“PURPOSE: To compare and evaluate the visual and refractive outcomes of myopic wavefront-guided photorefractive keratectomy (PRK)
and foldable phakic intraocular lens (pIOL) implantation for myopia.
SETTING: Department of Ophthalmology, Haaglanden Medical Center, The Hague, The Netherlands.
DESIGN: Comparative case series.
METHODS: The differences in visual acuity and residual refractive outcomes after wavefront-guided PRK and Artiflex foldable pIOL implantation were compared in eyes with low to moderate myopia (spherical error -4.0 to -7.0 diopters [D]; maximum cylinder 2.25 D). One-year follow-up results are presented.
RESULTS: At 1 year postoperatively, the mean decimal Snellen uncorrected distance visual acuity was 1.05 +/- 0.21 (SD) in the PRK group (60 eyes) and 1.04 +/- 0.21 in the pIOL group (33 eyes) and the mean corrected Navitoclax distance visual acuity (CDVA), 1.21 +/-
0.18 buy CH5183284 and 1.24 +/- 0.13, respectively. In the PRK group, 21.7% of eyes lost 1 to 3 lines of CDVA and 11.7% of eyes gained 1 or 2 lines. In the pIOL group, no eye lost lines of CDVA and 42% gained 1 or 2 lines. At 1 year, 80.0% of eyes in the PRK group and 90.9% of eyes in the pIOL group were within +/- 0.50 D of the spherical equivalent.
CONCLUSION: There were no statistically significant differences in safety and efficacy between the pIOL group and the PRK group at 1 year. However, the percentage of eyes that gained lines of CDVA was significantly higher in the pIOL group.”
“The magnetocaloric effect (MCE) in antiferromagnetic borocarbide superconductor RNi2B2C (R = Dy, Ho, and Er) compounds have been investigated by measuring the temperature and field dependences of heat capacity. An inverse MCE was observed, which is attributed to the nature of the antiferromagnetic state under low magnetic field and at low temperatures for the
present RNi2B2C compounds. A normal giant/large MCE was observed under higher magnetic field change, which is related to a field-induced first-order metamagnetic transition from antiferromagnetic to ferromagnetic state. For a field change of 5 T, the maximum values of magnetic entropy change (-Delta S-M(max)) reach 17.6, 17.7, and 9.8 J kg(-1) K-1 for R = Dy, Cilengitide molecular weight Ho, and Er, respectively. The corresponding values of maximum adiabatic temperature changes (Delta T-ad(max)) are 9.7, 11, and 4.6 K. The present results indicated the antiferromagnetic borocarbide superconductor RNi2B2C compounds could be promising candidates for low temperature magnetic refrigeration.

“Two flavonoids 3,5,7,3′,4′-pentahydroxy-6-prenylflavonol (1) and 3,5,7,3′,4′-pentahydroxy-8-methyl-6-prenylflavonol (2) were isolated from the ethyl acetate extract of sheaths of Vellozia kolbekii Alves (Velloziaceae). This is the first time that compound 2 has been described.
