The current study explored brain damage that is associated with Dimethylbenz(a)anthracene (DMBA)-induced breast cancer. Induction was occurred in female Sprague-Dawley rats via 50 mg/kg DMBA followed by treatment with liposomal doxorubicin (5mg/kg) or titanium dioxide nanoparticles loaded doxorubicin (TiO2NP-DOX) (2mg/kg) for one month. Biochemical, molecular, and histopathological studies were accessed in addition to untargeted metabolomics study using gas chromatography-mass spectrometry. The current study revealed a significant reduction in the total antioxidant capacity besides a significant elevation of lipid peroxide values upon DMBA intoxication. Molecular quantification of FKBP5, A2m, BRAF and NF-kB mRNA gene expression revealed a significant reduction in both FKBP5 and A2M upon DMBA intoxication in contrast to a significant overexpression of BRAF and NF-kB mRNA gene expression. Meanwhile, liposomal doxorubicin and TiO2NP-DOX treated groups significantly modulate the aforementioned genes, with the superiority of TiO2NP-DOX treatment regimen. Protein expression of both AKT and PI3K recorded a significant elevation post DMBA intoxication. However, a highly significant downregulation was revealed in the protein expression post TiO2NP-DOX treatment. Interestingly, we found that various metabolites were downregulated whereas others were unregulated in DMBA intoxicated group. However, TiO2NP-DOX treatment regulated these altered metabolites. Histopathological examination of brain tissue confirmed the obtained results. In conclusion: TiO2NP-DOX could be a promising candidate for modulating oxidative stress, gene and protein expression malformation and oxidative brain injury associated with DMBA-induced carcinogenesis in rats and alters metabolites associated with mitigating inflammation and oxidative damage.
目前的研究探索了与二甲基苯(a)蒽(DMBA)诱导的乳腺癌相关的脑损伤。雌性Sprague-Dawley大鼠通过50 mg/kg DMBA诱导,然后用多柔比星(5mg/kg)脂质体或负载多柔比星(TiO2NP-DOX) (2mg/kg)的二氧化钛纳米颗粒治疗一个月。除了使用气相色谱-质谱法进行非靶向代谢组学研究外,还进行了生化、分子和组织病理学研究。目前的研究显示,在DMBA中毒后,除了脂质过氧化值显著升高外,总抗氧化能力显著降低。FKBP5、A2m、BRAF和NF-kB mRNA基因表达的分子定量显示,DMBA中毒后,FKBP5和A2m基因表达显著降低,而BRAF和NF-kB mRNA基因表达显著过表达。同时,多柔比星脂质体组和TiO2NP-DOX治疗组显著调节上述基因,具有TiO2NP-DOX治疗方案的优势。DMBA中毒后,AKT和PI3K蛋白表达均显著升高。然而,在TiO2NP-DOX处理后,蛋白表达出现了高度显著的下调。有趣的是,我们发现DMBA中毒组多种代谢物下调,而其他代谢物不受调节。然而,TiO2NP-DOX处理调节了这些改变的代谢物。脑组织的组织病理学检查证实了上述结果。综上所述,TiO2NP-DOX可能是一个有希望的候选者,可以调节与dmba诱导的癌变有关的大鼠氧化应激、基因和蛋白质表达畸形和氧化性脑损伤,并改变与减轻炎症和氧化损伤相关的代谢物。

