Amyloidosis: Modern Cross-sectional Imaging.

Amyloidosis is a rare diverse condition caused by the pathologic extracellular deposition of abnormal insoluble proteins throughout the body. It may exist as a primary disease or, more commonly, may be secondary to a wide variety of pathologic processes ranging from chronic infection or inflammation to malignancy. Hereditary forms also exist.

Cardiac fibrogenesis following infarction in mice with deletion of inducible nitric oxide synthase.

Background: Studies have shown that the absence of inducible nitric oxide synthase (iNOS) improves cardiac function and survival after myocardial infarction (MI). The responsible mechanisms, however, remain uncertain. Cardiac iNOS is significantly increased after MI, which is colocalized with fibrous tissue formation.
