Animal studies were conducted in compliance with the US Department of Health and Human Services Guide for the Care and Use of Laboratory Animals and were approved by the Institutional Animal Care and Use Committee of Duke University. In our standard protocol, C57Bl6/J mice (4–12 wk old; The Jackson Laboratory) were deeply anesthetized with ketamine/xylazine (100/10 mg/kg) and immediately transcardially perfused for 10 min with 15 ml fixative containing 2% paraformaldehyde, 2% glutaraldehyde, and 0.05% CaCl2 in 50 mM MOPS buffer, pH 7.4. Their enucleated eyes were postfixed in the same fixative for 1 h. A modification of this protocol included mouse perfusion with 10 ml heparin (1,000 U/ml) saline before paraformaldehyde/glutaraldehyde administration. Alternatively, we used the protocol used in the study by Chuang et al. (2007) (link). In brief, mice were sequentially perfused with 10 ml heparin saline administered for 2 min, 20 ml 4% paraformaldehyde/3.75% acrolein (Polysciences) in 0.1 M sodium phosphate buffer, pH 7.4, and finally 60 ml of 4% paraformaldehyde in 0.1 M sodium phosphate buffer. Enucleated eyes were postfixed in 2% glutaraldehyde in 0.1 M sodium phosphate buffer, pH 7.4, for 1 h. A modification of this protocol included direct mouse perfusion with fixative, omitting the saline step. Upon the completion of animal perfusion, eyeballs were rinsed with PBS, cornea and lens were removed, the posterior eye cups were embedded in 5% agar (A1296; Sigma-Aldrich), and cut on a vibratome (Leica) at 100–200-µm sections.
A subset of experiments was performed with immersion-fixed eyecups. Mice were euthanized with CO2 and decapitated. Eyes were enucleated and eyecups immersed in 2% paraformaldehyde, 2% glutaraldehyde, and 0.05% CaCl2 in 50 mM MOPS buffer, pH 7.4, or 2% glutaraldehyde and 0.05% CaCl2 in 50 mM MOPS buffer for 1 h. Posterior eye cups were then embedded and sectioned as described in the preceding paragraph.

Social interaction behavior was investigated using an apparatus consisting of a large open field (Fig. 1a, 89×63×60 cm) containing a small wire cage (14×17×14.5 cm). Each focal mouse was introduced into the open field for 3 min to habituate, and we recorded the amount of time the focal mouse spent interacting with the empty wire cage (within 8 cm, see blue box in Fig. 1A) using a video tracking system (Stoelting, Wood Dale, IL). Next an unfamiliar, same sex virgin mouse was introduced into the wire cage. For 3 min we recorded the amount of time the focal mouse spent interacting with the wire cage. We also measured time spent in the two corners opposite the wire cage (8×8 cm, Fig 1A) and total distance traveled as an estimate of total activity. After each test the arena was cleaned with 70% ethanol and dried before the next mouse was tested. Social interaction was assessed at 24 hours and 4 weeks after social defeat exposure. Different stimulus mice were used for the two tests. In between the two social interaction tests the mice were undisturbed except for routine cage changes. Immediately after testing at 4 weeks, each focal mouse was anesthetized with isoflurane and euthanized by decapitation (14:45–17:00 PST). Brains were collected immediately after testing to detect changes in phosphorylated CREB and ERK, which we have previously quantified in California mice after 7 min resident-intruder tests [30] (link), [38] (link). Trunk blood was collected in heparinized tubes and centrifuged to collect plasma (see below for corticosterone assay methods). Brains were quickly removed and immersion fixed in 5% acrolein in phosphate buffered saline (PBS). Each female was lavaged post-mortem. Estrous cycle stage was determined by assessing the presence of leukocytes, nucleated epithelial cells, and/or cornified cells [30] (link), [39] (link).

Serum (equal volumes) or protein lysates (10 µg) were heated with sample buffer (3.2% SDS, 32% glycerol, 0.16% bromophenol blue, 100 mM Tris-HCl, pH 6.8, 8% 2-mercaptoethanol). They were then electrophoresed on Criterion Stain-free 4–20% SDS-PAGE gels (Bio-Rad) and transferred onto nitrocellulose membranes at 100 volts for 30 min. The membranes were blocked with TBS containing 5% nonfat dry milk and probed with anti-C3 antibody (Santa Cruz, sc-28294, 1:1,000) or anti-acrolein antibody (NOVUS, NB200–556, 1:1,000) overnight at 4 °C. They were then washed three times in TBS containing 0.1% Tween 20 and incubated with horseradish peroxidase-conjugated secondary antibody for 2 h at room temperature. Signals were detected using enhanced chemiluminescence and Gel Doc System (Bio-Rad). The blots were stripped and probed for housekeeper proteins transferrin (serum) or β-actin (tissue lysate). The signal intensity was quantified using Image Lab (Bio-Rad) and NIH ImageJ software (v1.45 s).

