Corticobasal syndrome, progressive supranuclear palsy and frontotemporal dementia are all part of a disease spectrum that includes common cognitive impairment and movement disorders. The aim of this study was to characterize brain cholinergic deficits in these disorders. We measured brain acetylcholinesterase activity by [11C] N-methylpiperidin-4-yl acetate and positron emission tomography in s...
Musical hallucinations are relatively rare auditory percepts which, due to their intrusive nature and the accompanying fear of impending mental decline, tend to cause significant distress and impairment. Although their etiology and pathophysiology appear to be heterogeneous and no evidence-based treatment methods are available, case reports indicate that acetylcholinesterase inhibitors may yiel...
The ability of Caenorhabditis elegans to recover from exposure to high doses of aldicarb and fenamiphos was examined at the organismal and biochemical levels by determination of movement and acetylcholinesterase activity. Nematodes recovered rapidly from a 24-hour exposure to both compounds at concentrations that caused complete paralysis. Acetylcholinesterase regained nearly full activity afte...
Rivastigmine transdermal patch is indicated for patients with Alzheimer's disease and dementia with Parkinson's disease. Rivastigmine, an acetylcholinesterase inhibitor, has several common adverse effects, mainly involving the gastrointestinal tract, but few cardiovascular adverse effects have been reported. This report presents two cases of patients presenting with 3(rd) degree atrioventricula...
Sections of cat ciliary ganglia were stained for acetylcholinesterase activity by several modifications of the acetylthiocholine method in order to achieve optimal accuracy of cytological localization of the enzyme. These were compared by ordinary light and phase contrast microscopy with similar sections stained by standard techniques for Nissl substance, the Golgi apparatus, and the neurofibri...
In this study, we have employed in silico methodology combining double pharmacophore based screening, molecular docking, and ADME/T filtering to identify dual binding site acetylcholinesterase inhibitors that can preferentially inhibit acetylcholinesterase and simultaneously inhibit the butyrylcholinesterase also but in the lesser extent than acetylcholinesterase. 3D-pharmacophore models of ACh...
The therapeutical efficacies of eleven oxime-based acetylcholinesterase reactivators were compared in an in vivo (rat model) study of treatment of intoxication caused by tabun. In this group there were some currently available oximes (obidoxime, trimedoxime and HI-6) and the rest were newly synthesized compounds. The best reactivation efficacy for acetylcholinesterase in blood (expressed as per...
