Cholinesterase in Junction Nevus

Journal of Investigative Dermatology, 1963
!The neural origin of all intradermal nevus cells has been proposed on the basis of their cholinesterase activity and lack of tyrosinase in contrast to the junction nevus cell (1, 2). However, tyrosinase studies of intradermal nevi after ultraviolet irradiation reveal not only an intensified dopa reaction but also a positive tyrosinase reaction in ...

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

Cortical Effects of Dopamine Replacement Account for Clinical Response Variability in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Individual variability in clinical response to dopamine replacement therapy (DRT) is a key barrier to efficacious treatment for patients with Parkinson's disease (PD). A better understanding of the neurobiological sources of such interindividual differences is necessary to personalize DRT prescribing, inform future clinical ...

Positron Emission Tomography Imaging in Clinical Trials for Parkinson's Disease: Applications of Metabolic Brain Network Approach

Movement Disorders, EarlyView.
ABSTRACT Neuroimaging with positron emission tomography (PET) has been instrumental in elucidating neurobiological mechanisms behind therapeutical trials in Parkinson's disease (PD). A variety of medical and neurosurgical interventions have been evaluated using many radioligands that reveal molecular basis for target engagement and brain responses in ...
