Water‐Mediated Phosphoryl Wires Stabilize Pathological Tau Fibrils

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Extended 1D phosphoryl “wires” stabilize in‐register amyloid tau fibrils, as demonstrated by multiple‐quantum spin‐counting NMR, TEM, and MD simulations, using fibrils of tau peptide jR2R3‐P301L (tau295–313) with phosphorylation at S305 or Y310. ABSTRACT Hyperphosphorylation of tau is a hallmark of tauopathies, with specific phosphorylation sites ...

Multimodel Diffusion MRI Signatures in Atypical Parkinsonian Disorders

Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.
We implemented a diffusion MRI framework to analyze clinically compatible multishell data across 123 participants, including controls, Parkinson's disease (PD), corticobasal syndrome (CBS), and progressive supranuclear palsy Richardson's syndrome (PSP‐RS). Diffusion models included DTI, free‐water elimination (FWE), NODDI, and fixel‐based analysis (FBA)

Mapping Neurodegenerative Changes in Clinically Uncertain Parkinsonian Syndrome Patients Using Fast MR Spin TomogrAphy in Time‐Domain (MR‐STAT) Relaxometry at 3T

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 429-439, August 2026.
ABSTRACT Background MR Spin TomogrAphy in Time‐domain (MR‐STAT) enables accelerated multiparametric relaxometry (T1/T2). Previous relaxometry studies predominantly compared Parkinson's disease patients with healthy controls (HC). The potential of relaxometry to distinguish neurodegenerative from non‐neurodegenerative parkinsonism in clinically ...

Proteomic and Phosphoproteomic Characteristics of Multiple Brain Regions in Rhesus Macaques After SARS‐CoV‐2 Infection

MedComm, Volume 7, Issue 8, August 2026.
The study found that SARS‐CoV‐2 Omicron infection causes region‐specific inflammatory, immune, synaptic, and signaling disorders in the brain, and the predicted kinases and differentially expressed proteins may serve as potential targets for COVID‐19‐related drug discovery.

Biomarker‐Based Diagnosis and Care Pathways for Alzheimer's Disease in the Era of Disease‐Modifying Treatments: A Consensus Statement by Belgian Experts

European Journal of Neurology, Volume 33, Issue 8, August 2026.
ABSTRACT Background The recent approval of disease‐modifying therapies (DMTs) for early Alzheimer's disease (AD) marks a major shift in clinical practice. Biomarker confirmation of amyloid pathology is now required alongside clinical assessment, and blood‐based tests are improving accessibility.

Effects of Meal Consumption on Isotonic Lingual Endurance in Healthy Adults: A Multi‐Institutional Study

Journal of Oral Rehabilitation, Volume 53, Issue 8, Page 1436-1446, August 2026.
Isotonic tongue endurance was measured pre‐ and post‐meal using the Iowa Oral Performance Instrument (IOPI) in healthy younger (18–35 years) and older (≥ 65 years) adults. Older adults demonstrated greater isotonic endurance and longer mealtimes, with no sex differences in endurance.

Hummingbird sign in progressive supranuclear palsy disease

Journal of Research in Medical Sciences, 2012
Progressive supranuclear palsy (PSP) is characterized by slowness, rigidity, bradykinesia, repeated falls, downgaze limitation and dementia. Midbrain atrophy on magnetic resonance imaging is highly suggestive of PSP and is described as "hummingbird sign".
