docking, and MicroScale Thermophoresis (MST), it is identified and confirmed that with-no-lysine (K) kinase 1 (WNK1) is the primary target of bilirubin at physiological concentrations.

Exercise Intolerance in Type 2 Diabetes: A Systematic Review and Meta-Analysis.

Background: To analyze the effect of type 2 diabetes (T2D) on cardiorespiratory fitness.

Methods: A multilevel model using restricted maximum likelihood method was used to analyze pooled data. Inclusion criteria included adults aged >18 years, one group of individuals needed to have been diagnosed with T2D, the control group must not have had insulin resistance, the study must report peak oxygen uptake, there was no exercise training before tests of functional capacity, and subjects may not have had overt cardiovascular disease, cancer, transplant surgery, or bariatric surgery.

Benchmarking macaque brain gene expression for horizontal and vertical translation.

The spatial patterning of gene expression shapes cortical organization and function. The macaque is a fundamental model organism in neuroscience, but the translational potential of macaque gene expression rests on the assumption that it is a good proxy for patterns of corresponding proteins (vertical translation) and for patterns of orthologous human genes (horizontal translation). Here, we systematically benchmark regional gene expression in macaque cortex against (i) macaque cortical receptor density and in vivo and ex vivo microstructure and (ii) human cortical gene expression.

Careful attention to the eco-toxicity and secondary water pollution of the degradation by-products.

Most of studies have mainly paid attention to the removal efficiency of a water treatment technology, while often overlooking the environmental and ecological toxicity. However, are water treatment technologies really environmental-/eco-friendly? If the as-generated chemicals are more toxic, it may lead to more severe secondary pollution. In this work, two novel integrated systems of Vis/CuO/HO (visible light-excited HO activation) and Vis/CuO/PS (visible light-excited persulfate (PS, NaSO activation) were designed and investigated fully, in which rhodamine B (RhB) was selected as the representative organic wastewater pollutant to assure the technology feasibility, although it has been studied widely.

Waist-to-hip ratio better reflect beta-cell function and predicts diabetes risk in adult with overweight or obesity.

Objective: Controversy remains as to which obesity measures better predict type 2 diabetes (T2D) risk in overweight or obese individuals. The objective of this study is to determine which commonly used obesity measures better reflect beta cell function and predict T2D risk in participants with overweight or obesity and to validate the findings using prospective cohort data.

Patients And Methods: Cross-sectional data from the Obesity Clinic of the Xiangya Hospital of the Central South University and prospective cohort from UK Biobank.

Interplay of fatty acids, insulin and exercise in vascular health.

Fatty acid metabolism, exercise, and insulin action play critical roles in maintaining vascular health, especially relevant in metabolic disorders such as obesity, type 2 diabetes, and cardiovascular disease. Insulin, a vasoactive hormone, induces arterial vasodilation throughout the arterial tree, increasing arterial compliance and enhancing tissue perfusion. These effects, however, are impaired in individuals with obesity and type 2 diabetes, and evidence suggests that vascular insulin resistance contributes to the pathogenesis of type 2 diabetes and its cardiovascular complications.

Efficacy and Safety of Automated Insulin Delivery Systems in Patients with Type 1 Diabetes Mellitus: A Systematic Review and Meta-Analysis.

Backgruound: Automated insulin delivery (AID) systems studies are upsurging, half of which were published in the last 5 years. We aimed to evaluate the efficacy and safety of AID systems in patients with type 1 diabetes mellitus (T1DM).

Methods: We searched PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.

The Impact of Exercise Intensity and Sex on Endogenous Ghrelin Levels and Appetite in Healthy Humans.

Context: Ghrelin circulates in acylated (AG) and deacylated (DAG) forms, which are known to affect appetite. Although acute exercise has been shown to modulate ghrelin levels, data on the impact of exercise intensity on AG and DAG levels and their effects on appetite are sparse and primarily limited to males.

Objective: To investigate the effect of exercise intensity and sex on ghrelin levels and appetite in untrained humans.

Selective Vulnerability of GABAergic Inhibitory Interneurons to Bilirubin Neurotoxicity in the Neonatal Brain.

Hyperbilirubinemia (HB) is a key risk factor for hearing loss in neonates, particularly premature infants. Here, we report that bilirubin (BIL)-dependent cell death in the auditory brainstem of neonatal mice of both sexes is significantly attenuated by ZD7288, a blocker for hyperpolarization-activated cyclic nucleotide-gated (HCN) channel-mediated current ( ), or by genetic deletion of HCN1. GABAergic inhibitory interneurons predominantly express HCN1, on which BIL selectively acts to increase their intrinsic excitability and mortality by enhancing HCN1 activity and Ca-dependent membrane targeting.

Room-temperature ferroelectric, piezoelectric and resistive switching behaviors of single-element Te nanowires.

Ferroelectrics are essential in memory devices for multi-bit storage and high-density integration. Ferroelectricity mainly exists in compounds but rare in single-element materials due to their lack of spontaneous polarization in the latter. However, we report a room-temperature ferroelectricity in quasi-one-dimensional Te nanowires.

A Nanozyme-Boosted MOF-CRISPR Platform for Treatment of Alzheimer's Disease.

Rectifying the aberrant microenvironment of a disease through maintenance of redox homeostasis has emerged as a promising perspective with significant therapeutic potential for Alzheimer's disease (AD). Herein, we design and construct a novel nanozyme-boosted MOF-CRISPR platform (CMOPKP), which can maintain redox homeostasis and rescue the impaired microenvironment of AD. By modifying the targeted peptides KLVFFAED, CMOPKP can traverse the blood-brain barrier and deliver the CRISPR activation system for precise activation of the Nrf2 signaling pathway and downstream redox proteins in regions characterized by oxidative stress, thereby reinstating neuronal antioxidant capacity and preserving redox homeostasis.
