|Osteoarthritis is a common form of arthritis occurring in males after the age of 45 and females after the age of 55. It generally occurs through aging and not due to any particular wound or disease. With aging, the cartilage proteins, present between bones, get degenerated due to increased water content. Individuals having increased uric acid content in their body can get this disease easily due to the deposition of uric acid crystals in the cartilage that causes its degeneration. Individuals that have works of weight lifting get more affected with the disease because of the strains that arise on their knees and joints. People are sometimes born with some joints abnormalities that also grow mechanical stress in their joints.
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
