Ultrastructural and mechanical effects of collagen cross-linking treatment on human corneo-scleral tissues

Choi S., Jung G.B., Cheong Y., Shin J.-H., Jin K.-H., Park H.K., Kyung Hee University, KR

The aim of this study was to quantitatively examine the immediate effects of a photooxidative collagen cross-linking treatment with photosensitizer riboflavin and 370 nm UVA light in in vitro rabbit dermal collagen fibrils. These effects [...]

Nanostructural Changes in Surface of Stainless Steel Archwires Combined with Orthodontic Conventional and Self-Ligating Brackets

Choi S., Joo H., Cheong Y., Lee S., Kim S., Park H.K., Park Y.-G., Park H.K., Park Y.-G., Kyung Hee University, KR

It is well-known that the frictional force between the archwire (AW) and the bracket reduces the efficiency of orthodontic treatment. It is affected not only by geometry of self-ligating brackets but also by physical changes [...]

Nanostructural Effects of Mitomycin C Applications on Scleral Collagen Fibrils: Atomic Force Microscopy Observation

Choi S., Cheong Y., Kwon E., Jung G.B., Lee H.J., Shin J.-H., Jin K.-H., Park H.K., Kyung Hee University, KR

This study was to investigate the effects of Mitomycin C on the scleral collagen surfaces by atomic force microscopy (AFM). Two non-contact mode AFM machines were used to observe changes in the morphological characteristics of [...]
