PDT is a treatment that uses photosensitizing agent, and a specific type of light. These photosensitizing agents are exposed to light of specific wavelength such that it can determine to what extent light can travel in the body. Thus, photosensitizing agents and light of specific wavelength are used by the doctors to treat different areas of the body with PDT.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
