On the basis of satisfying the performance of antimicrobial conductive, hydrogels also need to improve the mechanical properties to adapt to more wearable device applications. In this study, glycerol and agar were introduced on the basis of nanosilver/nanocellulose composite antimicrobial strain-responsive hydrogels (AP hydrogels), and nanosilver/nanocellulose composite antimicrobial strain-responsive dual-network hydrogel (APA-DN hydrogel) could be constructed by a two-step moulding method of thermal initiation and sol-gelation, and encapsulated into a strain-responsive sensor. Tensile fracture strain and stress of the APA-DN hydrogel could reach that concomitant with an elongation of 2182.0 mm. The tensile fracture strain and stress of the APA-DN hydrogel can reach 2182.71% and 279.76 kPa, and the modulus of elasticity and toughness can reach 36.35 kPa and 2772.98 kJ/m3, thereby realising enhanced mechanical properties on the basis of the AP hydrogel. The relative resistance of the APA-DN hydrogel sensors was stable in the range of 0-120% under 100% strain cycling, maintaining stable repeatability and durability of strain response. The APA-DN hydrogels are capable of outputting stable and reproducible electrical signals in the monitoring of hand and head movements, and they are expected to be applied in human behaviour detection by collecting and classifying the response signals in the future.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"8853282251340167"},"PeriodicalIF":2.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144150561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trabecular titanium-aluminum-vanadium (Ti6Al4V) and hydroxyapatite (HA)-coated vacuum-plasma-sprayed (VPS) titanium with varying porosities and HA-coating thicknesses, have been developed to enhance fixation, though bone cellular response remains largely unknown. This study evaluated osteoblast responses to trabecular Ti6Al4V and three VPS titanium surfaces with 20%-40% or 30%-70% porosity and HA coatings of 60, 80, or 90 µm. Human primary osteoblasts were seeded and cultured for 29 days, to assess seeding efficiency, viability, metabolic activity, alkaline phosphatase activity, and the effect of osteoblast-released factors in conditioned medium during the last 4 days of culture on osteoclast formation. VPS-HA groups were first compared individually; when no differences were found, data were pooled for comparison with the trabecular group. Osteoblast seeding efficiency, viability, metabolic activity, and alkaline phosphatase activity were similar between VPS-HA surfaces. Moreover, osteoblast-conditioned medium did not affect osteoclast formation. Osteoblast seeding efficiency and viability were similar between the pooled VPS-HA and trabecular surface. Compared to the pooled VPS-HA, the trabecular surface increased osteoblast metabolic (1.5-2.7-fold) and alkaline phosphatase activity (6.5-15.2-fold). Osteoblast-conditioned medium reduced osteoclast formation (2.1-3.4-fold) on trabecular compared to the pooled VPS-HA surface. In conclusion, these findings show that VPS-HA surfaces with various porosities and HA-coating thicknesses similarly affect osteoblast and osteoclast responses, while trabecular surfaces enhance osteoblast responsiveness and inhibit osteoclast formation. These results might help to further improve early stability and reduce long-term loosening risk in uncemented knee replacements.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"8853282251346324"},"PeriodicalIF":2.3,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144142653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silk fibroin (SF) from Bombyx mori is commonly used for such grafts. In our previous study, we found that silk vascular grafts coated with sponge-like transgenic (TG) silk incorporating the arginine-glutamic acid-aspartate-valine (REDV) peptide and transplanted into rats yielded favorable results. In this study, we aimed to achieve even better results by incorporating additional peptides into TG silk containing REDV and coating silk vascular grafts with this sponge. Initially, we sought to identify such peptides. We attempted to immobilize several peptides containing REDV onto silk using cyanuric chloride. Cell culture experiments with normal human umbilical vein endothelial cells (HUVECs) were performed on SF, SF+REDV, SF + arginine-glycine- aspartate (RGD), SF+cysteine-alanine-glycine (CAG), and SF + isoleucine-lysine- valine- alanine-valine (IKVAV) films to assess adhesion, proliferation, and extensibility; SF+RGD and SF+IKVAV films demonstrated high adhesion behavior of HUVECs. In addition, platelet adhesion on these SF+peptide films was evaluated. Platelet adhesion strength was much higher on SF+RGD films than on other SF+peptide films. These results suggest that IKVAV may be the most suitable peptide for coating SF vascular grafts. Subsequently, we successfully produced TG silk incorporating IKVAV+REDV. We then coated small-diameter silk vascular grafts with sponge-like TG silk incorporating IKVAV+REDV and measured its physical properties.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"8853282251345003"},"PeriodicalIF":2.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144110933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neural tissue engineering provides a promising solution by creating supportive environments for nerve regeneration. This study used advanced 3D bioprinting to produce biomimetic scaffolds from graphene-enhanced bio-inks, integrating cells, scaffold materials, and growth signals. Compared to traditional methods, 3D printing ensures precise material distribution, improving cell density. The bio-ink, made of graphene (Gr), gelatin (Gel), and sodium alginate (SA), was tested at concentrations of 0.02%, 0.08%, and 0.2% to find the best formula for neural repair. Among four scaffold groups (Gel/SA, 0.02% Gr/Gel/SA, 0.08% Gr/Gel/SA, 0.2% Gr/Gel/SA), the 0.08% Gr scaffold showed the best mechanical strength, structural integrity, and biocompatibility. Graphene improved the scaffolds' compressive strength and degradation balance but reduced water absorption, porosity and increased the contact angle at higher concentrations. PC12 cells on the scaffolds showed excellent proliferation and minimal toxicity at lower graphene levels. The 0.08% Gr scaffold was most effective in nerve regeneration, highlighting the potential of graphene-enhanced 3D-printed scaffolds for neural tissue engineering.

