Design and control of a novel variable stiffness soft arm [PDF]

, 2018
Soft robot arms possess such characteristics as light weight, simple structure and good adaptability to the environment, among others. On the other hand, robust control of soft robot arms presents many difficulties.

Abnormal amyloid PET usually represents intermediate/high Alzheimer's disease neuropathologic change

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Alzheimer's disease neuropathologic change (ADNC) classification identifies not/low and intermediate/high levels of neuropathology. Our goal was to assess how frequently a positive amyloid positron emission tomography (PET) scan indicates not/low ADNC and whether this autopsy finding can occur >10 years after a positive amyloid ...

Effects of α‐synuclein pathology on synaptic dysfunction and clinical outcomes in normal aging

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION α‐Synuclein is the hallmark pathology of Parkinson's disease and dementia with Lewy bodies, described together as Lewy body disease (LBD). We investigated effects of α‐syn biomarker positivity in clinically unimpaired (CU) individuals.

When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

Annals of Neurology, Volume 99, Issue 5, Page 1327-1342, May 2026.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

APOE4 Drives Sex‐ and Diet‐Dependent Effects on AD‐Like Pathology, Cognition, and Mitochondrial Function

FASEB BioAdvances, Volume 8, Issue 5, May 2026.
APOE4 interacts with sex and diet to influence brain mitochondrial function. ABSTRACT Apolipoprotein E4 (APOE4) is the strongest genetic risk factor for Alzheimer's disease (AD), yet it's unclear how this allele promotes disease. While factors like diet and sex may modify AD susceptibility in APOE4 carriers, the interaction between these factors is ...
