Polyp Detection, Characterization, and Management Using Narrow-Band Imaging with/without Magnification [PDF]

Clinical Endoscopy, 2015
Narrow-band imaging (NBI) is a new imaging technology that was developed in 2006 and has since spread worldwide. Because of its convenience, NBI has been replacing the role of chromoendoscopy. Here we review the efficacy of NBI with/without magnification

Neobavaisoflavone Inhibits Melanogenesis through the Regulation of Akt/GSK-3β and MEK/ERK Pathways in B16F10 Cells and a Reconstructed Human 3D Skin Model

Molecules, 2020
Previous studies have confirmed the anti-melanogenic effect of the aerial part of Pueraria lobata, however, due to its inherent color, P. lobata has limited commercial use. In this study, an extract (GALM-DC) of the aerial part of P.

Influence of ICRF-NBI synergy on fast ion distribution and plasma performance in second harmonic heating experiments with deuterium NBI at EAST

Nuclear Fusion, 2023
Ion Cyclotron Range of Frequencies (ICRF) heating and Neutral Beam Injection (NBI) can have synergy due to the acceleration of NBI beam ions by ICRF wave fields at their harmonics.

White Light, Magnifying Endoscopy, Endocytoscopy, and Artificial Intelligence in Diagnosis of Early Colorectal Cancer: A Comparative Study. [PDF]

DEN Open
ABSTRACT Objectives Early detection of colorectal cancer is critical for improving prognosis. However, assessing invasion depth—distinguishing between superficial cancer (T1a) and deep submucosal invasive cancer (T1b)—remains challenging. Recently, artificial intelligence (AI)‐assisted computer‐aided diagnosis (CADx) systems have been introduced to ...

Use of narrow band imaging in a group endoscopy practice

Endoscopy International Open, 2013
Background and study aim: Narrowband imaging (NBI) is an enhanced endoscopic optical technique which filters white light and accentuates imaging of the mucosal vasculature. Potential clinical applications of NBI include endoscopic inspection of Barrett’s

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties [PDF]

, 2016
The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains roughly as in the L-mode ...

Impact of thyroid cancer on the cancer risk in patients with non-alcoholic fatty liver disease or dyslipidemia

Scientific Reports, 2023
The raised prevalence of obesity has increased the incidence of obesity-related metabolic diseases such as dyslipidemia (DL) and non-alcoholic fatty liver disease (NAFLD), along with the development and progression of various types of cancer, including ...

Requirements and modelling of fast particle injection in RFX-mod tokamak plasmas [PDF]

, 2017
The planned upgrade of the RFX-mod device is a good opportunity to widen the operational space of the machine, in both RFP and tokamak configurations. Installation of a power neutral beam injector is also envisaged and a NB system compatible with RFX-mod,

Acetic Acid Enhanced Narrow Band Imaging for the Diagnosis of Gastric Intestinal Metaplasia. [PDF]

PLoS ONE, 2017
Gastric intestinal metaplasia (GIM) is a precancerous lesion of the stomach. The detection of GIM using conventional white-light endoscopy (WLE) is difficult. In this study, we determined whether acetic acid-enhanced narrow band imaging (AA-NBI) improves
