Toward Harmonizing Quantification of Dopamine Neuron Imaging Biomarkers in Parkinson's Disease: The Centamine Scale

open access: yesAnnals of Neurology, EarlyView.
Objective Dopaminergic imaging is a key biomarker for both the investigation of the biology of Parkinson's disease and related synucleinopathies and the evaluation of potential therapies in clinical trials. This work presents a harmonized approach for quantifying dopaminergic molecular imaging tracers, such as [123I]ioflupane (dopamine transporter scan

Tailoring Electronic Properties of Precision Graphene Nanoribbons via Nanopore Engineering

open access: yesAngewandte Chemie, EarlyView.
Novel porous graphene nanoribbons incorporating [18]annulene nanopores, together with a nonporous GNR of identical width, have been synthesized. Spectroscopic and theoretical analyses reveal that nanopore incorporation effectively tunes their electronic properties by enlarging the bandgap, reducing charge‐carrier mobility, and modulating exciton ...

Human Brain Contusions Contain Pathogenic Transmissible Species that Induce Progressive Cognitive Decline and Tau Pathology in Mice

open access: yesAnnals of Neurology, EarlyView.
Objective Traumatic brain injury (TBI) is an established risk factor for dementia, although the underlying mechanisms remain unclear. Our previous research demonstrated that a single severe TBI in wild‐type (WT) mice induces a prion‐like form of tau (tauTBI) that spreads throughout the brain, leading to memory deficits.

Individualized Atrophy‐Based Prediction of Dementia Progression in Familial Frontotemporal Lobar Degeneration With Bayesian Linear Mixed‐Effects Modeling

open access: yesAnnals of Neurology, EarlyView.
Objective Age of symptom onset is highly variable in familial frontotemporal lobar degeneration (f‐FTLD). Accurate prediction of onset would inform clinical management and trial enrollment. Prior studies indicate that individualized maps of brain atrophy can predict conversion to dementia in f‐FTLD.

Benefits of Categorizing Noncovalent Bonds Based on Hydrogen, Halogen, Chalcogen, and Pnictogen Bonds

open access: yesAngewandte Chemie, EarlyView.
A terminology for electrophile‐nucleophile interactions based on names that refer to the electrophile group/atom may offer the advantage to be descriptive, consistent, complete, systematic, clear, and, most important, invariant. Likely, a terminology that employs only the terms σ‐hole bond, π‐hole bond, and p‐hole bond may not.

CSF‐Compartmentalized Antibody Glycoprofiles in NMDAR Encephalitis Associate with Etiology and Functional Recovery

open access: yesAnnals of Neurology, EarlyView.
Objective To characterize Fc‐glycosylation profiles in patients with anti‐N‐methyl‐D‐aspartate receptor encephalitis (NMDARe) and assess their association with antibody compartmentalization (cerebrospinal fluid [CSF] vs serum), disease triggers (viral, tumor‐related or idiopathic), and 1‐year outcomes.

High Prevalence of SOD1 Pathogenic Variants in the UK Biobank: Implications for Early Intervention in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective SOD1 is the second most frequently mutated gene in European patients with amyotrophic lateral sclerosis (ALS). Given the recent authorization of SOD1‐targeted antisense oligonucleotides for SOD1‐ALS, prompt screening for SOD1 mutations in patients with ALS patients is highly recommended.

Protein‐Template Gold Nanoclusters Induce Differentiation and Modify the Functional Properties of Primary Astrocytes

open access: yesAdvanced NanoBiomed Research, EarlyView.
The incubation of primary astrocytes with fAuNCs‐BSA induces: (A) long‐term effects including fAuNCs‐BSA internalization, red cell fluorescence, differentiation, upregulation of Ca2+ signaling, Cl‐current, and cell volume regulation. B) Short‐term (200 ms) stimulation with UV LED light increases in Ca2+ signaling and inhibition of K+ current. Astrocyte

Translating Biomedical Research to Medical Devices: A Practical Guide and the Arteriovenous Graft Case Study

open access: yesAdvanced NanoBiomed Research, EarlyView.
Despite significant advances, most academic research fails to result in medical products that benefit patients. This guide shares five key steps to help researchers close that gap: set clear goals, test thoroughly, protect ideas, build diverse teams, and partner with industry.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to
