Biosensors are sensitive and can be used as disposable sensors for environmental control. These biosensors are based either on inhibition of acyl cholinesterases acetylcholinesterase or butyrylcholinesterase) by organophosphorus compounds or on inhibition of enzymes phosphatases (acid or alkaline) or on direct detection of organophosphorus compounds by organophosphorus hydrolase. The state-of-t...
Essential Oils Composition, Anticholinesterase and Antioxidant Activities of Pistacia atlantica Desf
Chemical composition and in vitro antioxidant and anticholinesterase activities of essential oils obtained from leaves and flowers of Pistacia atlantica were studied. GC/GC-MS analyses of the essential oils afforded twenty-two compounds from flower oil and thirty from leaf oil. The antioxidant activity of the essential oils was determined using -carotene-linoleic acid, DPPH • and ABTS • -scav...
The visual and somatic sensory cortex were investigated. The activity of acetylcholinesterase and lactate dehydrogenase was similar in the pretrigeminal and non-operated cats. The activity of these two enzymes, as well as that of choline acetyltransferase, butyrylcholinesterase and acid phosphatase was similar 3 and 8 h after the pretrigeminal transection. Results support the possibility of uti...
Abstract: Two known quinolizidine alkaloids, lupanine and leontiformidine, were isolated from the tubers of L. leontopetalum subsp. ewersmannii. Lupanine having the highest inhibition of lipid peroxidation at 100 μg/mL among the tested samples indicated almost the same ABTS cation radical scavenging activity with BHT, αtocopherol and (+)-catechin at the same concentration. Lupanine and the alka...
The effect of tricresylphosphate (TCP) was studied in vitro and in vivo on the rat liver and brain enzymes acetylcholinesterase (ACC), butyrylcholinesterase (CHE), arylesterase (ARE), aliesterase (ALI), and the microsomal nicotinamide-adenine dinucleotide phosphate oxidase (NADPH2-oxidase) system. The results show that, in the male rat, TCP given intraperitoneally induces an increase in liver m...
