Tumour cell surface-expressed programmed death-ligand 1 (PD-L1) may bind to T cell-expressed programmed cell death-1 (PD-1). Through a decrease in T-cell activity and an acceleration of their apoptosis, the interaction between PD-1 and PD-L1 may suppress T-cell responses. High amounts of PD-L1 are expressed by a variety of malignancies. This is the first investigation of PD-L1 expression in Iraq, specifically in the Basrah governorate, using BC, CRC, and PC patients. One hundred and one blood samples from patients with prostate, colorectal, and bladder cancer were obtained for this study. Howe
Read MoreSchiff bases (azomethines) are well-studied structures, and their synthesis from an amine and an aldehyde or ketone is reasonably straightforward. Because of their Pharmaceutical uses, they have become important compounds. Aim of study: synthesis new Schiff bases and their complexes and evaluated their spectra. The ligands were prepared from schiff bases by condensation method derived from the drug amine (methyl 4-amino benzoate) with the aldehydes (2-hydroxybenzyldehyde) LS1 and (4,2-dihydroxybenzyldehyde) LS2. The ligands were characterized by FT-IR, Ultraviolet visible, Mass spectra, 1H-NMR
Read MoreZinc oxide (ZnO) nanoparticles have attracted significant interest due to their exceptional properties, which include broad multi-domains such as piezoelectric nature, high thermal conductivity, and antimicrobial activity. This review examines the various synthetic methods used to produce ZnO nanoparticles, focusing on their advantages and limitations. The article broadly analyzes methods for synthesizing zinc oxide and zinc oxide nanoparticles and their applications in various industrial fields, including optoelectronics, sensor technologies, biomedical fields, and environmental improvement.
Read MoreThe present work deals with the synthesis of modified clay-based adsorbents using experimental design methodology, more specifically full factorial design. The aim of this study is to develop effective adsorbents for the removal of contaminants from effluents. Design-of-experiments methodology was used to optimize key synthesis factors, such as the modifying agent, its concentration and the contact time. The responses studied were methylene blue dye removal rate and iodine number. The results obtained showed the significant influence of modifier concentration on the responses studied. In addit
Read MorePopulation growth and the development of industrial and port activities along the entire coastline of the city of Abidjan are enormous sources of water pollution. This pollution undermines the quality of these waters by creating ecological conditions that are inadequate for normal aquatic life. To combat this pollution, this study consisted of analyzing the ecological state of the waters of the Abidjan coastline with a view to identifying their ability or inability to promote biological balance within them. Temperature, pH, salinity, conductivity, dissolved oxygen, dissolved oxygen saturation,
