Multicenter prospective study on the histological diagnosis of gastric cancer by narrow band imaging-magnified endoscopy with and without acetic acid

Endoscopy International Open, 2019
Background and study aims The usefulness of endoscopy for diagnosing histological type remains unclear. This study aimed to examine the diagnostic accuracy of white light endoscopy (WLE), magnified endoscopy with narrow band imaging (NBI-ME), and NBI-ME ...

Narrow-band imaging (NBI) for improving the assessment of vocal fold leukoplakia and overcoming the umbrella effect

PLoS ONE, 2017
Background It is crucial to find a balance between functional and oncological outcome when choosing an adequate method for the management of vocal fold leukoplakia. Therefore, a detailed examination is a milestone in the decision-making process.

Modelling of NBI ion wall loads in the W7-X stellarator

Nuclear Fusion, 2018
It is known that NBI ion losses may pose a problem to the Wendelstein 7-X first wall, but the so-far utilized wall models had insufficient details for reproducing the locations and magnitude of the hot-spots.

Sustained pharmacodynamic effects of S‐ketamine on cortical excitability and resting‐state brain activity: A randomized, placebo‐controlled trial

British Journal of Clinical Pharmacology, EarlyView.
Aims This study aimed to investigate a set of pharmacodynamic biomarkers reflecting acute, delayed and sustained central nervous system effects of S‐ketamine, used as a tool compound for rapid‐acting antidepressant activity, with the goal of informing biomarker strategies for delayed antidepressant effects.

Effect of adding acetic acid when performing magnifying endoscopy with narrow band imaging for diagnosis of Barrett’s esophageal adenocarcinoma

Endoscopy International Open, 2022
Background and study aims Magnifying endoscopy with narrow band imaging (M-NBI) was developed to diagnose Barrett’s esophageal adenocarcinoma (BEA); however, this method remains challenging for inexperienced endoscopists.

Heat Load Mitigation Studies in the W7‐X Stellarator Experiment

Contributions to Plasma Physics, EarlyView.
ABSTRACT During the experiments at the stellarator Wendelstein 7‐X (W7‐X) with fully water‐cooled plasma‐facing components (PFC), including carbon‐fiber composite (CFC) divertor targets with a thermal load capability of 10 MW/m2, high performance was achieved.

Constructing Interface‐Enhanced S‐Heterojunctions Via Surface Functionalization Strategies to Improve Photocatalytic Hydrogen Production Efficiency in Inorganic/Organic Composite Systems

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surface in situ growth strategy was employed to fabricate a COF/TiO2 S‐scheme heterojunction with enhanced interfacial forces. This enhanced interfacial heterojunction significantly improved photocatalytic hydrogen production capacity. S‐scheme heterojunctions play a crucial role in enhancing charge‐carrier separation efficiency and redox capability.

Endocytoscopy with NBI has the potential to correctly diagnose diminutive colorectal polyps that are difficult to diagnose using conventional NBI

Endoscopy International Open, 2020
Background and study aims Real-time diagnosis of colorectal polyps is needed to prevent unnecessary resection of benign polyps. The vessels in hyperplastic polyps sometimes mimic the characteristic meshed capillary network of neoplastic lesions on non ...

SUDEP and mortality in developmental and epileptic encephalopathies: A meta‐analysis of randomized clinical trials and extension studies

Epilepsia, EarlyView.
Abstract Objective Developmental and epileptic encephalopathies (DEEs) are associated with high premature mortality and increased risk of sudden unexpected death in epilepsy (SUDEP). However, epidemiological data remain limited, particularly for specific syndromes such as Dravet syndrome (DS), Lennox–Gastaut syndrome (LGS), and infantile epileptic ...
