Turning up in Galata, no end of new arrivals (8)
I believe the answer is:
neonatal
'of new arrivals' is the definition.
(I've seen this in another clue)
'turning up in galata no end' is the wordplay.
'turning up' says the letters should be written in reverse.
'in' says the answer is hidden in the clue.
'latanoen' is hidden in the letters of 'galata no end'.
'latanoen' backwards is 'NEONATAL'.
(Other definitions for neonatal that I've seen before include "Of a new-born infant" , "at a very young age" , "of newborn babies!" , "Relating to the first month of life" , "Like clinic" .)
