“The nanostructure reveals paired smaller fibrils that appear in optical microscopy as a single fibril.”

“As the number of fibrils decreases, it becomes increasingly easier to cut the next fibril because the fibrils carry larger and larger loads.”

“Amyloid fibril formation generally is a result of alteration of the native conformation.”

“The resultant irregular rhythm may be difficult to differentiate from atrial fibrillation.”

“It is not uncommon for this rhythm to progress into atrial flutter or atrial fibrillation.”

“Wide concern has been expressed that when such criteria are used, atrial fibrillation is being undertreated in elderly people.”

“The cells of the outer annulus are thin and extended along the collagen fibrils, rather like tendon cells.”

“These form all kinds of agglomerates and aggregates, including fibrils, in a precise morphological hierarchy.”

“Images of dissected tendon taken under the light microscope show that fibrils can sustain sharp bends or kinks along their length.”
