Abstract
BACKGROUND Stress-related diseases are on the rise and stress is one of the common factors that lead to ulcer. Stress-induced mucosal bleeding is a serious complication observed in many critically ill patients. Due to the harmful side effects of proton pump inhibitors, natural and active alternative treatment methods for peptic ulcer treatment that are safe in terms of side effects are an urgent need for human health. We aimed to investigate the dose-dependent protective effects of Lactobacillus rhamnosus GG (LGG) against stress ulcers induced by cold restraint stress in rats. This study was performed in a total of 42 rats, in control group (C), stress group (S), pantoprazol (20 mg kg-1 day-1) group (P), LGG (3 × 108 cfu mL-1 day-1) + stress group (M1), LGG (15 × 108 mL-1 day-1) + stress group (M5) and LGG (30 × 108 mL-1 day-1) + stress group (M10) (each n = 7). Ulceration areas (mm2) were determined quantitatively with ImageJ software. Glucocorticoid, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels were determined by ELISA and malondialdehyde levels were determined by spectrophotometric measurement. Histopathological examinations were performed in gastric tissue. RESULTS Therapeutic dose of LGG increased CAT, SOD and GPx levels; prevented excessive activation of the hypothalamic-pituitary-adrenal axis; reduced ulceration and bleeding in the gastric mucosal layer; and provided stabilization of mast cells. CONCLUSIONS We can suggest that LGG may be beneficial for reducing the negative effects of stress on the body, for protecting against ulcer disease and for reducing or preventing the risk of stress-induced gastrointestinal bleeding in patients staying in intensive care units. © 2024 The Author(s).

Abstract
The food additive E171 (titanium dioxide, TiO2), is widely used in foods, pharmaceuticals and cosmetics. It is a fine white powder, with at least one third of its particles sized in the nanoparticulate (˂100 nm range, TiO2 NPs). The use of E171 is controversial as its relevant risk assessment has never been satisfactorily accomplished. In vitro and in vivo studies have shown dose-dependent toxicity in various organs including the liver. TiO2 NPs have been shown to induce inflammation, cell death and structural and functional changes within the liver. The toxicity of TiO2 NPs in experimental models varies between organs and according to their physiochemical characteristics and parameters such as dosage and route of administration. Among these factors, ingestion is the most significant exposure route, and the liver is a key target organ. The aim of this review is to highlight the reported adverse effects of orally administered TiO2 NPs on the liver and to discuss the controversial state of its toxicity.

ENVIRONMENTAL TOXICOLOGY 2024; 39:2681-2691.

Abstract
It is well known that polystyrene nanoplastics (PS-NaP) and nano-titanium dioxide (TiO2 NPs) are frequently co-appeared in daily life and can cause liver injury when they accumulate in the liver. Nonetheless, the combined toxicological impacts and potential molecular mechanisms of PS-NaP and TiO2 NPs in the hepatic system have not been revealed. Thus, we conducted experiments on C57BL/6 mice exposed to PS-NaP or/and TiO2 NPs for 4 weeks. The findings suggested that PS-NaP and TiO2 NPs co-exposed significantly altered the hepatic function parameters, levels of antioxidant-related enzymes and genes expression of Keap-1/Nrf2/ARE signaling pathway, as well as significantly increased the hepatic Ti contents, aggravated hepatic pathological and oxidative stress (OS) damage compared with individual exposure to PS-NaP or TiO2 NPs. Using N-Acetyl-L-cysteine (NAC), an OS inhibitor, we further demonstrated that OS played a pivotal role in coexposure-induced liver injury. NAC reduced the levels of OS in mice, which mitigated co-exposure-induced liver injury. Taken together, we proposed that PS-NaP and TiO2 NPs co-exposed activated the Keap-1, then inhibited the recognition of Nrf2 and ARE, consequently exacerbated liver injury. These findings shed light on the co-toxicity and potential mechanism of nanoplastics and nanoparticles, which informed the risk assessment of human exposure to environmental pollutants.

