Plasma and brain cholinesterase activities were determined in three wild bird species to assess their exposure to organophosphate and carbamate insecticides which are used in agriculture and public health. In the present study, we used an electrometric method for measurement of cholinesterase activities in the plasma and whole brain of three indigenous wild birds commonly found in northern Iraq...

Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia. The management of the blood glucose level is a critical strategy in the control of diabetes complications. Inhibitors of carbohydrate hydrolyzing enzymes have been useful as oral hypoglycemic drugs for the control of hyperglycemia especially in patients with type II disables mellitus. The goal of the present study...

Microalgae represent one of the most promising sources bioactive compounds for pharmaceutical and food industries. Among these bioactives, carotenoids could be highlighted due to their health-promoting effects, including anti-inflammatory, neuroprotective or antioxidant properties. In this study, diverse microalgae extracts enriched in carotenoids, from Haematococcus pluvialis, Nannochloropsis ...

Cholinesterase is widely distributed in the animal kingdom, but its function apart from its involvement in the process of cholinergic transmission is unknown. Recent evidence indicates a close association between lipids and cholinesterase. Hyperlipaemia in humans.(Cucuinau etal., 1968)andrabbits (Kutty etal., 1973) is associated with increased serum cholinesterase activity. Cholinesterase has b...

Arsenic is an environmental toxicant, and one of the major mechanisms by which it exerts its toxic effect is through an impairment of cellular respiration by inhibition of various mitochondrial enzymes, and the uncoupling of oxidative phosphorylation. Most toxicity of arsenic results from its ability to interact with sulfhydryl groups of proteins and enzymes, and to substitute phosphorus in a v...

A new method of producing butyrylcholinesterase (BChE) preparations, stable in storage and use, has been proposed. The BChE preparation is the enzyme co-immobilized with 0.2 M 5-5′-dithiobis (2-nitrobenzoic acid) starch or gelatin gel. All experimental preparations retain activity for at least 300 d. based on gel show higher but lower sensitivity to toxicants tested this study compared gel-base...
