Novel Cationic Prodrug of Ubiquinol-10 Enhances Intestinal Absorption via Efficient Formation of Nanosized Mixed-Micelles with Bile Acid Anions

open access: yesMolecules, 2020
The aim of this study was to develop a prodrug of ubiquinol-10 (UqH-10), the active form of ubiquinone-10 (Uq-10), for oral delivery. Bioavailability of UqH-10 is hampered by its high susceptibility to oxidation and water-insolubility.

Tissue-Specific Orchestration of Gilthead Sea Bream Resilience to Hypoxia and High Stocking Density [PDF]

open access: yes, 2019
Two different O-2 levels (normoxia: 75-85% O-2 saturation; moderate hypoxia: 42-43% O-2 saturation) and stocking densities (LD: 9.5, and HD: 19 kg/m(3)) were assessed on gilthead sea bream (Sparus aurata) in a 3-week feeding trial.

Mitochondria‐Nuclear Crosstalk: Orchestrating mtDNA Maintenance

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT The mitochondria (mt) and nucleus engage in a dynamic bidirectional communication to maintain cellular homeostasis, regulating energy production, stress response, and cell fate. Anterograde signaling directs mt function, while retrograde signaling conveys metabolic and stress‐related changes from mt to the nucleus. Central to this crosstalk is

Ubiquinone supplementation during lovastatin treatment: effect on LDL oxidation ex vivo1

open access: yesJournal of Lipid Research, 1998
A randomized, double-masked, placebo-controlled cross-over trial was carried out to evaluate whether ubiquinone supplementation (180 mg daily) corrects impaired defence against initiation of oxidation of low density lipoprotein (LDL) related to effective

Shuttle-mediated proton pumping across the inner mitochondrial membrane [PDF]

open access: yesarXiv, 2008
Shuttle-assisted charge transfer is pivotal for the efficient energy transduction from the food-stuff electrons to protons in the respiratory chain of animal cells and bacteria. The respiratory chain consists of four metalloprotein Complexes (I-IV) embedded in the inner membrane of a mitochondrion.

Biosynthesis and physiology of coenzyme Q in bacteria. [PDF]

open access: yes, 2014
International audienceUbiquinone, also called coenzyme Q, is a lipid subject to oxido-reduction cycles. It functions in the respiratory electron transport chain and plays a pivotal role in energy generating processes.

Dry Eye Disease: Oxidative Stress on Ocular Surface and Cutting‐Edge Antioxidants

open access: yesGlobal Challenges, EarlyView.
This review has systematically evaluated the oxidative damage of cornea, tear film, lacrimal gland, conjunctiva and meibomian gland for dry eye, and concluded the antioxidants that are either commercially available or in the research phase. GQDs: Graphene quantum dots; LF: lactoferrin; ROS: Reactive oxygen species; SOD: Superoxide dismutase; tFNA ...

Electron transfer pathway analysis in bacterial photosynthetic reaction center [PDF]

open access: yesarXiv, 2016
A new computational scheme to analyze electron transfer (ET) pathways in large biomolecules is presented with applications to ETs in bacterial photosynthetic reaction center. It consists of a linear combination of fragment molecular orbitals and an electron tunneling current analysis, which enables an efficient first-principles analysis of ET pathways ...