Postbiotic Preparation of Lacticaseibacillus rhamnosus GG against Diarrhea and Oxidative Stress Induced by Spike Protein of SARS-CoV-2 in Human Enterocytes. Antioxidants (Basel) 2023; 12:1878. [PMID: 37891957 PMCID: PMC10604595 DOI: 10.3390/antiox12101878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 10/08/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
The Spike protein of SARS-CoV-2 acts as an enterotoxin able to induce chloride secretion and production of reactive oxygen species (ROS), involved in diarrhea pathogenesis. L. rhamnosus GG (LGG) is recommended in pediatric acute gastroenteritis guidelines as a therapy independent of infectious etiology. We tested a postbiotic preparation of LGG (mLGG) in an in vitro model of COVID-associated diarrhea. Caco-2 cell monolayers mounted in Ussing chambers were exposed to Spike protein, and electrical parameters of secretory effect (Isc and TEER) were recorded in the Ussing chambers system. Oxidative stress was analyzed by measuring ROS production (DCFH-DA), GSH levels (DNTB), and lipid peroxidation (TBARS). Experiments were repeated after mLGG pretreatment of cells. The Isc increase induced by Spike was consistent with the secretory diarrhea pattern, which was dependent on oxidative stress defined by a 2-fold increase in ROS production and lipid peroxidation and variation in glutathione levels. mLGG pretreatment significantly reduced the secretory effect (p = 0.002) and oxidative stress, namely ROS (p < 0.001), lipid peroxidation (p < 0.001), and glutathione level changes (p < 0.001). LGG counteracts Spike-induced diarrhea by inhibiting the enterotoxic effect and oxidative stress. The LGG efficacy in the form of a postbiotic depends on metabolites secreted in the medium with antioxidant properties similar to NAC. Because SARS-CoV-2 is an enteric pathogen, the efficacy of LGG independent of etiology in the treatment of acute gastroenteritis is confirmed by our data.

Abstract
Most of the literature has focused on titanium dioxide (TiO2) nanoparticles (NPs) toxicity, showing the importance of oxidative stress, mitochondrial dysfunction, and cell death in TiO2-induced toxicity. For this purpose, in the current study, we investigated the protective role of antioxidant and mitochondrial/lysosomal protective agents to minimize TiO2 NPs-induced toxicity in human lymphocytes. Human lymphocytes were obtained from heathy individuals and treated with different concentrations (80, 160, and 320 µg/mL) of TiO2 NPs, and then human lymphocytes preincubated with butylated hydroxytoluene (BHT), cyclosporin A (CsA), and chloroquine separately were exposed to TiO2 NPs for 6 h. In all the above-mentioned treated groups, adverse parameters such as cytotoxicity, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), lysosomal membrane destabilization, the levels of malondialdehyde (MDA), and glutathione (GSH) were measured. The results showed that TiO2 nanoparticles induced cytotoxicity through ROS formation, MMP collapse, lysosomal damages, depletion of GSH, and lipid peroxidation. However, BHT as an antioxidant, CsA as a mitochondrial permeability transition (MPT) pore sealing agent, and chloroquine as a lysosomotropic agent, significantly inhibited all the TiO2 NPs-induced cellular and organelle toxicities. Thus, it seems that antioxidant and mitochondrial/lysosomal protective agents are promising preventive strategies against TiO2 NPs-induced toxicity.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently regarded as the twenty-first century's plague accounting for coronavirus disease 2019 (COVID-19). Besides its reported symptoms affecting the respiratory tract, it was found to alter several metabolic pathways inside the body. Nanoparticles proved to combat viral infections including COVID-19 to demonstrate great success in developing vaccines based on mRNA technology. However, various types of nanoparticles can affect the host metabolome. Considering the increasing proportion of nano-based vaccines, this review compiles and analyses how COVID-19 and nanoparticles affect lipids, amino acids, and carbohydrates metabolism. A search was conducted on PubMed, ScienceDirect, Web of Science for available information on the interrelationship between metabolomics and immunity in the context of SARS-CoV-2 infection and the effect of nanoparticles on metabolite levels. It was clear that SARS-CoV-2 disrupted several pathways to ensure a sufficient supply of its building blocks to facilitate its replication. Such information can help in developing treatment strategies against viral infections and COVID-19 based on interventions that overcome these metabolic changes. Furthermore, it showed that even drug-free nanoparticles can exert an influence on biological systems as evidenced by metabolomics.

Abstract
This study proposed to demonstrate the neuroprotective effects of heat-killed Levilactobacillus brevis KU15152. Heat-killed L. brevis KU15152 showed antioxidant activity similar to that of Lacticaseibacillus rhamnosus GG, in terms of radical scavenging activity. To evaluate the neuroprotective effects, conditioned medium (CM) obtained by incubating heat-killed bacteria in intestinal cells (HT-29) was used through gut-brain axis. CM from L. brevis KU15152 protected neuroblastoma cells (SH-SY5Y) against H2O2-induced oxidative stress. Pretreatment with CM significantly alleviated the morphological changes induced by H2O2. Heat-killed L. brevis KU15152 showed an increased brain-derived neurotrophic factor (BDNF) expression in HT-29 cells. L. brevis KU15152-CM remarkably downregulated the Bax/Bcl-2 ratio, while upregulating the expression of BDNF and tyrosine hydroxylase (TH) in SH-SY5Y cells. Furthermore, L. brevis KU15152-CM reduced caspase-3 activity following H2O2 treatment. In conclusion, L. brevis KU15152 can be potentially used as food materials to avoid neurodegenerative diseases.