The imine linkage in Try-CA and acid-dependent protonation of Try and fisetin endow the nanodrugs with pH-triggered dynamic changes of particle sizes, surficial charges, and drug release. Moreover, the combined use of Try-CA and fisetin also endows the nanodrugs with superior antioxidative, anti-inflammatory and antibacterial capabilities compared to their individual use. These characteristics of the nanodrugs facilitate long-term circulation stability, effective penetration through BBB, selective accumulation in the brain, and target to central and peripheral focal areas, thereby achieving comprehensive treatment or relief of SAE. Thus, these attractive experimental results illuminate the enormous potential of such pH-triggered small molecule nanodrugs for targeted SAE therapy, advancing their use in clinics.","PeriodicalId":15138,"journal":{"name":"Journal of Biomaterials Applications","volume":" ","pages":"1165-1176"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143079191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We successfully developed a peptides-functionalized gold nanoconstruct (P-AuNS) consisted of PD-L1-binding peptide (PD-L1pep, P) and gold nanostar (AuNS), which could bind to cell-surface PD-L1 specifically and deliver PD-L1 into PCa cells with high efficiency. In PCa cells, P-AuNS can efficiently degrade PD-L1 in a lysosomal-dependent manner. In the co-culture system of Jurkat cells and DU145 cells, P-AuNS restored the proliferative capacity and interferon-gamma (IFN-γ) secretion level of Jurkat cells inhibited by co-cultured DU145 cells, indicating that P-AuNS effectively hampered the interaction between PD-1 and PD-L1. In addition, in PCa-bearing mice, P-AuNS can effectively inhibit tumor growth and down-regulate PD-L1 protein levels, and in vivo experimental results show that P-AuNS has no systemic toxicity. P-AuNS block the interaction between PD-1 and PD-L1 by efficiently degrading PD-L1, thus restoring the antitumor activity of T cells and inhibiting tumor progression of PCa.

Additionally, AHPRzyme exhibits multiple anti-tumor mechanisms: ① The prussian blue nanozymes in AHPRzyme have catalase (CAT) activity, which decomposes H2O2 in human nasopharyngeal carcinoma CEN2 cells into non-toxic H2O, reducing H2O2 levels and minimizing damage to normal cells. The released O2 helps alleviate the hypoxic environment of the tumor, inhibiting lactate production due to hypoxia and consequently suppressing tumor growth. ② The prussian blue nanozymes also have peroxidase (POD) activity, which catalyzes H2O2 in tumor cells to generate ·OH, a reactive oxygen species, leading to tumor cell apoptosis. ③ The α-lipoic acid structure in AHPRzyme contains disulfide bonds that react with GSH, depleting excess glutathione (GSH) in tumor cells, disrupting the oxidative stress balance within the cells, and making them more sensitive to reactive oxygen species, thereby increasing tumor cell apoptosis.

The hydrogel, as a biomaterial, exhibits superior biocompatibility compared to other biomaterials such as bioceramics and bio-metal materials. It also demonstrates mechanical properties closer to those of natural intervertebral discs (IVDs) and favorable biodegradability conducive to IVD regeneration. Therefore, it has emerged as a promising candidate material in the field of regenerative medicine and tissue engineering for treating IDD. Hydrogels have made significant strides in the field of IDD treatment. Particularly, injectable hydrogels not only provide mechanical support but also enable controlled release of bioactive molecules, playing a crucial role in mitigating inflammation and promoting extracellular matrix (ECM) regeneration. Furthermore, the ability of injectable hydrogels to achieve minimally invasive implantation helps minimize tissue damage. This article initially provides a concise exposition of the structure and function of IVD, the progression of IDD, and delineates extant clinical interventions for IDD.
