The cavity ringdown absorption spectrum of acrolein (propenal, CH(2)=CH-CH=O) was recorded near 412 nm, under bulk-gas conditions at room temperature and in a free-jet expansion. The measured spectral region includes the 0(0)(0) band of the T(1)(n, π*) ← S(0) system. We analyzed the 0(0)(0)
Acrolein is a highly reactive unsaturated aldehyde widely present in the environment, particularly as a product of tobacco smoke. Our previous studies indicated the adverse consequences of even short-term acrolein exposure and proposed a molecular mechanism of its potential harmful effect on oral
We investigated whether inhaling peak concentrations of aldehydes several times daily is more damaging than semi-continuously inhaling low-dose aldehydes. We exposed Xpa-/-p53+/- knock-out mice either intermittently or semi-continuously to mixed acetaldehyde, formaldehyde, and acrolein. The
The goal of this study was to characterize the respiratory tract toxicity of acrolein, including nasal and pulmonary effects, in adult male F344 rats. Animals underwent whole-body exposure to 0, 0.02, 0.06, 0.2, 0.6, or 1.8 ppm acrolein for 6 hr/day, five days/week for up to 65 exposure days (13
We investigate here the vertical n → π(*) and π → π(*) transitions of s-trans-acrolein in aqueous solution by means of a polarizable continuum model (PCM) we have developed for the treatment of the solute at the quantum Monte Carlo (QMC) level of the theory. We employ the QMC approach which allows
In this work, a new magnetic nanocomposite was prepared for the specific isolation of CD45 positive cells. Acrolein (AC) and acrylated β-cyclodextrin (ACD) were used as monomers in order to polymerize on the surface of Fe₃O₄ magnetic nanoparticles (MNPs) via surface initiated radical polymerization.
The ultrastructure of lipid bodies within developing, dormant, and germinating Tilletia caries (DC). Tul. (race T-16) teliospores was studied by freeze-etching and thin-sectioning techniques. When teliospores were prefixed in sodium cacodylate-buffered glutaraldehyde-acrolein for 24 h before further
Acrolein is a highly electrophilic α,β-unsaturated aldehyde and is associated with human diseases. It is formed by Maillard reaction during food processing and could be detected in the emissions of overheated cooking oils. Consequently, humans are at risk of acrolein exposure through OBJECTIVE
An oral cavity is a place especially susceptible to oxidative damage. It is subjected to many environmental pro-oxidative factors or factors that have the ability to generate reactive oxygen species (ROS). The aim of this article is to present the main sources of ROS and oxidative stress
Introduction: The diversity of e-liquids along with higher powered e-cigarette nicotine delivery devices are increasing. This study evaluated the effect of voltage and e-liquid composition on particle size, nicotine deposition in a human
Inhaled irritants can cause respiratory depression by simulating trigeminal nerves in the nasal cavity. This decrease in inhalation rate results in a decrease in the rate of the irritant gases flowing to the stimulated nerves, creating a complex feedback response. Previously, a model was created to
Tea is produced from the Camellia sinensis plant and can generally be divided into categories based on how they are processed. In general, green tea that is unfermented C. sinensis has been considered superior to black tea in health benefits. It contains a unique set of catechins that possess
Bidi smoke, a complex mixture of toxic and carcinogens chemicals causes a large and growing number of premature deaths in South Asian countries especially in India and Bangladesh. The evolved products during the thermal degradation of bidi tobacco powder (BTP) have been measured by using TG-FTIR-MS
2,4-Hexadienal, a colorless to yellow liquid with a pungent "green" or citrus odor, is used as a food additive for flavor enhancement, as a fragrance agent, as a starting material or intermediate in synthetic reactions in the chemical and pharmaceutical industries, as a fumigant, and as a corrosion
Electronic cigarettes (ECs) are categorized into generations which differ in terms of design, aerosol production, and customizability. Current and former smokers prefer third-generation devices that satisfy tobacco cravings more effectively than older generations. Recent studies indicate that EC
