[edit] Or you can just click the very tiny "PDF" link on the linked page that I apparently missed the first time.

keep in mind this is a preliminary, the grammar used in this paper needs to be revised so as to avoid as much as possible, people coming to errant conclusions after misinterpreting poorly written phrases.

so that means that while reading this paper one should not skim but should take the effort to interpret this paper.

there is an absence of references in the abstract, this makes it hard to examine the basis for statements in abstract

if you head down to page 4 of the paper there is where you will find references to background literature cited regarding "neuroinvasive potential"
