Abstract
Delivering macromolecules across the skin poses challenges due to the barrier properties of stratum corneum. Different strategies have been reported to cross this barrier, such as chemical penetration enhancers and physical methods like microneedles, sonophoresis, electroporation, laser ablation, etc. Herein, we explored a cationic lipo-polymeric nanocarrier to deliver a model protein across the skin. A cationic amphiphilic lipo-polymer was used to prepare blank nanoplexes, which were subsequently complexed with anionic fluorescein-tagged bovine serum albumin (FITC-BSA). Blank nanoplexes and FITC-BSA complexed nanoplexes showed sizes of 93.72 ± 5.8 (PDI-0.250) and 145.9 ± 3.2 nm (PDI-0.258), respectively, and zeta potentials of 25.6 ± 7.0 mV and 9.17 ± 1.20 mV. In vitro cell culture, and toxicity studies showed optimal use of these nanocarriers, with hemocompatibility data indicating non-toxicity. Ex vivo skin permeation analysis showed a skin permeation rate of 33% after 24 h. The optimized formulation was loaded in a carbopol-based gel that exhibits non-Newtonian flow characteristics with shear-thinning behavior and variable thixotropy. The nanoplexes delivered via gel demonstrated skin permeation of 57% after 24 h in mice skin ex vivo. In vivo skin toxicity testing confirmed the low toxicity profile of these nanocarriers. These results are promising for the transdermal/dermal delivery of macromolecules, such as protein therapeutics, using nanoplexes.

The Role of Phthalocyanine-Gold Nanoconjugates (Pc-Au NCs) in Ameliorating the Hepatic and Renal Toxicity-Induced by Silver Nanoparticles (Ag NPs) in Male Rats. Biol Trace Elem Res 2024:10.1007/s12011-024-04209-1. [PMID: 38739260 DOI: 10.1007/s12011-024-04209-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2023] [Accepted: 04/24/2024] [Indexed: 05/14/2024]
Abstract
Recently, gold nanoparticles (Au Nps) have gained tremendous attention for its unique properties as a safe nanocarrier for delivering drugs that are used in different disease diagnoses. Although silver nanoparticles (Ag NPs) have been generally applied due to their strong antibacterial, antiviral, antifungal, and antimicrobial properties, their toxicity is a subject of sustained debate, thus requiring further studies. The present study aims to evaluate the potential protective effect of gold nanoparticles and phthalocyanine-gold nanoconjugates (Pc-Au NCs) against the hepatorenal toxicity of silver nanoparticles in male rats. Herein, 60 adult male Rattus norvegicus rats were divided into six equal groups (n = 10/group); the first group was kept as control, the second received gold nanoparticles (Au NPs) intraperitoneally (10 µg/kg) daily for 3 weeks, the third group is gold-phthalocyanine (Pc-Au) group where rats were injected intraperitoneally with gold-phthalocyanine for 3 weeks (10 µg/kg), the fourth group received silver nanoparticles (Ag NPs) (4 mg/kg) daily intraperitoneally for 3 weeks, the fifth group is silver + gold nanoparticles group (Ag + Au), and the sixth is silver + gold-phthalocyanine nanoconjugates (Ag + Pc-Au) group in which rats were intraperitoneally injected firstly with Ag NPs (4 mg/kg) for 3 weeks then with gold or gold-phthalocyanine for another 3 weeks (10 µg/kg). Our results revealed that Ag NPs could increase the serum AST, ALT, ALP, urea, creatinine, and lipid profile and significantly decreased the total protein and albumin. Moreover, histopathological alterations detected in the kidney and the liver of the Ag NPs group included vascular congestion, inflammatory cell infiltration, and tissue distortion. Alongside, exposure to Ag NPs induces hepatic and renal oxidative stress by suppressing the antioxidant-related genes including glutathione peroxidase 1 (gpx1), superoxide dismutase (sod), and catalase (cat). Ag NPs also upregulated the hepatic and renal genes involved in inflammation such as the interleukin-6 (il-6) and tumor necrosis factor-α (tnf-α), nuclear factor kappa B (nf-κβ), apoptosis such as the BCL2 associated X (bax), casp3, and other related to metabolism including asparagine synthetase (asns), suppressor of cytokine signaling 3 (socs3), MYC proto-oncogene (myc), and C-C motif chemokine ligand 2 (ccl2). On the other hand, treatment with Au NPs and Pc-Au NCs could effectively ameliorate the hepatorenal damages induced by Ag NPs and improve liver and kidney architecture and function, especially in the Pc-Au NCs group. Briefly, our study revealed the underlined mechanism of Ag NPs hepatotoxic and nephrotoxic effects and that Pc-Au NCs could alleviate these adverse impacts via their anti-oxidative, anti-apoptotic, and anti-inflammatory activities.

Abstract
The current study was conducted to investigate the possible ameliorative role of zinc nanoparticles (Zn NPs) against silver nanoparticles (Ag NPs)-induced oxidative and apoptotic brain damage in adult male rats. Twenty-four mature Wistar rats were randomly and equally divided into four groups: control group, Ag NPs group, Zn NPs group, and Ag NPs + Zn NPs group. Rats were exposed to Ag NPs (50 mg/kg) and/or Zn NPs (30 mg/kg) daily by oral gavage for 12 weeks. The results revealed that exposure to Ag NPs significantly increased malondialdehyde (MDA) content, decreased catalase and reduced glutathione (GSH) activities, downregulated the relative mRNA expression of antioxidant-related genes (Nrf-2 and SOD), and upregulated the relative mRNA expression of apoptosis-related genes (Bax, caspase 3 and caspase 9) in the brain tissue. Furthermore, severe neuropathological lesions with a substantial increase in the caspase 3 and glial fibrillary acidic protein (GFAP) immunoreactivity were observed in the cerebrum and cerebellum of Ag NPs-exposed rats. Conversely, co-administration of Zn NPs with Ag NPs significantly ameliorated most of these neurotoxic effects. Collectively, Zn NPs can be used as a potent prophylactic agent against Ag NPs-induced oxidative and apoptotic neural damage.

