Hydrophilicity-Driven Modulation of Amyloid-β(1-40) Fibrillation by Engineered Nanomaterials.

Amyloid-β (Aβ) fibrillation is a spontaneous, thermodynamic process governed by nucleation and elongation. While many studies have explored the ability of engineered nanomaterials (ENMs) to modulate Aβ fibrillation, such as inhibitors, promoters, and dual-modulators, the key physicochemical property of ENMs that determines this behavior remains unclear. In this study, we developed a comprehensive library of ENMs with well-controlled physicochemical properties, including surface charges, morphologies, and hydrophilicity, to systematically investigate their effects on Aβ40 fibrillation.

Alcohol-Mediated Abandoned Silk Textile Transformation to Self-Support Carbon Frameworks Anchoring with CoSe for Bifunctional Electrocatalytic Water Splitting.

Developing a self-supported structure with an enriched active site is crucial for enhancing the water splitting performance of transition metal selenide electrocatalysts. Herein, we present a cobalt selenide/waste silk-derived carbon (CoSe/SC) hybrid catalyst synthesized through a synergistic alcohol-mediated solvothermal and controlled pyrolysis strategy. Notably, the incorporation of ethanol transforms silk from a random coil to a highly crystalline β-sheet conformation, which effectively preserves the hierarchical architecture during carbonization.

Clinical and endoscopic characteristics of colorectal sessile serrated lesion with dysplasia: a single-center cross-sectional comparative study.

Background: The precancerous lesion of colorectal cancer (CRC), colorectal sessile serrated lesion (SSL), takes an average of 15 years to germinate from no cell dysplasia to CRC, and 2 years for SSL with dysplasia (SSL-D). To date, the impacts of endoscopic and pathological features of SSL and SSL-D on the development of dysplasia remain unclear. In this study, we explored these impacts, striving to provide reference for its classification, detection, and diagnosis.

Macrophage Membrane-Coated Liposomes Delivering Vonoprazan Disrupt Mitochondrial Oxidative Phosphorylation in Diffuse Large B-Cell Lymphoma.

Background: A significant proportion of patients fail to respond adequately to the standard R-CHOP regimen for diffuse large B-cell lymphoma (DLBCL). Rapid proliferation requires energy and the interaction between H ions and mitochondria suggests that regulating acid secretion in tumor cells may be a therapeutic strategy for DLBCL. This study constructed a macrophage membrane-coated liposomal formulation (MM-Lipid@Vpz) for the targeted delivery of vonoprazan to combat DLBCL, which enables the evasion of the reticuloendothelial system, ensuring enhanced specificity in tumor targeting.

Delayed diagnosis of the full triad autoimmune polyendocrine syndrome type 2 with adrenal crisis: a case report and literature review.

Background: Autoimmune polyendocrine syndrome type 2 (APS-2) is a rare disorder characterized by autoimmune damage to multiple endocrine glands and typically involves primary adrenal insufficiency (PAI), autoimmune thyroid disease (AITD), and type 1 diabetes mellitus (T1DM). Clinical presentations that feature the full triad alongside adrenal crisis (AC) are rare, with only four such cases reported globally. While AC is the most life-threatening acute complication of APS-2, its pathogenesis is complex and incompletely understood.

Tumor signal amplification and immune decoy strategy using bacterial membrane-coated nanoparticles for immunotherapy.

In cancer therapy, tumor cells can diminish their signals through mechanisms such as immune escape, thereby evading recognition and elimination by the immune system. Providing tumor signals to enhance the recognition of tumor sites is considered a crucial approach in cancer treatment. Inspired by the decoy-induced directed feeding of fish, we propose a biomimetic nanoparticle system for tumor signal amplification.

DRAM1 enhances the proliferation and metastasis of gastric cancer through the PI3K/AKT/mTOR signaling pathway and energy metabolism.

Effective treatment of advanced stages remains challenging, emphasizing the need for new therapeutic targets. Metabolic reprogramming, a hallmark of tumors, plays a pivotal role in tumor progression, immune evasion, and immune surveillance.

Stiff gel-protected fiber-shaped supercapacitors based on CNFA/silk composite fiber with superhigh interference-resistant ability as self-powered temperature sensor.

The development of self-powered sensors with interference-resistant detection is a priority area of research for the next generation of wearable electronic devices. Nevertheless, the presence of multiple stimuli in the actual environment will result in crosstalk with the sensor, thereby hindering the ability to obtain an accurate response to a singular stimulus. Here, we present a self-powered sensor composed of silk-based conductive composite fibers (CNFA@ESF), which is capable of energy storage and sensing.

However, the role of MSU crystal physicochemical properties in inducing cell death in neutrophil and macrophage is still unclear. In this study, MSU crystals of different sizes are synthesized to explore the role of pyroptosis in gout.

Highly efficient dissolution and reinforcement mechanism of robust and transparent cellulose films for smart packaging.

The packaging of fresh foods increasingly focuses on renewable and eco-friendly cellulose films, but their low dissolution efficiency and weak mechanical strength greatly limit their wide application, which also cannot be used for smart packaging. Here, a highly efficient synergistic chloride-salt dissolution method was proposed to fabricate robust, transparent, and smart cellulose films. Cellulose films with appropriate Ca concentration exhibited robust mechanical strength, better thermal stability, high transparency and crystallinity.

Thermo-sensitive composite microspheres incorporating cellulose nanocrystals for regulated drug release kinetics.

Thermo-sensitive composite microspheres (TPCP) were developed to achieve the on-demand release of drugs. The TPCP microspheres were synthesized using Oil-in-Water (O/W) emulsion evaporation technique and then impregnated with thermo-sensitive polyethylene glycol (PEG). The addition of cellulose nanocrystals (CNCs) significantly enhance thermal stability, crystallization ability, and surface hydrophilicity of TPCP microspheres due to heterogeneous nucleation effect and hydrogen bonding interaction, resulting in stable microsphere structure.

Monosodium urate crystals with controlled shape and aspect ratio for elucidating the pathological progress of acute gout.

Gout is a self-limiting inflammatory arthritis mediated by the precipitation of monosodium urate (MSU) crystals that further activate the NLRP3 inflammasome and initiate a cascade of inflammatory events. However, the key physicochemical properties of MSU crystals that determine the acute phase of gout have not been fully identified. In this study, a library of engineered MSU crystals with well-controlled size and shape is designed to explore their proinflammatory potentials in mediating the pathological progress of gout.

Validation of the mechano-bactericidal mechanism of nanostructured surfaces with finite element simulation.

The mechano-bactericidal property of nanostructured surfaces has become the focus of intensive research toward the development of a new generation of antibacterial surfaces, especially in the current era of spreading antibiotic resistance. However, the mechanisms underlying nanostructured surfaces mechanically damaging bacteria remain unclear, which ultimately limits translational potential toward real-world applications. Using finite element simulation technique, we developed the three-dimensional thin wall with turgor pressure finite element model (3D-TWTP-FEM) of bacterial cell and verified the reliability of this model by the AFM indentation experiment simulation of the cell, and the cell model is able to simulate suspended bacterial cell and the process of cell adhering to the flat and nanopillar surfaces.
