|Signal Transduction is the way by which cells respond to extracellular signalling molecule which activates a specific receptor located on the cell surface or inside the cell. The study on signal transduction focuses on the mechanism by which cells, tissues and organisms respond to different stimuli and different factors responsible for the regulation and prevention of Signal transduction, responses of cells to many environmental stimuli leads to diverse aspects of human health and cause diseases like cystic fibrosis, diabetes, cancer, asthma and autoimmune diseases. 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.