Abstract
Nanomaterials (NM) arouse interest in various fields of science and industry due to their composition-tunable properties and the ease of modification. They appear currently as components of many consumer products such as sunscreen, dressings, sports clothes, surface-cleaning agents, computer devices, paints, as well as pharmaceutical and cosmetics formulations. The use of NPs in products for topical applications improves the permeation/penetration of the bioactive compounds into deeper layers of the skin, providing a depot effect with sustained drug release and specific cellular and subcellular targeting. Nanocarriers provide advances in dermatology and systemic treatments. Examples are a non-invasive method of vaccination, advanced diagnostic techniques, and transdermal drug delivery. The mechanism of action of NPs, efficiency of skin penetration, and potential threat to human health are still open and not fully explained. This review gives a brief outline of the latest nanotechnology achievements in products used in topical applications to prevent and treat skin diseases. We highlighted aspects such as the penetration of NPs through the skin (influence of physical-chemical properties of NPs, the experimental models for skin penetration, methods applied to improve the penetration of NPs through the skin, and methods applied to investigate the skin penetration by NPs). The review summarizes various therapies using NPs to diagnose and treat skin diseases (melanoma, acne, alopecia, vitiligo, psoriasis) and anti-aging and UV-protectant nano-cosmetics.

Abstract
Despite the extraordinary use of silver nanoparticles (AgNPs) in medicinal purposes and the food industry, there is rising worry about potential hazards to human health and the environment. The existing study aims to assess the hepatotoxic effects of different dosages of AgNPs by evaluating hematobiochemical parameters, oxidative stress, liver morphological alterations, immunohistochemical staining, and gene expression to clarify the mechanism of AgNPs' hepatic toxic potential. Forty male Sprague Dawley rats were randomly assigned into control and three AgNPs intraperitoneally treated groups 0.25, 0.5, and 1 mg/kg b.w. daily for 15 and 30 days. AgNP exposure reduced body weight, caused haematological abnormalities, and enhanced hepatic oxidative and nitrosative stress with depletion of the hepatic GSH level. Serum hepatic injury biomarkers with pathological hepatic lesions where cholangiopathy emerges as the main hepatic alteration in a dosage- and duration-dependent manner were also elevated. Furthermore, immunohistochemical labelling of apoptotic markers demonstrated that Bcl-2 was significantly downregulated while caspase-3 was significantly upregulated. In conclusion, the hepatotoxic impact of AgNPs may be regulated by two mechanisms, implying the apoptotic/antiapoptotic pathway via raising BAX and inhibiting Bcl-2 expression levels in a dose-dependent manner. The TGF-β1 and α-SMA pathway which triggered fibrosis with incorporation of iNOS which consequently activates the inflammatory process were also elevated. To our knowledge, there has been no prior report on the experimental administration of AgNPs in three different dosages for short and long durations in rats with the assessment of Bcl-2, BAX, iNOS, TGF-β1, and α-SMA gene expressions.

Abstract
The present review focuses on the potential use of silver nanoparticles in the therapy of diseases caused by antibiotic-resistant bacteria. Such bacteria are known as “superbugs”, and the most concerning species are Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus (methicillin and vancomycin-resistant), and some Enterobacteriaceae. According to the World Health Organization (WHO), there is an urgent need for new treatments against these “superbugs”. One of the possible approaches in the treatment of these species is the use of antibacterial nanoparticles. After a short overview of nanoparticle usage, mechanisms of action, and methods of synthesis of nanoparticles, emphasis has been placed on the use of silver nanoparticles (AgNPs) to combat the most relevant emerging resistant bacteria. The toxicological aspects of the AgNPs, both in vitro using cell cultures and in vivo have been reviewed. It was found that toxic activity of AgNPs is dependent on dose, size, shape, and electrical charge. The mechanism of action of AgNPs involves interactions at various levels such as plasma membrane, DNA replication, inactivation of protein/enzymes necessary, and formation of reactive oxygen species (ROS) leading to cell death. Researchers do not always agree in their conclusions on the topic and more work is needed in this field before AgNPs can be effectively applied in clinical therapy to combat multi-drug resistant bacteria.

Abstract
Each year, growing demand for silver nanoparticles (AgNP) contributes to the search for alternative methods of their production. Stable AgNP with antibacterial properties, low toxicity to the environment and living organisms are especially valued. In the study presented here, an attempt was made to assess the toxicity of two AgNP solutions produced using the HVAD method to the Chinchilla lanigera genome. The AgNO3 solution was the indicator and reference for the harmfulness of AgNP. The study was carried out in vitro on bone marrow cells isolated from Chinchilla lanigera bones. The genotoxicity was assessed by comet assay, following the treatment of cells with three silver solutions: unstable and sodium citrate-stabilized silver nanoparticles, as well as silver nitrate at three concentrations (5, 10 and 20 µg/L), after 3, 6 and 24 h. Based on the percentage of the DNA content in the comet tail and the tail moment, an increase in cell DNA integrity disruption was demonstrated in all tested variants: of solution, exposure time and concentration, compared to the control sample. A statistically significant correlation was determined between the level of induced DNA breaks and the concentration of the active solutions and the duration of their activity. A solution of silver nanoparticles stabilized with sodium citrate was shown to have the most harmful effect on bone marrow cells. Silver nitrate demonstrated a level of toxicity similar to these particles. Further studies are necessary to directly compare the genotoxic properties of AgNP produced using the HVAD method and the chemical method under the same conditions.

