Blood Biomarkers of Alzheimer's Disease and Patterns of Structural Brain Changes in the Community

Annals of Neurology, EarlyView.
Objective We aimed to investigate the associations between Alzheimer's disease (AD)‐related blood biomarkers and changes in brain volumes and cerebrovascular burden in community‐dwelling older adults. Methods We included 361 dementia‐free participants with a Mini‐Mental State Examination (MMSE) score ≥ 27 and without prior cerebrovascular events from a

Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

Angewandte Chemie, EarlyView.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...

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

Annals 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 ...

Rational Design of a Synthetic Galliphore for the Diagnostic Nuclear Imaging and Treatment of Bacterial Infections

Angewandte Chemie, EarlyView.
KO‐NH2 is a synthetic metallophore that preferentially binds Ga3+ over Fe3+ and is recognized by bacterial transporters. Photocrosslinking identifies CirA and Fiu as key uptake proteins in E. coli. KO‐NH2 enables targeted imaging and treatment of E. coli soft tissue infections.

Cortical Thickness and White Matter Surface Morphology in Tourette Syndrome: A Cohort Study

Annals of Neurology, EarlyView.
Objective To examine cortical thickness and white matter surface morphology in a large sample of individuals with Tourette syndrome (TS) and neurotypical controls across the lifespan, and to assess associations with symptom severity, comorbidities, and medication use.

Hippocampal Seizure‐Related Burden is Associated with Accelerated Long‐Term Forgetting in Focal Epilepsy

Annals of Neurology, EarlyView.
Objective Memory impairment is a frequent comorbidity of focal epilepsy, incompletely explained by seizure frequency or structural pathology. Ictal and postictal hippocampal dysfunction disrupt memory processes, but their cumulative impact remains poorly quantified.

Deep learning based bilateral filtering for edge-preserving denoising of respiratory-gated PET

EJNMMI Physics
Background Residual image noise is substantial in positron emission tomography (PET) and one of the factors limiting lesion detection, quantification, and overall image quality. Thus, improving noise reduction remains of considerable interest.

Positron annihilation studies of defects in Si1-xGex/SOI heterostructures

, 2009
The strain of a SiGe alloy epitaxially grown on Si can be released by heating at 750°C. However the strain relaxation is accompanied by the generation of threading dislocations and associated point defects.

Genetic Resilience and Resistance in Alzheimer's Disease Diagnosis and Pathology

Annals of Neurology, EarlyView.
Objective Some individuals avoid Alzheimer's disease (AD) pathology as they age, or retain cognition despite substantial pathology, suggesting mechanisms of resistance or resilience to neurodegeneration. Educational attainment (EA) is associated with reduced risk of cognitive decline, although the underlying mechanisms remain unclear.
