Early life stress and disruption of the ageing trajectory in female rats: Insights into the origins and mechanisms underlying the risk of hypertension

open access: yesExperimental Physiology, EarlyView.
Abstract Menopause increases the risk of hypertension in women, yet the factors contributing to this important change remain unclear. Because early life stress has persistent and sex‐specific consequences on health, we hypothesized that ageing reveals the latent effects of neonatal maternal separation (NMS) on cardiovascular homeostasis in female rats.

High Score of ELST‐Blue in Endoscopic Ultrasonography Strain Elastography May Provide a High Risk Group of Early Chronic Pancreatitis with the Reduction of Apolipoprotein A2‐i Index

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background To evaluate the usefulness of the ELST‐blue score to explore its potential application in identifying high‐risk groups for early chronic pancreatitis (ECP) through reflecting on pancreatic elasticity and the reduction of pancreatic function, and we tried to demonstrate whether the ELST‐blue score was significantly associated with ...

Functionalization of amorphous nitrogenated carbon thin film electrodes for improved detection of cadmium vs. copper cations [PDF]

open access: yes, 2015
International audienceThe specificity of a sensor relative to specific cations can be modified by functionalization of amorphous nitrogenated carbon thin film (a-C:Nx) electrodes. This surface modification was performed through the reduction of diazonium

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.
