Biomedical Implant Devices Fabricated from Low Young’s Modulus Titanium Alloys Demonstrating High Mechanical Biocompatibility

Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as bones and teeth.

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
