Objective: To report the clinical presentation, surgical management, and outco mes of rhegmatogenous retinal detachment (RRD) in patients with severe myopia co rrected by posterior chamber phakic (PCP) intraocular lens (IOl) implantation. D esign: Retrospective, noncomparative, interventional case series. Participants: Sixteen eyes of 15 patients in whom retinal detachment developed after PCP IOl i mplantation. methods: The 16 eyes with retinal detachment after PCP IOl implanta tion underwent scleral buckling and pars plana vitrectomy. main Outcome measures : Uncorrected visual acuity, refraction, best spectacle-corrected visual acuity (BSCvA), time between refractive procedure and RRD, vitreoretinal findings, and anatomic reattachment rate. Results: The incidence of RRD after PCP IOl implant ation was 2.07%. mean patient age was 32.9 years (range, 23-46). Nine patients underwent bilateral PCP IOl implantation (60%). Primary RRD developed in 16 ey es of 15 patients. Prophylactic laser photocoagulation was performed in 3 eyes o f 3 patients (18.75%). mean preoperative spherical equivalent (SE) was-17.3±2 .47 diopters (D) (range,-13.75D to-22D). Rhegmatogenous retinal detachment occ urred from 1 to 70 months after PCP IOl implantation (mean, 29.12 months). Each of 11 RRDs (68.75%) had 1 causative break. Fourteen breaks (60.86%) were horse shoe tears and 9 (39.14%) were atrophic holes. Scleral buckling was performed i n 10 eyes (62.5%). Pars plana vitrectomy alone was performed in 5 cases (31.25 %) with posterior breaks. Initial reattachment rate was 90.9%. Final retinal r eattachment was 100%. mean postoperative BSCvA was 20/28 (decimal fraction, 0.7 2±0.25). mean follow-up after retinal detachment surgery was 35.25±17.29 months (range, 12-67 months ). Conclusions: Rhegmatogenous retinal detachment after PCP IOl implantation is rare. Case-control studies are warranted to determine whether this surgical pro cedure increases the risk of retinal detachment in these patie

Quantifying and validating Soybean Seed Emergence model as a Function of Temperature

Developing a model for soybean seed emergence offers a tool producers could use for planting date options and in predicting seedling emergence. In this study, temperature effects on soybean seed emergence were quantified, modeled, and validated. The data for seed emergence model development was generated at varying temperatures, 20°C/12°C, 25°C/17°C, 30°C/22°C, 35°C/27°C, and 40°C/32°C, on two soybean cultivars, Asgrow AG5332 and Progeny P 5333 RY. Time for 50% emergence (t50%) was recorded, and seed emergence rate (ser) was estimated as reciprocal to time at each temperature in both the cultivars. No differences were observed between the cultivars in their response to temperature. A quadratic model (Qm) best described the relationship between t50% and SGR and temperature (R2 = 0.93). Two sets of experiments were conducted to validate the model. In Experiment 1, 17 time-series planting date studies with the same cultivars were used by utilizing diurnal and seasonal changes in temperature conditions. In the second experiment, sunlit growth chambers with 3 different day/night temperatures, low—20°C/12°C, optimum—30°C/22°C, and high—40°C/32°C, and 64 soybean cultivars belonging mG III, Iv, and v, were used. Air temperature and t50 were recorded, and SGR was estimated in all experiments. No differences were recorded among the cultivars for t50% and SGR, but differences were observed among seeding date and temperature experiments. We tested Qm and traditionally used Growing Degree Days models against the data collected in validation experiments. Both the model simulations predictions agreed closely with the observed data. Based on model statistics, R2, root mean square errors (RmSE), and comparison of observations and predictions to assess model performance, the Qm model performed better than the GDD model for soybean seed emergence under a wide range of cultivars and environmental conditions.

