Abstract
Diabetic encephalopathy (DE) is one of the major chronic complications of diabetes mellitus. This study aims to investigate the inhibitory effect of berberine (BBR) on the damage of PC12 cells induced by high glucose (HG). Differentiated PC12 cells were treated with different concentrations of glucose/BBR. The cell morphology, cell viability, lactate dehydrogenase (LDH) activity, apoptosis, oxidative stress (OS), mitochondrial structure, mitochondrial membrane potential (MMP), mitochondrial complex I-V activity, and adenosine triphosphate (ATP) levels were evaluated. The mRNA and protein levels of the Keap1/Nrf2/ARE pathway-related genes were assessed by RT-qPCR and Western blot. High-dose BBR and HG jointly treated-PC12 cells were treated with Nrf2-specific inhibitor ML385 to further verify whether Nrf2 was the target of BBR. The results showed that BBR inhibited cell damage, OS, and mitochondrial dysfunction induced by HG. The inhibitory effect of high BBR was more significant. The Keap1/Nrf2/ARE pathway was inhibited in PC12 cells induced by HG. BBR could activate the Keap1/Nrf2/ARE pathway, thus up-regulating the expression levels of antioxidant enzymes. ML385 antagonized the ameliorating effect of BBR on OS and mitochondrial dysfunction. The conclusion is that BBR can activate the Keap1/Nrf2/ARE pathway, upregulate the expression patterns of antioxidant enzymes, and reduce cell damage, OS, and mitochondrial dysfunction of PC12 cells induced by HG.

Abstract
Foodborne infections are an important global health problem due to their high prevalence and potential for severe complications. Bacterial contamination of meat during processing at the enterprise can be a source of foodborne infections. Polymeric coatings with antibacterial properties can be applied to prevent bacterial contamination. A composite coating based on fluoroplast and Ag2O NPs can serve as such a coating. In present study, we, for the first time, created a composite coating based on fluoroplast and Ag2O NPs. Using laser ablation in water, we obtained spherical Ag2O NPs with an average size of 45 nm and a ζ-potential of -32 mV. The resulting Ag2O NPs at concentrations of 0.001-0.1% were transferred into acetone and mixed with a fluoroplast-based varnish. The developed coating made it possible to completely eliminate damage to a Teflon cutting board. The fluoroplast/Ag2O NP coating was free of defects and inhomogeneities at the nano level. The fluoroplast/Ag2O NP composite increased the production of ROS (H2O2, OH radical), 8-oxogualnine in DNA in vitro, and long-lived active forms of proteins. The effect depended on the mass fraction of the added Ag2O NPs. The 0.01-0.1% fluoroplast/NP Ag2O coating exhibited excellent bacteriostatic and bactericidal properties against both Gram-positive and Gram-negative bacteria but did not affect the viability of eukaryotic cells. The developed PTFE/NP Ag2O 0.01-0.1% coating can be used to protect cutting boards from bacterial contamination in the meat processing industry.

The Development of New Nanocomposite Polytetrafluoroethylene/Fe 2O 3 NPs to Prevent Bacterial Contamination in Meat Industry. Polymers (Basel) 2022; 14:polym14224880. [PMID: 36433009 PMCID: PMC9695638 DOI: 10.3390/polym14224880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Revised: 11/08/2022] [Accepted: 11/10/2022] [Indexed: 11/15/2022] Open
Abstract
The bacterial contamination of cutting boards and other equipment in the meat processing industry is one of the key reasons for reducing the shelf life and consumer properties of products. There are two ways to solve this problem. The first option is to create coatings with increased strength in order to prevent the formation of micro damages that are favorable for bacterial growth. The second possibility is to create materials with antimicrobial properties. The use of polytetrafluoroethylene (PTFE) coatings with the addition of metal oxide nanoparticles will allow to the achieving of both strength and bacteriostatic effects at the same time. In the present study, a new coating based on PTFE and Fe2O3 nanoparticles was developed. Fe2O3 nanoparticles were synthesized by laser ablation in water and transferred into acetone using the developed procedures. An acetone-based colloidal solution was mixed with a PTFE-based varnish. Composites with concentrations of Fe2O3 nanoparticles from 0.001-0.1% were synthesized. We studied the effect of the obtained material on the generation of ROS (hydrogen peroxide and hydroxyl radicals), 8-oxoguanine, and long-lived active forms of proteins. It was found that PTFE did not affect the generation of all the studied compounds, and the addition of Fe2O3 nanoparticles increased the generation of H2O2 and hydroxyl radicals by up to 6 and 7 times, respectively. The generation of 8-oxoguanine and long-lived reactive protein species in the presence of PTFE/Fe2O3 NPs at 0.1% increased by 2 and 3 times, respectively. The bacteriostatic and cytotoxic effects of the developed material were studied. PTFE with the addition of Fe2O3 nanoparticles, at a concentration of 0.001% or more, inhibited the growth of E. coli by 2-5 times compared to the control or PTFE without NPs. At the same time, PTFE, even with the addition of 0.1% Fe2O3 nanoparticles, did not significantly impact the survival of eukaryotic cells. It was assumed that the resulting composite material could be used to cover cutting boards and other polymeric surfaces in the meat processing industry.
