Nickel oxide nanoparticles (NiO NPs) are highly redox active nanoparticles. They can cause acute and chronic inflammation in rat lungs. Unlike the gut microbiome, the association between the lung microbiome’s role and pulmonary inflammatory response to inhaled nanoparticles remains largely unexplored. We aimed to explore the interaction between the lung microbiome and inflammatory responses in rats exposed to NiO NPs. Thirty female Wistar rats were randomly categorized into control and low- (50 cm2/rat), and high- (150 cm2/rat) dose NiO NPs exposure groups. NiO NPs were intratracheally instilled, and cytological, biochemical, proinflammatory cytokine, and lung microbiome analyses of bronchoalveolar lavage fluid were performed at 1 day and 4 weeks after instillation. NiO NPs caused a neutrophilic and lymphocytic inflammatory response in rat lung. We demonstrated that exposure to NiO NPs can alter the lung microbial composition in rats. In particular, we found that more Burkholderiales are present in the NiO NPs exposure groups than in the control group at 1 day after instillation. Dysbiosis in the lung microbiome is thought to be associated with acute lung inflammation. We also suggested that Burkholderiales may be a key biomarker associated with lung neutrophilic inflammation after NiO NPs exposure.

Objective: Despite the widespread of nickel oxide nanoparticles (NiO NPs) and their benefits in all fields, they have many negative effects on human life, especially expectant mothers and their fetus. The purpose of this study was to investigate the possible maternal and developmental toxicity-induced by NiO NPs administration during gestation. Methods: Three groups of pregnant rats were administered orally during days 5–19 of gestation, the pregnant rats were haphazardly designed into three groups (six rat/group), as follows: Control group and NiO NPs administered groups, low (4 mg/kg), and high (8 mg/kg) doses. Results: NiO NPs administration resulted in severe maternal and developmental toxicity which included reduction in uterine weight, mother weight gain, the average weight of placenta, the number corpora lutea, implantation sites, and the number of live fetuses. Furthermore, high pre/ postimplantation, fetal growth retardation, and morphological and skeletal anomalies, an elevation in liver and brain DNA damage in both mother and fetus, and histopathological alterations in different tissues (placenta, liver, kidney, and brain) of pregnant rats and fetuses. Lipid peroxidation showed a significant elevation in maternal, fetal liver, and brain tissues of NiO NPs ‐administered rats. Furthermore, glutathione content and catalase activity were decreased in both tissues of NiO NPs‐administered rats. Conclusion: Finally, the detrimental impacts of NiO NPs in dams and fetuses probably through its potential generation of reactive oxygen species.

The article presents in an experiment obtained principal results based on repeated low-level inhalation exposures of laboratory animals (white rats, outbred) to nickel oxide nanoparticles with a diameter of (23 ± 5) nm, 4 hours a day, 5 times a week for up to 10 months in a «nose only» installation. It was shown that non-specific body reactions to the action of NiO NPs include: diverse manifestations of systemic toxicity with a particularly pronounced influence on liver and kidney function, redox balance, damage to some areas of brain tissue, associated with proven movement of the nanoparticles themselves from the nasal mucosa along the olfactory tract; some cytological signs of probable development for allergic syndrome; paradoxically low severity of pulmonary pathology by pneumoconiotic type explained by a small chronic delay of nanoparticles in the lungs; the genotoxic effect of the organismal level, even at those low levels of chronic exposure, at which systemic toxicity is rather poorly. Along with that, NiO NPs also induce phase-stimulation of erythropoiesis, which is relatively specific for the toxic nickel effects.

