OBJECTIVES The determination of cholinesterase activity has been commonly applied in the biomonitoring of exposure to organophosphates and carbamates and in the diagnosis of poisoning with anticholinesterase compounds. One of the groups who are at risk of pesticide intoxication are the workers engaged in the production of these chemicals. AIMS The aim of this study was to assess the effect of...

Abstract This an apologia to Williams, P. F. (2022). The decline of substance over form in accounting: A problematic dichotomy. Accounting, Economics, and Law: Convivium critique Fischer, D., Ellman, O., & Schochet, S. (2021). accounting. , 20190052 article about the concept “substance form” has traditionally been a guiding principle for practicing accountants. In recent years, FASB taken a...

This paper presents a protocol for routine assays of human blood cholinesterase activities which separates erythrocytes from plasma by centrifugation and measures acetylcholinesterase activity in unwashed erythrocytes and butyrylcholinesterase activity in the plasma. The recommended substrate for both enzymes is 1.0 mM acetylthiocholine. The protocol is compared with other two recommended proto...

Four new mexicanolide-type limonoids 1-4, along with two known limonoids 5-6, were isolated from the ethanolic extracts of roots of the Traditional Chinese Medicine Trichilia sinensis. Their structures were unambiguously determined by analysis of spectroscopic data, including 1D and 2D NMR as well as MS, and by comparison with literature data. In addition, the acetylcholinesterase (AChE) inhibi...

It is well known that lung affections may be accompanied by so-called hypertrophic pulmonary osteo-arthropathy, which seems to be almost regularly associated with mild joint symptoms. Bamberger (1889) and Marie (1890) first studied this syndrome, but little attention has been paid to the misleading resemblance of these joint symptoms to those seen in the early stages of rheumatoid arthritis, th...

We describe here a field method we developed for colorimetry of erythrocytic acetylcholinesterase (EC 3.1.1.7) in capillary blood samples. Three stable, premixed assay reagents and de-ionized water (but no centrifuge or balance) are required. This method, adapted for a microplate format, is essentially that of Ellman et al. (Biochem Pharmacol 1961;7:88-95) as modified by George and Abernethy (C...

Pulmonary involvement with Hodgkin's disease has been estimated to occur in 40% of most large series (Ellman and Bowdler, 1960; Sternberg, Sidransky and Ochsner, 1959). Primary pulmonary Hodgkin's disease is most uncommon, and in Kern's review of the literature only 18 cases were noted to fulfill the criteria that were established by the authors (Kern, Crepeau and Jones, 1961). Since that time ...

Background We aimed to investigate different biological properties of aerial parts essential oil of Ferulago trifida Boiss and larvicidal activity of its volatile oils from all parts of plant. Methods Essential oil was prepared by steam distillation and analyzed by Gas chromatography and GC/Mass. Antioxidant, antimicrobial, cytotoxic effects and AChE inhibitory of the oil were investigated us...

We present a case of a 45-year-old patient who reported bleeding hemorrhoids. He had grade II hemorrhoids and was found to have a circumferential leukoplakic lesion at the anal verge. The patient had no symptoms of leukoplakia. The hemorrhoids were ablated with an Ellman radiowave device. Histological findings of the incised lesion from the verge showed hyperkeratosis and acanthosis extending c...
