Striatal Dopaminergic Reserve Shapes the Longitudinal Impact of Peripheral Immune Activation on Motor Progression in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Peripheral immune dysregulation has been implicated in Parkinson's disease (PD) progression, but whether motor deterioration reflects accelerated nigrostriatal degeneration or residual dopaminergic reserve remains unclear. Objectives To examine whether baseline and time‐varying neutrophil‐to‐lymphocyte ratio (NLR) relate to motor ...

Neuropsychiatric and Cognitive Symptom Evolution over the First Decade of Biomarker‐Positive, Sporadic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is frequently accompanied by neuropsychiatric symptoms (NPS), including cognitive impairment, which often emerge early and co‐occur. Their long‐term evolution remains incompletely characterized, particularly in biomarker‐positive cohorts.

Cerebellar Network Organization in Parkinson's Disease: Functional Connectivity across Motor and Cognitive Circuits

open access: yesMovement Disorders, EarlyView.
Abstract Background The cerebellum is increasingly recognized as a key contributor to cognitive reserve and network organization in Parkinson's disease (PD). However, the relationship of cerebello‐cortical and cerebello‐basal ganglia connectivity with cognitive status and nigrostriatal integrity remains incompletely understood.

Neuromelanin‐Sensitive MRI as a Marker of Clinical Severity and Disease Burden in Parkinson's Disease: A Systematic Review and Meta‐analysis

open access: yesMovement Disorders, EarlyView.
Abstract The neuropathology of Parkinson's disease (PD) is characterized in part by the degeneration of catecholaminergic neurons, particularly dopaminergic neurons in the substantia nigra pars compacta (SNpc) and noradrenergic neurons in the locus coeruleus (LC), yet no validated in vivo biomarker quantifies this process.

Independent Component Analysis for Non‐Contrast‐Enhanced Free‐Breathing Pulmonary Ventilation and Perfusion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce a robust approach for non‐contrast‐enhanced free‐breathing functional lung MRI based on independent component analysis (ICA), addressing key limitations of standard methods such as sensitivity to irregular breathing or irregular heartbeat.

177Lu‐labeled amidoxime‐functionalized biodegradable microspheres for transarterial radioembolization of hepatocellular carcinoma

open access: yesPrecision Radiation Oncology, EarlyView.
Scheme 1. Schematic illustration of the synthesis and therapeutic evaluation of PLA‐g‐PAO microspheres (PLA‐g‐PAO‐Ms). Monodisperse PLA microspheres (PLA‐Ms) were initially fabricated via microfluidic technology. Surface grafting of acrylonitrile monomers was subsequently achieved through radiation‐induced graft polymerization, followed by ...

Asthma: From Phenotypes to Endotypes—Beyond Type 2 Inflammation

open access: yesRespirology, EarlyView.
ABSTRACT Asthma is a heterogeneous syndrome featuring variable pathophysiology, clinical presentation and treatment response. This review examines a comprehensive endotype‐phenotype framework for asthma assessment with an emphasis on characteristics beyond T2 inflammatory status alone.
