Carbonyl Compounds Containing Formaldehyde Produced from the Heated Mouthpiece of Tobacco Sticks for Heated Tobacco Products

Molecules, 2020
Diverse harmful compounds can be emitted during the heating of tobacco sticks for heated tobacco products (HTPs). In this study, the generation of harmful compounds from the filter, instead of tobacco in tobacco sticks, was confirmed.

Using the Isolated Rat Placenta to Assess Fetoplacental Hemodynamics

Frontiers in Toxicology, 2022
Placental health is critical to fetal growth and maternal health during gestation. However, investigating placental flow in an ex-vivo isolated system where inflow is independently controlled has yet to be developed in the rat.

In vitro toxicoproteomic analysis of A549 human lung epithelial cells exposed to urban air particulate matter and its water-soluble and insoluble fractions

Particle and Fibre Toxicology, 2017
Background Toxicity of airborne particulate matter (PM) is difficult to assess because PM composition is complex and variable due to source contribution and atmospheric transformation.

Overview of Inhalation Toxicology [PDF]

Environmental Health Perspectives, 1990
The development of inhalation toxicology as a distinct discipline can be traced back well over one hundred years. The technology has advanced in terms of materials and designs used to construct inhalation chambers and the equipment used to generate controlled test atmospheres of a wide variety of gases, vapors, dusts, and droplets.

Comparative evaluation of the mutagenicity and genotoxicity of smoke condensate derived from Korean cigarettes [PDF]

Environmental Health and Toxicology, 2015
Objectives Cigarette smoking is associated with carcinogenesis owing to the mutagenic and genotoxic effects of cigarette smoke. The aim of this study was to evaluate the mutagenic and genotoxic effects of Korean cigarettes using in vitro assays.

Inhalation of Microplastics—A Toxicological Complexity [PDF]

Toxics
Humans are chronically exposed to airborne microplastics (MPs) by inhalation. Various types of polymer particles have been detected in lung samples, which could pose a threat to human health. Inhalation toxicological studies are crucial for assessing the effects of airborne MPs and for exposure-reduction measures.

Oxidant-induced epithelial alarmin pathway mediates lung inflammation and functional decline following ultrafine carbon and ozone inhalation co-exposure

Redox Biology, 2021
Environmental inhalation exposures are inherently mixed (gases and particles), yet regulations are still based on single toxicant exposures. While the impacts of individual components of environmental pollution have received substantial attention, the ...

Development of a Simple and Powerful Analytical Method for Formaldehyde Detection and Quantitation in Blood Samples

Journal of Analytical Methods in Chemistry, 2020
Human beings are easily exposed to formaldehyde (FA) in a living environment. Entry of FA into the human body can have adverse effects on human health, depending on the FA concentration.

Higher incidence of sperm granuloma in the epididymis of C57BL/6N mice

Laboratory Animal Research, 2018
C57BL/6N mice are inbred strains widely used in biomedical research. Hence, a large amount of basic data has been accumulated. However, in the field of histopathology, spontaneous data for relatively younger mice that are used more frequently are not yet
