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?

Jeffrey Brent et al.

Clinical toxicology (Philadelphia, Pa.), 51(4), 195-198 (2013-04-06)

Hypoxia-inducible factor-1β (HIF-1β) is upregulated in a HIF-1α-dependent manner in 518A2 human melanoma cells under hypoxic conditions.

Markus Mandl et al.

Biochemical and biophysical research communications, 434(1), 166-172 (2013-04-02)

Solid tumors include hypoxic areas due to excessive cell proliferation. Adaptation to low oxygen levels is mediated by the hypoxia-inducible factor (HIF) pathway promoting invasion, metastasis, metabolic alterations, chemo-resistance and angiogenesis. The transcription factor HIF-1, the major player within this

Hypoxia and cytoplasmic alkalinization upregulate growth hormone expression in lymphocytes.

Douglas A Weigent

Cellular immunology, 282(1), 9-16 (2013-05-04)

We report here that culture of lymphoid cells under hypoxic conditions showed an increase in both luciferase expression from a GH-promoter luciferase construct and the levels of lymphocyte GH. The effect was mimicked by treatment of cells with cobalt chloride

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