Abstract
Prevention of infections is a very important issue in treating the burn wounds. The nanosilver dressings have many promising advantages, but absorption of silver ions and its adverse effects to the body were always a question. The aim of this study was to compare Silver serum levels and acute toxic effects of nanosilver on histopathology of organs (lungs, liver, kidney, spleen, and brain) in two types of AgiCoat and Acticoat (nanosilver) dressings on second-degree deep burn in rat. This is an experimental study conducted in our animal laboratory. We divided 24 Sprague-Dawley male rats weighing 300 to 350 randomly into two groups. After anesthesia, a second deep-degree burn was made over dorsal skins of rats by standard method. For group A, Agicoat and, for group B, Acticoat dressings were used. The dressings were changed every 3 days with AgiCoat and Acticoat, respectively. After 14 days, we got blood samples and tissue samples taken from heart, liver, kidneys, spleen, lungs, and brain and a sample from dorsal skin of the rat for histopathological examinations. The results showed that the levels of serum silver in both groups were significantly higher than the standard level (1.22 part per million (PM); AgiCoat, P = .017; Acticoat, P = .000), but there was no significant difference between the groups (P = .551). Examination of the relationship between the level of serum silver and histopathological changes in liver showed that hepatotoxicity of AgiCoat was higher compared with Acticoat and the difference was significant (P = .002). There were no pathological changes in brain, kidneys, spleen, heart, and lungs. Wound healing was faster in Acticoat group. The nanosilver dressings can cause toxicity in liver but not in kidney, brain, spleen, heart, and lungs. Liver pathology and hepatotoxicity were more prominent in AgiCoat group. Wound healing was faster in Acticoat group.

Abstract
Nickel oxide nanoparticles (NiO-NPs) have been used in several consumer goods, reported to demonstrate the hepatotoxic effects in vitro and in vivo test models. Nonetheless the molecular mechanism of hepatotoxicity is still missing. Hence, a toxicogenomic approach integrating microscopic techniques and high-throughput RNA sequencing (RNA-Seq) was applied to reveal hepatotoxicity in human hepatocellular carcinoma cells (HepG2). NiO-NPs induced a concentration dependent (5-100 μg/ml) cytotoxicity, with a No observed effect level (NOEL) of 5 μg/ml. Hypoxia-inducible transcription factor-1α (HIF-1α) and miR-210 microRNA were upregulated at 25 and 100 μg/ml, while significant alteration on transcriptome at mRNA and pathway level was observed at non-toxic level of NiO-NPs treatment. The treated cells also showed activation of glycolysis, glutathione, lysosomes and autophagy pathways by a pathway-driven analysis. Flow cytometric analysis affirmed the elevation in nitric oxide (NO), Ca++ influx, esterase, and disruption of mitochondrial membrane potential (ΔΨm). Cell cycle dysregulation was affirmed by the appearance of 30.5% subG1 apoptotic peak in NiO-NPs (100 μg/ml) treated cells. The molecular responses were consistent with the microscopic observation that NiO-NPs induced subcellular alterations in HepG2 cells. We conclude that hypoxia stress played a pivotal role in NiO-NPs induced hepatoxicity in HepG2 cells. Concentration dependent effects on transcriptomics specify a powerful tool to evaluate the molecular mechanisms of nanoparticle induced cytotoxicity. Overall our study unequivocally affirmed the transcriptomic alterations in human cells, consequently the prevalent usage of NiO-NPs should be given subtle consideration owing to its effects on biological processes.

Acute and subacute dermal toxicity of ethanolic extract of Melastoma malabathricum leaves in Sprague-Dawley rats. Toxicol Res 2020; 36:203-210. [PMID: 32685424 DOI: 10.1007/s43188-019-00013-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Revised: 07/20/2019] [Accepted: 08/22/2019] [Indexed: 11/27/2022] Open
Abstract
Melastoma malabathricum is a well-known herb in Malaysia where it being used in various ways for treatment of different diseases and ailments including skin problems. The study aims to investigate acute and subacute dermal toxicity of ethanolic extract of M. malabathricum leaves following to a single or repeated doses exposure. A total of 30 female Sprague-Dawley rats were grouped into 5 groups (n = 6 per group) for both acute and subacute toxicity study. The duration for each study was determined at 14 days for acute toxicity and 28 days for subacute toxicity. The rats were topically applied with the plant extract at three different doses; 2.5%, 5.0% and 10.0% on the shaved area of dorsal skin. For acute toxicity study, rats in all three groups received single application of the extract on the first day of the experimental period, while rats in subacute toxicity study were topically applied with the extract once daily for 28 days. Throughout the respective 14-day and 28-day study periods, all rats were monitored for any changes in their physical appearance and behavioural patterns that might develop due to toxic effects of the plant. There were no mortality or abnormal physical appearance, and physiological and behavioural changes observed in all rats in both studies. Body weights, kidney and liver weights, and both haematology and serum biochemistry results showed no significant (p > 0.05) differences between all groups in both studies. All of the findings were supported by normal macroscopic and microscopic architectures of liver, kidneys and skin of all rats applied topically with the extract. This study suggests that topical application of M. malabathricum leaf ethanolic extract at 2.5%, 5% and 10% does not induce acute and subacute adverse effects on the skin or systemic toxic reactions in rats.

Abstract
The recent surge in incorporation of metallic and metal oxide nanomaterials into consumer products and their corresponding use in occupational settings have raised concerns over the potential for metals to induce size-specific adverse toxicological effects. Although nano-metals have been shown to induce greater lung injury and inflammation than their larger metal counterparts, their size-related effects on the immune system and allergic disease remain largely unknown. This knowledge gap is particularly concerning since metals are historically recognized as common inducers of allergic contact dermatitis, occupational asthma, and allergic adjuvancy. The investigation into the potential for adverse immune effects following exposure to metal nanomaterials is becoming an area of scientific interest since these characteristically lightweight materials are easily aerosolized and inhaled, and their small size may allow for penetration of the skin, which may promote unique size-specific immune effects with implications for allergic disease. Additionally, alterations in physicochemical properties of metals in the nano-scale greatly influence their interactions with components of biological systems, potentially leading to implications for inducing or exacerbating allergic disease. Although some research has been directed toward addressing these concerns, many aspects of metal nanomaterial-induced immune effects remain unclear. Overall, more scientific knowledge exists in regards to the potential for metal nanomaterials to exacerbate allergic disease than to their potential to induce allergic disease. Furthermore, effects of metal nanomaterial exposure on respiratory allergy have been more thoroughly-characterized than their potential influence on dermal allergy. Current knowledge regarding metal nanomaterials and their potential to induce/exacerbate dermal and respiratory allergy are summarized in this review. In addition, an examination of several remaining knowledge gaps and considerations for future studies is provided.

