Neurotoxic esterase: Characterization of the solubilized enzyme and the conditions for its solubilization from chicken brain microsomal membranes with ionic, zwitterionic, or nonionic detergents
(Elsevier, 1987-05-01)
Neurotoxic esterase (NTE) is a membrane-bound protein found in highest concentration in brain and lymphocytes. The enzyme has no known physiological function, but its organophosphorylation and aging in neural tissue are ...
Composition and origin of summertime air pollutants at Deep Creek Lake, Maryland
(Elsevier, 1989)
A 1 month intensive summertime field study conducted in rural western Maryland resulted in a comprehensive set of fine particle, gaseous and meteorological data. Sulfur in the assumed form of ammonium sulfate accounted for ...
Solubilization of hen brain neurotoxic esterase in dimethylsulfoxide
(Elsevier, 1985-10-15)
Neurotoxic esterase is the putative site of initiation of organophosphorus-induced neuropathy. The protein is membrane-associated and will thus require solubilization before it can be purified. Its enzymic activity was ...
Comparison of methods of analysis of polychlorinated biphenyls in oils
(Elsevier, 1983)
In order to standardize and validate methods for the analysis of polychlorinated biphenyls in transformer oil, waste oil, hydraulic fluid and capacitor oil in the concentration range 30-500 ppm, a study was performed which ...
Atmospheric acidity measurements on allegheny mountain and the origins of ambient acidity in the Northeastern United States
(Elsevier, 1989)
Atmospheric acidity as HNO3(g), SO2(g), and aerosol H+ was measured on Allegheny Mountain and Laurel Hill in southwest Pennsylvania in August 1983. The aerosol H+ appeared to represent the net after H2SO4 reaction with ...
Kinetics of heat inactivation of phenyl valerate hydrolases from hen and rat brain
(Elsevier, 1987-10-01)
Heat inactivation was studied at 45, 50, 55, and 60[deg] for all of the phenyl valerate hydrolases (PVase), including neurotoxic esterase (NTE) and inhibitor-resistant esterase (IRE), in homogenates of hen or rat brain or ...
Effect of ambient humidity on dichotomous sampler coarse/fine ratios
(Elsevier, 1988)
Atmospheric aerosols were measured in August 1983 on Allegheny Mountain and Laurel Hill in southwestern Pennsylvania. Ambient humidity was observed to influence the coarse to fine particle ratios as determined by dichotomous ...
Evidence for the existence of neurotoxic esterase in neural and lymphatic tissue of the adult hen,
(Elsevier, 1982-03-15)
Hen brain and spinal cord contain a number of esterases that hydrolyze phenyl valerate (PV). Most of this activity is sensitive to inhibition by micromolar concentrations of paraoxon. Included among the paraoxon-resistant ...
Lymphocyte and brain neurotoxic esterase: Dose and time dependence of inhibition in the hen examined with three organophosphorus esters
(Elsevier, 1986-03-30)
Certain organic phosphorus esters produce sensorimotor axonopathy in man and other species. There is an excellent correlation between the capacity of an organophosphorus compound to produce axonopathy and its ability to ...
Partial characterization of neurotoxic esterase of human placenta
(Elsevier, 1983-01)
Neurotoxic esterase (NTE), the putative target for organophosphorus-induced delayed axonopathy, has been found in preparations of human placenta. The activity was primarily found in membrane-enriched fractions rather than ...
