Besides chorea, rarer types of LIDs include myoclonic dyskinesia, ocular dyskinesia, and respiratory dyskinesia.1 Oromandibul...

Flow-metabolism dissociation in the pathogenesis of levodopa-induced dyskinesia

Levodopa-induced dyskinesia (LID) is the most common, disruptive complication of Parkinson’s disease (PD) pharmacotherapy, yet despite decades of research, the changes in regional brain function underlying LID remain largely unknown. We previously found that the cerebral vasomotor and metabolic responses to levodopa are dissociated in PD subjects. Nonetheless, it is unclear whether levodopa-med...

Synaptic Plasticity and Levodopa-Induced Dyskinesia: Electrophysiological and Structural Abnormalities
Journal of Neural Transmission;

Parkinson's disease (PD) is a neurodegenerative disorder characterized by progressive degeneration of dopaminergic neurons located in the midbrain. The gold-standard therapy for PD is the restoration of dopamine (DA) levels through the chronic administration of the DA precursor levodopa (L-DOPA). Although levodopa therapy is the main therapeutic approach for PD, its use is limited by the develo...

Coronavirus misinformation, and how scientists can help to fight it

Eating sea lettuce or injecting disinfectant won’t prevent you from getting COVID-19. Holding your breath for ten seconds is not a test for SARS-CoV-2. And Russian President Vladimir Putin did not release 500 lions in Moscow to persuade the city’s residents to stay indoors as part of the efforts to fight the pandemic. The rapid global spread of COVID-19 has been accompanied by what the World He...

These restrictions have been introduced to help maintain physical di...

New Method to Reduce COVID-19 Transmission - The Need for Medical Air Disinfection is Now

The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) [1]. It has led to a pandemic worldwide due to its extremely infectious nature. At present, the route of transmission of SARS-CoV-2 is still controversial, but the major route of the COVID-19 to rapidly spread through indoor environments, is caused by the airborne route of the ...

What aerosol physics tells us about airborne pathogen transmission

While a global pandemic by SARS-CoV in 2002–2003 was averted by fast identification, effective surveillance, and quarantine, such measures cannot be easily transferred to new situations, as the case of SARS-CoV-2 demonstrates. Knowledge of the fundamental biological and physical parameters affecting transmission pathways of respiratory pathogens is thus critical for the design of effective non-...
