*Plagiarism* is copying the work of another person...whether it be their exact words or paraphrasing their ideas. Collecting data is not plagiarism, nor is asking for advice on where to find articles or accepting suggestions for articles to use as research.
You can tell that this person is not from the United States and does not realize what type of forum this is....as it seems to be directed at a doctor.
If you would like to find articles on this topic, you will need to search for them at your college/university library or online in their database. You need passwords and IDs to get into these sites, otherwise you will not be able to view any of the material.
dito what Rockrose said....you need to do your own research. It's unethical to get others to help you with your research and if you did, you would not be able to take credit for it...otherwise it's plagarism. Not sure where you are located, but at most schools, universities, etc, plagarism is grounds for expulsion.
I suggest you learn how to do your own research.