Inhalation of respirable crystalline silica can cause pulmonary fibrosis and inflammation. 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.
吸入可吸入的结晶二氧化硅可引起肺纤维化和炎症。二氧化硅颗粒具有高度活性的表面,当破裂时产生破坏细胞的活性氧。目的是评估暴露于有或没有水溶性有机硅基涂层(SIVO160)的二氧化硅后的肺毒性。雄性Sprague-Dawley大鼠气管内灌注二氧化硅(1 mg/只)、二氧化硅包被SIVO160、单独SIVO160或生理盐水(对照)。暴露后3、10、45和90 d,进行支气管肺泡灌洗(BAL)和组织病理学评估肺毒性。采集全血,通过区分循环白细胞来评估全身性炎症。(1) RapiFlex MALDI-ToF/ToF质谱分析;(2)在吞噬溶酶体模拟液(PSF)和血清超滤液(SUF)中进行消化,以确认生物培养基孵育后二氧化硅颗粒表面的SIVO160涂层。在每个时间点,二氧化硅显著增加BAL液乳酸脱氢酶(肺损伤)和恢复的肺巨噬细胞和中性粒细胞(肺炎症)的数量。当暴露前用SIVO160包覆二氧化硅时,这些二氧化硅引起的肺毒性升高在每个时间点都被完全阻断。暴露于未涂覆二氧化硅45天后,与其他组相比,血液中循环的白细胞总数、中性粒细胞和淋巴细胞显著升高。与单独使用生理盐水和SIVO160相比,肺暴露于经SIVO160预处理的二氧化硅在任何时间点都没有引起任何外周血细胞类型的显著升高。通过质谱分析,在生理盐水中孵育过夜后,二氧化硅+SIVO160颗粒样品表面检测到多个独特的光谱峰。在未涂覆的二氧化硅样品光谱中没有峰,证实了涂层在颗粒上的存在。在PSF和SUF中孵育后,SIVO160涂层通过消化去除二氧化硅所需的时间被反映为短期延迟,这表明在肺组织结构的吞噬和颗粒沉积过程中,涂层可以传递给肺细胞保护作用。有机硅烷材料可作为一种可能的缓解策略,以潜在地保护多个行业中暴露于可吸入结晶二氧化硅的大量工人,这一点很重要。

Fe3O4/BiOCl photocatalyst with magnetic recovery property for solar-light-responsive removal of Rhodamine B dye 具有磁回收性能的Fe3O4/BiOCl光催化剂对罗丹明B染料的光响应去除
Q2 Pharmacology, Toxicology and Pharmaceutics Pub Date : 2025-11-01 Epub Date: 2025-09-25 DOI: 10.1016/j.onano.2025.100260

Binary Fe3O4/BiOCl photocatalyst was fabricated successfully via a facile ultrasonic route. The magnetic Fe3O4/BiOCl was used for solar-light-driven detoxification of Rhodamine B (RhB) dye. The prepared binary photocatalyst displayed mainly the diffraction peaks of BiOCl. The energy gap of BiOCl and Fe3O4/BiOCl was 3.37 eV, and 2.55 eV, respectively. The Fe3O4/BiOCl photocatalyst revealed lower fluorescence intensity, compared to the pristine BiOCl, indicating the enhanced carrier separation rate. The result corelates well with the improvement in photocatalytic activity of the magnetic Fe3O4/BiOCl photocatalyst. High photocatalytic efficiency of 100% was achieved after 90 min of sunlight irradiation. The degradation of RhB dye fits nicely with the first-order kinetic model revealing the maximum rate constant of 0.0113 min–1. The binary photocatalyst still maintains the excellent photodegradation activity after the fifth cycle of use. The trapping technique reveals that photogenerated electrons and superoxide anion radicals play a key role in RhB detoxification. The present work provides a promising way to generate the sunlight-active semiconducting catalyst, with magnetic separable property, for detoxification of RhB dye in an aqueous phase.
采用简易超声法成功制备了Fe3O4/BiOCl二元光催化剂。磁性Fe3O4/BiOCl用于罗丹明B (RhB)染料的太阳能解毒。制备的二元光催化剂主要显示BiOCl的衍射峰。BiOCl和Fe3O4/BiOCl的能隙分别为3.37 eV和2.55 eV。与原始BiOCl相比,Fe3O4/BiOCl光催化剂的荧光强度较低,表明载体分离率提高。该结果与磁性Fe3O4/BiOCl光催化剂的光催化活性的提高有良好的相关性。光照90 min后,光催化效率达到100%。RhB染料的降解符合一级动力学模型,最大速率常数为0.0113 min-1。二元光催化剂在第五次循环使用后仍保持良好的光降解活性。捕获技术揭示了光生电子和超氧阴离子自由基在RhB解毒过程中起关键作用。本研究为制备具有磁性可分离性质的光活性半导体催化剂提供了一种很有前途的方法,用于RhB染料在水相中的解毒。

