| Pathogenesis is the development of disease, from the initial appearance of disease all the way to its end stages. It is a multi-factorial process which depends on the immune status of the host, the nature of the species or strain (virulence factors) and the number of organisms in the initial exposure. The study of pathogenesis is important for medical professionals, as it helps them identify and treat diseases. It is also part of the work of laboratory sciences who work on cures and treatments for diseases, as each stage of pathogenesis represents a potential possibility for interrupting the progression of the disease.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
