Exposure to Ambient Particulate Matter during Specific Gestational Periods Produces Adverse Obstetric Consequences in Mice

Conclusions: Adverse PM2.5-induced outcomes such as PTB and LBW are dependent upon the periods of maternal exposure. The results of these experimental studies could contribute significantly to air pollution policy decisions in the future. https://doi.org/10.1289/EHP1029 Received: 26 August 2016 Revised: 12 December 2016 Accepted: 23 January 2017 Published: 27 July 2017 Address correspondence to J.

Introduction In the United States, ∼11% of all pregnancies result in preterm birth (PTB; birth prior to 37 wk gestation) (March of Dimes 2014). Although the reasons for this outcome are varied, exposure of pregnant women to elevated levels of fine-sized ambient particulate matter (PM2.5) has been identified in numerous epid...

Authors: Llorens-Aguilar S, García-Soriano G, Roncero M, Barrada JR, Aardema F, O Connor K Abstract The purposes of this research were: (1) to analyse the psychometric properties of the Inferential Confusion Questionnaire-Expanded Version (ICQ-EV) in a Spanish population; (2) to explore the role of inferential confusion in obsessive-compulsive disorder (OCD); and (3) to compare the inferential confusion construct in non-clinical and clinical samples. A sample of 342 non-clinical participants and 66 patients with OCD completed the ICQ-EV Spanish adaptation as well as a set of questionnaires. Results confirmed...

This study investigated the adsorption of the multicomponent VOCs in a homemade CAR waste-based activated carbon (CAR-AC). A fixed-bed experimental setup was used to explore the adsorption and desorption of single- and multi-component VOCs. Surface adsorption and diffusion molecular models with different defects were built to study the underlying adsorption and diffusion mechanisms of multicomponent VOCs on CAR-AC. The adsorption amount of ethyl acetate in CAR-AC from multicomponent VOCs was 3.04 and 5.91 times higher than those of acetone and acetaldehyde, respectively, and the interaction energy between ethyl acetate and...

The development of highly-efficient magnetic COFs along with fast adsorption kinetic and high adsorption capacity is very promising. To achieve the purpose, thiol-functionalized magnetic covalent organic frameworks (M-COF-SH) with abundant accessible chelating sites were d...
