Co-existing ambient fine particulate matter exacerbated electronic cigarette toxicity on human respiratory cells.

Respiratory co-exposure to ambient PM and electronic cigarettes (e-cigarettes) frequently occurs in public. However, the combined effects on human respiratory health have not been well documented. To discuss potential co-effects and possible biological mechanisms, A549/THP-1 co-cultures and BEAS-2B cells were exposed to unvapedtobacco or mint-flavored e-liquids (0-7.

Associations between soft drinks intake and primary dysmenorrhea among Chinese undergraduate female students.

Primary dysmenorrhea (PD) is a common global health concern. However, limited studies explored the association between soft drinks intake and PD among female undergraduates in China. To determine the association between soft drinks (carbonated soft drinks, etc.

Associations between blood nickel and lung function in young Chinese: An observational study combining epidemiology and metabolomics.

Prior research has explored the relationship between occupational exposure to nickel and lung function. Nonetheless, there is limited research examining the correlation between blood nickel levels and lung function among young adults in the general population. The metabolomic changes associated with nickel exposure have not been well elucidated.

Co-culture of human alveolar epithelial (A549) and macrophage (THP-1) cells to study the potential toxicity of ambient PM: a comparison of growth under ALI and submerged conditions.

Fine particulate matter (PM) in the ambient atmosphere is strongly associated with detrimental health effects. However, these particles from various sources and regions are unlikely equally toxic. While animal studies are impractical for high-throughput toxicity testing, appropriate models are urgently needed.

Toxicity assessment of electronic cigarettes.

Sale of electronic cigarette (e-cigarette) products has exponentially increased in the past decade, which raise concerns about its safety. This updated review provides the available toxicology profile of e-cigarettes, summarizing evidence from and studies. Data regarding which components in e-liquids exhibit potential toxicities are inconsistent.

Ambient fine particulate matter induce toxicity in lung epithelial-endothelial co-culture models.

Epidemiological and toxicological studies have reported that ambient fine particulate matter (PM) exposure are linked to adverse effects of cardiopulmonary system. An in vitro suitable model that assesses the interaction among various cell types should be developed to explain the toxic mechanisms occurred in cardiopulmonary system. The Transwell culture method was used to establish bi-culture consisting of A549 alveolar epithelial cells monoculture in apical chamber and EA.

Effects of Fine Particulate Matter (PM2.5) on Systemic Oxidative Stress and Cardiac Function in ApoE(-/-) Mice.

Aim: In this study, we aimed to explore the toxic mechanisms of cardiovascular injuries induced by ambient fine particulate matter (PM2.5) in atherosclerotic-susceptible ApoE(-/-) mice. An acute toxicological animal experiment was designed with PM2.

Rat lung response to ozone and fine particulate matter (PM2.5) exposures.

Exposure to different ambient pollutants maybe more toxic to lung than exposure to a single pollutant. In this study, we discussed the inflammation and oxidative stress responses of rat lung caused by ozone and PM2.5 versus that of rats exposed to saline, ozone, or single PM2.

[Effects of ozone and fine particulate matter (PM2.5) on rat cardiac autonomic nervous system and systemic inflammation].

Objective: To study the effects of ozone and fine particulate matter (PM2.5) on rat cardiac autonomic nervous system and systemic inflammation and the interconnected relationship of these two pathways.

Methods: 48 Wistar rats were randomly assigned to 8 groups (n = 6).

Effects of ozone and fine particulate matter (PM(2.5)) on rat system inflammation and cardiac function.

In order to understand the toxic mechanisms of cardiovascular system injuries induced by ambient PM(2.5) and/or ozone, a subacute toxicological animal experiment was designed with exposure twice a week for 3 continuous weeks. Wistar rats were randomly categorized into 8 groups (n=6): 1 control group, 3 groups exposed to fine particulate matters (PM(2.

[Application of the nasal lining flap to correct the wide unilateral complete cleft lip].

Objective: To study use of nasal lining flap in correction of the wide complete unilateral cleft lip.

Methods: 78 patients with wide complete cleft lip were. operated, firstly to be sure.

Anatomy of the nasal cartilages of the unilateral complete cleft lip nose.

The purpose of this study was to disclose the relationship between the anomaly of the cartilaginous framework and the nasal deformity of cleft lip. The noses of six stillborn infants with unilateral complete cleft lip were carefully dissected. The size and weight of the lower lateral cartilages were measured to determine whether there was a significant difference between the normal and involved sides.
