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. Gene therapy is an experimental technique in which with the usage of genes the diseases are treated. whereas gene therapy is now a day’s approaching as a precious remedy for number of infections (including inherited disorders, some types of cancer, and certain viral infections), but then also the method remains unreliable and is still under study to make sure that it will be safe and productive. Currently, gene therapy is only being checked for the treatment of diseases that have no other remedy choices. Most often, the employed of gene therapy is based on inserting a healthy wholesome exact replicate of a defective gene into the patient's units to make the functional protein. If any mutated gene causes essential protein to be defective or missing, gene treatment may be used to insert a usual exact replicate of the gene to replenish the function of the protein. When a gene is inserted directly into a cell it usually does not function correctly. Instead, a carrier called a vector is genetically engineered to deliver the gene
