METHODS: This study longitudinally assessed corneal hysteresis (CH) and the corneal resistance factor (CRF) using the Ocular Response Analyzer in eyes having cataract surgery with LRIs. The relationship between these biomechanical parameters and central corneal thickness (CCT), measured using an ultrasound pachymeter, was also assessed.

RESULTS: The mean CH was 10.0 mm Hg +/- 1.2 (SD) preoperatively, 9.0 +/-

1.6 mm Hg 1 day postoperatively, 9.7 +/- 1.4 mm Hg at 1 week, 9.6 +/- 1.4 mm Hg at 1 month, and 10.2 +/- 1.3 mm Hg at 3 months. The mean CRF was 10.0 +/- 1.5 mm Hg, 8.9 +/- 1.6 mm Hg, 9.5 +/- 1.5 mm Hg, 9.5 +/- 1.4 mm Hg, and 9.5 +/- 1.4 mm Hg, respectively. There were significant differences between preoperative and 1-day

postoperative measurements (P=.005, CH; P=.004, CRF). The CH and CRF were significantly correlated with CCT (r = 0.33, P=.04 and r = 0.40, P=.01, respectively) 3 months postoperatively.

CONCLUSIONS: see more The CH and CRF values decreased 1 day after simultaneous cataract surgery with LRIs but soon recovered to preoperative levels, suggesting there were no significant changes in corneal biomechanical factors after 1 day. Corneal thickness may play a role in biomechanical factors even in such eyes.”
“We report DC magnetization, detailed systematic linear and nonlinear AC magnetic susceptibility and transport for a single phase RuSr2Eu1.4Ce0.6Cu2O10-delta (EuRu-1222) magneto-superconductor. The studied sample is synthesized through standard solid state

SNX-5422 Cytoskeletal Signaling inhibitor reaction route, which is crystallized in single selleckchem phase tetragonal structure with space group I4/mmm. DC magnetic susceptibility measurements revealed that the studied EuRu-1222 is a magneto-superconductor with Ru spins ordering at around 110 K and superconductivity in the Cu-O-2 planes below approximate to 30 K. Temperature dependence of AC susceptibility with different frequency and amplitude variations confirms spinglass behavior with cluster ferromagnetism of the system. Change in the cusp position with frequency follows the Vogel-Fulcher law, which is commonly accepted feature for a spin-glass (SG) system with ferromagnetic clusters. The third harmonic of AC susceptibility (chi(3)) shows that the system undergoes a spin glass transition below 80 K. Superconducting transition temperature (T-c) onset and rho = 0 are seen at around 30 and 18 K without any applied field and the same decreases to 10 and 2 K under 130 kOe applied field. Also low fields isothermal (MH) suggests that ferromagnetic clusters are embedded in spin-glass (SG) matrix. The magnetization versus applied field (MH) loops exhibited ferromagnetic (FM) like behavior with rather small coercive fields. Detailed AC magnetic susceptibility measurements are carried out to unearth the short range magnetic correlations. These results support the spin-glass (SG) formation followed by ferromagnetic clustering effects at low temperatures.
