Intravenous Administration of Coenzyme Q10 in Acute Period of Cerebral Ischemia Decreases Mortality by Reducing Brain Necrosis and Limiting Its Increase within 4 Days in Rat Stroke Model

Antioxidants, 2020
Oxidative stress plays a key role in the pathogenesis of ischemic stroke. Coenzyme Q10 has a multi-targeting effect and may protect the brain against ischemic damage.

Proteomic Insight Into Alzheimer's Disease Pathogenesis Pathways

PROTEOMICS, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a leading cause of dementia, but the pathogenesis mechanism is still elusive. Advances in proteomics have uncovered key molecular mechanisms underlying AD, revealing a complex network of dysregulated pathways, including amyloid metabolism, tau pathology, apolipoprotein E (APOE), protein degradation ...

Specific and rapid analysis of ubiquinones using Craven's reaction and HPLC with postcolumn derivatization

Journal of Lipid Research, 2007
A new method for the analysis of ubiquinones in various samples was developed using an HPLC system with postcolumn derivatization. Craven's reaction, a specific color reaction for the analysis of ubiquinones, was used in the system.

Coexistence of Wolbachia with Buchnera aphidicola and a secondary symbiont in the aphid Cinara cedri.

, 2004
Intracellular symbiosis is very common in the insect world. For the aphid Cinara cedri, we have identified by electron microscopy three symbiotic bacteria that can be characterized by their different sizes, morphologies, and electrodensities.

In vitro characterization of mitochondrial function and structure in rat and human cells with a deficiency of the NADH:ubiquinone oxidoreductase Ndufc2 subunit [PDF]

, 2017
Ndufc2, a subunit of the NADH:ubiquinone oxidoreductase, plays a key role in the assembly and activity of complex I within the mitochondrial OXPHOS chain. Its deficiency has been shown to be involved in diabetes, cancer and stroke.

Studies on Ubiquinone

Journal of Biological Chemistry, 1974
Abstract The total biosynthesis of ubiquinone-9 from p-hydroxy[U-14C]benzoate has been demonstrated in mitochondria isolated from rat liver slices preincubated with mevalonic acid. Two partial reactions were also demonstrated. These were the conversion of p-hydroxybenzoate to 5-demethoxyubiquinone-9 and sequentially, the conversion of 5 ...

The Conformational Changes Induced by Ubiquinone Binding in the Na+-pumping NADH:Ubiquinone Oxidoreductase (Na+-NQR) Are Kinetically Controlled by Conserved Glycines 140 and 141 of the NqrB Subunit*

Journal of Biological Chemistry, 2014
Background: Na+-pumping NADH:ubiquinone oxidoreductase (Na+-NQR) is a respiratory enzyme which reduces ubiquinone. Results: Two ubiquinone binding sites were found of which only one is catalytically relevant.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Identification of Ubiquinones in Honey: A New View on Their Potential Contribution to Honey’s Antioxidant State

Molecules, 2018
Honey is composed of macromolecules arranged into multicomponent colloidal particles dispersed in a supersaturated sugar solution. The core part of colloidal particles in honey is made up of high-molecular weight protein-polyphenol complexes. We designed

Elasticity sampling links thermodynamics to metabolic control

, 2013
Metabolic networks can be turned into kinetic models in a predefined steady state by sampling the reaction elasticities in this state. Elasticities for many reversible rate laws can be computed from the reaction Gibbs free energies, which are determined ...
