    The Role of pH in PEG-b-PAAc Modification of Gadolinium Oxide Nanostructures for Biomedical Applications by Eva Hemmer, Nallusamy Venkatachalam, Hiroshi Hyodo, Kohei Soga

    Published 2012-01-01
    “…It was shown that PEG-b-PAAc (poly(ethylene glycol) poly(acrylic acid) block polymer) is suitable to provide the required chemical durability, dispersion stability, and noncytotoxic behaviour for biomedical applications, where the coating of Gd2O3 with a protecting and biocompatible layer is essential in order to prevent the release of toxic Gd3+ ions. Physicochemical properties of the Gd2O3:Er3+,Yb3+ nanostructures modified with PEG-b-PAAc have been investigated by TG-DTA, FT-IR, and DLS revealing a strong influence of modification conditions, namely, pH of the reaction media, on the nature of the PEG-b-PAAc layer.…”

    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. …”