This study examined 50 biomarkers associated with exposure to tobacco. Biomarkers were selected from several classes of known tobacco product constituents, including (1) nicotine metabolites, (2) TSNAs, (3) metals, (4) PAHs, and (5) VOCs. A complete listing of geometric means for all 50 biomarkers among each user group can be found in eTable 2 in the Supplement.
A representative biomarker from each panel was selected for visualization of study results based on its documented association with tobacco exposure and linkage to tobacco-related disease development or adverse health effects. These biomarkers included metabolites of nicotine, tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), lead, cadmium, naphthalene, pyrene, acrylonitrile, acrolein, and acrylamide.13 (link),31 (link),32 (link),33 (link),34 (link),35 (link),36 ,37 (link),38 (link),39 ,40 (link),41 ,42 (link) To estimate nicotine exposure, total nicotine equivalents were calculated by taking the molar sum of cotinine and trans-3′-hydroxycotinine values. Table 1 outlines the potential clinical relevance of selected biomarkers.

Governed by the conservation laws of nature, the Computational Fluid-Particle Dynamics (CFPD) and Physiologically Based
Toxicokinetic (PBTK) model is a promising tool to assess the chronic exposure risks of EC aerosols and provide informative and
high-resolution data promptly. The schematic of the CFPD-PBTK modeling framework is shown in Figure
1
. Integrating the multiscale model validations and optimizations, the CFPD-PBTK model provides local information about how
different levels of puffing may affect the deposition and translocation of toxicants in both lung and systemic regions. The CFPD model
is developed based on Euler-Lagrange scheme (Feng, Kleinstreuer, Castro, & Rostami, 2016 )
specifically for multi-component EC aerosol dynamics in an idealized human upper airway model from mouth to Generation 3 (G3). The
existence of the dominant chemicals of the nicotine, acrolein, formaldehyde, vegetable glycerin (VG), and propylene glycol (PG) are
tracked both in the particle and vapor forms. Also, the wall of the respiratory system is considered as a sink with fractional to
complete absorption for the uptake of the chemicals into the systemic region. The PBTK model for inhaled toxicants is developed and
validated. It is assumed that the toxicant`s distribution through blood flow with the biological structure of tissues which are
homogeneous rate-limited diffusion (Robinson, Balter, & Schwartz, 1992 (link)). The important
mechanisms including absorption, distribution, metabolism, and excretion in each organ for each toxicant are considered. Physiologic
parameters (cardiac output, ventilation rate, blood flow rate to the organs and organ volumes) are obtained and optimized accordingly.
The system of governing equations and boundary conditions are provided in the Supplemental Information (SI).

Cells (1 × 105) were plated on 22 × 22 mm glass coverslips coated with 5 µg/mL of fibronectin (354008; Corning, Steuben, NY, USA) in DMEM. To determine the effects of iron chelation on lipid peroxidation products 4-hydroxynonenal (HNE) and acrolein levels in retinal ECs, 5.0 × 104 cells were incubated with 50 µM or 10 µM DFO (Sigma) for 24 h. To demonstrate the effects of iron chelation in VE-cadherin localization in retinal EC layer, 5.0 × 105 cells were incubated with iron chelator DFO (10 or 20 µM) for 48 h. The cells were fixed with 4% paraformaldehyde (15710; Electron Microscopy Sciences, Hatfield, PA, USA) in PBS for 15 min on ice. The cells were then rinsed with PBS three times and permeabilized with 0.1% Triton X-100 for 10 min at room temperature. After being washed with PBS three times, the cells were blocked with 1% bovine serum albumin (BSA, BP-9703; Thermo Fisher) in TBS for 1 h. The cells were then incubated with primary antibodies overnight at 4 °C. The primary antibodies used are as follows: anti-estrogen receptor α (06-935; Millipore), anti-Phosphorylated-SMAD1 (Cell Signaling), anti-SMAD1 (Cell Signaling), anti-VE-cadherin (BD Biosciences), anti-4-hydroxynonenal (HNE11-S; Alpha diagnostics, Burlington, NC), and anti-Acrolein (MA5-27553; Invitrogen). The cells were washed with TBS three times for 5 min and incubated with appropriate fluorescent-dye-conjugated secondary antibodies (1:1000, Jackson ImmunoResearch) for 1 h at room temperature. The cells were rinsed with TBS three times and incubated with DAPI (1:2000, D1306; Invitrogen) for 5 min. The cells were mounted on glass slides using Fluoromount-G mounting solution (0100-01; SouthernBiotech, Birmingham, AL, USA) and photographed using a Zeiss Fluorescence microscope (Axiophot, Zeiss, Germany) equipped with a digital camera.

