Monoaminergic Networks of Cognitive and Behavioral Symptoms in Early Parkinson's Disease
Movement Disorders, EarlyView.Abstract Background Parkinson's disease (PD) is associated with several behavioral and cognitive symptoms, the neurobiological background of which is not yet fully understood. Objectives The aim was to investigate the association between monoamine function and four specific nonmotor symptoms in early PD using the Parkinson's Progression Markers ...

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To develop a self‐supervised scan‐specific deep learning framework for reconstructing accelerated multiparametric quantitative MRI (qMRI). Methods We propose REFINE‐MORE (REference‐Free Implicit NEural representation with MOdel REinforcement), combining an implicit neural representation (INR) architecture with a model reinforcement ...

Addiction, EarlyView.Abstract Background and aims Tobacco smoking is a major risk factor for cardiovascular and lung diseases. A better understanding of its neurobiological underpinnings will benefit the prevention of smoking‐related illnesses and mortality. Previous studies link smoking to increased iron concentration in the striatum, a central component of the brain's ...

Brain Pathology, EarlyView.We investigated neuropathological manifestations of hypothermia in 168 cases. Patients aged 65 years or more constituted 80% of the total cohort. Alzheimer's disease was the most common comorbidity, affecting 40% of all patients. Abstract There is a paucity of autopsy‐based studies providing detailed neuropathological characteristics of fatal ...

Brain Pathology, EarlyView.14‐3‐3 protein homeostasis is disrupted in Lewy body pathology, showing a diminution of six isotypes and overexpression of stratifin. The latter was associated with stratifin colocalization with tau pathology and reactive astrocytes. Platelets, as a peripheral biomarker source, mirrored inversely cortical 14‐3‐3 gene expression patterns in dementia ...
