Distinctive gene expression profiles in Balb/3T3 cells exposed to low dose cobalt nanoparticles, microparticles and ions: potential nanotoxicological relevance.

S Perconti et al.

Journal of biological regulators and homeostatic agents, 27(2), 443-454 (2013-07-09)

Size-dependent characteristics of novel engineered nanomaterials might result in unforeseen biological responses and toxicity. To address this issue, we used cDNA microarray analysis (13443 genes) coupled with bioinformatics and functional gene annotation studies to investigate the transcriptional profiles of Balb/3T3

Unique ligand-radical character of an activated cobalt salen catalyst that is generated by aerobic oxidation of a cobalt(II) salen complex.

Takuya Kurahashi et al.

Inorganic chemistry, 52(7), 3908-3919 (2013-03-23)

The Co(salen)(X) complex, where salen is chiral N,N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamine and X is an external axial ligand, has been widely utilized as a versatile catalyst. The Co(salen)(X) complex is a stable solid that has been conventionally described as a Co(III)(salen)(X) complex. Recent

Dilemmas about the toxicological consequences of metal-on-metal hip prostheses -- What we do and do not know, and what we should do?

Metal ion levels and lymphocyte counts: ASR hip resurfacing prosthesis vs. standard THA: 2-year results from a randomized study.

Jeannette Ø Penny et al.

Acta orthopaedica, 84(2), 130-137 (2013-04-20)

Wear particles from metal-on-metal arthroplasties are under suspicion for adverse effects both locally and systemically, and the DePuy ASR Hip Resurfacing System (RHA) has above-average failure rates. We compared lymphocyte counts in RHA and total hip arthroplasty (THA) and investigated

Adverse local tissue reaction arising from corrosion at the femoral neck-body junction in a dual-taper stem with a cobalt-chromium modular neck.

H John Cooper et al.

The Journal of bone and joint surgery. American volume, 95(10), 865-872 (2013-05-17)

Femoral stems with dual-taper modularity were introduced to allow additional options for hip-center restoration independent of femoral fixation in total hip arthroplasty. Despite the increasing availability and use of these femoral stems, concerns exist about potential complications arising from the
