    Significant Removal of Harmful Compounds in Mainstream Cigarette Smoke Using Carbon Nanotubes Mixture Prepared by Catalytic Pyrolysis by Shun Zhou, Min Ning, Yaping Zhang, Qing He, Xiaofeng Wang, Dongliang Zhu, Song Guo, Ningning Hong, Yuan Hu

    Published 2014-06-01
    “…After introducing 15 mg of CNTM into cigarette filter, some of the most important harmful compounds including tar, nicotine, benzo[a]pyrene (B[a]P) and phenolic compounds were more efficiently adsorbed in comparison with using commercial activated carbon, which can be related to the relatively bigger pore volume and a geometric confinement of CNT in CNTM for some toxic compounds in cigarette smoke. In particular, CNTs have a strong chemisorption capacity for B[a]P or phenolic compounds due to the π–π interactions between benzene rings.…”

    Endothelin receptor antagonists (ERAs) can potentially be used as therapeutic drugs to reduce hypertension caused by small molecule tyrosine kinase inhibitors (TKIs) by Qingjian He, Junling Lin, Chanjuan Mo, Guodong Li, Jianzhong Lu, Qiyin Sun, Lijun Cao, Haojian Gan, Quan Sun, Jiafang Yao, Shengyi Lian, WenJuan Wang

    Published 2025-01-01
    “…Among these drugs, vascular endothelial growth factor (VEGF) inhibitors, particularly novel small molecule tyrosine kinase inhibitors (TKIs), are extensively employed as VEGF inhibitors; however, they are also associated with a higher incidence of complications, with hypertension being the most prevalent cardiovascular toxic side effect. Currently, it is widely accepted that TKIs-induced hypertension involves multiple mechanisms including dysregulation of the endothelin (ET) axis, reduced bioavailability of nitric oxide (NO), imbalance in NO-ROS equilibrium system, vascular rarefaction, and activation of epithelial sodium calcium channels; nevertheless, excessive activation of ET system appears to be predominantly responsible for this condition. …”

    Sedum alfredii Hance: A cadmium and zinc hyperaccumulating plant by Mingying Liu, Ying Feng, Miao Wang, Xinglin Sun, Chen Yinfei Qi, Xiaoe Yang, Dayi Zhang

    Published 2025-01-01

Numerous studies have been conducted to uncover the mystery of its hypertolerance and hyperaccumulation using high-throughput sequencing, biochemical and molecular techniques, mainly pointing to the root-microorganism interaction, restrained Cd storage in roots, efficient root-shoot translocation, effective cellular detoxification, and phloem-mediated metal remobilization. …”
