The Relationship between Rest Tremor and Underlying Lewy Pathology in Essential Tremor: A Clinical‐Pathological Study of 201 Cases

Annals of Neurology, EarlyView.
Objectives Prospective studies demonstrated that essential tremor is a risk factor for Parkinson's disease. Identifying clinical markers for conversion from essential tremor to essential tremor‐Parkinson's disease would be of considerable value. Rest tremor can be present in advanced essential tremor and may be a harbinger of conversion. We examined (1)

Sex Differences in Associations of Lewy Body Disease with Alzheimer's Disease and Cognitive Decline

Annals of Neurology, EarlyView.
Objective To investigate how sex and age at menopause influence the interplay between Alzheimer's disease (AD) and Lewy body disease (LBD) neuropathologies, and their associations with cognitive decline. Methods We analyzed data from: (1) three Rush Alzheimer's Disease Center cohorts (i.e., the Religious Orders Study, Rush Memory and Aging Project, and

Transcranial Sonography of the Substantia Nigra: Digital Image Analysis

American Journal of Neuroradiology, 2014
BACKGROUND AND PURPOSE: Increased echogenicity of the substantia nigra is a typical transcranial sonography finding in Parkinson disease. Experimental software for digital analysis of the echogenic substantia nigra area has been developed.

What does it mean? Translating anatomical language to engage public audiences

Anatomical Sciences Education, EarlyView.
Abstract The language of anatomy, with its roots in Ancient Greek and Roman languages, is complex and unfamiliar to many. Its complexity creates a significant barrier to public knowledge and understanding of anatomy—many members of the public find themselves asking “what does it mean?”, and this can manifest as poor health literacy and outcomes.

Physics of Protein Aggregation in Normal and Accelerated Brain Aging

BioEssays, EarlyView.
Soluble monomeric proteins precipitate via nucleation into insoluble amyloids in response to age‐related exposures (e.g., microbes, nanoparticles). Persistent soluble‐to‐insoluble phase transition depletes the functional proteins. In normal aging, replacement matches loss; in accelerated aging, it does not.

Serotonergic Modulators in Alzheimer's Disease: A Hope in the Hopeless Condition

Chemistry &Biodiversity, EarlyView.
ABSTRACT Alzheimer's disease (AD) is the main cause of dementia worldwide. AD is a progressive brain neurodegenerative disease due to genetic and environmental factors that induce a progressive accumulation of intracellular hyperphosphorylated tau protein and extracellular amyloid protein (Aβ).

Probing the Inhibitory Potential of Halogenated Symmetrical Formamidine Against MAO‐A and MAO‐B: Structural Elucidation, Molecular Dynamic Simulation and DFT Computational Studies

Chemistry &Biodiversity, EarlyView.
ABSTRACT A halogenated symmetrical formamidine, N,N′‐bis(3‐chloro‐4‐fluorophenyl)formamidine (FCF) was synthesized by the condensation reaction between triethyl orthoformate and 3‐chloro‐4‐fluoroaniline in 1:2 ratio. The compound FCF was characterized by FT‐IR, mass, NMR (1H and 13C) spectroscopic techniques and the purity was confirmed by elemental ...

Synthesis and Biological Characterization of 4,4‐Difluoro‐3‐(phenoxymethyl)piperidine Scaffold as Dopamine 4 Receptor (D4R) Antagonist in vitro Tool compounds

ChemMedChem, EarlyView.
The work presents details of the efforts to design and characterize novel D4 inhibitors. A new 4,4‐difluoropiperidine ether series that confers improved potency and selectivity for D4 versus the other dopamine receptor subtypes is identified. Extensive structure‐activity relationship around this privileged group identifies the key structural changes to

Manganese Neurotoxicity and Familial Disorders of Manganese Transport

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Manganese is the 12th most common element in the Earth's crust and is an essential industrial component. Biologically, this metal plays an important role as a constituent of numerous enzymes. While manganese is required for normal biochemical and physiological processes, manganese excess can lead to significant toxicity, particularly to the ...
