Reduced maximal range of ocular movements and its response to acute levodopa challenge in Parkinson’s disease

IntroductionAlthough restriction of vertical ocular range of motion is known to be the hallmark of progressive supranuclear palsy (PSP), the maximal amplitude of ocular movement has not been quantitatively assessed despite of accumulating evidences of oculomotor dysfunction in Parkinson’s disease (PD). Here, we evaluated the maximal oculomotor range and its response to levodopa in PD, […]

Astrocyte expression of aging-associated markers positively correlates with neurodegeneration in the frontal lobe of the rhesus macaque brain

IntroductionAs the population over the age of 65 increases, rates of neurodegenerative disorders and dementias will rise – necessitating further research into the cellular and molecular mechanisms that contribute to brain aging. With the critical importance of astrocytes to neuronal health and functioning, we hypothesized that alterations in astrocyte expression of aging-associated markers p16INK4a (p16) […]
