[18F]Fluorodeprenyl‐D2 PET as a Tool to Monitor Disease Activity in GAD65‐Ab Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate [18F]fluorodeprenyl‐D2 ([18F]F‐DED) positron‐emission tomography (PET) imaging as a biomarker of disease activity in autoimmune encephalitis (AIE) associated with glutamic acid decarboxylase 65 (GAD65) antibodies. Methods [18F]F‐DED PET was performed in 25 GAD65‐AIE patients and 8 controls using dynamic (0–60 min) and ...

Cracking behavior and mechanism of gibbsite crystallites during calcination

, 2019
Cracking is one of the major contributors to the breakage of gibbsite particles during calcination, which generates superfine particles causing detrimental effects to the quality of product in the downstream smelter grade alumina production.

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

In-situ characterization of the welding velocity-dependent solidification cracking dynamics in 310S stainless steel

Materials & Design
Solidification cracking originates from strain accumulation in residual liquid films within the mushy zone. However, the influence of welding velocity on complex cracking phenomena remains insufficiently clarified.

Numerical analysis of the crack behavior interface-fiber: interfacial crack [PDF]

Material Science & Engineering International Journal, 2019
Background Numerous studies have been conducted on composite materials concerning development at the microscopic scale In addition the elaboration of composites at relatively high temperatures leads to very localized residual stresses in the fiber and the matrix in the neighborhood very close to their interface These shear stresses put the fiber ...
