| 1 | Visual problems: a review of prevalence studies on visual impairment in school-age children显示文摘Childhood visual impairment(VI) have a significant impact on the educational achievement, career choices and social life of affected individual, and in children, is mainly due to either preventable or treatable causes. Reliable data on the prevalence and causes of VI in children will guide the development of a systematic vision screening program for its early detection and successful treatment of possible causes. The purpose of this literature review is to summarize the available data on prevalence and causes of VI in school-age children from various regions globally. A discussion on the major findings highlighting the definition criteria, classifications and limitations for further studies is also presented. | Uchenna C.Atowa Rekha Hansraj Samuel O.Wajuihian | 2019 | International Journal of Ophthalmology(English edition)2019，12，6： | 7 |
| 2 | Design and analysis of high birefringence and nonlinearity with small confinement loss photonic crystal fiber显示文摘High birefringence with low confinement loss photonic crystal fiber (PCF) has significant advantages in the field of sensing, dispersion compensation devices, nonlinear applications, and polarization filter. In this report, two different models of PCFs are presented and compared. Both the models contain five air holes rings with combination of circular and elliptical air holes arrangement. Moreover, the elliptical shaped air holes polarization and the third ring air holes rotational angle are varied. To examine different guiding characteristics, finite element method (FEM) with perfectly matched layer (PML) absorbing boundary condition is applied from 1.2 to 1.8 |im wavelength range. High birefringence, low confinement loss, high nonlinearity, and moderate disper-sion values are successfully achieved in both the PCFs models. Numeric analysis shows that model-1 gives higher birefringence (2.75 ×10^-2) and negative dispersion (-540.67 ps/(nm ·km)) at 1.55 |im wavelength. However, model-2 gives more small confinement loss than model-1 at the same wavelength. In addition, the proposed design demonstrates the variation of rotation angle has great impact to enhance guiding properties especially the birefringence. | Rekha SAHA Md.Mahbub HOSSAIN Md.

| 3 | A GFP-based bacterial biosensor with chromosomally integrated sensing cassette for quantitative detection of Hg(Ⅱ) in environment显示文摘A mercury biosensor was constructed by integrating biosensor genetic elements into E. coli JM109 chromosome in a single copy number, using the attP/attB recombination mechanism of λ phage. The genetic elements used include a regulatory protein gene (merR) along with operator/promoter (O/P) derived from the mercury resistance operon from pDU1358 plasmid of Serratia marcescens. The expression of reporter gene gfp is also controlled by merR/O/P. Integration of the construct into the chromosome was done to increase the stability and precision of the biosensor. This biosensor could detect Hg(Ⅱ) ions in the concentration range of 100–1700 nmol/L, and manifest the result as the expression of GFP. The GFP expression was significantly different (P 0.05) for each concentration of inducing Hg(Ⅱ) ions in the detection range, which reduces the chances of misinterpretation of results. A model using regression method was also derived for the quantification of the concentration of Hg(Ⅱ) in water samples. | Himanshu Priyadarshi Absar Alam Gireesh-Babu P Rekha Das Pankaj Kishore Shivendra Kumar Aparna Chaudhari | 2012 | Journal of Environmental Sciences2012，24，5： | 6 |

