Complementary multi‐omics profiling of chronic thromboembolic pulmonary hypertension reveals immune cell alterations, epigenetic changes, and genetically supported candidate genes

Animal Models and Experimental Medicine, EarlyView.
This study presents an integrative multi‐omics framework to uncover the molecular mechanisms and potential biomarkers of chronic thromboembolic pulmonary hypertension (CTEPH). Anthropometric and biochemical data were correlated using canonical correlation analysis, revealing key cardiometabolic associations. Single‐cell RNA sequencing identified immune

Polarized Infrared Emission by Polycyclic Aromatic Hydrocarbons resulting from Anisotropic Illumination

, 2009
We study the polarized infrared emission by Polycyclic Aromatic Hydrocarbons (PAHs), when anisotropically illuminated by UV photons. PAH molecules are modeled as planar disks with in-plane and out-of-plane vibrational dipoles.

A Review on the Atmospheric Concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) in Asia Since 2000 - Part I: Data from Developed Countries

Asian Journal of Atmospheric Environment, 2012
Among all hazardous air pollutants, polycyclic aromatic hydrocarbons (PAHs) are more significant owing to their carcinogenic, mutagenic and teratogenic properties.

MagNanoTrap Enrichment Empowers Ultra‐Sensitive Quantification of Mixed Nanoplastic Particles From Environmental Water Samples

Angewandte Chemie International Edition, EarlyView.
Fe3O4 nanoparticles coated with the bifunctional peptide LCI‐DZ‐MBP1, where LCI binds the iron oxide surface and MBP1 acts as a universal plastic‐binding peptide, combined with pyrolysis‐gas chromatography/mass spectrometry (Py‐GC/MS), enable efficient enrichment, precise detection, and quantification of mixed plastics (PS, PE, PP, PET, PMMA, PC, Nylon

On the Aliphatic versus Aromatic Content of the Carriers of the "Unidentified" Infrared Emission Features

, 2016
Although it is generally accepted that the so-called "unidentified" infrared emission (UIE) features at 3.3, 6.2, 7.7, 8.6, and 11.3 micrometer are characteristic of the stretching and bending vibrations of aromatic hydrocarbon materials, the exact ...

A Comparison of Particulate-Bound Polycyclic Aromatic Hydrocarbons Long-Range Transported from the Asian Continent to the Noto Peninsula and Fukue Island, Japan

Asian Journal of Atmospheric Environment, 2018
This is the first comparative study to examine two different background monitoring sites in Japan to compare differences in the concentration and composition of long-range-transported polycyclic aromatic hydrocarbons (PAHs) from the Asian continent. This

The hydrogen coverage of interstellar PAHs [PDF]

The rate at which the CH bond in interstellar Polycyclic Aromatic Hydrocarbons (PAHs) rupture due to the absorption of a UV photon has been calculated. The results show that small PAHs (less than or equal to 25 carbon atoms) are expected to be partially ...

Removal of PAHs from n-Paraffin by Modified Clinoptilolite [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2007
The ability of natural clinoptilolite and its modified forms were studied for removal of PAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. Homoionic forms of zeolite were
