Metabolic correlates of prevalent mild cognitive impairment and Alzheimer's disease in adults with Down syndrome. [PDF]

open access: yes, 2020
IntroductionDisruption of metabolic function is a recognized feature of late onset Alzheimer's disease (LOAD). We sought to determine whether similar metabolic pathways are implicated in adults with Down syndrome (DS) who have increased risk for ...

Quantitative proteomics identifies clusterin as a novel biomarker for atherosclerosis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This schematic illustrates the proposed mechanism. In advanced atherosclerotic lesions, upregulated CLU on the cell surface activates low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1). This interaction triggers the phosphorylation and activation of AKT.

Apolipoprotein E delivery by peritoneal implantation of encapsulated recombinant cells improves the hyperlipidaemic profile in apoE-deficient mice [PDF]

open access: yes, 2005
Plasma apolipoprotein E (apoE) is a 34-kDa polymorphic protein which has atheroprotective actions by clearing remnant lipoproteins and sequestering excess cellular cholesterol.

Knowledge means 'all', belief means 'most'

open access: yes, 2012
We introduce a bimodal epistemic logic intended to capture knowledge as truth in all epistemically alternative states and belief as a generalized 'majority' quantifier, interpreted as truth in many (a 'majority' of the) epistemically alternative states.

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

open access: yesAnnals of Neurology, EarlyView.
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 ...

Chronological Diagnostic Algorithm Predicting Neuropathology in Parkinsonism

open access: yesAnnals of Neurology, EarlyView.
Objective Pre‐mortem diagnosis of parkinsonism is often challenging due to atypical presentations, overlapping syndromes, and co‐pathologies. This study aimed to develop a machine learning‐based algorithm predicting neuropathology in parkinsonism using chronological clinical presentations, which has previously been underexplored.

Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

open access: yesAnnals of Neurology, EarlyView.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐

APOE suppresses osteosarcoma by modulating ferroptosis through the mTOR/Stat3 signaling pathway

open access: yesArchives of Medical Science
Introduction Osteosarcoma (OS) is a highly malignant bone tumor with limited treatment options. The role of apolipoprotein E (APOE) in OS remains unclear.
