Posterior pain may be caused from internal impingement of the posterior capsular or labrum. This technique allows posterior fixation of intraocular lens implants in the absence of capsular support. The production of a capsular polysaccharide decreases biofilm formation. The second is K antigen, a capsular polysaccharide with more than 80 varieties. Certain strains of "S. haemolyticus" are capable of producing a capsular polysaccharide (CP). These bundles are referred to as the capsular ligament. A Quellung test can identify specific capsular polysaccharides. Mixtures of capsular polysaccharides, either conjugated or native are used as vaccines. Encapsulated strains were classified on the basis of their distinct capsular antigens. Four different stages are distinguished on radiological evidence of synovitis, joint space and capsular laxity. The central nucleus also has three subnuclei&colon; lateral, capsular, and medial. "P. gingivalis" is divided into K-serotypes based upon capsular antigenicity of the various types. In prostate cancer brachyury expression is associated with Gleason score, perineural, invasion and capsular invasion. Symptoms may occur suddenly, progressively, or in a fluctuating (e.g., the capsular warning syndrome) manner. Capsular ligaments are part of the articular capsule that surrounds synovial joints.