Chitosan-functionalized selenium nanoparticles (CS-SeNPs) integrate selenium’s redox-active anticancer potential with chitosan’s stabilization, mucoadhesion, and ligand-ready surface to enable tumor-selective delivery. This review consolidates advances in chemical, physical, and green syntheses; relates processing to size, charge, colloidal stability, and drug loading; and maps these attributes to biodistribution, cellular uptake, and controlled release. Emphasis is placed on modified chitosan derivatives that confer pH or redox responsiveness, enhanced permeability and retention, active targeting, and co-delivery of chemotherapeutics or photosensitizers. Anticancer mechanisms encompass mitochondrial apoptosis, ROS modulation, cell-cycle arrest, anti-metastatic activity, and chemo- or photo-synergy. A critical comparison with metal-oxide platforms and discussion of environmental fate, biofilm reactor data, hemocompatibility, and immunotoxicity delineate benefits and remaining risks. Key translational priorities include scalable green synthesis, robust physicochemical and release specifications, in vivo exposure–response models, and regulatory-grade safety packages. CS-SeNPs thus represent a credible path toward precision oncology.

Myco-nanotechnology at the crossroads: eco-friendly synthesis, agricultural applications, and AI-driven risk mitigation of fungal-derived nanoparticles 十字路口的微生物纳米技术:生态友好合成、农业应用和人工智能驱动的真菌衍生纳米颗粒风险缓解
Q2 Pharmacology, Toxicology and Pharmaceutics Pub Date : 2025-09-01 Epub Date: 2025-08-27 DOI: 10.1016/j.onano.2025.100254

Fungal-based nanotechnology is emerging as a promising and sustainable approach in agriculture, environmental cleanup, and biotechnology. Nanoparticles produced by fungi known as Myco-nanoparticles offer a greener method of synthesis, along with good stability and strong biological activity. However, their increasing use has raised concerns about possible environmental risks and long-term effects. This review highlights recent advances in the eco-friendly production of Myco-nanoparticles and their potential to support plant growth, improve nutrient uptake, and boost resistance to stress and disease. While small amounts of these particles may be helpful, higher doses can lead to harmful effects such as oxidative stress and damage to plant DNA.

Binary photocatalyst based on ZnO/BiOCl was constructed very easily using a solvothermal route by addition of solid ZnO to the reaction mixture during the formation of BiOCl. The two-component heterojunction was then applied for sunlight-active removal of tetracycline (TC) drug. The synthesized heterostructure showed mainly the characteristic XRD peaks of BiOCl with the band gap of 3.50 eV, compared to 3.30 eV of the bare BiOCl. 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. This indicates the greatest carrier separation rate at the interface detected in the binary ZnO/BiOCl, compared to other photocatalysts. The result corelates well with the maximum photoactivity detected in the 0.05ZnO/BiOCl. High photocatalytic performance of 100% was detected under 100 min of UV light (135 W, a mercury lamp). In addition, 98% removal of TC under natural sunlight was also achieved within 240 min. The photodegradation of TC agrees perfectly with the first-order kinetic model providing a rate constant of 0.0546 min–1. This is about 1.9 times higher than those obtained from either ZnO or BiOCl photocatalysts. The binary ZnO/BiOCl heterostructure still exhibits the promising photodegradation efficiency after five runs. The scavenger experiment reveals that the photogenerated electrons are the major species which play a crucial role in TC degradation. This work emphasizes a facile route to fabricate the two-component heterostructure, with promising performance, for removal of TC antibiotic in natural water.
在BiOCl形成过程中,通过在反应混合物中加入固体ZnO,可以很容易地构建出基于ZnO/BiOCl的二元光催化剂。然后将双组分异质结应用于日光活性脱除四环素(TC)药物。合成的异质结构主要表现为BiOCl的特征XRD峰,带隙为3.50 eV,而裸BiOCl的带隙为3.30 eV。与合成的BiOCl和ZnO相比,含有0.05 g ZnO/ 1.0 g BiOCl的二元光催化剂(表示为0.05ZnO/BiOCl)的光致发光信号最低。这表明与其他光催化剂相比,二元ZnO/BiOCl在界面处检测到最大的载流子分离率。该结果与在0.05ZnO/BiOCl中检测到的最大光活性具有良好的相关性。在紫外光(135 W,汞灯)照射100 min下,检测到100%的高光催化性能。另外,在240 min内,TC的去除率也达到98%。TC的光降解完全符合一级动力学模型,速率常数为0.0546 min - 1。这比使用ZnO或BiOCl光催化剂得到的结果高1.9倍。经过5次实验后,ZnO/BiOCl二元异质结构仍表现出良好的光降解效率。清道夫实验表明,光生电子是在TC降解过程中起关键作用的主要电子种。本工作强调了一种简单的制备双组分异质结构的方法,该方法具有良好的性能,可用于去除天然水中的TC抗生素。

