Abstract During the implantation process of cardiovascular implants, vascular damage caused by inflammation occurs, and inflammatory is accompanied oxidative stress. Currently, carbon monoxide (CO) has been demonstrated to exhibit various biological effects including vasodilatation, antithrombotic, anti-inflammatory, apoptosis-inducing antiproliferative properties. In this study, hemoglobin/epigallocatechin-3-gallate (EGCG) core-shell nanoparticle-containing coating on stainless steel was prepared for CO loading modulation. Inspired strong coordination ability with CO, hemoglobin nanoparticle first encapsulated into EGCG metal-phenolic networks. A polydopamine (PDA) linking layer then coated 316 steel, hemoglobin/EGCG nanoparticles were loaded subsequent PDA deposition. It showed that maximum release amount 17.0 nmol/cm2 in 48 h. vitro evaluations conducted a simulated environment revealed coating, which released from nanoparticles, effectively mitigated lipopolysaccharide-induced response macrophages. Specifically, it decreased expression tumor necrosis factor-α, increased interleukin-10, suppressed polarization macrophages toward M1 phenotype reduced intracellular reactive oxygen species (ROS). Furthermore, under stress conditions, apoptosis endothelial cells induced down-regulated ROS levels. vivo results further confirmed its capabilities, macrophage-mediated responses modulated

Abstract Infectious diseases pose considerable challenges to public health, particularly with the rise of multidrug‐resistant pathogens that globally cause high mortality rates. These can persist on surfaces and spread in healthcare settings. Advances have been made developing antimicrobial materials reduce transmission pathogens, including composed naturally sourced polyphenols their derivatives, which exhibit potency, broad‐spectrum activity, a lower likelihood promoting resistance. This review provides an overview recent advances fabrication phenolic biomaterials, where natural compounds act as active agents or encapsulate other (e.g., metal ions, peptides, biopolymers). Various forms biomaterials synthesized through these two strategies, particles, capsules, hydrogels, coatings, are summarized, focus application wound healing, bone repair regeneration, oral coatings for medical devices. The potential advanced promising therapeutic approach combating antimicrobial‐resistant infections reducing microbial transmission.

Copper plays critical roles as a metal active site cofactor and metalloallosteric signal for enzymes involved in cell proliferation metabolism, making it an attractive target cancer therapy. In this study, we investigated the efficacy of polydopamine nanoparticles (PDA NPs), classically applied removal from water, therapeutic strategy depleting intracellular labile copper pools triple-negative breast models through metal-chelating groups present on PDA surface. By using activity-based sensing probe FCP-1, could track PDA-induced depletion while leaving total levels unchanged link to selective MDA-MB-231 death. Further mechanistic investigations revealed that NPs increased reactive oxygen species (ROS) levels, potentially inactivation superoxide dismutase 1 (SOD1), copper-dependent antioxidant enzyme. Additionally, were found interact with mitochondrial membrane, resulting increase membrane potential, which may contribute enhanced ROS production. We employed vivo tumor model validate NPs. Remarkably, absence any additional treatment, presence alone led significant reduction volume by factor 1.66 after 22 days growth. Our findings highlight potential promising approach selectively targeting modulating inducing oxidative stress, leading growth inhibition shown these models.

Challenges in directed differentiation and survival limit the clinical use of stem cells despite their promising therapeutic potential regenerative medicine. Nanotechnology has emerged as a powerful tool to address these challenges enable precise control over cell fate. In particular, nanomaterials can mimic an extracellular matrix provide specific cues guide proliferation field nanotechnology. For instance, recent studies have demonstrated that nanostructured surfaces scaffolds enhance lineage commitment modulated by intracellular regulation external stimulation, such reactive oxygen species (ROS) scavenging, autophagy, or electrical stimulation. Furthermore, nanoframework-based upconversion nanoparticles be used deliver bioactive molecules, growth factors, genetic materials facilitate tissue regeneration. The increasing nanostructures research led development new approaches. Therefore, this review provides overview advances for modulating differentiation, including metal-, carbon-, peptide-based strategies. addition, we highlight nano-enabled technologies applications therapy focusing on improving efficiency therapeutics. We believe will inspire researchers intensify efforts deepen understanding, thereby accelerating modulation, pharmaceutical industry,

Diabetic foot ulcer is a common and serious complication of diabetes, with high risk amputation, recurrence, mortality. Aiming at the characteristics diabetic wounds based on result network pharmacology, tailored ligand cyanidin-3-O-glucoside (C3G) was selected to construct metal-phenolic (CM) through self-assembly reaction manganese ions. CM integrates pharmacological advantages C3G in antidiabetes anti-inflammatory activity networks by simulating metal coordination structure antioxidant enzymes. Reasonably, wound areas db/db mice treatment rapidly decreased 3.06% day 14, accompanied improvement tissue microenvironment. Mechanism investigation indicated that can not only reduce inflammation activation immunoreaction but also increase gene transcripts glucose metabolism, response hypoxia, angiogenesis. It believed this work opens way for designing disease-specific networks, biosafety promotes clinical wounds.

The overuse of antibiotics has increased the prevalence drug-resistant bacteria in periodontitis. "Sentinel" gingival fibroblasts, stimulated by pathogenic bacteria, continue to release signaling factors that affect stem cell repair and recruit immune cells, resulting persistent inflammation periodontal tissues, eventually leading loosening loss teeth. Periodontal cause surface hypoxia, fibroblasts inflammatory microenvironment express HIF-1α, promoting hypoxic areas pockets. No drug delivery system is available for region We synthesized BI NPs via berberine (BBR) indocyanine green (ICG) formed BIP wrapping with polydopamine (PDA), were delivered pocket hitchhiking anaerobic probiotic Bifidobacterium bifidum (Bif). released berberin under near-infrared (NIR) irradiation, which inhibited sulfur metabolism Porphyromonas gingivalis mild photothermal action BBR-targeted serine acetyltransferase, a decrease resistance oxidative stress, thus exerting nonantibiotic bacteriostatic effect. This effect facilitated uptake bygingival fibroblasts. Moreover, BBR targeted nuclear factor-erythroid 2-related factor 2 (NRF2) reduce ferroptosis, fibroblast supernatant modulated macrophage polarization through NF-κB pathway. In periodontitis rat model, Bif@BIP+NIR treatment carried deep pockets, decreasing local ferroptosis alleviating symptoms.
