1Node Coverage Algorithms in Wireless Sensor Networks Using Mobile Agents显示文摘This paper proposes fault tolerant algorithms for routing mobile agents in a single channel wireless sensor network which cover every node in the network. These algorithms use local knowledge (assume no knowledge of global deployment or topology, etc). We propose the algorithms and show mathematical analysis to support our claims. The paper ends with simulation studies and discussion of results.RAINA Manik KUMAR Subhas PATRO Ranjeet 2006自动化学报2006,32,6:9

3Lubiprostone used with polyethylene glycol in diabetic patients enhances colonoscopy preparation quality显示文摘AIM: To assess the additive effect of lubiprostone on the quality of colon preparation in diabetics given single-dosed polyethylene glycol electrolyte(PEG)for colonoscopy.METHODS:This was an investigator-initiated,singlecenter,single-blinded prospective trial comparing the efficacy of L+PEG to PEG alone on colon preparation quality in diabetics undergoing screening colonoscopy.The study was approved by our institution’s IRB.The PEG was given as a single-dose to address patientcompliance concerns voiced by our IRB with splitdosing.All patients received only clear liquids the day prior to colonoscopy.Experimental group(Grp L)received PEG+1 dose L 2 h prior to and 2 h after PEG completion.Control group(Grp C)received only PEG the evening prior to the colonoscopy.Patients were randomly assigned to one of the 2 groups.The endoscopist was blinded to which colon prep was given and all colonoscopies were complete.Upon colonoscopy completion,the endoscopist rated the colon prep-quality by a validated 5-point Likert scale(1-excellent to 5-inadequate).RESULTS:Sixty patients were enrolled in the study;30 Grp L and 30 Grp C.Overall,patients were excluded due to study non-completion in 12(41%)Grp L and 5(17%) Grp C,P=0.04.Average colon preparation score Grp L =2.47 and Grp C=3.00,P=0.09.Although this was not statistically significant,there was a trend towards improved colon prep in Grp L.Statistical significance may have been achieved if completion rates had been similar between both study groups.CONCLUSION:Use of 2-L capsules with PEG resulted in a trend towards improved colon prep over PEG alone in diabetic patients when given as a single-dose regimen.Erika Grigg Moonkyung C Schubert Joshua Hall Fadi Rahhal Dimple Raina Subbaramiah Sridhar Sherman M Chamberlain 2010World Journal of Gastrointestinal Endoscopy2010,2,7:5
4医务人员呼吸道感染影响因素的巢式病例对照研究显示文摘目的探索医务人员在院内感染呼吸道传染病的影响因素,针对性的提出院感防范重点及感染控制改进建议。方法本研究采用巢式病例对照研究的方法。选取北京市东城区和西城区的9家二级以上医院,将符合条件的医务人员作为一个队列,对其医疗行为进行为期一个月的观察。依据咽拭子病原学检测结粜削定研究对象的呼吸道感染状况,并将他们分为病例组和对照组。通过问卷调查了解并比较肼组人员在职、眦暴露与防护行为等方面的差异。数据分析应用STATA11.0软件完成,危险因素的分析采用非条件Logistic回归。结果共有481名医务人员完成本次研究,随访率为100%。在481名研究对象中有40例经实验室确诊为呼吸道感染,纳入病例组,其他441人纳入对照组。单因素分析显示,医院级别、工作科室、高危操作、接触病人后洗手等四个因素可能与医务人员发生呼吸道感染相关。多因素非条件logistic回归分析发现,共有2个因素进入回归方程,其中从事高危操作(OR=2.42,95%CI1.06~5.50)为发生呼吸道感染的危险因素,接触病人后洗手(OR=0.41,95%CI0.19—0.89)为保护性因素。结论为防止医务人员在院内感染呼吸道传染病,针对其危险因素所采取的干预措施亟待开展。张奕 Chandini Raina MacIntyre 杨鹏 Holly Seale 王小莉 刘文婷 Simon Cauchemez Neil Ferguson 王全意 2011国际病毒学杂志2011,18,5:4
5中国与澳大利亚医学教育培养模式的比较研究显示文摘中国医疗卫生体制正面临重大改革,医学教育也随之进行了快速调整,以满足我国卫生服务和医药卫生事业发展的需要。然而,医学教育体制的调整以及全国不同地区的学制设置的差异,导致我国医学教育学制和与之相对应学位的定义很难进行国际的同步比较,也使我国医学学位和学制很难被国际上许多国家教育部门所理解。结合澳大利亚高等医学教育的理论和实践经验,从招生、学制建设、课程设置和教学模式等方面,与中国的医学教育培养模式进行系统性对比和分析,为完善我国高等医学教育体系提供参考,更为我国医学教育体制与国外成熟体制间的相互参照奠定基础。莫佳瑜 孔宪明 王春鸣 Raina MacIntyre Joanne Travaglia Chinthaka Balasooriya 2015中华医学教育探索杂志2015,14,1:3
