Cytotoxic effect of silica nanoparticles on human retinal pigment epithelial cells.

In recent years, the use of nanotechnology-based methods has become widespread in the treatment of ocular diseases. Silica nanoparticles (SiO NPs) are most common used NPs in medical field due to their physicochemical properties. SiO NPs can easily cross biological membranes and interact with basic biological structures, causing structural and functional changes in cells.

Novel benzoylthiourea derivatives had differential anti-inflammatory photodynamic therapy potentials on in vitro stimulated mammalian macrophages.

Novel benzoylthioureas, N-((5-chloropyridin-2yl)carbamothioyl)benzamide, (HL), N-((2-chloropyridin-3yl)carbamothioyl)benzamide, (HL), N-((5-bromopyridin-2yl)carbamothioyl)benzamide, (HL) and N-(Naphthalene-1-yl(phenyl)carbamothioyl)benzamide, (HL), were synthesized. Their characterizations were made by FT-IR,H NMR and C NMR spectrophotometric analysis. Single crystal X-ray diffraction measurements were conducted to determine the crystal structure of HL and HL.

Protozoan and Microbial Pathogens of House Cats in the Province of Tekirdag in Western Turkey.

Domestic felines' re-emerging infectious and neglected zoonotic diseases are a significant focus of global "One Health" efforts. This study aimed to rapidly diagnose 14 pathogens, including zoonoses by using PCR primers in 167 client-owned symptomatic cats, routinely accepted to the Veterinary Clinics of Tekirdag. The prevalence of pathogens investigated were as follows: (24%), (2.

Impacts of Specific Cryoprotectants on Sperm Freezing and Relationships Between Cryodamage and Oxidation Stress Parameters in Awassi Ram Sperm.

Materials And Methods: The sperm samples diluted with Salamon's tris-citrate (TRIS) containing 20% centrifuged egg yolk and 0.

Study on crystallographic and electronic structure of micrometre-scale ZnO and ZnO:B rods via X-ray absorption fine-structure spectroscopy.

X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine-structure (EXAFS) spectra were recorded to investigate the electronic structure and local crystal structure of ZnO and ZnO:B powders produced via hydrothermal synthesis. ZnO and ZnO:B grow as micrometre-scale rods with hexagonal shape, as confirmed by scanning electron microscopy micrographs. The number of broken ZnO:B rods increases with increasing B concentration, as observed in the images, due to B atoms locating in between the Zn and O atoms which weakens and/or breaks the Zn-O bonds.