| 5 | Alkali salts of heteropoly tungstates: Efficient catalysts for the synthesis of biodiesel from edible and non-edible oils显示文摘Alkali salts of tungsten based heteropoly acids with different central atom such as P, Si and Co were prepared and evaluated for transesterification of both edible and non-edible oils to their corresponding fatty acid methyl esters. The catalyst of sodium salt of tungstic acid with Co as central atom(Na5Co W12O40) showed optimum activity towards transesterification compared with other heteropoly tungstates.The catalysts activities were correlated with the observed physico-chemical characteristics derived from FT-infrared(FT-IR), X-ray diffraction(XRD), temperature-programmed desorption of ammonia(NH3-TPD) and carbon dioxide(CO2-TPD). The Na5 Co W12O40catalyst exhibiting high activity even at 65°C is due to the presence of strong acidic as well as basic sites. The disclosed catalyst is tolerable towards water and free fatty acids present in the oils. The influence of catalyst loading, reaction time and reaction temperature is studied to optimize the reaction parameters. | Rekha Sree Sunny Kuriakose | 2015 | Journal of Energy Chemistry2015，24，1： | 4 |
| 6 | Metastatic clear cell variant of hepatocellular carcinoma with an occult hepatic primary显示文摘Metastatic clear cell carcinomas are commonly seen in the kidney and lung. Clear cell variant of hepatocellular carci- noma is an uncommon tumour. Diagnosis is usually made by correlation of histopathology. tumour markers and im- munohistochemistry, especially HepPar 1. In this unusual case of metastatic clear cell carcinoma presenting as Sister Mary Joseph’s nodule, no primary evidence was observed radiologically in the liver, but the level of alfa fetoprotein was markedly elevated. Metastatic clear cell carcinoma of the liver with an occult hepatic primary was diagnosed by immunohistochemical profile of the tumour. | Samir ShahSamir Shah Sudeep Gupta Tanuja Shet Amita Maheshwari Rekha Wuntkal and Kunisshery Mallath Mohandas | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，2： | 3 |

| 8 | Optical force-induced nonlinearity and self-guiding of light in human red blood cell suspensions显示文摘Osmotic conditions play an important role in the cell properties of human red blood cells(RBCs),which are crucial for the pathological analysis of some blood diseases such as malaria.Over the past decades,numerous efforts have mainly focused on the study of the RBC biomechanical properties that arise from the unique deformability of erythrocytes.Here,we demonstrate nonlinear optical effects from human RBCs suspended in different osmotic solutions.Specifically,we observe self-trapping and scattering-resistant nonlinear propagation of a laser beam through RBC suspensions under all three osmotic conditions,where the strength of the optical nonlinearity increases with osmotic pressure on the cells.This tunable nonlinearity is attributed to optical forces,particularly the forward-scattering and gradient forces.Interestingly,in aged blood samples(with lysed cells),a notably different nonlinear behavior is observed due to the presence of free hemoglobin.We use a theoretical model with an optical force-mediated nonlocal nonlinearity to explain the experimental observations.Our work on light self-guiding through scattering biosoft-matter may introduce new photonic tools for noninvasive biomedical imaging and medical diagnosis. | Rekha Gautam Yinxiao Xiang Josh Lamstein Yi Liang Anna Bezryadina Guo Liang Tobias Hansson Benjamin Wetzel Daryl Preece Adam White Matthew Silverman Susan Kazarian Jingjun Xu Roberto Morandotti Zhigang Chen | 2019 | Light(Science & Applications)2019，8，1： | 3 |

| 12 | 氧化铝和氧化锆催化剂上2-取代苯并咪唑和1,5-二取代苯并二氮的合成(英文)显示文摘In this study, alumina, zirconia, manganese oxide/alumina, and manganese oxide/zirconia have been investigated for their catalytic activity in the condensation reaction between o-phenylenediamine and an aldehyde or a ketone to synthesise 2-substituted benzimidazoles and 1,5-disubstituted benzodiazepines respectively. Surface area, surface acidity, and morphology of the catalysts have been analysed and correlated with their catalytic activity. The isolated yields of 2-substituted benzimidazoles and 1,5-disubstituted benzodiazepines are in the range of 30% to 95%. A good correlation between the amount of surface acid sites as well as the surface morphology of the catalysts and the catalytic activity has been observed. This method has been found to be simple and economical. The solid supports could be regenerated and reused without much loss in their activity. Further, the solid supports have been also found to be effective as general catalysts in the condensation of o-phenylenediamine with other substituted aldehydes and ketones. | M. REKHA A. HAMZA B. R.