6Hemodynamic monitoring in heart failure and pulmonary hypertension: From analog tracings to the digital age显示文摘Hemodynamic monitoring has long formed the cornerstone of heart failure(HF) and pulmonary hypertension diagnosis and management. We review the long history of invasive hemodynamic monitors initially using pulmonary artery(PA) pressure catheters in the hospital setting, to evaluating the utility of a number of implantable devices that can allow for ambulatory determination of intracardiac pressures. Although the use of indwelling PA catheters has fallen out of favor in a number of settings, implantable devices have afforded clinicians an opportunity for objective determination of a patient's volume status and pulmonary pressures. Some devices, such as the CardioM EMS and thoracic impedance monitors present as part of implantable cardiac defibrillators, are supported by a body of evidence which show the potential to reduce HF related morbidity and have received regulatory approval, whereas other devices have failed to show benefit and, in some cases, harm. Clearly these devices can convey a considerable amount of information and clinicians should start to familiarize themselves with their use and expect further development and refinement in the future.Ryan Davey Amresh Raina 2016World Journal of Transplantation2016,6,3:3
7Double-vessel verylate stent thrombosis following Resolute Onyx zotarolimus eluting stents implantation in an octogenarian显示文摘Compared with bare-metal stents (BMS),drug-eluting stems (DES)have shown better clinical outcomes for pa- tients undergoing percutaneous coronary intervention (PCI) by inhibition of neo-intirnal hyperplasia.[1]However,early- generation DES produced late thrombotic events,more than l-year,by delaying arterial healing of stented vessels,[2-5] New-generation DES have been developed'with thinner stent struts,more biocompatible polymer coatings for drug release,and a variety of antiproliferative agents with similar or superior anti-restenotic efficacy.[6]This development has led to a significant improvement in the efficacy and safety of new-generation DES,and consistently lower rates of very late stent thrombosis (VLST).[7,8]In fact,use of new-ge- neration DES is the standard treatment in contemporary PCI practice.[9]George Kassimis Tushar Raina 2018Journal of Geriatric Cardiology2018,15,10:2
8Silibinin and colorectal cancer chemoprevention:a comprehensive review on mechanisms and efficacy显示文摘Globally,the risk of colorectal cancer(CRC) as well as the incidence of mortality associated with CRC is increasing.Thus,it is imperative that we look at alternative approaches involving intake of non-toxic natural dietary/non-dietary agents,for the prevention of CRC.The ultimate goal of this approach is to reduce the incidence of pre-neoplastic adenomatous polyps and prevent their progression to more advanced forms of CRC,and use these natural agents as a safe intervention strategy during the clinical course of this deadly malignancy.Over the years,pre-clinical studies have shown that silibinin(a flavonolignan isolated from the seeds of milk thistle,Silybum marianum) has strong preventive and therapeutic efficacy against various epithelial cancers,including CRC.The focus of the present review is to provide a comprehensive tabular summary,categorically for an easy accessibility and referencing,pertaining to the efficacy and associated mechanisms of silibinin against CRC growth and progression.Komal Raina Sushil Kumar Deepanshi Dhar Rajesh Agarwal 2016The Journal of Biomedical Research2016,30,6:2

