1Techniques to resect the distal ureter in robotic/laparoscopic nephroureterectomy显示文摘Treatment of clinically-organ confined high grade urothelial carcinoma of the upper tract has historically comprised open nephroureterectomy,with the distal ureter and bladder cuff mobilized through a separate open pelvic incision.To decrease morbidity,urologists have increasingly adopted laparoscopy and robotics in performing nephroureterectomy.In many published series of laparoscopic nephroureterectomy,the distal ureter and bladder cuff are detached from the bladder endoscopically by a variation of the“pluck”technique,with the resulting bladder defect left to heal by prolonged indwelling urethral catheter drainage.While the distal ureter and bladder cuff can be excised laparoscopically,it does require advanced laparoscopic skills.With the wrist articulation and stereoscopic vision in robotic surgery,robotic nephroureterectomy(RNU)and bladder cuff excision can be performed in antegrade fashion to mimic the open technique together with the ability to intracorporeally close the bladder defect in a watertight,mucosa to mucosa fashion after excising the bladder cuff.In this review,we discuss the published minimally invasive techniques in resecting the distal ureter and bladder cuff during laparoscopic and RNU.Weil R.Lai Benjamin R.Lee 2016Asian Journal of Urology2016,3,3:6

3Investigation of confocal microscopy for differentiation of renal cell carcinoma versus benign tissue.Can an optical biopsy be performed?显示文摘Objective:Novel optical imaging modalities are under development with the goal of obtaining an“optical biopsy”to efficiently provide pathologic details.One such modality is confocal microscopy which allows in situ visualization of cells within a layer of tissue and imaging of cellular-level structures.The goal of this study is to validate the ability of confocal microscopy to quickly and accurately differentiate between normal renal tissue and cancer.Methods:Specimens were obtained from patients who underwent robotic partial nephrectomy for renal mass.Samples of suspected normal and tumor tissue were extracted from the excised portion of the kidney and stained with acridine orange.The stained samples were imaged on a Nikon E600 C1 Confocal Microscope.The samples were then submitted for hematoxylin and eosin processing and read by an expert pathologist to provide a gold-standard diagnosis that can later be compared to the confocal images.Results:This study included 11 patients,17 tissue samples,and 118 confocal images.Of the 17 tissue samples,10 had a gold-standard diagnosis of cancer and seven were benign.Of 118 confocal images,66 had a gold-standard diagnosis of cancer and 52 were benign.Six confocal images were used as a training set to train eight observers.The observers were asked to rate the test images on a six point scale and the results were analyzed using a web based receiver operating characteristic curve calculator.The average accuracy,sensitivity,specificity,and area under the empirical receiver operating characteristic curve for this study were 91%,98%,81%,and 0.94 respectively.Conclusion:This preliminary study suggest that confocal microscopy can be used to distinguish cancer from normal tissue with high sensitivity and specificity.The observers in this study were trained quickly and on only six images.We expect even higher performance as observers become more familiar with the confocal images.Michael C.Phung Andrew R.Rouse Jayce Pangilinan Robert C.Bell Erika R.Bracamonte Sharfuddeen Mashi Arthur F.Gmitro Benjamin R.Lee 2020Asian Journal of Urology2020,7,4:2
