4Visco chop-a new technique for nucleus separation for soft cataracts in femtolaser assisted cataract surgery显示文摘INTRODUCTION Femtosecond laser technology,introduced clinically for ophthalmic surgery as a technique for creating lamellar flaps in laser in situ keratomileusis(LASIK),has recently been developed into a tool for cataract surgery.Preliminary experience for femtosecond laser-assisted cataract surgery show appropriate safety and efficacy,and possible advantage over conventional cataract surgery[1-4].The ability of the femtosecond laser to fragment the lens results in the need for less ultrasound energy to be expended inside the eye.Several studies indicate that less effective phacoemulsification time is needed to emulsify theSri Ganesh Sheetal Brar 2015International Journal of Ophthalmology(English edition)2015,8,4:3
5Comparative evaluation of microscopy,OptiMAL® and 18S rRNA gene based multiplex PCR for detection of Plasmodium falciparum & Plasmodium vivax from field isolates of Bikaner,India显示文摘Objective:To evaluate microscopy,OptiMAL? and multiplex PCR for the identification of Plasmodium falciparum(P.falciparum) and Plasmodium vivax(P.vivax) from the field isolates of Bikaner,Rajasthan(Northwest India).Methods:In this study,a multiplex PCR(P.falciparum and P.vivax) was further developed with the incorporation of Plasmodium malariae(P.malariae) specific primer and also a positive control.The performance of microscopy,plasmodium lactate dehydrogenase(pLDH) based malaria rapid diagnostic test OptiMAL? and 18S rRNA gene based multiplex PCR for the diagnosis of P.falciparum and P.vivax was compared.Results:The three species multiplex PCR if.falciparum,P.vivax and P.malariae) with an inbuilt positive control was developed and evaluated.In comparison with multiplex PCR,which showed the sensitivity and specificity of 99.36%(95%CI,98.11%-100.00%) and 100.00%(95%CI,100.00%-100.00%),the sensitivity and specificity of microscopy was 90.44%(95%CI,88.849-95.04%) and 99.22%(95% CI,97.71%-100.00%),and OptiMAL? was 93.58%(95%CI,89.75%-97.42%) and 97.69%(95%CI, 95.10%-100.00%).The efficiencies were 99.65%,95.10%and 95.45%for multiplex PCK.microscopy and OptiMAL?.respectively.Conclusions:Our results raise concerns over the overall sensitivities of microscopy and OptiMAL?,when compared to the multiplex PCR and thus stress the need for new molecular interventions in the accurate detection of the malarial parasites.This further highlights the fact that further developments are needed to improve the performance of rapid diagnostic tests at field level.Deepak Pakalapati Shilpi Garg Sheetal Middha Abhishek Kochar Amit Kumar Subudhi Boopathi Pon Arunachalam Sanjay Kumar Kochar Vishal Saxena Pareek RP Jyoti Acharya Dhanpat Kumar Kochar Ashis Das 2013Asian Pacific Journal of Tropical Medicine2013,6,5:3
6Load shedding strategy coordinated with storage device and D-STATCOM to enhance the microgrid stability显示文摘Recently microgrids have drawn a potential attraction by fulfilling the environmental demands and the increasing energy demands of the end-users. It is necessary to focus on various protection and control aspects of a microgrid. During the transition between the grid-following and grid-forming modes, the voltage and the frequency instability due to the power mismatch condition becomes the major point of concern. Therefore, the paper executes a frequency-active power and voltage-reactive power drooping control strategy for the precise power-sharing among the distributed power generators. Furthermore, to handle the power deficit scenarios and to maintain the system stability, a system independent and priority-based adaptive three-stage load shedding strategy is proposed. The sensitivity of the strategy depends on the system inertia and is computed according to the varying absolute rate-of-change-of-frequency. The strategy incorporates the operation of battery storage system and distributed static compensator (D-STATCOM) in the microgrid, to provide a reliable power supply to the customers for a considerable time instead of a sudden load shedding. The effectiveness of the proposed strategies is investigated on a scaled-down modified IEEE 13-bus microgrid system on the podium of MATLAB 2015b through the time-domain simulation.Sheetal Chandak Pritam Bhowmik Pravat Kumar Rout 2019Protection and Control of Modern Power Systems2019,4,1:3

