Oxidative stress (OS) has greatly interested the research community in understanding
damaging processes occurring in cells. OS is triggered by an imbalance between reactive …

Coenzyme Q10 (CoQ10) has a number of vital functions in all cells, both mitochondrial and
extramitochondrial. In addition to its key role in mitochondrial oxidative phosphorylation …

Quinones can in principle be viewed as a double-edged sword in the treatment of
neurodegenerative diseases, since they are often cytoprotective but can also be cytotoxic …

Abstract Coenzyme Q 10 (CoQ 10) is an essential component of the mitochondrial electron
transport chain. It is also an antioxidant in cellular membranes and lipoproteins. All cells …

Exposure to microgravity and ionizing radiation during spaceflight missions causes
excessive reactive oxygen species (ROS) production that contributes to cellular stress and …

Heavy metal exposure, in lead (Pb) particularly, is associated with severe neuronal
impairment though oxidative stress mediated by reactive oxygen species, and antioxidants …

The prevailing notion that reduced cofactors NADH and FADH 2 transfer electrons from the
tricarboxylic acid cycle to the mitochondrial electron transfer system creates ambiguities …

Objective Increased oxidative stress has been identified as a pathogenetic mechanism in
female infertility. However, the effect of specific antioxidants, such as coenzyme Q 10 (CoQ …

Physical frailty, an age-related decline in the physiological capacity and function of various
organs, is associated with higher vulnerability to unfavorable health outcomes. The …

Coenzyme Q10 (CoQ10) is a compound with a crucial role in mitochondrial bioenergetics
and membrane antioxidant protection. Despite the ubiquitous endogenous biosynthesis …
