AIM To understand the influence of chronic kidney disease(CKD) on mortality, need for transfusion and rebleeding in gastrointestinal(GI) bleeding *** A systematic search was conducted in three databases for studies on GI bleeding patients with CKD or endstage renal disease(ESRD) with data on outcomes of mortality, transfusion requirement, rebleeding rate and length of hospitalization(LOH). Calculations were performed with Comprehensive Meta-Analysis software using the random effects model. Heterogeneity was tested by using Cochrane's Q and I2 statistics. Mean difference(MD) and OR(odds ratio) were ***1063 articles(EMBASE: 589; PubM ed: 459; Cochrane: 15) were found in total. 5 retrospective articles and 1 prospective study were available for analysis. These 6 articles contained data on 406035 patients, of whom 51315 had impaired renal function. The analysis showed a higher mortality in the CKD group(OR = 1.786, 95%CI: 1.689-1.888, P < 0.001) and the ESRD group(OR = 2.530, 95%CI: 1.386-4.616, P = 0.002), and a rebleeding rate(OR = 2.510, 95%CI: 1.521-4.144, P < 0.001) in patients with impaired renal function. CKD patients required more unit red blood cell transfusion(MD = 1.863, 95%CI: 0.812-2.915, P < 0.001) and spent more time in hospital(MD = 13.245, 95%CI: 6.886-19.623, P < 0.001) than the *** ESRD increases mortality, need for transfusion, rebleeding rate and LOH among GI bleeding patients. Prospective patient registries and observational clinical trials are crucially needed.

在19世纪,欧洲文学成为宣扬民族认同和忠诚的一种有力手段。而文学史作为一门学科被建立起来,其目的即是要有利于构建某种国族身份。然而,欧洲遭受了民族主义的一系列灾难性后果;文学研究却在小心翼翼地尝试着重申其在构建民族国家中的任务。本文最后将讨论一些国际性的、以多种语言编辑的学术杂志。这些杂志在一定程度上暗示了文学研究中反传统因素的存在。这种反传统将在全球化的时代为非民族主义方法奠定基础。

Journal of Applied Mathematics and Physics 2023年第1期11卷 147-157页

作者： ramon Carbó-Dorca Institut de Química Computacional Universitat de Girona Girona Spain Ronin Institute Spain

The definition of Collatz Operator, the mathematical avatar of the Collatz Algorithm, permits the transformation of the Collatz conjecture, which is delineated over the whole natural number set, into an equivalent inference restricted to the odd prime number set only. Based on this redefinition, one can describe an empirical-heuristic proof of the Collatz conjecture.

Acute pancreatitis (AP) is a serious inflammatory disease with rising incidence both in the adult and pediatric populations. It has been shown that mitochondrial injury and energy depletion are the earliest intracellular events in the early phase of AP. Moreover, it has been revealed that restoration of intracellular ATP level restores cellular functions and defends the cells from death. We have recently shown in a systematic review and meta-analysis that early enteral feeding is beneficial in adults; however, no reviews are available concerning the effect of early enteral feeding in pediatric AP. In this minireview, our aim was to systematically analyse the literature on the treatmentof acute pediatric pancreatitis. The preferred reporting items for systematic review(PRISMA-P) were followed, and the question was drafted based on participants, intervention, comparison and outcomes: P: patients under the age of twenty-one suffering from acute pancreatitis; I: early enteral nutrition (per os and nasogastric- or nasojejunal tube started within 48 h); C: nil per os therapy; O: length of hospitalization, need for treatment at an intensive care unit, development of severe AP, lung injury (including lung oedema and pleural effusion), white blood cell count and pain score on admission. Altogether, 632 articles (Pub Med: 131; EMBASE: 501) were found. After detailed screening of eligible papers, five of them met inclusion criteria. Only retrospective clinical trials were available. Due to insufficient information from the authors, it was only possible to address length of hospitalization as an outcome of the study. Our mini-meta-analysis showed that early enteral nutrition significantly(SD = 0.806, P = 0.034) decreases length of hospitalization compared with nil per os diet in acute pediatric pancreatitis. In this minireview, we clearly show that early enteral nutrition, started within 24-48 h, is beneficial in acute pediatric pancreatitis. Prospective studies and better pres

