Lack of Usefulness of Literature‐Based Helicobacter pylori Resistance Data for Predicting First‐Line Empirical Treatment Effectiveness in the European Registry on H. pylori Management (Hp‐EuReg)

open access: yesHelicobacter, Volume 31, Issue 6, November/December 2026.
ABSTRACT Background Helicobacter pylori (H. pylori) infection causes gastritis, peptic ulcer disease, and gastric cancer. Without an effective vaccine, eradication therapy remains crucial. However, increasing antibiotic resistance compromises treatment effectiveness.

Ion Beam Experiments to Emulate Nuclear Fusion Environment on Structural Materials at CMAM

open access: yes, 2020
One of the major problems not only in nuclear fusion but in all the fields that have to face irradiation damage is to predict the microstructural evolution of all the features that are involved in the good response of the material. In the case of nuclear fusion, it is well known that structural materials that will be a fundamental piece in the future ...

The Role of Lightning in Atmospheric Chemistry

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...
