Direct delivery of Cas9 protein complexed with guide RNA (gRNA) can mitigate these effects by limiting exposure time. We previously developed NanoMEDIC, a virus-like particle system shown to deliver Cas9/gRNA ribonucleoprotein (RNP) complexes both in vitro and in vivo. In the present study, we compared NanoMEDIC-mediated delivery with plasmid-based transfection using a gene excision reporter in the human embryonic kidney-derived cell line 293FT and the human glioblastoma-derived cell line NP-2. In this model, the DNA sequence targeted by Cas9/gRNA was derived from a human oncogenic retrovirus, human T-cell leukemia virus type I (HTLV-1). NanoMEDIC achieved efficient gene removal-editing with significantly lower Cas9 input per cell regardless of whether the target DNA was transiently transfected or integrated into chromosomal DNA. Sequencing of edited loci revealed that NanoMEDIC-mediated Cas9/gRNA delivery produced 58.3 – 87.5 % removal-edited DNA without insertions or deletions (indels), compared with 8.3 – 29.4 % using plasmid transfection. These data suggest a high editing precision of NanoMEDIC-mediated Cas9/gRNA delivery. This likely reflects the transient presence of Cas9, which enables rapid repair through non-homologous end joining (NHEJ) without prolonged nuclease activity. Collectively, our findings highlight the potential of NanoMEDIC for applications requiring precise, indel-free genome modifications and support its use as a safer alternative to DNA-based delivery or systems involving sustained Cas9 expression.</div></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"26 ","pages":"Article 100257"},"PeriodicalIF":0.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silica particles have a highly reactive surface that generates cell-damaging reactive oxygen species when fractured. The objective was to evaluate lung toxicity after exposure to silica coated with and without a water-soluble, organosilane-based coating (SIVO160). Male Sprague-Dawley rats were intratracheally instilled with silica (1 mg/rat), silica coated with SIVO160, SIVO160 alone, or saline (vehicle control). At 3, 10, 45, and 90 d after exposure, bronchoalveolar lavage (BAL) and histopathology were performed to assess lung toxicity. Whole blood was collected to evaluate systemic inflammation by differentiating circulating white blood cells. Also, samples of uncoated and coated silica were analyzed [(1) RapiFlex MALDI-ToF/ToF mass spectrometry; (2) digestion in phagolysosomal simulant fluid (PSF) and serum ultrafiltrate (SUF)] to confirm the SIVO160 coating on the surface of the silica particles after incubation in biological media. At each time point, silica significantly increased BAL fluid lactate dehydrogenase (lung injury) and the number of recovered lung macrophages and neutrophils (lung inflammation). These silica-induced elevations in lung toxicity were completely blocked at each time point when silica was coated with SIVO160 before exposure. At 45 d after exposure to uncoated silica, circulating total white blood cells, neutrophils, and lymphocytes were significantly elevated in the blood compared to the other groups. Lung exposure to silica pretreated with SIVO160 did not cause a significant elevation in any of the peripheral blood cell types at any time point when compared to the saline and SIVO160 alone. As assessed by mass spectrometry, multiple unique spectral peaks were detected on the surface of the silica+SIVO160 particle samples after an overnight incubation in saline. The peaks were absent in the uncoated silica sample spectra, confirming the coating’s presence on the particles. The time it took for removal by digestion of the SIVO160 coating on the silica was reflected by a short-term delay after incubation in both PSF and SUF, suggesting protection could be conveyed to lung cells by the coating during phagocytosis and particle deposition on lung tissue structures. Organosilane materials may be used as a possible mitigation strategy to potentially protect large numbers of workers exposed to respirable crystalline silica in multiple industries is important.</div></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"26 ","pages":"Article 100256"},"PeriodicalIF":0.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through D-optimal design methodology, the study examined key formulation variables including bile salt concentration, cholesterol content, bile salt type, edge activator type, and soybean phosphatidylcholine to bile salt ratio (SPC). These parameters were evaluated against key performance indicators: particle size (PS), zeta potential (ZP), and encapsulation efficiency (EE%).

The optimized bilosomal formulation demonstrated favorable characteristics with a particle size of 109.99 nm, zeta potential of -30.999 mV, and encapsulation efficiency of 94.54 %. Physicochemical characterization confirmed the absence of IRB-excipient interactions, while DSC analysis revealed IRB amorphization. TEM imaging validated spherical morphology of the formulated structures. The IRB-loaded bilosomes exhibited sustained biphasic release over 24 h, achieving relative bioavailability 1.42-fold and 1.30-fold higher compared to IRB solution and commercial formulation, respectively.

The binary photocatalyst comprising 0.05 g of ZnO per 1.0 g of BiOCl (denoted as 0.05ZnO/BiOCl) displayed the lowest photoluminescence signal, compared to the synthesized BiOCl and ZnO.

However, its poor stability and requirement for intravenous administration limit its clinical application. To address these limitations, novel formulations such as ufasomes (unsaturated fatty acid vesicles) have been developed to enhance caspofungin's stability and skin penetration. In this study, ufasomes were prepared using three oils: oleic acid, linoleic acid, and palmitoleic acid, along with caspofungin and cholesterol, using the thin-film method. Among the formulations, F34, composed of 500 mg palmitoleic acid and 10 mg cholesterol, exhibited promising results.
