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.
Microcotyle victoriae
"Microcotyle victoriae" was first described by Woolcock in 1936. In the same paper, Woolcock re-examined "Microcotyle bassensis" and included essential data of its structure and measurements, and described a second new species "Microcotyle sillaginae" from the gills of "Sillaginodes punctatus" (Sillaginidae). The latest monogenean is currently included in the genus "Polylabris." 
In 1971, "Microcotyle victoriae" was included in the subgenus "Microcotyle" as "Microcotyle" ("Microcotyle") "victoriae".
This species was transferred by Caballero & Bravo-Hollis to the genus "Paramicrocotyle" as "Paramicrocotyle victoriae" n. comb. Mamaev, in his revision of the family Microcotylidae, suppressed this combination, reassigned the species to the genus "Microcotyle" as "Microcotyle victoriae" and considered "Paramicrocotyle" a junior subjective synonym of "Microcotyle".
