7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN …

Tests on Aggregate Aggregate plays an important role in pavement construction. Aggregates influence, to a great extent, the load transfer capability of pavements. Hence it is essential that they should be thoroughly tested before using for construction. Not only that aggregates should be strong and durable, they should also possess proper shape and size to […]

Aggregates of NAC‐related peptides are toxic to the cell (El‐Agnaf et al. 1998c; Bodles et al. 2000, 2001). All this suggests that the accumulation of NAC and C‐terminally truncated α‐synuclein aggregates in the synapse may be responsible for, or at least associate with, the neurodegeneration observed in different synucleinopathies.
