CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

Impact strength for notched high strength steel.

open access: yesJournal of the Society of Materials Science, Japan, 1985
An instrumented impact charpy test was carried out to evaluate the effects of the notch shape, hardness, and carburized depth on the impact bending strength of notched high strength steels (SCM 440 and SCM 415 steels).The principal results were as follows:(1) The impact bending strength of the notched high strength steel was in near proportion to the ...
