Microglia
Research has discovered dystrophic (defective development) human microglia. "These cells are characterized by abnormalities in their cytoplasmic structure, such as deramified, atrophic, fragmented or unusually tortuous processes, frequently bearing spheroidal or bulbous swellings." The incidence of dystrophic microglia increases with aging. Microglial degeneration and death have been reported in research on Prion disease, Schizophrenia and Alzheimer's disease, indicating that microglial deterioration might be involved in neurodegenerative diseases. A complication of this theory is the fact that it is difficult to distinguish between "activated" and "dystrophic" microglia in the human brain.
Caladenia microchila
"Caladenia microchila" was first described in 2001 by Stephen Hopper and Andrew Phillip Brown and the description was published in "Nuytsia". The specific epithet ("microchila") is derived from the Ancient Greek words "mikros" meaning "small" and "cheilos" meaning "lip" referring to the relatively small labellum of this species.
