Standardization of meibomian gland dysfunction in an Egyptian population sample using a non-contact meibography technique

AIM:To develop normative data for meibomian gland dysfunction(MGD)parameters,using non-contact meibography technique of Sirius Costruzione Strumenti Oftalmici(CSO)machine,in an Egyptian population sample.METHODS:Observational,cross-sectional,analytic study,in which 104 Egyptian volunteers were included.Both upper lids were examined,using“Sirius CSO”machine.Each eyelid was given a degree of meibomian gland loss(MGL),which was calculated by the software of the machine.RESULTS:Mean percentage MGL in right upper lid was of 30.9%±12.6%,and that of left upper lid was 32.6%±11.8%.Thirty-four volunteers(32.7%)had first-degree MGL in their right upper lid,and 67.3%had second-degree loss.One volunteer(1%)had zero-degree MGL in left upper lid,28(26.9%)had first-degree loss,and 75(72.1%)had second-degree loss.Degree of MGL in right upper eyelid was not related to age,but degree of MGL in left upper eyelid increased with age.There was statistically significant difference between both genders for degree of MGL in right eye(P=0.036)and in left eye(P=0.027).CONCLUSION:Noncontact meibography is a useful non-invasive tool for diagnosing MGL.MGL is diagnosed in 100%of apparently normal individuals;26.9%-32.7%of which have first-degree MGL,and 67.3%-72.1%have second-degree MGL.

PDE Standardization Analysis and Solution of TypicalMechanics Problems

A numerical approach is an effective means of solving boundary value problems(BVPs).This study focuses on physical problems with general partial differential equations(PDEs).It investigates the solution approach through the standard forms of the PDE module in COMSOL.Two typical mechanics problems are exemplified:The deflection of a thin plate,which can be addressed with the dedicated finite element module,and the stress of a pure bending beamthat cannot be tackled.The procedure for the two problems regarding the three standard forms required by the PDE module is detailed.The results were in good agreement with the literature,indicating that the PDE module provides a promising means to solve complex PDEs,especially for those a dedicated finite element module has yet to be developed.

芍药胼胝质合成酶基因家族鉴定及PlCalS5功能分析

【目的】CalS家族在调控植物胼胝质合成方面具有重要作用,鉴定芍药CalS家族成员,并进行生物信息学和表达模式分析,为芍药属远缘杂交不亲和研究提供依据。【方法】通过荧光显微镜观察自交、杂交柱头内花粉管生长过程及花粉萌发情况;测定柱头所含胼胝质、内源脱落酸含量(ABA)以及β-1,3-葡聚糖酶活性;分段克隆8个PlCalS并进行序列分析;使用Expasy、MEME、TBtools、MEGA 7.0等软件和在线工具预测PlCalS家族成员蛋白质基本理化性质、保守基序并构建系统发育进化树;利用qRT-PCR技术检测8个PlCalS在自交24 h、杂交24 h、杂交36 h的相对表达水平;对CalS5进行多序列比对并构建系统进化树,分析PlCalS5响应不同浓度ABA处理的表达特征。【结果】花粉管荧光显微观察发现杂交柱头内发生较为严重的胼胝质堵塞从而影响花粉管的正常生长及花粉的萌发。测定柱头内胼胝质含量发现多数时期自交柱头均低于同时期杂交柱头的含量,柱头内β-1,3-葡聚糖酶活性、ABA含量变化均具有一定的规律性。通过对结构域的完整性分析鉴定芍药PlCalS基因家族成员,后经同源性比对分析命名8个CalS,均含有15个保守基序且在PlCalS基因家族中的分布类似。多物种系统进化关系表明,CalS家族可分为3个分支,PlCalS家族仅分布在2个分支,其中PlCalS5与牡丹、拟南芥和番茄的CalS5亲缘关系较近。生物信息学分析结果表明8个家族成员编码1745—1951个氨基酸,原子总数为28583—31870个,等电点为7.99—9.13。对转录组FPKM值的分析表明,PlCalS家族成员在相同时期杂交处理中有较高表达,相同处理情况下在杂交36 h时高表达;荧光定量PCR表明,8个基因的相对表达量在自交24 h时均低于杂交24 h和杂交36 h。经两个浓度的ABA处理,发现PlCalS5对高浓度的ABA更为敏感。【结论】芍药CalS家族有8个基因成员且具有较高的保守性,8个家族成员对芍药胼胝质的生成起重要调控作用;大部分时期PlCalS在杂交柱头的表达量高于自交柱头,可能参与胼胝质异常沉积的过程;芍药杂交柱头异源花粉的刺激可能会增强某个ABA合成途径,ABA可能通过正调控胼胝质基因诱导胼胝质的积累,从而抑制花粉的萌发与花粉管的伸长,影响授粉亲和性。

Standardization of apple cancellation test for neglect patients in Korea:An observational study

BACKGROUND Neglect can be divided into two types using apple cancellation test(apple test):Egocentric neglect(EN)and allocentric neglect(AN).However,in South Korea,apple test results and decision criteria are still largely dependent on tests by foreign countries.AIM To establish a new South Korea standard and improve the accuracy of neglect assessment,the apple experiment was standardized in this study.METHODS This study was conducted on 223 healthy subjects for a total of 7 mo from August 2021 to February 2022.Standardization was carried out using the original apple test developed by Bickerton in 2011.In scoring for the apple test,total omission error refers to the number of missed targets(full apple)in the entire test sheet(left,middle,and right area).The score for EN is the difference between the correct number of right area and the correct number of left area(excluding the middle area).For AN,the score is difference between the number of left opening apples and number of right opening apples(including the middle area).Linear regression analysis was used for standardization using the general characteristics of subjects and the results of the apple test.RESULTS The cut-off score,which is the standard value indicating the pathological condition by combining the results of all subjects,is as follows:Total omission error(5),error for EN(2),and error for AN(2).Also,differences in cut-off score according to age were found.CONCLUSION This study will be helpful in facilitating a more accurate differential diagnosis of neglect.

基于CALS及Surpac-FLAC^3D耦合技术的复杂空区稳定性分析

由于受地质条件和探测技术的限制,传统探测方法很难获得复杂空区精确的实际空间分布形状,由此得到的空区用于建立数值分析模型显得过于粗糙,在此基础上进行空区稳定性分析的可靠性程度不高。采用空区激光自动扫描系统(CALS)对复杂空区进行激光扫描,在获得精准三维点云数据的基础上,运用Surpac软件模拟出空区的三维地质模型,通过耦合方法可以在FLAC3D中生成与实际空区空间分布一致的数值模型,提高复杂空区稳定性计算的准确性和可靠性。选取三道庄露天矿的地下空区作为工程实例,利用CALS获得不规则空区的实际空间边界。在此基础上,运用Surpac进行三维块体模拟,研究Surpac与FLAC3D模型耦合技术,成功地将三维模型数据导入FLAC3D中,结合现场实际勘测的围岩力学参数,对空区进行静力计算,分析空区的稳定性。
