A significantly higher expression of FoxP3 within the CD4(+) CD25(+) CD127(low) subset for RF and BL compared to the AR group was observed. In conclusion, pre- transplant anti- donor alloreactivity and FoxP3 expression within the CD4(+) CD25(+) CD127(low) subpopulation might prove useful to further define the patient’s risk for AR.”
“PURPOSE: To use anterior segment optical coherence tomography (AS-OCT) to evaluate the

stability of a recently released angle-supported phakic intraocular lens (pIOL) in the anterior segment with changes in check details pupil diameter.

SETTING: Keratoconus Unit, Vissum Corporation, Alicante, Spain.

METHODS: In this observational cross-sectional study of consecutive eyes with moderate to high myopia, an AcrySof Cachet pIOL was implanted with the aim of minimizing the refractive error An analysis of the position and stability of the pIOL before and after pharmacologic pupil dilation was performed 3 months postoperatively using the Visante AS-OCT system A measurement protocol that included several anatomic parameters was developed and applied; the parameter values before and after dilation were compared

RESULTS: Twenty eyes

of 20 patients ranging in age from 24 to 48 years old were evaluated. The anterior chamber depth increased significantly MK-2206 cell line with pupil dilation (mean change 0.06 mm +/- 0.08 [SD]) (P< 01) A significant change was also observed in the distance between the center of the cornea at the endothelial plane and the anterior surface of the pIOL (mean change 0 03 +/- 005 mm) (P = 01). The distances between the peripheral edges of the pIOL and the corneal endothelium and the distance between the crystalline lens and the pIOL did not change significantly

(P >= 14)

CONCLUSION: The angle-supported pIOL showed excellent intraocular behavior after pupil dilation, with no shortening of the distance between the pIOL and corneal endothelium at the center or peripheral edges of the pIOL.

“In an abrasive chemical mechanical polishing (CMP) process, materials were considered to be removed by abrasive sliding and rolling. Abrasive sliding has been investigated by many molecular dynamics (MD) studies; while abrasive rolling was usually considered to be negligible and therefore was rarely investigated. In this paper, an MD simulation was used to study the effects of abrasive rolling on material removal and surface finish in the CMP process. As the silica particle rolled across the silicon substrate, some atoms of the substrate were dragged out from their original positions and adhered to the silica particle, leaving some atomic vacancies on the substrate surface. Meanwhile, a high quality surface could be obtained.
