Background: Parkinson’s disease (PD.) is one of the most common neurodegenerative disorders. There are many documents about the effects of oxidative stress on PD. progress. Angiotensin II activates NADPH depending on oxidases and these oxidases produce superoxides. Cerasus avium extract is an angiotensin converting enzyme )ACE( inhibitor in Invitro. Objective: Evaluation of neuroprotective eff...

Purpose: Modafinil is a vigilance-enhancing drug licensed for narcolepsy. The use of modafinil leads to various neuromodulatory effects with very low abuse potential. A body of evidence suggested that modafinil may have anti-parkinsonian effects. This study was designed to evaluate whether modafinil could improve motor dysfunction in the 6-hydroxydopamine (6-OHDA)-induced rat model of Parkinson...

Apolipoprotein E (ApoE) is mainly secreted by glial cells and is involved in many brain functions, including neuronal plasticity, β-amyloid clearance, and neuroprotection. Microglia--the main immune cells of the brain--are one source of ApoE, but little is known about the physiologic regulation of microglial ApoE secretion by neurons and whether this release changes under inflammatory or neurod...

There are nerves and nerve endings in the trabecular meshwork, but their structure does not reveal whether they are adrenergic or cholinergic in function. Tranzer and Thoenen have shown that the administration of 5-hydroxydopamine, a false sympathetic transmitter, fills the synoptic vesicles of adrenergic nerve endings with an electron dense material. Cholinergic nerve endings possess synaptic ...

Introduction Efficient delivery of rotigotine into the brain is crucial for obtaining maximum therapeutic efficacy for Parkinson's disease (PD). Therefore, in the present study, we prepared lactoferrin-modified rotigotine nanoparticles (Lf-R-NPs) and studied their biodistribution, pharmacodynamics, and neuroprotective effects following nose-to-brain delivery in the rat 6-hydroxydopamine model o...