利用二维石墨烯易弯曲的特性制备了具有拓扑结构的三维石墨烯(3DGR),并将Rh量子点(Rh QDs)负载于其上得到了三维石墨烯Rh量子点光催化剂,用于光催化制氢反应。由于三维石墨烯具有特殊的拓扑结构,消除了电子在石墨烯层中传递的各向异性,促进了电子进行层间传递,改变了光生电子传递路径,Rh QDs/3DGR催化剂展现出较高的产氢活性和高的稳定性。120 min内累积产氢量为794.2μmol,在520 nm波长下,表观量子效率达到12.6%。该催化剂也具有较高的光电流、较低的过电位(-0.34 v)和较长的荧光寿命(1.37 ns)。

Cerium oxide nanoparticles as promising ophthalmic therapeutics for the treatment of retinal diseases

World Journal of Ophthalmology 2015年第1期5卷 23-30页

Nanotechnology offers exciting new approaches for biology and medicine. In recent years, nanoparticles,particularly those of the rare metal cerium, are showing potential for a wide range of applications in *** oxide nanoparticles or nanoceria are antioxidants and possess catalytic activities that mimic those of super oxide dismutase and catalase, thereby protecting cellsfrom oxidative stress. The retina is highly susceptible to oxidative stress because of its high oxygen consumption and high metabolic activity associated with exposure to light. many retinal diseases progress through oxidative stress as a result of a chronic or acute rise in reactive oxygen species. Diseases of the retina are the leading causes of blindness throughout the world. Although some treatments may delay or slow the development of retinal diseases, there are no cures for most forms of blinding diseases. In this review is summarized evidence that cerium oxide nanoparticles can function as catalytic antioxidants in vivo in rodent models of age-related macular degeneration and inherited retinal degeneration and may represent a novel therapeutic strategy for the treatment of human eye diseases. This may shift current research and clinical practice towards the use of nanoceria, alone or in combination with other therapeutics.

Intravenous immunoglobulin (IvIg) treatment improves mus- cle strength in lambert-Eaton myasthenic syndrome (lEmS), butits specific mod e of action is unknown. We have delineated its mode of action on neuromuscular b locking properties of lEmS IgG. The effect of sera and purified IgG from six pat ients with lEmS on evoked quantal release was investigated after direct applicat ion to the motor nerve terminal by the perfused macro-patch-clamp electrode in mouse hemidiaphragms. The effect of lEmS IgG was analyzed alone and after coinc ubation with different concentrations of IvIg or its Fab fragments. All lEmS ser a and purified lEmS IgG fractions taken before IvIg treatment inhibited evoked q uantal release in a dose-dependent manner. When lEmS IgG was coincubated with a therapeutic IvIg preparation, presynaptic inhibitory activity of lEmS IgG was d iminished in a dose-dependent fashion. monovalent Fab fragments were as effecti ve in neutralizing the activity of lEmS IgG as whole IvIg. These direct neutrali zing effects of IvIg may explain its therapeutic efficacy.

阜新地区地处华北地台,富含煤和金矿床.呈东西向分布的太古宙和元古宙变质地层在华力西期、印支期和燕山期的变形和岩浆活动中发生隆起.金矿赋存于隆起的前寒武纪变质岩石中.成煤期为晚石炭—早二叠纪、早中侏罗纪、晚侏罗—早白垩纪.阜新煤矿和排山楼金矿是辽宁省的主要煤、金产地.由于开采物中的有用物质只占很小的比例,因此提取有用物质的方式不可避免地要破坏当地的环境.矿山开采的每一步骤都对环境产生着负面影响.应用遥感资料进行矿山管理,是采用基于地表物体光谱反射的可视近红外(v N IR )遥感和短波红外(SW IR )遥感,以及基于物体热发光的热红外(TIR )遥感,利用不同的地表光谱反射,将相似的物体区分、分类、填图,并进行土地资源分析.野外工作包括在阜新煤矿和排山楼金矿确定岩石蚀变类型,采集标本,构造测量,对矿山环境进行数码拍照.陆地卫星m SS、Tm 和E Tm +数据是分析研究的基础.应用E R D A S Im A G IN G 软件处理卫星数据.并用E R D A S m apSheets 和v iew Finder 软件划图.应用各种图像处理技术进行图像增强和物体分辨.从卫星图像上直接测量排山楼金矿和阜新煤矿露天采场的多边形周长和面积.从卫星图像上可以看出,阜新煤矿从1980年到2000年环境的恶化.矿山开采产生的废矿堆不仅对矿区造?
