| 2 | Antralization at the edge of proximal gastric ulcers:Does Helicobacter pylori infection play a role?显示文摘AIM: To determine the prevalence of antralization at the edge of proximal gastric ulcers, and the effect ofH. pylori eradication on the mucosal appearances.
METHODS: Biopsies were taken from the antrum, body and the ulcer edge of patients with benign proximal gastric ulcers before and one year after treatment. Gastric mucosa was classified as antral, transitional or body type.H. pylori positive patients receivedeither triple therapy, or omeprazole.
RESULTS: Patients with index ulcers in the incisura, body or fundus (n=116) were analyzed. Antral-type mucosa was more prevalent at the ulcer edge inH. pylori-positive patients thanH.pylori-negative patients (93% vs 60%, OR=8.95,95%CI: 2.47-32.4, P=0.001). At one year, there was a significant reduction in the prevalence of antralization (from 93 % to 61%, P=0.004) at the ulcer edge in patients with H. pyloribeing eradicated. However, there was no difference in the prevalence of antralization at the ulcer edge in those with persistent infection.
CONCLUSION: H. pylori infection is associated with antralization at the edge of proximal gastric ulcers, which may be reversible in some patients after eradication of the infection. | Harry Hua-Xinag Xia Shiu Kum Lam Wai Man Wong Wayne Hsing Cheng Hu Kam Chuen Lai Sau Hing Wong Suet Yi Leung Siu Tsan Yuen Nicholas A.Wright Benjamin Chun-Yu Wong | 2003 | World Journal of Gastroenterology2003,9,6: | 2 |

| 7 | COMPARISON OF OPTICAL POLARIMETRY AND DIFFUSION TENSOR MR IMAGING FOR ASSESSING MYOCARDIAL ANISOTROPY显示文摘We have recently proposed an optical method for assessing heart structure that uses polarized light measurement of birefringence as an indicator of tissue anisotropy.The highly aligned nature of healthy cardiac muscle tissue has a detectable effect on the polarization of light,resulting in a measurable phase shift(“retardance”).When this organized tissue structure is perturbed,for example after cardiac infarction(heart attack),scar tissue containing disorganized collagen is formed,causing a decrease in the measured retardance values.However,these are dependent not only on tissue anisotropy,but also on the angle between the tissue’s optical anisotropy direction and the beam interrogating the sample.To remove this experimental ambiguity,we present a method that interrogates the sample at two different incident beam angles,thus yielding enough information to uniquely determine the true magnitude and orientation of the tissue optical anisotropy.We use an infarcted porcine heart model to compare these polarimetryderived anisotropy metrics with those obtained with diffusion tensor magnetic resonance imaging(DT-MRI).The latter yields the anisotropy and the direction of tissue water diffusivity,providing an independent measure of tissue anisotropy.The optical and MR results are thus directly compared in a common ex vivo biological model of interest,yielding reasonable agreement but also highlighting some technique-specific differences. | MARIKA A.WALLENBURG MIHAELA POP MICHAEL F.G.WOOD NIRMALYA GHOSH GRAHAM A.WRIGHT I.ALEX VITKIN | 2010 | Journal of Innovative Optical Health Sciences2010,3,2: | 0 |
| 8 | 曲线拟合法的Octave应用显示文摘天线的问题
我们开始为踏青做准备的时候已经有点晚了,才刚刚把40米CW天线竖立起来。我们用熟知的468/f(MHz)公式将其缩减到了7.050MHz,并在天线中央到操作地点之间串起了一条450Q的窗口线路。在连接无线电收发机之前,我们要用天线分析器对装置进行检查。可结果怎么会是这样?分析器告诉我们,天线的共振频率大约为7.23MHz。我们哪里弄错了?我们跑到80m波段的操作地点, | Maynard A.Wright 苏健 | 2012 | 电子制作2012,20,5: | 0 |
| 9 | A database of experimentally measured lithium solid electrolyte conductivities evaluated with machine learning显示文摘The application of machine learning models to predict material properties is determined by the availability of high-quality data.We present an expert-curated dataset of lithium ion conductors and associated lithium ion conductivities measured by a.c.impedance spectroscopy.This dataset has 820 entries collected from 214 sources;entries contain a chemical composition,an expert-assigned structural label,and ionic conductivity at a specific temperature(from 5 to 873°C).There are 403 unique chemical compositions with an associated ionic conductivity near room temperature(15–35°C).The materials contained in this dataset are placed in the context of compounds reported in the Inorganic Crystal Structure Database with unsupervised machine learning and the Element Movers Distance.This dataset is used to train a CrabNet-based classifier to estimate whether a chemical composition has high or low ionic conductivity.This classifier is a practical tool to aid experimentalists in prioritizing candidates for further investigation as lithium ion conductors. | Cameron J.Hargreaves Michael W.Gaultois Luke M.Daniels Emma J.Watts Vitaliy A.Kurlin Michael Moran Yun Dang Rhun Morris Alexandra Morscher Kate Thompson Matthew A.Wright Beluvalli-Eshwarappa Prasad Frédéric Blanc Chris M.Collins Catriona A.Crawford Benjamin B.Duff Jae Evans Jacinthe Gamon Guopeng Han Bernhard T.Leube Hongjun Niu Arnaud J.Perez Aris Robinson Oliver Rogan Paul M.Sharp Elvis Shoko Manel Sonni William J.Thomas Andrij Vasylenko Lu Wang Matthew J.Rosseinsky Matthew S.Dyer | 2023 | npj Computational Materials2023,,1: | 0 |
