Background: Breath-holding spells (BHS) are the most common form of non-epileptic paroxysmal events in infancy. The pathophysiology of BHS is not fully understood. Iron-deficiency anemia (IDA) may be a factor contributing to breath-holding spells. Although numerous reports have shown that elevated oxidative stress is implicated in the pathophysiology of neurodegenerative diseases and neurological conditions, such as epileptic seizures, brain damage, and neurotrauma, there are no data regarding the role of oxidative stress in the development of BHS. This study aimed to investigate oxidative stress in children with BHS.
Methods: This case-control study was conducted at the Department of Pediatric Neurology, Harran University School of Medicine, Sanliurfa, in Turkey. Blood samples from 31 patients (14 females, 17 males) with BHS which were taken at least 24 h after the BHS attack, and a control group of 35 healthy individuals (13 females, 22 males) were used for the measurement of the plasma total antioxidant capacity, total oxidant status, and oxidative stress index, hemoglobin concentration, serum iron, transferrin saturation and serum ferritin levels.
Results: The plasma total antioxidant capacity values were markedly lower and total oxidant status and oxidative stress index values in the BHS group were significantly higher than that in the controls (P ≤ 0.01).
Conclusion: Our data suggest that the value of oxidative stress was significantly higher in patients with BHS than in the controls. Conditions associated with increased oxidative stress such as IDA may be a risk factor for the development of BHS.

Background: Mitochondria-driven oxidative/redox stress and inflammation play a major role in chronic kidney disease (CKD) pathophysiology. Compounds targeting mitochondrial metabolism may improve mitochondrial function, inflammation, and redox stress; however, there is limited evidence of their efficacy in CKD.
Methods: We conducted a pilot randomized, double-blind, placebo-controlled crossover trial comparing the effects of 1200 mg/day of coenzyme Q10 (CoQ10) or 1000 mg/day of nicotinamide riboside (NR) supplementation to placebo in 25 people with moderate-to-severe CKD (estimated glomerular filtration rate [eGFR] <60mL/min/1.

Purpose: To investigate the effect of Rho-associated protein kinase (ROCK) inhibitor Y27632 on bioenergetic capacity and resilience of corneal endothelial cells (CECs) under metabolic stress.
Methods: Bovine CECs (BCECs) were treated with Y27632 and subjected to bioenergetic profiling using the Seahorse XFp Analyzer. The effects on adenosine triphosphate (ATP) production through oxidative phosphorylation and glycolysis were measured.

Chemical communication between marine bacteria and their algal hosts drives population dynamics and ultimately determines the fate of major biogeochemical cycles in the ocean. To gain deeper insights into this small molecule exchange, we screened niche-specific metabolites as potential modulators of the secondary metabolome of the roseobacter, . Metabolomic analysis led to the identification of a group of cryptic lipids that we have termed roseoceramides.

Laryngeal squamous cell carcinoma is a common type of head and neck cancer. This study investigated the role of the TRPM2 channel in doxorubicin (DOX)-induced cell damage in human laryngeal squamous cancer cells (Hep-2). Cells were exposed to various DOX concentrations and the appropriate dose was found.

NAFLD is one of the most common and rapidly increasing liver diseases. Procyanidin C1 and procyanidin C2, B-type trimeric procyanidins, show beneficial effects on regulating lipid metabolism. However, the mechanism underlying these effects remain elusive.
