Otto Werner originally defined Werner syndrome (WS) in 1904 on the basis of sclerodermalike, thin, tight skin and bilateral cataracts. WS is also known as progeria adultorum, progeria of the adult, and pangeria.
There is no difference between the terms 'paper' and 'article'. A research paper is one where an original study has been performed. A review paper may be either a narrative review, a systematic review or a meta-analysis. A narrative review is like a book chapter: it explains a topic in detail based on previously published research.
An article is considered original research if... 1  it is the report of a study written by the researchers who actually did the study. 2  the researchers describe their hypothesis or research question and the purpose of the study. 3  the researchers detail their research methods. 4  the results of the research are reported.