Abstract
As a new type of antibacterial agent, nanosilver has attracted great attention in biomedical applications. However, the safety of nanosilver to humans and the environment has not been well elucidated. The objective of this study was to investigate the influence of nanosilver on novel effector mechanism of neutrophil extracellular traps (NETs), and its possible molecular mechanisms. In this study, nanosilver (10, 20 and 40 μg/mL) was incubated with neutrophils for 90 min. Then, nanosilver-induced the release of NETs was observed by laser confocal microscopy. Nanosilver-induced NETs release was also quantitatively detected by pico Green®. In addition, the role of NADPH oxidase, extracellular signal-regulated kinase (ERK) and p38 signaling pathways in nanosilver-induced NETs release were detected by the inhibitors and pico Green®. The results indicated that nanosilver significantly activated polymorphonuclear neutrophils (PMN) to release NETs, which was a DNA-based network structure modified with histones (H3) and neutrophil elastase (NE). The inhibitors of NADPH oxidase, ERK and p38 signaling pathways significantly inhibited the formation of nanosilver-induced NETs. Furthermore, nanosilver did not alter the extracellular lactate dehydrogenase (LDH) level of PMN cells. All these results showed that nanosilver significantly induced NETs release, and the potential molecular mechanisms were correlated with reactive oxygen species (ROS) production-dependent on NADPH oxidase, ERK and p38 signaling pathways, which might provide a new perspective on nanosilver-induced excess NETs release related to the host immune damage.

Abstract
Nowadays, nanoproducts have found numerous applications, allowing them to enter the human body in different ways. Skin is a major body organ that acts as the first-line barrier between the internal organs and external environment. Although the inhalation and ingestion of nanoparticles is more dangerous compared with skin exposure, there are noteworthy information gaps in skin exposure to nanoparticles that need much attention. Despite the few reviews in the literature on the cytotoxic effects of nanoparticles, no research has reviewed the clinical side effects of nanoparticles following topical admonition, including skin inflammation, skin cancer and genetic toxicity.

Abstract
Silver nanoparticles (AgNPs) have recently emerged as a powerful agents for disinfection in the poultry industry. AgNPs are capable of epithelial barriers passing from the route of exposure to the vital organs and cells. This study evaluated the effects of AgNPs on organs weights, blood biochemical, hematological, and coagulation parameters, antioxidant enzyme activities, and histopathological changes and silver concentrations of liver and kidney tissues in laying Japanese quails after exposure to the nanoparticles. The layer quails were randomly assigned to 4 groups, consisting of six replicates, three quails each. The treatments included 0, 4, 8, and 12 mg/L of AgNPs in daily drinking water for 30 weeks. AgNPs decreased the relative weight of liver, ileum and large intestine (P < 0.05). Administration of AgNPs elevated plasma fibrinogen while decreased serum aspartate aminotransferase activity (P < 0.05). The antioxidant status of the liver showed that malondialdehyde level, an end product of lipid peroxidation, was higher (P < 0.05) and catalase activity was lower (P < 0.05) in the quails exposed to AgNPs. The accumulation of silver in the liver and kidney tissues were increased in a dose-dependent manner after exposure to AgNPs (P < 0.05). Histopathological findings showed reduced lipid vacuolization of hepatocytes in the 12 mg/L AgNPs treatment. In conclusion, the results indicated that AgNPs administration to drinking water can lead to oxidative stress and liver damage in laying quails which may be a predisposing for liver dysfunction.

Abstract
The field of nanotechnology has grown exponentially during the last few decades, due in part to the use of nanoparticles in many manufacturing processes, as well as their potential as clinical agents for treatment of diseases and for drug delivery. This has created several new avenues by which humans can be exposed to nanoparticles. Unfortunately, investigations assessing the toxicological impacts of nanoparticles (i.e. nanotoxicity), as well as their possible risks to human health and the environment, have not kept pace with the rapid rise in their use. This has created a gap-in-knowledge and a substantial need for more research. Studies are needed to help complete our understanding of the mechanisms of toxicity of nanoparticles, as well as the mechanisms mediating their distribution and accumulation in cells and tissues and their elimination from the body. This review summarizes our knowledge on nanoparticles, including their various applications, routes of exposure, their potential toxicity and risks to human health.

Abstract
Various strategies for combination therapy to overcome current limitations in cancer therapy have been actively investigated. Among them, simultaneous delivery of multiple drugs is a subject of high interest due to anticipated synergistic effect, but there have been difficulties in designing and developing effective nanomaterials for this purpose. In this work, dual-pore coexisting hybrid porous silica nanoparticles are developed through Volmer-Weber growth pathway for efficient co-delivery of gene and anticancer drug. Based on the different pore sizes (2-3 and 40-45 nm) and surface modifications of the core and branch domains, loading and controlled release of gene and drug are achieved by appropriate strategies for each environment. With excellent loading capacity and low cytotoxicity of the present platform, the combinational cancer therapy is successfully demonstrated against human cervical cancer cell line. Through a series of quantitative analyses, the excellent gene-chemo combinational therapeutic efficiency is successfully demonstrated. It is expected that the present nanoparticle will be applicable to various biomedical fields that require co-delivery of small molecule and nucleic acid.