4On the dynamics in a transitional boundary layer显示文摘A model is presented to describe the dynamic physical processes that occur in a transitional boundary layer flow. The CS-solitons, the closed vortex, the secondary closed vortex and the chain of ring-like vortices are postulated to be the basic flow structures of the transitional boundary layer as well as the turbulent boundary layer. It is argued that the central features of transitional and developed turbulent boundary layer flows can be explained in terms of how the series vortices interact with each other, and with the CS-solitons. The physical process that leads to the regeneration of the new closed vortex along the border of the CS-soliton, as well as the processes of evolution of the vortices to high frequency vortices, is described. The model is supported by the important developments in a number of 'kernel' experiments, which illustrate both transitional and developed turbulent boundary layer. An important aspect of the model is that it has been formulated to be consistent with accepted rational mechanics concepts that are known to provide a proper physical description of other flows.C.B.LEE R.LEE 2001Communications in Nonlinear Science and Numerical Simulation2001,6,3:2

14First demonstration of an all-solid-state optical cryocooler显示文摘Solid-state optical refrigeration uses anti-Stokes fluorescence to cool macroscopic objects to cryogenic temperatures without vibrations.Crystals such as Yb3+-doped YLiF4(YLF:Yb)have previously been laser-cooled to 91 K.In this study,we show for the first time laser cooling of a payload connected to a cooling crystal.A YLF:Yb crystal was placed inside a Herriott cell and pumped with a 1020-nm laser(47 W)to cool a HgCdTe sensor that is part of a working Fourier Transform Infrared(FTIR)spectrometer to 135 K.This first demonstration of an all-solid-state optical cryocooler was enabled by careful control of the various desired and undesired heat flows.Fluorescence heating of the payload was minimized by using a single-kink YLF thermal link between the YLF:Yb cooling crystal and the copper coldfinger that held the HgCdTe sensor.The adhesive-free bond between YLF and YLF:Yb showed excellent thermal reliability.This laser-cooled assembly was then supported by silica aerogel cylinders inside a vacuum clamshell to minimize undesired conductive and radiative heat loads from the warm surroundings.Our structure can serve as a baseline for future optical cryocooler devices.Markus P.Hehlen Junwei Meng Alexander R.Albrecht Eric R.Lee Aram Gragossian Steven P.Love Christopher E.Hamilton Richard I.Epstein Mansoor Sheik-Bahae 2018Light(Science & Applications)2018,7,1:1
15入侵植物粗毛牛膝菊根际土壤和根系真菌群落会沿海拔扩散路径发生变化显示文摘与入侵植物相关的真菌群落可能会随着海拔发生变化,这可能会影响入侵植物的表现和入侵力。我们最近的研究表明,入侵植物粗毛牛膝菊(Galinsoga quadriradiata)的根系AMF侵染率随着海拔的升高而下降。然而,尚不清楚这是否与真菌群落沿海拔的变化相关。为此,我们采用高通量测序技术、功能分组和线性分析等方法,研究了秦巴山区的粗毛牛膝菊根际土壤和根系真菌群落组成与结构沿海拔的变化趋势。研究结果表明,粗毛牛膝菊根际土壤和根系真菌群落物种多样性和种类组成随海拔升高发生了显著变化。在根际土壤中真菌群落香农-威纳多样性指数随着海拔升高呈上升趋势,而在根系中则呈下降趋势。同时,在根际土壤中共生真菌的相对丰度随海拔高度没有发生显著变化,而在根系中呈下降趋势;在根际土壤中病原真菌的相对丰度随着海拔呈下降趋势,而在根系中呈上升趋势。这些研究结果暗示,该种在向研究区域高海拔地区入侵时,土壤共生真菌的供给并不会缺乏,但其与这些真菌之间建立并维持共生关系的能力降低了;在向高海拔扩张过程中,该种倾向于在根系中积累更多的病原真菌,而减少对共生真菌的依赖。这些研究结果说明,入侵植物与真菌群落之间的相互作用会沿着海拔梯度发生显著变化,植物地下部分与真菌的相互作用可能是我们理解外来种如何在高海拔环境中入侵成功的关键。Rui-Ling Liu Wen-Gang Zhang Benjamin R.Lee Gang Liu Xing-Jiang Song Xiao-Yan Chen Jia-Bin Zou Fang-Fang Huang Zhi-Hong Zhu 2023Journal of Plant Ecology2023,16,1:0

17Bacillary layer detachment presenting with posterior scleritis:case report显示文摘Background:Bacillary layer detachment(BALAD)is a phenomenon characterized by fluid accumulation at the myoid region of the inner photoreceptor segments identifiable on optical coherence tomography(OCT)imaging.This finding has been recently described in patients with diverse primary diagnoses which share the common feature of serous exudation in the posterior pole.However,thus far there have been very few reports in the literature of BALAD in patients with posterior scleritis.Case Description:A 16-year-old male presented with unilateral vision changes that acutely worsened overnight to significant unilateral vision loss.He was eventually diagnosed with idiopathic posterior scleritis with associated BALAD on OCT.Similar to other reported cases of BALAD,he experienced anatomic restoration of the outer retina followed by good visual recovery after treatment with high dose steroid,ultimately with complete recovery of both retinal anatomy and vision within 4 months.Conclusions:This case provides further evidence that posterior scleritis can be a cause of BALAD.The rapid presentation and excellent visual and anatomical outcome of this case is entirely consistent with known descriptions of BALAD in a variety of other conditions,further supporting the categorization of BALAD as an entity which retinal specialists should be able to recognize as distinct from other forms of intraretinal fluid,retinal detachment,and retinoschisis.Gregory W.Bligard Andrew R.Lee Lynn M.Hassman 2022Annals of Eye Science2022,,3:0