The cigarillos and LWCs tested
in this study represented a range of brand names that are available
in the U.S. market. This study was performed in two different time
periods. For the first study, one cigarillo and two LWCs were purchased
in Chesapeake, VA, shipped to an ISO 17025-accredited analytical laboratory
(Labstat Inc., Kitchener, Ontario) on September 19, 2016, and analyzed
in November 2016. For the second study, 10 cigarillos and five LWC
brands were purchased in Chesapeake, VA, shipped to the analytical
laboratory on September 22, 2017, and analyzed in November 2017. The
second study also analyzed two reference cigarettes (i.e., 3R4F, 1R6F)
that were purchased from the University of Kentucky (Lexington, KY).
The two reference cigarettes contain similar physical properties and
smoke chemistry.17 (link) The tobacco products
were kept in their original packaging under ambient conditions and
stored at room temperature prior to testing. All the test products
were conditioned and smoked under the environmental conditions specified
in ISO 3402 (1999) “Tobacco and tobacco products—Atmosphere
for conditioning and testing”, which states that tobacco products
are conditioned at 22 ± 1 °C and relative humidity 60 ±
3% and smoked at 22 ± 2 °C and relative humidity 60 ±
5%.
Mainstream tobacco smoke was collected using a linear smoking
machine fitted with an impinger containing 80 mL of 2,4-DNPH solution.
All reagents were analytical reagent grade, unless otherwise stated.
The derivatized solution was syringe-filtered and diluted with 1%
Trizma base aqueous acetonitrile solution. Additional solutions necessary
for the validation of the derivatization efficiency (e.g., calibration
solutions using formaldehyde, acetaldehyde, acrolein, crotonaldehyde
chemical standards) and the analytical procedure were prepared from
commercially sourced acrolein with >99% purity.

The PTR-ToF-MS resolution
was ∼4800 with mass spectra recorded from 10 to 500 Da. In-flight
zero air measurements were subtracted. Ground calibrations were conducted
every 1–3 days using gravimetrically prepared multicomponent
VOC standards (Apel-Riemer Environmental Inc., Colorado, USA). The
following VOCs were included in the gas standards: methanol, acetonitrile,
acetaldehyde, ethanol, acrolein, dimethyl sulfide, isoprene, MACR
+ MVK, benzene, toluene, xylene, p-cresol, 1-,3-,5-trimethylbenzene,
D3 siloxane, D4 siloxane, D5 siloxane, propanol, butanol, acetone,
furan, furfural, benzaldehyde, monoterpenes (mixture of α- and
β-pinene and limonene), nonanal, acrylonitrile, methyl ethyl
ketone, and b-caryophyllene. For all m/z without a corresponding gas standard, sensitivities were derived
from a root function fit to reaction rate normalized sensitivities
of nonfragmenting and nonclustering gas-standard calibrated VOCs.
The estimated calibration uncertainty for gas-standard VOCs was 20%,
and 54% for all other VOCs. Isoprene and acetaldehyde were corrected
for interferences from fragmentation of larger molecules,22 (link) and benzene was calibrated on m/z 78.05 to avoid interference of benzaldehyde fragments.22 (link) Monoterpenes detected at m/z 137.13 may include fragments of monoterpenoids with a
parent mass of m/z 155.14 (C10H18O).23 (link),24 (link)Level flight
legs of at least 10 km length were chosen for wavelet analysis. Lag
times between vertical wind and VOC were determined separately for
each VOC and flight segment by searching for the maximum covariance
within a 4 s window. Wind and VOC data (10 Hz) were aligned using
these lag times. Continuous wavelet transformation, which deconvolutes
the covariance within a timeseries throughout both the frequency and
time (distance) domains, was applied building up on the work of Karl
et al.,14 (link) Misztal et al.,13 (link) and Wolfe et al.,25 (link) and yielded
VOC fluxes. For each data point along the flight path, the wavelet
transformation of the data produced the local wavelet cospectra. The
flux timeseries was created through integration over all frequencies.
To remove turbulence-related artificial emission and deposition, a
two-sided moving average of 2 km was applied to the 10 Hz fluxes and
subsampled to 200 m.
Surface fluxes were calculated from the
airborne fluxes by correcting
for chemical vertical divergence (i.e., oxidative loss) and physical
vertical divergence (loss through horizontal advection and entrainment).
The physical vertical divergence was substantial (on average a factor
of 2) since there were strong marine winds and a low boundary layer.
This led to a relatively large uncertainty contribution to this correction
(∼70%). Total uncertainties depend on the VOC, ranging from
75 to 86% for gas-standard calibrated VOCs, and 90–170% for
the more than 400 VOCs that were calibrated using the theoretical
approach. Average mixing ratios, fluxes, corrections, and uncertainties
for each species are listed in Data S1 of Pfannerstill et al.20
