The effect of pharmaceutical composition based on L-carnitine on structural and functional features of rat placenta in the model of passive tobacco smoking by I.V. Volokhov, V.A. Rybak, L.Yu. Sergienko, S.S. Sokolova, S.P. Kustova

“…The use of a pharmaceutical composition based on L-carnitine at a dose of 25 mg/kg in pregnant rats with a reproduced model of passive smoking reduces the damaging effect of cigarette combustion products on placental steroidogenesis. This is manifested by a less pronounced decrease in progesterone levels by 22.47% and free estriol by 55.48% compared to animals exposed to passive smoking, which almost corresponds to the activity of the reference drug at a dose of 68 mg/kg. …”

Sources and Health Risks of PM2.5-bound PAHs in a Small City along with the “Clean Heating” Policy by Zhiyong Li, Ziyuan Yue, Jixiang Liu, Zhen Zhai, Jianwei Meng, Lei Wang, Jihong Wei, Dingyuan Yang, Ailian Hu, Wenjia Zhu, Ning Ding, Xiaoxia Lu, Chunhao Lin

“…Positive matrix factorization (PMF) demonstrated that biomass/natural-gas burning (BNGB) contributed most to PAHs of 36.9% in the HS, the increased natural gas (NG) usage for heating should be responsible for this contribution due to the policies of biomass-burning prohibition and “Coal to Gas”. Coal combustion (CC) shares increased by 152% in the HS despite the “Coal Banning” project. …”
