Chimera

In zoology, a chimera is an animal that has two or more different populations of genetically distinct cells that originated in different zygotes; if the different cells emerged from the same zygote, it is called a mosaicism.

Chimeras are formed from four parent cells (two fertilized eggs or early embryos fuse together) or from three parent cells (a fertilized egg is fused with an unfertilized egg or a fertilized egg is fused with an extra sperm). Each population of cells keeps its own character and the resulting animal is a mixture of mis-matched parts. An analogy is two jigsaw puzzles cut using an identical cutter, but with different pictures. A single puzzle can be made out of the mis-matched parts, but the completed puzzle will show parts of both pictures.

This condition is either acquired through the infusion of allogeneic hematopoietic cells during transplantation or transfusion or it is inherited. In fraternal twins, chimerism occurs by means of blood-vessel anastomoses. The likelihood of a child being a chimera is increased if the child is created via in vitro fertilization. Chimeras can often breed, but the fertility and type of offspring depends on which cell line gave rise to the ovaries or testes.

What Is Chiari (Kiari) Malformation Disease?

The Post Chronicle - Chiari disease is a complex group of disorders that are characterized by a herniation of the cerebellum through the large opening in n the base of the skull (foramen magnum) into the spinal canal.

Chiari is often misspelt as Kiari, phonetically both sounds the same. There are three main types of Chiari Malformation. CM1, the simplest and most prevalent form, is generally considered to be a congenital malformation, although acquired cases are recognized. (See diagrams below.) It is rarely apparent at birth. CM2 and CM3 are more severe congenital malformations that are apparent at birth and associated with complex defects of the brain and spinal cord.
