Reactive Oxygen Species-Responsive Gel-Based Microneedle Patches with Antimicrobial and Immunomodulating Properties for Oral Mucosa Disease Treatment.

Oral ulcer wounds are difficult to heal due to bacterial infections, persistent inflammatory responses, and excessive reactive oxygen species (ROS). Therefore, the elimination of bacteria, removal of ROS, and reduction of inflammation are prerequisites for the treatment of mouth ulcer wounds. In this study, oligomeric proanthocyanidins (OPC) and 3-(aminomethyl)phenylboronic acid-modified hyaluronic acid (HP) were used to form polymer gels through dynamic covalent borate bonds.

Structural insights into glucose-6-phosphate recognition and hydrolysis by human G6PC1.

The glucose-6-phosphatase (G6Pase) is an integral membrane protein that catalyzes the hydrolysis of glucose-6-phosphate (G6P) in the endoplasmic reticulum lumen and plays a vital role in glucose homeostasis. Dysregulation or genetic mutations of G6Pase are associated with diabetes and glycogen storage disease 1a (GSD-1a). Studies have characterized the biophysical and biochemical properties of G6Pase; however, the structure and substrate recognition mechanism of G6Pase remain unclear.

Intrinsic Mechanical Effects on the Activation of Carbon Catalysts.

The mechanical effects on carbon-based metal-free catalysts (C-MFCs) have rarely been explored, despite the global interest in C-MFCs as substitutes for noble metal catalysts. Stress is ubiquitous, whereas its dedicated study is severely restricted due to its frequent entanglement with other structural variables, such as dopants, defects, and interfaces in catalysis. Herein, we report a proof-of-concept study by establishing a platform to continuously apply strain to a highly oriented pyrolytic graphite (HOPG) lamina, simultaneously collecting electrochemical signals.

gene mutation through CRISPR RNA-guided base editing weakens bacterial virulence and immune evasion.

Numerical investigation of coal pillar damage mechanisms for various width-to-height ratios.

Pillar stability has garnered significant attention owing to the effects of pillars on coal resource recovery rate, coal pillar stability, and coal bump risk. This study examined the roadway stability control principles of conventional and yield coal pillars. The conventional coal pillars were designed as load-bearing structures with a high load-bearing capacity to carry most of the abutment load, while yield coal pillars were designed as buffer structures for transferring rapidly increasing abutment loads to adjacent solid coal ribs by progressive deformation.

DISCOntinuation of disease-modifying therapies in MS: The DISCOMS extension trial.

Background: In the DISCOMS (DISCOntinuation of disease-modifying therapies (DMTs) in multiple sclerosis (MS)) randomized clinical trial, we could not demonstrate that discontinuing MS DMTs in older, stable adults was not inferior to continuing DMTs. Relapses were rare in both groups, and most new disease activity was one to two new brain magnetic resonance imaging (MRI) lesions unassociated with clinical changes.

Objective/aims: Describe results of the DISCOMS extension study.

Polystyrene microplastics induce liver fibrosis and lipid deposition in mice through three hub genes revealed by the RNA-seq.

Nano- and microplastics (NMPs) have become a serious global environmental threat that causes damage to mammalian organs. In this work, we investigated the potential molecular mechanism underlying the development of liver fibrosis induced by long-term exposure to three different sized polystyrene (PS)-NMPs (80 nm, 0.5 µm and 5 µm) in mice.

Trust in scientists and their role in society across 68 countries.

Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of the best available evidence, especially during crises. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists.

Perceptions of science, science communication, and climate change attitudes in 68 countries - the TISP dataset.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Construction of enzyme-MOFs composite with carbon dots: A strategy to enhance the activity and increase the growth rate of the enzyme-ZIF-8 composite.

Encapsulating enzymes in metal-organic frameworks (MOFs) enhances enzyme protection and improves the accuracy of inhibitor recognition and screening. Zeolitic imidazolate framework-8 (ZIF-8) has been widely used as a host matrix for enzyme immobilization. However, challenges such as the microporous structure and hydrophobicity of ZIF-8, along with the protonation of 2-methylimidazole, hinder the maintenance of activity and the rapid formation of composite.

E3 ubiquitin ligase CHIP facilitates cAMP and cGMP signalling cross-talk by polyubiquitinating PDE9A.

The carboxyl terminus of Hsc70-interacting protein (CHIP) is pivotal for managing misfolded and aggregated proteins via chaperone networks and degradation pathways. In a preclinical rodent model of CHIP-related ataxia, we observed that CHIP mutations lead to increased levels of phosphodiesterase 9A (PDE9A), whose role in this context remains poorly understood. Here, we investigated the molecular mechanisms underlying the role of PDE9A in CHIP-related ataxia and demonstrated that CHIP binds to PDE9A, facilitating its polyubiquitination and autophagic degradation.
