Background and study aims: We previously reported our discovery of a white opaque substance (WOS) that is opaque to endoscopic light inside the epithelium while using magnifying endoscopy (ME) to examine gastric epithelial neoplasia. Histopathologic analysis revealed that the WOS comprises minute lipid droplets (LDs) accumulated within the neoplastic epithelium. In addition, the WOS was found i...

AIM To examine the association between white opaque substance (WOS) and histologically verified lipid droplets in colorectal epithelial neoplasms. METHODS We reviewed colonoscopy records at our institution from 2014 to 2016 and identified cases of endoscopically or surgically resected colorectal epithelial neoplasms observed by magnifying narrow-band imaging (M-NBI) colonoscopy. Immunohistoch...

We review efficient grid-free random walk methods for solving boundary value problems for the linearized Poisson-Boltzmann equation (LPBE). First we introduce the “Walk On Spheres” (WOS) algorithm [1] for the LPBE. Based on this WOS algorithm, another, related, Monte Carlo algorithm is presented. This modified Monte Carlo method reinterprets the weights used in the original WOS algorithm as sur...

One of the hottest topics that emerged these days between the area of Internet and distrubted computing and the area of operating system is Web Operating System (WOS). The objective of WOS is to deliver the full benefit of the World Wide Web. The WOS will support geographically distributed, highly available, incrementally scalable, and dynamically reconfiguring applications. WOS will include me...

AIM To examine how effectively forwards citation searching with Web of Science (WOS) or Google Scholar (GS) identified evidence to support public health guidance published by the National Institute for Health and Care Excellence. METHOD Forwards citation searching was performed using GS on a base set of 46 publications and replicated using WOS. OUTCOMES WOS and GS were compared in terms of ...

BACKGROUND We conducted a comprehensive bibliometrics analysis to calculate the H, G, M, A and R indicators for all Iranian biomedical research centers (IBRCs) from the output of ISI Web of Science (WoS) and Scopus between 1991 and 2010. We compared the research performance of the research centers according to these indicators. METHODS This was a cross-sectional and descriptive-analytical stu...

The problem of optimal Weighted Order Statistics (WOS) filters design is first related to the optimal design in a larger class, called Variable Rank Order Statistics (VROS) filters, the results obtained p r e viding guidelines for the approach to be used in WOS filtering. Since adaptive methods applied directly to WOS filter models have to cope with a very ill conditioned problem, the adaptatio...

We compare the visibility and performance of Latin American and Caribbean (LAC) publications in the Core collection indexes included in the Web of Science (WoS) —Science Citation Index Expanded, Social Sciences Citation Index, and Arts & Humanities Citation Index—and the Scielo Citation Index (SciELO CI) which was integrated into the larger WoS platform in 2014. The purpose of this comparison i...

BACKGROUND AND STUDY AIMS The authors previously reported that the white opaque substance (WOS) in gastric epithelial neoplasia was caused by accumulation of lipid droplets by immunohistochemical and immunoelectron microscopic studies of adipophilin, which was recently identified and validated as a marker of lipid droplets. The aim of the current study was to investigate the characteristics of ...

In this study we compare the visibility and performance of Latin American and Caribbean (LAC) Science in terms of its presence in the core collection indexes included in the Web of Science (WoS) —Science Citation Index Expanded, Social Sciences Citation Index, and Arts & Humanities Citation Index—and the Scielo Citation Index (SciELO CI)—which was recently integrated into the WoS platform.
