The aim of the study was to estimate the effect of nornicotine on endothelial EA.hy926 cells in the context of its impact on cell-cell junctions. The objective of the study was to determine the relationship between junctional proteins and F-actin after treating the cells with nornicotine. After 24 h of cell exposure to 0.08, 0.12, and 0.16 ng/mL nornicotine, analysis was performed of cell death...
Merkel cells, discovered by Friedrich Sigmund Merkel in 1875, are found in multiple regions of the skin and some mucosa and make contact with specialized nerve fibers, participating in the perception of touch. However, Merkel cells have thus far not been described on the ocular surface. The purpose of this study was to investigate the distribution and ultrastructure of Merkel cells on the ocula...
herpetosiphon giganteus is a filamentous gliding bacterium. gliding motility is the movement of the cells over surfaces without the aid of flagella. the mechanism responsible for bacterial gliding motility has not been known and there are only a few data on herpetosiphon giganteus. the aim of this study was to observe the ultrastructure and negative staining of isolated strains of herpetosiphon...
