Abrupt visual loss during anti-vascular endothelial growth factor treatment for type 3 neovascularization

International Journal of Ophthalmology(English edition) 2019年第3期12卷 480-487页

作者： Jae Hui Kim Young Suk Chang Jong Woo Kim Chul Gu Kim Dong Won lee Department of Ophthalmology Kim's Eye Hospital Konyang University College of Medicine Department of Ophthalmology Konyang University College of Medicine

AIM: To investigate the incidence of abrupt visual loss and its associated factors, during anti-vascular endothelial growth factor(VEGF) treatment for type 3 ***: This retrospective study included 137 eyes that were newly diagnosed with type 3 neovascularization. All eyes were treated with anti-VEGF therapy. Abrupt visual loss was defined as loss of 5 or more lines in best-corrected visual acuity(BCVA) in comparison to the previous visit. The incidence and timing of abrupt visual loss as well as the factors associated with it, were determined. In addition, the BCVA at the final follow-up was compared between the eyes with and those without abrupt visual ***: The mean follow-up period was 42.4±18.9 mo after diagnosis, and abrupt visual loss was noted in 22 eyes(16.1%) at a mean of 19.6±13.9 mo. Abrupt visual loss was found to be associated with subretinal hemorrhage in 11 eyes(50.0%), development of or increase in the height of pigment epithelial detachment with fluid in 8 eyes(36.4%), and tears in the retinal pigment epithelium in 3 eyes(13.6%). The logarithm of minimum angle of resolution(logMAR) mean BCVA at the final follow-up was 2.07±0.67(Snellen equivalents: 20/2349) and 1.00±0.55(20/200) in eyes with and without abrupt visual loss, respectively. BCVA was significantly worse in the eyes with abrupt visual loss(P<0.001).CONCLUSION: Abrupt visual loss is noted in 16.1% of patients with type 3 neovascularization and is associated with poor visual outcome. Additional studies are needed to determine how abrupt visual loss can be prevented.

Improvement of oxidation resistance in graphite for MgO-C refractory through surface modification

引用

Transactions of Nonferrous Metals Society of China 2014年第S1期24卷 119-124页

Graphite, used as a carbon source in a conventional magnesia-carbon(MgO-C) refractory, was modified with an acid reagent, resulting in a negative charge on the surface of graphite, to enhance the coating efficiency of aluminum(Al) phase, which was compared to the pristine graphite through its dispersibity and oxidation behavior. The graphite particles with and without surface modification were added, respecticely, in an Al(NO3)3 suspension used as a coating reagent, and then filtered at room temperature. The modified graphite shows better disperbility than the pristine graphite, indicating that the coating efficiency of Al precursor is enhanced in the modified graphite. With respect to oxidation behavior, the modified graphite without the coating layer is totally reacted with oxygen at heat treatment of 900 °C in air. However, the Al-coated graphite starts to react with oxygen at heat treatment of 900 °C and fully reacted with oxygen at heat treatment of 1000 °C, showing the gray and white colors, respectively. It is verified that the Al layer is individually and uniformly formed on the surface of graphite and the oxidation resistance of graphite is enhanced owing to the increased coating efficiency of Al precursor.

Leader-following consensus criteria for multi-agent systems with time-varying delays and switching interconnection topologies

引用

Chinese Physics B 2012年第11期21卷 144-153页

作者： M.J.Park O.M.Kwon Ju H.Park S.M.lee E.J.Cha School of Electrical Engineering Chungbuk National University Department of Electrical Engineering Yeungnam University School of Electronic Engineering Daegu University Department of Biomedical Engineering School of MedicineChungbuk National University

We consider multi-agent systems with time-varying delays and switching interconnection topologies. By con- structing a suitable Lyapunov-Krasovskii functional and using the reciprocally convex approach, new delay-dependent consensus criteria for the systems are established in terms of linear matrix inequalities （LMIs）, which can be easily solved by using various effective optimization algorithms. Two numerical examples are given to illustrate the effectiveness of the proposed methods.
