Modulation of anti-tumour functions of NK cells and macrophages after single low-level exposures of mice to X-rays
Based on the reports suggesting that exposures to low doses of ionising radiation may impede tumour development and/or trigger the activity of natural anti-neoplastic defence mechanisms we demonstrate in the present study that single whole-body irradiations of mice with 0.1 or 0.2 Gy X-rays significantly decreased the number of the induced tumour colonies in the lungs and that the effect was ...

Expanded and Activated Natural Killer Cells for Immunotherapy of Hepatocellular Carcinoma
Abstract Viral infection of the liver is a major risk factor for hepatocellular carcinoma (HCC). Natural killer (NK) cells recognize virally infected and oncogenically transformed cells, suggesting a therapeutic role for NK-cell infusions in HCC. Using the K562-mb15-41BBL cell line as a stimulus, we obtained large numbers of activated NK cells from the peripheral blood of healthy donors. ...

Effect of heat treatment of nano-hydroxyapatite coatings prepared using electrohydrodynamic deposition
Electrohydrodynamic spraying has recently emerged as a powerful method of producing nano-structured hydroxyapatite (nHA) coatings for biomedical implants. To enhance the mechanical properties of these coatings, a subsequent heat treatment is normally needed. However, whether this process significantly influences the coated surface morphology and cellular responses still needs to be systematically ...