Recent progress in supersaturation-based SNEDDS: Formulation, mechanism, and biopharmaceutical performance 过饱和型SNEDDS的最新进展:配方、机制和生物制药性能
Q2 Pharmacology, Toxicology and Pharmaceutics Pub Date : 2025-09-01 Epub Date: 2025-07-16 DOI: 10.1016/j.onano.2025.100252

This review highlights supersaturation-based SNEDDS (self-nanoemulsifying drug delivery systems), focusing on formulation strategies, supersaturation generation, stabilization mechanisms, and their impact on drug release, permeation, and bioavailability. The discussion is based on articles from reputable databases published between 2020 and 2025. Supersaturation-based SNEDDS are classified into supersaturable and supersaturated types, differing in the onset of supersaturation and approaches to precipitation inhibition. Widely developed for BCS Class II and IV drugs, these systems increase thermodynamic activity and enhance drug absorption in the gastrointestinal tract. Although metastable and prone to precipitation, precipitation inhibitors (PIs) such as HPMC or PVP can stabilize the supersaturated state, suppressing nucleation and crystal growth. Proper screening is essential to identify the most suitable PIs for each formulation. Supersaturable and supersaturated SNEDDS have improved drug release and intestinal permeation, enhancing bioavailability compared to pure drugs, conventional SNEDDS, or marketed formulations.
这篇综述重点介绍了基于过饱和的自纳米乳化给药系统(SNEDDS),重点是配方策略、过饱和的产生、稳定机制以及它们对药物释放、渗透和生物利用度的影响。该讨论基于2020年至2025年间发表的知名数据库中的文章。基于过饱和的SNEDDS分为过饱和型和过饱和型,在过饱和的开始和沉淀抑制的方法上有所不同。广泛用于BCS II类和IV类药物,这些系统增加了热力学活性并促进了药物在胃肠道的吸收。虽然亚稳且容易析出,但沉淀抑制剂(PIs)如HPMC或PVP可以稳定过饱和状态,抑制成核和晶体生长。适当的筛选对于确定每种制剂最合适的pi至关重要。与纯药物、传统SNEDDS或上市制剂相比,过饱和和过饱和SNEDDS改善了药物释放和肠道渗透,提高了生物利用度。

Periodontitis is a chronic inflammatory disease requiring localized drug delivery for sustained therapeutic action. Conventional treatments face challenges such as a rapid drug clearance and poor bioavailability. This study develops and evaluates an azithromycin-loaded niosomal thermoresponsive gel (AZG) to enhance drug retention and treatment efficacy. Azithromycin-loaded niosomes (AZN) were optimized using a 32 full factorial design with Span 60 and cholesterol, achieving nanoscale size, stable zeta potential, and high drug encapsulation. The optimized AZN was incorporated into a poloxamer 407-hyaluronic acid gel, ensuring in situ gelation and prolonged drug retention. AZG exhibited favorable gelation, biocompatibility, accelerated wound closure, enhanced cell proliferation, and significant anti-inflammatory effects (twofold IL-1β and sixfold TNF-α reduction, p < 0.05). By integrating sustained drug release with antibacterial and anti-inflammatory properties, AZG presents a promising adjunctive therapy for periodontitis, addressing key limitations of existing treatments.

