Toxicol Rep . 2017 Oct; 2:1404-1408. PMID: 28962481
The fetal toxicities of multi-wall carbon nanotubes (MWCNTs) with various sizes were compared in CD1(ICR) mice. MWCNTs were suspended in 2% sodium carboxymethyl cellulose solution in phosphate-buffered saline. On day...

Genes Environ . 2017 Jan; 39:4. PMID: 28074111
Introduction: It is known that fibrous particles of micrometer length, such as carbon nanotubes, which have same dimensions as asbestos, are carcinogenic. Carcinogenicity of nanomaterials is strongly related to inflammatory...

J Appl Toxicol . 2015 Mar; 35(12):1465-72. PMID: 25809591
DNA damage and cytotoxicity induced by a hydroxylated fullerene [C60 (OH)24 ], which is a spherical nanomaterial and/or a water-soluble fullerene derivative, and their protection by sulfhydryl compounds were studied...

Tanaka T, Ogata A, Inomata A, Nakae D
Birth Defects Res B Dev Reprod Toxicol . 2014 Oct; 101(5):393-401. PMID: 25283888
Male and female mice were housed in cages, containing different types of bedding materials (wood flakes or pulp chips), from 4 weeks of age in the F0 generation to 11...

Cui H, Wu W, Okuhira K, Miyazawa K, Hattori T, Sai K, et al.
Biochem Biophys Res Commun . 2014 Sep; 452(3):593-9. PMID: 25181346
Because multi-wall carbon nanotubes (MWCNTs) have asbestos-like shape and size, concerns about their pathogenicity have been raised. Contaminated metals of MWCNTs may also be responsible for their toxicity. In this...

J Toxicol Sci . 2014 Mar; 39(2):363-70. PMID: 24646718
Possible teratogenicity of 3 different asbestos (crocidolite, chrysotile and amosite) was assessed in CD1(ICR) mice. Dams on day 9 of gestation were given a single intraperitoneal administration at dose of...