Abstract
Silver nanoparticles (AgNPs) are widely used in health and consumer products that routinely contact skin. However, the biological effects and possible mechanisms of AgNPs on skin remain unclear. Gap junctional intercellular communication (GJIC) plays a critical role in multicellular organisms to maintain tissue homeostasis. The aim of this study is to examine if non-coated AgNPs affect GJIC in human keratinocytes (HaCaT cells), and to identify the possible molecular mechanisms responsible for the effects. GJIC, connexin (Cx)43 protein and mRNA expression, and the effect of siRNA-mediated knockdown of Cx43 on GJIC were assessed. HaCaT cells exposed to non-coated AgNPs at different doses after a 24 hour exposure. To explore further the underlying mechanism, reactive oxygen species and mitogen-activated protein kinase pathway were evaluated after 2, 6, 12 and 24 hours. Our results revealed that non-coated AgNP exposure at subcytotoxic doses increase GJIC partially via Cx43 upregulation. Reactive oxygen species and extracellular signal-regulated kinase and activation of c-Jun N-terminal kinase were involved in the AgNP-induced upregulation of Cx43. This study provides new insight into the potential mechanism of AgNP biological activity.

Abstract
In view of the extensive use of nanoparticles in countless applications, a fast and effective method for assessing their potential adverse effects on the environment and human health is extremely important. At present, in vitro cell-based assays are the standard approach for screening chemicals for cytotoxicity because of their relative simplicity, sensitivity, and cost-effectiveness compared with animal studies. Regrettably, such cell-based viability assays encounter limitations when applied to determining the biological toxicity of nanomaterials, which often interact with assay components and produce unreliable outcomes. We have established a cell-impedance-based, label-free, real-time cell-monitoring platform suitable for use in a variety of mammalian cell lines that displays results as cell index values. In addition to this real-time screening platform, other traditional cytotoxicity assays were employed to validate cytotoxicity assessments. We suggest that the cell impedance measurement approach is effective and better suited to determining the cytotoxicity of nanomaterials for environmental safety screening. © 2016 Wiley Periodicals, Inc.

Abstract
Some reports indicate that the silver released from dermally applied products containing silver nanoparticles (AgNP) (e.g. wound dressings or cosmetics) can penetrate the skin, particularly if damaged. AgNP were also shown to have cytotoxic and genotoxic activity. In the present study percutaneous absorption of AgNP of two different nominal sizes (Ag15nm or Ag45nm by STEM) and surface modification, i.e. citrate or PEG stabilized nanoparticles, in combination with cosmetic ingredients, i.e. aluminum chloride (AlCl3), methyl paraben (MPB), or di-n-butyl phthalate (DBPH) was assessed using in vitro model based on dermatomed pig skin. The inductively coupled plasma mass spectrometry (ICP-MS) measurements after 24h in receptor fluid indicated low, but detectable silver absorption and no statistically significant differences in the penetration between the 4 types of AgNP studied at 47, 470 or 750μg/ml. Similarly, no significant differences were observed for silver penetration when the AgNP were used in combinations with AlCl3 (500μM), MPB (1250μM) or DBPH (35μM). The measured highest amount of Ag that penetrated was 0.45ng/cm2 (0.365-0.974ng/cm2) for PEG stabilized Ag15nm+MPB.

Abstract
Silver is increasingly being used in garments to exploit its antibacterial properties. Information on the presence of silver nanoparticles (AgNPs) in garments and their in vivo penetration across healthy and impaired skin from use is limited. We investigated the presence of AgNPs in a silver containing garment and in the stratum corneum (SC) of healthy subjects (CTRLs) and individuals with atopic dermatitis (AD). Seven CTRLs and seven AD patients wore a silver sleeve (13% Ag w/w) 8 h/day for five days on a forearm and a placebo sleeve on the other forearm. After five days, the layers of the SC were collected by adhesive tapes. The silver particles in the garment and SC were characterized by scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX) and atomic force microscopy (AFM). AFM and SEM revealed the presence of sub-micrometre particles having a broad range of sizes (30-500 nm) on the surface of the garment that were identified as silver. On the SC tapes collected from different depths, aggregates with a wide range of sizes (150 nm-2 μm) and morphologies were found. Most aggregates contained primarily silver, although some also contained chlorine and sulfur. There was no clear difference in the number or size of the aggregates observed in SC between healthy and AD subjects. After use, AgNPs and their aggregates were present in the SC at different depths of both healthy subjects and AD patients. Their micrometre size suggests that aggregation likely occurred in the SC.

Abstract
Aim: Here we evaluated the antibacterial efficacy of soyaethyl morpholinium ethosulfate (SME) micelles as an inherent bactericide against Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). Methodology: The antimicrobial activity was examined by in vitro culture model and murine model of skin infection. Cationic micelles formed by benzalkonium chloride or cetylpyridinium chloride were used for comparison. Results: The minimum inhibitory concentration and minimum bactericidal concentration against S. aureus and MRSA were 1.71–3.42 and 1.71–6.84 μg/ml, respectively. Topical administration of SME micelles significantly decreased the cutaneous infection and MRSA load in mice. The killing of bacteria was caused by direct cell wall/membrane rupture. SME micelles also penetrated into the bacteria to elicit a Fenton reaction and oxidative stress. Conclusion: SME micelles have potential as antimicrobial agents due to their lethal effect against S. aureus and MRSA with a low toxicity to mammalian cells.

Abstract
The resistance of bacteria towards traditional antibiotics currently constitutes one of the most important health care issues with serious negative impacts in practice. Overcoming this issue can be achieved by using antibacterial agents with multimode antibacterial action. Silver nano-particles (AgNPs) are one of the well-known antibacterial substances showing such multimode antibacterial action. Therefore, AgNPs are suitable candidates for use in combinations with traditional antibiotics in order to improve their antibacterial action. In this work, a systematic study quantifying the synergistic effects of antibiotics with different modes of action and different chemical structures in combination with AgNPs against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus was performed. Employing the microdilution method as more suitable and reliable than the disc diffusion method, strong synergistic effects were shown for all tested antibiotics combined with AgNPs at very low concentrations of both antibiotics and AgNPs. No trends were observed for synergistic effects of antibiotics with different modes of action and different chemical structures in combination with AgNPs, indicating non-specific synergistic effects. Moreover, a very low amount of silver is needed for effective antibacterial action of the antibiotics, which represents an important finding for potential medical applications due to the negligible cytotoxic effect of AgNPs towards human cells at these concentration levels.