地形数据的质量(精度和分辨率)影响着地球科学的研究水平。Li DAR测量是目前获取高分辨率地形数据的有效技术方法之一,但是其高昂的测量成本和相对复杂的后期数据处理限制了Li DAR技术的大众化应用。近年来,一种被称为Sf M(Structure from Motion)的适合大众化使用的新的高精度3维地形数据获取技术开始引起人们的注意。这种新型数字摄影测量技术可以利用高效的图像特征匹配算法从多视角照片中提取重叠区域的3维地形数据。由于Sf M技术仅需要目标物体的照片,而且对相机拍摄位置、图像尺度及拍摄焦距没有要求,因此利用简单测量平台采集地面照片就可以获取高质量的3维地形数据。与Li DAR技术相比,大大降低了获取高精度数据的成本,使得高精度3维地形数据的使用大众化。文中介绍了Sf M技术的基本原理和流程,展示了Sf M技术获取高精度3维地形数据的简单而有效的特性,特别适合于植被稀少的区域。文中利用近千米高空拍摄的、具有约70%重叠度的一套随Li DAR飞行采集的数字航空照片生成具有真彩色的高密度Sf M点云数据,点密度高达25.5个/m2,可生成分辨率0.2m的DEM(数字高程模型)。对比相同区域的LiDAR点云数据,统计分析表明58.3%的Li DAR数据与Sf M数据的垂直偏差<0.1m,88.3%的Li DAR数据的垂直偏差<0.2m;而且发现不同地貌的Sf M数据精度存在差异,平缓地形的Sf M数据精度高于陡峭地形的Sf M数据精度。文中还介绍了以氦气球作为拍摄平台的Sf M测量系统,可以快捷地获取高精度的3D地形数据和正射影像,比目前常用的差分GPS测量具有更高的效率和数据精度。

作者： Péter Gyula Antal Róbert Szipcs Research Institute for Solid State Physics and Optics P.O.Box 49H-1525 BudapestHungary

We show that absorbed and stored electromagnetic energy are proportional to the reflection group delay in highly reflective dispersive dielectric mirrors over the high-reflectivity band. Our theoretical considerations are verified by numerical simulations performed on different dielectric mirror structures. The revealed pro- portionality between group delay and absorbed energy sets constraint on the application of ultrabroadband and/or dispersive dielectric mirrors in broadband or widely tunable, high-power laser systems.

Photoluminescent Tb^(3+)-based metal-organic framework as a sensor for detection of methanol in ethanol fuel

引用

Journal of Rare Earths 2019年第3期37卷 225-231页

作者： ramon R.F.Fonseca Rafael D.L.Gaspar Ivo M.Raimundo Jr. Priscilla P.Luz Department of Chemistry Federal University of Espírito Santo Institute of Chemistry University of Campinas

The sensing capability of a Tb^(3+)-metal-organic framework, based on its photoluminescence, was used for detection of methanol in ethanol fuel. It was synthesized using terbium and trimesic acid as a metal ion center and ligand, respectively. Powder X-ray diffraction, infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy were employed to characterize the synthesized MOF-76 structural features. According to the results, MOF-76 was successfully obtained with minor synthetic modification and its activated form(named TbTMA) was tested as a sensor for methanol. Tb^(3+) luminescence intensity increases as the methanol concentration in ethanol fuel also increases and the water content does not affect this response. Our findings indicate TbTMA as an appropriate sensor for evaluating ethanol fuel adulteration by methanol addition above the allowed limit.

Asian Journal of Andrology 2015年第3期17卷 511-512页

作者： Ana Avargues ramon Rogel Enrique Broseta Saturnino Lujan Jesus A Betancourt Gonzalo Morales Francisco Boronat Department of Urology University and Polytechnic Hospital La Fe Valencia 46026 Spain

Dear Editor, Polyorchidism refers to the presence of more than two testicles. Blasius described it for the first time in 1670 as an incidental finding in an autopsy, while Lane was the one who performed the first histological description of a supernumerary testis in 1895.1,2 Before imaging diagnosis techniques, this condition could only be verified under surgical exploration. Nowadays, current imaging techniques have increased the number of diagnosis of this anatomical variation. On the other hand, there is still a certain group of physicians who use histological analysis as the unioue way to diagnosis.

BACKGROUND Obesity rates have increased sharply in recent decades. As there is a growing number of cases in which acute pancreatitis(AP) is accompanied by obesity, we found it clinically relevant to investigate how body-mass index(BMI) affects the outcome of the *** To quantify the association between subgroups of BMI and the severity and mortality of *** A meta-analysis was performed using the Preferred Reporting Items for Systematic Review and Meta-Analysis(PRISMA) Protocols. Three databases(PubMed, EMBASE and the Cochrane Library) were searched for articles containing data on BMI, disease severity and mortality rate for AP. Englishlanguage studies from inception to 19 June 2017 were checked against our predetermined eligibility criteria. The included articles reported all AP cases with no restriction on the etiology of the disease. Only studies that classified AP cases according to the Atlanta Criteria were involved in the severity analyses. Odds ratios(OR) and mean differences(MD) were pooled using the random effects model with the DerSimonian-Laird estimation and displayed on forest plots. The meta-analysis was registered in PROSPERO under number *** A total of 19 articles were included in our meta-analysis containing data on 9997 patients. As regards severity, a subgroup analysis showed a direct association between AP severity and BMI. BMI 25 had an almost three-fold increased risk for severe AP in comparison to normal BMI(OR = 2.87, 95%CI: 1.90-4.35, P < 0.001). Importantly,the mean BMI of patients with severe AP is higher than that of the non-severe group(MD = 1.79, 95%CI: 0.89-2.70, P < 0.001). As regards mortality, death rates among AP patients are the highest in the underweight and obese subgroups. A BMI < 18.5 carries an almost two-fold increase in risk of mortality compared to normal BMI(OR = 1.82, 95%CI: 1.32-2.50, P < 0.001). However, the chance of mortality
