Acute proliferative glomerulonephritis. Acute proliferative glomerulonephritis is a disorder of the glomeruli (glomerulonephritis), or small blood vessels in the kidneys.
Syncopation is created when the accent is shifted to a weak beat or an offbeat. But this term applies to music...
If you have a meter of 4 beats to the bar, beats 1 and 3 normally receive the greatest emphasis. A syncopation might involve an unexpected accent on beat 4, or on a note in between the 3rd and 4th beat. NOTE: syncopation is not a term we use much, since its meaning is supplanted by rhythmic contrast.
