The article contains new information on the current problem of the influence of endo- and exopathogenic factors on the structure of the digestive system. The purpose of the study was to establish the structural features of the interlobular bile ducts under the conditions of six weeks of exposure to nalbuphine in the experiment. The study was based on 30 white laboratory rats of male reproductive age. Histological sections of the liver were stained with hematoxylin and eosin according to conventional methods. The «Aver Media» computer system was used to photograph the micropreparations. The computer program ImageJ was used to measure the diameter of the lumen and the wall thickness of the interlobular bile duct. «Excel» and «Statistica» 6.0 software were used for statistical processing of the obtained digital data. The results of the study show that against the background of nalbuphine administration for six weeks there are morphological changes in the interlobular bile ducts of experimental animals, manifested by destructuring of the interlobular bile ducts, loss of their proper shape, expansion and unevenness of their lumens, deformation and thickening of the interstitial walls in 2-3 times, disorganization of cholangiocytes, thinning of the cell layer due to detachment of cholangiocytes, polymorphism of their nuclei, stratification, fragmentation of the lamina propria of the interlobular bile ducts, periductal edema, dilatation of interlobular portal tracts, "varicose" veins of the interlobular portal tracts, pronounced smooth muscle hyperplasia of the interlobular arteries, the presence of perivascular lymphocytic infiltrates. The data of the study can be used in practical medicine in the diagnosis and treatment of pathology of the bile ducts due to long-term use of opioids.

This study highlights the thermal characterization of ABS-Graphene blended three dimensional (3D) printed functional prototypes by fused deposition modeling (FDM) process. These functional prototypes have some applications as electro-chemical energy storage devices (EESD). Initially, the suitability of ABS-Graphene composite material for FDM applications has been examined by melt flow index (MFI) test. After establishing MFI, the feedstock filament for FDM has been prepared by an extrusion process. The fabricated filament has been used for printing 3D functional prototypes for printing of in-house EESD. The differential scanning calorimeter (DSC) analysis was conducted to understand the effect on glass transition temperature with the inclusion of Graphene (Gr) particles. It has been observed that the reinforced Gr particles act as a thermal reservoir (sink) and enhances its thermal/electrical conductivity. Also, FT-IR spectra realized the structural changes with the inclusion of Gr in ABS matrix. The results are supported by scanning electron microscopy (SEM) based micrographs for understanding the morphological changes.

The application of nanoparticles (NPs) for food safety is increasingly being explored. Zinc oxide (ZnO) and silver (Ag) NPs are inorganic chemicals with antimicrobial and bioactive characteristics and have been widely used in the food industry. However, not much is known about the behavior of these NPs upon ingestion and whether they inhibit natural gut microflora. The objective of this study was to investigate the effects of ZnO and Ag NPs on the intestinal bacteria, namely Escherichia coli, Lactobacillus acidophilus, and Bifidobacterium animalis. Cells were inoculated into tryptic soy broth or Lactobacilli MRS broth containing 1% of NP-free solution, 0, 12, 16, 20 mM of ZnO NPs or 0, 1.8, 2.7, 4.6 mM Ag NPs, and incubated at 37 °C for 24 h. The presence and characterization of the NPs on bacterial cells were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDS). Membrane leakage and cell viability were assessed using a UV-visible spectrophotometer and confocal electron microscope, respectively. Numbers of treated cells were within 1 log CFU/mL less than those of the controls for up to 12 h of incubation. Cellular morphological changes were observed, but many cells remained in normal shapes. Only a small amount of internal cellular contents was leaked due to the NP treatments, and more live than dead cells were observed after exposure to the NPs. Based on these results, we conclude that ZnO and Ag NPs have mild inhibitory effects on intestinal bacteria.

ABSTRACTFourteen Canadian clays and clay admixtures were subjected to simulated nuclear waste repository environments. The present work is concerned with the montmorillonite-dominant materials only. The montmorillonite-dominant samples showed significant leaching on interaction with deionized water. On heating the samples at 200°C for 500 hours, montmorillomites lost intermicellar water completely and acquired cusp-like to cylindrical morphologies. The loss of water and the morphological changes in montmorillonites significantly altered the engineering characteristics. Permeability, shrinkage limits, compactability and shear strength varied in response to the dominant exchange cation in the structure of montmorillonites and the presence of other mineral components in the materials. The synthetic granite water reacted with montmorillonites and led to changes in chemical and mineralogical compositions, crystalline state and engineering properties.
