Correlation of In Vivo and In Vitro Methods in Measuring Choroidal Vascularization Volumes Using a Subretinal Injection Induced Choroidal Neovascularization Model

Background： In vivo quantification of choroidal neovascularization （CNV） based on noninvasive optical coherence tomography （OCT） examination and in vitro choroidal flatmount immunohistochemistry stained of CNV currently were used to evaluate the process and severity of age-related macular degeneration （AMD） both in human and animal studies. this study aimed to investigate the correlation between these two methods in murine CNV models induced by subretinal injection. Methods： CNV was developed in 20 C57BL6/j mice by subretinal injection of adeno-associated viral delivery of a short hairpin RNA targeting sFLT-1 （***- 1）, as reported previously. After 4 weeks, CNV was imaged by OCT and fluorescence angiography. the scaling factors for each dimension, x, y, and z （ktm/pixel） were recorded, and the corneal curvature standard was adjusted from human （7.7） to mice （1 .4）. the volume of each OCT image stack was calculated and then normalized by multiplying the number of voxels by the scaling factors for each dimension in Seg3D software （University of Utah Scientific Computing and Imaging Institute, available at http：//***/cibc-software/***）. Eighteen mice were prepared for choroidal flatmounts and stained by CD31. the CNV volumes were calculated using scanning laser confocal microscopy after immunohistochemistry staining. Two mice were stained by Hematoxylin and Eosin for observing the CNV morphology. Results： the CNV volume calculated using OCT was, on average, 2.6 times larger than the volume calculated using the laser confocal microscopy. the correlation statistical analysis showed OCT measuring of CNV correlated significantly with the in vitro method （R： = 0.448, P = 0.001, n = 18）. the correlation coefficient for CNV quantification using OCT and confocal microscopy was 0.693 （n = 18, P = 0.001 ）. Conclusions： there is a fair linear correlation on CNV volumes between in vivo and in vitro methods in CNV models induced by subretinal injectio

2023年6月15日,美国外交关系委员会发表题为《“乌克兰IT军队”在俄罗斯的网络行动态势》的文章,分析了“乌克兰IT军队”对俄罗斯目标开展网络攻击的活动情况,论述了攻击者如何在战争期间开展网络空间行动,并展示了其技术能力的界限,以及其偏离网络行动国际规范和攻击民用目标的意愿。该组织虽然可能不像其他国家支持的网络团体那样以同样先进的技术水平运作,但其可能提供了一个“独特窗口”,以供人们了解网络攻击方的决策和行动,以及如何在战争期间利用网络空间等。
