An electrochemical sensor is introduced as a tool applicable for diagnosis of intoxication by cholinesterase inhibitors caused by the well-known nerve agent VX. The traditional Ellman method was chosen for comparison with the sensor's analytical parameters. Both methods are based on estimation of blood cholinesterase inhibition as a marker of intoxication. While Ellman´s method provided a limit...
The procedure of Dietz et al. (Clin. Chem. 19: 1309-1313, 1973) for plasma cholinesterase (EC 3.1.1.7) gives a background absorbance of 1.4 A when extended to erythrocyte cholinesterase (EC 3.1.1.8) measurement, because the peak absorbance of the reaction product, 5-thionitrobenzoate, coincides with the hemoglobin Soret band at 410 nm. Consequently, the precision of erythrocyte cholinesterase m...
factors such as oxidative stress and reduced acetylcholine level have been implicated in alzheimer’s disease (ad) pathology and recently there has been a trend towards natural product research to find potential sources of antioxidants and acetylcholinesterase inhibitors in the plants kingdom. centaurea is a genus with about 500 species world wild, many of them have shown to possess biologic act...

Reimagining HIV service delivery: the role of differentiated care from prevention to suppression Anna Grimsrud, Helen Bygrave, Meg Doherty, Peter Ehrenkranz, Tom Ellman, Robert Ferris, Nathan Ford, Bactrin Killingo, Lynette Mabote, Tara Mansell, Annette Reinisch, Isaac Zulu and Linda-Gail Bekker Corresponding author: Anna Grimsrud, Cnr Albion Springs & Main St, Rondebosch, Cape Town 7700, South...
objective(s): alzheimer’s disease (ad) as progressive cognitive decline and the most common form of dementia is due to degeneration of the cholinergic neurons in the brain. therefore, administration of the acetylcholinesterase (ache) inhibitors such as donepezil is the first choice for treatment of the ad. in the present study, we focused on the synthesis and anti-cholinesterase evaluation of n...
We report a case of multiple fistulae in ano [8 external openings] in a 45-yrs-old man, who had a history of episodes of pain and pus discharge from openings around the anus since 4 years. Biopsy from the tract of one of the fistula confirmed tubercular infection. He underwent radiofrequency fistulotomy using a Ellman radiofrequency device along with anti-tubercular treatment, which resulted in...
