Abstract: Some of the mitochondria in the free-living giant ameba Pelomyxa carolinensis (Chaos chaos) exhibit unusual and strikingly complex morphological patterns. A study of serial sections of these mitochondria reveals that the patterns are formed by the organization and packing of minute villi (cristae mitochondrlales). The form of the individual villus is a regular soft zigzag (or wave) with a bulbous enlarge-ment at each point of inflection ("elbow") on the wave. The pattern of the mito-chondria may become increasingly complex as a result of branching and fusing of the wavy villi. Densely packed fibrillar material is sometimes present in the stroma of the mitochondria.

- Diabetic kidney failure follows a 'ROCK'y road
A protein kinase known as ROCK1 can exacerbate an important process called fission in the mitochondria, the power plants of cells, leading to diabetic kidney disease, said researchers from Baylor College of Medicine in a report that appears online today in the journal Cell Metabolism.