18Sex hormone-binding globulin impedes hepatocellular carcinoma growth via MERTK regulation显示文摘Sex hormone-binding globulin(SHBG),a crucial modulator of sex steroids in human blood,regulates androgen bioavailability and homeostasis.1 When androgen or AR signaling is known to be involved in the hepatocellular carcinoma(HCC)and SHBG plays an integral role in regulating the levels of bioavailable androgens,the concern whether SHBG might influence HCC onset or progression by modulating androgen action remains open.Sang R.Lee Eui-Ju Hong 2022Genes & Diseases2022,9,3:0
19GUI-Based DL-Network Designer for KISTI’s Supercomputer Users显示文摘With the increase in research on AI(Artificial Intelligence),the importance of DL(Deep Learning)in various fields,such as materials,biotechnology,genomes,and new drugs,is increasing significantly,thereby increasing the number of deep-learning framework users.However,to design a deep neural network,a considerable understanding of the framework is required.To solve this problem,a GUI(Graphical User Interface)-based DNN(Deep Neural Network)design tool is being actively researched and developed.The GUI-based DNN design tool can design DNNs quickly and easily.However,the existing GUI-based DNN design tool has certain limitations such as poor usability,framework dependency,and difficulty encountered in changing GUI components.In this study,a deep learning algorithm that solves the problem of poor usability was developed using a template to increase the accessibility for users.Moreover,the proposed tool was developed to save and share only the necessary parts for quick operation.To solve the framework dependency,we applied ONNX(Open Neural Network Exchange),which is an exchange standard for neural networks,and configured it such that DNNs designed with the existing deep-learning framework can be imported.Finally,to address the difficulty encountered in changing GUI components,we defined and developed the JSON format to quickly respond to version updates.The developed DL neural network designer was validated by running it with KISTI’s supercomputer-based AI Studio.Jaegwang Lee Jongsuk R.Lee Sunil Ahn 2021Computers, Materials & Continua2021,,11:0
20Prevalence of hyponatremia in acute medical admissions in tropical Asia Pacific Australia显示文摘Objective:To determine prevalence of hyponatremia in acute medical admissions in Northern Australasia.Methods:We studied 469 consecutive acute medical admissions to a hospital in Australia's Far North Queensland during the colder months of June and July 2012.Prevalence of hyponatremia and its relationship with gender,age,diagnosis and prognosis in acute medical admissions were investigated.Results:On admission,hyponatremia(plasma sodium<136 mmol/L)was present in 39.4%of patients,with mild(130—135 mmol/L),moderate(126-129 mmol/L)and severe?126 mmol/L)hyponatremia being present in 25.2%,10.7*and 3.6*respectively.Overall,adding together admission hyponatremia with that developing during admission,45.2%of patients were affected with 11.5%moderate hyponatremia cases and 4.1%severe ones.Hypokalemia and hyperkalemia were present in 17.0%and 18.1*,respectively.Overall,275/469 patients(58.6*)presented with an electrolyte abnormality.There were significant correlations of hyponatremia with age but not with gender and in-hospital mortality.Prevalence of hyponatremia was high across all diagnostic categories.Conclusions:The prevalence of hyponatremia appears to be high in the tropical North Australian population,being the highest prevalence reported amongst acute hospital admissions.The previously reported correlations with age and mortality do appear to hold good for this population with a high prevalence of electrolyte disorders.Further prospective analysis on a larger population in the area is needed to confirm our findings.Usman H.Malabu David Porter Venkat N.Vangaveti Monsur Kazi R.Lee Kennedy 2014Asian Pacific Journal of Tropical Medicine2014,7,1:0