Abstract
BACKGROUND The nanotechnology boom and the ability to manufacture novel nanomaterials have led to increased production and use of engineered nanoparticles (ENPs). However, the increased use of various ENPs inevitably results in their release in or the contamination of the environment, which poses significant threats to human health. In recent years, extraordinary economic and societal benefits of nanoproducts as well as their potential risks have been observed and widely debated. To estimate whether ENPs are safe from the onset of their manufacturing to their disposal, evaluation of the toxicological effects of ENPs on human exposure, especially on more sensitive and vulnerable sectors of the population (infants and children) is essential. DATA SOURCES Papers were obtained from PubMed, Web of Science, and Google Scholar. Literature search words included: "nanoparticles", "infants", "children", "exposure", "toxicity", and all relevant cross-references. RESULTS A brief overview was conducted to 1) characterize potential exposure routes of ENPs for infants and children; 2) describe the vulnerability and particular needs of infants and children about ENPs exposure; 3) investigate the current knowledge about the potential health hazards of ENPs; and 4) provide suggestions for future research and regulations in ENP applications. CONCLUSIONS As the manufacturing and use of ENPs become more widespread, directed and focused studies are necessary to measure actual exposure levels and to determine adverse health consequences in infants and children.

Abstract
Post-translational modification of histones is linked to a variety of biological processes and disease states. This paper focuses on phosphorylation of histone H3 at serine 10 (p-H3S10), induced by silver nanoparticles (AgNPs) and discusses the usefulness of p-H3S10 as a marker to evaluate the toxicity of AgNPs. Cultured human cells showed remarkable p-H3S10 immediately after treatment with AgNPs but not with Ag microparticles. p-H3S10 lasts up to 24 h and strongly depends upon the cellular uptake of AgNPs. Removal of Ag ions suppressed p-H3S10, while adding an excess of Ag ions augmented p-H3S10. We expected that p-H3S10 requires two events: cellular uptake of AgNPs and continuous release of Ag ions from intracellular AgNPs. AgNPs enhanced the expression of the proto-oncogene c-jun, and p-H3S10 increased in the promoter sites of the gene, indicating that p-H3S10 might indicate a biological reaction related to carcinogenesis. We previously showed that side-scattered light from flow cytometry could be used to measure the uptake potential of nanoparticles [ Suzuki , H. ; Toyooka , T. ; Ibuki , Y. Simple and easy method to evaluate uptake potential of nanoparticles in mammalian cells using a flow cytometric light scatter analysis . Environ. Sci. Technol. 2007 , 41 ( 8 ), 3018 - 3024 ]. Our current findings suggest that p-H3S10 can be used to evaluate the toxicity of AgNPs and Ag ion release in combination with detection of side-scattered light from flow cytometry.

Abstract
BACKGROUND Silver nanoparticles (Ag-NPs) are among the most commonly used nanomaterials and may be exposed to human and ecosystem. Prior in vitro study showed that Ag-NPs compromised neurodevelopment of PC12 cells. This study aims to investigate the effect of prenatal exposure to Ag-NPs on spatial cognition and hippocampal neurodevelopment in rats. METHODS Pregnant rats were exposed by intraperitoneal injection to various solutions during pregnancy, including vehicle (water and glycerol mixture, 1:1 in volume), uncoated Ag-NPs (0.427mg Ag perg rat), polyvinylpyrrolidine (PVP)-coated Ag-NPs (0.407mg Ag perg rat), silver nitrate (0.013mg Ag(+) and 0.007mg NO3(+) per g rat) and sodium nitrate (0.007mg NO3(+) perg rat). Pregnant rats without any injection were used as blank control. Male offspring at postnatal day 35 (PND35) were randomly selected for Morris Water Maze (MWM) test. After the MWM test, the rats were decapitated and hippocampus were collected for analysis of tissue structure, silver content, GAP-43 mRNA and protein expressions. RESULTS For the spatial learning in MWM test, since the third test day, the escape latency of rats in the uncoated Ag-NPs group was significantly higher than those in the other groups. The behaviors of rats were not significantly different among the other groups. The averaged silver content in the hippocampus of rats in the uncoated Ag-NPs group was 17.51μg/g, significantly higher than those in the other groups. The hippocampal structure in rats of the uncoated Ag-NPs group was deformed as compared to those in the other groups. Compared with the rats in blank and vehicle controls, the levels of GAP-43 mRNA and protein in the uncoated Ag-NPs, PVP-coated Ag-NPs, silver nitrate and sodium nitrate groups were all significantly decreased. The levels of GAP-43 mRNA and protein of rats in the uncoated Ag-NPs group was significantly lower than those in the later three groups, while there was no significant difference among the later three groups. CONCLUSIONS Maternal exposure to uncoated Ag-NPs during pregnancy impaired spatial cognition in rat offspring. GAP-43 reduction might be involved in the cognitive impairment. The toxicity was mainly associated with release of silver ion. Coating with PVP reduced the toxicity of Ag-NPs.

Abstract
AbstractThis study aimed to assess levels of silver nanoparticle residues in eggshells and tissues as well as the levels of selected biochemical parameters and oxidative stress indices in chickens hatched from nanosilver disinfected eggs. The samples included 40 Greenleg Partridge chicks allocated into two groups. The experimental group (group D) consisted of chickens hatched from eggs disinfected with a nanosilver preparation prior to incubation, while the control group (group C) included chickens whose eggs were exposed to UV radiation for disinfection. The eggshells and kidney sections obtained from group D chickens showed a significantly higher silver level compared to group C. For the biochemical parameters, only the uric acid content was higher in group D compared to group C. Analysis of the antioxidative stress biomarkers (superoxide dismutase and catalase), showed a significant increase in group D in relation to group C.

