The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

open access: yesCarbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

open access: yesDrug Testing and Analysis, EarlyView.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Charting Water‐in‐Natural‐Salt (WiNS) Electrolytes. Part I: Effect of Anion's Alkyl Tail Length

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
At 20 m, potassium carboxylates from formate to butyrate reveal anion tail‐controlled nanostructure. SAXS shows a pre‐peak shifting to lower q with chain length. Molecular dynamics reproduces S(q) and attributes it to concentration fluctuations forming bicontinuous segregation.

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...
