Abstract Cow mastitis is the most common disease that affects the dairy farming industry and causes serious harm to dairy cows and humans, and Staphylococcus (S.) aureus is one of the main pathogens that cause mastitis in dairy cows. In this study, a mastitis model was established through the infection of bovine mammary epithelial cells (BMECs) with S. aureus (bacterial concentration of 1 × 10⁹/mL), and these cells and a blank group (untreated) were analyzed by flow cytometry (10000 cells, 200 cells collected per second), hematoxylin and eosin (H&E) staining and immunohistochemistry. In addition, the lncRNAs (long non-coding RNAs) in the… More >

Abstract Bronchial asthma is a common chronic inflammatory disease characterized by airway hyperresponsiveness (AHR), inflammatory cell infiltration, and airway remodeling. F-box/WD repeat-containing protein 7 (FBXW7), an E3 ubiquitin ligase, is required for various endothelial functions, such as cell migration, inflammation, and endothelial integrity. This study aimed to investigate the role of FBXW7 in lipopolysaccharide (LPS)-induced epithelial barrier impairment in bronchial epithelial cells in vitro. By using lentivirus-based technology, FBXW7 was overexpressed or silenced (24 h) in human bronchial epithelial (16HBE) cells, which were treated with LPS or not (24 h). Immunoprecipitation (IP) detection and Western blot analysis were used to evaluate… More >

Abstract A protective action of melatonin (MELAT) on docetaxel (DCT)-induced inflammation, apoptosis, and reactive free oxygen radical (fROS) generation values via blocking of TRPM2 calcium-permeable channel was investigated in different cells except for laryngo-tracheal epithelial (LT-Epi) cells. Hence, the protective action of MELAT on DCT-induced oxidative toxicity and inflammation in LT-Epi tissue and cells of mice were investigated in the current study. MELAT treatment ameliorated DCTinduced mitochondrial ROS in the LT-Epi cells by reducing the generation of fROS (cytosolic and mitochondrial), lipid peroxidation, and depolarization of the mitochondrial membrane, while increasing reduced glutathione (GSH), GSH peroxidase, and total antioxidant status. In… More >

Abstract Boundary effect in digital pathology is a phenomenon where the tissue shapes of biopsy samples get distorted during the sampling process. The morphological pattern of an epithelial layer is greatly affected. Theoretically, the shape deformation model can normalise the distortions, but it needs a 2D image. Curvatures theory, on the other hand, is not yet tested on digital pathology images. Therefore, this work proposed a curvature detection to reduce the boundary effects and estimates the epithelial layer. The boundary effect on the tissue surfaces is normalised using the frequency of a curve deviates from being a straight line. The epithelial… More >

Abstract The pathological examination of ocular tumors has specificities in terms of macroscopic management, microscopic analysis, and molecular examinations requiring special attention. We discuss here the difficulties encountered in the reception in the pathological anatomy laboratory of conjunctival samples, enucleation and orbital exenteration pieces, then detail the diagnostic and theranostic, microscopic and molecular characteristics of ocular tumor pathologies. Conjunctival tumors (epithelial, melanocytic and lymphoid), choroidal tumors (including uveal melanoma) and retinoblastoma are treated. Because of their low frequency and their features, these tumors should be the subject of anatomo-clinical discussions.

Abstract Human-induced pluripotent stem cells (iPSCs) are an accessible source of adult-derived, patient-specific pluripotent stem cells for use in basic research, drug discovery, disease modeling, and stem cell therapy. Improving the accessibility of methods to obtain iPSCs regardless of the cell source can enhance their clinical application. Therefore, our purpose is to report a simple protocol to obtain iPS-like cells from urine-derived renal epithelial cells (RECs) using different extracellular matrices and transfection reagents. In this study, we began by culturing urine-derived cells from healthy donors to establish a primary culture of renal epithelial cells, followed by their characterization. Subsequently, we generated… More >

Abstract Circulating tumor cells (CTCs) are crucial to tumor metastasis, and they usually undergo epithelial– mesenchymal transition (EMT) in order to disseminate from the primary tumor. However, very little is currently known about the relationship between EMT and malignant phenotypes of CTCs in the context of gastric cancer. Therefore, this study aimed to investigate the contribution of EMT to malignant phenotypes of CTCs derived from gastric cancer cells. We xenografted MKN28 gastric cancer cells pretreated with transforming growth factor-beta 1 (TGFβ-1) into nude mice by intravenous injection. Next, we isolated CTCs from the blood of nude mice by gradient centrifugation and… More >

Abstract The wound is induced by several mechanical and metabolic factors. In the etiology of the wound recovery, excessive oxidative stress, calcium ion (Ca²⁺) influx, and apoptosis have important roles. Ca²⁺-permeable TRPM2 channel is activated by oxidative stress. Protective roles of Hypericum perforatum extract (HP) on the mechanical nerve injury-induced apoptosis and oxidative toxicity through regulation of TRPM2 in the experimental animals were recently reported. The potential protective roles in HP treatment were evaluated on the TRPM2-mediated cellular oxidative toxicity in the renal epithelium (MPK) cells. The cells were divided into three groups as control, wound, and wound + HP treatment… More >

Abstract By virtue of expressions of glial and neural surface markers and capability of neurotransmitter metabolism, amniotic epithelial cells are considered as candidate cell type for transplantation strategies to treat neurological disorders. Previously, we have reported neurotrophism exhibited by human amniotic epithelial cells when transplanted after spinal cord injury in bonnet monkeys. Amniotic epithelial cells were believed to secrete an “Epidermal Growth Factor (EGF) - like” factor and exact identification was not made. At this juncture, through the present study it was found that, chicken neural retinal cells when grown alone failed to survive and contrarily when either co-cultured with chicken… More >

Abstract The isolation of viable enterocytes, villi and crypts from the small intestine of a feral bird (Columba livia) is important for performing physiological experiments in ecologically relevant processes of membrane transport. The effectiveness of mechanical disruption, enzymatic digestion and chelating agents were compared. The objectives were to isolate enterocytes, villi and crypts from the small intestine of young pigeons; to evaluate the viability of the isolated intestinal epithelial cells isolated; and to verify the integrity of enterocytes by biochemical features. Enzymatic and mechanical methods yielded both elongated columnar and spherical cells. With the chelating method villi and crypts were obtained.… More >
