Quantifying temporal dynamics of greenhouse gas emissions in lake mesocosms: Deployment of a low‐cost measurement system

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

open access: yesMacromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

Repeatability of Metabolic Imaging With Hyperpolarized Pyruvate: Back‐to‐Back Neuroimaging and Blood Analysis

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 13C MRI with hyperpolarized [1‐13C]pyruvate enables noninvasive imaging of metabolic pathways. Considering the high dose of pyruvate used in hyperpolarized 13C‐pyruvate studies, circulating 13C‐pyruvate and the resulting 13C‐lactate in plasma may influence subsequent pyruvate metabolism, yet the guidance on consecutive injections does ...

Exercise, exerkines, and muscle–brain crosstalk in Parkinson's disease

open access: yesNeuroprotection, EarlyView.
Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with motor and non‐motor symptoms, driven by dopaminergic loss and α‐synuclein accumulation. Beyond neurodegeneration, growing evidence highlights skeletal muscle health as a key determinant of prognosis, with sarcopenia and frailty contributing to greater disability, fall ...

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

open access: yesPolymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Construction of an O2‐responsive engineering bioreactor for enhanced indole‐3‐propionic acid production and deoxynivalenol detoxification

open access: yesResponsive Materials, EarlyView.
An oxygen‐responsive living bioreactor was engineered via interspecies protoplast fusion, converting oxygen from an inhibitory stress into a programmable signal for sustained indole‐3‐propionic acid (IPA) production. This genetically encoded bioreactor enables robust aerobic operation and therapeutic efficacy of deoxynivalenol detoxification in vivo ...
