Dysfunctional Light-Evoked Regulation of cAMP in Photoreceptors and Abnormal Retinal Adaptation in Mice Lacking Dopamine D4 Receptors [PDF]
, 2002 Dopamine is a retinal neuromodulator that has been implicated in many aspects of retinal physiology. Photoreceptor cells express dopamine D4 receptors that regulate cAMP metabolism.

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction
Advanced Science, EarlyView.The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

Journal of Neurology, Neurosurgery & Psychiatry, 1974 In 10 patients with Parkinsonism, treatment with L-dopa was associated with a rise in the skin conductance level and its fluctuations, an increased electromyographic activity in the frontalis muscle, and with faster reaction times. The change of skin conductance in response to a loud noise also increased and its habituation to the repetition of the ...

Myoclonus-dystonia : distinctive motor and non-motor phenotype from other dystonia syndromes [PDF]
, 2019 Background: myoclonus-dystonia (M-D) due to a pathogenic variant of SGCE is an autosomal dominant inherited movement disorder. Apart from motor symptoms, psychiatric disorders are highly prevalent in patients with MD.

Advanced Science, EarlyView.Neuroinflammation alters blood–brain barrier integrity and contributes to neurological disorders, yet existing models lack human immune complexity. This study presents a 3D, immune‐responsive platform that reconstructs key neurovascular components and enables real‐time monitoring.

Striatal proteomic analysis suggests that first L-dopa dose equates to chronic exposure. [PDF]
PLoS ONE, 2008 L-3,4-dihydroxypheylalanine (L-dopa)-induced dyskinesia represent a debilitating complication of therapy for Parkinson's disease (PD) that result from a progressive sensitization through repeated L-dopa exposures. The MPTP macaque model was used to study

Pain-motor integration in the primary motor cortex in Parkinson's disease [PDF]
, 2017 In Parkinson's disease (PD), the influence of chronic pain on motor features has never been investigated. We have recently designed a technique that combines nociceptive system activation by laser stimuli and primary motor cortex (M1) activation through ...
