The variable success in the outcome of randomised controlled trials supplementing coenzyme Q10 (CoQ10) may in turn be associated with a number of currently unresolved issues relating to CoQ10 metabolism. In this article, we have reviewed what is currently known about these factors and where gaps in knowledge exist that need to be further elucidated. Issues addressed include (i) whether the bioavailability of CoQ10 could be improved; (ii) whether CoQ10 could be administered intravenously; (iii) whether CoQ10 could be administered via alternative routes; (iv) whether CoQ10 can cross the blood-brain barrier; (v) how CoQ10 is transported into and within target cells; (vi) why some clinical trials supplementing CoQ10 may have been unsuccessful; and (vii) which is the most appropriate tissue for the clinical assessment of CoQ10 status.

Parkinson's disease (PD) stands as the sec most prevalent incapacitating neurodegenerative disorder characterized by deterioration of dopamine-producing neurons in the substantia nigra. Coenzyme Q10 (CoQ10) has garnered attention as a potential antioxidant, anti-inflammatory agent and enhancer of mitochondrial complex-I activity. This study aimed to examine and compare the effectiveness of liposomal and non-encapsulated CoQ10 in rotenone induced-PD mouse model over a 21-day treatment duration.

Introduction: Ferroptosis is an iron-dependent form of cell death triggered by the excessive accumulation of lipid peroxides. Understanding the regulatory mechanisms of ferroptosis and developing strategies to target this process hold significant clinical applications in tumor therapy.
Objective: Our study aims to search for novel candidate genes involved in the regulation of ferroptosis and to investigate their mechanism of action in ferroptosis and tumor therapy.

Coenzyme Q (CoQ) and closely related compounds with varying isoprenoid tail lengths (CoQ, = 6-9) are biochemical cofactors involved in many physiological processes, playing important roles in cellular respiration and energy production. Liquid chromatography (LC) coupled with single or tandem mass spectrometry (MS) using electrospray (ESI) or atmospheric pressure chemical ionization (APCI) is considered the gold standard for the identification and quantification of CoQ in food and biological samples. However, the characteristic fragmentation exhibited by the CoQ radical anion ([M], / 862.

However, limited research exists on their effects in non-diabetic patients, particularly concerning mitochondrial function. This case report investigates the potential of altered mitochondrial dysfunction as a cause of side effects of GLP-1 medications in patients without type 2 diabetes.

Background: Seminal oxidative stress has been shown to be a key factor in the development of male infertility. However, the benefits of infertility treatments with antioxidants such as coenzyme Q10 (CoQ10) remains controversial.
Objectives: The aim of the present study was to assess the effects of CoQ10 supplementation on semen quality, i.
