AIM: To evaluate the efficacy and safety of three consecutive monthly injections of intravitreal ranibizumab for the treatment of polypoidal choroidal vasculopathy(PCV) in ***: A retrospective chart review of 25 patients(27 eyes) with PCV was conducted. Patients received three initial monthly intravitreal injections(0.5 mg) of ranibizumab and were monitored monthly for 12 mo from January 2010 to October 2011. Reinjection of ranibizumab after three initial monthly loading was administered on an as-needed basis, guided by the optical coherence tomography(OCT), fluorescein angiography(FA) and indocyanine green angiography(ICGA). The main outcomes were the changes of the mean best corrected Snellen visual acuity(VA), central macular thickness(CMT) by OCT, the changes of polyps and branching vascular network by FA and ICGA, and total number of injections received by patients during the 12 ***: The mean best corrected Snellen visual acuities at baseline, 1, 3, 6 and 12 mo after primary injection were 0.77 ±0.59, 0.76 ±0.53, 0.70 ±0.47, 0.63 ±0.43,0.61 ±0.43, 0.62 ±0.42 log MAR, respectively, and showed significant improvement at 3, 6, 12mo(P =0.003, P =0.002,P =0.018, Wilcoxon signed-rank test). The mean CMT at baseline, 1, 2, 3, 6, and 12 mo was 312.41 ±66.38 μm,244.59 ±71.47 μm, 232.32 ±69.41 μm, 226.69 ±69.03 μm,228.62 ±37.07 μm, 227.59 ±51.01 μm respectively, and showed significant reduction(all P <0.001, Wilcoxon signed-rank test). Polypoidal lesions resolved on ICGA in 3 eyes(11.1%) and a branching vascular network remained in all 24 eyes(88.9%). A total of 106 injections were given in the 12-month period, which equaled to a mean of 3.92(range, 3-6) times. Sixteen of the 27 treatedeyes had additional 1.56 ±0.91 injections. The others(11eyes) had just 3 consecutive ***: An initial loading dose of three monthly ranibizumab injections is a safe and effective method in treating PCV, with visual and anatomical improvement over one ye

Oxygen vacancy engineering for tuning the catalytic activity of LaCoO_(3) perovskite

引用

Journal of Rare Earths 2024年第3期42卷 506-514,I0003页

作者： Jeong Hyun Cho Minjae Kim Inchan Yang Kyung Tae Park Chang Houn Rhee Hai Woong Park Ji Chul jung Department of Chemical Engineering Myongji UniversityYongin 17058Republic of Korea Institute of Advanced Composite Materials Korea Institute of Science and TechnologyWanju-gunJeollabuk-do 55324Republic of Korea Iron&Steel Process Engineering Research Group POSCOPohang 37859Republic of Korea Hydrogen Research Center Research Institute of Industrial Science&Technology(RIST)Pohang 37673Republic of Korea

Herein, we attempted to engineer oxygen vacancies on the surface of LaCoO_(3) perovskite through simple post-treatments(acid or reductive thermal treatments). Acid treatment induces oxygen vacancies through the selective etching of the La cations, whereas thermal treatment in a reducing atmosphere generates oxygen vacancies by directly removing lattice oxygen. The characterization results confirm that the number of surface oxygen vacancies, which are crucial in various catalytic oxidation reactions,considerably increases in the LaCoO_(3) catalysts treated with acid or reducing gas. Acid treatment enriches the oxygen vacancies while maintaining the structure of the LaCoO_(3) catalysts, which can not be achieved through reductive thermal treatment. Therefore, the acid treatment is considered a promising technique for oxygen vacancy engineering of perovskite catalysts for tuning their catalytic activities. Furthermore,the catalytic activities of the posttreated LaCoO_(3) catalysts for CO oxidation were evaluated and are noted to be considerably better than those of the pristine LaCoO_(3) catalyst due to their abundant oxygen vacancies. Consequently, we conclude that the oxygen vacancies of perovskite catalysts can be effectively engineered via two simple methods and play a significant role in CO oxidation.
