Myelin Structure and Composition in Zebrafish

Organization and structure in central-nerve myelin.

Degeneration of the myelin sheath in areas of the central nervous system is a characteristic feature of multiple sclerosis (Adams, 1977; Davison, 1978). The processes that cause this degradation of myelin during the course of the disease are not yet fully defined though the involvement of invading inflammatory cells is likely (Wisniewski, 1977). Any discussion on how the myelin sheath is attack...

The structure of bovine brain myelin proteolipid and its organization in myelin.

A model, based on amino acid sequence data, is proposed for the organization of the myelin proteolipid in myelin membrane. The model has three distinctive features: three trans-membrane segments that traverse the lipid bilayer, two cis-membrane domains that enter and exit the same side of the membrane, and a highly charged segment resembling myelin basic protein on the cytoplasmic side of the m...

A screen for mutations in zebrafish that affect myelin gene expression in Schwann cells and oligodendrocytes.

Myelin is the multi-layered glial sheath around axons in the vertebrate nervous system. Myelinating glia develop and function in intimate association with neurons and neuron-glial interactions control much of the life history of these cells. However, many of the factors that regulate key aspects of myelin development and maintenance remain unknown. To discover new molecules that are important f...

Atmospheric Structure and Composition,

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
