Serum p‐tau217 Is a Prognostic Indicator of Cognitive Impairment in Idiopathic REM Sleep Behavior Disorder

open access: yesAnnals of Neurology, EarlyView.
Objective Assess the performance of serum phosphorylated tau 217 (p‐tau217) and neurofilament light chain (NfL) in predicting risk of cognitive impairment or phenoconversion to dementia in individuals with iRBD. Methods We measured serum p‐tau217 and NfL levels by electrochemiluminescence across 4 polysomnographically confirmed iRBD cohorts (n = 300 ...

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

Assessing Angiogenic Properties In Vitro or In Ovo of Pre‐Crosslinked Alginate‐Dialdehyde‐Gelatin Hydrogels Incorporating Boron‐Doped Mesoporous Bioactive Glass Particles

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study examines the influence of boron‐doped mesoporous bioactive glass nanoparticles (MBGN) blended in cast and 3D‐printed pre‐crosslinked alginate‐dialdehyde‐gelatin (ADA‐GEL). Addition of 0.5% and 1% MBGN did not negatively affect the viability of human umbilical vein endothelial cells (HUVECs), or the sprouting of HUVEC spheroids.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

open access: yesThe Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...