The Impact

Nickel nanoparticles (Ni-NPs) have advantageous applications in the industry; however, little is known of their adverse effects on biological tissues. In the present study, the ground beetle Blaps polycresta was employed as a sensitive indicator for nickel oxide nanoparticles (NiO-NPs) toxicity. Adult male beetles were injected with six dose levels of NiO-NPs (0.01, 0.02, 0.03, 0.04, 0.05, and 0.06 mg/g body weight). Mortality was reported daily over 30 days under laboratory conditions to establish an LD50. Nickel was detected in the testicular tissues of the beetles using X-ray analysis and transmission electronic microscopy. Beetles treated with the sublethal dose of 0.02 mg/g were selected to observe molecular, cellular, and subcellular changes. Gene transcripts of HSP70, HSP90, and MT1 were found to be increased >2.5-, 1.5-, and 2-fold, respectively, in the treated group compared with the controls. Decreased gene expression of AcPC01, AcPC02, and AcPC04 (≤1.5-, ≤2-, and < 2.5-fold, respectively, vs. controls) also were reported in the treated group. Under light microscopy, various structural changes were observed in the testicular tissues of the treated beetles. Ultrastructure observations using scanning and transmission electron microscopy showed severe damage to the subcellular organelles as well as deformities of the heads and flagella of the spermatozoa. Therefore, the present study postulated the impact of NiO-NPs in an ecological model.

In the present study, nickel oxide nanoparticles (NiO NPs) were evaluated as an antibacterial and anticancer agent. The nanoparticles of nikel oxide were synthesized using aloe vera leaves extract and characterized with AFM (showing an average diameter of 45.11 nm), XRD and FE-SEM analyses. Three different concentrations (125, 250 and 500 µg/ml) were prepared from the synthesized NiO NPs and investigated for their potential antibacterial activity against both Enterococcus faecalis (Gram-positive bacteria) and Acinobacter baumannii (Gram-negative bacteria). While cytotoxicity and apoptotic activity were measured on both MCF-7 and AMJ13 cancer cell lines by  MTT and caspase-9 luminescence assays. The results showed that NiO NPs inhibit bacterial growth, as indicated by large inhibition zones  against both tested bacteria, with all studied concentrations. Moreover, the results of cytotoxicity and caspase-9 activity assays were in concordance with those of  antibacterial activity, showing high cytotoxicity and apoptotic effects against both of the studied cancer cell lines and with all the tested concentrations of NiO NPs. Both the antibacterial and anticancer activities of NiO NPs were dose-dependent.

In this study, ultrafine nickel oxide nanoparticles (NiO NPs) were well synthesized using a simple wet chemical method under low temperature, 300 °C. An Ni(OH)2 precursor was well precipitated by dropping NH4OH into an Ni(Ac)2 solution. TG-DTA showed that the weight of the precipitate decreases until 300 °C; therefore, the precursor was heat-treated at 300 °C. X-ray diffraction (XRD) patterns indicated that hexagonal-structured NiO NPs with (200) preferred orientation was synthesized. In addition, BET specific surface area (SSA) and HRTEM analyses revealed that spherical NiO NPs were formed with SSA and particle size of 60.14 m2/g and ca. 5–15 nm by using the low temperature method. FT-IR spectra of the NiO NPs showed only a sharp vibrating absorption peak at around 550 cm−1 owing to the Ni-O bond. Additionally, in UV-vis absorption spectra, the wavelength for absorption edge and energy band gap of the ultrafine NiO NPs was 290 nm and 3.44 eV.

Abstract Direct dyes are used in different textile operations and processings. The textile industries are disposing of unused direct dyes into the aquatic environment which is posing a serious alarming threat to aquatic lives. The current study deals with the synthesis of nickel oxide nanoparticles using Allium cepa peels aqueous extract. Nickel oxide nanoparticles (NiO-NPs) were characterized by SEM. Synthesized NiO-NPs were used to remove Congo red direct dye. Various experimental factors like concentration of dye & nanoparticles, pH, and temperature were optimized. Congo red direct dye was decolorized up to 90% at optimized conditions (Congo Red Direct dye concentration 0.02%, catalyst dose 0.003 g·L−1, pH 6, and temperature (50 °C). The real textile industry effluent disclosed 70% decolorization at optimized conditions. The percent reduction in TOC and COD were found to be 73.24% and 74.56%, in the case of congo red dye catalytic treatment & the percent reduction in TOC and COD were found to be 62.47% and 60.23%, respectively in the treatment of textile effluent using nickel oxide nanoparticles as a catalyst. Treated and untreated dye samples were exposed to FTIR and UV-Visible spectral analyses too. The reaction products were studied by degradation pathway.
