A novel series of meta-substituted ethanediamide and 2-butenediamide derivatives were synthesized and tested for their ability to inhibit electric eel acetylcholinesterase (AChE) and equine serum butyrylcholinesterase (BuChE). The synthesized compounds were evaluated against ChE enzymes using the colorimetric method described by Ellman et al. (Biochem. Pharmacol., 7, 1961). It was revealed that...

Alcoholic extracts of 8 different types of seaweeds from Iran's Persian Gulf were tested for their antimalarial and acetylcholinesterase enzyme (AChE) inhibitory activities for the first time. A modified Ellman and Ingkaninan method was used for measuring AChE inhibitory activity in which galanthamine was used as the reference. The antimalarial assay was performed using microculture radioisotop...

A Pichia pastoris (P. pastoris) cell surface display system of Bombyx mori acetylcholinesterase (BmAChE) was constructed and its bioactivity was studied. The modified Bombyx mori acetylcholinesterase gene (bmace) was fused with the anchor protein (AGα1) from Saccharomyces cerevisiae and transformed into P. pastoris strain GS115. The recombinant strain harboring the fusion gene bmace-AGα1 was in...

Rotator cuff tears are a common cause of shoulder pain and dysfunction that affect all kinds of people, from sedentary individuals to elite athletes. Surgical repair of rotator cuff tears aims to re-establish the shoulder’s normal anatomical structure with restoration of pain-free motion, strength, and function. Rotator cuff repair (RCR) has evolved from an all-open procedure to an arthroscopic...

The characteristic cutaneous rheumatoid nodule, described fully by Collins (1937) and Bennett, Zeller, and Bauer (1940), is composed of a central area of fibrinoid necrosis around which develops an encircling corona of closely packed mesenchymal cells, the great majority of which appear to be fibroblasts (Collins, 1937), and external to this is a zone of inflammatory tissue. Lesions with simila...

Court-ordered monitoring of blood cholinesterases (ChEs) from orchard workers in Washington State is underway. In 2008, the mean red blood cell acetylcholinesterase (AChE, EC 3.1.1.7) activity was 9.65 +/- 1.11 micromoles/min/ml (n = 1,793) and the mean serum (BChE, 3.1.1.6) activity was 5.19 +/- 0.90 micromoles/min/ml (n = 1,811). Determinations were made using the Ellman assay and automated e...
