The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Speech Biomarkers for Quantifying Effects of Subthalamic Deep Brain Stimulation in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Dysarthria is one of the most common and disabling side effects of subthalamic nucleus deep brain stimulation (STN‐DBS) in Parkinson's disease (PD). Stimulation often exacerbates speech dysfunction beyond the effects of PD progression, likely because of current spread to structures surrounding the STN.

Regional and Compartmental Changes Drive Progressive Patterns of Striatal Degeneration in X‐Linked Dystonia Parkinsonism

open access: yesAnnals of Neurology, EarlyView.
Objective Initially described in 1976, X‐linked dystonia parkinsonism (XDP) is a neurodegenerative disease that can be characterized by the presentation of dystonia and parkinsonism symptoms. Although this disease bears some resemblance to other neurodegenerative diseases in terms of symptomatology, the pathological signature of XDP is still unclear ...

A Novel Class of “Super‐Strained” Spiro Heterocycles: Gateway to 1‐Azaspiro[3.3]heptane Derivatives, and Biological Validation

open access: yesAngewandte Chemie, EarlyView.
A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

open access: yesAnnals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Beyond the Fixed Charge: A New On‐Tissue Derivatisation Strategy Employing Photoionisable Chromophores for Mass Spectrometry Imaging of Amino‐Containing Metabolites

open access: yesAngewandte Chemie, EarlyView.
We introduce a novel chemical derivatisation strategy for the UV‐activated detection of elusive metabolites. Incorporation of a tocopherol‐active chromophore allows for the detection of tagged analytes as photoionised radical cations, selectively induced by a 266 nm laser.
