However, its surgical treatment, in particular via trabeculectomy, can be complicated by fibrosis. In current clinical practice, application of the drug, Mitomycin C, prevents or delays fibrosis, but can lead to additional side effects, such as bleb leakage and hypotony. Previous <i>in silico</i> drug screening and <i>in vitro</i> testing has identified the known antibiotic, josamycin, as a possible alternative antifibrotic medication with potentially fewer side effects. However, a suitable ocular delivery mechanism for the hydrophobic drug to the surgical site does not yet exist. Therefore, the focus of this paper is the development of an implantable drug delivery system for sustained delivery of josamycin after glaucoma surgery based on crosslinked γ-cyclodextrin. γ-Cyclodextrin is a commonly used solubilizer which was shown to complex with josamycin, drastically increasing the drug's solubility in aqueous solutions. A simple γ-cyclodextrin crosslinking method produced biocompatible hydrogels well-suited for implantation. The crosslinked γ - cyclodextrin retained the ability to form complexes with josamycin, resulting in a 4-fold higher drug loading efficiency when compared to linear dextran hydrogels, and prolonged drug release over 4 days.</p>","PeriodicalId":11679,"journal":{"name":"Drug Delivery","volume":"31 1","pages":"2361168"},"PeriodicalIF":6.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11191840/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141426548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oxidative stress plays a crucial role in the pathogenesis of EBI. In this study, we synthesized antioxidant stress nanoparticles based on self-assembled oleanolic acid (OA) using the solvent volatilization method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) techniques were employed to analyze and understand the self-assembly mechanism of oleic acid nanoparticles (OA NPs). The TUNEL assay, Nissl staining, and brain water content measurements were conducted to investigate the impact of OA NPs on cortical neuronal injury. Additionally, Western blot analysis was performed to investigate the antioxidant stress mechanism of OA NPs. The result showed that OA NPs exhibited a spherical structure with an average diameter of 168 nm. The application of OA NPs in SAH has been found to contribute to the reduction of keap1 protein levels and an increase in the nuclear level of Nrf2. As a result, the transcription of antioxidant stress proteins, including HO1 and NQO1, is triggered. The activation of the antioxidant stress pathway by OA NPs ultimately leads to a decrease in neuron damage and an improvement in neurological dysfunction. In conclusion, we successfully designed and synthesized OA NPs that can efficiently target the site of SAH. These nanoparticles have demonstrated their potential as antioxidants for the treatment of SAH, offering significant clinical applications.</p>","PeriodicalId":11679,"journal":{"name":"Drug Delivery","volume":"31 1","pages":"2388735"},"PeriodicalIF":6.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11342817/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142016733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leptomeninges are the two membranous layers, called the arachnoid membrane and pia mater. The diffuse nature of LMD poses a challenge to its effective diagnosis and successful management. Furthermore, the predominant phenotype; solid masses or freely floating cells, has altering implications on the effectiveness of drug delivery systems. The standard of care is the intrathecal delivery of chemotherapy drugs but it is associated with increased instances of treatment-related complications, low patient compliance, and suboptimal drug distribution. An alternative involves administering the drugs systemically, after which they must traverse fluid barriers to arrive at their destination within the leptomeningeal space. However, this route is known to cause off-target effects as well as produce subtherapeutic drug concentrations at the target site within the central nervous system. The development of new drug delivery systems such as liposomal cytarabine has improved drug delivery in leptomeningeal metastatic disease, but much still needs to be done to effectively target this challenging condition.

These dual functional species, regarding their concurrent Pickering stabilization and active carrying/delivery capabilities, were formulated with different solid lipid and surfactant types, and the effect on the release and co-release modulation of two hydrophobic actives separately encapsulated within the lipid particles themselves and within the emulsion droplets was investigated. Disparities between the release profiles from the particles in aqueous dispersions or at an emulsion interface, were related to the specific lipid matrix composition. Particles composed of lipids with higher oil phase compatibility of the emulsion droplets were shown to exert less control over their release regulation ability, as were particles in the presence of surfactant micelles in the continuous phase. Irrespective of their formulation characteristics, all particles provided a level of active release control from within the emulsion droplets, which was dependant on the permeability of the formed interfacial layer. Specifically, use of a bulkier particle surfactant or particle sintering at the droplet interface resulted in more sustained droplet release rates.