Abstract
Currently, the widespread use of TiO2 and ZrO2 nanoparticles (NPs) in various industries poses a risk in terms of their potential toxicity. A number of experimental studies provide evidence of the toxic effect of TiO2 and ZrO2 NPs on biological objects. In order to supplement the level of knowledge and assess the risks of toxicity and danger of TiO2 and ZrO2 NPs, we decided to conduct a comprehensive experiment to study the embryonic toxicity of TiO2 and ZrO2 NPs in pregnant rats. For the experiment, mongrel white rats during pregnancy received aqueous dispersions of powders of TiO2 and ZrO2 NPs at a dose of 100 mg/kg/day. To characterize the effect of TiO2 and ZrO2 NPs on females and the postnatal ontogenesis of offspring, a complex of physiological and biochemical research methods was used. The results of the experiment showed that TiO2 NPs as ZrO2 NPs (100 mg/kg per os) cause few shifts of similar orientation in the maternal body. Neither TiO2 NPs nor ZrO2 NPs have an embryonic and teratogenic effect on the offspring in utero, but both modify its postnatal development.

Abstract
The imbalance of intestinal microbiota and inflammatory response is crucial in the development of lung injury induced by PM2.5. In recent years, probiotics have attracted great attention for their health benefits in inflammatory diseases and regulating intestinal balance, but their intricate mechanisms need further experiments to elucidate. In our research, a rat lung damage model induced by PM2.5 exposure in real environment was established to explore the protective properties of probiotics on PM2.5 exposure injury and its related mechanism. The results indicated that compared with the AF control group, rats in the PM2.5 group gained weight slowly, ate less and had yellow hair. The results of pathological and immunohistochemical examinations showed that the inflammatory infiltration of lung tissue was alleviated after probiotic treatment. The Lung function results also showed the improvement effects of probiotics administration. In addition, probiotics could promote the balance of Th17 and Treg cells, inhibit cytokines expression (TNF-α, IL-6, IL-1β, IL-17A), and increase the concentration of anti-inflammatory factors (IL-10, TGF-β). In addition, 16 S rRNA sequence analysis showed that probiotic treatment could reduce microbiota abundance and diversity, increase the abundance of possible beneficial bacteria, and decrease the abundance of bacteria associated with inflammation. In general, probiotic intervention was found to have preventive effects on the occurrence of PM2.5 induced pathological injury, and the mechanism was associate with to the inhibition of inflammatory response, regulation of Th17/Treg balance and maintenance of intestinal internal environment stability.

Abstract
Acute liver injury (ALI) has a high mortality rate of approximately 20–40%, and it is imperative to find complementary and alternative drugs for treating ALI. A carbon tetrachloride (CCl4)-induced ALI mouse model was established to explore whether dietary intervention can alleviate ALI in mice. Intestinal flora, intestinal integrity, biomarkers of hepatic function, systemic inflammation, autophagy, and apoptosis signals were detected through a real-time PCR, hematoxylin-eosin staining, 16S rRNA gene sequencing, and so on. The results showed that Lactiplantibacillus plantarum 1201 had a strongly antioxidant ability, and galactooligosaccharide (GOS) could boost its growth. Based on these findings, the combination of L. plantarum 1201 and GOS, the synbiotic, was applied to prevent CCl4-induced ALI in mice. The current research proved that GOS promoted the intestinal colonization of L. plantarum 1201, and the synbiotic improved the antioxidant capacity of the host, regulated the intestinal flora, repaired the intestinal barrier, inhibited the activation of the MAPK/NF-κB pathway, and then inhibited the apoptosis and autophagy pathways, relieving inflammation and liver oxidation; thereby, the ALI of mice was alleviated. These results suggest that synbiotics may become a new research direction for liver-protecting drugs.

Abstract
A huge number of titanium dioxide nanoparticles (TiO2 NPs) exist in confectionery foods, which is a high-risk factor for development of diet-induced metabolism syndrome (MetS). In this study, we built a high fructose drinking-induced MetS mouse model, and oral intake of 20 mg/kg TiO2 NPs was administered for 8 weeks. Significant pathological changes and inflammatory factors of overproduction were detected in the liver and colon. The 16S rDNA sequencing analysis results indicated that TiO2 NPs evidently and further perturbed the gut microbiota diversity, compositions, and KEGG pathways in MetS mice. Fecal microbiota transplant experiment proved that TiO2 NPs-altered gut microbiota drives liver and colon inflammation damage. More importantly, oral supplementation of Lactobacillus rhamnosus GG (LGG) ameliorated not only the TiO2 NPs-induced inflammation but also the fructose-caused metabolic abnormality. LGG recovered the gut dysbiosis and decreased the abundance of inflammation-related bacteria (Desulfovibrionaceae, Clostridia, and Proteobacteria), thereby protecting against TiO2 NPs-induced severe inflammation damage. Our study suggests the necessity of assessing the toxic effects of foodborne nanoparticles on the chronic disease population and potential usefulness of probiotics as prophylactic and therapeutic.