8Dentinogenic ghost cell tumor: A case report显示文摘BACKGROUND Dentinogenic ghost cell tumor(DGCT) is an uncommon locally invasive odontogenic neoplasm. It is considered to be a solid variant of calcifying odontogenic cyst(COC). This tumor makes up for only 2%-14% of all COCs and less than 0.5% of all odontogenic tumors which owes to its rarity. The purpose of this paper was to describe a case of DGCT and the treatment adopted in our case,and to provide a review of this case in the indexed literature.CASE SUMMARY In this article, we discussed a case of 18 year old male who reported with a chief complaint of a recurrent swelling and dull aching pain in upper left back region of the jaw. Computed tomography scan was carried out which revealed hypodense lesion with a few hyperdense flecks within it suggesting the presence of calcification. On incisional biopsy, diagnosis of COC was given. After segmental resection of the lesion, histopathogically odontogenic epithelium was noted along with calcifications, ghost cells and dentinoid material. Special staining was done with van Gieson and it showed pink areas of dentinoid material and yellow colour represented ghost cells. Hence, amalgamation of careful clinical examination, use of advanced radiographic imaging and detailed histopathological examination confirmed the diagnosis of DGCT. The patient was followed up for one year and there was no recurrence of the lesion or signs of any residual tumor.CONCLUSION Radical treatment should be carried out along with mandatory long-term follow up in order to avoid recurrence in aggressive lesions.Sangeeta R Patankar Palak Khetan Sheetal K Choudhari Harshal Suryavanshi 2019World Journal of Clinical Oncology2019,10,4:2
9Selenium Alleviates Carbohydrate Metabolism and Nutrient Composition in Arsenic Stressed Rice Plants显示文摘This study reported the influence of selenium(Se)on carbohydrate composition and some related enzymes and nutrient compositions of arsenic(As)stressed rice plants.Rice plants of cultivar PR126 were grown on soil amended with As in a range of 25-100μmol/kg with and without 0.5 or 1.0 mg/kg Se.Total soluble sugars(TSS)and reducing sugars(RS)increased in leaves of As stressed plants at the tillering and grain filling stages whereas sucrose and starch contents showed the reverse trend.Se supplementation to As stressed plants further increased TSS and RS,and enhanced sucrose phosphate synthase activity in rice leaves,thus improving sucrose content and the tolerance to As stress of the plants.Se alone or in combination with As resulted in lower As accumulation in rice husk and grains,and the highest reduction was observed in Se applied at 1.0 mg/kg compared to the corresponding As treatments alone.As may limit the accumulations of Na,Mg,K,Ca,Fe,Zn and Mn in rice grains,which are essential for humans.Binary application of different combinations of As and Se protected the plants against As and increased the mineral content in rice grains.Addition of Se in As treated soil significantly alleviated As stress by enhancing grain yields compared to the corresponding As treatment.It is concluded that Se induced amelioration of the toxic impact of As in rice either by modulating carbohydrate composition and/or nutrient uptake is one of the mechanisms to alleviate As stress in plants.Sheetal BHADWAL Sucheta SHARMA 2022Rice science2022,29,4:2
10Neuropathy experienced by colorectal cancer patients receiving oxaliplatin: A qualitative study to validate the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity scale显示文摘BACKGROUND Although oxaliplatin is widely established as a standard treatment in colorectal cancer(CRC),oxaliplatin-induced neuropathy has emerged as a prominent doselimiting side effect associated with quality of life decrements.Ongoing monitoring and management of neuropathy is important for CRC patient quality of life and adherence to treatment.Therefore,a validated self-reported measure of neuropathy would aid in the management and assessment of oxaliplatininduced neuropathy in clinical practice and research.We sought to evaluate the content validity of the 13-item Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity subscale(FACT/GOGNtx)for CRC patients receiving oxaliplatin.AIM To understand the neuropathy experiences of CRC patients and assess content validity of the FACT/GOG-Ntx.METHODS Semi-structured concept elicitation and cognitive debriefing interviews were conducted with 31 CRC patients experiencing peripheral neuropathy from current or previous oxaliplatin treatment.Interview data were analyzed using a constant comparative approach,and data were mapped to the FACT/GOG-Ntx to assess content validity.RESULTS Mean age of the sample was 54(range 34-82).The sample was primarily Caucasian(84%)and consisted of nearly equal numbers of men and women.Participants described 28 unique neuropathy symptoms;hand tingling(experienced by 87%of respondents);feet tingling(81%);hand numbness(68%);and feet numbness(84%)were most frequently mentioned.Neuropathy symptoms occurring on the feet were most often identified as most bothersome by participants.Eleven of the 13 FACT/GOG-Ntx items exhibited moderate to strong evidence of content validity.Two items related to trouble hearing and ringing in the ears had weak support;however,these items represent severe neuropathy and could be useful for a patient reported outcome measure.CONCLUSION The FACT/GOG-Ntx represents the key neuropathy experiences of CRC patients treated with oxaliplatin.Karen Kaiser Madison Lyleroehr Sara Shaunfield Leilani Lacson Maria Corona Sheetal Kircher Malin Nittve David Cella 2020World Journal of Gastrointestinal Oncology2020,12,2:2
