|Transplantation is the transfer of essential cells, organs or tissues from one location to another with in a same person or from one individual to the other for the purpose of replacing damaged or absent organs in patients. Many of the diseases which will not be readily curable by different types of treatments can be cured by this technique of transplantation. Transplantation technique can be mainly divided into two types called allograft transplantation and autograft transplantation. Autograft transplantation is a transplantation which is performed within the same person by transferring organs or tissues from one place to another within the same body, whereas allograft transplantation is a transplantation which is performed between two different individuals or between two species. There are different types of transplantations depending up on the type of transplant. Heart, kidney, liver, lung, pancreas, intestine, and thymus will come under organ transplantation and bones, cornea, skin, heart valves, nerves and veins will come under tissue transplantation. There are different types of transplantations and the most commonly transplanted organs are kidneys which are followed by liver and heart. Transplantation has become a clinical practice and a strategy for overcoming many diseases which will not be readily curable by any existing therapies. 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.
