Summary: The presence of Bisphenol A (BPA), Bisphenol A Diglycidyl Ether (BADGE), and their derivatives in seventy-nine samples of food products available in Turkish stores was determined using UPLC-MS/MS. BPA was the most detected migrant with 56.97%, followed by BADGE derivatives. Fish products had the highest level of BPA with 0.102 mg/kg, although only three fish samples exceeded the SML for BPA. BADGE derivatives, BADGE·2H(2)O and CdB, were present in 57 and 52 samples, with concentrations ranging between 0-0.354 and 0-1.056 mg/kg, respectively.

Summary: The exposure to bisphenols and their derivatives in 33 fish products in Turkey was assessed using high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). The study found that the concentrations of BADGE and hydrolyzed products were below the specific migration limit (SML) value set by the European Union, while chlorinated derivatives of BADGE had a lower detection rate compared to hydrolyzed ones.

Summary: BDDE substituted HA hydrogels are widely used in the biomedical field. The characterization of their fine structure is crucial for quality assurance, and this study developed LC-MS methods for accurate determination and in-depth characterization. Previously unknown structures were detected in cross-linked fragments, which contained a GlcNAc residue modified at OH1. This special sugar unit may serve as a signature for distinguishing subtle batch-to-batch variations.

Summary: This study reported the preparation and systematic investigation of cross-linked polyurethane-epoxy (PU-EP) polymer systems. The PU-EP polymers were synthesized by reacting NCO-terminated PU prepolymers with diglycidyl ether of bisphenol A (DGEBA)-amine cooligomers. The addition of furfurylamine (FA) or ethanolamine (EA) resulted in the oligomerization of DGEBA and the formation of DGEBA-amine cooligomers. The cross-linking was achieved by adding the DGEBA-amine cooligomer to the PU prepolymers, forming urethane bonds as netpoints. The presence of furfurylamine allowed for the formation of additional thermoreversible bonds, leading to shape memory behavior in the PU-EP networks.

Summary: In this study, a gamma relaxation in a series of epoxy resins based on DGEBA is measured and analyzed. By altering the network architecture and studying the temperature dependence of the loss peak frequency, a new interpretation of the relaxation process is proposed. It is found that the relaxation process can be best described as a thermally assisted tunnelling displacement of a proton. The proposed approach provides a new method for understanding gamma relaxations in these materials.

Summary: The curing behavior and physical properties of an epoxy-based system for an injectable wellbore sealant were investigated. The material behavior is dependent on curing temperature and comonomer content, with increasing temperature or DGEBA content affecting the curing rate, pre-curing solution viscosity, and post-curing glass transition temperature.

Summary: The epoxy resin diglycidyl ether of Bisphenol A (BADGE n = 0) was cured with a new synthesized hardener (2-adamantylethanamine) and characterized by DSC, showing higher enthalpy of reaction and glass transition temperature values. Activation energies were determined for autocatalytic and then-order mechanisms, with the latter being lower due to steric effects of the adamantyl group hindering ring opening during curing. Selecting the appropriate cross-linking agent can increase T(g) and reduce activation energy, beneficial for certain industrial applications.

Summary: The polymeric coating of forty-eight cans was assessed and a component called CdB was found. The cans were tested using an infrared spectrometer and the food samples were analyzed using liquid chromatography with fluorescence detection. The concentration of CdB was found to be 2623 mu g/kg, but it did not exceed the tolerable daily intake for chemical compounds. Additionally, 18 epoxy oligomers were tentatively identified in the food extracts, with BADGE.H2O.BuEtOH being the most common derivative.

Summary: The antibacterial activities of thyme essential oil nanoemulsions prepared by ultrasonication and high-pressure homogenization were evaluated, with superior bacteriostatic and bactericidal effects observed for the ultrasonicated samples. The underlying antibacterial mechanisms targeting cell membranes of both Gram-negative and Gram-positive bacteria were investigated, revealing membrane disintegrations and dysfunctions associated with fatty acid composition modifications upon exposure to the nanoemulsions. These results provide insights into the mode of action of the nanoemulsions, laying a critical theoretical basis for their future application in food matrix.

Summary: In this study, chitosan films were improved by incorporating nanofillers to enhance their mechanical properties, barriers, and antibacterial properties. The addition of lignin nanoparticles improved UV blocking property, while the inclusion of acylated soy protein isolate nanogel enhanced the sustained antibacterial property. The optimal composite film showed increased tensile strength and decreased oxygen barrier property compared to pure chitosan film, exhibiting higher antibacterial activity. However, the incorporation of nanofillers slightly reduced light transmission and increased surface roughness of the films.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
