Research progress on the synthesis, performance regulation, and applications of Prussian blue nanozymes.

Nanocatalytic medicine offers a novel solution to address the issues of low efficacy, potential side effects, and the development of drug resistance associated with traditional therapies. Therefore, developing highly efficient and durable nanozymes is of great significance for treating diseases related to oxidative stress. In recent years, prussian blue nanoparticles (PBNPs) have been demonstrated to possess multiple enzyme-like catalytic activities and are thus referred to as prussian blue nanozymes (PBNZs).

New insights on health benefits, interactions with food components and potential application of marine-derived sulfated polysaccharides: A review.

Sulfated polysaccharides refer to polysaccharides containing sulfate groups on sugar units. In nature, sulfated polysaccharides are widely distributed in marine organisms, and the variation in sulfation sites, monosaccharide composition, and branched chain distribution among different species results in differences in the physicochemical properties and biological activities. From the latest perspective, this review summarized the types, structural characteristics, and potential health benefits of sulfated polysaccharides in marine foods.

Dual-responsive stem cell microspheres modified with BDNF for enhanced neural repair in diabetic erectile dysfunction.

We previously established an effective method to ameliorate erectile dysfunction (ED) using intracavernous injection (ICI) of mesenchymal stem cell (MSC) microspheres. However, the expression of a key neurotrophic factor, brain-derived neurotrophic factor (BDNF), was low in both MSCs and MSC microspheres, restricting the associated neural repair. Based on the hypoxia and oxidative stress microenvironments within cell spheroids and lesion areas, BDNF-expressing nanocomplexes that are dual-responsive to hypoxia and reactive oxygen species were designed to modify MSCs, achieving high BDNF expression in MSC spheroids.

Unveiling ADAMTS12: A Key Driver of Bladder Cancer Progression via COL3A1-Mediated Activation of the FAK/PI3K/AKT Signaling Pathway.

Bladder cancer (BCa) is a common and lethal disease characterized by high recurrence rates and limited treatment options.

Hsa_circ_0002005 aggravates osteosarcoma by increasing cell proliferation, migration, and invasion.

Emerging evidence suggests that circular RNAs (circRNAs), a class of non-coding RNAs, play a critical role in the progression of several cancers, including osteosarcoma (OS). In this study, we focused on a specific circRNA, hsa_circ_0002005, derived from the mesoderm-induced early response 1 family member 2 (MIER2) gene. We determined the expression levels of hsa_circ_0002005 in OS samples through the use of real-time quantitative polymerase chain reaction (RT-qPCR).

Downregulation of the PI3K/AKT/mTOR/MMP-13 Pathway for Promoting Interface Healing via Lubricating Microspheres.

Interface friction impedes tissue healing and stimulates interface cells to produce matrix metalloproteinases (MMPs); however, the precise mechanisms underlying matrix degradation, and the formation of fibrous scars remain unclear. This research involved the development of interface lubricating microspheres that inhibit the PI3K/AKT/mTOR signaling pathway in tenocytes. This inhibition significantly decreased MMP-13 expression and increased COL-1 production, thereby facilitating interface repair and regeneration.

Synergistic production of nitrogen-rich hydrochar and solid biofuels via co-hydrothermal carbonization of microalgae and macroalgae: when nitrogen circularity matters.

This work explores the synergies between N-rich (Chlorella pyrenoidosa) and N-deficient (Undaria pinnatifida) macroalgae for the production of N-containing hydrochar and solid biofuels via co-hydrothermal carbonization (co-HTC). The impact of the feedstock (each alga alone and all possible binary mixtures) was comprehensively assessed under different temperatures (180-260 °C) and times (60-240 min). The synergies between micro and macroalgae governed product distribution, nitrogen transformation pathways, and hydrochar quality, with these effects varying by processing conditions.

An efficient fungi-biochar-based system for advancing sustainable management of combined pollution.

Heavy metal (HM) contamination poses significant global environmental threats, impacting ecosystems, public health, and sustainable development. Fungi, as eco-friendly alternatives to chemical treatments, have the potential to reduce HM bioavailability in contaminated soils while promoting plant growth.

Deaggregation of micronized insoluble drugs by incorporating mannitol form α.

Micronization is frequently employed to increase the dissolution of poorly soluble drugs, but it easily led to powder aggregation and difficult to mix well on the micro level with poor content uniformity and erratic dissolution behavior. Mannitol is the most commonly used pharmaceutical excipient, and its β form (β-mannitol) is commercially available and extensively investigated, whereas form α (α-mannitol) remain poorly understood. Here, this study demonstrated that α-mannitol could significantly eliminate aggregation phenomena of micronized drugs (i.

The synergistic effects of microcredit access and agricultural technology adoption on maize farmer's income in Kenya.

Addressing global food security demands urgent improvement in agricultural productivity, particularly in developing economies where market imperfections are perverse and resource constraints prevail. While microcredit is widely acknowledged as a tool for economic empowerment, its role in facilitating agricultural technology adoption and improving agricultural incomes remains underexplored. This study examines the synergistic effects of microcredit access and agricultural technology adoption on the incomes of maize farmers in Kenya.

Agent-based simulation of trust networks and opportunistic behaviours of hydraulic infrastructure project participants.

Opportunistic behaviour has become a research hotspot in hydraulic infrastructure project management owing to its serious damage to the cooperation efficiency of all participants in a project. The trust networks formed by each participant can restrain opportunistic behaviour, but due to the dynamic evolution of the networks, its research should adopt a dynamic paradigm. The structure and evolution of trust networks can be simulated using computer simulations and modelling.
