Patients received twice-daily cyclosporine 0.05% in 1 eye and an artificial tear in the other eye from 1 month before to 2 months after second-eye surgery. Outcomes were evaluated at baseline and 2 months

after second-eye surgery.

RESULTS: The study enrolled 28 eyes of 14 patients. At baseline, there were no statistically P5091 mouse significant between-group differences in outcome measures. Two months postoperatively, the cyclosporine group had significantly lower mean uncorrected distance visual acuity than the artificial tear group (0.11 logMAR +/- 0.03 [SD] [20/25 Snellen equivalent] versus 0.19 +/- 0.05 logMAR [20/30]; P = .045) as well as significantly lower mean corrected distance visual acuity (0.0 +/- 0.02 logMAR [20/20] versus 0.1 +/- 0.02 logMAR [20/25]; P = .005) and corneal staining scores (0.210 +/- 0.07 versus 0.645 +/- 0.18; P = .034). Treatment with cyclosporine

0.05% also improved contrast sensitivity, conjunctival staining, and tear breakup time. Significantly more patients preferred the eye treated with cyclosporine 0.05% to the eye treated with artificial tears (57.1% versus 14.3%; P = .007).

CONCLUSION: Cyclosporine 0.05% therapy reduced dry-eye signs and improved visual quality after multifocal IOL implantation.”
“The present study describes the behaviour of photosystem II (PSII) in Amaranthus hypochondriacus buy WH-4-023 and Amaranthus hybridus under water stress conditions, assessed by the analyses of the polyphasic rise in chlorophyll a fluorescence (O-J-I-P). We determined the adaptive behaviour in relation to the regulation of the different functional and structural parameters of PSII, which was a direct and rapid response due to changes in soil water status indicated by a decrease in leaf water potential and relative water content. It allows for the identification of specific key or limiting chlorophyll fluorescence parameters which could be used to identify traits conveying tolerance. For the above partial processes of PSII

function studied, it seems that A. hybridus remained the more stable upon water stress (after 17 PF-562271 days of withholding water), concerning the specific energy fluxes of absorption/reaction centre (ABS/RC) apparent (antenna size) and trapping/reaction centre (TR/RC) (maximum trapping flux), as well as the density of the reaction centres/cross section (RC/CS) and the phenomenological trapping flux/cross section (TR(o)/CS). It was clear that amaranth adjusts the non-photochemical (k(n)) deactivation constant of PSII and to a less extend also the photochemical (k(p)) deactivation constant by means of photoregulation, which forms the basis of the quenching of chlorophyll a fluorescence.
