Adaptive evolutionary strategy coupled with an optimized biosynthesis process for the efficient production of pyrroloquinoline quinone from methanol

open access: yesBiotechnology for Biofuels and Bioproducts, 2023
Background Pyrroloquinoline quinone (PQQ), a cofactor for bacterial dehydrogenases, is associated with biological processes such as mitochondriogenesis, reproduction, growth, and aging.

Gadolinium Pollution—A Future Forward Perspective on Human and Environmental Impact

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1660-1670, March 2026.
ABSTRACT The widespread use of gadolinium‐based contrast agents (GBCAs) in magnetic resonance imaging (MRI) has been instrumental in enhancing diagnostic capabilities. However, the potential environmental and human health impacts of gadolinium pollution have become a growing concern.

Emission Trading Systems and the Optimal Technology Mix [PDF]

open access: yes, 2011
Cap and trade mechanisms enjoy increasing importance in environmental legislation worldwide. The most prominent example is probably given by the European Union Emission Trading System (EU ETS) designed to limit emissions of greenhouse gases, several ...

Nacre-inspired magnetically oriented micro-cellulose fibres/nano-hydroxyapatite/chitosan layered scaffold enhances pro-osteogenesis and angiogenesis

open access: yesMaterials Today Bio, 2022
In situ regeneration of large-segment bone defects is a difficult clinical problem. Here, we innovatively developed magnetically oriented micro-cellulose fibres using nano-hydroxyapatite/chitosan (CEF/Fe3O4/HA/CS) and loaded an NFκB pathway inhibitor on ...

PQQ ameliorates skeletal muscle atrophy, mitophagy and fiber type transition induced by denervation via inhibition of the inflammatory signaling pathways.

open access: yesAnnals of Translational Medicine, 2019
Background Skeletal muscle atrophy involves and requires widespread changes in skeletal muscle gene expression and signaling pathway, resulting in excessive loss of muscle mass and strength, which is associated with poor prognosis and the decline of life

Mussel‐Bioinspired Edible Ca2+‐Crosslinked Alginate Hydrogel Electrodes for Glucose Gastrointestinal Monitoring

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
A fully edible soft electrode is engineered from Ca2⁺‐crosslinked alginate integrated with polydopamine, silver nanoparticles, and food‐grade glucose oxidase. The hybrid hydrogel combines ionic and electronic conduction, enabling efficient glucose‐to‐H2O2 conversion and catalytic reduction in simulated intestinal fluid.

Towards a complete next-to-logarithmic description of forward exclusive diffractive dijet electroproduction at HERA: real corrections

open access: yes, 2019
We studied the $ep\rightarrow ep+2jets$ diffractive cross section with ZEUS phase space. Neglecting the $t$-channel momentum in the Born and gluon dipole impact factors, we calculated the corresponding contributions to the cross section differential in $\

Polarised deep inelastic scattering accompanied by a forward jet as a probe of the $\ln^2(1/x)$ resummation [PDF]

open access: yes, 1999
We argue that the production of forward jets in polarised deep inelastic scattering can be a useful tool for probing the double $ln^2(1/x)$ resummation effects which control the polarised deep inelastic scattering for small values of the Bjorken ...

Exploring Ectoine Production From Methanol, Formate, and Electrochemically Produced Formate by Methyloligella halotolerans

open access: yesEngineering in Life Sciences, Volume 26, Issue 1, January 2026.
ABSTRACT Microbial synthesis using renewable C1‐carbon sources like electrochemically produced formate (e‐formate) represents a promising approach for climate‐neutral chemical production. This study investigates formate utilization for ectoine biosynthesis by the halophilic methylotroph Methyloligella halotolerans.
