Midbrain atrophy related to parkinsonism in a non-coding repeat expansion disorder: five cases of spinocerebellar ataxia type 31 with nigrostriatal dopaminergic dysfunction.

Cerebellum Ataxias 2021 Mar 30;8(1):11. Epub 2021 Mar 30.

Department of Neurology, Tokyo Metropolitan Neurological Hospital, 2-6-1 Musashidai, Fuchu, Tokyo, 183-0042, Japan.

Background: Spinocerebellar ataxia type 31 (SCA31) is caused by non-coding pentanucleotide repeat expansions in the BEAN1 gene. Clinically, SCA31 is characterized by late adult-onset, pure cerebellar ataxia. To explore the association between parkinsonism and SCA31, five patients with SCA31 with concomitant nigrostriatal dopaminergic dysfunction (NSDD) development, including three cases of L-DOPA responsive parkinsonism, were analyzed.

Clin Neurophysiol 2021 Feb 3. Epub 2021 Feb 3.

Department of Human Neurophysiology, School of Medicine, Fukushima Medical University, Fukushima, Japan.

Objective: To study whether the velocity profile of horizontal saccades could be used as an indicator of brainstem and cerebellar output dysfunction, depending on progressive supranuclear palsy (PSP) subtype.

Methods: We compared the velocity profiles in 32 PSP patients of various subtypes with 38 age-matched normal subjects, including Richardson syndrome (RS), PSP-parkinsonism (PSPp), and pure akinesia (PAGF), and cerebellar subtypes of PSP (PSPc).

Results: PSP patients showed reduced peak velocity along with increased duration, especially in the deceleration phase. Read More

Lacrimal dilator-facilitated incisionless vs. standard sub-Tenon's block: a randomized, prospective and non-inferiority comparative study.

Eye (Lond) 2020 Oct 1. Epub 2020 Oct 1.

Department of Anaesthesia, Khoo Teck Puat Hospital, Yishun Central 90, Singapore, Singapore.

Background/objectives: Standard sub-Tenon's block (STB) involves incision (dissection) of conjunctiva and Tenon's capsule with the help of blunt scissors and forceps, insertion of a blunt sub-Tenon's cannula under the Tenon's capsule and injection of local anaesthetic agent. STB is frequently associated with minor complications such as chemosis and postoperative subconjunctival haemorrhage but rare sight and life-threatening complications. To reduce these minor complications, several variations of incisionless STB have been described however, there are no comparative data. Read More

Analysis of nocturnal hypokinesia and sleep quality in Parkinson's disease.

J Clin Neurosci 2018 Aug 13;54:96-101. Epub 2018 Jun 13.

Department of Neurology and Suzhou Clinical Research Center of Neurological Disease, The Second Affiliated Hospital of Soochow University, Suzhou 215004, China; Institute of Neuroscience, Soochow University, Suzhou 215123, China. Electronic address:

Nocturnal hypokinesia/akinesia and sleep disorder are believed to be common in Parkinson's disease (PD), but are often underestimated. To date, only a few studies have focused on nocturnal symptoms related to motor function and sleep quality in PD patients, and the assessments were based mainly on the subjective descriptions of the patients. In this study, we assessed the relationships between motor symptoms and sleep quality in 29 PD patients (17 PD patients reporting impaired bed mobility (IBM) and 12 patients without IBM). Read More

Anti-Parkinsonian and anti-dyskinetic profiles of two novel potent and selective nociceptin/orphanin FQ receptor agonists.

Br J Pharmacol 2018 03 31;175(5):782-796. Epub 2018 Jan 31.

Department of Medical Sciences, Section of Pharmacology, University of Ferrara, Ferrara, Italy.

Background And Purpose: We previously showed that nociceptin/orphanin FQ opioid peptide (NOP) receptor agonists attenuate the expression of levodopa-induced dyskinesia in animal models of Parkinson's disease. We now investigate the efficacy of two novel, potent and chemically distinct NOP receptor agonists, AT-390 and AT-403, to improve Parkinsonian disabilities and attenuate dyskinesia development and expression.

Experimental Approach: Binding affinity and functional efficacy of AT-390 and AT-403 at the opioid receptors were determined in radioligand displacement assays and in GTPγS binding assays respectively, conducted in CHO cells. Read More

Targeted kinase inhibition relieves slowness and tremor in a model of LRRK2 Parkinson's disease.

NPJ Parkinsons Dis 2017 4;3:34. Epub 2017 Dec 4.

Department of Biology, University of York, York, YO1 5DD UK.

In a number of models of genetic Parkinson's disease (PD) flies climb more slowly than wild-type controls. However, this assay does not distinguish effects of PD-related genes on gravity sensation, "arousal", central pattern generation of leg movements, or muscle. To address this problem, we have developed an assay for the fly proboscis extension response (PER). Read More

D-512, a novel dopamine D receptor agonist, demonstrates greater anti-Parkinsonian efficacy than ropinirole in Parkinsonian rats.

Br J Pharmacol 2017 Sep 11;174(18):3058-3071. Epub 2017 Aug 11.

Behavioral Neuroscience Program, Department of Psychology, Binghamton University - State University of New York, Binghamton, NY, USA.

Background And Purpose: Symptoms of Parkinson's disease are commonly managed using selective dopamine D receptor agonists, including ropinirole. While D agonists are useful in early-stage Parkinson's disease, they tend to lose efficacy in later disease stages and do not appear to modify disease progression. We have recently developed a novel 'multifunctional' compound, D-512: a high-affinity D receptor agonist with antioxidant and other neuroprotective properties that may limit Parkinson's disease progression.
