BACKGROUND Recent studies demonstrated an impact of the nervous system on particle-induced osteolysis, the major cause of aseptic loosening of joint replacements. METHODS In this study of MG-63 osteoblast-like cells we analyzed the influence of ultra-high molecular weight polyethylene (UHMWPE) particles and the neurotransmitter alpha-calcitonin gene-related peptide (CGRP) on the osteoproteger...

Introduction: Alpha particle emitters are very damaging and harmful when entering into the human body ,if   ingested or inhaled , swallowed or absorbed  into the lungs or bloodstream . Uranium (238U), Radium (226Ra) and Radon (222Rn) are typical alpha-particle emitters. Material and Methods: we measured the level of alpha particles emitted from 222Rn, 226Ra, and 238U in blood samples of 10 can...

A round up of the present status of the conjecture that nα nuclei form an αparticle condensate in excited states close to the nα threshold is given. Experiments which could demonstrate the condensate character are proposed. Possible lines of further theoretical developments are discussed. In this article we want to report on the present status of our recent conjecture [1] that at least light nα...

An approximate but straight forward projection method to molecular many alpha-particle states is proposed and the overlap shell model space determined. The resulting in accordance with model, still contains which are not completely symmetric under permutations of alpha-particles, one reason call construction semi-microscopic. A new contribution 6- 7-$\alpha$-particle spaces. errors propagate to...
