Combined subchronic toxicity of aluminum (III), titanium (IV) and silicon (IV) oxide nanoparticles and its alleviation with a complex of bioprotectors
SYNOPSIS
Aluminum nanoparticles are toxic on their own and in combination with other metal nanoparticles.

SUMMARY
The use of nanoparticles—including metallic nanoparticles—has exploded in industry, commerce and medicine over the past several decades. A Russian research team assessed the “nano-toxicity” of three types of metal nanoparticles (titanium, silicon and aluminum oxide) alone and in combination. Repeated injection into rats showed that all three were “toxic for several target organs.” However, “for the majority of these effects,” the aluminum oxide nanoparticles “proved to be the most noxious,” even though the aluminum dose was half that of the titanium and silicon doses. No other publications have reported on these metal nanoparticles’ combined toxicity, despite their “potentially hazardous nano-impacts on human health.”
New Quality-Control Investigations on Vaccines: Micro- and Nanocontamination
SYNOPSIS
Italian scientists find unexpected contaminants in all pediatric vaccines, including lead, stainless steel, tungsten, iron, and chromium

SUMMARY
Scientists found contaminants in all vaccines that are not listed on the label of the vaccines. “The analyses carried out show that in all samples checked vaccines contain non biocompatible and bio-persistent foreign bodies which are not declared by the Producers, against which the body reacts in any case. This new investigation represents a new quality control that can be adopted to assess the safety of a vaccine. Our hypothesis is that this contamination is unintentional, since it is probably due to polluted components or procedures of industrial processes (e.g. filtrations) used to produce vaccines, not investigated and not detected by the Producers. If our hypothesis is actually the case, a close inspection of the working places and the full knowledge of the whole procedure of vaccine preparation would probably allow to eliminate the problem.”
