Electronic address:

Exposure to air pollution and other environmental inhalation hazards, such as occupational exposures to dusts and fumes, aeroallergens, and tobacco smoke, is a significant cause of chronic lung inflammation leading to respiratory disease. It is now recognized that resolution of inflammation is an active process controlled by a novel family of small lipid mediators termed "specialized pro-resolving mediators" or SPMs, derived mainly from dietary omega-3 polyunsaturated fatty acids. Chronic inflammation results from an imbalance between pro-inflammatory and pro-resolution pathways. Read More

Cells 2019 Feb 3;8(2). Epub 2019 Feb 3.

Department of Biomedical Sciences, University of North Dakota, Grand Forks, ND 58203, USA.

Autophagy is a highly conserved catabolic process involving autolysosomal degradation of cellular components, including protein aggregates, damaged organelles (such as mitochondria, endoplasmic reticulum, and others), as well as various pathogens. Thus, the autophagy pathway represents a major adaptive response for the maintenance of cellular and tissue homeostasis in response to numerous cellular stressors. A growing body of evidence suggests that autophagy is closely associated with diverse human diseases. Read More

Department of Chemistry and Chemical Biology, McMaster University, Hamilton, Ontario, L8S 4M1, Canada.

Urinary 1-hydroxypyrene (OH-Pyr) is widely used for biomonitoring human exposures to polycyclic aromatic hydrocarbons (PAHs) from air pollution and tobacco smoke. However, there have been few rigorous validation studies reported to ensure reliable OH-Pyr determination for occupational health and risk assessment. Herein, we report an inter-laboratory method comparison for urinary OH-Pyr when using gas chromatography-high-resolution mass spectrometry (GC-HRMS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) on urine specimens collected from firefighters (n = 42) deployed at the 2016 Fort McMurray wildfire.

Eucalyptol promotes lung repair in mice following cigarette smoke-induced emphysema.

Phytomedicine 2019 Mar 8;55:70-79. Epub 2018 Aug 8.

Instituto de Ciências Biomédicas, Universidade Federal do Rio de Janeiro, Brazil. Electronic address:

Background: Eucalyptol is a monoterpenoid oil present in many plants, principally the Eucalyptus species, and has been reported to have anti-inflammatory and antioxidative effects.

Hypothesis/purpose: Since the potential effect of eucalyptol on mouse lung repair has not yet been studied, and considering that chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide, the aim of this study was to investigate eucalyptol treatment in emphysematous mice.

Study Design: Male mice (C57BL/6) were divided into the following groups: control (sham-exposed), cigarette smoke (CS) (mice exposed to 12 cigarettes a day for 60 days), CS + 1 mg/ml (CS mice treated with 1 mg/ml eucalyptol for 60 days), and CS + 10 mg/ml (CS mice treated with 10 mg/ml eucalyptol for 60 days).

Fate of the inhaled smoke particles from fire scenes in the nasal airway of a realistic firefighter: A simulation study.

J Occup Environ Hyg 2019 Jan 22:1-13. Epub 2019 Jan 22.

b School of Engineering - Mechanical and Automotive , RMIT University , Bundoora , Victoria , Australia.

Understanding the inhalation, transport and deposition of smoke particles during fire missions are important to evaluating the health risks for firefighters. In this study, measurements from Underwriters Laboratories' large-scale fire experiments on smoke particle size distribution and concentration in three residential fire scenes were incorporated into models to investigate the fate of inhaled toxic ultrafine particulates in a realistic firefighter nasal cavity model. Deposition equations were developed, and the actual particle dosimetry (in mass, number and surface area) was evaluated. Read More

A preliminary investigation of lung availability of cannabinoids by smoking marijuana or dabbing BHO and decarboxylation rate of THC- and CBD-acids.

Forensic Sci Int 2019 Feb 6;295:207-212. Epub 2019 Jan 6.

Landeskriminalamt Nordrhein-Westfalen, KTI - Teildezernat 51.2 Betäubungsmittel, Völklinger Strasse 49, 40221, Düsseldorf, Germany.

Highly potent cannabis concentrates obtained by butane or by supercritical carbon dioxide-extraction are gaining popularity. These extracts called butane hash oil (BHO) with Δ-tetrahydrocannabinolic acid A (THCA) contents above 60% are consumed by flash vaporization on a glowing titanium nail, followed by inhalation of the resulting vapor through a water pipe in a single puff - a technique referred to as "dabbing". We herein investigated the decarboxylation rate of THCA during artificial smoking of cannabis plant material and simulated dabbing, and the lung availability of Δ-tetrahydrocannabinol (THC) which we define as the recovery of THC in the smoke and vapor condensates.

Short-term regulation of the hepatic activities of cytochrome P450 and glutathione S-transferase by nose-only cigarette smoke exposure in mice.

Food Chem Toxicol 2019 Mar 3;125:182-189. Epub 2019 Jan 3.

College of Pharmacy, Chungnam National University, Republic of Korea. Electronic address:

The present study aimed to determine the effects of cigarette smoke on the regulation of hepatic cytochrome P450 (CYP) and glutathione S-transferase (GST) enzymes in male BALB/c mice exposed to nose-only cigarette smoke for 4 days. There were no significant increases in serum liver injury markers (alanine aminotransferase and aspartate aminotransferase) or oxidative stress (total antioxidant capacity, malondialdehyde, and glutathione disulfide/reduced glutathione) following cigarette smoke exposure, but malondialdehyde was elevated in the bronchoalveolar lavage fluid of smoke-exposed mice. Additionally, the hepatic microsomal protein levels of Cyp1a and Cyp2b, and the activities of ethoxyresorufin O-deethylase, pentoxyresorufin O-depenylase, and chlorzoxazone 6-hydrxylase, were elevated in smoke-exposed mice.

Cinnamaldehyde in flavored e-cigarette liquids temporarily suppresses bronchial epithelial cell ciliary motility by dysregulation of mitochondrial function.

Am J Physiol Lung Cell Mol Physiol 2019 Mar 3;316(3):L470-L486. Epub 2019 Jan 3.

Curriculum in Toxicology, School of Medicine, University of North Carolina , Chapel Hill, North Carolina.

Aldehydes in cigarette smoke (CS) impair mitochondrial function and reduce ciliary beat frequency (CBF), leading to diminished mucociliary clearance (MCC). However, the effects of aldehyde e-cigarette flavorings on CBF are unknown. The purpose of this study was to investigate whether cinnamaldehyde, a flavoring agent commonly used in e-cigarettes, disrupts mitochondrial function and impairs CBF on well-differentiated human bronchial epithelial (hBE) cells.