Effect of unsaturated fatty acids on the topical delivery of caspofungin ufasomes: In vitro/ Ex vivo evaluation and anti-fungal study against Candida albicans 不饱和脂肪酸对caspofunins ufasomes局部递送的影响:体外/体外评估和抗白色念珠菌的研究
Q2 Pharmacology, Toxicology and Pharmaceutics Pub Date : 2025-07-01 Epub Date: 2025-06-25 DOI: 10.1016/j.onano.2025.100250

Cutaneous candidiasis presents a considerable challenge in today’s medical landscape, particularly for patients with weakened immune systems or chronic illnesses. As antifungal resistance continues to rise, the development of new topical therapies has become increasingly urgent. Caspofungin (CSP), an echinocandin antifungal, exhibits fungicidal activity against Candida species by inhibiting β-1,3-d-glucan synthase, a key enzyme in fungal cell wall synthesis. 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. It demonstrated a particle size (PS) of 87.65± 2.65 nm, a polydispersity index (PDI) of 0.22 ± 0.00, a zeta potential (ZP) of -7.46± 0.4 mV, a drug content of 97 ± 1.34 %, and an encapsulation efficiency (EE %) of 92 ± 0.82 %. Furthermore, the optimized formulation F34 showed a sustained drug release of 81.5 ± 0.4 over 600 min (10 h) compared to 100 %±0.01 of caspofungin. The permeation of F34 in 600 min (10 h) was 94 %±0.81 compared to the caspofungin 87.85 %±0.85. The antifungal activity showed that the inhibition zone diameter, MIC and MBC for caspofungin-loaded ufasomes was 29 mm±0.8, 0.153 μg/mL±0.01, 0.283 μg/mL±0.02 compared to 25 mm±0.8, 0.214 μg/mL±0.01, 0.409±0.01 for pure caspofungin. The histopathological study revealed a positive response towards the optimized formulation. In conclusion, this optimized formulation holds potential as a novel therapeutic approach for treating topical fungal infections.
皮肤念珠菌病在当今的医疗领域提出了相当大的挑战,特别是对于免疫系统较弱或慢性疾病的患者。随着抗真菌耐药性的持续上升,开发新的局部治疗方法变得越来越紧迫。Caspofungin (CSP)是一种棘白菌素抗真菌药物,通过抑制真菌细胞壁合成的关键酶β-1,3-葡聚糖合成酶,对念珠菌具有杀真菌活性。但其稳定性差,需要静脉给药,限制了其临床应用。为了解决这些限制,新的配方如不饱和脂肪酸囊泡(不饱和脂肪酸囊泡)已经被开发出来,以提高caspofunins的稳定性和皮肤渗透性。本研究以油酸、亚油酸、棕榈油酸三种油类为原料,与caspofunins、胆固醇为原料,采用薄膜法制备ufasomes。其中,由500 mg棕榈油酸和10 mg胆固醇组成的F34具有良好的效果。其粒径(PS)为87.65±2.65 nm,多分散指数(PDI)为0.22±0.00,ζ电位(ZP)为-7.46±0.4 mV,药含量为97±1.34%,包封率(EE %)为92±0.82%。优化后的F34在600 min (10 h)内的缓释量为81.5±0.4,而卡泊芬素的缓释量为100%±0.01。F34在600 min (10 h)内的通透率为94%±0.81,而caspofungin为87.85%±0.85。抑菌活性表明,载caspofunins的抑菌带直径、MIC和MBC分别为29 mm±0.8、0.153 μg/mL±0.01、0.283 μg/mL±0.02,而纯caspofunins的抑菌带直径、MIC和MBC分别为25 mm±0.8、0.214 μg/mL±0.01、0.409±0.01。组织病理学研究显示了对优化配方的积极反应。总之,这个优化的配方具有潜力作为治疗局部真菌感染的一种新的治疗方法。