10Palliative care for acute kidney injury patients in the intensive care unit显示文摘Patients with acute kidney injury(AKI) in the intensive care unit(ICU) are often suitable for palliative care due to the high symptom burden. The role of palliative medicine in this patient population is not well defined and there is a lack of established guidelines to address this issue. Because of this,patients in the ICU with AKI deprived of the most comprehensive or appropriate care. The reasons for this are multifactorial including lack of palliative care training among nephrologists. However,palliative care in these patients can help alleviate symptoms,improve quality of life,and decrease suffering. Palliative care physicians can determine the appropriateness and model of palliative care. In addition to shared decision-making,advance directives should be established with patients early on,with specific instructions regarding dialysis,and those advance directives should be respected.Vinod Krishnappa William Hein Daniel DelloStritto Mona Gupta Rupesh Raina 2018World Journal of Nephrology2018,7,8:2
11Oxygen Electrocatalysis on Mixed-Metal Oxides/Oxyhydroxides:From Fundamentals to Membrane Electrolyzer Technology显示文摘CONSPECTUS:Catalyzing the oxygen evolution reaction(OER)is important for key energy-storage technologies,particularly water electrolysis and photoelectrolysis for hydrogen fuel production.Under neutral-to-alkaline conditions,first-row transitionmetal oxides/(oxy)hydroxides are the fastest-known OER catalysts and have been the subject of intense study for the past decade.Critical to their high performance is the intentional or accidental addition of Fe to Ni/Co oxides that convert to layered(oxy)hydroxide structures during the OER.Unraveling the role that Fe plays in the catalysis and the molecular identity of the true“active site”has proved challenging,however,due to the dynamics of the host structure and absorbed Fe sites as well as the diversity of local structures in these disordered active phases.In this Account,we highlight our work to understand the role of Fe in Ni/Co(oxy)hydroxide OER catalysts.We first discuss how we characterize the intrinsic activity of the first-row transition-metal(oxy)hydroxide catalysts as thin films by accounting for the contributions of the catalyst-layer thickness(mass loading)and electrical conductivity as well as the underlying substrate’s chemical interactions with the catalyst and the presence of Fe species in the electrolyte.We show how Fe-doped Ni/Co(oxy)hydroxides restructure during catalysis,absorb/desorb Fe,and in some cases degrade or regenerate their activity during electrochemical testing.We highlight the relevant techniques and procedures that allowed us to better understand the role of Fe in activating other first-row transition metals for OER.We find several modes of Fe incorporation in Ni/Co(oxy)hydroxides and show how those modes correlate with activity and durability.We also discuss how this understanding informs the incorporation of earthabundant transition-metal OER catalysts in anion-exchange-membrane water electrolyzers(AEMWE)that provide a locally basic anode environment but run on pure water and have advantages over the more-developed proton-exchange-membrane water electrolyzers(PEMWE)that use platinum-group-metal(PGM)catalysts.We outline the key issues of introducing Fe-doped Ni/Co(oxy)hydroxide catalysts at the anode of the AEMWE,such as the oxidative processes triggered by Fe species traveling through the polymer membrane,pH-gradient effects on the catalyst stability,and possibly limited catalyst utilization in the compressed stack configuration.We also suggest possible mitigation strategies for these issues.Finally,we summarize remaining challenges including the long-term stability of Fe-doped Ni/Co(oxy)hydroxides under OER conditions and the lack of accurate models of the dynamic active surface that hinder our understanding of,and thus ability to design,these catalysts.Raina A.Krivina Yingqing Ou Qiucheng Xu Liam P.Twight T.Nathan Stovall Shannon W.Boettcher 2021Accounts of Materials Research2021,2,7:2
