Wear behaviour of UHMWPE reinforced by carbon nanofiller and paraffin oil for joint replacement.

The majority of artificial joints incorporate biomedical grade Ultra High Molecular Weight Poly Ethylene (UHMWPE), whose wear is considered most important in controlling service time of the whole joint. The aim of this work was to improve wear resistance of UHMWPE through the addition of 0.5-2.

[Work related disease in radiation exposed? Case report].

In the present work we analysed the possible recognition of professional disease in a subject exposed to ionizing radiation. Haematic parameters were evaluated during the working activity and after the risk's avoidance. Normal haematic values after the pathogenic noxa's avoidance exclude a chronic damage, which in an indispensable datum for professional disease recognition.
