organophosphate chronic toxicity has been evaluated in this study. biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. we have studied 17 occupationally exposed persons to pesticides. using ellman's colorimetric method, their plasma cholinesterase activities have been measured. results show that the appea...

A chemiluminescence method for determining acetylcholinesterase activity is described. It is an adaptation of the chemiluminescence assay of acetylcholine described by Israël & Lesbats [(1981) Neurochem. Int. 3, 81-90; (1981) J. Neurochem. 37, 1475-1483]. The acetylcholinesterase activity is measured by monitoring the increase in light emission produced by the accumulation of choline or by dete...

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...

In this study, it was aimed to compare the antioxidant properties of extracts obtained from extraction olive leaves in Hatay province prepared with different solvents. For purpose, were extracted using pure methyl alcohol soxhlet and also by maceration 60% ethanol, 70% methanol, 90% acetone (v/v) distilled water. Total Flavonoid Content (TFC), Phenolic (TPC), Ferric Antioxidant Reducing Power (...

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...

As I have noted, these calculations yield the expected observed accuracy of S s and S c , counting a prediction model as successful when its predictions match the apparent class of new objects. To calculate the accuracy of these strategies in predicting the true class of new objects, simply let n 0 c =0. 8 Acknowledgements Thanks to Tom Ellman, who suggested viewing noise as a model shift in th...

In the current study, a number of alkaloids including retamine, cytisine, and sparteine (quinolizidine-type), yohimbine and vincamine (indole-type), scopolamine and atropine (tropane-type), colchicine (tropolone-type), allantoin (imidazolidine-type), trigonelline (pyridine-type) as well as octopamine, synephrine, and capsaicin (exocyclic amine-type) were tested in vitro for their inhibitory act...