Abstract
AbstractThere has been a great deal of attention and research devoted on nanoparticels (NPs) over the last 10 years. From current knowledge in the field of nanotoxicology, it has become evident that the most NPs, if not all are more toxic than bulk materials. The rapid progress and developing has been leading to concerns about the potential risk associated with the use and application of NPs on human health and the environment. Silver nanoparticles (SNPs) are one of the most available and commercially distributed nanomaterials around the world. In order to understand how human health can be affected by SNPs, quantification and detection of SNPs in biological systems have to be conducted in different models. It seems that respiratory and gastrointestinal systems as well as the skin are the major routes of SNPs penetration into the body. Research on SNPs toxicity is mostly conducted in vitro, and the available human and animal data are relatively limited. This review attempts to focus on the characterization and quantification of the potential harmful effects of SNPs on human health.

Abstract
Silver (Ag) and gold nanoparticles (Au NPs) have wide applications. They are increasingly being used in the medical devices, biosensors, cancer cell imaging, and cosmetics. Increased applications of these NPs in the technological advances have also led to the risk of exposure to these particles. This study investigated the toxic effects of Ag and Au NPs (1 μM and 2 μM, oral) on mouse erythrocytes and tissues after 14 consecutive days’ exposure. Our results demonstrate significant increase in reactive oxygen species (ROS) and depletion of antioxidant enzyme status in erythrocytes and tissues. Hepatic and renal toxicity was evident from liver and kidney function tests. Inflammatory markers, interleukin-6 and nitric oxide synthase increased in plasma on administration following exposure to these NPs at both the doses. A more pronounced increase was noted in kidney metallothionein (MT) compared to liver MT on exposure to these NPs. Toxic potential of these NPs was further confirmed by increased 8-hydroxy-2′-deoxyguanosine levels in urine, a biomarker of DNA damage. Among the two NPs, Ag NP was more toxic at 2 μM dose compared to lower dose of 1 μM. The study suggests oxidative stress as the major mechanism responsible for the toxic manifestations induced by Ag and Au NPs.

Abstract
Increased application of silver nanoparticles (AgNPs) has raised concerns on their potential adverse effects on human health. However, the precise toxicological mechanisms are not known in detail. The current study hypothesized that AgNPs induced glycosaminoglycan accumulation in the basement membrane that associated with the up-regulation of its component hyaluronic acid, known as a hydrophilic molecule of binding and retaining water, and caused toxicities in the kidney and cochlea. Rats administered AgNPs through either intravenous or intratympanic injection were observed at different time points after exposure. The concentrations of creatinine and urea in the serum were elevated remarkably, and proteins leaked into the urine were increased. A significant hearing loss over a broad range of frequencies was indicated. AgNP exposure induced glycosaminoglycan accumulation and hyaluronic acid up-regulation in the basement membrane. Abundant apoptotic cell death was demonstrated in the AgNP-exposed organs. Our results suggested that glycosaminoglycan accumulation associated with the up-regulation of hyaluronic acid was involved in the toxicities of kidney and cochlea caused by AgNPs.

Abstract
BACKGROUND Factors that influence exposure to silver particles from the use of textiles are not well understood. OBJECTIVES The aim of this study was to evaluate the influence of product treatment and physiological factors on silver release from two textiles. METHODS Atomic and absorbance spectroscopy, electron microscopy, and dynamic light scattering (DLS) were applied to characterize the chemical and physical properties of the textiles and evaluate silver release in artificial sweat and saliva under varying physiological conditions. One textile had silver incorporated into fiber threads (masterbatch process) and the other had silver nanoparticles coated on fiber surfaces (finishing process). RESULTS Several complementary and confirmatory analytical techniques (spectroscopy, microscopy, etc.) were required to properly assess silver release. Silver released into artificial sweat or saliva was primarily in ionic form. In a simulated "use" and laundering experiment, the total cumulative amount of silver ion released was greater for the finishing process textile (0·51±0·04%) than the masterbatch process textile (0·21±0·01%); P<0·01. CONCLUSIONS We found that the process (masterbatch vs finishing) used to treat textile fibers was a more influential exposure factor than physiological properties of artificial sweat or saliva.

Abstract
INTRODUCTION Cutaneous and mucocutaneous leishmaniasis are major tropical skin diseases. Topical treatment is currently limited to the least severe forms of cutaneous leishmaniasis (CL) without risk of dissemination. It is also recommended in combination with systemic therapy for more severe forms. Progresses in this modality of treatment are hindered by the heterogeneity of the disease and shortcomings in the clinical trials. AREAS COVERED This review overlooks three major modalities of topical therapies in use or under investigation against CL: chemotherapy, photodynamic therapy and immunotherapy; either with older compounds such as paramomycin or more recent nitric oxide donors, antimicrobial peptides or silver derivatives. The advantages and limitations of their administration with newer formulation strategies such as nanoparticles (NPs) are discussed. EXPERT OPINION The efficacy of a topical treatment against CL depends not only on the intrinsic antileishmanial activity of the drug but also on the amount of drug available in the dermis. NPs as sustained release systems and permeation enhancers could favour the creation of a drug reservoir in the dermis. Additionally, certain NPs have immunomodulatory properties or wound healing capabilities of benefit in CL treatment. Pending task is the selective delivery of active compounds to intracellular amastigotes, because even small NPs are unable to penetrate deeply into the skin to encounter infected macrophages (except in ulcerative lesions).

