a b s t r a c t   alzheimer's disease (ad) is a neurodegenerative disorder in geriatric people that characterized by reduction in memory and learning ability. attenuation of cholinergic system is the most likely hypothesis. therefore, potentiation of the cholinergic system via inhibition of acetylcholinesterase enzyme could improve and alleviate the symptoms of ad. a new series of isatin-based ...

Members of the genus Lathyrus are used as food and as traditional medicines. In order to find new sources of biologically-active compounds, chemical and biological profiles of two Lathyrus species (L. czeczottianus and L. nissolia) were investigated. Chemical profiles were evaluated by HPLC-ESI-MSn, as well as by their total phenolic and flavonoid contents. In addition, antioxidant, enzyme inhi...

Spondias mombin has been used in traditional medicine for the management of several diseases, including memory loss. This study aimed to evaluate the cholinesterase inhibitory activity of the methanol extract of the leaves and its derived fractions, as well as carry out detailed phytochemical investigations leading to the isolation and characterization of bioactive compounds from the plant. The...

In this work, deep eutectic solvents (DES-based menthol and cholinium chloride) the ethanol, temperature, times were selected to extract bioactive compounds from rhizome, leaves, flowers Curcuma longa L., using ultrasound-assisted extraction. Analyzes antioxidant, flavonoids, antimicrobial, chelation Fe2+, inhibition of cholinesterase's enzymes, cytotoxicity, genotoxicity in Allium cepa cells p...

We report a two-day-old infant who had a period of apnoea lasting six hours following the intravenous administration of succinylcholine (Sch). The results of her plasma cholinesterase level and dibucaine number indicate a congenital absence of plasma cholinesterase (PChE) enzyme, although both parents and siblings had normal cholinesterase levels and dibucaine numbers. This is believed to be th...

diazinon is one of the highly consumed organophosphorous pesticides. it inhibits cholinesterase enzyme in animal tissues. due to permanent residence in agricultural drainage channels, the swan mussel (anodonta cygnea) can be considered as one of the most suitable indicators of such pollutants. at the present study, acethyle cholinesterase activity of a. cygnea was measured when exposed to vario...

A histochemical staining technique for cholinesterase is reported for the study of corneal nerves in whole-thickness rabbit cornea. The technique is relatively simple, yields reproducible results, allows good definition of the nerve fiber pattern, and provides the investigator, using a binocular microscope, with the advantage of three-dimensional study. When tissue is stained for specific choli...
