Medical journals are publications that report medical information to physicians and other health professionals.
In the past, these journals were available only in print. With the development of electronic publishing, many medical journals now have Web sites on the Internet, and some journals publish only online. A few medical journals, like the Journal of the American Medical Association, are considered general medical journals because they cover many fields of medicine. Most medical journals are specialty journals that focus on a particular area of medicine.
Medical journals publish many types of articles. Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments. Review articles summarize and analyze the information available on a specific topic based on a careful search of the medical literature. Because the results of individual research studies can be affected by many factors, combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing, diagnosing or treating a particular disease. Case conferences and case reports may be published in medical journals to educate physicians about particular illnesses and how to treat them. Editorials in medical journals are short essays that express the views of the authors, often regarding a research or review article published in the same issue. Editorials provide perspective on how the current article fits with other information on the same topic. Letters to the editor provide a way for readers of the medical journal to express comments, questions or criticisms about articles published in that journal.

Millions of copies of console and computer- based" brain trainers" are sold worldwide every year, claiming to make peoples’brains younger, better, faster or bigger. The theory seems to make sense: regularly exercising the brain with tests and puzzles can improve brain skills and help people become better at everyday thinking tasks.
But recent research suggests scientific evidence is lacking.
The BBC’s Brain Test Britain experiment wants to find out if brain training really works, and is aiming to get thousands of members of the public to train for 10 minutes a day ,three times a week ,for at least six weeks.
Scientific experiments and their findings should be evaluated by independent experts in a process called "peer review". This is the minimum standard by which the quality of any research is judged.
Very little research on commercial brain trainers has been peer reviewed.
Instead, manufacturers often quote unsupported testimonials from" satisfied users". None of these are acceptable substitutes for peer review.
A proper" control group" is the backbone of any valid scientific study.
With a brain training study, the control group of participants should do the same amount of a mental activity as the brain - training group, but using a" non - brain training" activity such as a crossword.
Scientists should then be able to compare the results from the two groups to see how genuinely effective the brain training tasks were.
Studies that have been used to support the claims made by commercial brain trainers often have no control group at all, or a control group that is not as mentally active as the trained group.
In order to see how much you have improved, you need to know where you were at the start. To do this. scientists use a" benchmarking test"—the same test, taken at the beginning and end of an experiment.
Benchmarking tests should he different from the brain training tasks. This way, scientists can see if the effects of brain training are transferable to other mental tasks.
Studies used to support the claims made by commercial brain trainers often use tests for benchmarking that are identical—or very similar—-to the tests used during training
Which statement about" peer review" is right

A:The testimonials from" satisfied users" of a product can be classified as peer review. B:A good scientific research must go through a" peer review". C:Peer review can be done by the researchers who do the experiment. D:An the existent brain trainer products have a peer review to testify their quality.
