Short-term e-cigarette vapour exposure causes vascular oxidative stress
Aims
Traditional combustible cigarettes and as an effective means
of smoking were (e) -cigrettes marketed as ‘healthy’. However, there is a lack
of data to support these claims. In fact, e-cigarettes are associated with
endothelial malfunction and with oxidative stress in the vasculature and lungs.
The mechanisms underlying these side effects are not clear. Here we
investigated the effects of e-cigarette vapor on vascular function in smokers
and experimental animals to determine the underlying mechanisms.

Methods and results
As a result of acute smoking on cigarettes, endothelial
function in chronic smokers was determined by flow de-intervention. In mice,
e-cigarette vapor without nicotine had an adverse effect on endothelial
function, oxidative stress markers, inflammation, and lipid peroxide than vapor
containing nicotine. These effects of e-cigarette vapor were mostly absent in
mice that did not have NADPH phagocytic oxidation (NOX-2) nor were they treated
with macitentan of the endothelin relationship or the FOXO3 agent beetles. We
also decided that the product made acrolein e-cigarettes, retroactive
aldehydes, many of the effects of wind-cigarettes NOX-2-dependent cigarettes e-cigarettes
involving breeding in vitro blood vessels.
Conclusions
The exposure of e-stress cigarette, cerebral, and pulmonary
oxidation steam increases through NOX-2-dependent mechanism. Our study
identifies the toxic acidity aldehyde as the main intermediary of the observed
vascular adverse effects. Therefore, e-cigarette cigarettes can encourage the
harmful effects of cardiovascular, pulmonary and cerebrovascular. As the use of
e-cigarettes is increasing, particularly among young people, our data indicates
that aggressive steps are needed to limit their health risks.

Translational perspective
With the current studies, we show that cigarette smoking has
created an endothelial impairment function in chronic smokers determined by
flow de-intervention. Transfusion experiments in mice showed that e-cigarette
vapor causes oxidative stress in the brain, lung and vessels, stimulates
inflammation, and lipid peroxide These mice did not have the adverse health
effects of mainly NADPH (NOX-2) phagocytic oxide (NOX-2). largest. The
ero-cigarette ero-cigarette, retroactive aldehydes, many of the effects of
wind-cigarettes NOX-2-dependent cigarettes e-cigarettes used in vitro blood
incubation. These results show that the effects of marked cardiovascular,
pulmonary and cerebro-vascular effects may result in the use of e-cigarettes.
As the use of e-cigarettes is increasing, particularly among young people, our
data suggests that there is a need for aggressive measures to limit the cardiovascular
and cerebro-vascular health risks associated with e-cigarettes.
Introduction
According to the results of the Global Study of Disease
(GBD), smoking was ranked second of all risk factors for global deaths,
immediately following high blood pressure.1 Electronic marketing (e)
-cigearettes as a healthy alternative 'traditional cigarettes, and are
described as an effective method of stopping smoking.2 As a result, cigarette
usage has grown rapidly, particularly in young people, so e-cigarettes by 2014
were the most common tobacco. product used in USA.3 The US Center for Disease
Control and Prevention (CDC) reports that the use of e-cigarettes increased
significantly from 1.5% to 20.8% (053.05 million students) between 2011 and
2018. This increases to Rapid concern raised about poor health effects on
secondary school pupils and high cigarettes in e-cigarettes.4 This anxiety is
compounded by the release of a high nicotine steam apparatus without a full
understanding of these. health consequences.5 there are also significant
concerns from recent reports from the CDC, the Food and Drug Agency (FDA), and
State Health Departments on ongoing investigations into serious pulmonary
diseases and deaths among e-cigarette users6 and preliminary reports. a coordinated
public health investigation.
There is a lack of clarity about the overall consequences of
using the cigarette through a population. The majority of available studies
provide evidence that e-cigarette vapor is slightly worse than smoking tobacco
cigarettes. however, the number of studies and the size of mechanistic insights
are limited. If e-cigarette vapor is considered to be a reduction in the
average age of first-time users (e) -cigearette, the 'healthier' e-cigarette
profile may be recalled (or even reversed) at the highest level. of adolescent
users. Therefore, e-cigarette vapor may have a negative impact on the lifetime
of the population adjusted by a disability and thus gives it a higher disease
burden.
There is a need for a deeper understanding of the health
effects of e-cigarettes. Some reports describe that e-cigarette vapor can cause
vascular and cardiac malfunction, or oxidative stress and prompt inflammation
in the correlation. Similarly, vaping is linked to increased blood pressure and
enhanced thrombogenesis. Collectively, these consequences of evaporation would
be expected to begin the process of atherosclerosis and / or worse. Therefore,
in order to gain further insight into the cardiovascular consequences of
cigarette vapor, we studied mice using non-cigarette non-cigarette liquids with
nicotine and without it to determine the impact on vascular function
(endothelial). We also characterized the mechanisms for oxidative stress and
inflammation, and collected our fruit in human loyal cells and healthy smokers.