| 13 | 糖尿病酮症酸中毒患者发生胃肠道出血的预测因素:一项回顾性的观察研究显示文摘背景酮症酸中毒(DKA)是糖尿病一种常见的急性并发症,需要积极的药物治疗。我们旨在研究DKA患者急性胃肠道出血(AGIB)和急性上消化道出血(AUGIB)的发生率及其相关危险因素。方法:我们对本中心2010年1月至2015年12月间收治的DKA病例进行回顾性分析,通过电子病历库收集其人口统计学、临床、实验室、内镜及住院资料。根据有无发生胃肠道出血将患者分为两组。结果:共计234例DKA患者纳入研究,其中27例(11.5%)有AGIB的记录。除2例直肠出血和3例隐匿性出血外,22例(9.4%)表现为呕血。AGIB组与非AGIB组患者年龄、性别和种族的分布无显著差异。两组患者电解质水平、阴离子间隙、pH值及糖化血红蛋白HbA1c的差异亦无统计学意义。然而,AGIB组患者初始血糖水平显著高于非AGIB组(738 mg/dL vs 613 mg/dL,P=0.014)。AGIB组患者病死率也有所升高(7.4%vs 4.8%),尽管差异未达到统计学意义。结论:初始高血糖水平会增加DKA患者发生AGIB的风险。我们还注意到发生AGIB的DKA患者病死率增加,尽管这个增加未达到统计学意义。临床上应更加积极地纠正DKA患者的血糖水平以降低AGIB发生率,从而降低住院病死率。 | Kanthi Rekha Badipatla Preeti Jadhav Sushma Vaddigiri Bharat Bajantri Amandeep Singh Chaitanya Chandrala Vijay S Are Suresh Kumar Nayudu | 2017 | Gastroenterology Report2017，5，4： | 2 |
| 14 | 封闭水循环的制浆厂如何应对无机沉积物的形成显示文摘随着环保压力的不断增加,清水用量已经成为多数制浆厂重点关注的指标。为了满足持续趋紧的排放标准,水系统封闭已成为一种必然趋势。这种趋势对制浆厂产生了重大的影响。由于受制浆原料的限制,亚洲许多浆厂采用非木材原料替代木材原料制浆。即使采用木材原料制浆的工厂,因使用圆木很多是未剥皮的,而树皮中含有的无机盐成分如钙、硅、镁、磷、铝及铵盐等均是导致无机沉积物的主要成分。在制浆过程中通常定义为非过程元素。非木材类制浆原料(主要指农作物秸秆)非过程元素含量相当高。随着无氯漂白及降低成本等诸多因素更复杂的改变,均会导致越来越多的无机和有机沉积物。这些非过程元素和不断封闭的水系统正逐渐成为提高制浆厂运行性能的极大挑战。文中着重介绍采用特殊化学品控制无机沉积物,为减轻浆厂的此类挑战提供解决方案。 | Rekha Bharati Akhlesh Mathur | 2010 | 国际造纸2010，29，4： | 2 |
| 15 | Knowledge,attitude and anxiety pertaining to basic life support and medical emergencies among dental interns in Mangalore City,India显示文摘BACKGROUND: This cross-sectional study aimed to assess the knowledge, attitude and anxiety pertaining to basic life support(BLS) and medical emergencies among interns in dental colleges of Mangalore city, Karnataka, India.METHODS: The study subjects comprised of interns who volunteered from the four dental colleges. The knowledge and attitude of interns were assessed using a 30-item questionnaire prepared based on the Basic Life Support Manual from American Heart Association and the anxiety of interns pertaining to BLS and medical emergencies were assessed using a State-Trait Anxiety Inventory(STAI) Questionnaire. Chi-square test was performed on SPSS 21.0(IBM Statistics, 2012) to determine statistically signifi cant differences(P<0.05) between assessed knowledge and anxiety.RESULTS: Out of 183 interns, 39.89% had below average knowledge. A total of 123(67.21%) reported unavailability of professional training. The majority(180, 98.36%) felt the urgent need of training in basic life support procedures. Assessment of stress showed a total of 27.1% participants to be above highstress level. Comparison of assessed knowledge and stress was found to be insignifi cant(P=0.983).CONCLUSION: There was an evident lack of knowledge pertaining to the management of medical emergencies among the interns. As oral health care providers moving out to the society, a focus should be placed on the training of dental interns with respect to Basic Life Support procedures. | Vinej Somaraj Rekha P Shenoy Ganesh Shenoy Panchmal Praveen S Jodalli Laxminarayan Sonde Ravichandra Karkal | 2017 | World Journal of Emergency Medicine2017，8，2： | 2 |