Abstract
This study compares the disinfection performance of ceramic water filters impregnated with two antibacterial compounds: silver nanoparticles and a polymer based quaternary amine functiaonalized silsesquioxane (poly(trihydroxysilyl) propyldimethyloctadecyl ammonium chloride (TPA)). This study evaluated these compounds using ceramic disks manufactures with clay obtained from a ceramic filter factory located in San Mateo Ixtatan, Guatemala. Instead of using full size ceramic water filters, manufactured 6.5 cm diameter ceramic water filter disks were used. Results showed that TPA can achieve a log bacterial reduction value of 10 while silver nanoparticles reached up to 2 log reduction using a initial concentration of bacteria of 10(10)-10(11)CFU/ml. Similarly, bacterial transport demonstrated that ceramic filter disks painted with TPA achieved a bacterial log reduction value of 6.24, which is about 2 log higher than the values obtained for disks painted with silver nanoparticles (bacterial log reduction value: 4.42). The release of both disinfectants from the ceramic materials to the treated water was determined measuring the effluent concentrations in each test performed. Regarding TPA, about 3% of the total mass applied to the ceramic disks was released in the effluent over 300 min, which is slightly lower than the release percentage for silver nanoparticles (4%). This study showed that TPA provides a comparable disinfection performance than silver nanoparticles in ceramic water filter. Another advantage of using TPA is the cost as the price of TPA is considerable lower than silver nanoparticles. In spite of the use of TPA in several medical related products, there is only partial information regarding the health risk associated with the ingestion of this compound. Additional long-term toxicological information for TPA should be evaluated before its future application in ceramic water filters.

Abstract
BACKGROUND Many in vitro studies have revealed that the interference of dye molecules in traditional nanoparticle cytotoxicity assays results in controversial conclusions. The aim of this study is to establish an extensive and systematic method for evaluating biological effects of gold nanoparticles in mammalian cell lines. METHODS We establish the cell-impedance measurement system, a label-free, real-time cell monitoring platform that measures electrical impedance, displaying results as cell index values, in a variety of mammalian cell lines. Cytotoxic effects of gold nanoparticles are also evaluated with traditional in vitro assays. RESULTS Among the six cell lines, gold nanoparticles induce a dose-dependent suppression of cell growth with different levels of severity and the suppressive effect of gold nanoparticles was indirectly associated with their sizes and cellular uptake. Mechanistic studies revealed that the action of gold nanoparticles is mediated by apoptosis induction or cell cycle delay, depending on cell type and cellular context. Although redox signaling is often linked to the toxicity of nanoparticles, in this study, we found that gold nanoparticle-mediated reactive oxygen species generation was not sustained to notably modulate proteins involved in antioxidative defense system. CONCLUSION The cell-impedance measurement system, a dye-free, real-time screening platform, provides a reliable analysis for monitoring gold nanoparticle cytotoxicity in a variety of mammalian cell lines. Furthermore, gold nanoparticles induce cellular signaling and several sets of gene expression to modulate cellular physical processes. GENERAL SIGNIFICANCE The systematic approach, such as cell-impedance measurement, analyzing the toxicology of nanomaterials offers convincing evidence of the cytotoxicity of gold nanomaterials.

State of the art in human risk assessment of silver compounds in consumer products: a conference report on silver and nanosilver held at the BfR in 2012. Arch Toxicol 2013; 87:2249-62.

Abstract
In light of the broad spectrum of products containing nanosilver, the harmfulness of nanosilver to human health and the environment was intensively discussed at a conference held in February 2012 at the BfR. The conference agenda covered the aspects of analytics of nanosilver materials, human exposure and toxicology as well as effects on microorganisms and the environment. The discussion recovered major gaps related to commonly agreed guidelines for sample preparation and central analytical techniques. In particular, the characterization of the nanoparticles in complex matrices was regarded as a challenge which might become a pitfall for further innovation and application. Historical and anecdotal records of colloidal silver have been sometimes taken as empirical proof for the general low toxicity of nanosilver. Yet as reported herein, a growing number of animal studies following modern performance standards of toxicity testing have been carried out recently revealing well-characterized adverse effects on different routes of exposure in addition to argyria. Furthermore, recent approaches in exposure assessment were reported. However, consumer exposure scenarios are only starting to be developed and reliable exposure data are still rare. It was further widely agreed on the workshop that the use of silver may lead to the selection of silver resistant bacteria. With respect to its environmental behavior, it was suggested that nanosilver released to wastewater may have negligible ecotoxicological effects. Finally, the presentations and discussion on risk assessment and regulation of nanosilver applications gave insights into different approaches of risk assessment of nanomaterials to be performed under the various regulatory frameworks.

Abstract
Silver nanoparticles (Ag NPs) have been widely used as new potent antimicrobial agents in cosmetic and hygienic products. Present study compares the tissue levels of Ag NPs in different organs of Guiana Pigs quantitatively after dermal application and analysis the morphological changes and pathological abnormalities on the basis of the Ag NPs tissue levels. Before toxicological assessments,the size of colloidal nanosilver was recorded by X-Ray Diffraction and Transmission Electron Microscope tests and the sizes of samples were recorded in sizes less than 100 nm. For toxicological evaluation, male guinea pigs were exposed to three concentrations of Ag NPs (100, 1000 and 10000 ppm) according to acute pretests for further assessments in subchronic model in a period of 13 weeks . A close correlation between dermal exposure and tissue levels of Ag NPs was found (p < 0.05) and tissue uptakes happened in dose dependent manner with the following ranking: ki dney>muscle>bone>skin>liver>heart >spleen. In histopathological studies, severe proximal convoluted tubule degeneration and distal convoluted tubule were seen in the kidneys of the middle and high-dose animals. Separated lines and marrow space narrow were determined as two major signs of bone toxicities which observed in three different dose levels of Ag NPs. Increased dermal dose of Ag NPs caused cardiocyte deformity, congestion and inflammation. The three different Ag NPs concentration gave comparable results for several endpoints measured in heart, bone and kidney, but differed in tissue concentrations and the extent of histopathological changes. It seems that Ag ions could be detected in different organs after dermal exposure ,which has the potential to provide target organ toxicities in a time and dose dependent manner.
