Bacteria in the airways of patients with cystic fibrosis are genetically capable of producing VOCs in breath. [PDF]

open access: yes, 2016
Breath contains hundreds of volatile organic compounds (VOCs), the composition of which is altered in a wide variety of diseases. Bacteria are implicated in the formation of VOCs, but the biochemical mechanisms that lead to the formation of breath VOCs ...

Global atmospheric budget of acetaldehyde: 3-D model analysis and constraints from in-situ and satellite observations [PDF]

open access: yes, 2010
We construct a global atmospheric budget for acetaldehyde using a 3-D model of atmospheric chemistry (GEOS-Chem), and use an ensemble of observations to evaluate present understanding of its sources and sinks.

The importance of acetaldehydein the metabolism and mechanismof ethyl alcohol action

open access: yesAlcoholism and Drug Addiction, 2019
Acetaldehyde is the first metabolite of ethanol and may be formed by alcohol dehydrogenase (ADH), cytochrome P450 2E1 (CYP2E1) and catalase. ADH is an essential pathway that oxidises alcohol in peripheral tissues (primarily in the liver).

Aromatic Amines Exert Contrasting Effects on the Anticoagulant Effect of Acetaldehyde upon APTT

open access: yesAdvances in Hematology, 2014
The pharmacological effects of amphetamine, procaine, procainamide, DOPA, isoproterenol, and atenolol upon activated partial thromboplastin time in the absence and presence of acetaldehyde have been investigated.

Relationship between acetaldehyde concentration in mouth air and tongue coating volume

open access: yesJournal of Applied Oral Science, 2015
Objective Acetaldehyde is the first metabolite of ethanol and is produced in the epithelium by mucosal ALDH, while higher levels are derived from microbial oxidation of ethanol by oral microflora such as Candida species.

Stable isotope profiles reveal active production of VOCs from human-associated microbes. [PDF]

open access: yes, 2017
Volatile organic compounds (VOCs) measured from exhaled breath have great promise for the diagnosis of bacterial infections. However, determining human or microbial origin of VOCs detected in breath remains a great challenge.

Roles of free radical on the formation of acetaldehyde in model wine solutions under different ultrasound parameters: A key bridge-link compound for red wine coloration during ageing

open access: yesUltrasonics Sonochemistry, 2021
In order to explore the effects of ultrasound on the formation of acetaldehyde and its mechanism in model wine solutions, ultrasound conditions and free radicals were investigated by response surface methodology and electron paramagnetic resonance ...

Ent-Peniciherqueinone Suppresses Acetaldehyde-Induced Cytotoxicity and Oxidative Stress by Inducing ALDH and Suppressing MAPK Signaling

open access: yesPharmaceutics, 2020
Studies on ethanol-induced stress and acetaldehyde toxicity are actively being conducted, owing to an increase in alcohol consumption in modern society.

FANCD2 limits acetaldehyde‐induced genomic instability during DNA replication in esophageal keratinocytes

open access: yesMolecular Oncology, 2021
Individuals with Fanconi anemia (FA), a rare genetic bone marrow failure syndrome, have an increased risk of young‐onset head and neck squamous cell carcinomas (SCCs) and esophageal SCC.
